Wearable device and behavior evaluation system

Abstract

Provided is a wearable device and a behavior evaluation system that are capable of measuring and evaluating a direct relationship between a wearer and a target person and making the wearer aware, etc., of behavior by clearly indicating an evaluation result. They also contribute to the Sustainable Development Goals (SDGs) of 'health and well-being for all' by enabling maintenance of people's mental and physical health. A wearable deviceis provided with: an imagergenerating a subject image of a target person; a distance measurermeasuring a distance to the target person and obtaining distance data; a subject image processor processing a subject image so as to assign the wearer an expression evaluation score based on face expression obtained by recognizing a face of the target person in the subject image; a distance image processor obtaining the distance to the target person by analyzing a distance image to which the distance data has been mapped, and obtains a distance evaluation score corresponding to the distance; and an output processor performing an evaluation process for obtaining a behavior evaluation score evaluating the wearer's behavior from the expression evaluation score, the distance evaluation score, and the evaluation time of the wearer's behavior, and outputs the behavior evaluation score.
