Description

Hangul code input device of compact keyboard {HANGUL INPUT DEVICE FOR COMPACT KEYBOARD}

The present invention relates to a Hangul code input device of a compact keyboard, and more particularly, to include a vowel / consonant primary key and an append key for inputting a vowel and a consonant, respectively, to facilitate continuous consonant input and complex vowel input. It relates to a Hangul code input device and a Hangul input method of a compact keyboard.

In order to provide Hangul transmission service using the compact Hangul keyboard with a limited number of key buttons, such as an electronic telephone keypad, the alphabet of the language to be supported is effectively duplicated on the telephone keypad or the user can operate the function key. You should be able to extract or combine the Hangul alphabet you want quickly.

Accordingly, various Hangul input systems are known to satisfy such technical needs. Representative examples of Korean Hangul code input methods using an electronic telephone keypad include Korean Patent Application Publication No. 92-005489, Republic of Korea. Patent Application Publication No. 92-008579, Republic of Korea Patent Application Publication No. 93-005413, Republic of Korea Patent Application Publication No. 96-006547, Republic of Korea Patent Application Publication No. 96-020207, Republic of Korea Patent Application Publication No. 96 -027934, Republic of Korea Patent Application Publication No. 96-043680, Republic of Korea Patent Application Publication No. 97-002558, Republic of Korea Patent Application Publication No. 97-056560, Republic of Korea Patent Application Publication No. 97-056585, Republic of Korea Patent Korean Patent Application Publication No. 97-064093, Korean Patent Application Publication No. 97-072853, Korean Patent Application No. 97-031661 Stations and the like Patent Application Publication No. 97-072848 call, the Republic of Korea Patent Application Publication No. 97-078245 call.

Korean Patent Application Publication No. 97-072848 among the published applications disclosed in this way is inconvenient to familiarize with the keyboard because the arrangement of the letter is mixed, it is necessary to input the end mark character every time the combination of one letter is completed. There is such a problem.

Meanwhile, the well-known X coordinates, XY coordinates, and continuous push Hangul input methods used in PCS phones and the like currently use a separate mode conversion button (for example, LG Cyan). The function buttons such as the left and right arrow key buttons (→, ←) should be provided separately, and the user should bear the inconvenience and burden such as the relatively high number of key button manipulations and relatively long time to read the coordinates of the keyboard. do. The Hangul code input method using the electronic telephone keypad according to the prior art enumerated above is very different from the Hangul input system provided by a general Hangul word processor, thereby degrading user friendliness.

Korean Patent Publication No. 97-002558, which treats vowels as a combination of Cheon (·), Ji (ㅡ), and phosphorus (ㅣ) Samjae, focusing on the principle of creating Hunminjeongeum among the published patent applications. The dog reverses the common sense of thinking that it is necessary and realizes a simple letter arrangement. FIG. 1 shows the keyboard arrangement shown in Patent Publication No. 97-002558.

Republic of Korea Patent Application Publication No. 97-002558 No. A Korean input device is proposed that calculates short vowel and double vowel codes by assigning unique codes by assigning vowel strokes (.), Ji (ㅡ), and phosphorus (ㅣ) to each of three keys. However, Korean Patent Application Publication No. 97-002558 utilizes a very good vowel discipleship principle, whereas two or more consonants are collected into a transition family and assigned to one key to generate consonants through different key operations. Because it is a method, when assigning multiple consonants to one key button, even if you use a key sequence structure with even regularity, it takes a lot of effort to be aware of it, and it is necessary to press many keys to enter a complex vowel. There is this.

Therefore, the present invention is to solve the above problems, by providing a vowel in a completed form, the selection of a complex vowel is possible with a small number of key inputs, one button can be used as an input key of consonants and vowels This paper presents a Hangul code input device for a compact keyboard that enhances number Hangul matching.

The above object of the present invention is a compact Korean keyboard and a plurality of vowels composed of a plurality of vowel / consonant basic keys that can be selectively operated as a consonant key or a vowel key and an append key that is operated by one vowel input key.

