I will present an overview of work by my research group exploring the development and evaluation of sensor-driven mobile health technologies for measuring and motivating health-related behavior. We are creating prototype technologies that use context-aware sensing to empower people with information by presenting it in timely, tailored ways via home and mobile computing devices. I will outline our general approach showing examples of technologies developed in pilot projects, with a special focus on an effort to develop a new open-source tool for measuring physical activity type, duration, intensity, and location on common mobile phones for population scale health studies. This activity measurement system, and others we are working on using common mobile phones, provide new ways to create what are known as persuasive technologies using positive reinforcement and tailored, just-in-time messaging.
