Abstract
A system and method of obtaining magnetometer readings for performing a magnetometer calibration are provided. The method comprises detecting initiation of a magnetometer calibration; displaying a plurality of visual elements representing at least a pair of movements, each of the movements orienting a device comprising the magnetometer in substantially opposite positions along a respective axis; and obtaining at least one magnetometer reading during movement of the device. The visual elements may include one in an upright position, one in an upside down position, one facing a first direction and one illustrating the device facing in a second direction. A path may also be defined between the plurality of visual elements using one or more arrows.
