Raised-dot slippage perception on fingerpad using active wheel device

摘要

To improve the slippage perceptual characteristics with the fingertip cutaneous sensation, we have introduced raised dots on the surface of a wheel rotating on an index fingerpad. Examining the perceptual characteristics of the raised-dot slippages by psychophysical experiments, we obtained factor effects on the perception. As a result of ANOVA, it was confirmed there was a significant difference among the three surfaces: the 3.2 mm period of raised dots, the 12.8 mm periods of raised dots, and the without-raised-dots smooth surface.
