摘　　要：触觉再现能够表达虚拟物体的表面特征,提高虚拟现实系统的真实感,因而成为人机交互领域内的研究重点。本文将空气压膜效应与电磁激励相结合,提出一种新颖的摩擦力控制触觉再现方法,并研制一种宽幅度摩擦力控制触觉再现系统,其中电磁激励用于增加摩擦力控制范围。经过一系列触觉感知实验验证了本系统的有效性,实验结果表明本文提出的方法相对于传统的摩擦力控制方法可以实现更宽泛的摩擦力系数控制。Tactile rendering is able to express the surface characteristics of virtual objects, enhances the fidelity of virtual reality systems, so it becomes the research focus in the field of human computer interaction. This paper presents a novel tactile rendering method through combining squeeze film effect with electromagnetic actuation, and a tactile rendering system based on wide friction control is presented, where the electromagnetic actuation is used to enlarge the controllable friction range. Several experiments have been carried out based on the prototype tactile rendering system, which verifies the proposed method. And the experiment results show that the proposed method is able to achieve wider controllable friction coefficients than traditional friction control based tactile rendering.
