概要/Abstract

Fingering is one of important aspects in piano performances because it affects pianists' musicality. On the other hand, we cannot acquire enough samples of actual fingering information. If audience, especially pianists, share the real-time fingering of the performer in a concert, they feel sense of togetherness and it helps them for learning professional piano performances. In response to these requirements, the goal of our study is to construct a real-time fingering detection system for pianists. Our system achieves the real-time fingering detection by integrating a simple camera-based image detection and musical rules. We have developed a prototype system, and evaluated its effectiveness by actual use of the system.
