Research of VR-BCI and Its Application in Hand Soft Rehabilitation System

For patients with hand dysfunction, a hand soft rehabilitation system based on Virtual Reality (VR) and Brain- Computer Interface (BCI) technology is designed and manufactured. Virtual reality uses 3ds Max and Unity3D for 3D modeling and animation. Three scenes of virtual reality and multiple functions of the system are used to improve the effect of patients’ rehabilitation training. The brain computer interface technology based on motor imagination is used to transform patients’ passive training into active control, and a neural pathway from brain to limbs is constructed in vitro. The research and development of this system can replace rehabilitation physicians to help patients with rehabilitation training. It can improve the enthusiasm, immersion, attention and concentration of rehabilitation training, and provide a more effective and scientific rehabilitation treatment for patients. Through the analysis of the corresponding experimental results, the feasibility and effectiveness of virtual reality technology and brain computer interface technology in the rehabilitation system are verified.
