Comparison of Structural Variables with Spatio-temporal Variables Concerning the Identifiability of Okuri Class and Player in Japanese Traditional Dancing

This paper experimentally examined the characteristics of structural variables and spatio-temporal variables through the identifiability of Okuri classes and players (dancers) in traditional Japanese dancing. The data for the experiment were acquired using a motion capture system, which monitored dancing motions performed by a master player (dancer) followed by two expert dancers and three beginners. The discrimination of two Okuri classes, feminine Okuri and descriptive Okuri, and that of 5 dancers was experimentally attempted using structural variables and spatio-temporal variables. The experimental result suggested that spatio-temporal variables were more advantageous than structural variables for identification of Okuri classes and dancers
