Patent ID: 8689145

Claim:
A system coupled to a display, the system comprising: at least one predetermined light source; a photodetector that detects light from the at least one predetermined light source; a remote control having a relative motion sensor; and at least one controller configured to: detect an initial absolute position of the remote control in a first axis based on the light detected by the photodetector; generate signals for rendering at least a portion of an initial image defined by second and third orthogonal axes on the display, wherein the first axis is orthogonal to the second and third axes, and wherein the initial image is scaled to an initial size corresponding to the initial absolute position; detect an updated absolute position of the remote control in the first axis based on a change in position of the remote control detected by the relative motion sensor and based on the initial absolute position; scale the initial image to a new size corresponding to the updated absolute position; and generate signals for rendering at least a portion of the scaled image on the display.
