| Abstract(in English) | It is important for trainees to grasp their own tendency and features of motion objectively and quantitatively with no labor and effort when they practice striking and thrusting motions of swordplay such as Tankendo (close quarter combat with short bamboo sword). To fulfil the above requirement, it is desirable that the trainees are supported by a system for capturing and analyzing, which allows them to immediately use on the spot without changing clothes with almost no labor and effort, whenever necessary. Our study therefore suggests a system capable of capturing and analyzing the postures of articulated human motions in a sagittal plane using at most 4-color spherical light reflective markers through one camera. Our system consists of 4 primary-color spherical light reflective markers, elastic belts with markers, indications for marker wearing positions and one small-size high-speed camera (cell phone). The styrene foam marker is formed into a small-sized light sphere on a thin plastic seat. Some of the markers are attached directly to a user’s body by means of double-coated adhesive tape. Others, which have been previously fixed to the elastic belts, are attached to the body by wrapping around the trunk, head and extremities. The indications for marker wearing positions instruct the user what color of marker should be attached to what site of the body according to the colors and size of user’s clothes and the color combination of objects in the background, following a given flow chart. |
