Personal health-tracking technology which is to record and improve health is becoming popular. The personal health-tracking tools collect user’s living data and analyze it, planning for user to change his unhealthy behavior. However, there is was a lack of motivation in the current personal health-tracking system because it mainly focused on individuals. The importance of others in health behaviors and in personal health-tracking was well-established but designer still focused on the individual. How to design a part which allows other users to take part in personal health-tracking technologies system is a new challenge. Our research aims to help people to reach the right audiences and guidance when they share health information to get the motivation to change their behavior to maintain health. We designed a system to help people to finish the process: record data, find friends and coach, change behavior, help others. We use Augmented Reality technology to make the communication and interaction smooth. Also, an Augmented Reality game part is designed in our system to offer people more motivation to change their behavior. Preliminary experiment was carried out to verify the system is effective in terms of providing people with motivation.
