Character input apparatus and method
First Claim
1. A character input method in a terminal having a touch screen, the character input method comprising:
- assigning character groups, each of which includes at least two characters, to at least two key regions generated by dividing a region of the touch screen and displaying the character groups in the corresponding key regions, based on one-to-one correspondence;
if a press event occurs in one of the key regions, enlarging and displaying characters included in the key region where the press event occurs;
determining whether one of a release event and a drag event occurs in one of the key regions where the characters are displayed enlarged;
if it is determined that the drag event occurs, indicating the key region where the drag event occurs according to distance and direction of the drag event; and
if the release event occurs in the indicated key region, outputting characters included in the indicated key region on the touch screen.

Abstract
Provided is a character input method and apparatus. The character input method includes assigning character groups, each of which includes at least two characters, to at least two key regions generated by dividing a region of the touch screen and displaying the character groups in the corresponding key regions, based on one-to-one correspondence, if a press event occurs in one of the key regions, enlarging and displaying characters included in the key region where the press event occurs, determining whether one of a release event and a drag event occurs in one of the key regions where the characters are displayed enlarged, if it is determined that the drag event occurs, indicating the key region where the drag event occurs according to distance and direction of the drag event, and if the release event occurs in the indicated key region, outputting characters included in the indicated key region on the touch screen. Thus, a user can easily find a desired character and accurately input the character, thereby performing key input more conveniently and quickly.

12. A character input method in a terminal having a touch screen, the character input method comprising:
-
assigning character groups, each of which includes at least two characters, to at least two first key regions generated by dividing a region of the touch screen and displaying the character groups in the corresponding first key regions, based on one-to-one correspondence; if a press event occurs in one of the first key regions, enlarging and displaying characters included in the first key region where the press event occurs in second key regions; determining whether a release event occurs in the first key region if the press event occurs in one of the second key regions in a state where the press event occurs in the first key region; if it is determined that the release event occurs in the first key region, determining whether the release event occurs in the second key region where the press event occurs; and if it is determined that the release event occurs in the second key region, outputting a character included in the second key region onto the touch screen. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)

24. A character input apparatus in a terminal having a touch screen, the character input apparatus comprising:
-
a memory for storing character groups, each of which includes at least two characters displayed in each of at least two key regions generated by dividing a region of the touch screen; a touch screen for displaying the character group in each of the key regions and generating a press event, a release event, and a drag event according to user'"'"'s input to the key regions; and a controller for assigning the character groups to the key regions and displaying the character groups in the corresponding key regions based on one-to-one correspondence, if a press event occurs in one of the key regions, enlarging and displaying characters included in the key region where the press event occurs, determining whether one of the release event and the drag event occurs in one of the key regions where the characters are displayed enlarged, indicating the key region where the drag event occurs according to distance and direction of the drag event if the drag event occurs, and outputting characters included in the indicated key region on the touch screen if the release event occurs in the indicated key region. - View Dependent Claims (25, 26, 27)
