Description

Character input method of mobile communication terminal and mobile communication terminal applying the same {METHOD AND TERMINAL FOR INPUTTING CHARACTERS}

The present invention relates to a text input method of a mobile communication terminal and to a mobile communication terminal using the same to easily input consonants and vowels when transmitting a text message using a mobile terminal such as a computer or a mobile communication terminal.

Generally, a keyboard, which is an input device of a computer, has a key layout structure in which one letter is assigned to one key. However, a mobile communication terminal such as a cellular phone or a PDA usually has a key arrangement structure in which several characters are assigned to one key because the area given to the keypad, which is an input device thereof, is relatively narrow. Therefore, various methods are used for text input when the size of the terminal is small such as a PDA or a mobile phone and the number of keys of the keypad for data input is small.

In particular, in the case of a PDA, since the size of the display is configured as large as possible within the limited size of the PDA itself, most of the PDA implements data input using a touch screen method using a stylus pen or a finger.

Here, the touch screen is a concept including a general touch screen for input by pressing a finger and a tablet (Tablet) for input by pressing or writing with a stylus pen.

For example, in the case of a mobile communication terminal including a touch screen PDA, a keyboard-like character table is displayed on a display to input characters, and the characters are touched by a finger, a stylus pen, or another tool. How to do is widely used.

Representative examples of such character input methods are 'Cheonjiin' and 'EZ Hangul', and the combination of letters is illustrated in FIGS. 1 and 2, for example, <name>, <blue>, <not>, respectively.

Among them, the arrangement of consonants and vowels in the celestial manner is shown in FIG. Its main feature is the combination of all vowels with three vowels: 'ㅣ (이)', '. (하 아아)', 'ㅡ ('). All vowels can be entered with three buttons. So you don't have to memorize the vowel keyboard, you can write them sequentially like you write with a pencil. However, there is a problem in that continuous input is impossible when the initial letter of the initial letter and the initial letter of the latter letter are the same letters or letters assigned to the same key. To solve this, you must press the direction key to give a separate signal or wait for a certain time (about 2 seconds) before you can continue input (e.g. foot height, foot light, each, country, flu, powerful, food, eating, wood carving, cut, tableware, Musical instrument, writer, right angle, illusion, tactile, tactile, chin, tyrant, academic, department, school, school district, semester, etc.)

In addition, the arrangement of consonants and vowels in the EZ Hangul method is made based on two-hand input by separating the consonants and vowel keys as shown in FIG. 2. In other words, by changing the basic consonants and vowels to create a letter, for example, press "ㅁ" one more time to "되고" and press it once more to change it from "Basic" to a complicated shape. '#' And '*' are used to add double consonants and strokes. By the way, this method requires a little time to get used to the printed key is small but hidden keys as shown in the keypad description. And '*' adds stroke and '#' creates double consonant, which increases the moving distance.

The present invention is to solve this problem, the object of the present invention is to provide a convenient text input method for both beginners and experienced users to easily input consonants and vowels when sending texts using a mobile communication terminal such as a mobile phone It is to provide.

In order to solve the above problems, a method for inputting a character to a mobile communication terminal using a character key assigned a plurality of characters to one key, the method comprising: checking whether there is an input of the character key; Analyzing the initial input when the character key is input, determining whether it is a consonant or a vowel, extracting first candidate character groups corresponding to key input data, and displaying the first candidate character group on a display; Extracting a second candidate character group corresponding to any one selected from among the first candidate character groups and including the selected first candidate character group, and giving a condition that is attached to the input character and falling conditions and displaying the second candidate character group on the display; ; Confirming which one of the second candidate character groups is selected; And receiving the selected second candidate character group as input data.

