Abstract

PURPOSE: A Hangul input system using the number plates of a portable phone and a telephone is provided to systematically connect the arrangement of a Hangul keyboard, the state transition of consonants and vowels, and the input of characters not displayed on the key board so that a user can input letters rapidly and easily. CONSTITUTION: The basic consonants and vowels of Hangul and function keys are arranged on the number plates of a portable phone and a telephone. A user inputs a letter not arranged on the key board by pushing a shift key and changing a previously inputted letter. While consonants and vowels are inputted alternately, consonants or vowels can continuously be inputted according to the user's selection. The basic consonants(giyeok,nieun,digeuk,rieul,mieum,bieub,siok,iueng,jieuk) and the basic vowels(o,a,ai,u,eo,ei,eu,i,yeo) are doubly arranged on the telephone number plates. On the key board, function keys, such as *, 0, #, Korean/English, shift, consonant/vowel, etc., are arranged.

Description

Korean character input system using the keypad of telephone and cellular phone}

The present invention relates to a number plate of a telephone and a text input system using the same. In the case of inputting Korean and English using only numeric keypads such as a telephone or a mobile phone, various methods using a combination of several numbers are used to input many characters with only a limited button. In particular, Hangul input is more complicated because there is a distinction between consonants and vowels, and there is a distinction between consonant-neutral-jongjong. The prior art in this field includes a method of arranging consonants and vowels in one keyboard and dividing the consonants and vowels into two keyboard layouts and selecting a keyboard by switching input states. The method of arranging consonants and vowels in one keyboard has the advantage that syllable boundaries are automatically recognized without the need for consonant-vowel conversion. However, the disadvantage is that the number of inputs is large and it is difficult to remember the arrangement of consonants. On the other hand, the method of using consonant and vowel keyboard separately has the disadvantage that it is very inconvenient to use because the syllable recognition is not automatically performed and the consonant-vowel conversion is forced. In the present invention, the consonant and vowel keyboards are used separately, but the consonant-vowel conversion is made as intuitive as possible to reduce the existing disadvantages as much as possible, and the arrangement of the consonant and vowel keyboard layouts is easily memorized. Saved as much as possible.

The technical problem to be achieved by the present invention is a Hangul input method that is easy to use and fast input speed by systematically connecting the arrangement of the Hangul keyboard, the state switching of consonants and vowels, and the input of characters not displayed on the keyboard in inputting Hangul with numeric keys only. Is to implement

With regard to keyboard layout, the purpose is to display the most commonly used letters on the keyboard as basic letters and to make the order of the layout intuitively understandable to anyone.

Regarding the state transition of consonants and vowels, a method of switching by the user as much as possible and automatically switching is used, and the purpose of the user is to provide consistency in the state transition using the function keys.

Regarding the method of inputting the letters that do not appear in the basic keyboard, the purpose of the present invention is to provide consistency in the method of inputting the characters so that the user can easily enter the undisplayed characters only by viewing the basic keyboard.

In all cases, there should be no errors or disagreements in how to interpret the pressed key, and the purpose of the parts of the Hangul input method is to harmonize with the whole system.

<Default keyboard layout for Korean consonants and vowels>

The character keyboard of the present invention has an arrangement of Korean consonants and vowels as shown in Figs.

3 shows a basic consonant of a Korean alphabet above a number, and a correspondence relation between a consonant and a number key is as follows.

(1,2,3,4,5,6,7,8,9) → (ㄱ, ㄴ, ㄹ, ㅁ, ㅁ, ㅅ, ㅇ, ㅈ)

4 shows the basic vowels of Korean characters over numbers. The correspondence of vowels to numeric keys is as follows.

(1,2,3,4,5,6,7,8,9) → (ㅗ, ㅏ, ㅐ, TT, ㅓ, ㅔ, ㅡ, ㅣ, ㅕ)

Here 'ㅕ' is not the basic vowel, but the remaining number '9' corresponds to the most frequent vowel among the double vowels.

<Function Key Settings>

The keys (*, 0, #) correspond to the function keys (Korean / English, shift, parent / child).

The Hangul / English conversion key cycles through the Hangul / English / Number / Symbol input mode.

The 'shift' key is used to enter consonants and vowels that are not present in the default keyboard.

The 'child / parent' conversion key is used to coerce the consonant and vowel input states.

