Abstract

A display device and an operating method thereof are provided. The display device includes a display unit and a user recognition unit recognizing a user. A control unit in the display device provides a user interface screen corresponding to position relationship between the recognized user and the display device through the display unit.

Claims

1. A display device comprising:

a display unit;

a user recognition unit configured to recognize a user; and

a control unit configured to;

provide a user interface screen corresponding to the position relationship between the recognized user and the display device through the display unit.

2. The display device according to claim 1, wherein the control unit measures a distance between the recognized user and the display device and provides the user interface screen on the basis of the measured distance.

3. The display device according to claim 2, wherein the control unit provides a remote controller-based first user interface screen for controlling an operation of the display device through the remote controller, when the distance between the recognized user and the display device is greater than a first reference distance.

4. The display device according to claim 3, wherein the control unit provides a gesture-based second user interface screen for controlling the operation of the display device through a gesture of the user, when the distance between the recognized user and the display device is smaller than the first reference distance and greater than a second reference distance.

5. The display device according to claim 4, wherein the control unit provides a touch-based third user interface screen through a touch of the user, when the distance between the recognized user and the display device is smaller than the second reference distance.

6. The display device according to claim 2, wherein the control unit provides the user interface screen on the basis of the measured distance and an angle that the user and the display device make.

7. The display device according to claim 6, wherein the controller provides a remote controller-based first user interface screen for controlling an operation of the display device, when the angle between the user and the display device is greater than a reference angle.

8. The display device according to claim 1, wherein the control unit provides the user interface screen on the basis of a connection state with a remote controller for controlling an operation of the display device.

9. The display device according to claim 8, wherein the control unit provides a touch-based third user interface screen, when the display device is disconnected from the remoter controller.

10. The display device according to claim 1, wherein the control unit displays, through the display unit, a notification window for notifying the position relationship between the user and the display device.

11. An operating method of a display device, comprising:

recognizing a user in front of the display device; and

providing a user interface screen corresponding to position relationship between the recognized user and the display device.

12. The operating method according to claim 11, further comprising measuring a distance between the recognized user and the display device, and

wherein the providing of the user interface screen comprises providing the user interface screen based on the measured distance.

13. The operating method according to claim 12, wherein the providing of the user interface screen based on the measured distance comprises providing a remote controller-based first user interface screen for controlling an operation of the display device through the remote controller, when the distance between the recognized user and the display device is greater than a first reference distance.

14. The operating method according to claim 13, wherein the providing of the user interface screen based on the measured distance comprises providing a gesture-based second user interface screen for controlling the operation of the display device through a gesture of the user, when the distance between the recognized user and the display device is smaller than the first reference distance and greater than a second reference distance.

15. The operating method according to claim 14, wherein the providing of the user interface screen based on the measured distance comprises providing a touch-based third user interface screen through a touch of the user, when the distance between the recognized user and the display device is smaller than the second reference distance.

16. The operating method according to claim 12, wherein the providing of the user interface corresponding to the confirmed position relationship comprises providing the user interface screen on the basis of the measured distance and an angle that the user and the display device make.

17. The operating method according to claim 16, wherein the providing of the user interface corresponding to the confirmed position relationship comprises providing a remote controller-based first user interface screen for controlling an operation of the display device, when the angle between the user and the display device is greater than a reference angle.

18. The operating method according to claim 11, further comprising providing the user interface screen based on a connection state with an external device for controlling the operation of the display device.

19. The operating method according to claim 18, wherein a touch-based third user interface screen is provided, when the display device is disconnected from the external device.

20. The operating method according to claim 11, further comprising displaying, through a display unit, a notification window notifying the position relationship between the user and the display device.
