Patent ID: 8821281

Claim:
A method, comprising: determining, via a processor, screen plane coordinates that define a planar orientation of a game display screen relative to a location of a game sensor, where the game sensor is located outside of an area between a user and the game display screen, comprising: causing at least one audible signal generator to generate an audible signal at each of at least three locations within a two-dimensional area along a plane of the game display screen during game play configuration processing; detecting each of the audible signals generated at each of the at least three locations within the two-dimensional area along the plane of the game display screen; calculating a distance of each of the detected audible signals from the game sensor based upon a time difference between a signal generation time of each audible signal and a signal detection time of each audible signal; calculating each screen plane coordinate that defines the planar orientation of the game display screen using one of the calculated distances of the detected audible signals; identifying two intersecting lines that each pass through two of the calculated screen plane coordinates; and defining the planar orientation of the game display screen as a plane created by the two intersecting lines relative to the location of the game sensor; determining a location of the user relative to the location of the game sensor; and calculating an orientation of the user relative to the planar orientation of the game display screen based upon the determined screen plane coordinates that define the planar orientation of the game display screen relative to the location of the game sensor and the determined location of the user relative to the location of the game sensor.
