The present invention relates to a text input method of a mobile communication terminal, and more particularly, to a mobile communication terminal having a text input function for shortening a text input time and a text input method thereof.

Recent mobile communication terminals are equipped with various additional functions in addition to simple telephone functions. For example, input functions such as SMS (Short Message Service), phone number, schedule, memo and other information are basically provided, and even chatting and web surfing are possible.

However, most of the additional functions are performed by inputting a character, and the character is input by using a keypad attached to the terminal. Therefore, a lot of researches are being made by terminal manufacturers to develop a method for easily inputting characters.

Conventional Korean input methods include Cheonjiin and ez (Korean) input method.

1 is an exemplary view showing a keyboard arrangement used in the conventional Cheonjiin method, Figure 2 is an exemplary view showing a keyboard arrangement used in the conventional easy (ez) Hangul input method.

Referring to FIG. 1, the Cheonjiin method is assigned to assign seven representative buttons to each of two representative consonants designated by the Cheonjiin method, and to use three buttons as function (ㅣ, ·, ㅡ) keys for vowel input. .

The Cheonjiin method with the keyboard layout as described above has the advantage of completing all the vowels with only three buttons. However, if one button is pressed several times, the user may make a mistake. There is a problem that an excessive force can be applied, and there is a problem that a relatively large number of buttons must be input in order to input a double vowel (eg, ㅔ, ㅖ, ㅐ, ㅒ, ㅝ, ㅞ, ㅚ, ㅙ, etc.).

Next, referring to FIG. 2, the ez Hangul input method allocates one representative consonant designated by the ez Hangul input method to each of six buttons, and assigns the ez to the three buttons. One or two representative vowels specified by the Korean input method are assigned and used.

Consonants and vowels not displayed on the buttons in the easy Hangul input method as described above are configured to be input using a stroke addition button or a double consonant button.

However, the EZ Korean input method is less frequently used to input one button many times than the Cheonjiin method, but there is a problem in that the buttons arranged far apart for character completion are input. Since a large amount of time is required for the movement of the finger, there is a problem in that the character input time is increased.

And, many of the first-time users are confused by the consonant input of ㅋ, ,, ㅌ, ㅂ, ,, ,, ㅎ, ㅎ which are not displayed on the keypad.

In addition, since the two character input methods are designed to input characters using one finger (for example, a thumb) in common, there is a problem that the finger is increased as the number of button inputs increases. .

Accordingly, the present invention has been created to solve the above-mentioned conventional problems, by sequentially assigning the characters displayed on the keypad keyboard so that the user can easily find the character position by the sequence, and thus the character input time. It is an object of the present invention to provide a mobile communication terminal and a method of inputting the text, which can shorten the time.

In addition, the present invention is to display both the terminal sound and the short vowels on the keypad of the mobile communication terminal to display the location of the consonants and vowels, including the voicing intuitively by looking at the keypad keyboard to facilitate character input and its An object of the present invention is to provide a character input method.

In addition, the present invention provides a mobile communication terminal and a character input method for allocating all the terminal sounds arranged on the keyboard to the left column and all the short vowels to the right column, so that one-hand input as well as two-hand input can be performed naturally. There is a purpose.

In addition, the present invention provides a mobile communication terminal and a method for inputting the characters to easily input the consonants through repeated input of the same key button without separately using a function key for inputting a character such as a stroke addition button or a consonant button The purpose is to provide.

In order to achieve the above object, the present invention provides a terminal sound of Hangul to each button of two rows (1 column, 2 columns) from the left side to the right side of the keypad keyboard and four rows (1 to 3 rows) from the upper side to the lower side. A key input unit which allocates two in sequence and displays the last two terminal tones of Hangul in the first column (column 1) button of four rows; A memory unit for storing the character data and a character input algorithm according to the type of the character; A controller for determining a character assigned to a button input through the key input unit; And a display configured to display the determined character under the control of the controller.

In addition, the mobile communication terminal of the present invention for achieving the above object is the first column (three columns) from the right side to the left side of the keypad keyboard and four buttons (1 to 4 rows) from the upper side to the lower side. Assign two short vowels in sequence, and display the last four short vowels in order in the first column (column 3) and the second column (column 2) buttons from right to left in the last row (row 4). It comprises a key input unit configured to.

In addition, the mobile communication terminal of the present invention for achieving the above object has three columns (1 to 3 columns) from the left side to the right side of the keypad, and four buttons (1 to 4 rows) from the upper side to the lower side. Assigns two alphabetic characters sequentially and displays the last six alphabetic characters in sequence in the second column (column 2) and the third column (column 3) buttons from left to right in the last row (row 4). It comprises a key input unit.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

However, it is obvious that the functional blocks may additionally perform other functions in the functional block of the same name according to the embodiment.

Meanwhile, although the key input unit 106 and the display unit 107 are generally configured to be separated, it is noted that the input function and the display function may be combined into one, such as a touch screen.

