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，我们得到了一些关于触觉界面的基本结果。这项研究的目的是实现一种系统，将触觉从人工传感器传输到人类皮肤上，并保持高保真。为了这个目标，我们研究了触觉设备的新的基本物理效应，可以感觉到像人类皮肤一样的触觉感觉的传感器，新的触觉显示机制，以及人类皮肤的信息处理。研究结果总结如下：1)超声发射器的新原理研究了一种新的超声发射器原理。强超声波在皮肤上产生适合于触觉显示的辐射压力，因为它可以通过高空间分辨率和时间响应进行精确控制。本文研究的热感应声发射器适用于产生如此强烈的声音。我们展示了声音产生的基本原理和提高强度的方法，最终得到了超过1kPa.…的强超声波更多关于人类触觉的平实和信息性研究阐明了人类皮肤的触觉分辨率。我们提出了一个关于人类触觉决定的假说。由于人类的触觉感知具有矛盾的性质，即人的皮肤具有相对较大的两点辨别阈值，而它可以区分物体表面的非常细微的特征，因此用于逼真触觉显示的触觉分辨率一直是一个谜。我们的假设解释了这一点，并得到了实验的验证。3)触觉传感器为了实现上述结果所建议的具有与人类皮肤相同属性的弹性传感器皮肤，我们提出了一种基于光学连接的无线触觉传感芯片。每个带有单独10的传感芯片检测6个应力张量分量，并发送带有从芯片发出的光的数字信号。由于传感芯片不需要电线，因此可以在不损失皮肤弹性的情况下，将它们三维放置在高密度的传感器皮肤中。设计了包括VLSI芯片在内的传感芯片。较少
