The present invention relates to a character input apparatus, and more particularly, to a character input apparatus capable of inputting Korean and English in the same order as a user can easily recognize and write the position of the keyboard.

With the rapid development of communication technology, personal terminals such as mobile communication terminals (mobile phones), PDAs, etc., which can perform voice and data communication while moving, have been developed and widely used, and the performance of these personal terminals is improving day by day. In particular, mobile communication terminals have become indispensable necessities in modern social life and provide users with various additional functions such as providing video over the Internet, MP3, text transmission, as well as simple telephone functions.

On the other hand, for example, in the case of the students who use the mobile communication terminal most frequently, the text transmission function among the various additional functions is that the user of the mobile communication terminal can use the text transmission function more than the voice call which is the main function of the mobile communication terminal. One of the most common add-on features.

More specifically, in the case of a general mobile communication terminal, a plurality of phonemes are placed on each of the input keys from 0 to 9, and the corresponding continuous key is pressed to select consonants or vowels to be input according to the number of presses. Consonants are placed on each input key and vowels are combined using Cheonjiin (·, ㅡ, ㅣ). Naragle 2000.

FIG. 5 is a plan view schematically illustrating a combination of a keyboard unit for inputting characters using a continuous pressing method in a conventional mobile communication terminal.

As shown, in order to enter characters in the keyboard of the general mobile communication terminal, basic consonants (ㄱ, ㄴ, ㄷ, ㄹ, ㅁ, ㅂ, ㅅ, ㅇ, ㅈ, ㅋ, ㅋ, ㅍ, ㅌ, ㅎ) For example, input keys 1, 4, 5, 7, 8, *, 0, and basic vowels (ㅏ, ㅑ, ㅓ, ㅕ, ㅗ, TT, ㅠ, ㅡ, ㅣ) are input keys 2, 3 , 6, 9, and #, but two each on one input key to be recognized by clicking and double-clicking. In addition, the sound (ㄲ, ㄸ, ㅃ, ㅆ, ㅉ) is to be recognized as three consecutive clicks.

'Cheonjiin' method is to disassemble the vowels of Hangeul into thousand (·), ji (ㅡ), and phosphorus (ㅣ) and place them on the input key of the keyboard.

Accordingly, in the keyboard 110, the symbols '⊂', '⊃', '∪', and '∩', which are mainly used in English input, are respectively denoted by the second input key 112, the fourth input key 114, and the second input key. 6 input key 116, the eighth input key 118 is disposed, the fifth input key (115) with the 'ㅣ' symbol is most often used in English input

Since the structure is formed, the user can easily remember the position of the keyboard as well as input English in the same order as the handwriting with minimal movement.

Hereinafter, with reference to Table 2 will be described with respect to the alphabet input method according to another embodiment of the present invention.

Table 2 is a table for explaining the alphabet input method according to another embodiment of the present invention.

The alphabet is input by the sequential combination of input keys described in Table 2, and every alphabet is generated by two keystrokes. More specifically, for example, when the user wants to input the letter 'D', the user presses the fifth input key 115 and the sixth input key 116 provided on the keyboard unit 110, and a controller to be described later. In operation 130, the input symbols may be sequentially combined to generate an alphabet letter 'D' and output to the display unit 120.

On the other hand, among the plurality of symbols for inputting the alphabet, '…' The ninth input key 119 in which the symbol 'is disposed is an input key used when an alphabet is generated by one key input, which will be described in detail later.

On the other hand, in the keyboard 110, a period symbol '·' is further disposed on the first input key 111, and is used when switching from Korean input or English input to numeric input or from Korean input and English input to numeric input. And an eleventh input key 110a used for switching from a Korean input to an English input or an English input to a Korean input.

The display unit 120 is a liquid crystal display device provided in a general personal terminal such as a mobile communication terminal or a PDA, and may be implemented as a small display means such as, for example, an LCD, and a symbol according to a key input of the keyboard unit 110. Of course, the syllables and alphabets generated by the controller 130 to be described later are displayed.

The controller 130 controls not only the whole apparatus, but also generates consonants and vowels by sequentially combining the corresponding symbols according to key values input through the plurality of input keys 111 to 119 provided in the keyboard unit 110. Of course, the syllables and vowels are combined to generate and output syllables. More specifically, the controller 130 includes the consonant combination unit 131, the vowel combination unit 132, and the syllable combination unit 133 as described above.

