An AR system to motivate the trainer during the robot-assisted rehabilitation

People who suffer from motor disabilities resulting from stroke have trouble with their daily life and mental state. The recovery of limb function is an essential demand to improve the self-care ability of the patients. Physical rehabilitation is the mostly used treatment. Rehabilitation robots have freed the therapy from high-intensity repetitive work, however, in the absence of therapies, it's hard for patients to take the initiative to participate in exercise. The effect of rehabilitation training is greatly reduced. In this paper, we present a system which is aimed to use a virtual therapist in AR environment. In this AR system, the trainer can see the therapist assisting him in the exercise of rehabilitation and interacting with the trainer, as if there were a real therapist around. Through this new technique, the fear and boredom of the trainer are alleviated. More importantly, enhance the role of the patient's subjective initiative, in order to obtain a better training effect.
