触觉纹理感知的研究需要高精度、高分辨率的纹理表面。鉴于人类手指对表面细节的微小差异非常敏感，纹理表面需要精确到微米级。采用真实的和虚拟的高清晰度纹理表面，研究了正弦光栅的振幅鉴别特性。尽管接触模式不同（指尖在真实的纹理上，一点在虚拟纹理上），但获得了相似的阈值。研究结果支持使用高位置分辨率的力反馈设备在研究纹理感知，特别是在制造的真实的纹理是超出了制造过程的分辨率或只是太昂贵和耗时的情况下。
Research on haptic texture perception requires the availability of textured surfaces with high precision and fine resolution. Given the exquisite sensitivity of the human fingers to minute differences in surface details, the textured surfaces need to be precisely defined to a micron level. Real and virtual high-definition textured surfaces were used in the present study of amplitude discrimination of sinusoidal gratings. Similar thresholds were obtained despite the difference in contact modes (fingertip on real textures and a point on virtual textures). The results support the use of high position-resolution force-feedback devices in studying texture perception, especially in situations where the fabrication of real textures is either beyond the resolution of the fabrication process or simply too expensive and time-consuming.
