Instead of building on a reactive health-care system centered around treating disease rather than preventing it, the Lab's Social Health Living Laboratory is focused on developing a proactive, social health system: a network of organizations and tools to give people the knowledge and support they need to maintain health, vitality, and happiness throughout their entire lives. This involves developing devices such as mobile phones that record our daily patterns, and smart exercise equipment that knows our personal patterns and life-style goals. This initiative integrates persuasive technologies, to help us make better decisions and adopt better behaviors; personal sensing, to increase our awareness of our bodies; personal collective intelligence, to collect knowledge from our peers; and socially aware computation and communication systems that are aware of us as social beings.
