ZigBee based multi-purpose electronic score design and implementation using EOG

Abstract

This study uses ZigBee wireless sensor network technology to build a Multi-purpose Electronic Score system based on the electro-oculogram (EOG). As a requirement when learning to play a musical instrument the most commonly seen scores are available in paper copies. The disadvantage of the paper music score is that pages must be turned manually by the performer while playing music. An alternative is to prepare a miniaturized copy of the score, but this makes the score difficult to read clearly. Electronic scores have recently become available and are expected to become mainstream in the future due to the rapid growth in ebook readers and tablet PCs. Tracking the upward, downward, leftward, rightward and clockwise/counterclockwise eyeball movements and eye blinking, an amplified, bandpass filtered electro-oculogram (EOG) signal is converted into digital form. This signal is further transmitted through a ZigBee wireless module on which an electronic score program is installed, including the following operating modes; go to the previous/next page, recording, tuning and tempo modes. Detected eyeball movements allow a score to be viewed conveniently while playing. In the future, the proposed technology can be applied to flexible paper, flexible displays and the like.
