Abstract
A keyless synthesizer t can stimulate all three senses (hearing, muscle movement and visual) at once in patients born with C.H.A.R.G.E. syndrome while they play and, at the same time, enjoy and have fun with the device. A keyless synthesizer operational by a single hand of the user includes an ultrasound range sensor responsive to the distance “d” of a user's hand from the sensor for generating a sensor signal corresponding to the distance “d”. A programmable microcontroller programmed to convert the sensor signal to one of a plurality of discrete signals. A synthesizer is responsive to each discrete signal for generating a discrete tone. A multi-color generator is responsive to each discrete signal for generating a discrete color so that for each discrete signal corresponding to a distance “d” both a discreet tone and an associated discreet color are generated.
