近年来，人类触觉的再现在虚拟现实、机器人远程控制、计算机接口等领域受到广泛关注。此前，提出了一种利用表面声波（SAW）提供人体触觉的新方法。脉冲调制驱动电压激发定子换能器上静止SAW的时间分布。这种分布在SAW衬底表面产生波动摩擦。当指尖通过滑块探索具有爆发SAW的表面时，这种波动可以转化为振动，并在我们手指皮肤的机械感受器上被感知为触觉。根据该原理制作了SAW触觉显示器样机。通过滑块摩擦基材，我们可以感受到根据摩擦运动的控制下的触觉。开发了原型机的控制器。为了评价滑块钢球的振动，测量了控制下的钢球速度。选择两组控制参数，使操作者能够区分两种粗糙度感觉。通过大量受试者的实验，评估了选择的有效性。
Reproduction of human haptic sensation has lately attracted attention for various fields, such as virtual reality, remote control of robots, computer interfaces and so on. Previously, a novel method to provide human tactile sensation using surface acoustic wave (SAW) was proposed. A pulse modulated driving voltage excites temporal distribution of standing SAW on a stator transducer. The distribution generated fluctuating friction on the surface of SAW substrate. When the surface with burst SAW is explored by fingertip through a slider, the uctuation can be transformed into vibration and perceived as tactile sensation at mechanoreceptors in our finger skin. A prototype of the SAW tactile display is fabricated according to the principle. Rubbing the substrate through the slider, we can feel tactile sensations under a control depending on the rubbing motion. A controller for the prototype is developed. For evaluation of slider steel ball vibration, steel ball velocity under the control is measured. Two sets of the control parameters are selected so that operators can discriminate two kinds of roughness sensation. Effectiveness of the selection is evaluated through an experiment with a large number of subjects.
