Biography

Volker Wulf is a Professor of Information Systems and New Media at the University of Siegen and a founding member of the International Institute for Socio-Informatics (IISI). He was Visiting Professor at Stanford University and research fellow at the University of Michigan as well as the Massachusetts Institute of Technology (MIT).

He shaped the research field of Socio-Informatics as an activist-leaning endeavour to tackle societal problems in a bottom-up participatory manner. Socio-Informatics intertwines empirical studies of social practices with the design of ICT artefacts and their infrastructuring in real-world settings. Volker’s work is inspired by local demands in the rural but industrialized region around his university as well as by global challenges such as ICT appropriation under oppressive rule, in (civil) wars, or by refugees and migrants. His academic work contributes to the fields of Human Computer Interaction, Computer Supported Cooperative Work, Communities & Technologies, End User Development, and Participatory Design.

He published more than 500 papers and 20 books among which “Expertise Sharing: Beyond Knowledge Management“ and „Social Capital and Information Technology“ both with MIT Press, „End User Development“ with Springer, and “Socio-Informatics - A Practice-based Perspective on the Design and Use of IT Artefacts,” with Oxford University Press are probably the best known.

AI authoring for VR-supported layout and process planning: methodological concept for the turning shop of the future
In: i-com, DOI: 10.1515/icom-2025-0047
Schlagwörter: AI authoring; digitalisation; layout and process planning; methodological concept; virtual reality; visual components
Abstract Links

This article introduces a new design concept for visually planning and optimising production layouts for the turning shop of the future. The planning process takes place within the Visual Components software in a virtual reality (VR) environment, combining Low-Code and Pro-Code approaches for implementation. Existing components can be imported into the 3D environment and edited flexibly via a central database. In addition, computer-aided design (CAD) models of relevant machines can be integrated. However, as the degree of realism increases, so does the development effort. Authoring with artificial intelligence (AI) and large language models (LLMs) can facilitate the necessary programming, enabling development even for users without programming experience. This can significantly increase the attractiveness and usefulness of such VR applications. A well-established provider of consulting, training and engineering solutions in machining technology and automation acted as an application partner for this solution’s demonstrator. This article demonstrates how AI authoring, when combined with VR technology, can create an effective and practical tool for production planning, which could become an integral part of modern manufacturing operations.

Working Practices in Welding: A Qualitative Study on Knowledge and Expertise Sharing in the Welding Industry
In: Computer Supported Cooperative Work (CSCW), Volume: 35 No.:2, S. 10, DOI: 10.1007/s10606-026-09544-6
Schlagwörter: Empirical study; Embodied knowledge; Assistance systems; Welding
Abstract Links

This study investigates issues of (KES) in conventional manufacturing processes concerning the use of welding. In view of the shortage of skilled workers and the advancing digitalisation processes in welding, it is essentially relevant to identify how KES takes place. Based on an in-depth study, the possibilities of digital assistance systems to support KES in welding are discussed. The novelty of our contribution lies in the use of a (CSCW) perspective to understand how welding practices can be supported and shared among co-workers. Such practices, as made evidence across the contribution, have particular aspects that make them unique in comparison with other practices in the metal-working industry. Technologies that are already available offer promising possibilities to the challenges faced by KES in welding and have the potential to shape a third generation of KES. While operational activities can benefit from visual digital support, administrative and managerial tasks primarily require better access to relevant information and a better understanding of the practice. Our contribution offers valuable insights for the further development of KES in industrial manufacturing processes and show potential for the targeted use of innovative technologies in welding. It also adds to the CSCW body of literature on KES, by contributing an empirical study on a domain not well explored in the field.

Silencing & Surging: A Layered Ecology of Algorithmic Repression and Resistance in the Gaza Escalations
S. 1–16, DOI: 10.1145/3772318.3790994
Abstract Links

During the 2023–ongoing Gaza war, Palestinian advocacy on social media has faced rapid removals, downranking, and account sanctions. In this contribution, we offer a layered analysis of how people endure and counter this repression across affective, mechanistic, and material dimensions. Using patchwork ethnography over 295 first-person testimonies and 85 NGO/press documents, we identify a recursive Contest Loop: hostile mass-report brigades and automated enforcement that spur supporter “appeal brigades,” mirroring, and migration. Findings are organized as a three-layer ecology—Invisible Scars (whiplash, shadowbanning as probabilistic throttling, self-censorship), Dueling Brigades (frictions, coordinated reports, supporter procedures), and Feed-to-Street Ripples (fundraising, evidentiary preservation, livelihoods). Conceptually, we extend platform-assemblage thinking with a Resistance Assemblage: ad-hoc technical, emotional, and legal mutual-aid infrastructures that keep visibility alive under sanction. We contribute: (1) an event-centered, experience-near account of co-produced moderation in conflict; (2) two integrative lenses (Contest Loop, Resistance Assemblage); and (3) design/policy directions, including collective-appeal dashboards, and evidentiary safeguards that separate archiving from distribution.

From Distribution to Contribution: Negotiating Justice Policies in Grassroots FOSS Communities
S. 1–17, DOI: 10.1145/3772318.3791722
Abstract Links

Fairness is a recurring challenge in grassroots digital infrastructures, where collective action depends on volunteer contributions. This paper presents a study of Foodsharing.de, a grassroots FOSS platform with 185,000 members rescuing and redistributing surplus food. Drawing on 25 interviews and long-term activist involvement, we analyze two justice-oriented features: the Cherry-Picking Rule (distributional fairness) and Commitment Statistics (contributional fairness). We show how these fairness features become deeply entangled in practice and how they operate as policy-in-code, inscribing fairness logics into software and redistributing not only food and labor but also authority within the community. Rather than settling questions of justice, these interventions trigger renewed negotiation across deliberative spaces and everyday coordination, as encoded rules are interpreted, contested, and adapted. Building on these dynamics, we outline governance directions for justice-oriented grassroots infrastructures, highlighting the need for contestability and accountable autonomy to sustain negotiation and align technical change with community legitimacy.

Embodied AI in the Wild: Comparing Older Adults’ Interactions with an Avatar and a Humanoid Robot in a Public Space
S. 1331–1347, DOI: 10.1145/3800645.3813040
Abstract Links

Although embodied AI systems are increasingly developed and tested in public environments, their influence on the design of products for older adults remains underexplored. We examine how different types of embodiment, or form factor, shape initial encounters between humans and AI when conversational abilities are comparable. Building on prior work, we conducted a two-day field study at a senior citizens’ fair in Germany (n = 25, age 24–90), where participants interacted with the screen-based avatar Ann-Sophie and the humanoid robot Ameca. Both used LLM-based dialogue systems, enabling a focus on embodied interaction rather than linguistic performance. Qualitative results show contrasting affective and social responses: Ameca’s physical presence and gaze dynamics were described as both fascinating and unsettling, while Ann-Sophie was perceived as warm but socially limited. These findings highlight the role of embodiment in shaping comfort, expectations, and ethical awareness in public human–AI interaction.

From Using to Infrastructuring: Grassroots VPN-Building in Iran’s Women–Life–Freedom Movement
S. 1–30, DOI: 10.1145/3772318.3790369
Abstract Links

States increasingly weaponize digital infrastructures through censorship and surveillance. Iran represents an acute case of this broader global pattern. We study how citizens sustain connectivity and agency during Iran’s Women–Life–Freedom (WLF) protests. Based on 21 interviews with citizens and digital activists in Kermanshah province, inside Iran and in the diaspora, we document a shift from dependence on commercial circumvention to grassroots infrastructuring: people created and shared VPNs, proxies, and ad hoc communication pipelines. Peer learning on platforms such as Telegram, X, and GitHub—via Persian tutorials, scripts, and troubleshooting—enabled rapid adaptation under repression. We identify four dynamics: (1) distrust and survival as primary motivations; (2) infrastructural solidarity as everyday care; (3) technical improvisation and peer teaching; and (4) persistent constraints from censorship and risk. We argue that grassroots infrastructuring reframes end-user development as survival work. The paper contributes empirical evidence and design implications for HCI/CSCW on civic technologies, digital activism, and infrastructures of participation under authoritarian control.

How to successfully fail a design case study
In: i-com, DOI: 10.1515/icom-2025-0035
Schlagwörter: data infrastructure; data work; digital transformation; human-computer interaction in SMEs; knowledge management
Abstract Links

Small and medium-sized enterprises (SMEs) in rural regions face major challenges in the digital transformation. Historically grown IT landscapes, limited resources, outdated processes, and a strong dependence on external service providers make further development and digitalization difficult. Against this backdrop, the present study reports on a design case study within a German industrial company located in a rural region that only went up to prototype development. Data work, data management (DM), and knowledge exchange practices were analyzed using interviews, observations, and subsequently a prototype was designed using a participatory design approach. The results reveal duplicate data entries, knowledge silos, and a lack of system integration, all of which impair data quality and collaboration. Although the prototype was not implemented within the time window of the project, it functioned as a boundary object that surfaced ownership and process knowledge and informed the decision to replace the existing IT landscape with a larger, integrated solution. The study contributes to CSCW by promoting a design-for-knowledge perspective that shows how design work prior to appropriation in SMEs builds a common understanding and reveals the actual needs of the organization.

Designing for workplace well-being: a design case study using aromatherapy as a provocation
In: i-com, DOI: 10.1515/icom-2025-0045
Schlagwörter: digitalization; SMEs; sociotechnical; well-being; workplace
Abstract Links

This paper presents the first design iteration of a case study conducted in a pharmaceutical distribution company to investigate the sociotechnical dimensions of managing stress. Aromatherapy is employed both as a design provocation and as a well-being intervention, aiming to uncover the underlying design imperatives of workplace well-being interventions. We conceptualize the workplace as a sociotechnical infrastructure and emphasize the situated and contextual nature of work practices as central to understanding stress. The case study contributes to HCI research by (1) advancing the understanding of stress as a sociotechnical issue in organizational contexts and (2) offering insights into the design and use of aromatherapy as a non-conventional well-being intervention in the workplace, identifying broader implications and tensions for the design of such technologies.

Invisible work and unpredictable challenges in clinical practice: results from a participatory design case study
In: i-com, DOI: 10.1515/icom-2025-0041
Schlagwörter: design case study; healthcare technology; invisible work; nursing workload; robotic assistance
Abstract Links

The shortage of professional caregivers and an aging population in Western countries contribute to high workloads in hospitals, which can negatively affect patient care and increase nurse turnover. Robotic assistance has the potential to alleviate these workloads. We conducted a design case study to identify application scenarios to reduce nurses’ administrative challenges. We found that tasks such as patient admissions and escorting patients to in-house medical appointments often constitute invisible work, which can be supported by a robot. Observations and follow-up semi-structured interviews with nursing staff highlight the potential of robots to reduce workload. At the same time, successful implementation requires considering the perspectives of multiple stakeholders, including nursing staff, patients, and bystanders. Moreover, our findings show that invisible human work by nurses was often needed to maintain the robot’s functionality.

Engaging in Sensitive Practices: Insights and Challenges from a long-term Participatory Design Project with People with Dementia
In: Computer Supported Cooperative Work (CSCW), Volume: 35 No.:2, S. 4, DOI: 10.1007/s10606-026-09538-4
Schlagwörter: Dementia; Qualitative research; Participatory design; ICT; Exergame; Videogame
Abstract Links

Over the past decade, a range of methodological approaches, user studies, and research results focused on technology for people with dementia has led to insights into the design of innovative solutions that can be embedded in the complex daily lives of people with dementia and their care-network. This paper recounts experiences and lessons learned over the course of a three-year participatory design project with and for people with dementia and their caregivers in domestic and institutional care settings. It contributes with long-term insights and reflections on the challenges confronting researchers in these sensitive care domains and discusses the need to 'know the users' and their care-networks so as to enable a deeper understanding of their unique difficulties. In particular, it examines the relationship between empathic understanding, experience-centered design, and the social appropriation of ICT, in our case exergames, in these various healthcare settings. What this might mean not only for future technology design, but also for the conduct of human-centered research is then discussed. We emphasize that designing appropriate assistive technologies for people with dementia requires sustained, empathetic engagement with both people with dementia and their caregivers, grounded in regular, trust-building interactions. Caregivers play a vital role in the appropriation and maintenance of these systems and researchers must be prepared for the emotional demands and relational commitments that such work entails. By embedding technology development within the rhythms of care and prioritizing mutual respect, researchers can create more meaningful, responsive, and sustainable support systems.

The Work to Make Soldiers Work: Civilian Engagement in Support of the Ukrainian Army
S. 1–15, DOI: 10.1145/3772318.3791850
Abstract Links

Since February 2022 the Ukrainian army has been resisting the Russian invasion; this defense would have been less effective without material and logistical support from civil society. While HCI and CSCW have examined ICT in crises, little addresses how civilian–military cooperation is enacted in interstate war and how civilians appropriate commercial technologies into military infrastructures. We report an interview study with observations (N=13) conducted in Lviv during the first five months of the full-scale invasion (Feb–Jul 2022). Our findings show how civilians performed largely invisible work to make soldiers’ work possible: they circumvented broken supply chains, fundraised through digital micro-donation tools, re-engineered commercial drones and software into command-and-control workflows, and joined early cyber and counter-information operations. We contribute to CSCW by theorizing this civilian engagement as wartime infrastructuring and appropriation under extreme risk, and by detailing methodological implications for conducting cooperative-work research in hybrid-war settings.

Differential Benefits: The Impact of Computer Clubs in Palestine on Volunteers
In: Proceedings of the ACM on Human-Computer Interaction, Volume: 10 No.:2, S. CSCW012:1–CSCW012:26, DOI: 10.1145/3788048
Abstract Links

This paper presents a longitudinal case study of two volunteer-led computer clubs in Palestinian refugee camps in the West Bank. Combining participatory action research, autoethnography, and follow-up interviews conducted ten years later, we examine how socio-technical infrastructures of learning were built and sustained under intertwined constraints. While the clubs were designed to support children’s engagement with technology, the most meaningful outcomes were reported by the volunteers, whose roles required navigating logistical, interpersonal, and political challenges in resource-constrained settings. Our findings position volunteers as infrastructural actors: they stitched together tools, partnerships, and routines to stabilize the clubs and create a durable social infrastructure. We identify the breadth of work and social structures implicated in volunteering and show how technology mediates these interdependencies. Recognition and care practices (such as debriefs, reflection rituals, acknowledgments) emerge as design requirements for sustaining participation, reflecting a shift from questions of access to recognition observed in feminist hackerspaces. Gendered trajectories reveal how women volunteers negotiated leadership and gained professional capital in male‑dominated contexts. Our longitudinal findings provide an empirical account of an uneven temporality of impact: durable benefits accrue to those performing infrastructural labor (volunteers), whereas short‑term beneficiaries (child participants) recall little after a decade.

Feeling Guilty Being a c(ai)borg: Navigating the Tensions Between Guilt and Empowerment in AI Use
DOI: 10.48550/arXiv.2506.00094
Schlagwörter: Computer Science - Artificial Intelligence; Computer Science - Human-Computer Interaction; Computer Science - Computers and Society
Abstract Links

This paper explores the emotional, ethical and practical dimensions of integrating Artificial Intelligence (AI) into personal and professional workflows, focusing on the concept of feeling guilty as a 'c(ai)borg' - a human augmented by AI. Inspired by Donna Haraway's Cyborg Manifesto, the study explores how AI challenges traditional notions of creativity, originality and intellectual labour. Using an autoethnographic approach, the authors reflect on their year-long experiences with AI tools, revealing a transition from initial guilt and reluctance to empowerment through skill-building and transparency. Key findings highlight the importance of basic academic skills, advanced AI literacy and honest engagement with AI results. The c(ai)borg vision advocates for a future where AI is openly embraced as a collaborative partner, fostering innovation and equity while addressing issues of access and agency. By reframing guilt as growth, the paper calls for a thoughtful and inclusive approach to AI integration.

Investigating enablers and barriers of health-related assistive technologies: long-term results of sustained use by older adults in urban and rural regions
In: i-com, DOI: 10.1515/icom-2025-0052
Schlagwörter: qualitative research; HCI; older adults; exergame; AHA technology
Abstract Links

Information and communication technology (ICT) support for active and healthy aging (AHA) has risen in prominence over recent years with a goal of facilitating and promoting a self-sustaining lifestyle for older adults. Following a user-centered, participatory, ethnography-based approach, we established a basis for sustained long-term use of ICT for AHA support. Working with two groups of older participants in Germany (aged 61–76 at the outset) over the course of a four-year international project, we facilitated the development of social learning spaces and introduced participants to health-related technologies, exploring enablers as well as barriers to their long-term use. Findings indicate that a mutual interaction between health aspects and social factors was a vital motivator of sustained technology use and that this played a key role in the perceived usefulness of health-related devices. However, this dynamic only emerged over time. Barriers included age-related usability issues and privacy- and data security-based concerns about technology.

Chat with Standards: An Assistant for the Provision of Normative Knowledge for Practical Use in Welding
S. 2171–2188, DOI: 10.1145/3715336.3735798
Abstract Links

Standards form an important basis for the manufacture of high-quality and safe products. As the standards landscape becomes more complex over time, the mandatory interpretation is becoming increasingly challenging and knowledge gained from experience in dealing with the standards plays a key role. This paper uses welding—as a manufacturing process that is highly regulated by standards—to demonstrate the possibilities that large language models (LLMs) offer to assist people and shows how knowledge management can be supported in applying these standards. Therefore, a chatbot prototype specialising in the specific requirements of welding standards was developed and evaluated on the methodological framework of a design case study. The results show that LLMs have the potential to improve access to complex standards beyond simple databases and document searches and facilitate compliance with these requirements. However, there are certain limitations regarding normative language and the need for referencing.

Chatting with Forestry Guidelines: Using Chatbots to Improve Access to Complex Forest Knowledge
In: Proceedings of the 12th International Conference on Communities & Technologies (C&T 2025), DOI: 10.48340/ct2025-1026
Abstract Links

Forestry guidelines play a crucial role in translating environmental policy into actionable practices, yet they are often complex, text-heavy, and difficult for non-experts to navigate. In this paper, we present a prototype called Forea Bot, a conversational AI system developed to address the challenge of accessing forest knowledge. The system uses a retrieval-augmented generation (RAG) architecture. Developed from a socioinformatics perspective, it combines large language models with curated forestry documents and is shaped by participatory design insights. We present findings from an evaluation conducted during a workshop with forestry stakeholders and discuss how such systems shape trust in chatbot responses and make visible tensions between conflicting sources of knowledge in forestry-related communication. While not a substitute for expert consultation, our findings suggest that chatbots like Forea Bot can complement traditional channels of knowledge exchange, particularly in domains characterized by complexity, value pluralism, and limited access to expertise.

Exploring Algorithmic Resistance: Responses to Social Media Censorship in Activism
In: Proc. ACM Hum.-Comput. Interact., Volume: 9 No.:2, S. CSCW072:1–CSCW072:24, DOI: 10.1145/3710970
Abstract Links

Social media platforms have become a double-edged sword for human rights activism, simultaneously offering a stage and facilitating wide-reaching communication and connection, while also imposing censorship through stringent and opaque content governance. This study focuses on the over enforcement of content moderation on social media platforms, affecting activists who tried to engage online publics with issues of forced evictions and displacements in Sheikh Jarrah (SJ) and Silwan, in occupied East Jerusalem in May 2021 --- a critical juncture in the Palestinian-Israeli conflict. By analyzing responses from a survey of 201 users who reported experiencing censorship, and interviews with 14 political influencers and activists, we uncover how these individuals navigate the intricate landscape of social media censorship. The findings reveal a continuum of different ways of responding to censorship, from self-censorship to proactive advocacy of policy change, that highlight the ingenuity activists can employ to bypass content restrictions. This research not only contributes to our understanding of the interaction between social media's technical affordances and activist responses but also discusses broader implications for the design and governance of digital platforms in supporting democratic discourse and human rights activism in conflict zones. This study enriches the ongoing dialogue about social media's dual role as both a facilitator and a controller of public discourse, emphasizing the need for platforms to consider the profound impacts of their technical and policy decisions on global activism.

Between Connection and Control: Technology Appropriation by Older Adults in Iran
S. 188–202, DOI: 10.1145/3742800.3742833
Schlagwörter: nebula
Abstract Links

Although digital technologies offer significant benefits for older adults, including improved communication and reduced social isolation, their effective use is often shaped by broader political, educational, and economic contexts. This study explores how older adults in Iran—aged 62 to 78, with varying literacy levels—appropriate mobile phone technology in their daily lives. Through in-depth interviews, we examine both the perceived benefits and everyday challenges they face. In addition to barriers such as low literacy, unfamiliarity with digital interfaces, and physical limitations, Iranian older adults must navigate a complex landscape of state-imposed digital filtering, surveillance, and VPN-dependent access to basic platforms like WhatsApp. These socio-political constraints exacerbate dependency on family members and further marginalize users with limited literacy. The study highlights the need for culturally and politically responsive design, emphasizing user-centered solutions that account for censorship and digital control in authoritarian regimes. By understanding how older adults negotiate access and meaning in such constrained environments, this research contributes to inclusive technology design and global HCI discourse beyond Western paradigms.

Different Uses of LLM based Digital Health Coaching Devices for Community-Dwelling Older Adults in Europe and Japan - Lessons Learned from an international Research Project
S. 12–27, DOI: 10.1145/3742800.3742851
Schlagwörter: Digital platform; Large Language Models; Social robots
Abstract Links

The e-VITA project represented a collaboration between Europe and Japan, aimed at enhancing Active and Healthy Aging (AHA) through digital coaching solutions. Aging populations present both opportunities and challenges, so e-VITA sought to address these through a virtual coaching system tailored to older adults’ diverse needs. The project integrated artificial intelligence, conversational agents, social robots, and culturally sensitive digital tools to promote autonomy, health literacy, and well-being. Utilising an interdisciplinary approach, the project involved user-centered design, practice-based design in intercultural living labs, and real-life testing across multiple sites in Italy, France, Germany and Japan. A total of 366 participants were reached in three years, 182 of them in Europe and 184 in Japan. The key findings highlighted different preferences between European and Japanese users in terms of interaction styles, which required customization for each region. Personalization and user engagement with the digital coaching systems also played a relevant role. The research further emphasised the need for intuitive technology interfaces, structured training, and ethical considerations regarding data privacy, autonomy, and potential social isolation. The results demonstrated that virtual coaches can improve health management, quality of life, and daily living support. However, challenges such as technical malfunctions, accessibility, and affordability remain barriers to widespread adoption. The participatory approach to technology design in e-VITA shown that such technologies will achieve long-term acceptance and be sustainable only if they are specifically adapted to the actual needs of users. Finally, the intercultural differences illustrate that cultural factors can significantly influence the use of digital assistance systems, making knowledge of these essential for overcoming global challenges through collaborative approaches.

