Description

Character input device and method in a device using a touch screen {APPARATUS AND METHOD FOR INPUTTING LETTERS IN DEVICE WITH TOUCH SCREEN}

The present invention relates to a character input device and method in a device using a touch screen, and in particular, in the device using a touch screen, the phoneme is placed in the center and up, down, left and right of each key button on the 2x6 virtual keyboard The present invention relates to an apparatus and a method for inputting all phonemes by one drag.

In general, a touch screen provides an interface for a user to input a command or information to a terminal by touching an icon displayed on the screen using a finger or a pointing device. Here, the touch screen is a kind of input device, and has recently been applied to various terminals such as a mobile phone, a smart phone, an unmanned cash dispenser, a Palm PC, and a personal digital assistant (PDA).

Character input through the touch screen is largely divided into a handwriting input method and a soft keyboard input method. In the handwriting input method, a character is input by writing a letter with a stylus pen on a screen as if writing a pen on a paper. In the soft keyboard input method, a small keyboard having a user interface in the form of a general keyboard is displayed on a screen to input characters by a pen click.

Frequently, a typo may occur when a recognition rate for a handwritten text written on a screen is reduced in a device that receives a text by the handwriting input method. In this case, the user must clear the typo and write the required cursive again. Therefore, the handwriting input method has a problem of low input speed and accuracy. In the above soft keyboard input method, each key button can be used as small as 4x4mm to display all the keys on the keyboard on the PDA screen, so that characters can be input only by using an auxiliary tool such as a stylus pen. In addition, there is a problem that is likely to be incorrectly input even when using such an aid. In particular, when the user is in a moving bus or walking, a lot of input errors occur.

In order to compensate for these problems, various types of soft keyboards have been recently developed in which characters can be input by only a finger without an aid. The common feature of these soft keyboards is that they place letters (ie, consonants and vowels) so that users can easily input Korean or English using only their fingers. Is to maximize the size of the button. Therefore, when inputting a character using the soft keyboards as described above, there is a problem that the user must press a key button several times even if one consonant or a vowel is input. In particular, this problem is more highlighted when inputting a vowel consonant or a vowel vowel.

A common problem with these prior arts is that in addition to the inconvenience of typing, the layout of the keyboard is uniquely defined for each software so that each time the user changes the keyboard, it takes time to get used to the layout of the keyboard. In some cases, the layout of a given keyboard is often inconvenient to type.

An object of the present invention is to provide a character input device and method in a device using a touch screen.

Another object of the present invention is to provide an apparatus and method for minimizing a character input time using a finger and increasing usability when inputting characters in a device using a touch screen.

It is another object of the present invention to provide an apparatus and method for arranging phonemes at the center, top, bottom, left and right of each key button on a 2x6 virtual keyboard in a device using a touch screen, and inputting all the phonemes with a single drag. .

It characterized in that it comprises an input unit.

According to the present invention, by placing a phoneme on the center, top, bottom, left, and right sides of each key button on a 2x6 virtual keyboard in a device using a touch screen and inputting all phonemes with a single drag, input of all letters by only three times or less is input. This has a possible advantage. In addition, the present invention has the advantage that by minimizing the number of key buttons, the size of the key button can be made large enough, even if a virtual keyboard is made to fit the standard keyboard size, enough characters can be input with only a finger without typos. In addition, depending on the type of soft keyboard, a virtual keyboard size that is larger than a standard keyboard is often introduced. In this case, the screen may be hidden depending on the application. However, when the virtual keyboard size of 2x6 low height is introduced as in the present invention, it is possible to prevent the screen from being covered.