In the present invention, the memory unit 105 stores character data for each country and a character input algorithm according to the type of the character. Hereinafter, in the embodiment of the present invention, a character input algorithm using Korean and English characters will be described.

The controller 108 determines whether a key button for character input is input through the key input unit 106, and controls the display unit 107 to display the input character when the key button for character input is input.

The character input mode includes a mode for inputting Korean and a mode for inputting English, and enables input of Korean or English according to the mode selection. The text input mode is automatically switched according to an operation state of the terminal (eg, a phone call, a text message transmission, an e-mail transmission, a memo, etc.), or the user can manually select a menu to switch.

The controller 108 determines whether a predetermined key button is input for switching the character input mode through the key input unit 106, and switches to the designated character input mode when the key button is input.

In addition, the controller 108 detects a key button input through the key input unit 106 and the number of times the key button is input according to the switched character input mode. The character assigned to the key button is determined according to the number of key button inputs.

When the character input through the key button is determined as described above, the controller 108 controls the display unit 107 to display the determined character. The displayed characters may be Korean or English characters or characters of other countries not mentioned in the above embodiment, depending on the character input mode.

Hereinafter, a method of determining a character according to the key button and the number of times the key button is input will be described with reference to FIGS. 4 to 7 when inputting a character using the mobile communication terminal configured as described above.

4 is an exemplary view showing a keyboard layout of a mobile communication terminal according to the present invention.

Referring to Fig. 4, the keyboard of the present invention (four rows by three columns) is divided into two columns (1 column, 2 columns) from left to right and four rows (1 row to 4 rows) from top to bottom. Display and assign two terminal sounds of Korean in sequence. At this time, the last two consonants (ㅍ, ㅎ) in the order are assigned to the first column (column 1) button of the last row (line 4) of the keyboard.

In addition, the Korean single vowels are assigned to each button in the first row (three columns) from the right side to the left side of the keyboard and four buttons (1 to 4 rows) in the upper side to the lower side. At this time, the last four vowels (TT, ㅠ, ㅡ, ㅣ) are two in sequence in the first column (column 3) and the second column (column 2) from right to left of the last row (line 4) of the keyboard. Assign it and display it.

In this case, a double consonant, a consonant consonant, a consonant vowel, and the like, which are not displayed on the keyboard, may be input by combining the buttons even if they are not directly assigned to each button.

In addition, the alphabetic characters are displayed by assigning two characters in sequence to each of three buttons (1 to 3 columns) from the left to the right of the keyboard and four buttons (1 to 4 rows) from the top to the bottom. The last six letters (U, V, W, X, Y, Z) are sequentially placed in the second column (column 2) and the third column (column 3) from the left to the right of the last row (line 4) of the keyboard. Display by assigning one by one.

In this case, numbers are arranged by assigning one to each of three buttons (1 to 3 columns) from the left to the right of the keyboard and four buttons (1 to 4 rows) from the top to the bottom, but the last row in the sequence. In the first column (column 4), the * button is assigned to the first column (column 1), the second column (column 2), the last digit (0), and the third column (column 3).

5 is a table illustrating a consonant input method using a keyboard layout according to the present invention. For convenience of explanation, a consonant input method will be described based on the number buttons.

Referring to FIG. 5, a user presses a button to which a terminal sound to be input is assigned in order to input a terminal sound of Korean. At this time, the consonants assigned to the buttons are sequentially input according to the number of times the button is pressed.

For example, pressing the first button to which the consonants 'ㄱ, ㄴ' is assigned, enters 'ㄱ' once, and presses '2' twice to enter 'ㄴ'. Similarly, pressing the button 2 to which the consonants 'ㄷ, ㄹ' is assigned is inputted once 'ㄷ', and pressed twice to input 'ㄹ'. Hereinafter, since the input method of the remaining terminal sounds (ㅁ, ㅂ, ㅅ, ㅇ, ㅈ, ㅋ, ㅋ, ㅌ,, ㅎ) is also the same as the input method of the terminal sound, description thereof will be omitted.

On the other hand, in order to input the consonants that are not directly assigned to each button, the consonant constituting the consonants constituting the consonants may be further pressed once more.

For example, in order to input '중' among the Korean consonants (eg, ㄲ, ㄸ, ㅃ, ㅆ, ㅉ), the button 1 to which the constituent consonant 'ㄱ' is assigned can be input by pressing 3 times. Similarly, in order to input the consonant 'ㄸ', the second consonant 'c' can be input by pressing the button 2 to which the consonant 'c' is assigned three times. Hereinafter, since the input method of the remaining consonants is the same as the input method of the consonants, description thereof will be omitted.

In addition, in order to input a consonant that is not directly assigned to each of the buttons, the consonants constituting the consonant may be sequentially inputted by pressing buttons.

