Description

Apparatus for inputting Korean alphabet for mobile terminal using restricted umber of Keys}

The present invention relates to a Hangul input device of a mobile communication terminal, and to easily configure a Hangul keyboard layout and simplify the input method of a mobile communication terminal. It relates to a Hangul input device.

Input methods used in the Korean input system of the conventional mobile communication terminal have been as follows.

The first is the coordinate method, which includes Hyundai Electronics 'Gulliver' and SK Teletech's 'Sky'. This method uses the left and right keys to move the cursor on the LCD screen.

The second is the continuous pressing method, which is adopted by LG C & T's 'Scient' old model and Motorola's 'Stack', which uses two to three consonants and vowels on one key. The consonants or vowels to be entered are displayed according to the number of times of pressing five times.

Third, the dismantling method of the phoneme is adopted by Samsung's Cheonjiin or LG ICT's Naragle 2000, which disassemble one consonant or vowel into smaller basic shape units and display them in combination. That's the way it is.

5 is a plan view showing a keyboard combination of 'Cheonjiin', 'Cheonjiin' represents all the 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 input 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.

'Naratgle 2000' (Fig. 6) is a basic consonant of 'ㄱ', 'b', 'ㄹ', 'ㅁ', 'ㅅ', 'ㅇ', and can enter all the consonants by the 'overwrite' function It would be. For example, the vowel 'ㄷ' is a combination of 'b' and 'overwriting', and 'ㅈ' is a combination of 'ㅅ' and 'overwriting'. The vowels of 'ㅋ', '' ',' ㅊ 'and' ㄷ 'are also made by combining' overwriting 'with flat sound. For example,' c 'is made after combining' b 'with' overwriting '. The combination of 'overwrite' makes 'ㅌ'. 'ㅑ', 'ㅕ', 'ㅛ', 'ㅠ', etc. are composed of the 'side', ',', 'ㅗ', 'TT' by combining the 'side by side' function.

The conventional methods described above have been problematic in that it takes a lot of time and inconvenience to display Korean characters because the average number of key inputs required to display Korean characters is very large.

First of all, the coordinate method should be strictly referred to as selection rather than input, and the continuous pressing method is almost out of practical terms due to too many key presses. In contrast, the dismantling method has been mainstream in recent years for its practicality. This method raises the following problems.

First, there is a need to reconstruct consonants and vowels into several basic shapes, which impairs directness, which is easy to understand and learn.

Secondly, this causes inconvenience in use. This is cumbersome because multiple keys must be used to implement one element.

Third, as a result, the number of input strokes becomes very large and the input time becomes long.

Fourth, in a system in which two consonants are arranged in the same key, when two consonants are contiguous or the same consonants appear consecutively, a problem arises in that a certain time must be waited. This creates a problem with the possibility of immediate entry.

The present invention was created to solve the above problems, firstly to improve the directivity, in particular to improve the directivity of the vowel keyboard can be easily understood and used, secondly to eliminate the hassle of use, and thirdly The Korean input device of the mobile communication terminal which reduces the input stroke number, fourthly shortens the input time, and fifthly increases the possibility of instantaneous input of phonemes assigned to the same key. To provide for that purpose.

And a Hangul processor for recognizing the overlap vowel and outputting a key code for a syllable combined with a consonant. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Hereinafter, a configuration and an operation relationship of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a plan view showing a keyboard combination of a first embodiment of a Hangul input system of the present invention. The keyboard combination includes a first Hangul input key (1) having consonants 'ㄱ' and 'ㅋ' disposed on the same key; A second Hangul input key (2) having consonants 'b' and 'ㄹ' arranged on the same key; A third Hangul input key (3) having consonants 'ㄷ' and 'ㅌ' arranged on the same key; A fourth Hangul input key 4 having consonants 'ㅂ' and '과' arranged on the same key; A fifth Hangul input key 5 having consonants 'ㅅ' and 'ㅎ' disposed on the same key; A sixth Hangul input key 6 in which consonants 'ㅈ' and 'ㅊ' are arranged on the same key; A seventh Hangul input key 7 having consonants 'ㅇ' and 'ㅁ' arranged on the same key; An eighth Hangul input key 8 in which the vowels 'ㅏ' and 'ㅐ' are arranged on the same key; A ninth Hangul input key 9 in which the vowels 'ㅗ' and 'TT' are arranged on the same key; A tenth Hangul input key 10 in which the vowels 'ㅓ' and 'ㅔ' are arranged on the same key; An eleventh Hangul input key 11 having 'falling out' for fast phoneme determination between phonemes assigned to 'overlap' and the same key to form an overlap on the same key; The vowel 'ㅣ' and 'ㅡ' are composed of the twelfth Hangul input keys 12 arranged on the same key.

