This paper presents a design case study of workplace health promotion (WHP) in office settings, contributing to its understanding and continuous improvement. Our contextual study revealed that office settings are characterized by conflicts such as self-tracking versus monitoring, individual versus collective preferences, and prescribed versus personalized needs for health activities. We explored these conflicts through the design of a mobile application that uncovered design challenges, with several implications for WHP technologies. Co-design and formative evaluation showed increasing needs for personalization, supporting a continuous design-in-use imperative and a more context-rich view of workplace health technologies as multi-relational.[cite: 3]

This work-in-progress examines how rural health professionals and end-users perceive chatbots for health service navigation. Through interviews with six professionals and thirteen end-users, we identified four critical design tensions. The groups converged on: trust requires transparency, not technical sophistication; humans are irreplaceable in sensitive situations. However, they diverged on priorities: professionals emphasized institutional integration, end-users emphasized privacy and usability. Our findings challenge conventional assumptions. Confident wrong answers destroy trust more than honest uncertainty. Humanization attempts backfire. Escalation pathways must lead somewhere real. Chatbots need contextual data but collecting it creates privacy risk. Rather than technical solutions, effective design requires acknowledging competing stakeholder needs. We propose four principles: transparent source attribution, user-controlled interaction settings, real institutional integration, and governance transparency through local embedding. We reframe rural chatbots as infrastructure, not standalone technology. They must integrate into existing institutions and trust networks to reduce burden while preserving human-centered care.[cite: 3]

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.[cite: 3]

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. In this workshop we will discuss experiences with participatory methods in the health sector and explore how established methods can be made more inclusive so that they can be adapted to a wide range of stakeholders.[cite: 3]
[5] Bhattacharjee, Sourav (2023)[cite: 3]Promoting Health and Fitness among Office Workers: A Design-Case-Study [cite: 3]Abstract Links
This thesis work report presents a Design-Case Study methodology applied to the development and evaluation of a workplace health promotion solution within the unique context of employees in a public organization. The study explores the intricate dynamics between technology, health, and the modern workplace from a Human-Computer Interaction (HCI) perspective. Thematic analysis of interviews with eight participants reveals three central themes: the impact of workplace challenges on personal life, the role of motivation through awareness, and the necessity of understanding diverse user requirements. Design implications derived from these themes provide actionable guidance, emphasizing the importance of tailored interventions that acknowledge workplace needs, integrate nudging functionalities, ensure privacy-aware design, prioritize motivation, and leverage team-based approaches. User feedback during the evaluation phase uncovers usability challenges and user perceptions, highlighting the iterative nature of design. The thesis will contribute to HCI by highlighting the human-centered aspects of workplace health promotion and providing practical insights for organizations seeking to enhance employee well-being. The findings emphasize the importance of ongoing user engagement, responsiveness, and a commitment to user-centered design in the pursuit of holistic workplace well-being.[cite: 3]