<Enter characters not in default keyboard>

Since the basic keyboard shown in FIGS. 3 and 4 has no consonant sounds and old sounds, vowel legend double vowels, and the like, the user presses a basic letter and then presses the 'shift' key to change a letter already input to another letter associated with the letter. It was made.

Consonant Circulation: Pressing the 'shift' key converts the already entered basic consonant into a rough sound, and pressing it once again changes to the old consonant consonant. Each press of the 'shift' key cycles through the basic consonants → rough consonants → old consonants → basic consonants. Table 1 below shows specific input methods.

Input of consonant and consonant consonants Basic consonants A loud consonant Consonant Circular example One A 10 Lol 100 ㄲ ㄱ → ㅋ → ㄲ → ㄱ 2 N 20 200 N 3 C 30 ㅌ 300 ㄸ ㄷ → ㅌ → ㄸ → ㄷ 4 D 40 400 D 5 M 50 500 M 6 ㅂ 60 ㅍ 600 ㅃ ㅂ → ㅍ → ㅃ → ㅂ 7 S 70 ㅆ 700 ㅆ ㅅ → ㅆ → ㅆ → ㅅ 8 ㅇ 80 ㅎ 800 ㅇ → ㅎ → ㅇ 9 ㅈ 90 H 900 ㅉ ㅈ → ㅊ → ㅉ → ㅈ

The basic consonants 'b', 'ㄹ', 'ㅁ', etc. without corresponding consonant and consonant consonants do not change the input state even when the 'shift' key is pressed.

In the case of the basic consonant 'ㅅ', there is no harsh sound, but for convenience, 'ㅆ' is assigned to '70'. Therefore, pressing 'shift' once is 'ㅆ', and pressing twice is 'ㅆ'. Press 'shift' again to return to 'ㅅ'. Therefore, 'ㅅ' → 'ㅆ' → 'ㅆ' → 'ㅅ'.

The arrangement of 'ㅎ' is difficult to see phonologically as harsh, but it was seen as harsh to handle consistently using the given number. In this case, there is no consonant sound, so circulate as 'ㅇ' → 'ㅎ' → 'ㅇ'.

Vowel Circulation: Pressing the 'shift' key changes the default vowel entered into a legendary double vowel. Each time you press the 'shift' key, the cycle changes from the default vowel to the legendary vowel and back to the default vowel. Table 2 below shows specific input methods.

Legend input double vowel Basic collection Legendary vowels Circular example One ㅗ 10 ㅛ ㅗ → ㅛ → ㅗ 2 ㅏ 20 ㅑ ㅏ → ㅑ → ㅏ 3 ㅐ 30 ㅒ ㅐ → ㅒ → ㅐ 4 TT 40 ㅠ TT → ㅠ → TT 5 ㅓ 50 ㅕ ㅓ → ㅕ → ㅓ 6 ㅔ 60 ㅖ ㅔ → ㅖ → ㅔ 7 ㅡ 70 ㅡ 8 ㅣ 80 ㅣ 9 ㅕ 90 ㅕ

The basic vowels 'ㅡ', 'ㅣ', 'ㅕ', etc., without corresponding legendary double vowels, do not change the input state even when the 'shift' key is pressed.

<Input of consonants and vowels>

Basically, the consonant and the vowels are represented by successively inputting two consonants and two vowels that constitute the consonant and the vowels, respectively. At this time, the 'child / mo' conversion key must be between consonant and consonant or vowel and vowel. Table 5 below shows how to input the vowel and vowel consonants.

Input method of vowel consonants and vowels Lucky consonants Double Vowels ㄳ 1 # 7 ㅘ 1 # 2 ㄵ 2 # 9 ㅙ 1 # 3 ㄶ 2 # 80 ㅚ 1 # 8 ㄺ 4 # 1 ㅝ 4 # 5 ㄻ 4 # 5 ㅞ 4 # 6 ㄼ 4 # 6 ㅟ 4 # 8 ㄽ 5 # 7 ㅢ 7 # 8 ㄾ 4 # 30 ㄿ 4 # 60 ㅀ 4 # 80 ㅄ 6 # 7

Consonant / Voice Conversion

By default, consonant / vowel conversion is done automatically, after vowels are recognized as vowels and after vowels as consonants. However, in the case of a compound consonant, a compound vowel, and a final-choson, a coercion is required, so the 'child / mo' conversion key is used.

