Abstract

A method and apparatus for controlling a cursor in a portable terminal is provided. The method includes displaying a character on a screen, modifying the character and displaying the modified character, when a position of a cursor is designated, and restoring the modified character, when the designation of the position of the cursor is cancelled.

Claims

1. A method of controlling a position of a cursor in a portable terminal, the method comprising:

displaying a plurality of characters on a display screen in response to a plurality of touch inputs on a input screen;

detecting an input for moving a cursor;

moving the cursor between two of the plurality of characters, in response to the input;

modifying at least two characters designated based on a position of the cursor displayed on the display screen; and

restoring the modified at least two characters, when the designation of the at least two characters is cancelled,

wherein modifying the designated at least two characters comprises enlarging a space between the designated at least two characters,

wherein modifying the at least two characters comprises;

changing a size of the space between characters at the position of the cursor and in a predetermined adjacent area in an upward, downward, left, and right direction from the position of the cursor, for display; and

sensing an area select request event for selecting an area for enlarging the space between the designated at least two characters, and

wherein, when the area select request event is sensed, the cursor is formed to include a first handler and a second handler, and the area is selected by moving the first handler and the second handler.

2. The method of claim 1, wherein modifying the at least two characters further comprises:

moving the cursor to a designated position, when the position of the cursor is designated.

3. The method of claim 2, wherein modifying the at least two characters further comprises:

detecting an input event corresponding to the position of the cursor, when movement of the cursor stops.

4. The method of claim 3, wherein the input event is at least one event of inserting a character, deleting a character, inputting an indent, inputting a line feed, and converting a Hangul character into a Chinese character.

5. The method of claim 2, wherein moving the cursor comprises:

moving the cursor when at least one of a touch event, a tap event, a flick event, a pen-touch event, a double-touch event, and a double-tap event is detected.

6. The method of claim 1, wherein restoring the modified at least two characters comprises restoring the space between the characters, which have been enlarged.

7. The method of claim 1, wherein the area select request event corresponds to at least one of a drag event, a swipe event, a drag-and-drop event, a pinch zoom event, and a hovering event.

8. The method of claim 1, wherein displaying the plurality of characters on the display screen comprises:

displaying the input screen in which the plurality of characters are input or the display screen that displays the plurality of characters.

9. The method of claim 1, wherein restoring the modified at least two characters comprises:

restoring a size of the space between the designated at least two characters to an original size, when movement of the cursor is not sensed during a predetermined period of time or a cursor movement termination event is sensed.

10. The method of claim 9, wherein the cursor movement termination event is at least one of a touch event, a tap event, a flick event, a pen-touch event, a double-touch event, and a double-tap event provided at an end of displayed characters.

11. An apparatus for controlling a position of a cursor in a portable terminal, the apparatus comprising:

a display panel configured to display a plurality of characters and a cursor;

a touch panel; and

a controller configured to;

cause the display panel to display the plurality of characters on a display screen in response to a plurality of touch inputs on an input screen;

detect an input for moving a cursor using the touch panel;

move the cursor between at least two of the plurality of characters, in response to the input;

modify the at least two characters designated based on a position of the cursor displayed on the display screen; and

restore the modified at least two characters, when the designation of the at least two characters is cancelled,

wherein the controller is further configured to modify the at least two characters designated based on the position of the cursor displayed on the display screen by enlarging a space between the designated at least two characters,

wherein the controller is further configured to move the cursor to a designated position, when the designation of the position of the cursor is sensed, and control a size of the space between the at least two characters at the position of the cursor and in a predetermined adjacent area in an upward, downward, left, and right direction from the position of the cursor, and

wherein the controller is further configured to select an area by moving a first handler and a second handler, which form the cursor, when an area select request event is detected, and process the selected area.

12. The apparatus of claim 11, wherein the controller is further configured to detect an input event at a position to which the cursor is moved, wherein the input event is at least one of inserting a character, deleting a character, inputting an indent, inputting a line feed, and converting a Hangul character into a Chinese character.

13. The apparatus of claim 11, wherein the controller is further configured to select the area by using at least one of a drag event, a swipe event, a drag-and-drop event, a pinch zoom event, and a hovering event.

14. The apparatus of claim 11, wherein the controller is further configured to sense a movement of the cursor, and to move the cursor when at least one of a touch event, a tap event, a flick event, a pen-touch event, a double-touch event, and a double-tap event is sensed.

15. The apparatus of claim 11, wherein the controller is further configured to restore the size of the space between the at least two characters to an original size, when movement of the cursor is not sensed during a predetermined period of time or a cursor movement termination event is sensed.

16. The apparatus of claim 15, wherein the cursor movement termination event is at least one of a touch event, a tap event, a flick event, a pen-touch event, a double-touch event, and a double-tap event provided at an end of displayed characters.
