Abstract
Previously, "tele-touch" was proposed. In this concept, tactile sensation during rubbing physical surface can be reproduced in remote site. To indicate tactile sensation in the remote site, previously developed surface acoustic wave tactile display can be utilized. A dummy finger to acquire the tactile sensation of the physical surface was also proposed. Reproduced sensation did not coincide with the tactile sensation of physical surface by tele-touch system. To solve this problem, transfer function difference between real finger and dummy finger is considered. Improved tele-touch system is proposed. According to the proposition, identification of transfer function rubbing physical surface is needed. Many sample surface with periodic structure were applied to identify them. Identification of transfer functions was applied to tele-touch.