A consonant and vowel input method according to the present invention will be described with reference to FIG. 3. In FIG. 3, a key corresponding to the numeric key “0” will be referred to as an append key. In addition, prior to the description, the consonant is "ㄱ, ㄴ, ㄹ, ㅁ, ㅂ, ㅅ, ㅇ, ㅋ, ㅋ, ㅌ, ,, ㅎ" as a basic consonant, ㄲ, ㄸ, ㅆ, ㅃ, ㅆ , ㅉ "is defined as a double consonant consisting of two different basic consonants, such as" ㄻ, ㄺ, ㅄ, ... ", which enters the final consonant, and the vowel is defined as" ㅏ, ㅑ, ㅓ, 기본, ㅗ, ㅛ, TT, ㅠ, ㅡ, ㅣ "is the basic vowel," ㅐ, ㅒ, ㅔ, ㅖ, ㅟ, ㅚ "is the vowel and" ㅘ, ㅙ, ㅝ, ㅞ "is defined as the double vowel Let's do it. 3 is a keyboard structure according to an embodiment of the present invention, various embodiments are possible, such as changing positions of consonants and consonants, or changing positions of vowels and vowels. For example, in the arrangement of FIG. 3, when a letter such as "of" is made, it is inconvenient to press a key corresponding to the number "8" and a key corresponding to the number "0". Therefore, in order to solve this problem, it is preferable to replace the vowel "ㅠ" assigned to the numeric key "2" and the vowel "-" assigned to the numeric key "8".

1. Consonant input

1) Input basic consonant written on keyboard

As shown in FIG. 3, the consonants shown in Table 1 are assigned to each keyboard corresponding to the numbers 1 to 9. FIG. The basic consonants assigned to the right side of Table 1 can be entered with a single key touch.

Numeric keys Assigned default consonant One A 2 ㅈ 3 ㅇ 4 ㅂ 5 ㅍ 6 N 7 S 8 ㅎ 9 C

2) Input basic consonants not assigned to keyboard

The basic consonants not assigned to the numeric keys of FIG. 3 can be selected using 1) another basic consonant or 2) an append key while pressing the basic consonants. Table 2 shows the key buttons of FIG. 3 that must be entered in order to enter basic consonants not assigned to the keyboard.

4) Double consonant input

Heavy consonants such as "ㄺ, ㄻ, ㅄ, ...." can be selected by pressing another basic consonant while holding the basic consonant. Table 4 shows the key buttons of Fig. 3 for inputting several double consonants.

A double consonant Key button to enter ㄳ A (*) + ㅅ ㄺ A (*) + c (*) + a ㄻ A (*) + c (*) + a (*) + b ㄼ A (*) + c (*) + ㅂ ㄽ A (*) + c (*) + ㅅ ㄾ A (*) + c (*) + a (*) + append ㄿ A (*) + c (*) + ㅀ ㄱ (*) + ㄷ (*) + ㅎ ㅄ ㅂ (*) + ㅅ ㄵ ㄴ (*) + ㄶ ㄴ (*) + ㅎ

(*) Indicates that the corresponding key is pressed, and as shown in Table 4, in order to input "ㄺ" as the finality, press "c" while pressing "a" and "c" Hold down and press "a" to complete. As another example, inputting "ㄵ" indicates that you should enter "ㅈ" while holding down "b".

As described above, the consonant input according to the present invention is characterized in that the basic consonant written on the keyboard, the basic consonant not marked on the keyboard, the middle consonant or the double consonant inputs at least one consonant button until it is released. It is completed by the action. That is, 1) the basic consonants written on the keyboard can be input by one key touch, and 2) basic consonants not written on the keyboard are completed by pressing the addition key or another basic consonant while pressing the basic consonants written on the keyboard. do. 3) In the case of middle consonants, use the append key once or twice while pressing the basic consonants. 4) In the case of double consonants consisting of two basic consonants, at least until completion, as shown in Table 4. You can see that one of the basic consonants needs to be pressed.

Next, the input of the vowel according to the present invention will be described.

2. Enter a collection

1) Basic Collection Input

As shown in FIG. 3, each basic vowel shown in Table 5 is assigned to each keyboard corresponding to the numbers 1 to 9. The default vowels assigned to the right side of Table 5 can be entered with a single key touch.

Numeric keys Assigned default consonant One ㅗ 2 ㅠ 3 ㅏ 4 ㅛ 5 ㅓ 6 ㅑ 7 TT 8 ㅡ 9 ㅕ 0 ㅣ

2) Enter the append bar

The addition bar of "의, ㅒ, ㅔ, ㅖ, 하였다, ㅚ" can be selected by holding down the main bar and pressing the add key. Table 6 shows the key buttons of FIG. 3 for entering an append vowel.

Addition collection Key button to enter ㅐ ㅏ (*) + append key ㅒ ㅑ (*) + append key ㅔ ㅓ (*) + append key ㅖ ㅕ (*) + append key ㅟ TT (*) + add key ㅚ ㅗ (*) + append key

As shown in Table 6, "ㅐ" is completed by pressing the append key corresponding to the number "0" and the default "" "while holding down the default collection" ㅏ ". As another example, when inputting "ㅟ", it is completed by inputting the addition key corresponding to the number "0" and the basic collection "ㅣ" while pressing "TT".

