1. A method for compensating for an acceleration vector offset of an acceleration detector adapted to output measured acceleration values for at least two orthogonal axes, the method comprising:

  • determining whether the acceleration detector is in a stable resting state by evaluating measured acceleration vectors obtained during a first time period, wherein the measured acceleration vectors are calculated using the measured acceleration values;

    if the acceleration detector is determined to be in a stable resting state, then determining whether any one of the at least two orthogonal axes is a main axis using the measured acceleration values; and

    , if the acceleration detector is determined to be in a steady resting state and one of the at least two orthogonal axes is determined to be a main axis, performing an acceleration vector compensation operation to compensate for the acceleration vector offset of the acceleration detector.
