How is a Nintendo Wii game console able to determine the location of a Wii Remote while a player interacts with a game? The answer is triangulation, a process that determines the location of an object by measuring the angles from two or more fixed points. Surveyors often used triangulation to measure distance. Starting at a known location and elevation, surveyors measure a length to create a baseline and then use a theodolite to measure an angle to an unknown point from each side of the base line (Jains 30-48). The length of the base line and the two known angles allow a computer or person to determine the location of a third point. ¹ Similarly, the Nintendo Wii game console uses triangulation to determine the location of a Wii Remote. A player places a sensor bar, which contains two infrared transmitters, near or on top of a television. While the player uses the Wii Remote, the Wii game console determines the
