Abstract

A character input method and apparatus in an electronic terminal are provided. The character input method includes displaying a virtual keypad having at least one key area to which a plurality of characters are associated, displaying a plurality of areas when a touch is detected on the at least one key area, detecting whether the touch includes a drag and inputting, after the drag is detected, a character mapped to an area corresponding to a point where the drag is released.

Claims

1. A method of character input, the method comprising:

displaying a virtual keypad that includes a display of at least one character;

receiving a touch input on the at least one character;

displaying, in response to the touch input on the at least one character, one or more regions corresponding to one or more characters, with the one or more regions provided in a position other than a position of the display of the at least one character;

detecting a drag input in conjunction with the touch input; and

inputting a character corresponding to a region where the drag input is released,

wherein the region is among the displayed one or more regions corresponding to the one or more characters.

2. The method of claim 1, further comprising changing, by selecting a predefined key, a language of character display.

3. The method of claim 1, further comprising outputting an audio signal indicating then touch input on the at least one character.

4. The method of claim 1, further comprising providing a window displaying each inputted character.

5. The method of claim 4, wherein the window is provided above the virtual keypad.

6. The method of claim 1, wherein different characters are displayed on one or more respective regions.

7. The method of claim 1, wherein a total number of displayed characters varies based on whether the selected at least one character is positioned at one of a top row, a bottom row, and a side column of the virtual keypad.

8. The method of claim 1, wherein the one or more characters are displayed on respective sides of the selected at least one character, mapped to respective areas adjacent to the selected at least one character.

9. The method of claim 8, wherein a total number of the respective areas varies based on whether the selected at least one character is positioned at one of a top row, a bottom row, and a side column of the virtual keypad.

10. The method of claim 8, further comprising, after receiving the touch input on the at least one character, displaying lines separating each of the respective areas.

11. The method of claim 10, wherein the lines are not displayed after release of the drag.

12. A mobile terminal comprising:

a display configured to display a virtual keypad with at least one character; and

a controller configured to

receive a touch input on the at least one character,

display, in response to the touch input on the at least one character, one or more regions corresponding to one or more characters, with the one or more regions provided in a position other than a position of the display of the at least one character,

detect a drag input in conjunction with the touch input, and

receive an input of a character corresponding to a region where the drag input is released,

wherein the region is among the displayed one or more regions corresponding to the one or more characters.

13. A character input apparatus comprising:

a controller capable of controlling;

display of a virtual keypad with at least one character,

detection of a touch of the at least one character,

display, if the touch of the at least one character is detected, of one or more regions having one or more characters, wherein each of the one or more regions is displayed separate from each of the other one or more regions,

detection of a drag in conjunction with the touch, and

input of a character displayed on a region of the one or more regions that corresponds to release of the drag.

14. A device comprising:

a display for displaying a virtual keypad with at least one character,

wherein, upon selection of the at least one character, one or more different characters are displayed on one or more regions that are provided in positions other than a position of the display of the at least one character, and

wherein, if a drag associated with the selection is detected, a character is input from among the one or more different characters based on a region of the one or more regions corresponding to release of the drag.

15. A non-transitory computer-readable storage medium storing instructions that, when executed by one or more processors, cause the one or more processors to perform operations comprising:

identifying selection of at least one character of a displayed virtual keypad;

displaying, in response to the selection of the at least one character, one or more regions corresponding to one or more characters, with the one or more regions provided in positions other than a position of the display of the at least one character;

detecting a drag in conjunction with the selection of the at least one character; and

inputting a character corresponding to a region where the drag is released,

wherein the region is among the displayed one or more regions corresponding to the one or more characters.
