Original Abstract Submitted
An estimation device () includes a data acquisition unit (), a first smoothing processing unit (), a second smoothing processing unit (), a calculation unit (), and an estimation unit (). The data acquisition unit () acquires time-series data of a pupil diameter during work of a subject of work performance estimation. The first smoothing processing unit () smooths the acquired time-series data of the pupil diameter of the subject by a first time window. The second smoothing processing unit () smooths the time-series data of the pupil diameter by a second time window that is a time window larger than the first time window. The calculation unit () calculates a difference between the time-series data of the pupil diameter smoothed by the first time window and the time-series data of the pupil diameter smoothed by the second time window. The estimation unit () estimates the level of work performance of the subject on the basis of the calculated magnitude of the difference, and outputs a result of the estimation.
