Embodiment Construction

[0038] discussed below Figure 1 to Figure 22 C and the various examples used to describe the principles of the disclosure in this patent document are for illustrative purposes only and should not be construed in any way as limiting the scope of the disclosure. Those skilled in the art will understand that the principles of the present disclosure may be implemented in any suitably arranged touch screen device.

[0039] The invention proposes a character input device and method. Therefore, according to the present invention, in a terminal having a touch screen, a plurality of character groups each including at least two characters are assigned to and displayed on at least two key areas generated by dividing the touch screen. When a press event occurs in a key area, characters included in the key area where the press event occurred are displayed enlarged. In addition, it is determined whether one of a release event and a drag event occurs in a key area in which characters are ...

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.

Description

technical field [0001] The present invention relates to a terminal with a touch screen, and more particularly, to a character input device and method. Background technique [0002] Traditional terminals output a QWERTY keyboard or a keypad in a touch screen instead of setting a keypad, so as to allow users to input characters conveniently. Examples of the terminal include electronic notes, mobile communication terminals, and personal digital assistants (PDAs). [0003] With the recent trend of miniaturization of terminals, the size of the touch screen is also reduced. In this case, it is difficult for the terminal to output the entire keyboard on the touch screen. Furthermore, even if the entire keyboard is output in a reduced form in the touch screen, the user may have difficulty in accurately inputting desired characters due to the small keypad. In other words, the user may mistakenly press a button located adjacent to a desired button, and thus have to perform an input...