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. Seven 'complex vowels' including', 'ㅙ', 'ㅚ', 'ㅝ', 'ㅞ', 'ㅟ', 'ㅢ', and 'ㅑ', 'ㅕ' with a combination of yod and short vowels It consists of six 'stacks' such as',' ㅛ ',' ㅠ ',' ㅒ 'and' ㅖ '. In other words, the Korean vowel system is formed based on eight 'short vowels'. Reflecting these linguistic principles on the keyboard, eight 'short vowels' are arranged on four keyboards, 'composite vowels' are composed of their combinations, and 'single vowels' are combined with 'short vowels' and 'overlap' keys. Combination can be used to create the most direct combination of keyboards that match Korean users' perception. And since the vowels are not disassembled, the number of inputs is minimized. However, the only problem that can be raised at this time is the possibility of immediate input between vowels assigned to the same key depending on the combination method of short vowels. Therefore, in order to eliminate this problem, by assigning mutually configurable short vowels to different keys, 'ㅏ' and 'ㅐ', 'ㅗ' and 'TT', 'ㅓ' and 'ㅔ', 'ㅡ' and 'ㅣ' Each was arranged on the same key.

In other words, the vowel keyboard combination of the present invention is arranged in the same key, 'ㅏ' and 'ㅐ', 'ㅗ' and 'TT', 'ㅓ' and 'ㅔ', 'ㅡ' and 'ㅣ', respectively, with only four keys. By expressing all the short vowels, the complex vowels using a combination of them, and using the 'overlap' key to express 'ㅑ', 'ㅕ', 'ㅛ', 'ㅠ', 'ㅒ', 'ㅖ', It improves the directivity of the vowel keyboard, improves the convenience of use, reduces the number of typing, shortens the input time, and improves the possibility of immediately inputting the phonemes assigned to the same key.

Comparing the vowel input system of the present invention with the conventional vowel input systems of 'Cheonjiin' and 'Naratgle 2000' can easily see the comparative advantage. The following table shows a comparison with Cheonjiin.

When the present invention and Cheonjiin have the same number of strokes, there are three vowels, while the present invention has one more stroke than Cheonjiin, while the present invention has 17 fewer strokes than Cheonjiin. In conclusion, the present invention has fewer strokes in 17 vowels than 'Cheonjiin'.

The following table shows a comparison of vowel input (simple) strokes with Naragle 2000.

As shown in the table, the present invention has only one vowel when the number of strokes is greater than 'Naratgle 2000', and 11 vowels for the same number and same key movement, while four vowels for the same stroke but fewer key movements. In the present invention, when the number of strokes is smaller than 'Naratgle 2000', three vowels are used. This is because the Naragle 2000 does not have 'ㅐ' and 'ㅔ', so it is seen in the case of six collections such as 'ㅐ', 'ㅐ', 'ㅒ', 'ㅖ', 'ㅙ' and 'ㅞ'. This is the result of more key movements than the invention. In conclusion, considering the number of strokes and key movements, the present invention is superior to nine collections than 'Naratgle 2000'.

The Hangul input operation of the present invention will be described.

