## Abstract

A reduction in concentration due to a change in an emotion is inhibited. A change in an emotion of the human is suitably reduced. Part (in particular, an eye or an eye and its vicinity) or the whole of a user's face is detected, a feature of the user's face is extracted from data on the detected part or whole of the face, and an emotion of the user is estimated from the extracted feature of the face. In the case where the estimated emotion is an emotion that might reduce concentration, for example, a stimulus is applied to the sense of sight, the sense of hearing, the sense of touch, the sense of smell, or the like of the user to recover the concentration of the user.
