Hand functional disorder virtual rehabilitation system based on hand-object natural interaction

Abstract

The invention relates to a hand functional disorder virtual rehabilitation system based on hand-object natural interaction, and belongs to the technical field of virtual reality services. The hand functional disorder virtual rehabilitation system based on hand-object natural interaction comprises a processor module, a hand rehabilitation instrument box, a signal acquisition device, a hand-object interaction motion recognition module, a virtual rehabilitation training scene display and feedback module, and an evaluation module, wherein the processor module is used for establishing and displaying a virtual rehabilitation training scene and completing preprocessing, analysis and recognition of skeleton data, image information and myoelectricity signals. According to the rehabilitation system,daily hand actions, rehabilitation instruments and virtual scenes of a patient are combined innovatively, multi-element feature extraction and multi-rule learning are carried out on the skeleton, theimage and the electromyogram signals, the hand-object interaction action recognition is realized, the completion condition of the operation training task is judged, and the purpose of accurate rehabilitation of the hand function is achieved.

Description

technical field [0001] The invention relates to a virtual rehabilitation system for hand dysfunction based on the natural interaction of hands and objects, and belongs to the technical field of virtual reality services. Background technique [0002] Hands are an important carrier for information communication and emotional communication in human daily life. Studies have shown that the function of the upper limbs accounts for 60% of the functions of the whole body, while the functions of the fingers account for 90% of the functions of the upper limbs. Hand dysfunction will cause patients to be unable to take care of themselves to a certain extent, which not only brings inconvenience to the patient himself, but also brings burden to the patient's family members. Studies have shown that for patients with finger dysfunction, rehabilitation training with appropriate position and appropriate intensity is a very effective and important medical method. By performing certain rehabil...
