摘要

本研究將討論如何使用無線三軸加速度感應器為音樂指揮棒，以此為媒介來進行指揮動作資訊的搜集，我們將分別探討如何分析指揮的動作資訊，辨識指揮者的動作，以及使用無線三軸加速度感應器配合指揮拍法辨識系統間操作的優點。本研究中我們所提出來的系統在判定二拍、三拍以及四拍的指揮法時，平均可以達到90%以上的辨識率！

In this paper, we discuss the use a wireless 3-dimensional acceleration sensor as a conductor's baton such that we can collect the beating data of conducting motion for further analysis. After obtaining the data, we use a similar concept in pitch tracking to analyze the data for recognizing the beat marks. We describe the advantages of using the Wii® remote (which contains a 3-dimensional acceleration sensor) for our conductors’ activity recognition system. While recognizing the beating data which is in two, in three, or in four, the correct percentage can reach up to 90% in average by using our system.
