A large percentage of the US population is overweight or obese, and a leading cause of this is lack of physical activity. Early fieldwork has shown that users have difficulty finding opportunities for physical activity and understanding how much exercise they get. To address these issues, we are exploring the use of mobile phone and web technology to monitor and inform users about their physical activity and the context in which the activities occur.
