Tactile texture measurement system based on the contact area deformation by using a transparent fake finger

Abstract

Humans perceive the surface characteristics of an object through the tactile perception at the fingertip. Our previous study measured the contact area deformation by a camera when forced displacement is given; however, the measurable object was limited to transparent ones. This research develops a new system that can evaluate the deformation of the contact area of a non-transparent object. We replaced a human's fingertip with a transparent fake fingertip and measured the deformation of the contact area when displacement is given. We compared the results of human's fingertip and the results of fake fingertip.
