Abstract
Abstract There have been many studies as for the cutaneous sensation-based slippage length perceptual characteristics with respect to slipping planes on finger pad. As a result, it was clarified that we almost cannot sense the slippage speeds quantitatively, and, consequently, we almost cannot perceived the slippage lengths quantitatively. Thus, aiming to improve the cutaneous sensation-based slippage length perceptual accuracy, the authors introduced raised dots a series of raised dots: are embossed linearly along the slippage direction. Conducting psychophysical experiments, they modeled a perceptual characteristic with raised dots by using a power low. In addition, they confirmed that the performance of the raised dot-based framework was in no way inferior to that of the haptic-based framework in the haptic-based framework, the kinesthetic sensation works very effectively, and the performance is much better than that in the ordinary cutaneous sensation-based framework.
