Abstract: 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.

Key words: squeeze film effect, electromagnetic actuation, tactile rendering, friction control, virtual reality