According to the present invention, a finger touch screen divided into five sensing areas and a text input method are described. More particularly, in a touch screen such as a mobile phone input by contact, a text input window on a screen when text input is performed. Is detected in four rectangular areas and five areas of the center area, and the input method can be derived from a combination of areas recognized by dragging on the screen (drag in contact). Unlike the need to find among multiple characters, and a few (five) recognition points to reduce the error recognition of the character, it is related to the finger touch screen divided into five detection areas that can be entered with your fingers, Also, consonants and consonants are quick and easy by displaying one character with one click or one drag. Provide convenience of input.

Hereinafter, a preferred embodiment of a mobile communication terminal and a character input method thereof according to the present invention will be described with reference to the accompanying drawings.

As shown in Figures 3 and 4, the mobile communication terminal of the present invention includes a main body portion provided with a plurality of key buttons, and a display portion for outputting so that the user can check the contents.

The main body is provided with key buttons for character input in a 3 * 4 arrangement, and five key buttons in the form of crosses are assigned as vowel input keys. It is indicated by the arrow keys and the center point (bottom), and the rest are assigned to the consonant input keys. In addition, a key tag including a consonant among the consonant input keys, for example, a key button of 'ㄱ', 'ㄷ', 'ㅈ', 'ㅈ', and 'ㅅ' may be provided with a recognition tag so that the user can easily recognize it. (In this embodiment, two dots are printed as identification tags on the upper side of each key button containing the double consonants.)

If the display unit presses any key button among the vowel input key or the consonant input key provided in the main body, the character and the associated sound corresponding to the key button are displayed in the cross-type touch input mode so that the user You can enter characters by touching. In this case, the touch input mode refers to a touch screen capable of continuously inputting coordinates by touching or dragging the coordinate input means.

Meanwhile, depending on the type of terminal, the main body or the display may be provided with a cross-shaped direction key, and the direction key may be configured to correspond one-to-one with the cross-type touch input mode.

As an example, the cross-shaped consonants will be described as follows. First, a selection consonant is displayed at the center of the cross array as a selection indication of the first selected consonant. The initial consonant is displayed to the left of the selected consonants in the cross arrangement. The double consonants are displayed to the right of the selected consonants in the cross array. And the lattice sound of the selection consonants or the relation sounds associated with the selection consonants are displayed on the upper side of the cross array. Finally, the cancel key is displayed below the cross array.

[Example 1]

When the [a] button is pressed on the key button, the consonant consonants are formed in a cross shape including a cancel key at the bottom and displayed in the touch input mode on the display. Thereafter, the user can select between consonants, consonants, and relational sounds, and after the selection, the vowels are implemented in a cross form on the display.

[Example 2]

Old sound cross consonants can be selected up, down, left, and right with the direction key to the selected "ㄱㄷ ㅂㅈㅅ" selection consonant center area. Consonant direction key input selection of the cross direction key can be selected by using a direction key on the display or by a touch pan or a finger on the touch screen screen.

The user can select the consonant consonant with the arrow keys.

Also, the terminal of the present invention extracts a character corresponding to a combination of button codes output by a plurality of preset button areas, a character corresponding to a plurality of button codes from a memory, and generates corresponding characters to display unit. It further includes a control unit for displaying.

Therefore, when coordinate data corresponding to each button area is input through the touch input mode, the controller generates a preset center button code, upper button code, right button code, lower button code, and left button code.

In this way, the control unit for generating each button code combines the button codes generated from the touch on the touch screen to output Korean or English, or when dragging, the start point button code and the end point are determined by judging the start point and the end point of the drag. Generates a button code and outputs Korean or English characters corresponding to the combination of the two codes. See Table 1 below for an example.

Next, a method of inputting text using the mobile communication terminal of the present invention will be described.

Character input method of the present embodiment is to input a character by using a key button assigned a plurality of character keys, 1) checking whether there is an input of the character key; 2) extracting the first candidate character groups corresponding to the key input data by analyzing the initial input when the character key is input, determining whether it is a consonant or a vowel, and displaying the first candidate character group on the display; 3) extracting the second candidate character groups corresponding to any one selected from among the first candidate character groups and including the selected first candidate character groups, and giving a condition that is attached to the input character and falling conditions and displaying them on the display; step; 4) selecting any one of the second candidate character groups and accepting the selected second candidate character group as input data.