Differences in Human–Avatar Interactions of Older Adults Depend on the Presentation Setting and Health Status of the Participants
In: Proceedings of the 12th International Conference on Communities & Technologies (C&T 2025), DOI: 10.48340/ct2025-1029
Abstract Links

This article examines the interaction between humans and avatars in a long-term care facility. It explores how older people interact with the socially supportive avatar Ann-Sophie in two different situations: individually and in group sessions. Based on qualitative field research, we analyze the differences in communication patterns between residents with and without dementia. Our results show that the dynamics of interaction vary significantly depending on both the social context and cognitive health status. Residents without dementia tended to engage with the avatar in a more goal-oriented manner, while residents with dementia showed more spontaneous and affect-driven reactions. Group settings promoted shared attention and co-present comments, while individual sessions allowed for more focused, personal engagement. By highlighting the interplay between setting, cognitive state, and communicative behavior, we aim to contribute to ongoing discussions in the community about how digital technologies can be embedded in everyday care practice. We argue that understanding such nuanced interaction contexts is essential for designing socially meaningful and inclusive avatar systems in elder care.

Human–Avatar Interaction: Perceptions of Voice and Appearance Among Older Adults in a Residential Care Setting
In: Proceedings of the 12th International Conference on Communities & Technologies (C&T 2025), DOI: 10.48340/ct2025-1028
Abstract Links

This study explores the acceptance and perception of a conversational AI avatar among older adults in a residential care setting. Against the backdrop of increasing interest in human-AI collaboration in health and social care, we developed a photorealistic avatar named Ann-Sophie, designed to support well-being through everyday conversation. The study involved 14 participants across two iterative rounds and employed a mixed-methods approach, combining questionnaires with semi-structured interviews. Results show that perceptions of the avatar’s voice and appearance depend on individual experiences and needs. While some appreciated its lifelike features, others found it emotionally distant. Clarity and responsiveness of the voice, rather than realism, were key to engagement. The study emphasizes the importance of usability and context-sensitive design over mere aesthetics. These findings offer design implications for voice-based AI systems in care settings and call for further exploration of embodied AI in shared human contexts, ensuring that such systems move beyond novelty to sustainable adoption.

Blending Code and Cause: Understanding the Dynamic Motivations of Volunteer Developers in community-driven FOSS projects
S. 1–17, DOI: 10.1145/3706598.3713416
Abstract Links

Understanding the motivations of volunteer developers is crucial for the HCI community as it seeks to design sustainable, community-driven digital platforms. This study explores the dynamics of motivation among volunteer developers in the Foodsharing.de platform, a grassroots movement focused on reducing food waste through community engagement. By investigating the evolving motivations and challenges faced by these developers, our research highlights the unique blend of personal passion, technical skill, and social commitment that sustains their long-term involvement. Through interviews, observations, and participatory research, we uncover how developers balance their commitment to Free and Open Source Software (FOSS) with the platform’s socio-ecological mission. Our findings emphasize the importance of fostering a supportive community, clear governance, and effective infrastructuring to manage motivation, frustration, and expectations. We discuss strategies to enhance volunteer retention, such as improving feedback mechanisms and recognizing contributions, which are critical for the sustainability of volunteer-driven platforms.

Assisting Forests and Trees Planning with a Decision Tree
In: Proceedings of the 12th International Conference on Communities & Technologies (C&T 2025), DOI: 10.48340/ct2025-1024
Abstract Links

Handling uncertainty is tricky, especially when important decisions need to be made. In recent years, forests and forestry have faced increasing pressure from the effects of climate change. Events such as widespread bark beetle infestations have raised new and urgent questions: How should damaged areas be reforested? Which tree species will be resilient in the face of future disturbances and a changing climate? Uncertainty and lack of knowledge can paralyse decision-making, thereby hindering the reforestation process. To explore this issue, an ethnographic study was conducted, combining qualitative interviews, participation in excursions, and observation of the everyday work of forest professionals and forest owners. The goal was twofold: gathering knowledge on the adaptation of forests to climate change and seeing how the design of artefacts could address the issue. Ultimately, a digital tool, called the decision tree, was developed to support the decision-making process. A participatory design process reveled both the potential and the limits of digital tools: While digital tools are capable of supporting and structuring consultation processes, they are far from keeping up with the complexity of specific contexts, such as maintaining landscapes. These findings provide valuable insights into knowledge management and expertise sharing in the fields of Human-computer interaction (HCI) and Computer-supported cooperative work (CSCW).

Wizard of Oz: An Underestimated Method in the Field of Social Robotics
In: Proceedings of the 12th International Conference on Communities & Technologies (C&T 2025), DOI: 10.48340/ct2025-1009
Abstract Links

In 2017, we designed a basic web dashboard to temporarily control Pepper’s robot, which was in the process of implementing an Android remote controller app. Although the intention was to operate the robot’s basic control, its design and function have led to its long-term use of this dashboard, even now. We quite underestimated the potential use of this dashboard. Often, it helps us bring the robot to life and make it functional, whereas the Choregraphe and smartphone remote app could not connect to it. Later, we often used the Wizard of Oz method to impress older adults in the care home and demonstrate the fun aspects of the robot to them. Nowadays, it is less frequent to use the dashboard and Wizard of Oz in general; still, it is a game-changer when new people see and interact with the robot. However, this raises some ethical considerations about manipulating the target groups to like the robot. Therefore, in this paper, we discuss the importance of ethical considerations in using the Wizard of Oz method and the design implications that lead to the long-term use of this dashboard.

“Making Robots Usable”: Empowering Care Professionals to Customize Social Robots in Care
In: International Journal of Social Robotics, DOI: 10.1007/s12369-025-01238-1
Schlagwörter: italg; wineme
Abstract Links

Abstract While robotic systems in eldercare contexts continue to be a popular research topic, they are still not widely used in these settings. We argue that this is partly due to the absence of control and configuration options for end-users. This study reflects on the design of a smartphone app to tailor the use of robots to local needs. We investigated how care workers used the smartphone app to configure and control a Pepper robot to meet the individual needs of the care home’s residents. We developed and tested the app together with 23 participants from four different care facilities over two years. Ultimately, we implemented a feature allowing care workers to program the robot to meet residents’ individual needs without coding. Results indicate that the app enables care workers to provide residents with meaningful interactions with the robot. Our study shows that allowing care workers to control and develop the robot improves its perceived usefulness and overall use of the robot to both care residents and care workers.

Abstract Links

Abstract This paper examines the potential impact of social robots on people with mild cognitive impairments in a nursing home. Within a 4-month design case study, we investigated the practices, attitudes, and social contexts of residents with mild cognitive impairment and their caregivers and designed two prototype apps for a robotic-based system. Subsequently, 10 residents, the former nursing home manager, and one social caregiver participated in a prototype evaluation study for 10 weeks. The goal was to assess group-based user experience and social interactions. Qualitative results indicate that the system can support participants in their individual, social, and daily activities and, therefore, consequently initiate potentially meaningful interactions. One key observation from the video analysis was that the participants initiated unanticipated conversations with the robot, which we discuss regarding the prompting character, design appearance, and affordances of the robot in interaction.

Designing for Resilience: Fostering Ponds of Stability with Computer Clubs in Palestine
S. 1–18, DOI: 10.1145/3706598.3713253
Abstract Links

Addressing the complexities of conflict-affected regions remains a critical challenge for Human-Computer Interaction (HCI). This paper examines the establishment of computer clubs in Palestinian refugee camps, where efforts to create sustainable interventions weighed against the instability of prolonged conflict. To capture this dynamic, we introduce the notion of ‘adaptive ponds of stability,’ which extends the ‘tech public of erosion’ framework [12]. While the latter emphasizes systemic depletion of socio-technical infrastructures, adaptive ponds of stability highlight efforts to foster temporary spaces of resilience. The clubs became hubs of learning, respite, and collaboration—offering moments of routine and empowerment amidst disruption. Reflecting on this, we advocate for a paradigm shift from sustainability to resilience as the primary design goal in unstable contexts. Our findings emphasize adaptability, local agency, and cultural sensitivity that respond dynamically to context-specific challenges, offering a nuanced approach to advancing HCI interventions in conflict-affected settings.

Forced Trust and Digital Control in a Global Health Crisis: The Case of a Marginalized Community in Iran’s Kermanshah Province
S. 71–95, DOI: 10.1145/3744169.3744177
Schlagwörter: crosscom
Abstract Links

Computing technologies can function both as instruments for public health management and mechanisms for political control. This study investigates the deployment of Information and Communication Technologies (ICTs) in Iran’s response to the COVID-19 pandemic, with a particular emphasis on Kurdish communities in Kermanshah province, a historically marginalized group. Through 22 interviews, we explore how state-controlled digital infrastructures influenced citizen engagement with pandemic-related ICT services. Although government-developed tracing applications, information platforms, and digital health services were ostensibly designed to manage the crisis, they also facilitated mass surveillance, imposed restrictions on mobility, and suppressed alternative narratives. A crisis of trust prompted citizens to adopt alternative strategies, such as encrypted messaging, informal information networks, and social media. By illustrating how trust, mistrust, and digital infrastructures are co-constructed in crisis contexts, this paper contributes to critical computing research by raising significant questions about governance, design, and ethics during times of uncertainty.

Abstract Links

This paper presents the results of a long-term exploratory study that examined the social and emotional impact of using a social robot with a variety of applications to promote activities for people with advanced dementia and their caregivers. Qualitative data was collected over 10-months in a secured care environment in which we explored the appropriation of a social robot by 23 participants, including 13 PwAD, their family members, and professional caregivers. Our findings indicate that the use of the social robot demonstrated the potential to improve well-being, engagement, and social interaction of PwAD, even demonstrating the ability to create new memories and experiences. We discuss requirements and challenges in integrating social robots into secured care environments to provide a nuanced understanding for future research aiming for appropriate and inclusive care outcomes and socially embedded innovations that address the social actors involved and thus contribute to practical solutions for professional care.

Towards a 4-Day Week in Hospital Care: Exploring Staff Perspectives and the Role of Technology in a Local German Hospital
S. 278–291, DOI: 10.1145/3742800.3742832
Schlagwörter: italg
Abstract Links

The healthcare sector faces growing challenges in ensuring staff satisfaction and retention while maintaining high standards of patient care. One proposed solution is the introduction of a four-day workweek (4DW). This preliminary study investigates the organizational, technological, and experiential conditions under which a 4DW could be accepted and implemented in a hospital setting. The study was conducted in a semi-rural German hospital and is based on a participatory health research approach. Data were collected through observations, informal conversations, and semi-structured interviews with medical and nursing staff. Particular attention was given to workflow inefficiencies, hierarchical communication barriers, and the role of digitalization in relieving administrative workload. The findings indicate that a 4DW has the potential to improve job satisfaction and staff retention. However, successful implementation depends on structural readiness, participatory decision-making, and technological support. Digital tools, such as process automation and electronic documentation, can contribute to workflow optimization, but their effectiveness is shaped by organizational culture and employee acceptance.

Supporting Healthcare Workflows with Smart Glasses: Insights from a Participatory Design Study on Post-Stroke Patient Positioning
In: Proceedings of the 23rd EUSSET Conference on Computer Supported Cooperative Work, DOI: 10.48340/ecscw2025_cp03
Abstract Links

The shortage of healthcare practitioners in developed countries, combined with insufficient digital infrastructures and limited digital teaching opportunities in healthcare training, affects both patient care quality and the well-being of healthcare workers. To address this, innovative technologies have emerged to support professionals in learning complex interventions while alleviating workload pressures. This study focuses on smart glasses as a digital assistive learning tool in healthcare training. We conducted a study with 52 healthcare practitioners who used smart glasses to assist in patient positioning by following a predefined workflow based on the Bobath Concept. Through observations, interviews, and usability testing, we evaluated the system’s impact on learning experiences, workflow integration, and workload. Our findings suggest that smart glasses enhance learning and workflow integration, with variations in workload perception based on experience levels. However, several challenges remain, including issues with voice recognition, image quality, and maintaining focus on the patient. This research contributes to the ongoing discourse by providing recommendations for optimizing smart glasses in healthcare education and practice, emphasizing their role in bridging training gaps, supporting healthcare workflows, and enhancing the point of care experience.

Personalization by Design: A Case Study on CardaFit’s Appropriation in Workplace Settings
In: Proceedings of the 12th International Conference on Communities & Technologies (C&T 2025), DOI: 10.48340/ct2025-1034
Abstract Links

This paper presents an appropriation study of CardaFit, a cross-platform mobile application designed to mitigate the negative health effects of prolonged sitting among desk workers. The app promotes micro-interventions through brief, repeated health reminders that encourage hydration, movement, physical activity, and regular breaks during work hours. CardaFit integrates practice-centered design with personalized notifications, gamification elements, and meal recommendations. The system emphasizes tailorability, user control, and motivational feedback mechanisms, while incorporating context-sensitive nudging to support behavioral change. This demo contributes to the understanding of design principles and features grounded in user feedback, enhancing both relevance and usability, and paving the way for AI-driven personalization, user autonomy, and privacy-aware interactions. Through a longitudinal study, we demonstrate the viability of CardaFit as a realistic and accessible solution for fostering sustainable wellness behaviors in technology-mediated work environments.

Prototyping Industry 4.0: Tracing Infrastructural Resonance in a Smart Factory Demo
In: Proceedings of the 12th International Conference on Communities & Technologies (C&T 2025), DOI: 10.48340/ct2025-1008
Abstract Links

With the advent of Industry 4.0, Internet-of-things, and data-centric technologies, the concept of the smart factory (automation of the factory) has gained traction to make machines more than mechanical artifacts. It creates an ecosystem of technologies providing infrastructure to embed technological advancements with the emerging needs of the system. However, with the increasing demand for automation, several socio-technical challenges pertain due to the infusion of several infrastructural layers in the smart factory settings. We present “Demo Smart Factory”, which automates a logistic pipeline, including dummy manufacturing, quality assurance, and sorting, and provides control mechanisms on the real-time sensor data based on components and units of the factory to different stakeholders via a digital twin. Through this exemplary use-case of a logistics smart factory demo, we aim to illustrate the resonance between different infrastructural layers and highlight key socio-technical factors that shape the design and implementation of smart factory systems. We also identify key pitfalls that need to be avoided or balanced in realizing large-scale and multi-layered interventions like a smart factory.

Abstract Links

The COVID-19 pandemic triggered an unprecedented shift from office-based to remote work, catching many organizations off guard. This paper examines a German video game development company's adaptation to enforced working from home during the first lockdown. Through remote interviews with 20 employees from various departments, we identify technological, physical, organizational, and socio-psychological challenges. To address these, we devised a Crisis-Responsive Infrastructuring framework, blending socio-technical perspectives with strategies to enhance organizational adaptability. Our research highlights the crucial and reassuring role of Information and Communication Technology in maintaining productivity and social connectivity and reshaping work dynamics and infrastructure. Further, we emphasize the importance of flexible work concepts, such as hybrid models and decentralized organizations, in fostering resilience. Finally, by advocating for adaptive infrastructures that support remote work during crises and beyond, we aim to enrich the discourse on modern work practices and offer a systematic approach to strengthening organizational resilience.

Abstract This paper explores technical implications and design opportunities that are conceptualized to inform a socio-robotic system with digital applications to support the recovery process of patients within a rehabilitation facility. By conducting observations and interviews with patients and therapists, we identified key challenges and design opportunities in a specific orthopaedic rehabilitation context and process. The findings indicate the design potentials of a socio-robotic system to enhance patient engagement and recovery by providing personalized activities, a meaningful interaction and a motivating surrounding by using music-based exercises. Our research suggests that integrating digital applications with robotic systems may be used in the long-run to offer tailored exercises, stimulating concepts to motivate and maintain patients in therapy process, real-time feedback, and data-driven progress tracking, thereby improving the overall therapeutic outcomes. By addressing these factors, our proposed socio-robotic system aims to create a more interactive and engaging orthopaedic rehabilitation experience and environment, ultimately supporting patient recovery and improving overall treatment.

Cultivating Care: Designing Civic Technologies with Citizens and Governments for Urban Green Maintenance
S. 63–80, DOI: 10.1145/3742800.3742845
Abstract Links

Urban green spaces (UGS) are vital for biodiversity and urban quality of life, but face challenges from climate and limited municipal resources. This study investigates how civic engagement can support the maintenance of UGS as well as the role of digital participation tools, such as gamification, augmented reality (AR) and sensor-based feedback, in promoting engagement in smart cities. Through interviews with citizens and administrative officials in six German cities, along with a participatory design workshop, the study surfaces key tensions between informal citizen-led efforts and formal governance structures. While many citizens are willing to contribute to UGS care, they are often hindered by bureaucratic hurdles and unclear responsibilities. Administrations, although supportive of civic participation, frequently lack the capacity to coordinate or sustain it. Our findings reveal that digital technologies hold potential to support long-term participation if embedded in hybrid governance models that align with technological interventions, institutional processes and community practices. This study contributes to HCI and Digital Civics by highlighting administrative constraints even in digitally progressive municipalities, advocating for hybrid approaches combining digital participation platforms with grassroots engagement and institutional flexibility, and discussing the ethics of persuasive design in participatory processes. Through a grounded digital participation concept, we illustrate that civic technologies, when reimagined as mediators of collective care and trust, are crucial for creating sustainable and inclusive urban green infrastructure.

Abstract Links

In today’s global conflicts, the impact of social media and information and communication technologies (ICT) is undeniable. These platforms have been instrumental in events such as the uprising in Tunisia, the protracted war in Syria, the advocacy of Palestinian activists, the Ukraine-Russia conflict, and the confrontation between Colombian guerrillas (FARC-EP) and the Colombian army. This chapter provides a comprehensive insight into the contemporary use of ICT, especially social media, in these conflicts. We look at the strategies and methods used by different groups, highlighting their adaptation of these digital tools under conditions of the threat of online surveillance, potential legal repercussions and fluctuating levels of connectivity. We emphasise the need for an in-depth perspective on the use of ICTs in conflict in order to truly understand these nuanced appropriation practices.

From Singularity to PlurAIverse: Expanding the AI Design Paradigm
S. 1–3, DOI: 10.1145/3686169.3686207
Abstract Links

At a time when Artificial Intelligence (AI) is rapidly transforming human life, it is crucial to ensure that its development is consistent with ethical standards and humanistic values. This paper aims to initiate a dialogue on the adoption of a pluralistic design approach to AI, called the PlurAIverse. Inspired by Arturo Escobar’s ’Designs for the Pluriverse’, this work proposes design principles that emphasise inclusivity, cultural sensitivity and social justice in AI development, and calls for a more equitable approach to AI governance that balances technological progress with broader societal welfare. The paper highlights the current dominance of large technology corporations in the AI landscape, driven by profit motives that are often at odds with ethical considerations and the diverse needs of global communities. This work does not claim to provide definitive answers, but aims to facilitate a collective effort to create momentum that emphasises the importance of incorporating diverse design approaches into AI development. In doing so, we can counter the dominant tech-centric narratives and ensure that AI technologies reflect and respect the pluralistic nature of our global society. The ultimate goal is to promote AI systems that are technologically advanced, ethically sound and socially inclusive, marking a significant shift towards a more just and humane technological future.

Gender and Technology at Work: From Workplace Studies to Social Justice in Design
S. 405
Schlagwörter: Computers / Social Aspects; Political Science / Labor & Industrial Relations
Abstract

This book brings together the vast research literature about gender and technology to help designers understand what a gender perspective and a focus on intersectionality can contribute to designing information technology systems and artifacts, and to assist organizations as they work to develop work cultures that are supportive of women and marginalized genders and people. Drawing on empirical and analytical studies of women's work and technology in many parts of the world, the book addresses how to make invisible aspects of work visible; how to recognize women's skills without falling into the trap of gender stereotyping; how to engage in improving working conditions; and how to defend care of life situations and needs against a managerial logic. It addresses challenges for design, including many overlooked and undervalued aspects, such as the complexities involved in human-machine interactions, as well as the need to create safe spaces for research subjects.

Schlagwörter: accountability; activism; algorithm bias; bias; fairness; Palestine; Sheikh Jarrah; social media; transparency
Abstract Links

Social media technologies have been empowering to some human rights activists, providing a platform for exercising free speech and mobilization. However, many activists have voiced concerns and shared experiences they understand as considerable censorship on these platforms, under the guise of content governance. In an effort to increase the understanding and transparency of content moderation practices during conflicts, this study investigates the perceived reasons for censorship as understood by activists and the explanations made visible to activists by social media platforms, if any were given. Our case study to examine these platforms-activists relations is the events which occurred in May 2021 in East Jerusalem's Sheikh Jarrah neighborhood, which was a significant moment in the Israeli-Palestinian conflict and garnered international attention. The over enforcement of content moderation faced by Palestinians and their allies during these events on social media raised concerns about freedom of speech and the role of technology in activism. Our study deepens understanding through findings from a survey of 201 social media users who reported potentially unfair moderation decisions, and from 12 interviews with political influencers to grasp the broader implications of content moderation on activism. The findings of this study indicate a substantial disparity between the official explanations made visible to the activists by the social media platforms, and the reasons as perceived by users. This has significant implications, both socially and for social media platforms -- as CSCW and Group work environments --- on activist groups and the potentialities of democratic discourse. This study serves as an important contribution to the debate on the role of social media content moderation in human rights activism, particularly in conflict zones.

Utopian Design Space: Practical Concerns and Transformative Ambitions
In: Interacting with Computers, S. iwae055, DOI: 10.1093/iwc/iwae055
Abstract Links

Interconnected global crises have emphasized the need for alternative visions of the future, making transformative action urgent. Consequently, Sustainable Human–Computer Interaction (SHCI) has seen growing interest in exploring means to support radical and sustainable change, starting with grassroots, community-driven endeavors. This study explores the concept of Utopian Design Space (UDS) in the context of surplus redistribution in grassroots communities. The objective is to understand how practical concerns and transformative ambitions intersect, creating spaces that foster sharing and caring practices. Through action-oriented research, we examine six local projects, highlighting ICT’s role in these initiatives. Our findings highlight the challenges and opportunities in managing values, scalability, sustainability and inclusivity within UDSs. We discuss how aligning ICT with community practices can foster socio-technical innovation and support transformative change, introducing the notion of prefigurative technology. These insights can help us envisage design spaces that foster utopian ideas like equitable resource distribution and generalized reciprocity.

