力触觉人机交互技术是虚拟现实中人机交互的重要组成部分,它通过模拟人类对真实物体的力触觉感知过程,将虚拟环境的力触觉信息真实地反馈给人,极大地提高了虚拟环境的交互性和临场感程度.本文从虚拟对象和力触觉表达方式的差异出发,综述了力触觉建模技术和力触觉再现设备的研究现状,并分析了各种模态的力触觉交互技术的特性,提出了基于云端的力触觉人机交互信息感知系统框架、研究进展及应用,最后对多模态力触觉交互技术的发展趋势进行了展望.
The tactile human-computer interaction technology is an important part of the human-computer interaction in the virtual reality. It realistically reacts the force tactile information of the virtual environment to the human by simulating the human’s tactile perception of real objects, which greatly improves the virtual environment This paper summarizes the research status of force-tactile modeling and force-tactile reproduction devices, and analyzes the influences of various modes of force-tactile interaction technology This paper puts forward the framework of the tactile human-computer interaction sensing system based on the cloud, the research progress and the application. Finally, the development trend of the multi-modal force tactile interaction technology is prospected.