3) Double vowel input

The double vowel of "ㅘ, ㅙ, ㅝ, ㅞ" can be selected by holding down the main vowel and pressing the main vowel or the add key. Table 7 shows the key buttons of Fig. 3 for inputting a double vowel.

Double vowels Key button to enter ㅘ * (*) + ㅏ ㅙ ㅗ (*) + ㅏ (*) + append key ㅝ TT (*) + ㅓ ㅞ TT (*) + ㅓ (*) + Add key

As shown in Table 7, " ㅘ " is completed by pressing the main bar " ㅏ " As another example, entering "ㅞ" is completed by pressing "ㅓ" while pressing "TT", releasing "TT" and pressing the append key without removing "ㅓ".

3. Description of Autocomplete Rules

As described above, a feature of the present invention is that vowels and consonants can be simultaneously assigned to one key and processed. For example, the number "1" is assigned "a" and "ㅗ" to one key. The problem with assigning vowels and consonants to a key is to distinguish when consonants are assigned and when vowels are assigned.

This will be described with an example of inputting "none". "None" should be entered in order "oh, ㅓ, ㅂ, ㅅ, ㅏ,,", the case of the keyboard shown in Figure 3 will be described using Table 8.

The number to be entered ㅇ ㅓ ㅂ S C ㅏ Corresponding numbers in the keyboard of Figure 3 3 5 4 7 9 3 Rule / vowels assigned to the keyboard of FIG. ㅇㅏ ㅓ ㅂ ㅛ ㅅㅜ ㄷ ㅕ ㅇㅏ

Hangul syllables consist of "consonant (consonant) + neutral (vowel) + species (consonant)" like "no" "(in this case," ㅇ "is treated as a consonant rather than a vowel) or" It is composed of "consonant (consonant) + neutral (collection)" as ". In the present invention, the character is completed by the auto-completion rule. As shown in Table 8, in order to input "no", the numeric keys "3, 5, 4, 7, 9, 3 of the keyboard shown in FIG. "Must be pressed consecutively. In this case, up to "3, 5" is recognized as displaying "uh" without any problem of interpretation. However, in the case of the next two buttons "4, 7", the user wants to input a double consonant "ㅄ (consonant + consonant)", but it can be interpreted as "negative (consonant + vowel)" depending on the interpretation. Accordingly, in order to simultaneously assign consonants and vowels to one key, the consonants are completed in a state in which at least one button is not dropped when inputting a double consonant which is a continuous consonant as in the present invention. The input method according to the invention is shown in Table 9.

The number to be entered ㅇ ㅓ ㅂ S C ㅏ Corresponding numbers in the keyboard of Figure 3 3 5 4 7 9 3 Pressing method according to the invention 3 5 4(*) 7 9 3

That is, in inputting the double consonant "ㅄ", by pressing the key "4" corresponding to "ㅂ" while pressing "s", it is indicated that the successive keys represent the double consonants. The same applies to the addition vowels and double vowels, which consist of consecutive basic vowels.

In the Hangul input method according to the present invention, a problem that may occur when the auto-completion rule is followed may occur when the next syllable is input when the previous syllable is configured as "first + neutral". For example, the case of entering the word "skip" will be described using Table 10.

Input ㄸ ㅟ ㅇ ㅓ A ㅏ ㅂ N ㅣ C ㅏ Input Button 9 (*) + 0 + 0 7 (*) + 0 3 5 One 3 4 6 0 9 3 Typing error ㄸ ㅟ ㅇ ㅓ A ㅇ ㅛ N ㅣ C ㅏ

In other words, when the user inputs "Jumping", the "~ Urpa ~" part may be interpreted as "Jumping" because an input error occurs as "~ Ultra ~". This problem occurs when the previous syllable is composed of "primary + neutral" and there are subsequent syllables. In the present invention, in order to solve the problem, the first syllable "first + neutral" is inputted. After pressing the add key, which is the delimiter, the syllable input is divided and the next syllable is input. Table 11 shows the key input of the present invention to input using a delimiter.

Input ㄸ ㅟ ㅇ ㅓ Separator A ㅏ ㅂ N ㅣ Separator C ㅏ Input Button 9 (*) + 0 + 0 7 (*) + 0 3 5 0 One 3 4 6 0 0 9 3

Therefore, according to the Hangul input method of the present invention, Hangul input is possible using only the numeric keys 0 to 9. Of course, the "#" or "*" button may be used to replace the delimiter. Of course, if possible, it is preferable to enable Korean input using only the numeric keys 0 to 9.