Abstract Links

HCI and CSCW have a long-standing interest in the consequences of digital transformation for work practices. A key part of this is its impact on labour relations. While prior HCI studies have examined labour relations in domains such as platform work, few have looked at industrial settings. This paper presents an ethnographic study of works councils in Small and Medium-sized Enterprises (SMEs) in Germany. Works councils exemplify the principle of Co-Determination, which is the right of employees to participate in the design and management of their workplace and play a vital role in vetting new technologies whenever they imply changes in work practices. A number of issues confront works councils when they attempt to accomplish this, namely a lack of time, knowledge, and external support. We discuss these issues and consider their implications for both design and the constitution of workplace democracy in future industrial settings.

Abstract Links

Since 2014, Botswana's Okavango Delta has been declared a UNESCO World Heritage site. One effect has been to parse the conservation area from human settlements, thus aggravating the conflict between local cattle farmers and predatory animals, particularly lions. In response, the LionAlert system, launched together with CLAWS Conservancy, is warning farmers of lions passing invisible digital geofences and thus helps prevent attacks on cattle as well as the poaching of the endangered predators. Because technology needs to be embedded in a larger, holistic view of the conflict parties’ practices, needs and abilities, we apply the Matristic Design approach focusing on cooperation on the ground which bears matriarchal roots. Here, we outline how we implemented this approach in the LionAlert project, while building a tech-based alert system to mitigate Human-Wildlife-Conflict (HWC), and what can be done to further enhance human-wildlife coexistence: access to technology, education, and support of traditional farming practices.

In Between Users and Developers: Serendipitous Connections and Intermediaries in Volunteer-Driven Open-Source Software Development
S. 1–15, DOI: 10.1145/3613904.3642541
Schlagwörter: Grassroots community; Intermediary; Open-Source Software; Sustainability
Abstract Links

Technology plays a pivotal role in driving transformation through grassroots movements, which operate on a local scale while embracing a global perspective on sustainability. Consequently, research emerged within Sustainable HCI, aiming to derive design principles that can empower these movements to scale their impact. However, a notable gap exists in contributions when addressing scalability of large free and open-source software (FOSS) projects. This paper aims to present our endeavors as action-oriented researchers with the voluntary-driven Foodsharing.de movement, focusing on a local community, the open-source developers and their connections. Within a community of 585,000 users and only a few developers that is dedicated to save and share surplus food, we explore the concepts of ‘intermediary experience’. We also introduce the notion of ‘serendipitous connections’, highlighting the unintentional yet beneficial associations that can arise from the collaboration between developers and users.

Knowledge Spillover: Between Serendipity and Strategic Planning - Lessons for Practice-oriented Interventions into Regional Innovation Systems
In: Proceedings of the ACM on Human-Computer Interaction, Volume: 8 No.:CSCW1, S. 1-26, DOI: 10.1145/3637363
Abstract Links

Previous CSCW research has paid increasing attention to regional innovation systems providing the context for CSCW research and design. In this paper we provide insights into attempts to intervene in such a regional innovation system via practice-oriented activities. Our findings describe experiences of co-creating knowledge around digitization of SMEs on a regional level, beyond individual company contexts. We reflect on the benefits and challenges such an approach affords and highlight the importance of interpersonal relationships and similarities between practices in different contexts to enable intended but also initially unexpected knowledge spillovers. Our findings highlight how a praxeological approach to CSCW can be influential in regional development programs, and open this field to CSCW research and design. We draw out lessons for similar interventions and outline fruitful avenues for future research.

Abstract Links

This SIG delves into the multifaceted dynamics of conducting ethnographic research in volatile environments marked by political unrest, conflict, economic or natural disasters. Our aim is to start nuanced discussions to critically examine the ethical, methodological, and psychological challenges of conducting research in these environments. We discuss the adaptation of ethnographic methods to prioritize safety for participants and researchers, emphasizing ethical and moral considerations in unstable environments. We will explore the impact of researchers’ presence in sensitive environments, focusing on establishing relationships, understanding, and respecting local customs, and minimizing disturbance to the community. Moreover, we address the emotional burden borne by both researchers and participants, sharing strategies for building resilience and managing secondary trauma. Using real-life case studies, this SIG aims to provide an in-depth exploration of the practical challenges and ethical dilemmas, sharing insightful lessons and valuable perspectives to ethnographers, enhancing their approach to research in such demanding contexts.

Prototyping and Evaluating Bo App: A brain measurement device as a feedback tool for cognitive training
In: OzCHI2024
Abstract Links

Each year, the number of older adults with mild cognitive impairment (MCI) increases; their aging process negatively impacts their subjective and emotional well-being and quality of life. Artifacts from the digital world could play a significant role in preventing or reversing MCI. This study developed a smartphone application prototype, known as the Bo app, that utilizes a Functional Near-Infrared Spectroscopy (fNIRs) sensor to provide biofeedback during cognitive interventions. The goal was to coach older adults to conduct unsupervised and regular cognitive training sessions at home. It was found that designing minimalist apps kept users focused, while various feedback mechanisms, such as real-time biofeedback, daily feedback, monthly feedback, and competitive feedback, encouraged regular cognitive training sessions. The participatory design approach enabled users to benefit from smartphone applications tailored to their preferences, expectations, and needs, encouraging them to be more productive and creative.

Nurturing Digitally Mediated Post-Growth Work Economies
S. 121–124, DOI: 10.1145/3678884.3689136
Abstract Links

Within Computer-Supported Cooperative Work (CSCW), efforts to digitalize work contribute to continual economic growth by, e.g., enhancing work productivity and mediating workflows of capitalist firms to accumulate more and evermore capital at the expense of the marginalization of workers who are pushed to the margins, rendering their work poorly compensated and undervaluing essential care and reproductive work. Extending the growing call to move beyond growth politics and toward post-growth, this panel brings researchers, designers, and practitioners together to engage in a critical dialogue on how CSCW and HCI principles can be adjusted and harnessed to cultivate futures to enhance human and ecological wellbeing rather than perpetuating unsustainable growth, where work does not fuel endless consumption but meet human needs and nurture sustainable livelihoods. This panel aims to nurture the Post-growth HCI Collective to work together, in solidarity, to resist the commodification and drive for infinite capital accumulation in/through digital technologies for the betterment of CSCW, HCI, and the broader computing community.

Impacts vs Implications: Rushed Technology Adoption in Small and Medium Enterprises due to Covid-19 Pandemic
In: Proceedings of 22nd European Conference on Computer-Supported Cooperative Work, DOI: 10.48340/ecscw2024_n07
Abstract Links

The surge of digitalization during the pandemic has long-lasting impacts on business organizations: small and medium enterprises (SMEs) rushed towards digitalization to continue operations with the ever-changing local and international implications of the pandemic. This caused these businesses to adopt digital technologies for work and interconnection, often overlooking the necessary use innovations and skills required for long-term usage, with the aim of becoming agile and resilient against the pandemic. To understand the long-term impacts and implications of rushed technology adoption in SMEs, we used case-oriented qualitative comparative analysis (QCA) and content analysis over a collection of thirty semi-structured interviews with SMEs based in Germany. The preliminary findings of our long-term study reveal the haphazard and impulsive decision making in SMEs, rushing towards digitalization to be resilient and agile to the changing work conditions which led to a high demand for technology-related skillset in employees. Through this study we contribute to the understanding of technology adoption, use and appropriation for work in SMEs elaborating the necessity for long-term processual nature which is similar to notion of infrastructuring.

Development and Evaluation of a Knowledge-Based Cyber-Physical Production System to Support Industrial Set-Up Processes Considering Ergonomic and User-Centered Aspects
S. 317-329, DOI: 10.1007/978-3-031-35741-1_24
Schlagwörter: Augmented Reality; Cyber-Physical Production System; Industrial Set-Up
Abstract

Dynamic markets and constantly changing work practices are causing an increased number of industrial set-up operations on production machines in the wake of a growing demand for customized product requirements. Augmented reality (AR)-based cyber-physical production systems (CPPS) can be used to support complex and knowledge-intensive processes. Resting on a comprehensive ethnographic study, this topic was addressed to identify practices of machine operators in the course of set-up processes on forming or bending machines through a qualitative research approach. Subsequently, a set-up application for an AR-mediated head-mounted display was developed according to a user-centered design approach. For a holistic, objective and subject-related human factors analysis on the handling of AR-based CPPS in the context of assembly or set-up processes, ergonomic sub-studies were conducted. The research work advances the state of the art in the design of digital technologies or CPPS to support operators who are entrusted with set-up processes of industrial production machines.

(Re-)Distributional Food Justice: Negotiating conflicting views of fairness within a local grassroots community
S. 1–16, DOI: 10.1145/3544548.3581527
Abstract Links

Sustainable HCI and Human-Food-Interaction research have developing interest in preventing food waste through food sharing. Sustainability requires attention to both the opportunities and challenges associated with the building of food sharing groups engaged in the redistribution of food but also in developing a wider agenda which includes, for instance, the local production of food resources. In this paper, we argue for a better understanding of the different conceptions of ‘fairness’ which inform volunteer and guest practice and in turn mediate community-building efforts. We examine the practices surrounding ‘SharingEvent’ and challenges faced to sustainability by the heterogenous, and sometimes contested, commitments of the people involved. We further consider how ICT provided opportunities for explicit examination of ideological differences concerning what ‘sharing’ might mean. Our findings show that community building is dependent on the negotiation of different values and purposes identified. We derive recommendations for action-oriented researchers ultimately concerned with systemic transformation.

From Surplus and Scarcity toward Abundance: Understanding the Use of ICT in Food Resource Sharing Practices
In: ACM Transactions on Computer-Human Interaction, Volume: 30 No.:5, S. 80:1–80:31, DOI: 10.1145/3589957
Schlagwörter: abundance; Abundance; grassroots; Grassroots; HFI; sharing economy; Sharing Economy; surplus; Surplus; Sustainability; sustainable HCI; Sustainable HCI
Abstract Links

Food practices have become an important context for questions around sustainability. Within HCI, sustainable HCI and human-food-interaction have developed as a response. We argue, nevertheless, that food practices as a social activity remain relatively under-examined, and further that sustainable food practices hinge on communal activity. We present the results of action-oriented research with a grassroots movement committed to sustainable food practices at a local, communal level, thereby demonstrating the role of ICT in making food resource sharing a viable practice. We suggest that the current focus on food sharing might usefully be supplemented by attention to food resource sharing, an approach that aligns with a paradigm shift from surplus to abundance. We argue for a design that aims to encourage food resource sharing at a local level but that also has wider ramifications. These “glocal” endeavors recognize the complexity of prosumption practices and foster aspirations for “deep change” in food systems.

Articulation Work and the Management of Intersubjectivity Disjunctures in Offshored Production

Schlagwörter: articulation work; ethnography; German-Chinese collaboration; HQ-subsidiary interaction; industrial production; intersubjectivity; offshoring; SME
Abstract Links

Since the move away from integrated value chains in production in the 1980s, the outsourcing and offshoring of various aspects of manufacturing has become commonplace. This has led to global production and marketing relationships between enterprises in numerous different countries, a prominent axis being between Europe and Asia. This paper reports on a study of one such offshoring relationship between a German SME (Small and Medium Enterprise) and their Chinese subsidiary, the trials and tribulations of the collaboration between them, and the implications of this for our understanding of how articulation work might be best supported in the context of global production. We also look at how a separate entity, which we term an 'articulation hub', was established to support articulation between the sites. While a number of studies have looked at articulation work in Global Software Development (GSD), there are very few ethnographic studies of offshored manufacturing, despite the unique challenges it presents. We find here that issues arise not only because of differences in technology environments, infrastructures, and cultural expectations, but also because of differing development strategies and business philosophies. The core problem confronting articulation work in offshored production is the difficulty of arriving at a mutually-grounded intersubjectivity, where shared assumptions about working practices and their relative importance and value can be trusted to apply, leading to what we term 'intersubjectivity disjunctures'. These disjunctures have a number of important implications for accomplishing articulation work. This paper offers a number of contributions to CSCW. First, it adds to a very thin corpus of CSCW-relevant ethnographic studies of global manufacturing. Second, it finds that articulation work in offshored production is less closely-coupled than it is in other distributed settings, making conventionally promoted solutions, such as knowledge sharing and relationship building, less relevant. Third, it reveals how differences in moral reasoning can result in different sites assigning very different priorities to articulation work. Finally, while articulation work is typically seen to be invisible work in CSCW, we argue that, in this context, there are a number of ways in which using a separate hub to actively render articulation work visible may be the best solution.

Investigating the Potential and Impacts of Social Robots to Engage People with Advanced Dementia and their Caregivers: Early Insights from an Exploratory Ethnographic Study within a Protected Care Environment
S. 272–278, DOI: 10.1145/3594806.3594826
Schlagwörter: care facility; people living with advanced dementia; protected care environment
Abstract Links

This paper presents the outcomes of an exploratory study that examined the social impact of a social robot with a suite of different robotic-based exergames for people with dementia and their caregivers. Qualitative data was collected over a period of two months, during which time we explored the daily life of 12 people with advanced dementia and their social and professional caregivers. We focus on the experiential aspects of the system and examine its social impact when integrated into the daily routines of both people with dementia themselves and their care-ecosystem. Our findings indicate that the use of social robots could provide a socio-emotional value for people living with advanced dementia in terms of variety and engagement in meaningful and playful activities. Results suggest that the system enhanced social-interaction, invigorated relationships, and improved the empowerment of people with dementia and their caregivers to face daily challenges.

Rurality and Tourism in Transition: How Digitalization Transforms the Character and Landscape of the Tourist Economy in Rural Morocco
Abstract Links

The character of rural Morocco is changing due to increasing tourism and social media usage. This paper outlines the different consequences of ICT usage among people working in the tourism sector as part of the transitional economy in a remote area. In this region, tourism has grown into one major income sources for a few valley inhabitants – mostly men with a school education, digital and language skills, and who are financially stable. As this transitional economy evolves alongside digitalization and ICT usage and therefore a change of the region’s rural character, it leads to challenges and concerns for the local population. This ethnographic study analyzes the interdependence of increasing tourism through digitalization and the notion of rurality as a resource from a sociotechnical perspective.

Re-articulating North-South Collaborations in HCI
S. 1–4, DOI: 10.1145/3544549.3583752
Abstract Links

Research connecting the ‘Global South’ and ‘Global North’ is not new to HCI. However, over the last few years we have seen a prominent shift in the ways we understand, represent and engage in North-South collaborations. Central to these discussions is the need to re-frame the nature of collaboration between and across geographies in which power dynamics, coloniality and the handling of differences are at the fore. In this panel, we will discuss experiences of HCI collaboration across the ‘Global South’ and ‘Global North’. The panel will unpack the joys, fluidity and tensions within such collaborations from various geographical perspectives, in an effort to de-homogenize the Global South, and provide ways forward for an HCI flavored re-articulation of collaboration across geo-politically established and epistemic borders.

Designing for Health, Engagement and Social-Interaction: A Multimodal and AR-based Sport System to facilitate digital Connectedness over Distances
DOI: 10.48340/ihc2023_p007
Abstract

This work presents a prototype for a multimodal and augmented-reality (AR) based system designed to facilitate individual and social activities, promote health and well-being and support participation for various people. A practice-based design and research approach was used to explore requirements, to conceptualize, design and develop AR-based activities for a multimodal interaction. We have interviewed members from seven different sports associations and conducted design workshops to understand how to design AR-applications to promote an active lifestyle and at the same time to build a bridge for new sustainable societies and active communities. The prototype and approach presented here will serve to discuss and reflect future research activities, methodological concepts, and experiences in the field of HCI, sports, and AR.

Addressing Values in Co-Design Projects: Lessons Learned From Two Case Studies in Sensitive Contexts
In: Interacting with Computers, DOI: 10.1093/iwc/iwac024
Abstract Links

Human–computer interaction (HCI) scholars and others have advocated treating design as inevitably implicating political and ethical sensitivities. A subset of those considerations has been the attempt to deal with the often conflicting interests of stakeholders through ‘value sensitivity’. Drawing on value-sensitive design (VSD) as an inspiration, we emphasize the necessary way in which the evolving contextuality of the values in question shaped our research collaborations. This paper presents a retrospective analysis of two case studies from long-term user-centered design projects in fields with explicit ambitions for value-driven HCI research and concerned with emancipation and empowerment. The first, a 3-year project, entailed an explicit commitment to feminist policy initiatives with female participants that aimed at fostering values of gender equality. The second, a 4-year project, dealt with HCI research with and for older adults, where a multimodal mobility platform for ridesharing and public transportation was developed. We show how we translated general commitment into pragmatic, co-design research goals and infrastructures. The long-term ambition of our endeavors and integration of a broad stakeholder base were vital to support this. We additionally provide insights into how our approach offered safe spaces for trustful collaboration and flexibility when adapting methods to specific contexts.

Abstract Links

Intercultural studies are scarce but yet insightful to better understand reactions of older adults to human-like Android robot behavior. They help to see which reactions of participants are universal and which are country specific. Research with android robots and older adults has many results that are based on online research with pictures or on research that has been carried out in labs in one country. Within a Japanese-European research project, we had the rare occasion to work with an android robot in both countries and compare the results. We collected data from 19 participants that were invited in a Living Lab at two universities in Japan and Germany. The data contains interviews, videos and questionnaires and was analyzed with a mixed method approach. Results indicate that the android robots of this study are not in the valley of the uncanny valley theory. We could observe that the older adults and stakeholders from both countries were open to talk to the robot, some even about private topics, while others preferred to use the robot to retrieve information. German participants wished for more gestures, while Japanese participants were keen on the relatively little number of gestures. With this work we contribute to a broader understanding on how older adults perceive android robots and could show that an android robot with its human-like appearance is not seen as uncanny.

Abstract Links

Research on social robots in care has often focused on either the care recipients or the technology itself, neglecting the care workers who, in and through their collaborative and coordinative practices, will need to work with the robots. To better understand these interactions with a social robot (Pepper), we undertook a 3 month long-term study within a care home to gain empirical insights into the way the robot was used. We observed how care workers learned to use the device, applied it to their daily work life, and encountered obstacles. Our findings show that the care workers used the robot regularly (1:07 hours/day) mostly in one-to-one interactions with residents. While the robot had a limited effect on reducing the workload of care workers, it had other positive effects, demonstrating the potential to enhance the quality of care.

Nationalizing the Internet to Break a Protest Movement: Internet Shutdown and Counter-Appropriation in Iran of Late 2019

Abstract Links

To deal with a spontaneous civil uprising following a substantial rise in gas prices, the Iranian security apparatus imposed in late 2019 techno-political measures and blocked access to international websites and services. To analyze these measures, we conducted 19 interviews with Iranians living inside and outside the country. We argue that the concept of the shutdown, as portrayed in Western media, is not perfectly suitable to describe the infrastructural restrictions and propose the concept of an internet nationalization. This paper offers an in-depth analysis of what the nationalization meant and how it affected the lives of Iranians participating or not participating in the protests. We also report on a variety of creative measures, both technical and non-technical, Iranians took to counter-appropriate the government-imposed shutdown of international connectivity. Based on these data, we elaborate on the concept of counter-appropriation.

Zoomorphic Robots and People with Disabilities
S. 5, DOI: 10.1145/3543758.3547552
Abstract Links

Although zoomorphic robots are already popular as companions in some parts of the world, like Japan, they are still a niche product in Germany and are primarily present in academia. In this study, we analyse the effects of the new version of the zoomorphic robot AIBO on people with disabilities living in residential care homes. We observed the interaction for four weeks, giving the care workers and residents complete control of the robot. We specifically looked at factors like well-being and interaction strategies. Our findings show mixed results. Whereas AIBO seems to have positive effects on some residents, e.g. reducing loneliness and enhancing personal well-being, others relate less positively to its limited functions and language restrictions. This study indicates that AIBO has the potential to be used meaningfully in real-world care contexts in Germany but needs improvement to have a fully positive impact.

RetrofittAR: Supporting Hardware-Centered Expertise Sharing in Manufacturing Settings through Augmented Reality
In: Computer Supported Cooperative Work (CSCW), DOI: 10.1007/s10606-022-09430-x
Schlagwörter: Augmented Reality; CSCW; Manufacturing; Expertise Sharing; Retrofit
Abstract Links

Since almost the onset of computer-supported cooperative work (CSCW), the community has been concerned with how expertise sharing can be supported in different settings. Here, the complex handling of machines based on experience and knowledge is increasingly becoming a challenge. In our study, we investigated expertise sharing in a medium-sized manufacturing company in an effort to support the fostering of hardware-based expertise sharing by using augmented reality (AR) to ‘retrofit’ machines. We, therefore, conducted a preliminary empirical study to understand how expertise is shared in practice and what current support is available. Based on the findings, we derived design challenges and implications for the design of AR systems in manufacturing settings. The main challenges, we found, had to do with existing socio-technical infrastructure and the contextual nature of expertise. We implemented a HoloLens application called RetrofittAR that supports learning on the production machine during actual use. We evaluated the system during the company’s actual production process. The results show which data types are necessary to support expertise sharing and how our design supports the retrofitting of old machines. We contribute to the current state of research in two ways. First, we present the knowledge-intensive practice of operating older production machines through novel AR interfaces. Second, we outline how retrofitting measures with new visualisation technologies can support knowledge-intensive production processes.

Producing and Consuming Instructional Material in Manufacturing Contexts: Evaluation of an AR-based Cyber-Physical Production System for Supporting Knowledge and Expertise Sharing
In: Proceedings of the ACM on Human-Computer Interaction, Volume: 6 No.:CSCW2, S. 366:1–366:36, DOI: 10.1145/3555091
Schlagwörter: augmented reality; cyber-physical production systems; evaluation; knowledge and expertise sharing; machine set-up; manufacturing contexts
Abstract Links

Fast-paced knowledge and expertise sharing (KES) is a typical demand in contemporary workplaces due to dynamic markets and ever-changing work practices. Past and current computer supported cooperative work (CSCW) research has long been investigating how computer technologies can support people with KES. Recent claims have asserted that augmented reality- (AR-)based cyber-physical production systems (CPPS) are poised to bring significant changes in the ways that KES unfolds in manufacturing contexts. This paper scrutinises such claims by implementing a short-term evaluation of an AR-based CPPS and assessing how it can potentially support (1) the generation of AR content by experienced production workers and (2) the visualisation and processing of such content by novice workers. We, therefore, contribute a user study to the CSCW community that sheds light on the use of a particular type of AR-based CPPS for KES in industrial contexts.?