The consonant combination unit 131 generates consonants by sequentially combining corresponding symbols according to key values input from an input key used for consonant input. For example, when a key value is input from the fifth input key 115 where 'ㅡ' is disposed and the seventh input key 117 where the symbol 'ㅅ' is arranged, the consonant combination unit 131 may display a corresponding symbol ('ㅡ'). 'Symbol' and 'ㅅ' symbol) are sequentially combined to generate a consonant 'ㅈ'.

The vowel combination unit 132 sequentially generates corresponding vowels according to key values input from an input key used for vowel input. For example, when a key value is input from the third input key 113 with the symbol 'ㅣ' and the sixth input key 116 with the symbol '·', the vowel combination unit 132 may display the symbol (' ㅣ 'symbol and' · 'symbol) are sequentially combined to generate a vowel' ㅏ '.

The syllable combination unit 133 sequentially combines the consonants and vowels generated by the consonant combination unit 131 and the vowel combination unit 132 to generate one syllable, and also generates the syllables when generating the syllables. Recognize. That is, the syllable combination unit 133 sequentially combines the consonants 'ㅈ' generated by the consonant combination unit 131 and the vowel combination unit 132 and the vowel 'ㅏ' in order to form one syllable 'Z'. Is generated and output to the display unit 120.

For example, if a user wants to input a syllable of 'ham', the user sequentially inputs each input key in which 'ham: ㅣ, ㅡ, ㅇ, ㅣ, ·, ㄴ, ㄱ' is arranged in the same order as the handwriting. If you press and hold the input key 112 that is 'b' is the final syllable combination syllable combination unit 133 recognizes this syllable is completed, and outputs to the display unit 120. That is, the syllable combination unit 133 recognizes the end of syllable and generates the syllable when the key value input from any one of the plurality of input keys provided in the keyboard unit 110 lasts for a predetermined time. When inputting, the final syllable is connected with the initial syllable of the syllable to be input, thereby preventing other consonants from being generated.

Meanwhile, the controller 130 according to another embodiment of the present invention generates alphabets by sequentially combining the corresponding symbols according to key values input from two input keys during English input, and outputs the alphabet to the display unit 120. That is, for example, when the alphabet A is input, the user sequentially orders the second input key 112 where the symbol of '∩' is arranged and the third input key 113 where the symbol of '-' is arranged. In this case, the controller 130 sequentially combines the symbols ('∩' and 'ㅡ') according to the key value input from the second input key 112 and the third input key 113. 'A' is generated and output to the display unit 120.

On the other hand, among the plurality of symbols for inputting the alphabet, '…' 'Is a symbol used when the alphabet is generated by one key input. For example, when the alphabet' C 'is input, the user inputs the fourth input key 114 in which the symbol' ⊂ 'is disposed. Wow '… Is generated by pressing the ninth input key 119 in which the symbol 'is disposed. That is, when the alphabet is generated by one key input as in the alphabet 'c', the input key is arranged with a symbol having the same shape as the alphabet, By pressing the ninth input key 119 in which the symbol of 'is arranged, the controller 130 controls the'. When a key value corresponding to a symbol of 'is inputted, it recognizes that the alphabet currently being input is an alphabet generated by one symbol, and outputs only the input preceding symbol' ('to the display unit 120 without any combination.

As described above, the character input device 100 according to the present invention is generated by one key input, such as 'C, I, N, O, U', in addition to the alphabets generated by two key inputs when entering English. Even in the alphabet, '…' By using the ninth input key 119 in which the symbol 'is disposed, an effect that can prevent a typo problem caused by the alphabet (C, I, N, O, U) generated by one key input can be prevented. Have

That is, when the letters 'C, I, N, O, U' are generated by one key input, for example, the user wants to input the letter 'CC', the user inputs the fourth input key 114 twice. Although it is pressed, the controller 130 generates an alphabet letter 'E' by sequentially combining the symbols '⊂' disposed on the fourth input key 114 of the keyboard 110 to generate a character that is not desired by the user. It is possible to prevent the occurrence problem.

Therefore, the user can input the English in the same order as the handwriting, as well as all the alphabets are generated by two key inputs, thereby simplifying the English input process so that the user can enter the English conveniently and efficiently. .

As described above, in the character input apparatus according to the present invention, symbols mainly used in consonant input are arranged in a lattice (ㅁ) structure, and the most commonly used '-' symbol is arranged in the center of the keyboard part. Since the symbols used in the keyboard are disposed at the rightmost side of the keyboard, the user can easily recognize the position of the keyboard and has the advantage of allowing the user to input Korean characters in the same order of writing by minimizing the moving distance.