The above-described steps will be described in more detail as follows.

1) The character array to be applied is applied to the key map of the mobile communication terminal.

2) In case of character input, the conditional sentence is analyzed to determine whether it is consonant or vowel and change the next character input state value.

3) In case of Hangul, it is necessary to define the conditions of sticking and falling. For example, if the consonant is a consonant, the next character is entered as a consonant because it is a falling condition. (Example: a + b = a)

4) If the consonant is a consonant and the next entered character is a vowel, it is entered as a condition to be pasted (e.g. a + ㅏ = a).

5) If the consonant is a consonant and the next character is a vowel and the next character is a consonant, it is entered as a condition for pasting (eg a + ㅏ + b = liver).

6) After the condition of 5), add and drop the letter according to what is entered after it. For example, in case of consonant + vowel + consonant + consonant, you need to define all the consonants according to the consonant (e.g. ㅇ + ㅏ + ㄴ + ㅎ = ,, ㅇ + ㅏ + ㄴ + ㅋ = ㅋ) and In the case of consonant + vowel + consonant + vowel, it is entered as a falling condition (e.g. a + ㅏ + b + ㅏ = kana).

In this regard, an example algorithm is shown in Table 2 below.

7) For the vowel key of the cross key, put the vowel point (bottom) in the middle and 'ㅣ' vowel on the left and right sides with the same value (ex: 7 = 35, 9 = 35).

8) The upper and lower sides of the vowel point (bottom bottom) have the same '-' vowel.

9) For character input, for example, when the numeric key 7 is' ㅣ ', 8 is vowel point' ˚ ', 9 is' ㅣ', and 7, 8 and 9 are pressed consecutively, 'ㅣ + ˚ + ㅣ = ㅐ Becomes. Since the same value is given, pressing the numeric key 7 → 8 → 7 and pressing 9 → 8 → 9 will give the same value.

10) After the consonant, only 'ㅣ' is input when the touch value is true on the numeric key 7, so it is currently in the 'ㅣ' input state.

11) If the drag value is true on the numeric key 7 after the consonant and false before the 8 comes, only the value of 'ㅣ' is entered and the condition that the next input value is determined is attached or dropped.

12) However, if the number keys 7 to 8 are dragged and the drag value before 9 becomes false, the result is that 7 and 8 are entered. (Example: a + <drag 7, 8: ㅣ + ˚ = ㅏ> ㅏ = a) Afterwards, depending on what the next value is, you go into the condition of pasting or falling.

A process of the character input method configured as described above will be described with reference to FIG. 5.

First, a key scan is performed in a mobile communication terminal to check whether a character is input through a keypad.

If it is determined that a character is input through the keypad, a code corresponding to the key is generated. When it is determined that the consonant is not a consonant with reference to the code generated as described above in FIG. 2, it is processed by the vowel processing process.

On the other hand, if it is determined that the input code is a consonant, the address of the phoneme is generated. Then, the phoneme code of the phoneme is generated with reference to the generated address.

Finally, the phoneme code generated above is transmitted to the automata to generate a predetermined Hangul code.

On the other hand, the number of button presses are important for entering text on a mobile phone, but economic movement is also important. And writing in Korean, like writing with a pencil, can help you become familiar with the keyboard quickly and be able to enter text intuitively. In view of this point, the character input method of the present embodiment provides convenience of consonant and vowel input by assigning a vowel combination from a plurality of characters as a cross direction key. That is, the representative vowels of the Korean vowel system, 양성, 양성 positive vowels and ㅓ, TT voice vowels are assigned to the vertical and horizontal arrows and horizontal or vertical, respectively, according to the present embodiment, the consonants and vowels are directly You can input them in order as you write.
