Abstract

Provided is a display device including a display configured to display first content; a memory storing instructions; and a processor configured to execute the instructions to: obtain first content information by analyzing the first content, obtain user tracking information by tracking a user viewing the first content displayed by the display, determine whether a trigger condition is satisfied, based on at least one of the first content information or the user tracking information, and based on the trigger condition being satisfied, control a communication unit to transmit second content to a projector connected to the display device, wherein the second content is generated based on the first content.

First claim

What is claimed is:

1. A display device comprising:
a display configured to display first content;
a memory storing instructions; and
a processor configured to execute the instructions to:
obtain first content information by analyzing the first content,
obtain user tracking information by tracking a user viewing the first content displayed by the display, the user tracking information comprising position information of the user,
determine whether a trigger condition is satisfied, based on at least one of the first content information and the user tracking information, and
based on the trigger condition being satisfied, control a communication unit to transmit second content to a projector connected to the display device,

wherein the second content is generated based on the first content,
wherein the trigger condition comprises the user tracking information indicating that a gaze of the user has changed from a first gaze in a first direction that is directed toward the display to a second gaze in a second direction that is directed away from the display,
wherein, based on the trigger condition being satisfied, the processor is configured to execute the instructions to control the communication unit to transmit the position information of the user and projection angle information to the projector, and
wherein, based on receiving the position information and the projection angle information from the communication unit, the projector is configured to output the second content at a region corresponding to the second gaze.

2. The display device of claim 1 , wherein the processor is further configured to execute the instructions to, based on the trigger condition being satisfied, control the communication unit to transmit a trigger signal to the projector, and
wherein the trigger signal comprises a first signal for powering on the projector or a second signal for switching the projector to an active state.

3. The display device of claim 1 , wherein the user tracking information further comprises at least one of a number of users, and a posture of the user.

4. The display device of claim 1 , wherein the projector is configured to be rotatable by 360 degrees.

5. The display device of claim 1 , wherein the processor is further configured to execute the instructions to generate the second content by:
performing at least one of extracting, copying, modifying, or composing at least partial content included in the first content, or
recommending content related to the first content as the second content.

6. The display device of claim 1 , wherein the first content information comprises at least one of type information of the first content, genre information of the first content, object information included in the first content, or metadata regarding the first content.

7. The display device of claim 1 , further comprising a camera,
wherein the processor is further configured to execute the instructions to control the camera to track the user.

8. The display device of claim 1 , wherein the processor is further configured to execute the instructions to:
obtain screen configuration information of the display, the screen configuration information of the display comprising at least one of brightness information, resolution information, size information, color information, or contrast information of the display,
determine screen configuration information of the projector based on the screen configuration information of the display, and
control the communication unit to transmit the screen configuration information of the projector to the projector.

9. The display device of claim 8 , wherein the second content is projected based on the screen configuration information of the projector.

10. An method operating of a display device, the method comprising:
displaying first content on a display of the display device;
obtaining first content information by analyzing the first content;
obtaining user tracking information by tracking a user viewing the first content that is displayed, the user tracking information comprising position information of the user;
determining whether a trigger condition is satisfied, based on at least one of the first content information and the user tracking information; and
based on the trigger condition being satisfied, transmitting second content generated to a projector connected to the display device,
wherein the second content is generated based on the first content,
wherein the trigger condition comprises the user tracking information indicating that a gaze of the user has changed from a first gaze in a first direction that is directed toward the display to a second gaze in a second direction that is directed away from the display, and
wherein the method further comprises:
based on the trigger condition being satisfied, transmitting the position information of the user and projection angle information to the projector, and
based on receiving the position information and the projection angle information, outputting, by the projector, the second content at a region corresponding to the second gaze.

11. The method of claim 10 , further comprising transmitting a trigger signal to the projector based on the trigger condition being satisfied,
wherein the trigger signal comprises a signal for powering on the projector or a signal for switching the projector to an active state.

12. The method of claim 10 , wherein the obtaining of the user tracking information comprises obtaining at least one of a number of users, and a posture of the user by tracking the user viewing the first content.

13. A non-transitory computer-readable storage medium storing instructions that are executable by a processor to perform a method of operating a display, the method comprising:
displaying first content on a display of a display device;
obtaining first content information by analyzing the first content;
obtaining user tracking information by tracking a user viewing the first content that is displayed, the user tracking information comprising position information of the user;
determining whether a trigger condition is satisfied, based on at least one of the first content information and the user tracking information; and
based on the trigger condition being satisfied, transmitting second content generated to a projector connected to the display device,
wherein the second content is generated based on the first content,
wherein the trigger condition comprises the user tracking information indicating that a gaze of the user has changed from a first gaze in a first direction that is directed toward the display to a second gaze in a second direction that is directed away from the display, and
wherein the method further comprises:
based on the trigger condition being satisfied, transmitting the position information of the user and projection angle information to the projector, and
based on receiving the position information and the projection angle information, outputting, by the projector, the second content at a region corresponding to the second gaze.

14. The non-transitory computer-readable storage medium of claim 13 , wherein the method further comprises, based on the trigger condition being satisfied, transmitting a trigger signal to the projector, and
wherein the trigger signal comprises a first signal for powering on the projector or a second signal for switching the projector to an active state.

15. The non-transitory computer-readable storage medium of claim 13 , wherein the obtaining of the user tracking information comprises obtaining at least one of a number of users, and
