Progress in multimedia technology started from the telecommunication of audio information using telephones. And the spread of the interne can telecommunicate visual information using visual telephones. In addition, in recent years, we realize the sense of touch using a device called as a haptic interface. This technology is expected to play an active role in a wide variety of fields for technology of producing sense of touch in addition to technology of producing sense of both sight and hearing which is used in many applications. However, compared to sense of both sight and hearing, sense of touch has not been assessed quantitatively. This paper clarifies a how to recognize objects in virtual reality using haptic interfaces controlled by impedance control system. Results show that objects' hardness and grasp approach direction are great factors when we recognize and memorize the objects.
