Abstract

A terminal and controlling method thereof are disclosed. While a plurality of terminals are connected to each other by wireless communication, the present invention enable content information included on each screen of first and second terminals to become usable freely and interchangeably.

Claims

1. A method of controlling an external terminal from a terminal, the method comprising:

establishing communication with the external terminal;

receiving screen information from the external terminal, wherein the screen information is displayed in the external terminal;

displaying the screen information as is displayed in the external terminal on at least a portion of a screen of the terminal;

selecting content information from the screen information that is displayed on the at least the portion of the screen of the terminal, wherein the content information exists at recognized location on the at least the portion of the screen of the terminal;

transmitting the location information of the selected content information displayed on the at least the portion of the screen of the terminal to the external terminal; and

receiving the selected content information corresponding to the transmitted location information from the external terminal,

wherein the location information of the selected content information includes coordinates information, and

wherein the coordinates information is relative coordinates of the selected content information in the screen information displayed on the at least the portion of the screen of the terminal.

2. The method of claim 1, further comprising:

storing the received content information.

3. The method of claim 2, wherein the storing step comprising:

distinguishing a type of the received content information; and

storing the received content information according to the distinguished type of the content information.

4. The method of claim 1, further comprising:

when the received content information is selected, driving an application for executing the selected content information; and

executing the content information using the application.

5. The method of claim 1, further comprising:

when the received content information is selected, driving an application for editing the selected content information; and

storing the content information that is edited through the application.

6. The method of claim 5, further comprising:

when the stored content information is dragged and dropped to the at least the portion of the screen of the terminal, transmitting the stored content information to the external terminal.

7. The method of claim 1, wherein, in the content information selecting step, the content information is selected by being dragged and dropped to another portion of the screen other than the at least the portion of the screen of the terminal.

8. The method of claim 1, further comprising:

when the content information that is displayed in the another portion of the screen is selected, transmitting the selected content information to the external terminal.

15. The method of claim 1, further comprising:

receiving location information of a content information on the screen of the external terminal, when the content information is selected from the external terminal;

receiving, from an external server, the selected content information corresponding to the received location information; and

transmitting the received content information to the external terminal,

wherein the selected content information exists on the external server.

16. The method of claim 1, further comprising:

receiving the screen information including a window for receiving the content information from the external terminal, when the content information displayed on the at least the portion of the screen of the terminal is selected.

9. A method of controlling an external terminal from a terminal, the method comprising:

displaying screen information including at least one content information on a screen of the terminal;

establishing communication with the external terminal;

transmitting the displayed screen information to the external terminal; and

when a signal including a location information of the at least one content information displayed on a screen of the external terminal is received from the external terminal, executing a function of the terminal corresponding to the location information of at least one content information,

wherein the location information of the at least one content information includes coordinates information, and

wherein the coordinates information is relative coordinates of the at least one content information in the screen information displayed on the screen of the external terminal.

10. The method of claim 9, wherein the function executing step further comprises:

transmitting execution screen information of the function of the terminal corresponding to the at least one content information to the external terminal.

11. The method of claim 9, wherein the function executing step further comprises:

driving an application for editing the at least one content information corresponding to the location information on the screen of the terminal; and

transmitting edited screen information of the at least one content information edited through the driven application to the external terminal.

12. The method of claim 9, wherein the function executing step further comprises transmitting the at least one content information corresponding to the location information on the screen of the terminal to the external terminal.

13. A terminal, comprising:

a wireless communication unit configured to establish communication with a plurality of external terminals including a first external terminal and a second external terminal, the wireless communication unit is further configured to receive a first screen information displayed on the first external terminal and a second screen information displayed on the second external terminal;

a display unit configured to display the first screen information and the second screen information on a first portion and a second portion on a screen of the terminal, respectively; and

a control unit, when content information displayed within the first portion is selected, the control unit is configured to recognize a location of the selected content information existing on the first portion of the screen of the terminal, to transmit location information of the selected content information to the first external terminal, to receive the selected content information from the first external terminal and to transmit the selected content information to the second external terminal,

wherein the location information of the selected content information includes coordinates information, and

wherein the coordinates information is relative coordinates of the selected content information in the first screen information or the second screen information displayed on the first portion and the second portion on the screen of the terminal.

14. The terminal of claim 13, wherein the wireless communication unit is further configured to establish communication with the first external terminal by a first communication system, to establish communication with the second external terminal by a second communication system, and to transceive data with the first and second external terminals;

and

the control unit is further configured to transmit the data of the first external terminal received via the first communication system to the second terminal using the second communication system, and configured to transmit the data of the second external terminal received via the second communication system to the first external terminal using the first communication system.
