Note that ultimately it might not be a "Radio" Drum. The technology might end up being different. It must be a 3-dimensional controller that "doubles" as a drum. That is, it senses the space above a surface, but it also can be played like a drum, and identify "whacks" and different kinds of gestures, bounces, etc. It is a controller, and does not generate sound. The fist-generation Radio Drum was designed by Bob Boie and built at Bell Labs in the mid-1980's as a "three-dimensional mouse." The Radio Drum itself could be called a "gesture sensor" that keeps constant track of the 3-dimensional spatial location of mallets in the following way: A small amount of wire is wrapped around the end of each of two sticks and acts as a conducting surface electrically driven by a radio frequency voltage source. Temporal resolution: 1 millisecond latency Spatial resolution: 1 millimeter resolution in x,y,z 1. 1. written by Dr.
Radio Drum The Radio Drum is an analyzer of gestural data. It is a three- dimensional controller, a sort of computerized musical drum. Invented in the late 1980’s, the Radio Drum uses the “jeu de jacquet” or “Backgammon” form of capacitive sensing to interpret the gestures of a performer. Figure from ATT Bell Laboratory Radio Drum Manual By using a displacement algorithm, the four signals can be transformed into three data channels representing the x,y,z displacement versus time. Various drumming motions can be characterized by the signals generated by the drumsticks versus antennas displacements.
