先前关于槽形铝瓦粗糙度的实验数据为粗糙度感知理论的测试提供了数据基础。建立了皮肤接触刺激瓷砖时的静态变形模型，并分别将11个变形参数与实验数据进行了比较。首先用近似方法测试所有参数，然后用更精确的方法重新计算较好的参数。三个参数，手指穿透凹槽的深度，手指在凹槽内的横截面积，以及皮肤与其静止位置偏差的横截面积，都可以很好地预测粗糙度，并将其作为手指力和凹槽宽度的函数。三种方法中的最后一种最能预测粗糙度作为陆地宽度的函数，并暂时首选作为“粗糙度的刺激因素”。从静态模型的所有预测表明，皮肤和瓷砖之间的摩擦系数的变化应该很少或没有影响。这个违反直觉的预测被一项实验证实了。
Previous experimental data on the roughness of grooved aluminum tiles provide a data base against which to test theories of roughness perception. A model based on the static deformation of the skin touching the stimulus tile is developed, and 11 parameters of the deformation are individually compared with the experimental data. All parameters were tested first in an approximate way, and then the better parameters were recalculated in a more exact manner. Three parameters, the depth to which the finger penetrates the groove, the cross-sectional area of the finger within the groove, and the cross-sectional area of the deviation of the skin from its resting position, all predict the roughness well as a function of finger force and groove width. The last of the three predicts roughness best as a function of land width, and is tentatively preferred as “the stimulus for roughness.” All predictions from the static model indicate that variation of the coefficient of friction between skin and tile should have little or no effect. This counterintuitive prediction was confirmed by an experiment.
