基于Unity 3D的虚拟现实手部训练系统设计

Design of Virtual Reality Hand Training System Based on Unity 3D

脑卒中是一种致残率很高的疾病,其中,由脑卒中导致的手部的感觉与运动功能障碍是脑卒中常见的后遗症,手部功能的恢复对脑卒中患者的生活质量提高具有重要意义。人们日常生活与工作中大多都会涉及肢体间的协调运动,当受损肢体与未受损肢体协调运动时,这种肢体间的连接动作有利于患有单侧运动障碍的患者功能恢复。本研究首先设计一款能够测量双手活动角度的数据手套,使用无线蓝牙传输手部运动数据,同时结合基于Unity3D的虚拟现实技术,控制虚拟现实场景中的角色运动,实现建立患者手部康复训练的虚拟训练平台。

Stroke is a disease with high disability rate.The most important sequela caused by stroke is the sensory and motor dysfunction of hand.The recovery of hand function is of great significance to improve the quality of life of stroke patients.Most of people’s daily life and work involve coordinated movement between limbs.When an impaired limb moves in harmony with an unimpaired limb,this interlimb connection helps people with unilateral dyskinesia to recover function.Firstly,this paper designed a data glove that can measure the angle of hand movement,used wireless Bluetooth to transmit the data of hand movement,and combined the virtual reality technology based on Unity 3D to control the movement of characters in the virtual reality scene,so as to realize the establishment of a virtual training platform for patients’hand rehabilitation training.