Negotiating Priorities on the Shopfloor: A Design Case Study of Maintainers’ Practices
In: Computer Supported Cooperative Work (CSCW), DOI: 10.1007/s10606-022-09444-5
Schlagwörter: CSCW; Design case study; Maintenance; Manufacturing; Qualitative research; Repair
Abstract Links

The coordination of maintenance work in manufacturing poses a crucial productivity factor in small and medium-sized companies (SMEs) but often seems to be rather neglected in practice as well as in much of the literature on maintenance. We shed light upon maintenance coordination work by presenting a design case study conducted in an SME over approximately two years. We took a participatory design-oriented approach, involving all roles on the shopfloor affected by maintenance work. In three major iterations during the pre-study, a release-ready prototype was developed and implemented by the users over the course of one year. The evaluation of the tool showed how a new and mostly unintended practice of information flow, error reporting, and prioritization emerged such that, for instance, foremen becoming a central node of communication, formal prioritization shifting away from higher management, and actual prioritization being done by maintainers. This paper contributes to the body of CSCW work on maintenance practice in SMEs by presenting detailed empirical findings on the coordination work of maintainers, as well as the evaluation of socio-technical interventions into maintenance practices.

Abstract Links

This article and the design fictions it presents are bound up with an ongoing qualitative-ethnographic study with Imazighen, the native people in remote Morocco. This group of people is marked by textual and digital illiteracy. We are in the process of developing multi-modal design fictions that can be used in workshops as a starting point for the co-development of further design fictions that envision the local population's desired digital futures. The design fictions take the form of storyboards, allowing for a non-textual engagement. The current content seeks to explore challenges, potentials, margins, and limitations for the future design of haptic and touch-sensitive technology as a means for interpersonal communication and information procurement. Design fictions provide a way of exposing the locals to possible digital futures so that they can actively engage with them and explore the bounds and confines of their literacy and the extent to which it matters.

Ethical Future Environments: Engaging refugees in Smart City participation
S. 1–5, DOI: 10.1145/3547522.3547704
Schlagwörter: italg; HCI; Participatory design; Smart Cities; marginalized people; refugees
Abstract Links

Aiming to improve quality of life for their citizens, cities and environments regions are becoming increasingly smarter. Smart City research and practice has put emphasis on the importance of citizen-centric processes, collaborating with citizens and other stakeholders, as well as public values in Smart City projects. Nevertheless, cities and governmental organizations continue to adopt technology-push approaches, marginalized citizens such as refugees are often excluded in (urban) digitalization and decision-making processes. Despite their different and valuable perspectives, collaborating with marginalized citizens is not common practice, as it often requires a different approach than traditional citizen participation techniques. During this workshop, we will discuss with Smart City practitioners and refugees how we could broaden participation to include citizens who are still excluded, using a visual card-based game to discuss topics in the Smart City context that are relevant to participants. The expected outcomes of this workshop are an understanding of opportunities for involving marginalized citizens (in this workshop: refugees) in Smart City projects, different perspectives of stakeholders involved, and the setting up of a learning and caring community in which different stakeholders can share their insights and practices.

Schlagwörter: a-paper; Care work; Communication technology; Configuration work; COVID-19 pandemic; Diary study; Digital literacy; Robots; Values; Work roles
Abstract Links

Technology use is a socially embedded process, especially when it comes to older adults and care. However, the restrictions associated with the COVID-19 pandemic have limited social contact to protect vulnerable groups in care homes, and even if technology use has increased in other areas, there is little known about the potential uptake of communication technology and changes in social interaction in the care context during a lasting crisis. This paper explores changes in communication technology use triggered by the pandemic at two care homes, using a qualitative diary study, online interviews and observations, and in-situ interviews within the care home with residents and workers. Our findings point to increasing use of tablets and video conference software triggered by COVID-related experiences, with implications for living and working in care homes. We also characterise the isolation experience of the residents, the workers’ concerns about the residents and changes in social interaction. We observed new areas of technology usage, associated changing work practices, technical affinity issues and context-specific attitudes towards future technologies. While the pandemic has triggered the use of communication technology in care homes on a small scale, this has also caused increasing workload and in particular articulation work, which requires support structures and the re-definition of work roles.

Design Evolution of a Tool for Privacy and Security Protection for Activists Online: Cyberactivist
In: International Journal of Human–Computer Interaction, S. 1-23, DOI: 10.1080/10447318.2022.2041894
Abstract Links

This work forms a part of a series of “on the ground” studies dealing with (post-)conflict situations, focusing on the iterative, participatory design of a tool, Cyberactivist, for protection for activists and the empirical research that led to it. Work on the development of privacy and security tools has not always recognized the fragile nature of the political processes in emerging democracies, frequent naivety about threat, nor the “occasioned” responses of activists because activism can be a “one time” endeavor, prompted by specific events. Researching political activism in Republika Srpska, we identified issues relating to the use of ICT and social media, leading to the redesign of our prototype which now raises awareness of privacy and security and supports activists by challenging ignorance, lowering exposure, and enabling remediation. We addressed “usable security” challenges to ensure simplicity of the tool and engaged with HCI researchers focused on international activism to assess the global applicability of the technical design.

Designing Multimodal Augmented- Reality Approaches in Sports: Collaborative and Competitive Scenarios for Individual and Group-based Outdoor Interaction
DOI: 10.48340/ecscw2022_p06
Abstract Links

This work presents a prototype for a multimodal and augmented (AR) based System designed for individual and joint activities in outdoor sports. Based on the need for social interaction and computer-supported collaborative sports and the decreasing physical activity across all ages, game scenarios for the context of outdoor sports were formulated and implemented with a head-worn multimodal AR interface. The System's innovation, flexibility, and multimodality found the basis for multiple use cases, such as professional and leisure, individual and group contexts. The technical infrastructure allows multimodal experiences while tracking and monitoring data such as movement speed, location, and heart rate. Within several game scenarios, players can cooperatively and competitively challenge themselves and other players to improve their physical activity playfully. This work is an inspiration and orientation for future research, development, and design of gamified AR exercising technologies.

This work presents a practice-based design and research approach that was used to explore individual, contextual, and institutional requirements, conceptualize and design AR-based Outdoor-scenarios for individual and joint activities in outdoor sports. Based on the need for social interaction and computer-supported collaborative sports and the decreasing physical activity across all ages, game scenarios for the context of outdoor sports were formulated and implemented with a head-worn multimodal AR interface. Members from seven different sports associations were interviewed and design workshops conducted to understand how to design AR-applications to promote an active lifestyle. The prototype and approach presented here will serve to discuss and reflect our future research activities, methodological concepts, and experiences in the field of HCI, CSCS, CSCW, and Design Communities.

Understanding Nomadic Practices of Social Activist Networks Through the Lens of Infrastructuring: the Case of the European Social Forum

Abstract Links

Within CSCW and HCI, an increasing body of literature has been demonstrating the essential relevance of infrastructures and infrastructuring to the work of people engaging in technologically mediated nomadicity. Tech Nomads – or T-Nomads, as they are sometimes called – not only rely on technological, human, and environmental infrastructural components – such as Wi-Fi, technical support, space, and basic resources such as light and power outlets – but they also have to engage in infrastructuring to mobilise their workplaces and effectively accomplish work in and across different locations. In this article, we bring an infrastructuring perspective to understanding nomadic practices concerning the organisation of complex collaborative events. We introduce findings from a long-term investigation focusing on how infrastructures are re-instantiated with the help of digital technologies, according to emerging demands from T-Nomads. Our findings demonstrate the need for a ‘non-essentialist’ approach to nomadicity, one which recognises the character of nomadic work and its varied aspects in different contexts. We extend the infrastructuring literature by demonstrating how infrastructuring work is done in a complex collaborative initiative, as the organisation of the annual European Social Forum.

Schlagwörter: italg; Animal-Computer Interaction; Caring Community; Citizen Science; Marginalization; Smart Cities; Urban Informatics; Vulnerability
Abstract Links

Over the past several decades the concept of smart cities has gained a lot of attention amongst researchers, the media, governments, civic groups and citizens. The literature shows that innovations have a more positive impact when they stimulate the development of cities and shape their space for a variety of participants, or when design is participatory. This ensures a non-technocratic approach, i.e., one that builds on the complexity of today's socio-technical systems and the consideration of their individual actors. Citizen-based approaches or one of the so-called Caring Community are possible answers to this. In this Design Fiction workshop, we take a critical view on the idea of smart cities by broadening participation to stakeholders who are still excluded from its concept and can be described as vulnerable and often marginalized, such as people who are (culturally) diverse (e.g. migrants, refugees, older adults, children, currently and formerly incarcerated people, homeless people and those with low income) or neurodiverse (e.g. people living with mental health challenges as autism or dementia or who suffer from functional impairments), and also animals and nature who are left behind in the whole digitization process. In this regard we will also address topics like sustainability and well-being. One of the expected outcomes of this workshop is the development of a holistic and sustainable smart city concept involving currently excluded stakeholders.

Abstract

Cyber-Physical Production Systems (CPPS) are receiving a lot of attention in the context of the fourth industrial revolution, especially in terms of complex architectures for data exchange among intelligent machines. However, the present elaboration is rather based on the question of what support such systems can provide for the exchange and appropriation of knowledge-intensive human practices in industrial surroundings. This paper presents the method and conceptual foundations of an Augmented Reality (AR) and sensor technology based CPPS for manual set-up processes on modern production machines. In the present context, both the recording of physical movements and the representation of local knowledge are potentially relevant. The basis is formed by design implications identified in the course of an extensive ethnographic study through the implementation of which a new methodological approach to the capture and transfer of (technical) knowledge embedded in embodied actions could be realized.

Treating Root Causes, not Symptoms: Regulating Problems of Surveillance and Personal Targeting in the Information Technology Industries
Abstract Links

As part of the Digital Markets Act, the EU Commission has proposed a new competition tool to address market power in the digital economy that is dominated by large online platforms. While limiting the power of US-based tech companies, such as Google or Facebook, can be helpful, we argue that limiting competition is not enough. Business models based on invasion of privacy and behavior modification are at the root of the associated problems stemming from their use are at the root of challenges to democracy and sustainability — in order to protect democracy and support sustainable development, Europe needs to develop alternatives to the current behaviorally targeted advertising business model. This policy brief discusses current alternatives to business models based on invasion of privacy and behavior modification, arguing that current alternatives need further development before implementation. To further support the development of new business models we argue in favor of regulatory sandboxes, digital ad revenue tax, reducing accumulation of data to technical necessity only, and adapting procedures and ethics from human subjects research.

Planning for Inclusive Design Workshops: Fostering Collaboration between People with and without Visual Impairment
In: 19th European Conference on Computer-Supported Cooperative Work, DOI: 10.18420/ecscw2021_ep27
Schlagwörter: italg
Abstract Links

Carrying out successful design workshops can be a challenging task. This can turn even more difficult, if one attempts to engage in more inclusive design workshops, where a broad range of user profiles are covered. If some of these profiles refer to people with impairments, things can get even more complicated. Furthermore, there are also associated challenges when trying to carry out something that is usually implemented as a face-to-face activity in an online format. This exploratory paper introduces a discussion on a few lessons learned from organising design workshops including both people with and without visual impairments. It also outlines our response to the situation created by the COVID-19 pandemic, which prevented us to engage in face-to-face design workshops. Based on feedback received from participants of a first in-person design workshop organised within one of our projects and on informal interviews carried out mainly over the phone to discuss ways to enhance the collaboration between people with and without visual impairments during such activities, we go on to introduce some relevant aspects that should be taken into consideration when planning inclusive design workshops. This is a preliminary contribution, meant to raise discussions on technology-mediated inclusive participatory design initiatives to further inform the development of a solid methodological contribution to CSCW.

Transitions by Methodology in Human-Wildlife Conflict - Reflections on Tech-based Reorganization of Social Practices
In: LIMITS ’21, S. 13
Abstract

Can cattle farmers live peacefully alongside lions, and what role can technology play in this sensitive setting? Since 2017, we have been investigating this question in the Okavango Delta, Botswana, using a Grounded Design (GD) approach. Based on community involvement we have been building and evaluating a system together with local and foreign experts which warns the locals when a lion comes near their village or their cattle and which has significantly reduced livestock predation by giving time for action. However, as our research shows, technology alone is not the solution for locals’ problems: education, knowledge transfer, economic self-determination, as well as the revival of herding traditions and lost connection to nature need to evolve further to foster a true coexistence between humans and predators in Botswana - and perhaps all over the world. To address these problems and solutions by design and ensure sustainability of its outcome, it is important to take into account the oral culture and collective history of the inhabitants with predators, especially lions. Consideration must also be given to their social environment and individual experiences and goals, as well as their digital infrastructure, accessibility, and digital ecologies. We therefore argue that the successful development of a design solution requires a holistic understanding of design that is built on inclusion, participation, collaboration, understanding, respect, sacredness and the always-recurrent cyclic renovation of life.

"What is the topic of the group, please?" On Migration, Care and the Challenges of Participation in Design
DOI: https://doi.org/10.1145/3476050
Abstract

An increasing number of people around the world are forced to leave their homes due to the climate catastrophe, regional conflict or poverty. In their new host countries however, refugees and migrants are frequently met by a wide range of challenges, including wider societal participation. The difficulties migrants and refugees face have also increasingly become the topic of HCI and CSCW work. In this paper we report on a three year-long project, involving refugees, migrants and activist supporters in a co-design project to develop tools that aid the process of resettling. Several aspects have challenged equal participation in the project, including divergent motives, unequal power distribution and cultural heterogeneity. Despite these challenges the project outcomes are in use and maintained beyond the project runtime through voluntary actors. We reflect on this discrepancy between process and outcome drawing on the concept of care.

Abstract Links

Within Participatory- and Co-Design projects, the issue of sustainability and maintenance of the co-designed artefacts is a crucial yet largely unresolved issue. In this paper, we look back on four years of work on co-designing tools that assist refugees and migrants in their efforts to settle in Germany, the last of which the project has been independently maintained by our community collaborators. We reflect on the role of pre-existing care practices amongst our community collaborators, and a continued openness throughout the project, that allowed a complex constellation of actors to be involved in its ongoing maintenance and our own, often mundane activities which have contributed to the sustainability of the results. Situating our account within an HCI for Social Justice agenda, we thereby contribute to an ongoing discussion about the sustainability of such activities.

Problems with surveillance capitalism and possible alternatives for IT infrastructure
In: Information, Communication & Society, S. 1-16, DOI: 10.1080/1369118X.2021.2014548
Schlagwörter: digital infrastructure; economics; IT business models; political manipulation; Surveillance capitalism
Abstract Links

Over the past two decades, the business model of surveillance capitalism has emerged in the IT industry. This model has turned out to be highly profitable, but, if left unchecked, will very likely undermine the foundations of liberal democracies and quality of life on this planet. It involves customized advertising and behavior manipulation, powered by intensive gathering and cross-correlation of personal information. There are significant indirect costs of this model, including loss of privacy, supporting surveillance by both the state and corporations, undermining the democratic process, other kinds of automated attempts of behavior manipulation, and excessive consumerism with its attendant environmental costs. Turning to what could be done, we propose a co-development of regulation and technology, as well as the key roles that can be played by citizens and civil society organizations. The regulatory measures are intended to safeguard privacy, require true informed consent, and to foster interoperability (even among rival firms, nonprofit organizations, and others). We also identify key enabling technologies, including open source, APIs to support interoperability and portability, encryption, and peer-to-peer systems. Finally, we discuss the crucial role of ownership structures for these IT services and argue for an ecosystem approach as a counter narrative to surveillance capitalism.

Abstract Links

There is a developing recognition of the social and economic costs entailed in global supply chains. In this paper, we report on efforts to provide alternative, more sustainable and resilient models of production. Community Supported Agricultures (CSAs) address this problem but require new means of exchange which, we suggest, offer a design opportunity for sustainable HCI research. This paper presents a two months participatory observation in a food movement, a German CSA which developed a distribution system involving their own currency. Based on our ethnographic observations, we focus our discussion on (1) the solidaristic principles upon which the movement is based and (2) techniques of mediating between consumers’ wishes and the constraints of local agricultural production. By relating to the continued development of CSAs, we identify three interrelated innovation gaps and discuss new software architectures aimed at resolving the problems which arise as the movement grows.

HCI’s Role in the Capitalocene: Lessons Learned from an HCI Master Course Across the Globe
In: LIMITS Workshop on Computing within Limits, DOI: 10.21428/bf6fb269.67a8d057
Abstract

Various concepts have attempted to capture the nature of the contemporary political-economic system of globalised capitalism and its disastrous consequences for the planet, including World System Analysis or the Capitalocene. Especially Decolonial thinkers see its roots in colonialism. The resulting modernity/coloniality structures many aspects of human life everywhere, including gender identities, relationships amongst humans and with nature. Technology plays a vital part, requiring reflections on how HCI researchers can react to these challenges. In a class of an HCI master program, we have attempted to jointly begin to understand HCI’s role in the capitalocene by studying relevant concepts and empirically investigating specific local yet connected phenomena. With participants being distributed across the globe, we were able to study different shared yet locally specific phenomena inspired by multisited ethnography.

Growing Together, Remaining Apart: The Role of Digital Technology in Former Guerrilla Fighters' Social Capital
In: ACM on Human-Computer Interaction, S. 331:1–331:24, DOI: 10.1145/3476072
Schlagwörter: FARC; reincorporation; social capital; technological use; transition
Abstract Links

In this paper, we present an account of how FARC-EP ex-combatants are using digital technology in the process of reincorporating into Colombian society. We report findings showing how this technology mediates the difficult task of transitioning from a culture of opposition to civilian members and active political actors. Using the concept of social capital as a framework, we investigate the intersection between the use of digital tools and developing cultural and economic practices among these groups during this transitional period. Reflecting on the bonding and bridging aspects of social capital, we describe how ex-combatants draw on substantial social capital from their former lives as a guerrilla army in order to strengthen their position in these new circumstances, and their cautious and difficult creation of new social ties with wider Colombian society. We contribute to the CSCW discourse by discussing the crucial role digital tools, previously not available to these groups, play in sustaining, re-growing and building social capital of communities in post-conflict periods.

Abstract Links

It is sometimes argued that there is hardly a place in the world in the 21st century left untouched by global capitalism [111, 112]. Even so, some places remain at the periphery, participating in this system without being fully absorbed by it. In this article, we take a detailed look at the economic life of such a “pericapitalist” [161] community in the Brazilian Amazon region. We detail how the community increasingly participates in global systems and supply chains, yet also organizes economic life around local and traditional values. We pay special attention to the role of digital technologies in the community, including mobile phones and internet. The contribution of the article is as follows: firstly, it provides a detailed analysis of the material practices of a community at the edge. Secondly, it draws attention to the heterogeneous nature of responses to global capitalism, formed from the relationship between specific material practices, new technology, and elements of cultural identity. Thirdly, it argues for an increased sensibility towards these different relations to capitalism when considering design implications. We argue that close attention to material practice goes some way towards resolving those tensions and, further, provides for an appeal to a more pluralistic views of culture and development [61].

Abstract

Scrum, the most popular form of agile, is often cited for creating a positive working environment for women. Its values, principles, roles, and practices are said to hold great potential to promote fairness and gender equality. But does it? Social scientific literature has identified two key dimensions to analyze processes. The first dimension examines whether practices, behaviors, values, and attitudes are explicit or implicit. The second dimension separates the team experience from the individual experience. Using these dimensions to inform thinking about gender issues in processes and our data from women working on Scrum teams, we developed an analysis framework to surface gender issues in Scrum. We share what works and doesn’t work for women in Scrum and where improvements can be made.

Coping with Messiness in Ethnography: Authority, Bias and Immersion in ethnographic Fieldwork in the non-Western World
S. 1–5, DOI: 10.1145/3411763.3441328
Abstract Links

Ethnography has firmly established its position in the Human-Computer Interaction (HCI) community. Many studies have benefited from following ethnographic approaches to arrive at a grounded and comprehensive understanding of the respective research context. Applying that to the non-Western world, however, comes with challenges for researchers. Aside from ethical concerns which have been addressed in the past, we want to use this workshop to foster conversations and discussions on authority, bias and immersion when conducting ethnographic field work in the non-Western world – especially as a Western researcher. The main objective of this workshop is to exchange experiences and to identify common aspects and ways of overcoming, coping with or even embracing the messiness in ethnographic work and derive guidelines based on these discussions.

Alexa, We Need to Talk: A Data Literacy Approach on Voice Assistants
S. 495–507, DOI: 10.1145/3461778.3462001
Abstract Links

Voice assistants (VA) collect data about users’ daily life including interactions with other connected devices, musical preferences, and unintended interactions. While users appreciate the convenience of VAs, their understanding and expectations of data collection by vendors are often vague and incomplete. By making the collected data explorable for consumers, our research-through-design approach seeks to unveil design resources for fostering data literacy and help users in making better informed decisions regarding their use of VAs. In this paper, we present the design of an interactive prototype that visualizes the conversations with VAs on a timeline and provides end users with basic means to engage with data, for instance allowing for filtering and categorization. Based on an evaluation with eleven households, our paper provides insights on how users reflect upon their data trails and presents design guidelines for supporting data literacy of consumers in the context of VAs.

‘Technology is Everywhere, we have the Opportunity to Learn it in the Valley’: The Appropriation of a Socio-Technical Enabling Infrastructure in the Moroccan High Atlas
In: Computer Supported Cooperative Work (CSCW), DOI: 10.1007/s10606-021-09401-8
Abstract Links

This paper describes the appropriation processes involved in establishing a socio-technical enabling infrastructure in a valley in the High Atlas of Morocco. We focus on the challenges of co-establishing such an intervention in a rural/mountainous region that is already undergoing a process of continuous development and profound transformation. We reflect upon the changes and unforeseen appropriation by our local partners and inhabitants in the valley of a computer club primarily used as an informal learning centre for school children. We followed an ethnographic approach and combined research perspectives from both socio-informatics and anthropology. This paper sheds light on what a successful cooperation and intervention in this kind of challenging environment can look like. It does this by taking seriously competing expectations, fragile infrastructural foundations and the socio-cultural context. Despite the challenges, the intervention managed to lead to the establishment of a socio-technical enabling infrastructure that plays a particularly valuable role in local educational endeavours and that is now moving towards supporting other members of the community. The paper thus provides insights regarding what has to be considered to create a mutually beneficial cooperation with all relevant stakeholders as well as a sustainable intervention.

