Currently, stroke is the leading cause of adult disability in the US. Most of the stroke patients suffer from great difficulties and they need a better way to boost their rehabilitation process. Mirror therapy is the method medical professional perform to reconnect damaged brain circuits. In general, stroke rehabilitation process is best when patients are performing a great number of repetition. However, because of lack of physical abilities, the task of repetition soon seem boring and thus patients are not motivated to do what they are suggested. In this project, Holographic Eletromyographic Automated Rehabilitation Technology (HEART), we are trying to use Mixed Reality (MR) technology, with the help of medical professionals, to create a rehabilitation game for the patients. This project would be interesting for patients to perform more repetition for their health.
