The present invention relates to a method and apparatus for easily inputting Hangul using a special key in a portable electronic communication device. More specifically, by introducing a special key that functions like a shift key on a computer keyboard to a keypad of a conventional portable electronic communication device, it is possible to quickly and easily input Korean characters by using another character button together with the special key. A method and apparatus are disclosed.

Today, the general public has been frequently writing and receiving short messages (SM) as well as phone calls to mobile communication terminals, and the demand for convenience and speed improvement of the method of inputting Korean characters into mobile communication terminals has increased. have.

On the other hand, as in Table 1, Korean keyboard input methods such as 'Cheonjiin' and 'eZ Hangul' developed by Samsung Electronics and LG Electronics, which occupy more than 70% of the domestic mobile communication terminal market, are developed and used. It is becoming.

1 is a plan view showing a keyboard combination of 'Cheonjiin', 'Cheonjiin' represents all vowels as a combination of cloth (·), ji (ㅡ), phosphorus (ㅣ). For example, the vowel 'ㅏ' is a combination of 'ㅣ' and '·', 'ㅑ' is a combination of 'ㅣ', '·' and '·', and 'ㅙ' is '·', 'ㅡ', It consists of a combination of 'ㅣ', '·' and 'ㅣ'. Consonants can be arranged by clicking and double clicking by arranging two to one key, and inputting the sound ('ㄲ', 'ㄸ', 'ㅃ', 'ㅆ', 'ㅉ') three times in a row It is to be done.

FIG. 2 is a plan view of a keyboard combination of 'eZ Hangul', with the basic consonants' ㄱ ',' ㄴ ',' ㄹ ',' ㅁ ',' ㅅ ',' ㅇ ', and' stroke 'and' By double consonant function, all consonants can be input. For example, the vowel 'ㄷ' is a combination of 'ㄴ' and 'stroke addition', and 'ㅈ' is a combination of 'ㅅ' and 'stroke addition'. The vowels of 'ㅋ', 'ㅌ', 'ㅊ' and 'ㄷ' are also made by combining 'stroke' with flat sound. For example, 'c' is made after combining 'b' with 'overwrite'. You will combine 'add strokes' to make 'ㅌ'. In addition, twin consonants such as 'ㄲ', 'ㄸ', 'ㅃ', 'ㅆ', 'ㅉ' are 'a', 'c', 'ㅂ', 'ㅅ', 'ㅈ' Is made by combining On the other hand, a layered collection of 'ㅑ', 'ㅕ', 'ㅛ', 'ㅠ' and the like is configured by combining 'add stroke' function with 'ㅏ', 'ㅓ', 'ㅗ', and 'TT'.

The Cheonjiin method has a reputation for intuitive input, but has a disadvantage of pressing a button several times in order to input a vowel that is necessarily included for each Korean syllable. That is, since strokes are input to one input in order to minimize key assignment for vowels, there is a problem that keys must be input as many strokes as vowels for vowel input. For example, in order to input 'ㅖ', '·', '·', 'ㅣ', and 'ㅣ' must be selected in order, thereby increasing the number of key inputs. In addition, the eZ Hangul method is irregular in the arrangement of keys (key), and due to the structural characteristics of the keyboard required a lot of time and effort to use familiar.

As described above, the Korean input methods used by most mobile communication terminal users have a large number of key inputs even when a long sentence is written because the average number of key inputs required to display a single Korean character is large as shown in FIG. 5. Since there is a lot of moving distance between buttons when inputting, the time required for completing a text message is long and there are many inconveniences in use.

In order to solve this problem, the present invention, by introducing a special key having the same function as the Shift key on the computer keyboard to the keypad of the conventional portable electronic communication device to use a different character button at the same time, It is an object of the present invention to provide a method and apparatus for reducing the average number of key inputs required for Hangul input and also shortening the moving distance between buttons when inputting the Korean text in a long text.

According to a first object of the present invention for achieving the above object, in the method for processing the phoneme input by placing the consonant, vowel and special keys of the Hangul on the keypad as an input means of a portable electronic communication device including a mobile communication terminal If the terminal sound (e.g. 'ㄱ') is placed on the keypad while the special key is pressed, it is judged as a double consonant (e.g. 'ㄲ') corresponding to the terminal sound, and the key is placed on the keypad while the special key is pressed. When a vowel (for example, 'ㅏ') is inputted, a Korean electronic input method using a special key is provided in a portable electronic communication device characterized in that it is determined as a vowel (eg, 'ㅐ') added to the vowel. .

