Modeling method based on wave equation for reproduction control of haptic sensation

Recently, real world haptics are researched. In this paper, the environment copying system is focused. The environment copying system is one of the real world haptics techniques. The environment copying system achieves saving and reproduction of real world environments haptic sensation. The environment copying system needs environment model. The environment model calculates environment reaction force. Thereby, haptic sensation reproduction is achieved. The conventional model consists of a pair of spring and damper. It can not reproduce oscillation of the environment. In this paper, the model based on wave equation is proposed. It can reproduce oscillation of the environment.
