在本文中，我们构建了一个系统来实现舞者通过舞蹈演奏音乐的新舞蹈表演风格。通过试点研究，我们发现舞蹈表演的动作识别需要与背景音乐（BGM）同步。因此，我们提出了一种专门针对舞蹈表演的新动作识别方法。该方法的关键技术是（1）自适应决策识别窗口的大小以识别与BGM同步的运动，以及（2）两阶段（粗略和详细）运动识别以实现高速识别的准确性。使用安装在两只鞋上的三轴无线加速度计记录数据。我们在 5 个不同舞步（每个舞步重复 100 次）的数据集上评估了该方法。结果表明，该方法能够提高所有舞步的识别率（在一种情况下将识别率从 62% 提高到 99%），同时保留动作和声音之间的无缝连接感。
In this paper, we constructed a system for realizing a new style of dance performance that dancers play music by dancing. From pilot study, we have found that the motion recognition for dance performance needed the synchronism to back ground music (BGM). Therefore, we propose a new motion recognition method specialized to dance performances. The key techniques of the proposed method are (1) adaptive decision of the size of recognition window to recognize a motion in sync with BGM, and (2) motion recognition in two-phase (rough and detailed) to fulfill the accuracy in high speed recognition. Data was recorded using a 3-axis wireless accelerometers mounted on both shoes. We evaluated the method on a dataset of 5 different dance steps (each repeated 100 times).The results show that this method is capable of improving recognition for all steps (in one case improving recognition from 62% to 99%) while retaining a feeling of seamless connection between movement and sound.