According to a second object of the present invention, a keypad for inputting and processing Korean characters by placing consonants, vowels, and special keys on a keypad as an input means of a portable electronic communication device including a mobile communication terminal, wherein the keypad is pressed while the special key is pressed. When the terminal sound arranged in the input is input, it is judged as a double consonant corresponding to the terminal sound, and when the vowel placed on the keypad is input while the special key is pressed, it is determined that the ㅣ is added to the vowel. In the portable electronic communication device to provide a keypad for inputting Hangul using a special key.

Hereinafter, a Hangul input method using a special key in a portable electronic communication device according to an exemplary embodiment of the present invention will be described.

For example, in the case of inputting subtraction, first pressing the fourth key input button 408 twice while pressing the special (FN) key 420 forms a 'ㅃ' and a special (FN) key 420. If the third key input button 406 is pressed while the button is kept pressed, 'ㅐ' is added and subtracted to form. Here, the special (FN) key 420 kept pressed and the fifth key input button 410 is pressed twice, the 'd' is added to form a 'subtracted'. When the seventh key input button 414 is pressed twice, ㅅ is formed and when the sixth key input button 412 is pressed while the special (FN) key 420 is kept pressed, ㅔ is added. 'Three' is formed. Thereafter, when the special (FN) key 420 is released and the seventh key input button 414 is pressed, 'ㅁ' is added to form 'sem', and thus the word 'subtraction' is completed.

As another example, we will look at the process of entering 'myself' and compare the number of times in 'Cheonjiin' and 'eZ Hangul' methods for entering the same word.

The present invention first presses the fourth key input button 408, and then presses the third key input button 406 while pressing the special (FN) key 420 to input 'my'. When the eighth key input button 416 is pressed while the special (FN) key 420 is kept pressed, 'ㅉ' is formed immediately.The third key input button 406 is released after the special (FN) key 420 is released. ) And the first key input button 402 are sequentially pressed to form a pair. Then, while pressing the special (FN) key 420, press the first key input button 402, release the special (FN) key 420, and then press the twelfth key input button 424 and the eleventh key input button ( 422) in turn, '꿍' is formed to complete 'my close'. The total number of keystrokes is 10.

On the other hand, for 'eZ Hangul', press 'ㄴ' key, press 'ㅏ' key, 'Add stroke' key to make 'My', press 'ㅅ' key and press 'Add stroke' key to After making it, press the 'double consonant' key to make 'ㅉ', and then press 'ㅏ' and 'ㄱ' to make 'pair'. Next, press the 'a' key and the 'double consonant' key to make 'ㄲ' and then press the 'TT' and 'ㅇ' keys to make '총'. A total of 13 keystrokes are required and the distance between the buttons many. 'Cheonjiin' needs more key input. Press 'n' key, press 'ㅣ' key, press '·' key and 'ㅣ' key to make 'My', press 'ㅈ' key three times. Press 'ㅣ' and '·' and 'a' to make 'pair', then press 'a' three times and press '-' and '·' and 'ㅇ' to press '키' You need to create a total of 16 keystrokes.

That is, the Hangul input method according to the embodiment of the present invention is a method of repeatedly pressing or releasing and pressing the special (FN) key 420 without moving the position with one finger and inputting another character input key with another finger. In this way, it is possible to minimize the moving distance between buttons for character combinations and to reduce the number of inputs.

Meanwhile, a mobile communication terminal to which a Korean input method and apparatus using a special key according to an embodiment of the present invention is applied is a PDA (Personal Digital Assistant), a cellular phone, a PCS (Personal Communication Service) phone, a GSM (Global System for Mobile) Phones, wideband CDMA (W-CDMA) phones, CDMA-2000 phones, and Mobile Broadband System (MBS) phones, which are mobile phones to be used in the fourth generation of the system currently being discussed, and the like, and the present invention relates to a television remote control or a wired telephone. It may be applied to a touch screen.

The above description is merely illustrative of the technical idea of the present invention, and those skilled in the art to which the present invention pertains may make various modifications and changes without departing from the essential characteristics of the present invention. Therefore, the embodiments disclosed in the present invention are not intended to limit the technical idea of the present invention but to describe the present invention, and the scope of the technical idea of the present invention is not limited by these embodiments. The protection scope of the present invention should be interpreted by the following claims, and all technical ideas within the equivalent scope should be interpreted as being included in the scope of the present invention.

