Claim:
1. 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 only at a control spot identified by color light that is different than, smaller than, and a portion of a size of, the illumination region, wherein the sensor detects a presence of the hand gesture by hand temperature or skin color; a processor that converts data related to the hand gesture at or near the control spot into a command signal; 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 in the control spot; and a control spot generator that generates the control spot for providing a region at a specific position for the hand gesture allowing the sensor to recognize the hand gesture only in the region at the specific position for the hand gesture; and a light source module that outputs the beam of light to the beam steering mechanism for directing the beam of light to at least one of the first surface location and the second surface location, wherein the light source module comprises the control spot generator, and wherein the light source module further comprises a lens, a light source, and a partial filter having a color filtered region and an unfiltered region, wherein the control spot is formed by the color filtered region, the illumination region is formed by the unfiltered region, wherein the partial filter is at a focal plane of the lens, and wherein the control spot provides the region at the specific position for the hand gesture to be recognized as a command corresponding to the command signal.
