Factor analysis of graceful bow based on skeleton model

This paper considers how the impression of gracefulness one feels from a bow is related to variations in the angles of the human body parts. From the fact that a bow movement is composed of multiple joints and tilting of various body parts, we developed a bow model using a skeleton model and uses it to extract the configuration factor of gracefulness in a bow in order to contribute to its objective evaluation and effective instruction. Using the model, multiple patterns of variations of the angle of the various model parts are examined and the psychological evaluation experiment is conducted on test to investigate the gracefulness.