Schlagwörter: AI; Data; Ethics; Global South; HCI4D; ICT4D; Marginalized people; ML; Privacy; Security
Abstract Links

There has been increasing interest in socially just use of Artificial Intelligence (AI) and Machine Learning (ML) in the development of technology that may be extended to marginalized people. However, the exploration of such technologies entails the development of an understanding of how they may increase and/or counter marginalization. The use of AI/ML algorithms can lead to several challenges, such as privacy and security concerns, biases, unfairness, and lack of cultural awareness, which especially affect marginalized people. This workshop will provide a forum to share experiences and challenges of developing AI/ML health and social wellbeing technologies with/for marginalized people and will work towards developing design methods to engage in the re-envisioning of AI/ML technologies for and with marginalized people. In doing so we will create cross-research area dialogues and collaborations. These discussions build a basis to (1) explore potential tools to support designing AI/ML systems with marginalized people, and (2) develop a design agenda for future research and AI/ML technology for and with marginalized people.

CareFox: An Interactive Learning Application for Care-Students
DOI: 10.18420/IHC2021_003
Abstract Links

Demographic transformation and medical-technical progress are generating new demands for standards and quality in professional caregiving. The job profile and especially the nature of care apprenticeships is changing significantly and use of digital media is becoming an increasingly ubiquitous and important aspect of the work. In this paper, we present a design case study that focuses on the development and evaluation of a multimedia learning application for and with care students. Adopting a user-centered design approach, we collected design requirements for the application in workshops and interviews with 23 care-students. The results show that it is important to create a structured approach to providing information and that social aspects such as chat allow for higher motivation and collaboration in learning. The findings also suggest that, by using game mechanisms such as a quizzes and difficulty levels, care-students can be further motivated to become more engaged with learning content.

The Role of Digitalization in Improving the Quality of Live in Rural (Industrialized) Regions
S. 1–2, DOI: 10.1145/3464385.3467686
Schlagwörter: digitalization; industrial transition; rural regions
Abstract Links

Rural regions in the EU and all over the world are often characterized by divers’ conditions and aspects, such as - geographical, landscape, digital infrastructures, socio-economic, demographic, cultural and environmental as well as hierarchically grown decision structures and dense social networks among their inhabitants. Digitalization and improving quality of live in rural and industrialized regions is a transformative, yet complex process, that depends inherently on the ability of regions to face challenges in modernizing their industrial base, upgrading the skills of the workforce, compensating for job losses in key sectors, enhance well-being and living standards and improve their contribution to national performance and more inclusive and resilient societies. With this workshop, we aim at contributing to this growing field by sharing experiences, identifying interdisciplinary perspectives about regions in industrial and digital transition to become more resilient in the context of major shifts brought about by globalization, decarbonization and ongoing technological change.

Abstract Links

This paper introduces the praxeologically grounded research programme on socio-informatics developed at the University of Siegen and the International Institute for Socio-Informatics in Germany. We outline our methodological framework of grounded design, guiding and binding together a variety of different engagements in practice which we call design case studies (DCS). While grounded design is applied to a broad variety of different areas, in this paper we deal specifically with our engagements in support of communities and political activists. To exemplify our approach, we present one DCS: It focuses on the participatory development of a computer club in the High Atlas as a facilitation infrastructure to support public community participation in the process of modernization and social transformation in the Maghreb. Insights into the project context, the objectives and methodology and the depiction of some of its first findings lays the ground for the discussion of socio-informatics research principles.

Schlagwörter: Augmented-reality; Cyber-physical systems; Design case studies; Design implications; Industrial contexts; Practice-centred design; Sensors
Abstract

Industrial set-up has long been a focus of scientific research, largely because it entails substantial cost overhead for manufacturing companies. Whilst various efforts have been made to optimise this process, mainly in terms of time and other resources needed to accomplish it, to date little can be found in the HCI literature about how digital technologies can support workers who engage in it. This article sets out to addresses this gap in the literature by introducing a design case study carried out for the conception of a CPPS (Cyber-physical Production System) to support machine operators with industrial set-up. Our contribution is therefore threefold: first, we describe and discuss the results of an in-depth ethnographic study, carried out under the premises of the grounded design research paradigm, to uncover practices of machine operators to inform design. Second, we introduce a series of design implications drawn from those results. Finally, we demonstrate how those design implications have informed the participatory design activities pursued for the conception of the CPPS in question. In so doing, we advance the state of the art on the design of digital technologies to support people working with industrial set-up and open new research directions on the subject.

Psychosocial ICT: The Potential, Challenges and Benefits of Self-help Tools for Refugees with Negative Mental Stress
DOI: 10.18420/ecscw2020_ep11
Schlagwörter: italg
Abstract Links

Information and Communication Technology (ICT) has penetrated almost all areas of life today and has the potential to create positive change. This paper addresses the opportunities offered by ICT for improving the resilience and psychosocial well-being of refugees who have experienced mentally stressful events when forced to leave their home country and seek shelter in a different host country. We want to distinguish between perceived stress and clinically-defined trauma, for which therapeutic interventions require direct personal contact with psychological experts. However, we also want to focus on the digital possibilities that currently exist to support establishing this kind of personal connection. Many refugees need to seek psychological help, but social, economic and cultural barriers hold them back. Our qualitative study with refugees, psychologists and volunteers provides insights into how refugees deal with their mental issues and the challenges they face in everyday life. We aim to show that ICT can play a major role in terms of addressing awareness and self-empowerment as an entry point for this vulnerable group. We also discuss the potential challenges and benefits of ICT for refugees seeking to recover their mental stability.

Abstract Links

The number of women in IT is still low and companies struggle to integrate female professionals. The aim of our research is to provide methodological support for understanding and sharing experiences of gendered practices in the IT industry and encouraging sustained reflection about these matters over time. We established a Living Lab with that end in view, aiming to enhance female participation in the IT workforce and committing ourselves to a participatory approach to the sharing of women's experiences. Here, using the case of a German video game company which participated in our Lab, we detail our lessons learned. We show that this kind of long-term participation involves challenges over the lifetime of the project but can lead to substantial benefits for organizations. Our findings demonstrate that Living Labs are suitable for giving voice to marginalized groups, addressing their concerns and evoking change possibilities. Nevertheless, uncertainties about long-term sustainability remain.

Schlagwörter: employer branding; external communication; gender, video game industry; living lab; qualitative research; talent acquisition
Abstract Links

Participation of women in IT is still low and companies wonder which external communication measures are necessary to attract more female personnel. To gain a richer understanding of adequate gender sensitive ways of communicating towards girls and women, one needs to take into account contextual challenges. Following a Participatory Action Research approach, we conducted a qualitative field study in a video game company in a large city in Germany, identified areas of concern, and sketched out implications for gender-sensitive communication measures together with our participants. Findings show that addressing gender stereotypes, making role models visible, and using adequate channels is relevant. Some problems might be solved via short-term solutions, but the majority require a long-term perspective. Our lessons learned leave implications for companies in the IT sector who want to foster gender sensitive external communication measures and can contribute to the realization of more gender balanced working environments.

Abstract Links

A large portion of the software side of the global information technology infrastructure, including web search, email, social media, and much more, is in many cases provided free to the end users. At the same time, the corporations that provide these services are often enormously profitable. The business model that enables this involves customized advertising and sometimes behavior manipulation, powered by intensive gathering and cross-correlation of detailed personal information. These companies provide some great products and services at no upfront cost to the end users. But the model has a dark side as well, with negative impacts for privacy, autonomy, human dignity, and democracy. The purpose of this panel is to provide a civil forum for the CHI community as a whole to discuss this business model, including its advantages and disadvantages, and its impacts on CHI and HCI and society more generally, with an eye toward responsible innovation.

Schlagwörter: a-paper; elderly care; ethics; social robots; user studies
Abstract Links

Ageing societies and the associated pressure on the care systems are major drivers for new developments in socially assistive robotics. To understand better the real-world potential of robot-based assistance, we undertook a 10-week case study in a care home involving groups of residents, caregivers and managers as stakeholders. We identified both, enablers and barriers to the potential implementation of robot systems. The study employed the robot platform Pepper, which was deployed with a view to understanding better multi-domain interventions with a robot supporting physical activation, cognitive training and social facilitation. We employed the robot in a group setting in a care facility over the course of 10 weeks and 20 sessions, observing how stakeholders, including residents and caregivers, appropriated, adapted to, and perceived the robot. We also conducted interviews with 11 residents and caregivers. Our results indicate that the residents were positively engaged in the training sessions that were moderated by the robot. The study revealed that such humanoid robots can work in a care home but that there is a moderating person needed, that is in control of the robot.

Abstract Links

Currently, there is a broad range of studies dealing with the design and visualization of energy consumption data for the domestic and increasingly for the office context. However, studies addressing the industrial context are quite rare, and due to the diversity of machines, processes, tasks, personal motivations, teams and the specific organizational culture of companies, it is not sufficient to provide only consumption data. For an adequate consideration of these factors, detailed design guidelines and system concepts are currently missing. However, this study shows the potential that a common understanding of consumption data can emerge through suitable visualization to support everyday work and possibilities of data sharing. Therefore, we show exemplarily how a design can be derived from empirically collected requirements and how a system concept can look like that enrich current eco-feedback design research for the industrial context.

Investigating the use of digital artifacts in a community project of sustainable food practices: 'My chili blossoms'
S. 1–4, DOI: 10.1145/3419249.3420089
Schlagwörter: italg; Grassroots; HFI; Sustainability; Sustainable HCI; Learning; Community; Food
Abstract Links

Research on food practices has become more common among scholars of HCI in recent years. Human-Food-Interaction (HFI) looks into the interplay of humans, food and technology. HFI, even so, has paid relatively little attention to the more collective elements of food practice, including social bonding [1]. The modest project we describe below aimed to say something about the use of digital artifacts to support community engagement for sustainable food practices. We participated, as action researchers (see [2]) in a grassroots movement that instigated a project around learning about food growing, using digital means to bring interested people together during times of physical distancing: In the project Vegetables seek a home, people from various backgrounds ‘adopted’ a chili-plant, they are invited to share what they like in a Telegram-Group, and to get learning-modules via a mailing-list. Through an analysis of the communal effort to actualize the project (video-calls, Telegram, wechange.de) and the content of the Telegram-Group for the chili-plant adopting parents and experts, we suggest some design implications for grassroots communities and sustainable food practice. In future research we intend an iterative design to support the community and its project, utilizing Holmgren's 12 principles of permaculture design.

Schlagwörter: cryptocurrencies; economics; Facebook; Libra; monetary diversity
Abstract Links

Money underpins everyone's daily life. Possible solutions for the global problems fail if there is not enough money. Yet changes to our monetary system are rarely included in the discussion. Against this backdrop, cryptocurrencies create important new precedents regarding how money can be created. Libra is a recent cryptocurrency project launched by one of the dominant social media companies, which has been the subject of intense international discussion. Because the details of Libra are not yet fully specified, we present different scenarios of how a successful Libra currency might play out and some of the problems that might follow. These scenarios include the monetization of the payment infrastructure, (ab)use of sanctioning power, a reduction of the reserve ratio, and an abandonment of reconvertability. These problems suggest a number regulatory strategies in response. Finally, we describe values and design requirements that might help guide future cryptocurrency innovation and provide ways of evaluating their success or failure.

Schlagwörter: passengers; robo-taxi; service design; shared autonomous vehicles; wizard of oz
Abstract Links

Autonomous driving enables new mobility concepts such as shared-autonomous services. Although significant re-search has been done on passenger-car interaction, work on passenger interaction with robo-taxis is still rare. In this paper, we tackle the question of how passengers experience robo-taxis as a service in real-life settings to inform the interaction design. We conducted a Wizard of Oz study with an electric vehicle where the driver was hidden from the passenger to simulate the service experience of a robo-taxi. 10 participants had the opportunity to use the simulated shared-autonomous service in real-life situations for one week. By the week's end, 33 rides were completed and recorded on video. Also, we flanked the study conducting interviews before and after with all participants. The findings provided insights into four design themes that could inform the service design of robo-taxis along the different stages including hailing, pick-up, travel, and drop-off.

Fostering Accessibility at the Workplace through Community-based Participatory Research
In: European Society for Socially Embedded Technologies (EUSSET), S. 13, DOI: 10.18420/ecscw2020_ws07
Schlagwörter: italg
Abstract Links

This workshop sets out to provide a forum for discussing the potential of community-based participatory research (CBPR) to foster accessibility at the workplace. It aims at opening a space to engage people with and without disability in a discussion about how this approach can contribute to bring employees, employers, developers and researchers together for the elaboration of a sensitisation concept to make people aware of the relevance of developing and adopting highly accessible digital solutions for the workplace. In particular, it focuses on the potential of the approach to engage people with disability in research, development and, most importantly, in the job market. Ultimately, the workshop seeks to advance the discussion of how this type of research can contribute towards the inclusion of people with disability in society and to highlight the benefits of that. The workshop is based on the European CSCW tradition of using in-depth qualitative methodologies for workplace studies and practice-based computing. It addresses issues of cooperation and collaboration between research actors, in the pursuit of a deep understanding of work contexts and the design of socio-technical systems that respond to their emerging needs.

In: CHI Conference on Human Factors in Computing Systems, S. 1-5, DOI: 10.1145/3411763.3441328
Abstract Links

There are several frameworks and approaches, addressing how to conduct ethnographic and qualitative field work in various settings. However, going by the book might not be an option when conducting research in politically charged, unstable or simply non-western regions. Politics, social pressure and even someone’s personal safety might be necessary to consider. Another important area to consider are research ethics. Privacy policies might do their work with regard to existing laws which differ from each country and should ensure no harm for all involved parties, but how can this be guaranteed and does it also cover all aspects of ethics? Including stakeholders as a basis for user-centered work and design is common. But what does participation mean in such contexts? The questions are: What is important to consider when conducting ethnographic field work in such settings? How can we foster different degrees of genuine participation? How can we ensure, that the work we do is ethically correct without endangering the research outcome? In this workshop, we invite researchers and practitioners to rethink existing methods and approaches and start working on guidelines, that better serves the needs of such specific and to some extent critical circumstances.

Messy Fieldwork: A Natural Necessity or a Result of Western Origins and Perspectives?
S. 185–190, DOI: 10.1145/3393914.3395864
Schlagwörter: ethics; ethnography; fieldwork; global south; methods; non-western; participation; western
Abstract Links

With this Provocation, we aim at starting a dialogue between researchers who struggle with applying qualitative and ethnographic methods and following approaches in non-Western settings. Going by the book might not be an option when conducting research in politically charged or un-stable regions. Local politics, social pressure and even people's personal safety are aspects that require consideration. Based on our experience from conducting fieldwork in Morocco, Palestine and Botswana, we reflect upon the difficulties we came across. We argue that, messiness, to some extent comes naturally with immersive fieldwork. On the other hand, in order to find 'clean' ways of conducting ethnographic fieldwork in non-Western contexts, novel forms of (applying) methods are needed. By providing questions regarding three different aspects (applying methods on the Ground, Ethics, and Participation) we encourage researchers to reflect upon their own experiences.

Social Technology Appropriation in Dementia: Investigating the Role of Caregivers in Engaging People with Dementia with a Videogame-based Training System
S. 1–15, DOI: 10.1145/3313831.3376648
Schlagwörter: a-paper; appropriation; care; caregiver; dementia; exergame; ICT
Abstract Links

There has been increasing interest in designing for dementia in recent years. Empirical investigation is now needed of the long-term role of caregivers in appropriating ICTs into the complex daily life of people with dementia (PwD). We present here the outcomes of a 4-month evaluation of the individual, social and institutional impact of a videogame-based training system. The everyday behavior and interactions of 52 PwD and 25 caregivers was studied qualitatively, focusing on the role played by caregivers in integrating the system into daily routines. Our results indicate that the successful appropriation of ICT for PwD depends partly on the physical, cognitive and social benefits for PwD, but especially on the added value perceived by their social care-network. We discuss the need for design in dementia to develop more socially embedded innovations that can address the social actors involved and thus contribute to practical solutions for professional and private care.

Insights from an Exergame-Based Training System for People with Dementia and Their Caregivers
In: HCI and Design in the Context of Dementia, S. 289-301, DOI: 10.1007/978-3-030-32835-1_18
Abstract Links

As a result of aging societies, the prevalence of dementia, and accordingly the need for care is increasing. The use of information and communication (ICT)-based technologies may facilitate and promote a self-sustaining lifestyle for people with dementia and their caregivers. In this article, the authors provide results from a design study of an ICT-based system to support activity and mobility for people with dementia and their care-network. The authors investigated practices, attitudes and the social contexts of 26 people with dementia and their caregivers and designed an ICT-based prototype system that was evaluated afterwards in a four-month evaluation study. Here, the goal was to assess usability, user experience and acceptance and to analyze the effects of system usage on physical, cognitive and socio-emotional conditions of people with dementia and their caregivers. Our results indicate that the system supports people with dementia and their related caregivers partly during their social and daily activities and improves their quality of life. Furthermore, results suggest that motivation, collaboration and cooperation among the parties involved were increased by using the system. Integration and social embeddedness of ICT-based systems into the daily lives of people is the key for long-term and sustainable use. However, the involvement of caregivers and stakeholders seems to be an additional facilitating factor for daily life integration and may promote long-term use.

Notes of memories: Fostering social interaction, activity and reminiscence through an interactive music exergame developed for people with dementia and their caregivers

Schlagwörter: a-paper; activity; care; Dementia; exergame; ICT; memories; music; participatory design; reminiscence; social interaction; videogame
Abstract Links

This paper presents the outcomes of an exploratory study focused on the evaluation of an interactive music exergame for People with Dementia (PwD) and their caregivers. PwD tend to isolate themselves from the outside world, therefore carers need to develop strategies to maintain communication with them. Studies indicate that music–based activities provide an effective way to achieve social interaction with PwD. At the same time, physical activity plays a major role in dementia-related interventions because it can slow down progression and provide meaningful stimulation. Our developed interactive music game bounds these two concerns together; we evaluated the system afterwards regarding its individual and social impact and its integration into the daily routines of both PwD and their caregivers, focusing on its capacity to provide both enjoyment and relief from some of the effects of dementia. Qualitative data collected over 4 months confirmed the valuable impact of music-based interventions of PwD. Of particular note was how PwD used the game to improve or maintain their physical condition while recovering past memories and an interest in social interaction.

Abstract Links

Social media as well as information and communication technology (ICT) play a major role in different conflicts all over the world. They have been crucial tools in the beginning of the so-called `Arab Spring' in Tunisia, the ongoing war in Syria, the struggle of Palestinian activists but also the Ukraine-Russia conflict. In this work, we provide the readers with an overview of current state of affairs regarding the use of ICTs in general and social media in particular in conflicts. Afterwards, we discuss how and what kind of tools and methods different actors use in their struggle. We especially focus on how actors appropriate the available tools to suit the specific conditions they find themselves in, such as risks of online surveillance, danger of prosecution of themselves or close others and varying levels of connectivity. We finally discuss the importance of an embedded perspective on the use of ICTs in conflict to understand these practices of appropriation.

The Social Mile - How (Psychosocial) ICT can Help to Promote Resocialization and to Overcome Prison

Abstract Links

There is currently uncertainty in the research community as to how ICT can and should be designed in such a way that it can be convincingly integrated into the everyday lives of prison inmates. In this paper, we discuss a design fiction that closes this research gap. The descriptions and results of the study are purely fictitious. Excluded is the State of the Art as well as the description of the legal situation of prisons in Germany. The analysis of the fictional study data designed here thus refers to the real world in order to derive ethical guidelines and draw practical conclusions. It is our intention to use these results as a possible basis for further research. The paper presents results of an explorative study dealing with the design, development and evaluation of an AI-based Smart Mirror System, Prison AI 2.0, in a German prison. Prison AI 2.0 was developed for daily use and voluntarily tested by eight prisoners over a period of 12 months to gain insight into their individual and social impact, with an emphasis on its ability to actively support rehabilitation. Based on qualitative data, our findings suggest that intelligent AI-based devices can actually help promote such an outcome. Our results also confirm the valuable impact of (Psychosocial) ICT on the psychological, social and individual aspects of prison life, and in particular how prisoners used the Smart Mirror system to improve and maintain their cognitive, mental and physical state and to restore social interactions with the outside world. With the presentation of these results we want to initiate discussions about the use of ICT by prisoners in closed prisons in order to identify opportunities and risks.

Schlagwörter: italg
Abstract Links

In this paper, we describe the feminist perspectives that have informed design in the HCI community, and develop an argument for an approach that translates these broad commitments into a pragmatic design space, drawing on emancipatory agendas such as participatory design. As designers of technologies, we regard creating research infrastructures that offer safe spaces for the development of user-centered artifacts based on diverse and critical perspectives as not only a utopian vision, but as a practical contribution to a more equal society. Shaowen Bardzell stresses this point when she states that in envisioning utopias, we are “seeking not so much to predict the future, but rather to imagine a radically better one”. Recognizing that technology shapes social life and amplifies social practices both good and bad, research in the field of Human-Computer Interaction (HCI) increasingly focuses on how technology has been developed in the past, and how constructive futures may be envisaged. More and more, academics are inviting multidisciplinarity and embracing ethnographic methods as part of the design of networks and technical artifacts, realizing that innovation cannot be user-centered if designers employ a bird’s-eye perspective. This leads to an approach that advocates designing socially embedded technologies in real world environments. Thus, for some time now, collaboration and participatory design approaches have provided a means for enacting positive social and technological change. If we agree that “those who design technologies are […] designing society”, new questions arise in terms of responsibility for the future shape of the world: How do we design technologies to design a better society for people of all genders?

