Abstract
Provided is a light-emitting device control system, comprising a beam steering mechanism that directs a beam of light at a first surface location, wherein an illumination region is formed at the first surface location in response to the directed beam of light, a sensor that recognizes a hand gesture at the illumination region; a processor that converts data related to the hand gesture into a command signal, and a controller that instructs the beam steering mechanism to move the illumination region to a second surface location in response to the command signal corresponding to the hand gesture.
