providing a second screen including the recommended application and content.

10. The method of claim 9 , wherein, in the artificial intelligence training model, the information regarding communication between the first device and the second device is analyzed to identify content viewing history information and application use history information; weights are assigned to content and applications based on content viewing periods, a number of times of viewing the content, types of the content, genres of the content, periods of use of the applications, a number of times of use of the applications, and types of the applications; and the recommended application and content are determined based on the assigned weights.

11. The method of claim 1 , further comprising:

receiving, from the first device, information regarding a plurality of devices connected to the first device;

determining at least one of an application or content to be recommended, using information regarding the first device and the information regarding the plurality of devices; and

providing a screen including the determined at least one recommended application or content.

12. The method of claim 1 , further comprising:

establishing communication with a third device located in the available zone;

receiving, from the third device, connection information between the third device and a fourth device connected to the third device;

identifying whether the fourth device is located in the available zone based on the connection information between the third device and the fourth device; and

providing the customized screen based on information regarding a plurality of devices identified as being located in the available zone.

13. The method of claim 12 , further comprising:

obtaining an artificial intelligence training model based on a result of learning a relationship between the first, second, third and fourth devices based on information regarding communication between the first, second, third and fourth devices;

determining an application and content to be recommended based on a common interest between the first, second, third and fourth devices using the obtained artificial intelligence training model; and

providing the customized screen including the recommended content and application.

14. A non-transitory computer-readable recording medium storing a program for implementing the method of claim 1 .

15. A display apparatus comprising:

a display providing a screen customized for a user;

a communicator comprising communication circuitry configured to communicate with a device located in an available zone, the available zone being a range in which content of the display apparatus is viewable;

a processor; and

a memory storing instructions executable by the processor,

wherein the processor is configured to, by executing the instructions, control the display apparatus to:

establish communication with a first device located in the available zone,

receive, from the first device, connection information between the first device and a second device connected to the first device,

determine whether the second device is located in the available zone based on the connection information between the first device and the second device, and

provide a customized screen based on determining that the second device is located in the available zone.

16. The display apparatus of claim 15 , wherein the processor is further configured to, by executing the instructions, control the display device to:
