Description

A method for controlling a mobile telephone to be capable of inputting character easily}

The present invention relates to a control method of a mobile phone, and more particularly, to a control method of a mobile phone that is easy to input characters that can input Korean and special characters including English more quickly and conveniently.

As mobile communication becomes popular, various additional services are provided, one of which is a text transmission service. That is, as the interest in the text transmission service for transmitting the text input to the mobile phone of the other party to the mobile phone has been concentrated, the interest in the text input method is also increasing.

Early mobile phones were able to input only English as shown in FIG. In other words, after switching the operation mode of the mobile phone to the character input mode, when the dial buttons are continuously pressed, the character string set in the corresponding dial button is circulated and appears on the display unit (LCD). When the desired character is displayed on the display, the setting key (*, #) is pressed or when a certain time elapses, the character displayed on the display is input.

For example, if you press the dial 3 button once, the first letter D appears on the display, and if you press the dial 3 button twice in succession, E appears on the display. In other words, press and hold the 3 dial button to display D, E, F, D, E,…. As shown in the display, the character string is circulated and the setting character (*, #) is pressed while the desired character is displayed on the display. Moves. As such, early mobile phones could only enter 26 English alphabets.

As a method of inputting Hangul into a mobile phone, Dr. Jong-Rak Lee of the Korea Telecom Research & Development Group developed in 1992 and established as a national standard (standard number: KCS 44) "Adjacent Touch-Tone Assembly (ATTACH). Code for Hangul) ".

FIG. 6 is a diagram illustrating arrangement of consonants and vowels of Korean characters according to ATTACH codes. The ATTACH code is a method of inputting Korean characters using a relationship between adjacent dial buttons. For example, if the first dial button is pressed first and the neighboring second dial button is pressed, "a" is entered. On the contrary, if the second dial button is pressed, the neighboring first dial button is pressed, "b" is entered. If you type "ㄷ", press dial button 1 first and then press dial button 5 placed diagonally.

That is, Korean consonants and vowels are input using two adjacent dial buttons. In this way, ATTACH code can input 108 characters including Korean as well as special characters. In FIG. 6, only Korean consonants and vowels are represented, but special characters such as an English alphabet, an exclamation mark, and a question mark are also displayed between the buttons for input of English and special characters.

In the method of inputting Korean, there is also a method applying the English input method illustrated in FIG. 5. This method is the most commonly used Hangul input method used in the mobile phone, as shown in Figure 7 after pressing the dial button continuously after switching the mobile phone to the Hangul input mode, the string set on the dial button is circulated Appears on the display. When the desired character is displayed on the display, the setting key (*, #) is pressed or when a certain time elapses, the character displayed on the display is input.

For example, if you press the 3rd dial button once, the first Korean consonant "한글" appears on the display, and if you press the 3rd dial button twice in a row, "ㅅ" appears on the display. That is, if you keep pressing the dial button 3, ㅂ, ㅅ, ㅇ, ㅂ, ㅅ…. As shown in the display, the character string is circulated, and when the desired consonant appears on the display, the dial button repeatedly describes the vowel to be combined with the consonant. When the button is pressed in this way, the display unit repeatedly shows the shape of the Hangul that combines the selected consonant and the vowel corresponding to the dial button being pressed.

In other words, press the dial button 4 once to enter the letter "previous" and press the dial button 6 repeatedly so that "za", "ja" and "low" appear repeatedly on the display. When the "low" character is shown on the display, when the dial button 1 is pressed twice, "red" appears first on the display and then "front" appears on the display.

In this way, when the desired letter is displayed on the display, pressing the set key (*, #) or when a certain time elapses, the letter shown on the display is input and the cursor moves to receive the next letter. The English input method is the same as the Korean input method, but the English input mode is required only when the operation mode of the mobile phone is changed to the English input mode.

However, in the case of inputting characters into the mobile phone using the ATTACH code described above, as a plurality of characters are displayed between the buttons, the surroundings of the buttons are densely packed with printed characters, which is not only aesthetically pleasing but also easy to identify. It is difficult to write letters in size. In addition, in order to downsize the mobile phone, there is a problem in that a large amount of space cannot be allocated between the button and the button.

In addition, in case of inputting letters by pressing dial button continuously, the alphabet of English and Korean corresponding to the button should be marked on the button. That is, as "D, D, W" is displayed along with "A, B, C" on the 2nd dial button, the size of the displayed letter becomes small and it is difficult to identify. In addition, in the case of adding a special character in addition to Hangul, the severity of the problem is intensified, and in addition, it is necessary to repeatedly press the dial button in order to input a character.

Accordingly, the present invention has been made to solve the above problems, and an object of the present invention is to provide a method for controlling a mobile phone that is easy to input characters that can be entered more quickly and conveniently, including English and special characters. .

In order to achieve the above object, the present invention provides a control method of a mobile phone: when the text input mode is set, the display unit of the mobile phone is divided into a text input window indicating a character input by a user and an index window indicating an inputable character string. And a second step of displaying a character corresponding to the dial button on a character input window when the dial button corresponding to the character displayed on the index window is pressed, and a dial corresponding to the character switching function displayed on the index window. Press the button to switch the text displayed in the index window to Korean, English or special characters; and press the function button corresponding to the storage function displayed in the index window, and the text displayed in the text input window is stored in the memory. And a fourth step of terminating the character input mode.
