The Whole-Body Coordination of an Expert Calligrapher Actively Changes in Response to The Forms of Characters

Abstract

　This study examines the writing skill of an expert Chinese calligrapher through an evaluation of whole-body coordination. The degree of functional connectivity between the brush tip, the head, and the trunk was evaluated using the cross-correlation function. The results showed that the cal-ligrapher connected the velocity of the brush tip with the trunk. In addition, the degree of connec-tivity between the brush tip and the trunk dynamically changed depending on the form of a Chinese character. The calligrapher has developed whole-body coordination in which trunk segments were actively involved in the brush stroke, depending on the forms of Chinese characters.
