Abstract:
1. An information processing method implemented on a central processing unit or microprocessor to perform information processing in an information processing apparatus that includes the central processing unit or microprocessor the information processing method including steps of: obtaining body motion signal information from a body motion signal formed by an operation in which a subject carries a body motion signal detecting apparatus, the body motion signal detection apparatus being mounted on, connected to, or housed on the subject and having a body motion signal detection section that measures non-invasively and continuously at least a repetitive rhythmic motion of a human body the subject; applying a pattern matching process, in a cycle candidate extracting step, on the body motion signal information, and extracting a rhythm cycle candidate wave as rhythm cycle candidates related to the rhythmic motion; performing −1 or more times integration, in an auxiliary-wave producing step, on the body motion signal information to obtain a motion trajectory, determining a time scale from the motion trajectory, and performing coarse-graining on the motion trajectory by using the time scale of the motion trajectory to produce an auxiliary wave; and superimposing, by implementing the superimposing on the central processing unit or the microprocessor of the information processing apparatus in a cycle selecting step, the rhythm cycle candidate wave, that was extracted in the cycle candidate extracting step, on the auxiliary wave, that was obtained in the auxiliary-wave producing step, and selecting a cycle of the rhythm cycle candidate wave which has a peak in a region surrounded by a peak of the auxiliary wave, as a true cycle.
