Research on the Usability of Hand Motor Function Training based on VR System

Virtual reality technology can provide immersive experiences to facilitate limb motor training, including visual, auditory, and force touching, etc. In this paper, we develop a VR-based hand motor rehabilitation system. This system collects and analyzes users’ limb behavior data, customizes and trains hand motor training programs according to different scenarios and different levels of difficulties, and integrates management, evaluation, customization, and feedback functions. Then we conduct several experiments to verify the effectiveness and usability of the rehabilitation system. Through the FMA, NHPT, and SUS scale assessments on healthy individuals, the analysis concluded that the average SUS score of all participants was 80, verifying that the hand rehabilitation system is practical and feasible. Upper limb motor disorder patients’ trials and data analysis will be carried out in the future.
