Embodiment Construction

[0026] In order to detail the technical content, structural features, achieved goals and effects of the present invention, the following will be described in detail in conjunction with the accompanying drawings.

[0027] Such as figure 1 As shown, the present invention combines Leap Motion hand motion capture, computer game module, data processing and transmission, and virtual reality technology, and proposes a new method for rehabilitation training for users with hand function impairments. It includes two parts: hand motion recognition based on Leap Motion and immersive virtual training scene based on VR helmet rendering. First, Leap Motion captures the three-dimensional position information of 21 joint points of the user's hand, and transmits it to the computer after processing by the internal microprocessor. The host performs data processing analysis and pattern recognition, and completes the synchronous real-time control of the virtual hand in the scene. Then use the Unit...

Abstract

The invention relates to a hand function rehabilitation training system based on Leap Motion and VR and an implementation method of the system. According to the hand function rehabilitation training system based on the Leap Motion and VR and the implementation method of the system, a sensing capture technology and a virtual reality technology are combined; Leap Motion hand movement tracking and high-precision finger recognition technology are adopted to acquire the motion data of the hand of a user, the motion data are mapped to an immersive virtual scene constructed by the VR so as to be applied to real-time interaction; and training tasks which are closed to daily life such as gesture training and finger control ability improvement training such as pinch by two fingers, grasp by a hand in a spherical shape, and grasp by a hand in a columnar shape can be set; and rehabilitation programs can be provided for users with hand dyskinesia caused by illness or injury. With the system of theinvention adopted, the interest and initiative of the user's in rehabilitation can be improved, the effect of the motor nerve function reconstruction of the user can be accelerated; and the current shortage of physician resources can be effectively alleviated.

Description

technical field [0001] The invention relates to the fields of rehabilitation engineering and virtual reality, in particular to a hand function rehabilitation training system based on the combination of Leap Motion and VR and an implementation method thereof. Background technique [0002] According to the report of the World Health Organization, the number of users who need rehabilitation treatment due to motor dysfunction caused by stroke is increasing year by year. Among them, hand dysfunction is one of the main symptoms caused by stroke. It is specifically manifested as difficulty in stretching the interphalangeal joints and metacarpophalangeal joints, loss of grasping, fingers and other fine joint control ability, which seriously affects the daily life and work ability of users. Family and society have brought a heavy burden. It has been proved by research that active rehabilitation training can help the recovery of the user's limb motor function and promote recovery. ...
