Qualitative evaluation of quantitative dance motion data

Abstract

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.
