Virtual reality (VR) mirror image therapeutic instrument

Abstract

The invention discloses a VR mirror image therapeutic instrument and belongs to the technical field of VR. The VR mirror image therapeutic instrument comprises a host computer, and a hybrid motion capturing system, a mirror image display, a doctor display and an input device connected with host computer. The hybrid motion capturing system comprises an inertial motion capturing module and an optical motion capturing module, the inertial motion capturing module cooperates with arms of a patient to capture motion of upper limbs, and the optical motion capturing module cooperates with palms of thepatient to capture motion of hands. The demonstrated therapeutic instrument has a more vivid mirror image effect, can improve a visual feedback effect greatly, quantity a treatment effect, and help adoctor to master the rehabilitation condition of the patient, and a treatment scheme can be made to make the treatment process standard.

Description

technical field [0001] The invention belongs to the technical field of virtual reality, and specifically relates to a virtual reality image therapy instrument. Background technique [0002] Mirror therapy refers to the use of the principle of plane mirror imaging to copy the picture of the healthy side to the affected side, allowing the patient to imagine the movement of the affected side, through optical illusions, visual feedback, combined with rehabilitation training programs. Since it was proposed, mirror therapy has been carried out based on plane mirrors or combined lenses. Due to the limitation of the device, it is difficult to quantify the standardization and uniformity of training, which affects the effect of clinical application. In the early treatment equipment, the mirror device usually uses a combination of mirrors or a camera device to copy the image of the healthy limb, and transplants it to the affected side to produce optical illusions and visual feedback. ...

AI Technical Summary

Problems solved by technology

[0004] 1. From the perspective of mirror image representation, mirror image generation is mostly a mirror or video image, with poor visual effects. Although a 3D model appears, it uses a standard model, which is not very applicable;

[0005] 2. For body motion capture, the optical motion capture and data gloves used in the application have a small collection range, which cannot achieve the overall motion capture of the body, and the accuracy of the capture needs to be further improved;

[0006] 3. Observation and manual recording are often used in treatment, and automatic data recording and analysis are not involved in most studies, and the standardization is not strong
