In virtual reality (VR) study, there are two ways active and passive touches to explore a virtual object with the tactile mouse. There is an issue "which is superior active or passive touch?" The active touch is to touch and perceive an object actively, while the passive touch is to touch and perceive a change of an object passively. The purpose of this study is to evaluate a perception precision in active and passive touches to clarify the best exploration method. This experiment is exploring the degree of leaning of the edge line using the tactile mouse in the virtual space. We develop a new tactile display called a palm tactile mouse and evaluate the perception precision using an angle difference-threshold and a judgment probability-function calculated by constant method of the psychophysical experiment. As a result, we confirmed that perception precision is the best when explore speed is 90 mm/s, and the active touch is not different from the passive touch.
