本文介绍了一个实验平台，用于研究触觉探索过程中人体指垫皮肤的拉伸和压缩。数码相机记录了手指在具有简单几何特征的透明表面上滑动时所产生的图案序列。通过跟踪指尖上的解剖标志，以高时间和空间分辨率测量皮肤变形。采用在线指纹识别技术获取高对比度指纹图像，提取显著特征（孔隙、谷末和谷分岔）。本文介绍了在有凹凸或孔洞的表面和平面上进行的实验结果。这项工作的动机是需要为使用外侧皮肤拉伸的触觉显示提供有意义的“触觉电影”。
This paper describes an experimental platform for the study of stretch and compression of the human fingerpad skin during tactile exploration. A digital camera records the sequence of patterns created by a fingertip as it slides over a transparent surface with simple geometrical features. Skin deformation is measured with high temporal and spatial resolution by tracking anatomical landmarks on the fingertip. Techniques adapted from the field of online fingerprintig are used to acquire high contrast fingerprint images and extract salient features (pores, valley endings and valley bifurcations). The results of experiments performed with surfaces with a bump or hole and flat surfaces are presented. This work is motivated by the need to provide meaningful “tactile movies” for a tactile display that uses lateral skin stretch.