As described above, according to the present invention, the conventional portable electronic communication device is equipped with a special key and executes another character input key at the same time as the special key, thereby making Hangul input faster and easier.                     

Hereinafter, the present invention uses the special key and the character input key together, thereby reducing the average number of key inputs required for Korean input and also shortening the moving distance between buttons during input, thereby making it possible to more quickly and easily make long Korean input. This will be explained by comparing and analyzing with other Hangul input methods such as 'Cheonjiin' and 'eZ Hangul'.

First, the principle of Korean vowel system is as follows. The Korean vowel system consists of eight short vowels such as 'ㅏ', 'ㅓ', 'ㅗ', 'TT', 'ㅐ', 'ㅔ', 'ㅡ' and 'ㅣ' and a combination of these short vowels. 7 'composite vowels' including', 'ㅙ', 'ㅚ', 'ㅝ', 'ㅞ', 'ㅟ', 'ㅢ', and 'ㅑ', 'ㅕ' with a combination of yod and short vowels It consists of six 'collects' such as',', ',' ㅠ ',' ㅒ 'and' ㅖ '.

Next, the constitution principle of consonants is as follows. Korean consonants consist of 10 'terminal consonants' such as 'ㄱ', 'ㄴ', 'ㄷ', 'ㄹ', 'ㅁ', 'ㅂ', 'ㅅ', 'ㅇ', 'ㅈ', 'ㅎ' Four 'sounds' (rough), such as 'ㅋ', 'ㅌ', 'ㄷ', 'ㅊ' and five ',' '', 'ㄸ', 'ㅃ', 'ㅆ', 'ㅉ' It is composed of 'double sound'.

On the other hand, each phoneme of the consonants and vowels as described above actually differs in frequency, and the frequency of phonemes used in Korean documents may vary slightly depending on the type of document. Tables 2 and 3 show the frequency of Korean consonants and vowels based on statistics from 'Analyzing Korean Frequency of Use' (Kim Heung-Kyu, Kang Beom-Mo, Computer and Humanities Series 1, Korea University Institute of Ethnic Culture, 1997). present.                     

As such, there is a big difference in the frequency of use of each phoneme of Hangul. In order to compare the average number of key inputs required for Hangul input, it is weighted by the actual use frequency for each phoneme, rather than simply comparing the number of inputs required for each phoneme. It would be a more reasonable comparison to make a comparison.

FIG. 5 shows the Korean input method and the input method of the present invention, which are applied by the top three companies such as Samsung Electronics, LG Electronics, and Pantech among domestic mobile communication terminal manufacturers, as shown in Table 1, by the number of simple phonemes and each phoneme. This table shows the comparison of the number of inputs to which the weight is applied according to the frequency of use.

When the ratio of consonants and vowels in Korean input is 0.6: 0.4, multiply each by the percentage of each phoneme in Table 2 and Table 3 to calculate the weight for each phoneme. In other words, the percentage of 'b' is 14.96% in Table 2, multiplied by 0.6, the use of consonants, the weight is 0.1496 X 0.6 = 0.0898, and the weight of 'ㅓ' is 10.67% in Table 3 Multiplying the ratio 0.4 by 0.1067 X 0.4 = 0.0427.

On the other hand, the number of key input required for each phoneme input is different depending on the Hangul input method, for example, when inputting 'ㄸ', the present invention requires two inputs with a special key + 'c' arranged, and two inputs are required. And the Pantech method requires three inputs of the key to which the 'c' is placed, and the eZ Hangul requires three inputs with the 'n' key + 'add stroke' key + 'double consonant' key input.

By multiplying the weights for each phoneme before the number of key presses required for each phoneme input, the degree of the number of times that key input is required in actual Hangul input can be obtained. In addition, if the sum of the number of input weights applied to each phoneme is summed by consonants and vowels, the average number of inputs can be compared for each Hangul input method.

That is, when comparing the statistics of the last row in Figure 5, although the present invention is somewhat more than the conventional method in the input number of consonants only, the input of the vowel shows a large difference in the entire Hangul input that must write both consonants and vowels Comparing with, it can be seen that the number and degree of input is much lower. This is only a comparison of one letter, but if you enter a long sentence, the number and degree of entry will be much more different.

In addition, the present invention is a method that one finger is repeatedly pressing or releasing only a special key to enter another character input key with another finger, even when the same number of inputs by reducing the finger movement distance between the buttons when entering the long character The effect is to significantly reduce the time and inconvenience.
