Smart Technology

A laser music system has been created, that combines a laser and light sensor system with an infrared distance sensing system that detects the position of user’s hand when it intersects one or more of the individual laser beam. The laser beam, which are made visible by a small amount of smoke in a dark room, provides vision, guidance to the user to reduce the difficulty of using a non-contact instrument as well as enhancing an appealing optical effect for the user. The system uses a number of sharp distance sensors to map the position of the users hand to a variable like pitch. The user should move their hand to different heights to achieve a desired pitch. The laser beam should be broken to trigger the desired note.
