In the field of dance motion analysis, the development of qualitative evaluation technique for the analysis of body motions described in the form of quantitative data is needed [Nakamura et al. 2008]; it makes dance motion data acquired by motion capture systems intuitively interpretable. In this study, the authors propose a method to automatically summarize the qualitative trend in a group of quantitative dance motion data; the motion features shown in all the dances are first quantitatively extracted by statistical analysis and then qualitatively categorized by cluster analysis.
