Recently, skill preservation of an expert has been a serious problem of the medical or production fields. If digital skill preservation as a bilateral database is attained, it may become an innovative solution of the problem. This paper proposes a motion acquisition and reproduction of human motion by the interaction mode control. The proposed interaction mode control can control only the interactions between the systems. The interactions are abstracted by using the quarry matrix. Since the quarry matrix can divide systems into decoupled modes, it is possible to design a controller in the modal space. The order of the quarry matrix corresponds to the number of human finger. Thus the skilled motion by a human is easily obtained and analyzed in the modal space by using the quarry matrix. The experimental results show viability of the proposed method.
