虚拟现实手部康复训练系统的设计与实现

将虚拟现实技术应用到康复医学领域，可有效克服传统康复训练方法的局限性，实现安全、舒适和主动的康复训 练。本文设计并实现了一套虚拟现实手部康复训练系统，系统由交互设备、人机交互软件和虚拟环境三部分组成。交互 设备采用 5DT 公司生产的 5DT Data Glove 14 Ultra 数据手套，而人机交互软件运用 Visual Studio 2012 作为开发工具，基于 MFC 编写，实现了用户管理、数据采集、手势信号分类、实时手势识别测试等功能。构建的虚拟场景使用 Flash 游戏， 通过 MFC 和 Flash 游戏之间通讯使用者能使用手势信号实现游戏操控。本文的实验结果表明：虚拟现实手部康复训练系 统能够指导使用者进行有效的手部康复训练，Flash 康复训练游戏能有效提高使用者进行康复训练的积极性和主动性。

Design and Implementation of a Training System of Hand Rehabilitation Based on Virtual Reality

The use of virtual reality technology in limb rehabilitation training could overcome the limitations of traditional rehabilitation methods, realizing the safe, comfortable and active rehabilitation training. In this paper, a rehabilitation training system based on virtual reality was designed for the recovery of impaired hand functions and evaluated in healthy projects. The training system was developed by using an interactive device, a human-computer interaction software and the virtual environment. The 5DT Data Glove 14 Ultra was used as the interactive device. The human-computer interaction software implemented with Visual Studio 2012 consisted of user management module, data collection module, classification module and real-time gesture recognition module. For the virtual environment (VR), a flash game was developed and used, which could be controlled by hand gestures through the communication between the VR environment and users. The proposed training system could be beneficial in improving the outcome of the hand function rehabilitation. Moreover, the use of flash games could improve the enthusiasm and initiative of the users effectively in rehabilitation training.
