Does Exploratory Hand Movement Provide Information on Tactile Sensations?
Takumi Yokosaka · NTT technical review · 2020
People move their hands in a variety of ways, such as tracing a finger on a material to feel its roughness or pushing a materials' surface to feel its hardness, to judge the feel of materials around them.Many studies on human tactile sensation did not focus on such hand movements.This article introduces my studies on investigating whether hand movements-and even eye movements-can be used to provide information for estimating the tactile sensation felt by a person.These studies are expected to provide not only important information for clarifying the mechanism of tactile perception but also help in designing guidelines for tactile-information display devices attached to arms and hands.
