Abstract
Human motion has been analyzed in the field of welfare, care worker, sports and so on. Motion capture system is one of the useful measurement equipments of human motion [1]. It measures refection of light from some markers which are attached on a body and calculates their positions based on a coordinate set beforehand. In this paper, we are going to measure motion of a rider on a unicycle by motion capture system and describe it by mathematical model. As numerous multivariable time series data for a motion is obtained by this system, processing multivariable time series data is needed to model the motion.
