This paper proposes searching system of haptic information. As with text, auditory, and visual information, the search system of haptic information is realized. The searching system proposed in this paper consists of the environmentcopying system and the search algorithm. Firstly, environmental data memory in the environment-copying system stores force responses in order to reproduce the environmental haptic sensation. After that, search algorithm calculates similarity between force response of bilateral controller and force from the environmental data memory. Thus, the proposed system is capable of calculation of search results relevant to haptic environment. By the experiments, validity of the proposed method is verified. The searching system will be useful for industrial applications, medical and welfare human support.