For example, '복' is the number 1 button assigned to 'a' and 'ㅅ' among the Hangul consonants (eg, ㄳ, ㄵ, ㄶ, ㄺ, ㄻ, ㄼ, ㄽ, ㄾ, ㄿ, ㅀ, ㅄ). Can be entered by pressing button 5 one time at a time. Similarly, the double consonant 'ㄵ' can be input by pressing twice the first button to which 'b' is assigned and then pressing the seventh button to which 'ㅈ' is assigned. Hereinafter, since the method of inputting the remaining consonant sounds is the same as the method of inputting the consonant sound, description thereof will be omitted.

6 is a table for explaining a vowel input method using a keyboard layout according to the present invention.

Referring to FIG. 6, a user presses a button to which a short vowel to be input is assigned in order to input a short vowel in Korean. At this time, the vowels assigned to the buttons are sequentially input according to the number of times the button is pressed.

For example, pressing the number 3 button to which the vowel 'ㅑ, ㅑ' is assigned once enters 'ㅏ' and presses twice to enter 'ㅑ'. Similarly, pressing button 6 to which the vowel 'ㅓ, ㅕ' is assigned once enters 'ㅓ', and pressing it twice enters 'ㅕ'. Hereinafter, since the input method of the remaining short vowels (ㅗ, ㅛ, TT, ㅠ, ㅡ, ㅣ) is also the same as the short vowel input method, description thereof will be omitted.

Meanwhile, in order to input a vowel vowel not directly assigned to each button, each button to which the vowel constituting the vowel vowel is assigned can be sequentially pressed.

7 is a table illustrating a method of inputting a double vowel using a keyboard layout according to the present invention.

For example, referring to FIG. 7, '9' among Korean vowels (eg, 예, ㅙ, ㅚ, ㅝ, ㅞ, ㅟ, ㅢ) is assigned to button 9 and vowel ㅏ You can enter it by pressing button 3 one by one each time. Similarly, double vowel 'ㅙ' presses button 9 once assigned vowel 'ㅗ', then press button 3 assigned vowel 'ㅏ' once and press button 0 assigned vowel 'ㅣ' 2 Press once to enter. Hereinafter, since the input method of the remaining double vowels is the same as the input method of the double vowels, a description thereof will be omitted.

On the other hand, in order to input the double consonant, the double consonant and the double vowel not illustrated above, it is obvious that the buttons to which the respective constituent terminal sounds or the constituent short vowels are pressed can be sequentially inputted according to the character composition order.

8 is a table for explaining an English character input method using a keyboard layout according to the present invention.

For example, referring to FIG. 8, when the English word 'WORD' is to be input, press button 0 assigned with 'W' three times, press button 8 assigned with 'O' once, and 'R' It can be entered by pressing the assigned button 9 twice and pressing the button 2 assigned 'D' twice.

In the conventional English keyboard layout, at least three alphabetic characters are allocated to one button, and in some cases, up to four alphabetic characters are used. However, in the case of the present invention, by assigning two alphabetic characters to one button as a basis and assigning up to three alphabetic characters, the number of input strokes can be reduced at least three times or more depending on the number of characters constituting a word compared to the conventional art. It works.

9 is a flowchart illustrating a text input method of a mobile communication terminal according to the present invention.

Referring to FIG. 9, when an arbitrary key button input for character input is detected (S101), the controller 108 determines a character input mode set in the terminal (S102). Based on the character input mode, the controller 108 selects a type of a character to be input and an input algorithm according to the type of the character (S103).

For example, the selection of the input algorithm is because the input algorithm is different depending on whether the character to be input is Korean or English.

In addition, the controller 108 detects the number of times of input of the key button (S104), and determines a corresponding character among the letters assigned to the key button according to the number of inputs based on the input algorithm (S105). When the input character is determined as described above, the controller 108 controls the display unit 107 to display the determined character (S106).

FIG. 10 is a table comparing input stroke numbers and time with a conventional character input method when inputting Korean characters according to the keyboard layout of the present invention.

Referring to FIG. 10, the character input method of the present invention for the same sentence is similar to the input stroke of the celestial method in the number of characters inputted, and is much larger than the easy (ez) Korean input method.

However, it can be seen that the present invention is shorter than the ez Korean input method in the character input time because the movement of the finger for consonant and vowel input is shorter than that of the ez Korean input method.

In addition, in the case of the Cheonjiin method, when inputting a character consisting of vowel + consonant + consonant, the input stroke is required to wait to recognize that the cursor is the next character input or to press a button for forcibly inputting the next character. It is similar to the input method of the present invention, but it can be seen that the actual input time is longer.

Of course, the input time may vary according to the user's keyboard mastery and experimental method.

Therefore, in the present invention, the experimenters who have not used the character input are divided into groups, the character input method for each group is trained, and the same sentence is inputted so that the reliability can be increased by measuring the time.
