Abstract: An information processing method includes the following steps: applying a pattern matching process on the body motion signal information, and extracting rhythm cycle candidate waves which are rhythm cycle candidates related to the rhythmic motion; performing ?1 or more times integration on the body motion signal information to obtain a motion trajectory, and performing coarse-graining on the motion trajectory to produce an auxiliary wave; superimposing the rhythm cycle candidate waves which are extracted in the process of extracting the cycle candidate waves, on the obtained auxiliary wave, and selecting a cycle of a rhythm cycle candidate wave which has a peak in the auxiliary wave, as a true cycle; and finally obtaining a result of the processing.
