项目摘要

In this project, we obtained some basic results on tactile feeling interfaces. The aim of the research was realizing a system to transmit tactile feeling from an artificial sensor to a human skin with high fidelity. Toward this goal, we studied new basic physical effects for haptic devices, sensors that can sense tactile feeling like human skin, new mechanisms of tactile display, and information processing in human skins. The results are summarized as follows.1) New principle of an ultrasound emitterA new principle of an ultrasonic emitter was studied. Intense ultrasound generates radiation pressure on the skin suitable for tactile display because it can be accurately controlled with high spatial resolution and temporal response. A thertnally-induced-ultrasound emitter studied here is suitable to generate such intense sound. We showed the basic principle of sound generation and methods to heighten the intensity, and we finally obtained intense ultrasound more than 1 kPa.2) Tactile disp … More lay and informational studies on human tactile sensationTactile resolution of the human skin was clarified. We proposed a hypothesis on determination of human tactile feeling. Since there were paradoxical properties in human tactile perception that a human skin has relatively large two-point-discrimination-threshold while it can distinguish very fine feature of the object surface, the tactile resolution for realistic tactile display had been a mystery. Our hypothesis explains this and was proved by experiments.3) Tactile sensorFor realizing an elastic sensor skin with faithful properties to a human skin suggested by above results, we proposed a wire-free tactile sensing chip based on optical connection. Each sensing chip with an individual 10 detects 6 components of stress tensor and sends the digital signal with emitted light from the chip. Since the sensing chips need no wire, they can be located three-dimensionally in a sensor skin with high density without loosing the skin's elasticity. The sensing chip including VLSI chip was designed. Less

在这个项目中，我们获得了一些有关触觉感觉接口的基本结果。这项研究的目的是实现一种系统将触觉感觉从人造传感器传递到具有高富度性的人皮肤的系统。为了实现这一目标，我们研究了触觉设备的新基本物理效果，传感器可以感觉到触觉感觉像人类皮肤，触觉显示的新机制以及人类皮肤中的信息处理。结果总结如下。1）在这里研究的新型横向引起的耗散发射器适合产生这种强烈的声音。我们展示了声音发电的基本原理和提高强度的方法，最终获得了超过1 kPa的强烈超声。2）触觉剥离……对人类皮肤的人类触觉触觉分辨率进行了更多的外行和信息性研究。我们提出了关于确定人类触觉感觉的假设。由于人类的触觉感知是人类皮肤具有相对较大的两点歧视阈值，而它可以区分物体表面的特征非常好，因此现实触觉显示的触觉分辨率是一个谜。我们的假设解释了这一点，并通过实验证明了这一点。3）触觉传感器实现具有上述结果所建议的人类皮肤具有忠实特性的弹性传感器皮肤，我们提出了基于光学连接的无电线触觉传感器芯片。每个具有单个10的传感器芯片可检测到6个应力张量的组件，并以芯片发射光发送数字信号。由于灵敏度芯片不需要电线，因此它们可以在高密度的传感器皮肤上三维位置，而不会松开皮肤的弹性。设计了包括VLSI芯片的传感器芯片。较少的
