Abstract: Aiming at the deficiency of the current interactive system for balance training, this paper formulates a set of balance training strategies and human-computer interaction strategies, and develops an interactive system for balance training based on plantar force and posture information. Three kinds of virtual training games are designed based on the information of plantar force and human leg posture. The virtual games implement real-time graphical display of sensor data with functions including background music, voice guidance, and voice-based error correction. Through the experimental test of prototype, it is proved that the interactive system can improve the static and dynamic balance ability, and the training is accompanied by a variety of visual and auditory feedback, which ensures the interest and immersion of human-computer interaction, and can provide positive gains for the patients' balance training.
