A basic study for haptic display on spatial perception by contact motion

Abstract

To carry out contact work naturally in virtual space, it is important to present somatosensory information by haptic display. Some haptic display systems have been already proposed and existed, but these systems are designed not considering the characteristics of human sense perception. So, in this study, we quantified the JND( just noticeable difference) of human spatial perception attended with touch sense and gave the necessary and sufficient accuracy for designing haptic display systems. First of all, we focused on a simple haptic task and carried out psychophysical experiments to quantify the JND.
