  • Publication number: 20240065600
    Abstract: An emotion estimating device, an emotion estimating system, and an emotion estimating method capable of estimating an emotion of a subject based on information obtained from daily activities can be provided. An emotion estimating device includes an interface that receives input of walking data of a subject measured by a measurement device and emotion data obtained by quantifying the emotion of the subject, a storage that stores the walking data and the emotion data, and an computer that obtains corresponding data in which a plurality of walking parameters included in the walking data stored in the storage are associated with the emotion data. When the interface newly receives the input of the walking data, the computer estimates the emotion of the subject from the plurality of walking parameters included in the newly received walking data, and outputs information indicating the estimated emotion of the subject.
