AI Technical Summary

Technical Problem

Users often struggle to ensure the accuracy of their movements during musculoskeletal rehabilitation training, lack sustained motivation, and receive timely and accurate feedback on the effectiveness of their training.

Method used

By establishing a three-dimensional coordinate system through a VR headset, monitoring the movement trajectory of the controllers, and setting a fraction ball in the VR headset to guide users in musculoskeletal exercise training, the effect of the user touching the fraction ball can be judged by monitoring the position of the controllers, thereby realizing the healthy guidance and effect verification of the user's musculoskeletal exercise.

Benefits of technology

It improves the accuracy of joint movement training and users' sustained training motivation, and enables timely feedback and self-evaluation of the training effect.

Abstract

The application relates to the field of virtual reality technology, in particular to a bone joint movement rehabilitation training method and device based on virtual reality technology. A three-dimensional coordinate system is established through binocular vision cameras of a VR helmet, two circular arc movement trajectories of a calibration action are found, a corresponding shoulder position in a circle center coordinate and a radius corresponding to an arm length are found, the position of the circle center coordinate is adjusted according to the requirements of a preset action, the adjusted circle center coordinate is taken as the center to establish a first spherical coordinate range, the spherical surface coordinates of the first spherical coordinate range are taken as the center to establish a second spherical coordinate range, the second spherical coordinate range is displayed in the form of a fractional sphere in the VR helmet, the position of a handle in the three-dimensional coordinate system is monitored, and when the handle touches the fractional sphere, corresponding visual effects are realized in the VR helmet. The fractional sphere is established through cooperation of the VR helmet and the handle to guide a user to perform a preset rehabilitation training action, and the completion degree of the training action is verified and monitored through monitoring of the position of the handle.
