EASY-Play / portable musical instrument

“Easy-play” is a set of portable musical instruments for band performance. Each one of the instruments has its own laser projection ports. Through multi-touch system, performers can play the instruments by touching the laser activated strings, keyboard or drum kit projected onto the instrument (as in the rod-shaped one case) or a tabletop. Utilizing touch sensors and touch screens, the instruments can recognize the positions of fingers. In this way, the rod-shaped one functions as a guitar or bass while the other one, with a tabletop, functions as keyboards or a drum kit. Special bottoms are designed for instruments switch and volume control.
