Supporting Weight Loss Through Digitally-Augmented Social Expression.

In this paper, we present the design, prototyping and implementation of i-Ribbon—a wearable device designed to support weight loss through digitally-augmented social expression. Starting with an Obesity Awareness Ribbon, we introduced the exploration process and formation of the i-Ribbon concept. Prototypes of different fidelity were built during the design process, including a working system that could extract the user’s personal health-related data through a mobile application and sent it to a wearable expression device. Evaluation through interview has been conducted. Base on the reflection on design, prototyping and evaluation process, we summarize the insights and discuss the options for future work.
