| Research Abstract |
The aims of this research were development of digital archiving of human body motion during dance and numerical analysis on the archived dance motion data. For this purpose we used optical motion capturing system capable of precisely measuring human body motion. The data obtained with the system were subjected to several types of analysis and application programs. The dance body motion data were also used for making computer graphics contents which could be used for educational and publicity purposes. Also, we used representation of dance body motion reproduced by CG for virtual reality environment under the intention of utilizing archived data for new artistic performance.
The result of analysis and representation result of CG and/or VR were fed back to the non-technical researchers such as dance researchers, and dancers, intending acquisition of better analytical results and producing brand new representations. Thus we always considered that the circulation of information between technology and arts was important for obtaining better research results.
As for the categories of dance, we mainly focused on Nihon-buyo and Noh. However we also dealt with African ethnic dances. We also conducted research on general techniques for analyzing human body motion such as segmenting body motion sequence, identifying motions and/or dancers, and retrieving body motion data. We studied the method of extracting characteristic poses and frames from captured motion data, and the method of evaluating the quality of dance body motion based on the Laban motion analysis concept. Besides, by establishing the system and the method of measuring biophysical information such as electromyogram simultaneously with motion capturing, we investigated the difference in motion between expert and novice dancers.
