Patent ID: 8477097

Claim:
A method for controlling a display device, said method comprising: detecting a change in orientation of a housing of a controller, wherein said change in orientation comprises movement of said housing from a first orientation to a second orientation, and wherein said detecting further comprises detecting said change in orientation using at least one accelerometer, wherein at least two vector components of movement are derived from data from the accelerometer generated in response to movement of the housing from the first orientation to the second orientation to thereby determine the second orientation, the first orientation being a position of the housing disposed on a surface of the display device recognized by the controller; generating a signal using said controller responsive to said detecting said change in orientation wherein said signal is based on a position of a line that is computed at least partially by comparing the first and second orientations, the position of the line being such that it extends longitudinally from said controller to intersect a frontal plane of the display device at a location; communicating using a radio transmitter, said signal from said controller to another system for controlling a position of a cursor displayed by the display device to present the cursor at the location.
