Abstract
A method for calibrating a device is described. The device accesses magnetometer data of a magnetometer sensor in the device, and accelerometer data of an accelerometer sensor in the device. The device determines a first position and a second position of the device based on the magnetometer data and the accelerometer data. The device determines a first magnetic vector based on the magnetometer data at the first position of the device, and a second magnetic vector based on the magnetometer data at the second position of the device. The device then assigns the first magnetic vector to the first position of the device, and the second magnetic vector to the second position of the device.
