Abstract

A mobile terminal including a touch screen, and a controller configured to designate a plurality of areas on the touch screen, each area including text information, receive a multi touch action on the touch screen, select a specific area from the plurality of designated areas regardless of areas touched in the multi touch action, determine at least one touch in the multi touch action is moving, and adjust a magnification rate of the text information included in the selected specific area in correspondence with the at least one touch moving.

Claims

1. A mobile terminal, comprising:

a touch screen; and

a controller configured to;

designate a plurality of areas on the touch screen, each area including text information,

receive a multi touch action on the touch screen,

select a specific area from the plurality of designated areas regardless of areas touched in the multi touch action,

determine at least one touch in the multi touch action is moving, and

adjust a magnification rate of the text information included in the selected specific area in correspondence with the at least one touch moving.

2. The mobile terminal of claim 1, wherein the controller is further configured to determine at least one of the touches in the multi touch action is released, and to apply the magnification rate that was adjusted before the at least one of the multi touches was released to all of the plurality of designated areas.

3. The mobile terminal of claim 1, wherein the controller is further configured to determine at least one of the touches in the multi touch action is released, and to apply the magnification rate that was adjusted before the at least one of the multi touches was released only to the selected specific area.

4. The mobile terminal of claim 1, wherein the controller is further configured to determine at least one of the touches in the multi touch action is released, and to apply the magnification rate that was adjusted before the at least one of the multi touches was released to information displayed on the touch screen other than the plurality of designated areas.

5. The mobile terminal of claim 1, wherein the controller is further configured to fix the magnification rate of text information included in an area other than the specific area, while adjusting the magnification rate of text information included in the specific area in response to the at least one touch moving.

6. The mobile terminal of claim 1, wherein the controller is further configured to select a specific area that matches a predetermined reference from among a plurality of different references that exclude the areas touched in the multi touch action.

7. The mobile terminal of claim 1, wherein the controller is further configured to dim an area other than the specific area, while adjusting the magnification rate of the text information included in the selected specific area.

8. The mobile terminal of claim 1, wherein after selecting the specific area, the controller is further configured to move the specific area to a predetermined position on the touch screen.

9. The mobile terminal of claim 1, wherein the controller is further configured to display an indicator to visually indicate a process of adjusting the magnification rate of the text information on the touch screen, while adjusting the magnification rate of the text information included in the selected specific area.

10. The mobile terminal of claim 1, wherein the plurality of designated areas includes a list of areas or a calendar of areas.

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

designating, via a controller of the mobile terminal, a plurality of areas on the touch screen, each area including text information;

receiving, via a touch screen of the mobile terminal, a multi touch action;

selecting, via the controller, a specific area from the plurality of designated areas regardless of areas touched in the multi touch action;

determining, via the controller, at least one touch in the multi touch action is moving; and

adjusting, via the controller, a magnification rate of the text information included in the selected specific area in correspondence with the at least one touch moving.

12. The method of claim 11, further comprising:

determining at least one of the touches in the multi touch action is released; and

applying the magnification rate that was adjusted before the at least one of the multi touches was released to all of the plurality of designated areas.

13. The method of claim 11, further comprising:

determining at least one of the touches in the multi touch action is released; and

applying the magnification rate that was adjusted before the at least one of the multi touches was released only to the selected specific area.

14. The method of claim 11, further comprising:

determining at least one of the touches in the multi touch action is released; and

applying the magnification rate that was adjusted before the at least one of the multi touches was released to information displayed on the touch screen other than the plurality of areas.

15. The method of claim 11, further comprising:

fixing the magnification rate of text information included in an area other than the specific area, while adjusting the magnification rate of text information included in the specific area in response to the at least one touch moving.

16. The method of claim 11, further comprising:

selecting a specific area that matches a predetermined reference from among a plurality of different references that exclude the areas touched in the multi touch action.

17. The method of claim 11, further comprising:

dimming an area other than the specific area, while adjusting the magnification rate of the text information included in the selected specific area.

18. The method of claim 11, wherein after selecting the specific area, the method further comprises moving the specific area to a predetermined position on the touch screen.

19. The method of claim 11, further comprising:

displaying an indicator to visually indicate a process of adjusting the magnification rate of the text information on the touch screen, while adjusting the magnification rate of the text information included in the selected specific area.

20. The method of claim 11, wherein the plurality of designated areas includes a list of areas or a calendar of areas.
