3. A method comprising: automatically detecting a gesture of a body from gesture data received via an optical detector, wherein the gesture data is absolute three-space location data of an instantaneous state of the body at a point in time and space, the detecting comprising aggregating the gesture data, and identifying the gesture using only the gesture data; translating the gesture to a gesture signal; and controlling a component coupled to a computer in response to the gesture signal.
