Outline of Final Research Achievements

I investigated the roughness that was one element which constituted feel of a material. A scaling of roughness sensation was performed for a physical index in the 3D surface texture parameter based on the ISO standard. I examined it for the purpose of establishing a design guidance of the feel of a material experimentally. 36 kinds of wrinkled textured surfaces was prepared. It is 12 kinds of patterns varying in the depth of each pattern to three phases. As a result of experiment, (1) it was cleared that the 3D surface texture parameter highest correlation with roughness sensation, (2) it was confirmed that the characteristic of the irregularity shape to judge a feeling of roughness to vary in an irregularity shape changed. (3) it was suggested that there was the sensory organ which significantly worked to judge a feeling of roughness.
