International audienceSome patients may have to stay at home, however they may need also some rehabilitation exercises. Sometimes this is not possible due to several constraints: distance, cost, availability, etc. Traditionally, rehabilitation sessions are performed individually or in groups in the same place. Studies have shown that group sessions can lead to better motivation and results. In this paper, we propose a system that allows rehabilitation sessions, within a distributed group of people, under the computer-assisted supervision of a coach. The system makes use of wearable technologies, web applications and pervasive computing. Group awareness and self-awareness are enhanced for better motivation and results
