Abstract
Provided is a light-emitting device control system, comprising: a light source module that outputs a beam of light at a first surface location; a beam steering mechanism, the light source module coupled to the beam steering mechanism for directing the beam of light at the first surface location, wherein an illumination region is formed at the first surface location in response to the directed beam of light; a control module that detects a signal corresponding to a hand gesture, the control module positioned at a separate location than the light source module and the beam steering mechanism, and communicating with the light source module via a network; and a control spot generator that generates a control spot at a second surface location, the control module detecting a presence of a hand forming the hand gesture at the control spot, and wherein the beam steering mechanism moves the illumination region in response to the hand gesture at the control spot.
