Description

Character input device of mobile terminal and its input method {INPUT DEVICE OF CHARACTER FOR MOBILEPHONE AND THE METHOD THEREOF}

The present invention relates to a character input device of a mobile terminal and an input method thereof, and more particularly to a character input device and a method of inputting a mobile terminal which can input English characters more conveniently by applying a navigation key or a joystick type direction key to a mobile phone. It is about.

In general, a mobile communication system sends a call message containing a unique number of a mobile terminal called through a call channel of a base station to call a mobile terminal, and then receives a response from the specified mobile terminal. It is a system to make a call.

In addition, as the mobile terminal adopts a digital method, data communication is enabled, and such data communication is used to provide various services such as an English text service.

Accordingly, the mobile terminal user can perform various operations such as storing English information in the mobile terminal or transmitting an English document by e-mail.

In order to input the characters required for data communication, mobile terminals are given letters that are assigned to each keypad in addition to numbers to keypads for entering numbers, as in conventional telephones. Characters, etc., the user can express almost anything you want.

The character input keyboard of the mobile terminal has been developed a lot. In general, the structure consists of 12 buttons with the proper combination of numbers and letters. The keypad has a certain shape all the time, and varies in manufacturing companies in character input methods, and requires additional learning for character input required by a consumer.

1 is a view showing a character input device on a keypad of a mobile terminal according to the prior art. As shown in the drawing, the mobile terminal according to the related art is divided into the display 110 and the keypad 120.

The English characters displayed on the keypad 120 of the mobile terminal are relatively easy to input compared to Korean characters because they do not consist of consonants and vowels differently from Korean characters.

The keypad of the mobile terminal includes two to three corresponding buttons of each number button (0 to 9) and English alphabets corresponding to the corresponding buttons of the numeric buttons (0 to 9) in order to input English characters.

That is, QZ is set to 1, ABC is set to 3, DEF is set to 4, GHI is set to 5, JKL is set to 6, MNO is set to 6, PRS is set to 7, TUV is set to 8, and WXY is set to 9.

Therefore, when the user of the mobile terminal inputs English characters, after finding the key position on the keypad of the English characters to enter in the character input mode (for example, the 'edit' mode of 'convenient function') of the terminal Select and enter a number key (0 to 9) several times according to the arrangement order.

In the conventional character input method using the keypad in which English letters are written together, the numbers are inputted by dialing the buttons in which the numbers are written in the same way as the number input button of the telephone when the numbers are first inputted. .

In case of inputting letters, the function assigned to the button is displayed by pressing the same number button several times in succession after switching from call mode to text input mode by operating a separate function button. Depending on whether you have operated the number of times, the English characters written on the corresponding button are sequentially changed and input.

For example, if a user enters "BOY", each letter "B", "O", "Y" in order to enter. First, when the numeric key 2 is pressed twice, "B" is displayed on the display.

Then, "O" is entered three times by pressing the numeric key 6, "Y" is entered by pressing the numeric key 9 three times, "BOY" is completed and displayed.

The conventional English character input method may be somewhat different depending on the arrangement of the keyboard according to the terminal manufacturer, but according to the English letter arrangement of the keypad, the English letters to be input are found on the number plate according to the alphabetical order. 9) was selected and entered.

Therefore, there is no big problem in inputting a simple name or giving, etc., but in order to write a relatively long English sentence such as sending an e-mail, a very large number of keys have to be manipulated. Therefore, there is a strong demand for a technology for inputting alphabetic characters more conveniently from the user's point of view.