LionAlert – Participatory Design and Evaluation of an Interactive Notification System to Reduce Human-Lion Conflicts in Rural Botswana
S. 147
Schlagwörter: thesis
Abstract Links

Das Okavango Delta in Botswana, einem Land im südlichen Afrika, ist berühmt für seine Artenvielfalt. Doch das beliebte Touristenziel wird auch von zahlreichen Menschen in direkter Nachbarschaft zu Nationalparks bewohnt. Wenn die Weideflächen ihrer Nutztiere mit dem Territorium von Raubtieren überlappen, sind fatale Konflikte die Konsequenz: etwa 250 Angriffe auf Rinder wurden im Jahr 2017 in vier untersuchten Dörfern gemeldet, von denen 87 % von Löwen stammen. Nicht nur die Existenz und Sicherheit der Farmer sind bedroht: unzureichende staatliche Entschädigung führt auch zu Frustration, einer negativen Wahrnehmung und sogar Verfolgung von Löwen. Um dieses Problem zu lösen und Konflikte auf ein Minimum zu reduzieren, hat die Non-Profit-Organisation CLAWS (Communities Living Among Wildlife Sustainably) ein GPS-Tracking von Löwen mittels Halsbändern und ein Warnsystem namens LionAlert etabliert, bei dem Forscher die Einheimischen per SMS warnen, wann immer ein Löwe einen kritischen Bereich betritt. Während das bereits geholfen hat, die Angriffe um 50 % zu reduzieren, bestehen weiterhin viele Probleme, darunter ein statischer Signal-Bereich und -Zeitraum, Netzwerk-Instabilität, die Ineffizienz manueller Warnungen sowie Faktoren, die Empfänger davon abhalten, angemessen zu reagieren. Diese Masterarbeit beschäftigt sich mit einer Lösung für diese Probleme, indem ein interaktives Interface für eine neue, automatisch betriebene Version von LionAlert designt und evaluiert wird. Dafür wurden die Methoden der Design Case Studies und des Participatory Design angewandt (Schuler & Namioka, 1993; Wulf et al., 2018). In einem Zeitraum von drei Wochen im August 2018 wurden in einem interdiszplinären Team zwei Runden von Workshops mit 35 Teilnehmern aus drei Dörfern im Okavango Delta durchgeführt. Diese dienten dazu, die aktuelle Situation der betroffenen Parteien, die Adoption und Nutzung des Systems sowie Verbesserungspotentiale herauszustellen, die die initialen Anfoderungen für das aktualisierte System identifizierten. Ein Prototyp des Interfaces mit den Aussagen und Vorschlägen der Teilnehmer wurde daraufhin im zweiten Workshop evaluiert und diskutiert. Basierend auf Feedback aus den Workshops sowie von lokalen Forschern und eigenen Beobachtungen wurde ein finaler Prototyp entwickelt, der schließlich in einer automatisierten Version implementiert wird, die eine Tablet-basierte Warn-Station sowie Apps für verschiedene Arten von mobilen Geräten impliziert. Weitere Implikationen und Limitationen für die weitergehende Linderung des Mensch-Tier-Konflikts mit Informations- und Kommunikationstechnologien (ICT) wird diskutiert.

Cyber-Physical Systems for Knowledge and Expertise Sharing in Manufacturing Contexts: Towards a Model Enabling Design
In: Computer Supported Cooperative Work (CSCW), Volume: 28 No.:3, S. 469-509, DOI: 10.1007/s10606-019-09355-y
Abstract Links

Cyber-physical systems (CPS) are currently attracting a great deal of attention as a part of the discourse surrounding the fourth industrial revolution. Thus far, the chief focus has been upon complex architectures for supply chain-wide data exchange between intelligent machines. Here, however, we take a very different tack by examining the support CPS may offer for the exchange and acquisition of knowledge-intensive human practices in the context of manual set-up processes on modern production machines. The paper offers contributions to both CSCW and the ongoing development of CPS in three ways. Firstly, it presents a detailed empirical study of knowledge and expertise sharing practices in a production environment. Secondly, the results of this study are used as the basis of an over-arching model that was developed with the express purpose of facilitating design. Finally, CPS-based technical possibilities are matched to the practice-relevant knowledge and expertise sharing requirements captured within the model.

Abstract Links

Digital participation has become an important issue in modern societies, typically focusing on groups prone to marginalization. From this perspective, less attention has yet been paid to imprisoned persons. Many penitentiary systems are formally characterized by the basic requirement of resocialization. Accordingly, life in prison should be largely adapted to conditions outside and to fundamental social changes, which must be considered in designing the framework for prison systems. Still, the digital opening of the prison is debated controversially, not least due to anticipated security issues. Hence, to raise awareness about challenges for digital participation of prisoners, we conducted a knowledge-sociological analysis (SKAD) of the public discourse on the use of ICT by prison inmates in Germany. We thereby seek to advance knowledge and insights from social and organizational practice arising from the use of ICT in context of total institutions and create the basis for action from a socio-informatics perspective.

Schlagwörter: language learning; migrants; participatory design; refugees
Abstract Links

For migrants and refugees, settling in a host country often proves hugely problematic. The ability to communicate marks a significant step in the process of resettlement. The current high number of migrants coming to Europe has therefore meant that the need to improve and increase the availability of language provision has become more pressing. Nevertheless, due to the complexity of financial and legal regulations and of policy restrictions, access to and information about available courses are in practice hard to find, and non-funded volunteer initiatives are scarcely visible at all. To address this problem, a newly developed language-course wizard provides orientation for refugees and migrants. Findings indicate that its visual representation is apt to span a broad range of cultural as well as educational backgrounds. Our work demonstrates the need for a detailed approach to understanding the challenges that refugees and other migrants face in practice. Failing this, services frequently do not reach those they are intended for.

Lions at the Gates: Trans-disciplinary Design of an Early Warning System to Improve Human-Lion Coexistence

Abstract Links

Across Africa, lions (Panthera leo) are heavily persecuted in anthropogenic landscapes. Trans-disciplinary research and virtual boundaries (geofences) programmed into GPS-tracking transmitters offer new opportunities to improve coexistence. During a 24-month pilot study (2016-2018), we alerted communities about approaching lions, issuing 1,017 alerts to four villages and 19 cattle posts. Alerts reflected geofence breaches of nine lions (2,941 monitoring days) moving between Botswana’s Okavango Delta and adjacent agro-pastoral communities. Daily alert system costs per lion were US$18.54, or $5,460.24 per GPS deployment (n = 13). Alert-responsive livestock owners mainly responded by night-kraaling of cattle (68.9%), significantly reducing their losses (by $124.61 annually), whereas losses of control group and non-responsive livestock owners remained high ($317.93 annually). Community satisfaction with alerts (91.8%) was higher than for compensation of losses (24.3%). Study lions spent 26.3% of time monitored in geofenced community areas, but accounted for 31.0% of conflict. Manual alert distribution proved challenging, static geofences did not appropriately reflect human safety or the environment’s strong seasonality that influenced cattle predation risk, and tracking units with on-board alert functions often failed or under-recorded geofence breaches by 27.9%. These insufficiencies prompted the design of a versatile and autonomous lion alert platform with automated, dynamic geofencing. We co-designed this prototype platform with community input, thereby incorporating user feedback. We outline a flexible approach that recognizes conflict complexity and user community heterogeneity. Here, we describe the evolution of an innovative Information and Communication Technologies-based alert system that enables instant data processing and community participation through interactive interfaces on different devices. We highlight the importance of a trans-disciplinary co-design and development process focussing on community engagement while synthesising expertise from ethnography, ecology, and socio-informatics. We discuss the bio-geographic, social, and technological variables that influence alert system efficacy and outline opportunities for wider application in promoting coexistence and conservation.

Guerilla Warfare and the Use of New (and Some Old) Technology: Lessons from FARC's Armed Struggle in Colombia

Schlagwörter: a-paper; appropriation; infrastructure; political conflict; war
Abstract Links

Studying armed political struggles from a CSCW perspective can throw the complex interactions between culture, technology, materiality and political conflict into sharp relief. Such studies highlight interrelations that otherwise remain under-remarked upon, despite their severe consequences. The present paper provides an account of the armed struggle of one of the Colombian guerrillas, FARC-EP, with the Colombian army. We document how radio-based communication became a crucial, but ambiguous infrastructure of war. The sudden introduction of localization technologies by the Colombian army presented a lethal threat to the guerrilla group. Our interviewees report a severe learning process to diminish this new risk, relying on a combination of informed beliefs and significant technical understanding. We end with a discussion of the role of HCI in considerations of ICT use in armed conflicts and introduce the concept of counter-appropriation as process of adapting one's practices to other's appropriation of technology in conflict.

Abstract Links

Women interested in computing are still facing several problems considering equality and career chances. Companies realize the opportunities of diversity and yet for several reasons they are struggling to hire or integrate young female professionals. Although gender study research provides promising frameworks there are still issues in applying them in working environments and practices. For this purpose, we made use of the Living Lab approach in the context of gender and IT. The Living Lab's methodology offers opportunities to reveal new, relevant insights and create social change in a collaborative way. We stretched the existing understanding of this concept and follow a Participatory Action Research approach. In this paper we describe the setup of the Living Lab and present first insights from our research. We found that showing patience, organizing adequate spaces for reflection as well as facilitating motivation and trust is vital in such a sensitive research context.

Abstract Links

Mobility assistance ICTs have become important companions in daily life as digital affordances have become sophisticated. However, understanding and researching everyday way-finding is still challenging, mainly because of the sheer difficulty of collecting empirical data about concrete occasions of use. Hence, we argue that those methodological challenges make it harder to understand the mobility needs of certain user groups. We aim to address this gap while focusing on elderly people, a user group that has increasingly become a focus of HCI studies, and ask the following questions: (1) What are the everyday way-finding practices of that user group? And (2) how can these be supported by mobility assistance ICTs? For answering them, we developed a methodological framework to study daily mobility as way-finding practices and conducted an interview study with 15 ‘young elderly' people supplemented with a probing technique. The paper concludes with reflections on the potential for and limits to, the study of, and designing for, way-finding as practices.

Abstract Links

Introduction Frailty increases the risk of poor health outcomes, disability, hospitalization, and death in older adults and affects 7%–12% of the aging population. Secondary impacts of frailty on psychological health and socialization are significant negative contributors to poor outcomes for frail older adults. Method The My Active and Healthy Aging (My-AHA) consortium has developed an information and communications technology–based platform to support active and healthy aging through early detection of prefrailty and provision of individually tailored interventions, targeting multidomain risks for frailty across physical activity, cognitive activity, diet and nutrition, sleep, and psychosocial activities. Six hundred adults aged 60 years and older will be recruited to participate in a multinational, multisite 18-month randomized controlled trial to test the efficacy of the My-AHA platform to detect prefrailty and the efficacy of individually tailored interventions to prevent development of clinical frailty in this cohort. A total of 10 centers from Italy, Germany, Austria, Spain, United Kingdom, Belgium, Sweden, Japan, South Korea, and Australia will participate in the randomized controlled trial. Results Pilot testing (Alpha Wave) of the My-AHA platform and all ancillary systems has been completed with a small group of older adults in Europe with the full randomized controlled trial scheduled to commence in 2018. Discussion The My-AHA study will expand the understanding of antecedent risk factors for clinical frailty so as to deliver targeted interventions to adults with prefrailty. Through the use of an information and communications technology platform that can connect with multiple devices within the older adult's own home, the My-AHA platform is designed to measure an individual's risk factors for frailty across multiple domains and then deliver personalized domain-specific interventions to the individual. The My-AHA platform is technology-agnostic, enabling the integration of new devices and sensor platforms as they emerge.

Of Embodied Action and Sensors: Knowledge and Expertise Sharing in Industrial Set-Up
In: Computer Supported Cooperative Work (CSCW), Volume: 27 No.:3, S. 875-916, DOI: 10.1007/s10606-018-9320-6
Abstract Links

Knowledge and expertise sharing has long been an important theme in CSCW and, importantly, one that has frequently challenged a prevailing view concerning knowledge management. This critique focused, initially, on the practical problems associated with issues of Organisational Memory (OM), and in particular the difficulties inherent in an oversimplified ‘repository’ model. Attention then turned to issues of contextuality and communication for expertise sharing, drawing on concepts such as communities of practice and social capital to understand, again, the sharing of knowledge and expertise in practice. Here, we report on how particular kinds of ‘embodied action’ can be identified in relation to the potential of cyber-physical infrastructures for knowledge sharing in an industrial context. We argue that, in a complex industrial domain, both the recording of physical movement – ‘showing’ – and the representation of local knowledge – ‘telling’ – are potentially relevant. Our proposal is that the evolution of cyber-physical infrastructures now offers a way of changing some early assumptions about how knowledge might be captured and displayed. We argue that we are entering a third generation of knowledge and expertise sharing research, where the use of augmented reality (AR) and sensor technology will result in significant new methodological innovations, including the capture and sharing of knowledge, embedded in embodied action.

What happened in my home?: An End-User Development Approach for Smart Home Data Visualization
Schlagwörter: a-paper; PRAXLABS; SMARTLIVEAbstract

Smart home systems change the way we experience the home. While there are established research fields within HCI for visualizing specific use cases of a smart home, studies targeting user demands on visualizations spanning across multiple use cases are rare. Especially, individual data-related demands pose a challenge for usable visualizations. To investigate potentials of an end-user development (EUD) approach for flexibly supporting such demands, we developed a smart home system featuring both pre-defined visualizations and a visualization creation tool. To evaluate our concept, we installed our prototype in 12 households as part of a Living Lab study. Results are based on three interview studies, a design workshop and system log data. We identified eight overarching interests in home data and show how participants used pre-defined visualizations to get an overview and the creation tool to not only address specific use cases but also to answer questions by creating temporary visualizations.

Abstract Links

What is end-user development (EUD) and when does a user become an end-user developer? Since the concept of EUD encompasses methods as well as practices of appropriating technology, it is not easy to answer these questions and several researchers already dealt with these issues. Within our chapter we suggest to conceptually extend our understanding of both EUD and the end user (developer). We draw on experiences we gained from past research exploring EUD in practice. We reflect upon the concepts of “gentle slope of complexity,” “tailoring languages” and “appropriation” which we situate within the broader concept of “infrastructuring.” We claim that EUD is given whenever an end user starts modifying the permanent aspects of an application (soft- or hardware) and, thus, starts climbing the tailorability mountain – or in our words, the tailorability staircase – and switching to a higher level to perform a specific practice. In our newly developed terminology this very moment, called “point of infrastructure,” is characterized by a break-down in the current practices which leads an end user to becoming an end-user developer.

Abstract Links

The amount of data being available is increasing rapidly. Based on the technological advances with mobile and ubiquitous computing, the use of social media is getting more and more usual in daily life as well as in extraordinary situations, such as crises. Not surprisingly, this increasing use is one reason why data on the internet is also developing that fast. Currently, more than 3 billion people use the internet and the majority is also registered with social media services such as Facebook or Twitter. While processing this kind of data by the majority of non-technical users, concepts of End-User Development (EUD) are important. This chapter researches how concepts of EUD might be applied to handle social big data. Based on foundations and an empirical pre-study, we explore how EUD can support the gathering and assessment process of social media. In this context, we investigate how end-users can articulate their personal quality criteria appropriately and how the selection of relevant data can be supported by EUD approaches. We present a tailorable social media gathering service and quality assessment service for social media content, which has been implemented and integrated into an application for both volunteers and the emergency services.

Schlagwörter: design case study; grounded theory; IS design research; praxeology; socio-technical systems
Abstract Links

In this paper, we propose Grounded Design - a particular design research (DR) approach rooted in a practice-theoretical tradition. It assesses the quality of information technology (IT) design through evaluation of emerging changes in social practices, which result from the appropriation and use of IT artifacts. The paper starts with a systematic analysis of the reasons for persistent limitations of traditional information systems DR, specifically in coping with problems of contingency and self-referentiality. Following this critique, the principles of Grounded Design are presented. Grounded Design is applied in case studies where we reconstruct the social practices observed before and during the design and appropriation of innovative IT artifacts. We call these context-specific research endeavors ‘design case studies.’ In conducting these case studies, Grounded Design builds upon well-established research methods such as ethnographical field studies, participatory design and action research. To support the transferability of its situated findings, Grounded Design suggests documenting increasing numbers of design case studies to create an extended, comparative knowledge base. Comparing cases allows for the emergence of bottom-up concepts dealing with the design and appropriation of innovative IT artifacts in social practice.

3D printing has 1 become an area of intense interest in many disciplines ranging from industry through education, humanitarian and innovation contexts to research. At the same time, technologies, materials, usages and appropriation are in constant flux. 3D printing is but one of the many facet of digital fabrication, the digitalization of more sectors, "Industry 4.0" and increasing community-based innovation and (open/commons-oriented) engineering practices. This workshop is intended to illustrate and discuss cases, positions, concepts and experiences related to such developments in digital fabrication, especially in 3D printing. We specifically look for contributions highlighting the role of digital fabrication and 3D printing for the common good and the education sector. This is in line with C&T's socio-technical focus, research suggesting the immense potential in digital fabrication and education as well as growing practices in using digital fabrication/3D printing in humanitarian efforts.

Socio Informatics – A practice‐based perspective Proposed Table of Contents
Abstract Links

The book will propose a practice‐based approach to socio‐ informatics, a research paradigm in applied CS which suggests building a corpus of contextually situated design case studies. This practice‐based approach builds substantially on work in CSCW, but notably on the socio‐ technical approaches sometimes associated with European CSCW. Our position is that a major lacuna in CSCW thus far has been the absence of adequate means to deal with the problem of transferability of insight across different case studies. That is, although a growing corpus of studies has demonstrated the importance of socio‐ technical insights, conceptual and theoretical competition has restricted their value. We aim to begin the process of rectifying this situation by proposing a systematic approach to the problem of interdisciplinarity. The last twenty five years have seen a small revolution in our approach to the understanding of new technology. It has become a founding assumption of CSCW that in the future, if not already, most computer applications will be socially embedded in the sense that they will become infrastructures for the development of the social practices which they are designed to support. This will be true in an ever increasing variety of domains and living conditions. Assuming that IT artifacts have to be understood in this socio‐technical way, traditional design criteria in CS (performance, correctness, stability or usability) need to be supplemented by methods and perspectives which illuminate the way in which technology and practice are mutually elaborating. This has involved, inter alia, new methodologies for the investigation of patterns of use and the gathering of requirements (including ethnographic work; 'living labs' and so on); new methodologies for design (methodologies which place flexibility and user involvement at the centre) and new approaches to the product lifecycle (which recognize the complex and long term nature of appropriation of technology by users and hence implicate a different understanding of evaluation). Nevertheless, these developments remain piecemeal. In our view, the field has to a degree been restricted in its development by a competition between theoretical perspectives largely founded in their disciplinary origins in sociology and psychology. The growth of a systematic and rigorous approach to practice‐ based, or human‐centred, computing requires new foundations. These foundations, we suggest, will be predicated on the resolution of a number of issues: 1. A clearer understanding of what we mean by practice and how it is socially embedded. 2. A more nuanced view of the different ways in which processes of empirical investigation and of construction may be linked to each other. 3. A better understanding of the way in which new design methodologies link to investigative approaches and of effective mechanisms for supporting stakeholder involvement. 4. A systematic approach to the use of technology which extends from early investigation into domains of practice through to investigation of the ways in which practices become embedded in social and organizational life. Our proposal, then, is for an edited book structured to reflect these issues and concerns. More specifically, this will be done by linking key methodological chapters to empirical chapters which illustrate these themes. To elaborate on this, the book will be divided into four parts. The first one elaborates on the theoretical foundations of design‐related work, specifically on the concepts of practice, design and appropriation. In the second part, different methodological approaches and how best to utilize them in design‐related enquiry will be presented and discussed. Again, the focus will be on the tailoring of investigative strategies for specific kinds of design problem (business ethnography, grounded design, integrated organization and technology development, mobility, cross‐ cultural work, inter‐organizational collaboration). The third part presents a sample of design case studies originated in different social and organizational contexts which can be understood as exemplars of more general problems. That is, each will orient in turn to the problem of comparability and ways in which cross‐cutting issues can be identified. Design case studies are understood as investigations into the practices before and after introducing the IT artifacts and the design process in support of these practices. They develop on a three phase research model, linking: empirical prestudy, the IT design and the investigation into its appropriation. We argue that design case studies or fractals of them should become a key element in Socio Informatics. In this sense, 'Socio Informatics' is epistemologically distinct from traditional approaches to CS in the sense that it creates highly context specific results and its findings are only valid in the context of their emergence. CS and even the traditional approaches to Human Centered Computing assume a context‐independent validity for these formal, algorithmic and design‐oriented findings. If research‐ findings are context‐specific we need to find new ways to reason about their transferability.

Abstract Links

The current understanding of `Industry 4.0' often includes the vision of a fully-automated and technology-driven development of the German industry. But the practical configuration of such a vision is not an appropriate option for small and medium companies, which are the actual driver of the German economy. Especially for smaller and medium sized companies, the own staff, as well as their experiences and work capacity decisively secure the economic success and need to be put in the spotlight of industrial 4.0 concepts and technologies. When considering the employee as one of the central factors of success within small and medium companies, the practical adaption of fully-automated and technology-driven concepts raise a variety of social issues, which need to be addressed by the social partnership, such as employer organizations, employee organizations as well as scientific partners. This article presents the current social issues as well as areas of conflict in which these social issues are settled. Such issues were collected on the basis of an expert workshop with managers and business consultants of small and medium companies and various interviews with representatives from the labor union IG Metall and the employers' associations in regard to the change of work in the context of `Industry 4.0'.

Zusammenfassung Das aktuelle Verständnis von Industrie 4.0 umfasst oftmals die Vision einer vollautomatisierten und Technologie-determinierten Entwicklung der deutschen Industrie. Eine praktische Ausgestaltung einer solchen Vision bietet dabei keine hinreichende Option für den Mittelstand – den eigentlichen Treiber der deutschen Wirtschaft. Speziell bei kleineren und mittelständischen Unternehmen sichern die eigenen Mitarbeiter/innen sowie deren Erfahrungen und Arbeitsver-mögen maßgeblich den wirtschaftlichen Erfolg und müssen bei der Ausgestaltung von Industrie 4.0-Konzepten und -Technologien in den Fokus gerückt werden. Bei 72 T. Ludwig et al. 1 3 der Betrachtung der Mitarbeiter bzw. der Mitarbeiterinnen im Zentrum des Mittel-standes, fallen bei der praktischen Ausgestaltung von Industrie 4.0 eine Vielzahl sozialer Fragestellungen an, welche vor allem aber im Betrieb von Unternehmen und Betriebsrat bearbeitet und sozialpartnerschaftlich ausgestaltet werden müssen. In diesem Artikel werden die aktuellen Spannungsfelder präsentiert, in welchen die sozialen Fragestellungen angesiedelt sind. Diese wurden auf Basis eines Experten-workshops mit Geschäftsführern und Unternehmensberatern kleiner und mittelstän-discher Unternehmen sowie durch verschiedene Interviews mit Vertretern der IG Metall im Hinblick auf die Veränderung von Arbeit im Kontext von Industrie 4.0 erhoben.

Social media usage during the recent uprisings in Arabian countries has gained increasing attention in CHI research. This study adds to these insights by providing some findings on the use of ICT, specifically mobile media, by opposition forces and political activists during the Syrian civil war. The presented study is based on 17 interviews with Syrian FSA fighters, oppositional activists and refugees. A first analysis showed evidence for some very specific use patterns during wartime (compared to media usage of political activists under less anomic conditions). The study also describes a fragmented telecom infrastructure in today's Syria: government-controlled regions offer fairly intact infrastructures while rebel-controlled regions are cut-off from telephone and internet. Moreover, the central and very critical role of mobile video for documenting, mobilization, and propaganda is discussed.

