Finger pad friction varies significantly between individuals due to personal differences and environmental effects. For this reason, comparison of the absolute friction values becomes non-informative and is rarely reported in literature. This work investigates whether friction data can be normalised to correlate between individuals. A set of textured samples were tested by 10 volunteers in dry sliding conditions with a range of normal loads up to 4 N. A reference smooth sample was used for each participant to normalise the dataset. The proposed approach allows to eliminate one of the unknown parameters, e.g., finger pad ridge contact area function, and discuss the data with respect to other variables.

由于个人差异和环境影响，各个人之间的指垫摩擦差异很大。因此，绝对摩擦值的比较变得无用，并且在文献中很少报道。这项工作调查了摩擦数据是否可以归一化以在个人之间建立关联。一组纹理样本由10位志愿者在干燥滑动条件下进行测试，其正常载荷范围为4N。每个参与者都使用参考平滑样本对数据集进行归一化。所提出的方法允许消除未知参数之一，例如指尖脊接触面积函数，并讨论关于其他变量的数据。
