BODY MOVEMENT SIGNAL INFORMATION PROCESSING METHOD, INFORMATION PROCESSING SYSTEM AND INFORMATION PROCESSING DEVICE

摘要

Information processing is performed on body movement signal information in an information processing device, the body movement signal information being obtained by the subject's carrying with him/her a body movement signal detection device having a body movement signal detection unit for non-invasively and continuously measuring at least a repeated rhythmic motion of a human body. The results obtained by the information processing are extracted. The information processing includes the following steps (1) to (3): (1) a cycle candidate extraction step of performing a pattern matching process on the body movement signal information and extracting rhythm cycle candidate waves as a rhythm cycle candidate of the rhythmic motion; (2) an auxiliary wave creation step of obtaining a motion trajectory by taking minus one or more time integrals of the body movement signal information and creating auxiliary waves by performing a coarse-graining of the motion trajectory; and (3) a cycle selection step of overlapping the rhythm cycle candidate waves extracted in the cycle candidate extraction step with the auxiliary waves obtained in the auxiliary wave creation step and selecting, as a true cycle, the cycle of rhythm cycle candidate waves having peaks within the auxiliary waves.