In all key operations, a single click recognizes the left phoneme assigned to the key and a double click the right phoneme. That is, in the case of the first Hangul input key (1), if it is clicked once, it is 'ㄱ', and if it is double clicked, it is converted to 'ㅋ'. Click once to 'ㄹ', for the third Hangul input key (3), click once for 'ㄷ', double click for 'ㅌ', and for the fourth Hangul input key (4), click once 'ㅂ', double click to 't', the fifth Korean input key (5), click once to 'ㅅ', double click to 'ㅎ', and sixth Korean input key (6) In the case of single click, 'ㅈ', double click to 'ㅊ', and in the case of the seventh Hangul input key (7), click once to 'ㅇ', double click 'ㅁ', In case of input key (8), click once to 'ㅏ', and double click to 'ㅐ'. In case of ninth Korean input key (9), click once to 'ㅗ', double click to 'TT' ', In the case of the 10th Korean input key 10, click once to When the "ㅔ ', in the case of 12 Hangul input key 12, clicking once on clicking' l ', is recognized as a double" sul ".

In addition, in the case of the eleventh Korean input key 11, it is recognized as 'overlap' when clicked once and 'missing' when clicked twice.

The function of the 'overlap' key is as follows.

The first is to click once (or twice) on the keys with consonants 'ㄱ', 'ㄷ', 'ㅂ', 'ㅅ', and 'ㅈ' and click once on the eleventh Hangul input key (11). Gyeonggi consonants 'ㄲ', 'ㄸ', 'ㅃ', 'ㅆ', 'ㅉ' are input.

Secondly, if you enter the vowel 'ㅏ', 'ㅓ', 'ㅗ', 'TT', 'ㅐ', '를' and click the eleventh Hangul input key 11 once, each of the vowels' ㅑ ',' 'ㅕ', 'ㅛ', 'ㅠ', 'ㅒ' and 'ㅖ' are entered.

The function of the 'fall out' key is as follows.

For a key that has two consonants assigned to one key, when you want to play the left consonant and the right consonant consecutively (that is, when you try to play the same consonant consecutively) (I.e., two consecutive left consonants, two consecutive right consonants), a conventional system must wait for a certain time until the currently inputted phoneme is determined. However, instead of waiting for a certain amount of time, one consonant can be played and then the 'miss' key can be clicked to immediately confirm the current consonant and re-enter it.

The system assigns the 'overlapping' and 'falling out' functions to a single key, 'overlapping' allows for 'one click' and 'falling out' with two clicks. However, the second Hangul input key (b / ㄹ) and the seventh Hangul input key (ㅇ / ㅁ) without overlapping can be re-entered immediately after confirming the currently entered consonants with a single click. have.

For example, if the second Hangul input key (2) is clicked once and 'n' is inputted and the eleventh Hangul input key (11) is double-clicked, it immediately determines 'b' and enters the next input ready state. Switch. Therefore, once the second Hangul input key 2 is clicked again, 'b' can be directly inputted when 'b' is clicked twice.

Meanwhile, complex vowels such as 'ㅘ' 'ㅙ' 'ㅚ' 'ㅝ' 'ㅞ' 'ㅟ' 'ㅢ' are formed by the combination of the corresponding short vowels. That is, 'ㅘ' is a combination of 'ㅗ' and 'ㅏ', 'ㅙ' is a combination of 'ㅗ' and 'ㅏ', 'ㅚ' is a combination of 'ㅗ' and 'ㅣ', and 'ㅝ' Is a combination of 'TT' and 'ㅓ', 'ㅞ' is a combination of 'TT' and 'ㅔ', 'ㅟ' is a combination of 'TT' and 'ㅣ', and 'ㅢ' is 'ㅡ' and Combination of 'ㅣ', that is, click 'ㅣ / ㅡ' key twice to make 'ㅡ', and after a certain time, click 'ㅣ / ㅡ' key once to form 'ㅢ'.

However, when you want to hit '외에도', in addition to this method, press the 'ㅣ / ㅡ' key and press the '* (overlapping)' key to form 'ㅢ' directly.

