REFERENCE VALUE GENERATING METHOD AND REFERENCE VALUE GENERATING DEVICE

摘要

Based on a local coordinate velocity vector calculated by a local coordinate velocity vector calculation unit and an attitude angle calculated by an attitude angle calculation unit, a change portion of a detected value in the past that is similar to a change in a detected value of attitude and velocity during movement of the user is extracted as a correlation calculation unit provided in each of a reference velocity vector calculation unit and a reference attitude angle calculation unit carries out predetermined correlation calculation. Then, a reference value of the detected value used when correcting the detected value is calculated and generated by the reference velocity vector calculation unit and the reference attitude angle calculation unit, using the result of the extraction.

1. A reference value generating method comprising:
storing a detected value of one of attitude, velocity, angular velocity, and acceleration detected during movement of a user, in a storage unit; extracting a change portion of the detected value in the past that is similar to a change in the detected value up to the present, from the storage unit; and generating a reference value of the detected value used when correcting the detected value, by using a result of the extraction.
