Abstract

Disclosed is a character input method, by which it is possible to input a character through one touch-and-drag action. The method includes displaying a predetermined character at a location of a cursor on a display area when a predetermined character is selected in a selection area, displaying a next selection area when the predetermined character has been input for at least a predetermined time, and moving the cursor to a next space and waiting for an input of a next character in the display area when a dragging to the next selection area is performed when the predetermined character has been input for at least the predetermined time.

Claims

1. A method for inputting a character in a portable terminal, the method comprising the steps of:

displaying a predetermined character at a location of a cursor on a display area of a display unit of the portable terminal, when the predetermined character is selected in a selection area;

displaying a next selection area on the display area of the portable terminal, when the predetermined character has been input for at least a predetermined time; and

moving the cursor to a next space and waiting for an input of a next character in the display area, when a dragging to the next selection area is performed when the predetermined character has been input for at least the predetermined time.

2. The method as claimed in claim 1, further comprising displaying the selection area, which includes selectable characters, and the display area, which displays a character selected from the selection area, on the display unit, when a character input mode is selected.

3. The method as claimed in claim 1, further comprising moving the cursor to a previous space and locating the cursor at a location of the predetermined character on the display area, when a dragging to a previous selection area is performed after the dragging to the next selection area has been performed.

4. The method as claimed in claim 3, wherein the next selection area is deleted from the display unit when the dragging to the previous selection area is performed.

5. The method as claimed in claim 1, further comprising the steps of

displaying a corresponding selection area in which a corresponding character has been selected, when the cursor moves and is located at a location of the corresponding character during the display of the characters in the display area;

and

changing the corresponding character located at the location of the cursor in the display area to another character and displaying the changed another character, when the another character is selected in the corresponding selection area.

6. The method as claimed in claim 5, wherein the corresponding character is displayed in a manner that discriminates the corresponding character from other characters in the corresponding selection area.

7. The method as claimed in claim 1, wherein the step of displaying the next selection area comprises the steps of:

determining whether the selection area is located on a last location area among multiple vertical location areas for displaying multiple selection areas on the display unit, when the predetermined character has been input during at least the predetermined time; and

displaying the selection area on a predetermined location area, except for a first location area among the multiple vertical location areas, when the selection area is located on the last location area, and displaying the next selection area on a next location area that is next to the location area in which the selection area is located.

8. The method as claimed in claim 7, wherein the predetermined location area except for the first location area corresponds to a second location area among the multiple vertical location areas.

9. The method as claimed in claim 1, wherein when the selection area includes vertically arranged characters, the method comprises the steps of:

displaying the predetermined character at a location of the cursor on the display area when the predetermined character is selected in the selection area;

displaying the next selection area on a right side of the selection area when the predetermined character has been input during at least the predetermined time;

moving the cursor to a next space and waiting for an input of a next character on the display area when a right dragging to the next selection is performed in a state in which the predetermined character has been input during at least the predetermined time; and

moving the cursor to a previous space and locating the cursor at the location of the predetermined character on the display area when a left dragging to the selection area is performed after the dragging to the next selection area has been performed.

10. The method as claimed in claim 9, wherein the predetermined character is selected through a touch input or an upward and downward drag in a state in which the predetermined character has been input on the selection area.

11. The method as claimed in claim 1, wherein when the selection area includes horizontally arranged characters, the method comprises the steps of:

displaying the predetermined character at a location of a cursor on the display area when the predetermined character is selected in the selection area;

displaying the next selection area on a lower side of the selection area when the predetermined character has been input during at least the predetermined time;

moving the cursor to a next space and waiting for an input of a next character on the display area, when a downward dragging to the next selection is performed in a state in which the predetermined character has been input during at least the predetermined time; and

moving the cursor to a previous space and locating the cursor at the location of the predetermined character on the display area when an upward dragging to the selection area is performed after the dragging to the next selection area has been performed.

12. The method as claimed in claim 11, wherein the predetermined character is selected through a touch input or a left and right drag in a state in which the predetermined character has been input on the selection area.
