Method for compensating for acceleration vector offset, recording medium storing program for executing the method, and related apparatus

A computer-readable recording medium storing a program when executed by a processor perform 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 stable 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.
