Patent ID: 8139059

Claim:
A system for illuminating a portion of a display based on real light conditions of a real light source, the system comprising: a computer display device; a light detection device, wherein the light detection device is configured to detect the real light conditions from the real light source that are located externally from the computer display device; a processor; and a memory having computer-executable instructions stored thereon, wherein the computer executable instructions are configured for: receiving data associated with the real light conditions from the real light source, wherein the data is received from the light detection device and indicates a position of the external real light source; obtaining a display position of a graphical object that is displayed on the computer display device; causing the processor to calculate a position of the real light source relative to the display position of the object that is displayed on the computer display device, wherein the position of the real light source is calculated based on a light differential across a length of the computer display device that is detected by the light detection device; and causing the processor to change an illumination of only a portion of the computer display device proximal the display position of the object such that a shadow is displayed on the computer display in relation to the position of the real light source relative to the graphical object, wherein the shadow that is displayed on the computer display changes when the position of the real light source relative to the display of the graphical object, wherein the illumination position and intensity are based on the calculated position of the real light source relative to the obtained position of the graphical object associated with the computer display device; wherein the illumination changes a display of the graphical object on the computer display device.
