Abstract
An electronic device utilizing a nine-axis motion sensor module, capable of accurately outputting a resultant deviation including deviation angles in a 3D reference frame is provided. The present invention provides a novel comparison and compensation to accurately obtain a resultant deviation including deviation angles of the electronic device under the presence of external and/or internal interferences including the ones caused by undesirable electromagnetic fields and the ones associated with undesirable external forces and axial accelerations. The output of the nine-axis motion sensor module of the present invention including a rotation sensor, an accelerometer and a magnetometer can be advantageously obtained and compensated with a comparison comparing different states of the motion sensor module such that an updated state associated with the output and the resultant deviation angles of the nine-axis motion sensor module are preferably obtained in an absolute manner with the undesirable external interferences being effectively excluded.
