METHODS AND APPARATUSES FOR USE IN CLASSIFYING A MOTION STATE OF A MOBILE DEVICE |
摘要 |
<p>Methods and apparatuses are provided that may be implemented in a mobile device to establish an orientation invariant reference frame based, at least in part, on measurement values from a three-dimensional accelerometer fixed to the mobile device; transform subsequent inertial sensor measurements to the reference frame; and classify a motion state of the mobile device relative to the reference frame based, at least in part, on the transformed inertial sensor measurements.</p> |
