SEQUENTIAL ATTITUDE IDENTIFICATION DEVICE, AUTONOMIC NERVE FUNCTION INFORMATION ACQUISITION DEVICE, METHOD, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To detect an attitude and a motion state of a subject for health care and disease prevention.SOLUTION: A wearable apparatus that a subject wears is provided with an acceleration information measuring part for measuring acceleration information, and a biological signal information measuring part for measuring biological signal information of the subject. A first feature amount corresponding to a first predetermined period and a second feature amount corresponding to a second predetermined period are extracted from the measured acceleration information and biological signal information. A motion/quiescence identification model, a motion identification model, and a quiescence identification model of the subject are created by machine learning based on the first feature amount. An attitude and motion of the subject are identified by integrating determination results based on each identification model. Correspondence information is created that associates the identified attitude and motion with the biological signal information of the subject.SELECTED DRAWING: Figure 1
