本文介绍了一种通过主动触摸增强表面起伏检测的装置。我们称之为“触觉接触透镜”的这种装置由薄片和布置在薄片一侧上的许多针组成。实验结果表明，通过该装置可以更准确地检测表面上的一个小凸起比裸露的手指，比通过一个平板。对这一现象的数学分析提出了两种可能的解释。其中之一在于引脚的类似于锯齿的行为。针将物体表面的局部倾斜转换为皮肤表面的切向位移。第二种是由离散接触引起的空间混叠效应。由于这种效应，皮肤表面位移的时间变化被有效地转换成皮肤组织应变的时间变化。这种分析的结果，然后讨论与其他敏感性增强材料，触觉传感机制，和触觉/触觉显示设备。
This paper introduces a device for enhancing detection of surface undulation through active touch. This device, which we call a “tactile contact lens,” is composed of a sheet and numerous pins arranged on one side of the sheet. Experimental results show that a small bump on a surface can be detected more accurately through this device than by bare finger and than through a flat sheet. A mathematical analysis of this phenomenon suggests two possible explanations for this phenomenon. One lies in the lever-like behavior of the pins. The pins convert the local inclination of the object surface into the tangential displacement of the skin surface. The second is the spatial aliasing effect resulting from the discrete contact. Due to this effect, the temporal change in the skin surface displacement is efficiently transduced into the temporal change in the skin tissue strain. The results of this analysis are then discussed in relation to other sensitivity-enhancing materials, tactile sensing mechanisms, and tactile/haptic display devices.
