Attaching-music: An interactive music delivery system for private listening as wherever you go
In this paper, we propose a music listening system, called “Attaching-Music,” which detects a human subject's ear position and projects the sound to a listener's ears by two directional speakers with servo motors. Our probabilistic head detection scheme from depth data can provide precise location for speakers to project the sound to an audience. Using the proposed “Attaching-Music” system, a headset-free user can listen to a music with proper soundstage with stereo effect based on two directional speakers driven by the corresponding servo motors, with the 3D localization parameters provided by our head detection scheme in an operational range.
