基于虚拟现实的力反馈设备的研究与应用

摘要

作为人机交互实现的关键,力反馈设备的性能直接决定了力觉交互的效果,它能够尽可能真实地再现虚拟环境中的质量、惯量和硬度等信息。详细介绍了基于虚拟现实的力反馈设备的发展历史和研究现状,手指型、手臂型和全身型,许多已广泛应用于虚拟手术、虚拟维修、遥操作等领域。对这些现有的力反馈设备类型作了分析比较,并介绍了其在不同领域的应用情况,最后展望了其发展趋势,针对力反馈设备未来的研究方向提出了建议。%As the key of human-computer interaction,force feedback devices whose performance determines the effect of force interaction can reproduce as truly as possible the weight,inertia and hardness as well as other information in the virtual environment.In this paper,we first present the history and the current situation of force feedback devices.The current force feedback devices mainly include finger-type,arm-type and body-type;many have been widely used in virtual surgery,virtual maintenance,remote operation and other fields.Then,we make a comparative analysis of the existing equipment types,and their applications.Finally,we point out the trends of this kind of equipment.Suggestions are given for the future study of force feedback devices.
