Preservation and reproduction of real-world haptic information

Artificial acquisition and reproduction of human sensations are basic technologies of industrial applications. Recently, haptic sensation is attracted attention as the third multimedia information. Such sensation is kind of bilateral sensation since it is subject to the law of action and reaction in the real world. From the point of view, real-world haptics is the key technology for future haptic technology. Bilateral connection of haptic systems with force feedback ability realizes telecommunication between remote human operators. The paper shows a "real-world haptic system (RHS)" as a spatiotemporal coupler of real-world haptic information. Once human motion is stored using RHS, it is possible to reproduce it at anytime and anywhere. Furthermore, the stored motion components are integrated and reproduced in one motion. It will be useful for digital preservation of motions by skilled experts as the haptic database. The experimental results show the viability of the proposed method.
