Abstract:  Personal-Public Displays – a class of devices that presents actionable personal information not only to the user, but also to the public, including friends, family, colleagues, neighbors and even strangers. Six properties are outlined that we believe are important for such information displays to embody. These build on two well-established methods for inducing behavior change: presenting pertinent information at the point-of-decision and leveraging social influence. To investigate the effectiveness of our concept, we have chosen a popular, but challenging target: motivating physical activity. This led to the development of Pediluma, a shoe accessory that tracks and visualizes the wearer’s physical activity by varying the intensity of a lighted housing. Results from a two-week, seventeen-participant user study indicated people wearing our device significantly increased their physical activity.

Role: Conducted real-world user study of participants wearing a pedometer-like device that reflected the environmental impact of their physical activities.  Assisted in the design of the study, designed and fabricated wearable devices, conducted setup and all intro and exit interviews.
