SEQUENTIAL POSTURE IDENTIFICATION DEVICE AND AUTONOMIC FUNCTION INFORMATION ACQUISITION DEVICE, METHOD, AND PROGRAM

摘要

In a wearable device attached to a subject, an acceleration information measurement unit that measures acceleration information, and a biological signal information measurement unit that measures biological signal information of the subject, are provided. From the measured acceleration information and biological signal information, first feature data corresponding to a first predetermined period and second feature data corresponding to a second predetermined period are extracted. By machine learning based on the first feature data, a dynamic/static activity identification model, a dynamic-activity identification model, and a static-activity identification model, for the subject, are generated. By combination of results of determination based on each of the identification models, a posture and an activity of the subject are identified. Correspondence information, which associates the identified posture and activity with the biological signal information of the subject, is generated.
