IMPACT, Improving and Motivating Physical Activity using ContexT, is a system that monitors and informs users about their physical activity and the context in which the activities happen. The system shows real-time information on a phone interface and historical information on a desktop and online interface. By contextualizing physical activity, the system increases users' awareness of their physical activity.
