Abstract: A control device 10 of a robot 2 includes a facial recognition tracking unit 32, a human body tracking unit 33, a person re-identification unit 35, and a determination unit 37. The facial recognition tracking unit 32 executes facial recognition processing and face tracking processing, the human body tracking unit 33 executes human body tracking processing, and the person re-identification unit 35 executes person re-identification processing. Furthermore, when at least one of the facial recognition processing, the film tracking processing, the human body tracking processing, and the person re-identification processing is successful, a determination unit 36 determines that a recognition target person is successfully identified.

Abstract: A carry measuring device includes a first acquiring section configured to acquire a sensor signal from a motion sensor attached to at least one of an exercise instrument and a user, a second acquiring section configured to acquire position information, a shot detecting section configured to detect a shot on the basis of the sensor signal, a position measuring section configured to measure a shot position on the basis of the position information at the time when the shot is detected, and a carry measuring section configured to measure a carry of a hit ball on the basis of the distance between the shot position of the last time and the shot position of this time.

Abstract: An information providing method includes: a physical characteristic information acquisition process of acquiring first physical characteristic information that is information about a physical characteristic of a user; a swing information acquisition process of acquiring, from a detection device which detects a movement in which the user swings a sporting apparatus, first swing information that is information about the swing by the user; an extraction process of extracting, from a storage device that stores other user information in which second physical characteristic information that is information about a physical characteristic of another user and second swing information that is information about a swing by the another user are associated with each other, the other user information on the basis of the first physical characteristic information and the first swing information; and an output process of outputting the other user information that is extracted.
