The first information processing device has a function of acquiring a first moving image including a face, and detecting eyes from two or more first images included in the first moving image. Further, the first information processing device has a function of detecting the pupil from the eyes detected from the first images, calculating the size of the pupil, and performing learning by using the change in the size of the pupil over time. The second information processing device has a function of acquiring a second moving image including a face, and detecting eyes from two or more second images included in the second moving image. Further, the second information processing device has a function of detecting the pupil from the eyes detected from the second image, calculating the size of the pupil, and inferring the change in the size of the pupil over time on the basis of the results of the learning performed by the first information processing device.
