Abstract

A mobile terminal including a wireless communication unit configured to wirelessly communicate with at least one other terminal; a display unit configured to display screen information in a first region, and display an indicator area in a second region adjacent to the first region; and a controller configured to extract at least one keyword data included the displayed screen information, perform a search operation using the extracted keyword data, and display a result of the search operation in the second region.

Claims

1. A mobile terminal, comprising:

a wireless communication unit configured to wirelessly communicate with at least one other terminal;

a display unit configured to display screen information in a first region, and display an indicator area in a second region adjacent to the first region, wherein the screen information displayed in the first region includes a plurality of messages exchanged between the mobile terminal and the at least one other terminal via the wireless communication unit; and

a controller configured to;

extract at least one keyword data from the plurality of messages included in the screen information displayed in the first region,

perform a search operation using the extracted keyword data,

display a result of the search operation in the second region,

display a first status display line displayed with the status information of the mobile terminal and a second status display line different from the first status line to be overlapped in the second region, and

change an order in which the first and the second status display lines are overlapped based on a touch input to the second region.

2. The mobile terminal of claim 1, wherein the controller is further configured to:

display an icon corresponding to an intelligent agent (IA) used to perform the search operation in the second region,

receive an input selecting the displayed icon, and

perform the search operation and display the result of the search operation when the icon is selected.

3. The mobile terminal of claim 1, further comprising:

a microphone configured to receive a voice input to perform the search operation, and

perform the search operation and display the result of the search operation when the voice input is received through the microphone.

4. The mobile terminal of claim 3, wherein the controller is further configured to display an icon corresponding to an intelligent agent (IA) used to perform the search operation in the second region when the voice input is received.

5. The mobile terminal of claim 1, wherein the controller is further configured to:

select at least a first message from the messages displayed in the first region,

extract at least one keyword data from the first message,

perform the search operation using the extracted keyword data from the first message, and

display the result of the search operation in the second region.

6. The mobile terminal of claim 5, wherein the controller is further configured to extract said at least one keyword data from the first message based on how frequent a keyword has been used in previous messages.

7. The mobile terminal of claim 5, wherein the controller is further configured to:

select a second message from the messages displayed in the first region,

extract at least one keyword data from the second message,

perform the search operation using the extracted keyword data from the second message, and

selectively display the result of the search operation in the second region for the first and second messages.

8. The mobile terminal of claim 7, wherein the first and second messages are from the at least one other terminal.

9. The mobile terminal of claim 3, wherein after the controller performs the search operation using the extracted keyword data and displays the result of the search operation in the second region, the controller is further configured to receive the voice input, convert the received voice input into text data, extract at least one keyword from the text data, perform an additional search operation using the extracted keyword data and selectively display the result of the additional search operation in the second region.

10. The mobile terminal of claim 2, wherein when the icon is selected, the controller is further configured to display an input window and a virtual keypad for inputting text data on the display unit, and display the input window and the virtual keypad with a same color as that of the icon.

11. The mobile terminal of claim 1, wherein the controller is further configured to receive a touch input of the search result displayed in the second region, insert the search result into a message, and send the message with the search result to the at least one other terminal.

12. The mobile terminal of claim 1, wherein the screen information displayed in the first region includes a plurality of messages exchanged between the mobile terminal and a plurality of other terminals, and

wherein when a counterpart of another terminal is performing the search operation, the controller is further configured to output a notification signal indicating the counterpart is performing the search operation.

13. A method of controlling a mobile terminal, the method comprising:

allowing, via a wireless communication unit, wireless communication with at least one other terminal;

displaying, via a display unit, screen information in a first region, and displaying an indicator area in a second region adjacent to the first region, wherein the screen information displayed in the first region includes a plurality of messages exchanged between the mobile terminal and the at least one other terminal via the wireless communication unit;

extracting, via a controller, at least one keyword data from the plurality of messages included in the screen information displayed in the first region;

performing, via the controller, a search operation using the extracted keyword data;

displaying, via the display unit, a result of the search operation in the second region;

displaying, via the display unit, a first status display line displayed with the status information of the mobile terminal and a second status display line different from the first status line to be overlapped in the second region; and

changing, via the controller, an order in which the first and the second status display lines are overlapped based on a touch input to the second region.

14. The method of claim 13, further comprising:

displaying, via the display unit, an icon corresponding to an intelligent agent (IA) used to perform the search operation in the second region;

receiving an input selecting the displayed icon; and

performing, via the controller, the search operation and display the result of the search operation when the icon is selected.

15. The method of claim 13, further comprising:

receiving, via a microphone, a voice input to perform the search operation; and

performing, via the controller, the search operation and display the result of the search operation when the voice input is received through the microphone.

16. The method of claim 15, further comprising:

displaying, via the display unit, an icon corresponding to an intelligent agent (IA) used to perform the search operation in the second region when the voice input is received.

17. The method of claim 13, wherein the screen information displayed in the first region includes a plurality of messages exchanged between the mobile terminal and the at least one other terminal, and

wherein the method further comprises:

selecting at least a first message from the messages displayed in the first region;

extracting at least one keyword data from the first message;

performing the search operation using the extracted keyword data from the first message; and

displaying the result of the search operation in the second region.

18. The method of claim 17, further comprising:

extracting, via the controller, said at least one keyword data from the first message based on how frequent a keyword has been used in previous messages.
