Title
(EN) Dynamic magnetometer calibration
Abstract
(EN)

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 calculating updated directional offset data based on the plurality of samples of the magnetic information and on the directional offset data, and 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 the updated directional offset data.