On the other hand, the system has different application methods for the 'overlap' and 'missing' functions. First, the operation of the 'falling' key and the 'overlap' key is the same with one click, but the 'missing' key is the consonant input. Apply only after, and the 'overlap' key is applied only after vowel input. In this case, when inputting a hard consonant such as 'ㄲ' or '등', the corresponding terminal sound key is clicked three times.

The following is how to use the 'overlap' key as a shift. In other words, inputting a terminal sound or a short vowel while pressing the 'overlap' key causes the hard or consonant to be input. In this case, the 'overlap' is shifted and the 'falling out' is operated by one click.

The Hangul input process of the present invention will be described below.

For example, to input 'right', click the first Korean input key (1) once to enter 'ㄱ', and then click the ninth Korean input key (9) twice to enter 'TT', Click the tenth Korean input key (10) once to input 'ㅓ', and click the second Korean input key (2) once to enter 'b', and after a certain time the second Korean input key ( 9) Click twice to input 'ㄹ', and click the 12th Hangul input key 12 once to input 'ㅣ'. At this time, instead of entering 'b' and waiting for a certain time, double click the 11th Korean input key 11 to confirm the input of 'b' and click the 2nd Korean input key 2 twice. You can also enter 'ㄹ'.

With reference to the table below, the input process of the present invention and the prior art is compared in terms of only a simple number of inputs (without considering the number of key movements). That is, two clicks and three clicks of the same key were calculated to be equal to the number of inputs of two and three times of the other key, respectively.

As shown in Table 3 at the time of 'Why?', The present invention requires 12 key inputs, 18 key inputs for 'Cheonjiin', and 13 key inputs for Naragle 2000. It can be seen that is significantly shortened compared to the prior art.

As shown in Table 4 at the time of the input of 'sin and punishment', the present invention undergoes 10 key inputs, 14 key inputs for 'heavenly man', and 13 key inputs for Naragle 2000. It can be seen that the key input process is considerably shorter than in the related art.

As seen above, only the number of inputs can be seen that the number of inputs is smaller than that of the prior art. Moreover, as mentioned above, two to three repetitions of the same key were simply calculated the same number of times as two and three inputs of different keys, respectively, but repeated input of the same key takes much longer than repetitive input of other keys. Since it takes less time and there is no movement between keys, considering the above, the present invention is an improved system compared to 'Cheonjiin' that moves a lot when entering a vowel in input time and hassle. It's a significant improvement over the 2000's.

In addition, it will be easy to understand the advantages of the present invention in view of the fact that the prior art is greatly reduced compared to the present invention in directivity and troublesome sound.

FIG. 2 is a plan view showing a second embodiment of the keyboard combination of the present invention, which differs from the arrangement of consonants in FIG. In FIG. 2, the arrangement of consonants is applied in a lexical order. That is, the first Hangul input key (1) having consonants 'ㄱ' and 'b' arranged on the same key; A second Hangul input key (2) having consonants 'ㄷ' and 'ㄹ' disposed on the same key; A third Hangul input key (3) having consonants 'ㅁ' and 'ㅂ' arranged on the same key; A fourth Hangul input key (4) having consonants 'ㅅ' and 'ㅇ' arranged on the same key; A fifth Hangul input key 5 in which consonants 'ㅈ' and 'ㅊ' are arranged on the same key; A sixth Hangul input key 6 in which consonants 'ㅋ' and 'ㅌ' are arranged on the same key; The difference is that the consonants 'ㅍ' and 'ㅎ' are provided with the seventh Hangul input key 7 arranged on the same key.

