MOTION ANALYSIS OF IAIDO SKILL BY USING MOTION DATA

Abstract

The purpose of this research was to make a quantitative analysis of lado (the Japanese art of using the Japanese sword). We carried out experiments of motion capture on Kirioroshi (a straight overhead slash) movement of Roppon-me (a sword thrust using two hands) in laido. The proficiency of lado performance was evaluated by calculating PCA (Principal Components Analysis) and cluster analysis of parameters of body movement. In addition, it is expected that our research will help laido practitioners and masters with lado training through provision of new information on lado movements.
