Abstract
Systems, methods and articles of manufacture relating to calibration of a magnetometer in an electronic device suitable for use in an augmented reality (AR) and/or virtual reality (VR) video game. An electronic video game device includes a magnetometer. A prompt is displayed in the video game requesting a user-performed first gameplay motion using the electronic video game device where the first gameplay motion is a pre-defined motion used for calibrating the magnetometer. A first plurality of measurements is received from the magnetometer relating to a magnetic field in a physical gameplay environment, where the first plurality of measurements is taken by the magnetometer during the first gameplay motion. The first plurality of measurements is analyzed to detect a magnetic bias in the magnetometer. The magnetometer is calibrated to offset the magnetic bias.
