Dynamic magnetometer calibration

Реферат: Embodiments related to calibrating a game controller including a magnetometer during game play are disclosed. One embodiment provides a method comprising sampling magnetic information received from the magnetometer, and outputting, to a computing device, an initial game controller orientation signal derived from a first sample of a plurality of samples of the magnetic information and from directional offset data. The method further comprises identifying a valid minimum observed value and a valid maximum observed value from the plurality of samples of the magnetic information, and calculating updated directional offset data based on the valid minimum observed value and the valid maximum observed value. The method further comprises outputting to the computing device a calibrated game controller orientation signal derived from a second sample of the plurality of samples of the magnetic information and from the updated directional offset data.
