Eliciting values through wearable expression in weight loss

This paper presents the work-in-progress prototype of i-Ribbon---a wearable device designed to elicit values in the context of weight loss. Starting with an Obesity Awareness Ribbon, we introduced the i-Ribbon concept. For prototyping, we built a system that could extract user's personal health-related data through a mobile application and sent it to a wearable device. The functional prototype enabled us to implement different interaction strategies to elicit corresponding values. Base on the reflection on design and prototyping process, possibilities of future research were identified.
