Abstract
Systems and methods for detecting a finger position on the playing surface of an instrument are described. A sensor module located at a selected location of the playing surface emits light that is reflected or diffused by a finger or an object near the selected location. The reflected or diffused light is sensed by the sensor module, which generates a signal indicative of the amount of light detected. Based on the signal, a location of the finger or object is determined. When the finger placement corresponds to a specific note or effect, a digital signal is generated indicating the note or effect.
