Due to the reduction of the number of persons engaging in traditional skills, efficiently archiving traditional skills is needed to preserve and transmit them to future generations. It is important for archiving various traditional skills to concisely and accurately represent several fundamental movements in the traditional skills. Additionally, a pause called “Ma” in Japanese is also a remarkable component in many kinds of traditional skills. We thus propose an efficient representation of the fundamental movements and pause focusing on the motion data obtained by a motion capture system and given as time series of the positions of some markers. The effectiveness of the proposed representation is evaluated through an experiment of discriminating several kinds of fundamental movements and the pause in Japanese traditional tea ceremony. We show that many kinds of fundamental movements can be concisely described and accurately discriminated by using the proposed representation. In addition, we give consideration about the proposed representation for an efficient archiving.
