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;

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

receive a multi touch action at multiple touch points on the touch screen,

select a specific area from the plurality of provided areas according to a predetermined reference, wherein the specific area is selected regardless of a location of areas touched in the multi touch action,

display the selected specific area in a form of a popup window at a predetermined position on the touch screen,

determine at least one touch in the multi touch action is moving away from at least one of the multiple touch points after the popup window is displayed at the predetermined position,

adjust a magnification rate of the text information included in the popup window in correspondence with the at least one touch moving,

dim the plurality of areas other than the popup window, while adjusting the magnification rate of the text information included in the popup window, and

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 popup window,

wherein the indicator includes a set of letters, different in size according to the process,

wherein each of the letters included in the set of letters indicates a magnification rate currently applied to the text information included in the popup window in correspondence with the at least one touch moving,

wherein the indicator is separately displayed from the text information,

wherein a letter having a size corresponding to the currently applied magnification rate is visually emphasized, and

wherein the controller is further configured to determine that at least one of the touches in the multi touch action is released, and to apply the magnification rate that was last adjusted before the at least one of the touches in the multi touch action was released to all of the plurality of provided areas or to just the popup window.

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

3. 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 popup window, while adjusting the magnification rate of text information included in the popup window in response to the at least one touch moving.

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

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

6. The mobile terminal of claim 1, wherein the text information is contact information.

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

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

receiving, via the touch screen, a multi touch action at multiple touch points on the touch screen;

selecting, via the controller, a specific area from the plurality of provided areas according to a predetermined reference, wherein the specific area is selected regardless of a location of areas touched in the multi touch action;

displaying the selected specific area in a form of a popup window at a predetermined position on the touch screen;

determining, via the controller, at least one touch in the multi touch action is moving away from at least one of the multiple touch points after the popup window is displayed at the predetermined position;

adjusting, via the controller, a magnification rate of the text information included in the popup window in correspondence with the at least one touch moving;

dimming the plurality of areas other than the popup window, while adjusting the magnification rate of the text information included in the popup window;

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 popup window,

wherein the indicator includes a set of letters, different in size according to the process,

wherein each of the letters included in the set of letters indicates a magnification rate currently applied to the text information included in the popup window in correspondence with the at least one touch moving,

wherein the indicator is separately displayed from the text information, and

wherein a letter having a size corresponding to the currently applied magnification rate is visually emphasized,

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

applying the magnification rate that was last adjusted before the at least one of the touches in the multi touch action was released to all of the plurality of provided areas or to just the popup window.

8. The method of claim 7, further comprising:

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

9. The method of claim 7, further comprising:

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

10. The method of claim 7, further comprising:

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

11. The method of claim 7, wherein the plurality of provided areas includes a list of areas or a calendar of areas.

12. The method of claim 7, wherein the text information is contact information.
