1. A method of controlling a display device including a transparent screen, the method comprising:
recognizing a position of a user in front of the transparent screen and an eye gaze of the user looking at the transparent screen;
recognizing a position of a background object behind the transparent screen;
detecting a change from a first eye gaze with which the user looks at a first point, to a second eye gaze with which the user looks at a second point;
determining, as a minimum angular change of an eye gaze, a minimum angle by which the change between the first eye gaze and the second eye gaze is detected;
displaying, on the transparent screen, information related to the background object, when the background object is at a position within the minimum angular change of the eye gaze from a current eye gaze of the user; and
when the user moves, predicting the eye gaze changing according to a movement speed of the user, and moving the related information such that the related information is displayed at a position on the transparent screen out of the minimum angular change of the eye gaze from the current eye gaze of the user,
wherein, a probability distribution of the first point and a first entire area is determined,
wherein the first point is a point that the user at a current distance from the transparent screen is most likely looking at, and the first entire area an area that the user is likely looking at, and
wherein the second point and a second entire area are determined according to the probability distribution, the second point is a point that the user is most likely looking at after a preset time period T, and the second entire area is an area that the user is likely looking at after the preset time period T.