Table 4 shows an example of inputting only consonant / vowel automatic conversion.

order condition input function Change of state result One 0J One A 0J → JM A 2 JM 3 ㅐ JM → MJ dog 3 MJ One A MJ → JM Guest 4 JM 4 TT JM → MJ Opening 5 MJ 4 D MJ → JM Dig 6 JM 8 ㅣ JM → MJ frog

Table 5 shows an example of input when there is a consonant / vowel forced conversion between the first and the first.

order condition input function Change of state result One 0J 5 M 0J → JM M 2 JM One ㅗ JM → MJ mother 3 MJ One A MJ → JM neck 4 JM # 'Child / parent' JM → 0J neck 5 0J 7 S 0J → JM share 6 JM One ㅗ JM → MJ Mokso 7 MJ 4 D MJ → JM Neck brush 8 JM 8 ㅣ JM → MJ voice

Table 6 shows an example of double vowel input using consonant / vowel coercion.

Table 7 shows examples of double consonant input using consonant / vowel coercion.

order condition input function Change of state result One 0J 8 ㅇ 0J → JM ㅇ 2 JM 5 ㅓ JM → MJ uh 3 MJ 6 ㅂ MJ → JM work 4 JM # 'Child / parent' JM → 0J work 5 0J 7 S 0J → JM No 6 JM # 'Child / parent' JM → 0J No 7 0J 3 C 0J → JM None 8 JM 2 ㅏ JM → MJ none

<Syllable boundary recognition>

The syllable boundary is automatically recognized because it basically uses the 2-Bul Hangul input method automata. Therefore, you can just enter the phonemes consecutively. However, it is only necessary to input the 'za / mo' conversion key between consonants or vowels.

The next letter after the consonant is viewed as a vowel, and the next letter after the vowel is viewed as a consonant. Therefore, when consonants come after consonants and when vowels come after vowels, you need information to specify them. This is the role of the 'child / parent' conversion key.

Consonants come in succession when the consonant and the final consonants are input. Therefore, only three of these cases, such as Bokja consonant, Bokcho consonant, and Jong-seong-cho, need to enter the 'character / mo' conversion key between letters.

<Enter spaces>

Even though most inputs are made in Korean, a lot of spaces are used for contents inputted from a mobile phone. Therefore, you need an easy way to enter whitespace. In the present invention, when a space character is to be input, the space is inputted by pressing the 'shift' key after pressing the 'child / mo' conversion key regardless of the state.

Ex) Nice to meet you

522 # 2275 # 0622 # 126 # 776 # 2832

<English / English / Number / Symbol Switch>

Press the 'Korean / English' key to switch between Korean, English, numbers and symbols. At this time, the input method of English, numbers, symbols is not the scope of the present invention. However, 'English / English' conversion key is input mode conversion key and '*' character should not be input even in English, numbers and symbols.

Ex) I read three books

9031 # 874 # 0 ** 3 ** 14 # 52 # 0884 # 1 # 8570 # 32

Finally, Table 8 shows Hangul display and state conversion according to the input of each state in FIG.

Status input 0J JM 0M MJ One A, goto JM Go, goto MJ Go, goto JM A, goto MJ 2 B, goto JM Go, goto MJ Go, goto JM B, goto MJ 3 C, goto JM Go, goto MJ Go, goto JM C, goto MJ 4 ㄹ, goto JM TT, goto MJ TT, goto JM ㄹ, goto MJ 5 ㅁ, goto JM Go, goto MJ Go, goto JM ㅁ, goto MJ 6 Go, goto JM Go, goto MJ Go, goto JM Go, goto MJ 7 Goto JM ㅡ, goto MJ ㅡ, goto JM ㅅ, goto MJ 8 ㅇ, goto JM ㅣ, goto MJ ㅣ, goto JM ㅇ, goto MJ 9 Goto JM Go, goto MJ Go, goto JM Goto MJ * Hanyoung Conversion Hanyoung Conversion Hanyoung Conversion Hanyoung Conversion 0 Blank Change the type of consonants already input Blank, goto 0J Change the type of a collection already entered # goto 0M goto 0J goto 0J goto 0M

Hangul keyboard using the numeric keys of the present invention is a simple arrangement that anyone who knows the Hangul can be memorized once, so it is easy to input Hangul even when there is no Hangul keyboard such as a general telephone or an electronic calculator. In addition, using the automatic conversion of consonant and vowel input modes, the key pressed for entering one syllable is 3.15 times on average. Therefore, it is possible not only to use a built-in Hangul input device like a mobile phone but also to input information through a general phone.
