本文提出了两种低成本的，实时的小提琴演奏跟踪方法。低延迟音高检测是通过使用电阻指板的手指位置测量来通知音频分析来实现的;该组合优于仅音频方法。弓的位置和压力是使用放置在弓杆上的四个光学反射传感器来跟踪的，允许在弦的力下测量头发的位移。该系统的两种传感器装置都可以安装在现有的小提琴上，而不会损坏乐器。一个案例研究表明，这些技术的实用性，发现手指和鞠躬注意在性能发作。
This paper presents two low-cost, real-time methods for performance tracking on the violin. Low-latency pitch detection is achieved by using finger position measurements from a resistive fingerboard to inform audio analysis; the combination outperforming audio-only methods. Bow position and pressure are tracked using four optical reflectance sensors placed on the bow stick, allowing the displacement of the hair to be measured under the force of the string. Both sensor arrangements for this system can be fitted to existing violins without damaging the instrument. A case study demonstrating the utility of these techniques is presented finding fingered and bowed note onsets during performance.
