As factors determining roughness sensation of dot pattern, both spacing and curvature of dot are assumed. In this study, the relationship between these two dimensional parameters and the roughness sensation was investigated. We used a 3D printer to produce various types of samples with different combinations of curvature and spacing, and conducted sensory evaluation to select combinations with the same sense of roughness from among them. As a result of the experiment, as the dot curvature is larger (smaller), the smaller (larger) dot spacing is selected, and a contour map of roughness sensation is created on these two dimensional planes. It was found that roughness sensation is proportional to logarithm of dot curvature, assuming that roughness sensation is proportional to logarithmic value of dot spacing. By this experiment, the magnitude of the influence of dot shape in roughness perception and its individual difference were found.
