The tactile perception of a surface texture is mediated by factors such as material, topography, and vibrations induced by the sliding contact. In this paper, sensory characterizations are developed together with topographical and tribo-tactile characterizations to relate perceived features with objective measurements of tribological and dynamic signals. Two sets of surface samples are used in this study: the first set is made of a commercial floor covering tiles that aim at counter-typing natural wood flooring, with both a visual and a tactile texture mimicking wood. A second set is custom-made by replicating the first set using a plain purple polyurethane resin. The comparison between tribo-tactile signals and sensory analysis allowed the identification of objective indices for textures with slight topographical differences. Even though the topography of the replicated samples is the same as their corresponding commercial products, the fact that the material is different, induces differences in the contact and vibrational parameters. This in turn modifies the discrimination performances during the sensory experiment. Tactile characteristics collected during sensory procedures are found to be in agreement with objective indices such as friction coefficients and induced vibrations.
表面纹理的触觉感知是由材料、形貌以及滑动接触引起的振动等因素共同介导的。在本文中，我们综合了感官特性、形貌特性和摩擦-触觉特性的研究，旨在将感知特征与摩擦学和动态信号的客观测量联系起来。本研究使用了两组表面样品：第一组由商用地板覆盖瓷砖组成，旨在模仿天然木地板的视觉和触觉纹理。第二组是通过复制第一组使用普通紫色聚氨酯树脂制成的。摩擦-触觉信号和感官分析的比较允许识别具有轻微形貌差异的纹理的客观指标。尽管复制样品的形貌与相应的商业产品相同，但由于材料不同，会导致接触和振动参数的差异。这反过来又会改变感官实验中的判别性能。在感官过程中收集的触觉特征与摩擦系数和诱导振动等客观指标相符。
