Abstract: A display apparatus includes an infrared outputter configured to output infrared light toward a user, an image capturer configured to photograph the user to generate a captured image, and a controller configured to detect, from the captured image, a pupil and an iris of the user, and a glint area generated by the infrared light, and to determine, in response to the pupil, the iris, and the glint area being detected, a direction of the user's gaze based on a relation between a location of the pupil, and the glint area, and a size of the iris.
