基于虚拟现实的力反馈交互系统应用技术

力反馈交互系统能够实现力觉信息反馈，弥补传统人机交互中反馈信息单一的不足，在虚拟现实系统中有着广 泛的应用。力反馈设备是人机力觉信息交互界面，是交互系统的重要组成部分。文章讨论了力反馈交互系统的应用组 成及数据信息传递流程，并以Omega．7设备为例，介绍了力反馈设备的机构及电气组成；介绍了虚拟环境的一般构建内 容和方法。最后对力反馈虚拟交互应用的进一步研究提出建议。

Application Technology of Force Feedback Interaction System Based on Virtual Reality

Force feedback interaction system can realize the feedback force information and compensate the shortage of less feedback information in the traditional human-computer interaction. It has extensive application in the system of virtual reality. Force feedback device is the interface of force feedback between human and computer interaction. and it's a very important part of interaction system. The composition and data transfer flow of force feedback interaction system was discussed. The mechanism and electrical composition of force feedback device were introduced. With Omega.7 device for example, the structure and composition of force feedback device was introduced. The general construction contents and methods of virtual environment were introduced. and some suggestions were proposed about the further study on application of force feedback virtual interaction.
