Feature Quantification of Material Texture Perception Using a Force-Displacement Relationship *

The force-induced displacement distribution function (FDDF) is a physical quantity with a high degree of familiarity with product production parameters and sensibility values. In this study, we proposed FDDF (Stroke) as the texture perception by stroking FDDF implementation. Moreover, we showed that FDDF (Stroke) has a highly expressive tactile perception capability for hard materials.
