基于电致振动效应的大面积多模态触觉再现系统

Large Area and Multi-modal Tactile Rendering System Based Electrovibration Effect

因大面积、多模态(力触觉、视觉等)融合的触觉再现终端具有较高的沉浸感和交互真实感,已成为该领域研究热点。基于高压驱动源、ITO导电层、绝缘膜等产生的电致振动效应,结合光学手指位置检测模块以及LCD显示模块,实现了基于摩擦力控制的触觉再现和视觉再现融合的多模态人机系统。通过手指摩擦力等级区分实验和静态场景虚拟物体纹理感知实验,验证了该触觉再现系统的有效性和真实性。

The large area and multi-modal(texture,tactility,temperature)tactile rendering terminal becomes the focus of the study,because of the advantages of free space for operating and higher sense of reality.A tactile rendering system merging with the sight rendering is completed based on the friction control of the finger and tactile plate.Its effectiveness and reality are verified by the experiment on the identification of the friction level and the recognition of the texture of virtual object.
