Abstract So far, in. pervious virtual reality systems, haptic presentation devices have been developed and their usages have been discussed However, combination effects of tactile and haptic sensations have not been investigated in spite of their possibilities on virtual reality systems. In this study, we developed a mouse capable of presenting pressure distribution and slippage force to discuss the combination effects on virtual reality. The mouse was equipped with bimorph piezoelectric actuators and electro-magnetic linear motors to present pressure and slippage force respectively. In order to evaluate the presentation accuracy of the mouse, we performed a series of edge tracing oriented to several directions. In the present experiments using real step-height specimen, the smallest standard deviation is obtained from horizontal edge while the largest constant error is obtained from horizontal edge. Although human subject judges horizontal edge direction with high discrimination accuracy, recognized orientation is deviated from horizontal datum line.
