A virtual rehabilitation system for hand dysfunction based on natural interaction of hands and objects

Abstract

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. A virtual rehabilitation system for hand dysfunction based on the natural interaction of hands and objects, including a processor module for establishing and displaying virtual rehabilitation training scenes and completing the preprocessing, analysis and recognition of skeleton data, image information and electromyographic signals, and hand rehabilitation Equipment box, signal acquisition device, hand-object interaction recognition module, virtual rehabilitation training scene display and feedback module, and evaluation module. The rehabilitation system of the present invention innovatively combines the patient's daily hand movements, rehabilitation equipment and virtual scenes, and realizes hand-object interaction recognition by performing multiple feature extraction and multi-rule learning on skeletons, images and electromyographic signals. Judging the completion of homework training tasks, and then achieving the purpose of precise rehabilitation of hand function.

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...

Problems solved by technology

The disadvantage of this type of method is that the wearing process is very cumbersome, and it may cause discomfort during training, and may cause secondary damage to the patient's hands

In addition, some systems use remote rod equipment and hand patches for rehabilitation training. The remote rod equipment has a single training item, while the hand patch has high requirements for the location of the patch, which is not suitable for patients to carry out rehabilitation training at home. Rehabilitation training for patients with facial dysfunction brings inconvenience
