歩行時のPoint-Light Motionに対する人らしさの要因分析

抄録

Body motions play an important role in human existence and expression. This paper focuses on body cognition by analyzing characteristics of Point-Light displays, the biological motion expressed through point light sources. For the analysis the point’s positions and movements were considered to be significant characteristics. In Experiment 1, we found three significant characteristics: (1) the length between head and foot, (2) head properties, and (3) similarity with a normal motion. In Experiment 2, 30 samples were assessed through qualitative and quantitative methods such as regression analysis to find out which characteristics are important. The result indicates that the important characteristic are combinations of the point’s positions and moving distance as well as direction.
