This workshop was a follow-up of the three co-design workshops that we had during the summer and fall of 2023 and aimed to further explore the interdisciplinary research field at the intersection of gamification, digital health, and human-computer interaction. In this workshop, participants were tasked with a series of fun activities, including providing feedback on the current prototypes developed by the research team, exploring new interaction forms of smartwatch applications, brainstorming new features for the gamified smartwatch apps, and even exploring the game player traits of the participants themselves. It was a ton of fun and full of positive vibes. We are grateful to all participants, student assistants, and Prof. Melcer for co-creating this amazing experience, and look forward to having everyone again in our future workshops. This project is supported by the KUAS Overseas Collaboration Grant 2023.
