袈裟斬り動作の体性感覚に基づく主観評価と運動計測に基づく客観評価

摘要

This paper presents a comparison between subjective andobjective evaluations based on so-matic sensation and motion capture, respectively. We chose diagonal cutting 'kesagiri'motion as an example and compared the self evaluation with the kinematic analysis of the measured sword trajectory . In our experiments, subjective evaluations showed qualitatively good correspondence with the numerical evalua-tions. This result indicates that we can use external observation for extimating somatic sensations,instead of conventional methods such as questionnaires which inherently contain ambiguity and uncertainty.
