Classification: CPC G | IPC G

Claim 11:
12. A display device comprising:
a transparent screen;
a sensor configured to recognize an object in front of the transparent screen and an object behind the transparent screen; and
at least one processor configured to:
receive a position of a user in front of the transparent screen and an eye gaze of the user looking at the transparent screen, which are recognized by using the sensor,
receive a position of a background object behind the transparent screen, which is recognized by using the sensor,
detect 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,
determine, 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,
and
display, 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,

wherein the at least one processor is further configured to:
when the user moves, predict the eye gaze changing according to a movement speed of the user, and
move 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 is 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.
