Abstract

In this paper, we provide a perspective of touch technology. Two illustrative examples are shown here to explain the potential of touch technology. One is TouchLens, a new type of haptic devices different from tactile sensors and displays. Through this haptic device by our hand we can perceive geometric information of tiny bumps and holes that are difficult to be detected by our bare hand. TouchLens is not only useful for inspections in manufacturing but also attractive as a fun haptic tool by which everyone can understand the power of haptic technology easily. The other relates to a haptic illusion called the velvet hand illusion in which we can feel an illusory surface with strange velvety, slippery or oily texture when we lightly rub a wire mesh of hexagonal pattern between our hands, keeping our hands pressed gently together. We found that moving line stimuli were also effective for eliciting the velvet hand illusion. The observed illusory phenomena caused by a variety of moving line stimuli allow us to see the underlying mechanism of human tactile information processing. Because the obtained illusory sensation is very impressive, it is expected that the illusion can be utilized as a main effect of a new type of haptic display.

触摸技术的潜力

在本文中，我们提供了触摸技术的前景。这里展示了两个说明性的例子来解释触摸技术的潜力。一种是TouchLens，这是一种不同于触觉传感器和触觉显示器的新型触觉设备。通过这个触觉装置，我们可以用手感知到肉眼难以察觉的微小凸起和孔洞的几何信息。TouchLens不仅对制造过程中的检查有用，而且作为一种有趣的触觉工具也很有吸引力，通过它，每个人都可以轻松地了解触觉技术的力量。另一种是一种叫做“天鹅绒手错觉”的触觉错觉，当我们双手轻轻摩擦六边形图案的金属丝网时，我们可以感觉到一个具有奇怪的天鹅绒、光滑或油性质地的虚幻表面，双手轻轻地压在一起。我们发现动线刺激对丝绒手错觉也有效。通过观察各种运动线刺激引起的错觉现象，我们可以看到人类触觉信息加工的潜在机制。由于获得的错觉感觉非常令人印象深刻，人们期望这种错觉可以作为一种新型触觉显示的主要效果。
