Human-Computer Interaction

To help promote behavior change, we leverage the power of social obligation, and conduct an experiment in which participants are paired together and asked to design a Behavioral Intervention Technology (BIT) customized to suit their partner’s behavior change goal.

The Challenge is a tool aimed at promoting social connections and decreasing sedentary activity in a workplace environment. Participants are paired with a partner to complete short physical challenges, leveraging social obligation and social consensus to drive behavior change.

SmileTracker is an app that uses facial expression recognition to take a screenshot of the user’s screen whenever they smile. The screenshot and image of the user’s face are saved, to help them remember positive content they encountered during the day. Users can opt to share their images to a public gallery.