This allows you to match Korean words to phone numbers or phone numbers to Hangul. Using these matching functions, you can easily generate a phone number. If you match a specific product or company name to a phone number and use it in your ad, There are advantages to remembering phone numbers.

In the case of the input phrases shown in Table 11, the case of "~ i" does not have to be interpreted as "~ ni + c (final) + o", even if there are consecutive syllables with "consonant + neutral". will be. The word "Nit" does not exist in Korean grammar, so it is possible to recognize "c" as the beginning of the next letter without judging it as a finality. However, in order to give regularity to the user of the compact keyboard, as shown in Table 11, when inputting "Nida", "Ni + Separator + Da" can be input.

4 is a block diagram illustrating a detailed configuration of a control unit and a key boarder of the compact type keyboard input device. The consonants input from the compact key board 70 are combined in the consonant combination unit 11. Consonants can be input by one key operation in the case of the basic consonants indicated on the board as described above, but additional key operations such as adding keys after storing the basic consonants, middle consonants and double consonants not indicated on the board temporarily on the stack It is completed by one consonant and then delivered to the syllable coupling unit (18).

The vowels input from the compact key board 70 are combined in the vowel combining unit 15. In the case of vowels, like the consonants, the basic vowel can be entered by one key operation, but in the case of vowels or double vowels, the vowels or double vowels are temporarily stored on the stack and then added to one vowel by additional key operations such as the append key. After completion, it is transmitted to the syllable coupling unit 18.

The syllable combining unit 18 serves to combine the consonants and vowels input from the consonant combination unit 11 and the vowel combination unit 15, and stores the syllables input so far in the stack. Therefore, when the user selects "Erase", the syllable stored in the stack can be erased one by one.

5 shows a processing flow in which a key input is processed according to the present invention. If you select Hangul input mode, you will receive first consonants first. At the time of inputting the initial consonant, the compact keyboard operates as a consonant input key. Completion of the initial input is judged as the time when any one of the keys of the compact key board is not pressed as described above. The initial input is completed and the neutral input is processed. When the neutral is input, the compact keyboard operates as a vowel input key. As described above, the time point at which the neutral input is completed may be determined as the time point at which any one of the keys of the compact key boarder is not pressed.

When the neutral input is completed, it is determined whether the separator is input. When the delimiter is input, it is determined that the syllable to be input is composed of "first + neutral", and the syllables are combined. If the delimiter is not input, it is determined that the syllable to be input is composed of "first + neutral + finality", and the finality is received. At this time, the compact key board operates as a consonant input key. The final input is completed, there is no input of the next syllable, and the syllable combination is completed and finished. If there are other syllables to be input, the above input process is repeated.

Comparative example:

The method shown in Korean Patent Publication No. 97-002558 and the method of the present invention will be compared with Table 12 using several examples.

Input Hits of No. 97-2558 (Cheonjiin) The number of strokes according to the invention There was not 19th 15th Why are you here 18th 12th I'm calling 21 14th

As shown in the above table, the input method according to the present invention shows that the same phrase can be input in much fewer strokes when compared to the currently commercialized Cheonjiin. In entering the sentence “Why?” Which is a sentence containing a specific double vowel, the method according to the invention can be input in much less strokes.

Hangul input method of the present invention can be applied to the touch pad Hangul input method using a hand in a PDA as well as a mobile phone terminal. In conventional PDA, Korean input includes handwriting recognition using stylus and stylus input through computer keyboard. However, if you don't have a stylus, you won't be able to enter your handwritten handwriting. When typing Hangul into a PDA by hand, the keyboard layout must be large, but the PDA screen is small and cannot be made large enough to be clicked by hand. In this case, using the input method proposed in the present invention, since only one button can be made larger, a single button can be made larger.

Since consonants and vowels can be assigned to one key at the same time, it is possible to input vowels with much fewer strokes than conventional methods. That is, consonants and vowels are assigned to one button, so that the user can make a selection based on the Hangul input rule without a new method for selecting consonants and vowels, thereby reducing the number of button presses.

To solve the problem of judging whether a consonant and a vowel are assigned to one key, to keep the consonant or vowel separated without using a separate key to distinguish between a double consonant or a double vowel By allowing input from, the distinction between double consonant or double vowel input is made clear.

Consonants and vowels are assigned to a single button, so Hangul words ----> phone number, phone number ---> Hangul compatibility is good, even using a compact number, it is possible to advertise using a phone number. For example, by matching with "Samsung" ----> "731-6753", it is possible to easily memorize the phone number by matching the phone number with Korean words. It became possible.
