Description

Character input device and method through touch keyboard of terminal {APPARATUS AND METHOD FOR INPUTING CHARACTERS ON TOUCH KEYBOARD OF TERMINAL}

The present invention relates to an apparatus and a method for inputting a character of a terminal, and more particularly, to an apparatus and a method for inputting a character through a touch keyboard of a terminal.

A representative example of a personal terminal is a personal digital assistant (PDA).

Generally, PDA is equipped with various software and peripherals based on the central processing unit (CPU), memory, operating system (OS), and operating system that are the basis of the computer, and performs information collection, storage, creation, and retrieval functions. In recent years, the mobile phone module has been developed to enable a voice call and data communication (using the Internet).

In general, a PDA includes a touch screen, which is composed of a display such as an LCD (Liquid Crystal Display) and a touch panel installed thereon. A user executes an application by touching an icon displayed on a touch screen with a finger or a pointer, or touches a touch keyboard displayed on a predetermined area on a touch screen to input characters.

1 is a view showing a general keyboard arrangement of the touch keyboard arrangement method of the conventional terminal.

Referring to FIG. 1, a touch screen of a terminal includes a display unit which displays input characters on a screen, and a touch keyboard that receives characters. The touch keyboard may be referred to as a personal computer (hereinafter, referred to as a PC). Keyboard layout is applied.

FIG. 2 is a diagram illustrating another keyboard arrangement for inputting Hangul among touch keyboard arrangement schemes of a conventional terminal. Here, the known Naragle ^TM array is shown.

Referring to FIG. 2, a 5 * 3 array method or a 3 * 4 array method except for special keys is applied to a touch keyboard to input Korean consonants and vowels.

As described above, when the keyboard arrangement method and the naragle arrangement method of the PC are applied to the touch screen of the terminal, the size of the touch keyboard implemented in the touch screen is inevitably reduced due to the limited size of the touch screen. Therefore, in the case of the input method using the conventional touch screen, the size of each key of the touch keyboard implemented in the touch screen is reduced, which makes it difficult to see the characters and is inconvenient to touch. Degrades. In particular, in the case of Hangul input, a difficulty occurs in a pointing operation of moving a finger or a pointer from side to side to complete a desired character, and the speed due to the character input decreases as the movement for the pointing operation occurs.

FIG. 3 is a diagram illustrating another keyboard arrangement for inputting Hangul among touch keyboard arrangement schemes of a conventional terminal. Here, known Sasang Hangul ^TM arrangement is shown.

Referring to FIG. 3, the touch keyboard employs a 3 * 4 arrangement except for special keys to input Korean consonants and vowels.

When applying the Hangul Hangul arrangement method to the touch screen of the terminal as described above, the user can input a character with a minimum number of keys while minimizing an error, but in the case of consonants, two characters match one key It is inconvenient to press one key up to two times to input one consonant. To improve this, if we match all the consonants, one per key, the size of each key is reduced by increasing the number of keys needed from 12 to 19. Therefore, in the case of a typical arrangement using a touch screen of Sasang Hangul, the speed of character input is reduced. If the consonants are deformed and the consonants are released, the speed of character input decreases due to the increase of the number of keys.

Accordingly, there is a need for a method of inputting a character using a touch keyboard to facilitate character input on a touch screen of the terminal.

The present invention provides a character input device and method for inputting a character using a touch keyboard to facilitate character input on a touch screen of a terminal.