Even if the keyboard combination of FIG. 2 is applied, the key manipulation and application rules of the key combination shown in the embodiment of FIG. 1 are maintained. For example, when the consonant 'a' and 'b' are placed on the same key, the first Korean input key 1 is pressed once and the 'overlap' key is pressed to form 'ㄲ'; 'ㄸ' is formed by pressing the second Hangul input key (2) having consonants 'ㄷ' and 'ㄹ' on the same key once and then pressing the 'overlap' key; Pressing the third Hangul input key (3) having consonants 'ㅁ' and 'ㅂ' on the same key once (or twice) and then pressing the 'Overlap' key forms 'ㅃ'; 'ㅆ' is formed by pressing the fourth Hangul input key 4 having consonants 'ㅅ' and 'ㅇ' arranged on the same key once and then pressing the 'overlap' key; After pressing the fifth Hangul input key (5) having consonants 'ㅈ' and 'ㅊ' on the same key once, and pressing the 'Overlap' key, 'ㅉ' is formed.

Even if the keyboard combination of FIG. 3 is applied, the key manipulation and application rules of the key combination shown in the embodiment of FIG. 1 are also maintained.

FIG. 4 is a plan view showing a fourth embodiment of the keyboard combination of the present invention, showing a difference in arrangement of consonants and vowels from FIG. 2, wherein FIG. 4 shows all consonants arranged on the left side and all the vowels on the right side. will be.

The key combination shown in the embodiment of FIG. 4 also follows the key manipulation and application rules of the key combination shown in the embodiment of FIG. 1.

Finally, the system reads the letters (syllables) by voice synthesis whenever one letter (syllable) is completed, and helps to prevent typos by checking the letters you are typing. After the document is completely closed, the user can read the entire document even when the user wants it.

Completion of syllables is executed when the following conditions are met.

A) When a consonant is input at the stage where the first neutral is to be input (forming syllables as 'consonants')

B) If a consonant is input at the stage where the second finality is to be input, but it is impossible to form a consonant consonant (the syllable is formed by 'consonant + vowel + consonant')

C) When consonants are input after forming a consonant consonant in the last input step (syllables forming 'consonant + vowel + consonant + consonant')

ㄹ) When a vowel is input at the second neutral input stage, but it is impossible to form a vowel vowel (syllable + vowel syllables, the next syllable forms an incomplete syllable)

ㅁ) When a vowel is input at the stage of inputting the first finality after the formation of the double vowel (syllable + double vowel), and the next syllable is `` vowel '' incomplete syllable

모음) When a vowel is input at the stage of entering the second bell ('Syll + Collect' to form syllables)

ㅅ) When a vowel is input after forming a consonant consonant in the last input step (consonants + consonants + consonants + consonants)

The voice output function is performed through the following process.

First, the function of generating a voice every time a syllable is completed is performed through the following process.

Recognizing that a syllable is completed, the code of the completed character is sent to the input unit, which is the first step of the speech module. The input unit sends the input code to the search unit (substituting the code value used in the voice DB if necessary) and searches it in the syllable unit voice DB. If it finds the same code, it sends it to the voice generator. The voice generator generates a voice of the corresponding code value and sends it to the output unit. At the output, voice is sent out through the speaker.

Next, a function of outputting the entire input document by voice is performed through the following process.

When the user selects the document reading function, the content of the document is sent to the speech module. First, the input unit analyzes the document in sentence units and word units, and then sends it to the phonological rule application unit. In the phonological rule application unit, the phonetic rules are applied and converted for each word unit, and the voice is generated by referring to the diphone DB and sent to the output unit. If possible, add rhyme information such as intonation and accent. At the output, voice is sent out through the speaker.

It is also within the scope of the present invention that the keyboard combination of the present invention Hangul input system is applicable to all Hangul input systems with a limited number of keys.

The effects obtained by the present invention having the configuration and operation relationship as described above are excellent in directness, can be easily understood and learned, and the input method is simple because many keys are not required for the implementation of one element. It is possible to realize fast Hangul input due to the small number of key inputs. Especially, it has a very useful effect such as improving the input speed by effectively solving the problem of recognition confusion between consonants assigned to the same key. Here, to help prevent typos by checking the letters you are typing, you can say the letters (syllables) every time a letter (syllable) is completed, or the entire document after the input is completed. The system is equipped with the ability to read synthetically.

The above is summarized in the table below.
