纹理力触觉建模与表达技术研究综述

摘要

力触觉再现作为一种新兴的信息传递方式,对提高人机交互的真实感和准确性具有重要意义.纹理的力触觉表达是借助触觉反馈通道反映人与环境交互过程中物体表面凹凸特性.介绍了纹理力触觉表达的研究背景,阐述了纹理力触觉表达系统的基本原理,归纳了纹理力触觉表达的触觉特征提取和建模方法,并对不同类别的建模方法的特点和问题进行了分析,最后给出了纹理力触觉表达技术的未来研究方向和建议.%Haptic rendering,as a new way of information transmission,is very important for improving the sense of reality and accuracy of human-computer interaction.Haptic texture displaying reflects the surface concave and convex characteristics by means of tactile feedback channel during human-computer interaction.The research background of haptic texture displaying is introduced and the basic principle of haptic texture displaying system is expounded.Then correlational research achievement both at home and abroad,different types of feature extraction and haptic texture modeling are analyzed.Finally,the main problems in the research of haptic texture displaying are summarized,and further research ideas and suggestions are discussed.
