Patent ID: 8188968

Claim:
A method for triggering input commands of a program run on a computing system, comprising: identifying a light source within a field of view in front of an image capture device that is located near a display screen, the light source being set to always on during the identifying and pointed toward the image capture device; viewing the light source as it is pointed toward the image capture device, the display screen illustrating objects that can be interacted with; masking pixels not associated with the light source, the masking acting to ignore pixels not associated with the light source, the masking further includes adjusting an amount of light entering the image capture device by adjusting an aperture of the image capture device; detecting a change in light color emitted from the light source, the detecting occurring while the light source is moved in space and tracked; and triggering an input command at the program run on the computing system to initiate an action that can be shown on the display screen, the triggering of the input command occurring in response to the detected change in light color.
