Character input apparatus and method for automatically switching input mode in terminal having touch screen
First Claim
1. A character input method for automatically switching an input mode 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 acquired 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 a first of the key regions, determining whether a drag event occurs prior to occurrence of a release event;
executing one of a separate input mode for inputting one of characters of a corresponding character group and a text input mode for inputting a word including one of the characters of the character group according to whether the drag event occurs; and
upon execution of the separate input mode, assigning each character of the character group associated with the first key region to a different one of the key regions other than the first key region and displaying the characters of the character group in the other key regions.

Abstract
Provided is a character input method and apparatus for automatically switching an input mode in a terminal having a touch screen. If a press event occurs in one of key regions displayed in the touch screen, it is determined whether a drag event occurs prior to occurrence of a release event. According to whether the drag event occurs, one of a separate input mode for inputting one of characters of a corresponding character group and a text input mode for inputting a word including one of the characters of the character group is executed. Thus, a user can easily input a character by rapidly selecting a desired input mode.

9. A character input method for automatically switching an input mode in a terminal having a touch screen, the character input method comprising:
-
in a text input mode for inputting a word including one of characters from character groups, each of which includes at least two characters, assigning the character groups to at least two key regions acquired 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 a first of the key regions, counting time from a point of time at which the press event occurs; if the counted time exceeds a previously stored threshold value, switching to a separate input mode for inputting one of characters from a corresponding character group; upon execution of the separate input mode, assigning each character of the character group associated with the first key region to a different one of the key regions other than the first key region key region and displaying the characters of the character group in the other key regions; determining whether a release event occurs in one of the other key regions assigned to the each character; and outputting a character in the key region where the release event occurs onto a predetermined input editor window of the touch screen. - View Dependent Claims (10)

11. A character input method for automatically switching an input mode 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 acquired 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, determining whether a drag event occurs prior to occurrence of a release event; if it is determined that the drag eve occurs, switching to a separate input mode for inputting one of characters of a corresponding character group; upon execution of the separate input mode, checking a distance and a direction of the drag event; displaying a character corresponding to the checked distance and direction of the drag event from among characters of the key region where the press event occurs; and if the release event occurs when the character is displayed, outputting the displayed character. - View Dependent Claims (12, 13, 14, 15)

16. A character input apparatus for automatically switching an input mode in a terminal having a touch screen, the character input apparatus comprising:
-
a memory configured to store character groups, each of which includes at least two characters, displayed in at least two key regions acquired by dividing a region of the touch screen based on one-to-one correspondence; a touch screen configured to display the character groups in the key regions based on one-to-one correspondence and generating a press event, a release event, and a drag event according to user input to each of the key regions; and a controller configured to; determine whether the drag event occurs prior to occurrence of the release event if the press event occurs in a first of the key regions of the touch screen; execute one of a separate input mode for inputting one of characters of a corresponding character group and a text input mode for inputting a word including one of the characters of the character group according to whether the drag event occurs; and upon execution of the separate input mode, assign each character of the character group associated with the first key region to a different one of the key regions other than the first key region and display the characters of the character group in the other key regions. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24)
