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.

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.

A multi-spectral flashlight camera, comprising:
- a pyramid mirror;
- a light source;
- two or more focal plane array (FPA) devices, each operating in a different light wave spectrum;
- an aperture lens shared by the light source and the FPA devices at a foci of the lens, wherein light from the light source exits the aperture lens and illuminates a target, wherein reflected and emitted light from the target enters the aperture lens, wherein the pyramid mirror divides the received light so that a percentage of the received light enters an FPA device of the two or more FPA devices, and wherein the illumination area relates to an image corresponding to the FPA devices;
- and
- processing electronics for image acquisition and processing.

A multi-spectral flashlight camera, comprising:
- a pyramid mirror;
- an LED light source;
- a visible channel;
- an uncooled thermal channel;
- an aperture lens that is shared by the light source, the visible channel, and the uncooled thermal channel at a foci of the lens, wherein light from the light source exits the aperture lens and illuminates a target, and wherein the visible image is provided of the illuminated target, and wherein the thermal image is provided of the self-emission target;
- and
- processing electronics for image acquisition and processing.

A method of controlling a light-emitting device, comprising:
- generating a control spot in an illumination region, the illumination region positioned at a first surface location;
- determining a hand gesture made at the control spot;
- and
- moving the illumination region to a second surface location in response to the hand gesture.
The method of claim 51, wherein the hand gesture includes a first hand gesture that activates the light-emitting device in a first state, and a second hand gesture that generates a command to move the illumination region to the second surface location.
A smart lamp, comprising:
- a light source module that provides light for an illumination region at a surface location;
- a control spot generator that generates a control spot for positioning in the illumination region and controlling the lamp;
- a sensor that recognizes a hand gesture at the control spot;
- and
- a processor that converts data related to the hand gesture into a command signal for moving the illumination spot to a different surface location and controlling the lamp.
A method for hand gesture recognition, comprising:
- providing an illumination region at a first surface location;
- presenting a control spot at the illuminated surface region;
- positioning a hand at the control spot;
- detecting a presence of the hand at the control spot;
- generating a control signal corresponding to a gesture of the hand;
- moving the illumination region to a second surface location response to the command signal;
- and
- controlling a state of a lamp presenting the control spot.
