Electric music baton system
We are developing an electronic baton system as an alternative haptic interface to facilitate music lessons for the visually impaired. This system incorporates an acceleration sensor in the baton, transmits data to a player via radio signals, and acts as a haptic interface by generating vibrations. In this paper, we experimentally evaluate responses to the stimulus of the visual and the tactile senses in order to verify that a haptic interface can substitute for vision in scenarios that involve real-time tasks, such as music lessons. In the first experiment, we verify that clue motions are important for both the visual and a tactile senses. Next, we test the new method of communicating strength. Thismethod uses not vibration strength but oscillating time for vibrations of the haptic device. The results of the experiment confirm that the technique is effective.
