The invention discloses a multi-person interactive virtual reality rehabilitation training and evaluation system comprising a multi-source sensor module, a signal receiver, a computer-side and a virtual reality processing unit. Multiple patients carry out group rehabilitation training in rehabilitation training fields or in rehabilitation training groups by means of the Internet; aiming at rehabilitation training on patient body parts, the wearable multi-source sensor module based on acceleration, gyroscopes, magnetometers, force sensors, and bending sensors is developed for data collecting, signal processing and feature extracting for rehabilitation training; multiple daily life situation interactive games are developed and models and interfaces of rehabilitation training movement characteristics and daily life situation interactive games are established so that patients carry out multiple-person interactive feedback rehabilitation training and rehabilitation assessment is carried out on the rehabilitation training effects of patients. The system of the invention is good for increasing the activeness of patients in rehabilitation training, enhancing the rehabilitation training effects and increasing the daily life self caring ability of patients.
