Visualizing the center of gravity of performers of Nihon Buyo and others,and organizing and verifying the dance education program.

为了给刻苦自学《日本舞》的年轻表演者提供教育支持，我们试图从稳定性和重心位置方面分析他们的动作。这些因素是判断一个人的日本步舞技巧的基础。利用动作捕捉和测力板，我们分析了舞者的重心和压力中心之间的关系。结果表明，对于臀部稳定的表演者，其重心垂直方向的标准差较小。前/后、左/右方向的重心和压力中心的差异也很小。我们还将我们的原始分析应用于有用的教育支持系统的开发，包括一个专注于表演者实现重心的可视化系统，以及一个使用伺服执行器和3D计算机图形的运动指导系统。

To provide educational support for young performers diligently self-studying Nihon Buyo, we sought to analyze their movements in terms of stability and placement of their center of gravity.These factors serve as the basis for judging the skill of one's Nihon Buyo techniques.Using motion capture and force plates, we analyzed the relationship between the dancers' center of gravity and center of pressure.The results revealed that for performers whose hips were stable, the standard deviation of the vertical direction of their center of gravity was small.Differences between the center of gravity and center of pressure in the front/back and left/right directions were also small.We also applied our original analysis to the development of useful educational support systems, including a visualization system that focuses on the center of gravity achieved by the performer and a movement instruction system that uses servo actuators and 3D computer graphics.
