Title:
STRESS INFERENCE DEVICE, INFERENCE METHOD, PROGRAM, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/038776
Kind Code:
A1
Abstract:
A stress inference device (100X) mainly comprises a biological signal acquisition means (101X), a biological signal feature amount calculation means (103X), an attribute/pattern data acquisition means (104X), an attribute/pattern common feature amount selection means (105X), and a stress inference means (106X). The biological signal acquisition means (101X) acquires a biological signal of a measurement subject. The biological signal feature amount calculation means (103X) calculates biological signal feature amounts that are feature amounts of a biological signal related to stress. The attribute/pattern data acquisition means (104X) acquires attribute/pattern data that indicates an attribute and/or a pattern of the measurement subject. The attribute/pattern common feature amount selection means (105X) selects, from the biological signal feature amounts, an attribute/pattern common feature amount, which is a feature amount that does not depend on the attribute/pattern indicated by the attribute/pattern data. The stress inference means (106X) infers the stress of the measurement subject on the basis of the attribute/pattern common feature amount.
