Interpolation and extrapolation of quasi-periodic movement measured with magnetic motion capture system

摘要

For the purpose of investigating the relationship between human motions and subjective impressions, a new computer-graphics animation tool was designed. In the system, Several kinds of motion data were measured with the magnetic motion capture system and the pair of data gloves, and transformed into the time-series data of each joint angles to obtain the frequency information and phase information by FFT, with which new motions were synthesized by the inverse FFT. Our system can interpolate and extrapolate two kinds of motions at any rate, with high accuracy especially in human rotatory movement.
