提出了一种新的静电触觉显示器，以实现紧凑的触觉显示设备，可以与虚拟现实系统。本研究的触觉显示器由一个薄的导电薄膜滑块与定子电极，激发静电力。该设备的用户通过用手指移动滑块来体验触觉纹理感觉。显示器通过向电极施加两相循环电压模式来操作。该显示器被集成到触觉遥现系统中，以实现具有实时触觉反馈的远程表面纹理的探索。在该系统中，PVDF触觉传感器和DSP控制器自动生成电压模式，通过触觉显示器呈现表面纹理感觉。与触觉显示器上的手指运动同步的传感器扫描纹理样本并输出关于样本表面的信息。该信息由DSP处理并真实的反馈到触觉显示器。触觉telepresentation系统进行了评估，在纹理辨别测试，并证明了79%的正确答案率。还报道了透明静电触觉显示器，其中触觉显示器与LCD组合以实现视觉-触觉集成显示系统。
A new electrostatic tactile display is proposed to realize compact tactile display devices that can be incorporated with virtual reality systems. The tactile display of this study consists of a thin conductive film slider with stator electrodes that excite electrostatic forces. Users of the device experience tactile texture sensations by moving the slider with their fingers. The display operates by applying two-phase cyclic voltage patterns to the electrodes. The display is incorporated into a tactile telepresentation system to realize explorations of remote surface textures with real-time tactile feedback. In the system, a PVDF tactile sensor and a DSP controller automatically generate voltage patterns to present surface texture sensations through the tactile display. A sensor, in synchronization with finger motion on the tactile display, scans a texture sample and outputs information about the sample surface. The information is processed by a DSP and fed back to the tactile display in real time. The tactile telepresentation system was evaluated in texture discrimination tests and demonstrated a 79 percent correct answer ratio. A transparent electrostatic tactile display is also reported in which the tactile display is combined with an LCD to realize a visual-tactile integrated display system.