Living Labs provide a human-centric' research approach for the design of new ICT artefacts. In Living Labs users participate over several design stages, providing insights into unexpected ICT use, co-creation and evaluation of new IT solutions. Although this approach is becoming more popular, there is little comparative and reflective work on its practical dynamics, problems and possibilities. In this study, we analyse two 4-year Living Lab projects in Lancaster, UK and Siegen, Germany within the domain of Social TV, and compare experiences. We focus on documenting the purposes, methods and user dynamics that affect the trajectory of such long-term research initiatives, focusing inter alia on the dynamics of researcher/user interaction and the developing issues of trust and managing expectations; emphasizing some often neglected ethical issues and the impact of users' individual characteristics and their role in the community dynamics of Living Labs.

Abstract Links

This paper contributes to the current discourse on practicebased research in HCI paying particular attention to the overall temporal and situational conditions which frame an R&D project. We present a Living Lab study situated in an arbitrary neighborhood of a German city which develops ICT support to foster informal help and social interaction with a special, but not exclusive, focus on elderly tenants. We demonstrate that practice-based, long-term research in a city quarter goes beyond those challenges already described in the current Living Lab and PD literature. The long-term study's positioning in a real-world context is contoured not only by a high diversity of stakeholders and their individual interests and motivation for participation but also by their individual skill sets and learning needs. These distinct and often contradictive perspectives have to be permanently counterbalanced. Thus attention has to be focused on how related strategies and decisions impact on the design of the project as well as on the final ICT product. To enable all tenants, irrespective of age and technical skill, to participate in a long-term ICT-based community development project, we applied the format of ‘experience-based PD workshops' to foster confidence in ICT usage and encourage the competency of the elderly and non-tech-savvy tenants.

Abstract Links

The introduction of IT has changed the way we live in many ways. Historically, it can even be argued that socially embedded applications of information technology challenge and change practices to an extent rarely seen before with any other type of technological artefacts. If these IT artefacts have strong and recurrent impacts on people's lives, we need to reconsider design practice artefacts which allow for anticipating use practices and bring together inspirational creativity with evaluative methods. Approaches such as Participatory Design (Greenbaum and Kyng 1991) and User‐Driven Innovation (von Hippel 2005) have already significantly increased the level of involvement of users and their fields of practice into IT development and have strengthened the role of ethnographic methods as well as the importance of methods providing direct user feedback. But even a strong component of domain analysis or user participation does not warrant an accurate anticipation of the changes in social practices resulting from new technological artefacts or infrastructures. Moreover, the immaterial nature of software contributes to its application beyond the originally intended context. The material and social foundations of IT usage have significantly changed over the past two decades. Technologically, the standardization of communication interfaces, the increase of bandwidth and speed of internet connections and their ubiquitous availability have connected more and more devices with each other. At a social level this has also created stronger connections between professional and private domains and practices, offering new room to adapt these practices and re‐negotiate their relations and compositions. These developments have made us now look at ecosystems (Draxler et al. 2015) or infrastructures (Star and Ruhleder 1996) of technology‐based practices. With regard to methods, EUSSET's research agenda would benefit from a convergence of a broadly defined research program which looks at technology development as well as scenarios of usage and accumulates results in various ways, bridging the gap between a simple ‘technology‐in‐practice' perspective and a ‘technology‐based practice change' perspective. We need to consider how to carefully transfer emerging design concepts, IT artefacts, and pattern of appropriation derived in a specific context to other fields of application. We also need to better understand how to transfer findings gained with the design and appropriation of one artefact towards that of another, related one. In this paper we will outline a research program, called practice‐based computing, which suggests collecting a corpus of highly contextualized design case studies and supports the transferability of insights by comparative concept building on top of these cases.

Come_IN computer clubs are an established approach to support inter-cultural and inter-generational learning in German neighborhoods. We explore the adaptation of the come_IN concept to the Palestinian context as a means to bridge the social and economic divide that has plagued West Bank society for a period of more than six decades. Social exclusion, political conflicts and prolonged military occupation have kept the refugee camps in a perpetual state of marginalization. In this paper we report on our work in Al Amari – a Palestinian refugee camp adjacent to the city of Ramallah. We examine how the computer club enables the emergence of social ties among residents of the camp and university students acting as tutors. Even though the ties are small-scale and informal, they have the potential to generate new and wider opportunities for exchange that may eventually support more social integration between the camp's marginalized population and the wider Palestinian population.

EmergencyMessenger: A Text Based Communication Concept for Indoor Firefighting
In: Proceedings of the 32Nd Annual ACM Conference on Human Factors in Computing Systems, S. 1515–1524, DOI: 10.1145/2556288.2557188
Abstract

Finding and rescuing missing or injured people or fighting fire inside burning buildings is a central challenge for fire brigades. To ensure the safety of indoor work, monitoring the operations of firefighting units is crucial. As in most countries, firefighters in Germany utilize radio sets to establish voice communication between indoor operating units and the supervisory structure outside. Based on findings from a long term ethnographic study in cooperation with different German fire brigades over a time span of more than 5 years we analyzed the advantages and disadvantages of the current voice over radio communication tactics and techniques. We designed and evaluated a complementary text based communication device the EMERGENCY-MESSENGER to support the time critical work of indoor units working under harsh conditions, wearing Self-Contained-Breathing-Apparatus (SCBA). We conducted 13 full scale training missions including extensive debriefings to design and evaluate the communication concept and the corresponding device.

Abstract Links

The high complexity of knowledge-intensive work such as software development makes it beneficial to have spaces for formal and informal articulation work. Existing information systems (IS) tend to treat these different aspects of coordination separately, resulting in problems of awareness and coordination. To bridge this gap, we present the concept of Articulation Spaces which combines aspects of Coordination Mechanisms and Common Information Spaces (CIS) in order to provide a room for mediating between the formal and informal aspects of coordination. Based on a design study in the form of a lightweight public display that has been tested in a medium-sized German software company, we show how Articulation Spaces provide information for meta-coordination, encourage ad-hoc coordination and support decision-making processes. Our findings provide insights into the design of support systems for flexible and coordination-intensive contexts such as software development work. Copyright © 2014 ACM.

Schlagwörter: design; dynamic ridesharing; elderly; ethnography; social experiences
Abstract Links

Alternative mobility modes for older adults are increasingly important for economic, ecological and social reasons. A promising option is ridesharing, defined as use of the same vehicle by two or more people traveling to a common destination. In particular, mobile computer supported ridesharing provides a promising way to enlarge older adults' mobility choices in addition to private driving and public transportation options. In order to understand the opportunities and obstacles of ridesharing from the point of view of elderly people, we conducted an interview study in order to examining ridesharing experiences. It turns out that "mobile independence" and "decisional autonomy" are key issues for mobile wellbeing. This partially conflicts with common ridesharing concepts. Hence, we further analyze older adults' strategies dealing with these conflicts and show that these strategies offer departure points for the design ridesharing solutions, which are better suited to the demands of older adults.

Abstract Links

One of the great societal challenges that we face today concerns the move to more sustainable patterns of energy consumption, reflecting the need to balance both individual consumer choice and societal demands. In order for this ‘energy turnaround' to take place, however, reducing residential energy consumption must go beyond using energy-efficient devices: More sustainable behaviour and lifestyles are essential parts of future ‘energy aware' living. Addressing this issue from an HCI perspective, this paper presents the results of a 3-year research project dealing with the co-design and appropriation of a Home Energy Management System (HEMS) that has been rolled out in a living lab setting with seven households for a period of 18 months. Our HEMS is inspired by feedback systems in Sustainable Interaction Design and allows the monitoring of energy consumption in real-time. In contrast to existing research mainly focusing on how technology can persuade people to consume less energy (‘what technology does to people'), our study focuses on the appropriation of energy feedback systems (‘what people do with technology') and how newly developed practices can become a resource for future technology design. Therefore, we deliberately followed an open research design. In keeping with this approach, our study uncovers various responses, practices and obstacles of HEMS use. We show that HEMS use is characterized by a number of different features. Recognizing the distinctive patterns of technology use in the different households and the evolutionary character of that use within the households, we conclude with a discussion of these patterns in relation to existing research and their meaning for the design of future HEMSs.

The Challenges of Microfinance Innovation: Understanding ‘Private Services’

Abstract

The organization, technology and operation of microfinance have undergone much change and differentiation. Muhammad Yunus, a Nobel-prize winner first demonstrated the possible empowerment of poor people by means of microfinance. Even so, certain cases have indicated that this empowerment does not necessarily occur and that microfinance can even be damaging. In this paper, we describe a case study which describes some of the value clients do receive from an initiative of this kind but notes that this value sometimes lies in unofficial, ‘private’, advice and help. To this end, we conducted an ethnographic study in a microfinance institution (MFI) in Azerbaijan. We found a special pattern of interaction between MFI-staff members and customers, which both regarded as beneficial. Since, from the point of the organization, it was not recognizably part of their work, we call it a “private service”. We think that the identification of similar private initiatives may help to identify new possible synergies between the operation, organization and technology in the microfinance sector. All of them are decisive for the identification of promising human–computer interaction patterns and the design of supportive computer applications.

Schlagwörter: a-paper; PRAXLABS; Energy literacy; Energy monitoring; HEMS
Abstract Links

This paper presents results of a three-year research project focused on the emplacement of Home Energy Management Systems (HEMS) in a living lab setting with seven households. The HEMS used in this study allowed householders to monitor energy consumption both in realtime and in retrospective on the TV and on mobile devices. Contrasting with existing research focused on how technology persuades people to consume less energy, our study uses a grounded approach to analyze HEMS emplacement. As an important result, we present here the issue of 'energy literacy'. Our study reveals that, by using HEMS, participants became increasingly literate in understanding domestic electricity consumption. We discuss the role HEMS played in that process and how the acquired literacy changed energy consumption patterns. We conclude that literacy in energy consumption has value on its own and explain how eco feedback system designs can benefit from this understanding. Copyright © 2013 ACM.

Abstract

Mädchen und junge Frauen waren und sind in der Informatik unterrepräsentiert. Das Phänomen hat tiefliegende Ursachen, die sich von der Wahl des Schulfachs über Ausbildungs- und Studienwege schließlich bis auf berufliche Karrieren erstrecken. Auf der Grundlage qualitativer empirischer Arbeiten an drei deutschen Gymnasien wurde ein Informatik-Curriculum entwickelt und praktisch erprobt, das seine informatischen Inhalte direkt mit professioneller, selbstständiger Tätigkeit in der IT-Branche verknüpft. Die erste praktische Durchführung hat gezeigt: der Projektcharakter der Lehre, die informatische Lerninhalte und professionelles Arbeiten direkt mit Karrierewegen im Bereich IT verknüpft, kann das Interesse von Mädchen für Informatik und die IT-Branche positiv beeinflussen; insbesondere die Möglichkeit, im Sinne des End-User-Developments selbst gestalterisch aktiv zu werden, wirkt motivierend. Leitfadengestützte, halb strukturierte Interviews mit den Mädchen und Informatiklehrern und -lehrerinnen an den drei beteiligten Schulen, nicht-teilnehmende Beobachtung des Informatik-Unterrichts sowie Design-Notizbücher und im Rahmen der curricularen Projektarbeit erstellte Artefakte bilden die Datengrundlage der hier vorgestellten Studie.

Schlagwörter: arab spring; on the ground' studies; social media
Abstract Links

We present a study conducted in Sidi Bouzid, the Tunisian town where the Arab Revolution, also known as 'Arab Spring', started, and where the role of Web 2.0 and social media applications in the people's uprising have been much discussed. We identify four relevant phenomena: (1) the publication of classified materials via WikiLeaks challenged the regime's legitimacy, (2) Web 2.0 connected local activists with Arab satellite TV, (3) social media linked the young activists with actors in other cities in Tunisia, (4) social media allowed organizing resistance inside Sidi Bouzid. Methodologically, we question a too deterministic view of the role of the new media and the representativeness of investigative techniques that uniquely use the new media in order to assess their impact. At the same time, rigorous investigations 'on the ground' are extremely difficult. We present a modest and initial attempt to provide such an 'on the ground' approach, cognizant of necessary limitations. We compare our findings with studies which analyze data downloaded out of social media applications and suggest that studies of the kind we describe offer additional insight and play an essential role in better understanding political uses of social media.

New Technology @ Home : Impacts on Usage Behavior and Social Structures
S. 185–194
Schlagwörter: diary study; living lab; living room; LivingLabEnergy; media usage; PRAXLABS; television
Abstract

Studying domestic usage contexts has become an important field in research. Recent technological improvements have made media available on different devices, in different contexts and from different places. The adoption and appropriation of new devices and technologies has led to a more flexible usage behavior. However, even if we know about such a behavior, many questions, regarding how new technology changes the user's media usage and how these changes affect the social structure in a household, are still unanswered. We will address this topic in our work and want to provide an insight on how recent media consumption patterns have changed due to the appropriation of new technologies in the home. Based on a qualitative long-term Living Lab study we will present various patterns based on changes in media usage routines and their influences on households as social systems. The results provide a detailed understanding of how the new technology is embedded within domestic life by considering potentials and conflicts that also address further design oriented work.

Abstract Links

Adaptations of business processes are important in work environments, specifically when process-support needs to be tailored according to changing needs. The creation, management, and adaptation of the process models require typically modeling-experts. While these actors are knowledgeable in formalizing and operationalizing processes end-users who do not necessarily possess sophisticated modeling skills know typically local practices and framing conditions best. In this paper, we present an approach to support users in articulating their needs and to involve them into the (re-)design of process specifications. We explore how end-users reflect upon and articulate about business processes. Based on results of a qualitative study, we present a new, paper-based interaction technique, which enables users with little skills to model processes. The resulting process specifications can be transferred either in paper or in digital form into traditional modeling systems for further elaboration.

HCI public policy activities in 2012
In: Interactions, Volume: 19 No.:3, S. 78, DOI: 10.1145/2168931.2168947
Abstract Links

These HCI issues affect the core activities of many HCI researchers or practitioners: interface design, user testing and research, and funding. The challenges exist in every country, yet the solutions, and the knowledge to lead to solutions, are international. As an HCI community, we must be proactive, not reactive. We want to be involved from the beginning so that policymakers trust us and so that our research and practitioner expertise can influence public policy. The worst situation is to be reactive-to see policies created and then decry them as ineffective, not having been involved with their creation. Proactive involvement has much more of an impact. As a start, HCI researchers should become familiar with the process of how public policies are created in their national and regional governments. For researchers interested in data, science, and statistics, this is often not something that comes naturally. The HCI community has a long history with the process of user-centered design, in which we say that user data needs to influence design. Great. So let's take those same concepts and apply them to public policy. We need to use our research, our data, and our design expertise to help drive public policy- those things should drive policy, not politics or public opinion. To be effective, we need to be proactive, we need to get involved, and we need to work together internationally. © 2012 ACM.

Abstract

Indoor navigation plays a central role for the safety of firefighters. The circumstances in which a firefighting intervention occurs represent a rather complex challenge for the design of supporting technology. In this paper, we present the results of our work designing an ad hoc ubicomp infrastructure to support navigation of firefighters working in structure fires inside the zone of danger. We take a wider approach, complementing the technical questions with the development of effective navigation practices based on technology available today. We provide an overview of the complete design process, from the theoretical and empirical underpinnings to the construction and evaluation of three iterations of the platform. We report the results of our evaluation and the implications and tensions uncovered in this process, and we discuss the challenges and implications of it for the design of ubicomp for firefighters.

Analyzing political activists' organization practices: Findings from a long term case study of the european social forum

Abstract

Designing ICT support for transnational networks of social activists is a challenge due to diverse organizational structures, cultural identities, political ideologies, and financial conditions. In this paper we present empirical findings on ICT usage in the organizing process of the European Social Forum (ESF) covering a period of almost 3 years. The European Social Forum is a platform for political activists involved in the anti-globalization movement. During our data collection period, the 5th and 6th European Social Fora were held in Malmo (2008) and Istanbul (2010). The paper describes complex social practices in organizing ESF events. We use the term fragmented meta-coordination to denote this type of practice. Mundane IT applications, such as a mailing list and a content management system, play a central role in enabling different aspects of fragmented meta-coordination. The findings also indicate how lacking resources, organizational distribution, and technical limitations hamper the preparation process and reduce the transparency of political decision making. Our analysis highlights central organizational and technological challenges related to ICT appropriation in transnational networks of social activists.

Conducting ICT research in voluntary organizations: reflections from a long term study of the European Social Forum
In: Journal of community informatics, Volume: 7 No.:3
Schlagwörter: Economics; Ethnograph; Field work; Social networks
Abstract Links

Recent literature highlights the low technology adoption of voluntary organizations in their organizational settings. Due to the social importance of this sector, it is important that universities and researchers carry on action research projects in such settings to improve IT usage. These organizations are quite diverse in their organizational structure, scope, application area and working. Furthermore, they differ from traditional organizations in their objectives, rationale, operations and work practices. Appropriate technology design requires a deep understanding of organizational work practices, paving the way for ethnographic action research studies in these settings. In this paper, we want to present our experiences with conducting an ethnographic action research at the European Social Forum, which is a European network of heterogeneous social activists participating in the anti-globalization movement. We will discuss the problems that we faced in our fieldwork to help other researchers comprehend these difficulties in advance as they are planning fieldwork in such settings.

Abstract Links

Located in socially and culturally diverse neighborhoods, we have built a network of intercultural computer clubs, called come-IN. These clubs offer a place to share practices among children and adults of diverse ethnical backgrounds. We show how this initiative ties into the striving for the integration of migrant communities and host society in Germany. In this paper, we analyze how collaborative project work and the use of mobile media and technologies contribute to integration processes in multicultural neighborhoods. Qualitative data gathered from interviews with club participants, participative observation in the computer clubs, as well as the analysis of artifacts created during project work provides the background needed to match local needs and peculiarities with (mobile) technologies. Based on these findings we present two approaches to add to the technological infrastructure: (1) a mesh-network extending the clubs into the neighborhood and (2) a project management tool, which supports projects and stimulates the sharing of ideas among projects. © 2011 Elsevier Ltd.

Abstract

News reports of Internet-based security breaches, identity theft, fraud, and other dangers may increase the perceived risk and decrease the perceived benefits of using electronic services (or e-services). We examine whether interactivity serves as a means to diminish the perceived risks and increase the perceived benefits of using e-services. To examine interactivity‟s influence on consumers‟ perceptions, we conducted a laboratory experiment using a simulated web-based, online payment system. When compared to a non-interactive preview of an online payment system, we found that consumers who used an interactive e-service simulation reported higher perceived involvement and authenticity as well as higher intangibility and risks of e-services. Further, we found that interactivity moderated relationships such that consumers were more likely to report higher intentions to use e- services. The paper concludes with implications for research and practice

Abstract

Der Beitrag befasst sich mit der theoretischen Fundierung der zweckmäßigen Gestaltung von Informa- tionssystemen. Er trägt zu einem internationalen Diskurs bei, der durch eine grundlegende Arbeit von Hevner et al. (2004) angestoßen wurde. Allerdings wirft deren Perspektive begriffliche und theoreti- sche Schwierigkeiten auf, die in einer eingeschränkten Rezeption pragmatischer Weltsicht wurzeln, auf die sich die Autoren berufen, und die ein unzureichendes Verständnis der Gestaltungsaufgabe zur Folge haben. Abhilfe lässt sich durch eine Erweiterung des theoretischen Rahmens gewinnen, der nicht nur die zu gestaltenden IT-Systeme, sondern vor allem auch deren Wechselwirkungen mit den sozialen Praktiken, die sie modellieren und im Gebrauch zugleich strukturieren, in den Blick nimmt. Diese ontologische und epistemologische Öffnung der Perspektive der Gestaltungswissenschaft hat methodi- sche Konsequenzen, die exemplarisch für die kanonische Aktionsforschung und Unternehmens- Ethnografie als aussichtsreichen neuen Vorgehensweisen erläutert werden. 1

Abstract

Recent literature has highlighted that most civil society organizations lack IT appropriation in their work practices. There is strong need to focus on this application area to empower these organizations by IT capabilities. As there is not much literature about the specific needs assessment of voulantary organizations, there is a need to carry out ethnographic studies to better understand IT requirements of this sector. In this paper we have investigated the organizing process of the World Social Forum 2006 event in Karachi, Pakistan. World Social Forum is an important gathering of social movements and voulantary organizations across the globe, and organizing such an event requires extensive communication and effective planning skills. The objective of this paper is to highlight the need and importance of this research issue. Our intention is to introduce appropriate technology in the organizing process to facilitate social activists. © 2010 Springer-Verlag.

Abstract

As voulantary organizations are differnt from business and governmental organizations in terms of structure, working methodologies and decision making, we are interested in the specific IT requirements and technology use in this sector. In this paper we investigate the Pakistani civil society sector to analyze the involvement of technology in their work settings. The paper also discusses two successful virtual voulantary organizations to highlight the potential of new media. The findings suggest that lack of technological and financial resources hinder them to adopt innovative solutions. The technological use is mostly limited, but the realization of its importance and urge to establish ICT infrastructures exist. So there is need for appropriating technology so that this sector in collaboration with government institutions can serve the public in a better way in new knowledge society. © 2010 Springer-Verlag.

Knowledge Management in Distributed Software Development Teams - Does Culture Matter?
In: 2009 Fourth IEEE International Conference on Global Software Engineering, S. 18–27, DOI: 10.1109/ICGSE.2009.10
Schlagwörter: Artos
Abstract

Software development requires complex context specific knowledge regarding the particularities of different technologies, the potential of existing software and the needs and expectations of the users. Hence, efficient knowledge management counts amongst the most important challenges for software teams. In international teams, one of the most important issues regarding knowledge sharing is the impact of culture under different aspects: national, organizational and professional. There seem to be very few studies dealing with the issue of culture in regard to knowledge management practices in GSE. We want to contribute to the discussion by presenting case studies of small size software teams dealing with international software development in the context of offshoring. In doing so, we illustrate how cultural and social issues influence the way knowledge exchange is performed by analyzing several knowledge management practices, considering the role of meetings, artifacts and tools, knowledge brokers and mutual visits between sites.

