So many computer musicians are bound to the standard keyboard/mouse/monitor interaction model. To provide an engaging performance, musicians need to move beyond that interaction model. The human body is capable of a great range of gestures, large and small. Computer musicians should not be limited to the small set of gestures that normal computer use encompasses. In order to physically interact with the computer, input devices are needed. The first question is how much the musician wants to control at a given time and how much a human is capable of managing at a given moment.
