(Nagoya Institute of Technology) The mechanism of tactile sensation has not yet been solved though it is the basic sense of humans. NITech scientists investigated its mechanism and found the important cues in touch could be different for each person. When humans evaluate the roughness, different individuals weigh skin vibration information, spatial information, and other mechanical properties differently. The goal is to establish an estimation model of perceptual roughness ratings involving individual differences in the cognitive weights.
