<p>Disclosed is a novel technique for generating a reference value for correction of measurement error during user movement. Based on the local coordinate speed vector calculated by a local coordinate speed vector calculation section (21) and the attitude angle that is calculated by an attitude angle calculation section (25), the change portion of the previous detected value, which is similar to the change of the detected value resulting from user movement during detection of attitude and speed, is extracted by performing a prescribed correlation calculation by a correlation calculation section respectively provided with a reference speed vector calculation section (23) and a reference attitude angle calculation section (27). Then, using this extracted result, a reference value of the detected value when the detected value is corrected is calculated and generated by the reference speed vector calculation section (23) and reference attitude angle calculation section (27).</p> |