Operational and Strategic Learning in Global Software Development - Implications from two Offshoring Case Studies in Small Enterprises
In: IEEE Software, S. 1–15, DOI: 10.1109/MS.2009.153
Schlagwörter: Artos
Abstract Links

Small to medium-sized software enterprises (SME) increasingly participate in offshoring activities. Detecting market niches and deploying highly flexible software development approaches are seen as key competitive abilities of SME. Therefore, it is of major importance to learn how offshoring affects these capabilities which are closely related to organizational learning. We present case studies from two German companies that engage in offshoring of software development. By comparing the cases with each other, we highlight the different structures the companies chose for their development work and how these structures were enacted in practice. Furthermore, we show how related practices affect strategic and operational aspects of Argyris et al.'s (1985) conception of single- and double-loop learning. Our case studies show that organizational learning is a problem for SME engaged in offshoring and that an inability for double-loop learning can even lead to failures in case of organizational restructuring.

Offshoring in kleinen und mittleren Unternehmen der Softwareindustrie
In: HMD. Praxis der Wirtschaftsinformatik, S. 92–100
Schlagwörter: Artos
Abstract

Um ihre Wettbewerbsvorteile nicht zu verlieren, sind kleine und mittlere Unternehmen (KMU) der Softwareindustrie beim Offshoring auf ein hohes Maß an Flexibilität angewiesen. Die häufig für Offshoring empfohlene Formalisierung der Softwareentwicklung ist daher für KMU nur mit Einschränkungen möglich. Um die praxis-relevanten Probleme deutscher KMU im Kontext von Offshoring besser zu verstehen, untersuchen wir diese mittels qualitativer empirischer Forschungsmethoden. Wir zeigen anhand einer Einzelfallstudie, dass KMU im Rahmen von Offshoring häufig gezwungen sind, ihren Offshore-Entwicklern mehr Autonomie einzuräumen, als ursprünglich gewünscht wurde. Die geografische Verteilung von Kompetenz und Wissen erfordert dabei ständige informelle Abstimmungsprozesse zwischen den Teams. Diese sogenannte Artikulationsarbeit kann - als Pendant zu formellen Formen von Koordination - offenbar durch formale Koordinationswerkzeuge (etwa Fehlerdatenbanken) unterstützt, aber nicht ersetzt werden. Für KMU der Softwareindustrie kann es daher beim Offshoring notwendig sein, auf ein synergetisches Verhältnis zwischen formeller Koordination und informeller Artikulationsarbeit zu achten, statt die Entwicklung einseitig zu formalisieren.

ICT support for transnational social movements and civil society organizations is an important field of research: not only due to the increased political importance of this sector in a globalizing world but also due to their organizational characteristics. Transnational social movement organizations are typically characterized by a lack of resources, an absence of formal hierarchical structures, and differences in languages and culture among the activists. In order to design appropriate technological support for social activists' communities, it is important to understand their work practices which widely differ from traditional business organizations. This paper investigates into the organizational practices of the European Social Forum, in particular its 2008 meeting in Malmo, Sweden. We describe organizational practices in preparing and conducting the event. Since the goal of our research is directed towards enhancing the capabilities of social movements by means of ICT, we focus particularly on the usage of ICT.

Abstract Links

Global software development has become an important issue for small and medium enterprises. However, the distinct requirements of SME are still not so well understood. In order to contribute to the discussion we present case studies in two small German software companies that engage in offshoring of software development to Eastern Europe. By applying Strauss' articulation work framework we show to what extent SME rely upon situated coordination practices in order to warrant their agility. These practices are applied during discussions in which the actors reflexively evolve problems and solutions from their distinct perspectives and work practices. Thereby they are closely related to formal and informal communication, which takes place both locally and between the different teams. Our findings further suggest that specialized tools for the support of situated coordination practices in terms of articulation work are not so common in practice.

Abstract

Sport is a domain full of movement-based interactions. These interactions typically have positive health effects as well as an impact on social bonding. We have investigated ways in which computer augmented devices can lead to new sport experiences and explored opportunities to combine physical activities with remote social bonding. Three prototypes have been implemented which showcase movement-based interaction in sports. “Breakout for Two” allows geographically distant users to play a physically exhausting ball game together. “{FlyGuy}” gives users a hang-glide experience controllable through body movement. “Push'N'Pull” uses isometric exercise equipment over a network to encourage users to complete a cooperative game whilst performing intense muscular actions. A comparison of these applications shows that such movement-based interaction in a networked environment allows players in different locations to achieve a work out and also to socialize. Based on these projects, we conclude with practical design implications for future Exertion Interfaces.

Abstract Links

The present paper presents a longitudinal study of the course 'High-tech Entrepreneurship and New Media'. The course design is based on socio-cultural theories of learning and considers the role of social capital in entrepreneurial networks. By integrating student teams into the communities of practice of local start-ups, we offer learning opportunities to students, companies and academia. The student teams are connected to each other and to their supervisors in academia and practice through a community-system. Moreover, the course is accompanied by a series of lectures and group discussions. In this paper we want to present our experiences and to reflect upon the design changes between the first and the second instance of the course. The evaluation of the course showed that the work on real-world problems and the collaboration in teams together with partners from start-up companies were evaluated as very positive, although design flaws, and cultural and professional diversities limited the success of the first instance in 2001. For the second course in 2002, the didactical design was improved significantly according to evaluation results, which brought evidence that the design changes resulted in better collaborative practices and more stable relationships between start-up companies and students. Furthermore, it was found that especially the differences in cultural background and different historical experiences between the two distinct groups of 'students' and 'entrepreneurs' might make processes of social identification more difficult and, therefore, successful community-building less likely'.

Abstract

Former immigrant workers from Turkey have settled down in Germany.$\textbackslashbackslash$nThey have established communities within German cities. However,$\textbackslashbackslash$nthey are confronted with unequal opportunities. Differences in access$\textbackslashbackslash$nand appropriation of computer technology may amplify the gap between$\textbackslashbackslash$nthe German Turkish minority and the mainstream society. We have tackled$\textbackslashbackslash$nthis problem by creating an intercultural computer club. This paper$\textbackslashbackslash$npresents results from this action research project in which we engaged$\textbackslashbackslash$nchildren of an elementary school and their parents. We conclude that$\textbackslashbackslash$nthe application of ICT in the club has to be analyzed carefully with$\textbackslashbackslash$nregard to the differing needs of its members. When applying ICT in$\textbackslashbackslash$norder to produce artifacts in cross-cultural project teams, specific$\textbackslashbackslash$nroles emerge, which are mainly defined by sub-group affiliation.$\textbackslashbackslash$nSince Turkish women face serious challenges in finding their socio-cultural$\textbackslashbackslash$nidentity, we have extended the club's concept by adding a women's$\textbackslashbackslash$ngroup.

Abstract

Ignoring the informal, non-canonical nature of knowledge sharing, including people's motivation, ability and opportunity to share knowledge, is one of the key causes of resistance to use knowledge-sharing tools. In order to improve knowledge sharing supported by information technology (IT), tools need to be embedded in the social networks of which it is part. This has implications for our knowledge on the design requirements of such socially embedded IT. The paper reviews tools that are designed for the purpose to foster social capital. We will then discuss what is needed for an IS design theory related to knowledge communities and how such a theory could incorporate social capital theory.Journal of Information Technology (2006) 21, 40–51. doi:10.1057/palgrave.jit.2000053 Published online 4 October 2005

Abstract Links

The research field of end-user development has evolved, during recent years, to a certain degree of internal structure, problem awareness and consistency. Both academia and industry have begun to consider it an important field for research and development. In order to let EUD research contribute to the Information Societies, research and development must continue in a consolidated and well-balanced way. This chapter provides an overview of major challenges, motivates why these challenges should be addressed with considerable effort to bring about an Information Society with empowered end-users, and finally discusses how these challenges should be translated into a concrete research and development agenda for the short- and mid-term future. Key words. tailorability, end user programming, flexibility, usability

Abstract Links

We think that over the next few years, the goal of interactive systems and services will evolve from just making systems easy to use (even though that goal has not yet been completely achieved) to making systems that are easy to develop by end users. By now, most people have become familiar with the basic functionality and interfaces of computers, but they are not able to manage any programming language. Therefore, they cannot develop new applications or modify current ones according to their needs.In order to address such challenges it is necessary a new paradigm, based on a multidisciplinary approach involving several types of expertise, such as software engineering, human-computer interaction, CSCW, which are now rather fragmented and with little interaction. The resulting methods and tools can provide results useful across many application domains, such as ERP, multi-device services (accessible through both mobile and stationary devices), and professional applications.Key words. tailorability, end user programming, flexibility, usability

End User Development: An Emerging Paradigm

Abstract Links

In a world that is not predictable, improvisation, evolution, and innovation are more than a luxury: they are a necessity. The challenge of design is not a matter of getting rid of the emergent, but rather of including it and making it an opportunity for more creative and more adequate solutions to problems. Meta-design is an emerging conceptual framework aimed at defining and creating social and technical infrastructures in which new forms of collaborative design can take place. It extends the traditional notion of system design beyond the original development of a system to include a coadaptive process between users and a system, inwhich the users become co-developers or co-designers. It is grounded in the basic assumption that future uses and problems cannot be completely anticipated at design time, when a system is developed. Users, at use time, will discover mismatches between their needs and the support that an existing system can provide for them. These mismatches will lead to breakdowns that serve as potential sources of new insights, new knowledge, and new understanding. This chapter is structured in four parts: conceptual framework, environments, applications, and findings and challenges. Along the structure of the chapter, we discuss and explore the following essential components of meta-design, providing requirements, guidelines, and models for the future of end-user development: (1) the relationship of meta-design to other design methodologies; (2) the Seeding, Evolutionary Growth, Reseeding Model , a process model for large evolving design artifacts; (3) the characteristics of unself-conscious cultures of design , their strengths and their weaknesses, and the necessity for owners of problems to be empowered to engage in end-user development; (4) the possibilities created by meta-design to bring co-creation alive; and (5) the need for an integrated design space that brings together a technical infrastructure that is evolvable, for the design of learning environments and work organizations that allow end-users to become active contributors, and for the design of relational settings in which users can relate, find motivations and rewards, and accumulate social capital. Key words. co-creation, design for change, design space, design time, domain-oriented design environments, Envisionment and Discovery Collaboratory, interactive art, open systems, SER model, social capital, underdesign, unself-conscious cultures of design, use time, value-feelings.

Component-Based Approaches to Tailorable Systems
In: End User Development SE - 6, S. 115–141, DOI: 10.1007/1-4020-5386-X_6
Abstract Links

Flexibility is one of the most striking features of modern software. As the idea of integrating components is easily understood by programmers as well as end users, component architectures seem to be very promising to serve as a technological basis. In this chapter we give an overview of our work in the last years. A component model called FLEXIBEANS has been designed with the special notion to develop highly flexible and tailorable applications. The FREEVOLVE platform then serves as an environment in which compositions can be run and tailored. The second part of the chapter deals with the development and evaluation of different tailoring environments in which end users can compose their own applications or tailor existing ones. Users tests showed that besides a coherent technical basis and a manageable visual tailoring environment, there is a need for additional support techniques. We discuss how techniques to support users' individual and collective tailoring activities can be integrated into the user interface. Key words. tailorability, platform, component architecture, user interface, collaborative tailoring, evalution.

Abstract Links

Bringing together human actors with similar interests, skills or expertise is a major challenge in community-based knowledge management. We believe that writing or reading textual documents can be an indicator for a human actor's interests, skills or expertise. In this paper, we describe an approach of matching human actors based on the similarity of text collections that can be attributed to them. By integrating standard methods of text analysis, we extract and match user profiles based on a large collection of documents. We present an instance of the ExpertFinder Framework which measures the similarity of these profiles by means of the Latent Semantic Indexing (LSI) algorithm. The quality of the algorithmic approach was evaluated by comparing its results with judgments of different human actors.

Abstract

This paper presents the concept and an empirical evaluation of the course "High-tech Entrepreneurship and New Media". The course design is based on socio-cultural theories of learning and considers the role of social capital in entrepreneurial networks. By integrating student teams into the communities of practice of local start-ups, we offer learning opportunities to students, companies, and academia. The student teams are connected to each other and to their supervisors in academia and practice through a community-system. Moreover, the course is accompanied by a series of lectures and group discussions. In this paper we present empirical findings and reflect on changes in the design of the course which took place between its first and the second instantiation. These design changes were based on the empirical evaluation of the first course and a deeper analysis of the role of social capital.

In this paper we describe the evolutionary design and implementation of a search tool for files in shared workspaces used within an off-the-shelf groupware product. The design is based on the assumption that a useful generic search tool must be highly tailorable, which is achieved by applying an innovative software architecture allowing the assembly of components during runtime. In order to understand people's searching methods in shared workspaces and to support the design, we employed interviews and workshops with users as well as a field test to understand the users' needs. During the design process we developed a series of prototypes that were then evaluated by office workers. Consequently, the process described and the lessons learned extend from searching in files as a case via tailorability of software as an answer to the resulting requirements to component architecture as a way to implement this tailorability. The results derived from the treatment of these interrelated aspects constitute the core and value of this paper.

Abstract

The concept of social capital, or the value that can be derived from social ties created by goodwill, mutual support, shared language, common beliefs, and a sense of mutual obligation, has been applied to a number of fields, from sociology to management. It is only lately, however, that researchers in information technology and knowledge management have begun to explore the idea of social capital in relation to their fields. This collection of thirteen essays by computer scientists, sociologists, communication specialists, economists, and others presents a multidisciplinary look at this particular intersection of information technology and social science and the need to adopt a sociotechnical perspective.For the most part the contributors take a positive view of the interplay of social capital, knowledge sharing, and community building. Some essays look at specific instances, including the on-line and face-to-face relationships of a community of athletes, the building of social capital among Iranian NGOs, and the Internet-based communities created by the open-source movement, while others discuss more general ideas of civic and personal communities. The last four essays examine computer applications that augment social capital, including topic- and member-centered communications spaces such as the Expert Finder and the Loops system and virtual repositories of knowledge such as the Answer Garden and Pearls of Wisdom.

Participatory research in the health sector is fraught with obstacles. In particular, choosing appropriate methods to involve the heterogeneous stakeholders in the health system can be difficult. Not only are time constraints and hierarchies between professional (and non-professional) healthcare actors a challenge, but also dealing with patients who may have different physical and psychological limitations. Accordingly, not all qualitative methods are applicable to all stakeholder groups. Limitations such as speech or visual impairments can make it difficult to participate in focus groups or design workshops. With a workshop at the European Conference on Computer-Supported Cooperative Work in 2024, we discussed experiences and lessons learned with participatory methods in the health sector. The workshop showed how different challenges were dealt with and thus opened up a space for reflection on participatory projects.

Building communities among software engineers: The ViSEK approach to intra- and inter-organizational learning
In: Advances in Learning Software Organizations, Volume: 2640 No.:Lso 2002, S. 25–33, DOI: 10.1007/b94220
Abstract Links

The paper presents the concepts of the Distributed Center of Competency in Software-Engineering (ViSEK): a German national initiative to encourage intra- and inter-organizational learning in the software industry. Taking a socio-cultural stance, learning is understood as enculturation in a community of practice. So community building becomes an important objective when fostering intra- and inter-organizational learning. The ViSEK-project encourages community building among software-engineers at three different levels: between leading research groups, between research groups and practitioners, and among practitioners from different small and medium size enterprises (SMEs). We describe two approaches for community building more in detail: (a) an internet portal which presents software engineering knowledge and offers functionality for community support, (b) a regional network of SMEs which stimulates learning among its members in the field of usability engineering.

Exploration environments - Concept and empirical evaluation

Schlagwörter: GCT; groups
Abstract

Abstract: The authors are addressing the issue of how to get users to learn a system quickly and well. they reference ISO 9241 part 10. One recommendation for single user systems is experimentation with functions - for example, by using undo, or by freezing the system at certain states that can be returned to. In multi-user environments these are not sufficient. Also in groupware, the user needs to know how a certain action effects the other users - what they see on their screens. The problem is magnified, the authors point out, when the systems are tailorable. For example, there are two types of functions: normal and triggered. They develop "exploration environments" as a method for users to learn groupware by experimentation. Earlier work identified a number of specific problems with learning groupware: 1. Effects are hard to understand if the user can only see their own perspective. 2. Tailorable functions have extra difficulty because there are so many different alternatives 3. Triggered problems even more of a problem because can't know if consequences are due to their actions or those of others. 4. Dififculties when first learning an application because don't know if something a disturbance caused by other. Ran an experiment, but with only two users, and one of them was the researcher. they found support for exploration environments in terms of increasing understanding and creating better and faster performances, but only if the users had some previous experience with computers.

Abstract

The design of the user interface plays a major role in encouraging users to tailor an application. This paper focuses on a particular design issue. The question is how to support users in finding those functions which allow tailoring of an application. An empirical investigation shows that this is a major problem when users try to tailor applications. In order to tackle this problem the concept of direct activation is developed, which simplifies the finding of a tailoring function at the moment a tailorable function needs to be modified. To evaluate the effectiveness of the concept of direct activation in supporting tailoring activities, the concept has been implemented and an evaluation study carried out. The results of this study support the assumption that direct activation eases tailoring activities. Finally, the potentials and limitations of this concept are discussed.$\textbackslashbackslash$nThe design of the user interface plays a major role in encouraging users to tailor an application.

Abstract

Zugriffskontrollsysteme für kooperative Arbeitsumgebungen zeichnen sich durch eine hohe Komplexität aus. Das führt zu Schwierigkeiten bei der Präsentation und Manipulation von Zugriffskontrollsystemen auf der Ebene der Benutzerschnittstelle. Das Problem wird zudem durch die in kooperativen Arbeitsumgebungen vorherrschende starke Dynamik verschärft. Dieser Beitrag stellt einen nutzerorientierten Ansatz vor, dessen grundlegendes Konzept auf Zugriffsregeln basiert. Das Konzept, bei dem Erlaubnisse oder auch Verbote durch Zugriffsregeln repräsentiert werden, wurde auf Basis einer Feldstudie entwickelt. Die Regeln haben einen Gültigkeitsbereich, der durch Faktoren wie Benutzer, Dokumente, Rollen und Zeitintervalle definiert wird. Wir beschreiben, wie dieser Ansatz implementiert und in einem kommerziellen Groupware-System integriert wurde. Abschließend werden die Resultate einer Evaluation des Prototypen auf Basis der thinking-aloud-Methode diskutiert.

Exploration environments: Supporting users to learn groupware functions
In: Interacting with Computers, Volume: 13 No.:2, S. 265–299, DOI: 10.1016/S0953-5438(00)00046-1
Abstract

Explorative learning plays a major role when users face new functionality. Nevertheless, the multi-user character of groupware makes explorative learning more difficult. Users are often unable to understand the way certain functions work because they cannot perceive the effects of the functions' execution. This problem gets more severe with tailorable groupware. Therefore, we propose exploration environments as an additional feature to support users in self-directed learning. Looking at three tailorable groupware tools, we show how exploration environments can be realized. To generalize our findings, we develop a model which describes the user interface of tailorable groupware. Based on this model, we compare the design of the three tools and present general guidelines for the implementation of exploration environments. Finally, we report about the results of a workshop in which a groupware tool containing exploration environments has been evaluated.

Tailoring Groupware for Different Scopes of Validity
In: Behaviour & Information Technology, Volume: 18 No.:3, S. 199–212, DOI: 10.1080/014492999119084
Abstract

Tailorability is generally regarded as a key requirement for groupware applications. In this paper, we will focus on a specific class of tailoring activities: the definition of different system behaviour for specific scopes of validity. Since the state of the art in the CSCW literature does not yet offer any satisfactory solutions to support users in performing this class of tailoring activities, we develop an approach based on tailoring statements, which are similar to production rules. We show how inconsistencies resulting from contradictory statements can be handled either automatically or by involving the affected users. We present a prototype, which implements our approach to tailorability in a commercial groupware system, using access control as an example for the proposed class of tailoring activities. Finally, we present the results of a usability test carried out which employs the thinking aloud method.

Abstract

During the summer semester 1997 five German universities participated in a telelearning pilot project where a telelecture and -tutorial was held via the internet. Within this pilot project, we evaluated the m-bone based video conferencing tool as well as the applied didactic concept. The video conferencing tool provided insufficient quality of transmission and was deficient regarding its functionality as well as its interface. Concerning the telelecture we found reduced attention of the remote participants, and a lower level of interactivity between lecturers and students. Positive feedback regarding the tutorials which tried to encourage interactivity among the participant and regarding newly didactic elements within the lecture indicate that telelearning requires new teaching and learning approaches to compensate for its obvious constraints.

Reducing conflicts in groupware: Metafunctions and their empirical evaluation
In: Behaviour & Information Technology, Volume: 15 No.:6, S. 339–351, DOI: 10.1080/014492996120021
Abstract Links

Certain functions in groupware affect more than one user who might have conflicting interests. To describe conflicts arising from the use of groupware functions, we distinguish the roles of the activator and the user affected. As technical means to lessen these conflicts, we develop two metafunctions: visibility of use and negotiability. We expect that these metafunctions reduce role-based conflicts and lead to higher acceptance of groupwaresystems among users. To examine these hypotheses we performed an empirical study in six different organizations. Using scenarios to present different design options to users, we confirmed most of our assumptions. Implications of these findings for the design of groupware are discussed. Certain functions in groupware affect more than one user who might have conflicting interests.

Abstract

1. Introduction Organizations face increasing complexity and dynamics of their environment. To cope with it organizational structures have to be rethought. In this context the concept of self-organization is nowadays widely discussed in management science. Contrary to a tayloristic approach where organizations were perceived as social units which could be controlled mechanically from the top, the concept of self-organization is based on the idea that social units are networks of autonomous self-regulating subunits whose behaviour cannot be controlled easily from the outside. To be able to exploit the benefits of self-organizing systems, organizational structures have to be renewed: the divison of labour among the subunits has to be changed, the hierarchies have to be flattened while self-coordination by non hierarchical communication among the subunits has to play a more important role. Within this process of reorganization, information systems are of importance. They offer options for alternative modes of division of labour and new patterns of coordination within an organization. On the other hand the design of these systems has to respond also to changing organizational requirements. That means that the relationship between the technical and the organizational changes is characterized by reciprocity and interdependence. Therefore, an integrated approach to organization and technology development is required. The given dynamics of the environment force organizations to react permanently. This requires an iterative approach to change. Once an intervention has been performed within this development process, its effects have to be reconsidered whether they led to the intended result. According to the paradigma of self-organization, it cannot be predicted from the outside in which way organizations as a whole and single subunits will react to changing environmental conditions. Thus, a process of integrated organization and technology development depends on the active participation of the single subunits affected.
