在指尖处应用切向皮肤位移已被证明在沟通方向上是有效的，并且具有几种应用的潜力。我们已经开发出一种便携式，指尖安装触觉显示器能够取代和拉伸的指垫的皮肤，使用7毫米的半球形触觉。进行指垫皮肤硬度的体内测试以确定有效地呈现刺激所需的力。其他设计参数，如刺激速度和位移，来自我们以前的工作。触觉显示器能够在平面内以任意取向呈现+/-1mm的位移，并且速率约为5 mm/s。使用外部测量来表征装置传动系统中的顺应性和反冲，并在软件中进行补偿以减少对装置滞后的影响。
Application of tangential skin displacement at the fingertip has been shown to be effective in communicating direction and has potential for several applications. We have developed a portable, fingertip-mounted tactile display capable of displacing and stretching the skin of the fingerpad, using a 7 mm hemispherical tactor. In vivo tests of fingerpad skin stiffness were performed to determine the forces required to effectively render stimuli. Other design parameters such as stimulus speed and displacement were derived from our earlier work. The tactile display is capable of rendering +/- 1 mm of displacement at arbitrary orientations within a plane and with rates of approximately 5 mm/s. Compliance and backlash in the device's drive train were characterized using external measurements, and were compensated for in software to reduce the impact on device hysteresis.
