Individuals who work in sedentary occupations are at increased risk of a number of serious health consequences. This project involves both a tool and an experiment aimed at decreasing sedentary activity and promoting social connections among members of the MIT Media Lab. Our system will ask participants to sign up for short physical challenges (ping pong, foosball, walking) and pair them with a partner to perform the activity. Participants’ overall activity levels will be monitored with an activity tracker during the course of the study to assess the effectiveness of the system.
