Automatic score turning system by nodding motion combined with gaze analysis

Abstract

This study examined a method for discriminating players’ page turning cues against head shaking motions for the purpose of developing an automatic page turning system for music scores. Nodding is commonly used as a page turning cue in actual piano playing and has been used in our proposed system. Since a similar motion is made when pianists shake head in time to the music, it is necessary to discriminate page turning cues from this head shaking motion. Through the experimental results, we noticed that displacement of player’s nose position in head shaking motion is shallower than that in page turning cue. Thus we added thresholding processing by using a slider on the software, and used gaze analysis together. It responded only when player gazed in the lower region of the musical score.
