Abstract

A portable terminal with a touch screen and a method for displaying tags on the touch screen of the portable terminal are disclosed. The method includes: calculating a distance between the first and second touch points detected on the touch screen; identifying the number of tags that will be displayed, according to the calculated distance; and displaying at least one of the identified number of tags.

Claims

1. A method for displaying tags on a touch screen of a portable terminal, comprising:

calculating, if first and second touches are detected on the touch screen, a distance between the first and second touch points;

identifying a number of tags that will be displayed, according to the calculated distance; and

displaying at least one of the identified number of tags.

2. The method of claim 1, wherein displaying at least one of the identified number of tags further comprises:

changing the number of the tags according to the changes in the calculated distance and displaying at least one of the changed number of tags.

3. The method of claim 2, wherein displaying at least one of the identified number of tags further comprises:

determining whether a drag is detected;

identifying, if a drag is detected, the movement direction and distance of the detected drag, the drag having a moving coordination during a time period; and

removing at least one tag from the displayed tags; and

adding a number of new tags on the display unit according to a number of removed at least one tag in the movement direction.

4. The method of claim 2, wherein displaying at least one of the identified number of tags includes one of:

arranging tags in an arc shape or in a straight line.

5. The method of claim 1, wherein the tag is a tag menu or identification data.

6. A portable terminal comprising:

a touch screen including a display unit for displaying tags and at least one touch sensor for detecting touches on the touch screen; and

a controller in communication with the touch screen for;

calculating a distance between first and second touch points that are detected on the touch screen,

identifying the number of tags that will be displayed, according to the calculated distance, and

displaying at least one of the identified number of tags on the display unit.

7. The portable terminal of claim 6, wherein, if the calculated distance is changed, the controller changes the number of tags according to the changed distance and displays at least one of the changed number of tags on the display unit.

8. The portable terminal of claim 6, wherein, if a drag is detected, the controller identifies:

the movement direction and distance of the detected drag, the drag having a moving coordination during the time period,

removes at least one tag from the displayed tags; and

adds a number of new tags on the display unit according to a number of removed at least one tag in the movement direction.

9. The portable terminal of claim 7, wherein the controller arranges tags in one of:

an arc shape or in a straight line.

10. The portable terminal of claim 6, wherein the tag is a tag menu or identification data.

11. A portable terminal including:

a touchscreen input device comprising a plurality of pixels;

a controller comprising;

a processor in communication with a memory, the memory including code, which when accessed by the processor causes the processor to execute the steps of;

receiving signals from the touchscreen, the signals associated with selected ones of the pixels;

determining a first touch and a second touch of the touchscreen;

determining a distance between the first and second touches;

determining a number of tags to be displayed based on the distance, wherein the number of tags is predetermined for each of a plurality of distances;

determining an order of displaying the number of tags; and

displaying the determined number of tags in the determined order.

12. The portable terminal of claim 11, the processor further executing code for:

determining a change in distance between the first and second touches; and

determining a number of tags to be displayed based on the changed distance.

13. The portable terminal of claim 11, wherein the order is determined based on the frequency of selection of the tags.

14. The portable terminal of claim 11, wherein the tags are displayed in one of:

an arc and a straight line.
