Abstract

According to the present invention, a terminal for inputting a character by manipulation of a key capable of displaying one or more numbers, consonants or vowels has a basic character input rule capable of inputting a character corresponding to the manipulation of a key, and the basic character input rule. Apart from the database provided in the terminal, a key value input by pressing a key indicates a character or a string generated according to the basic character input rule. The words, phrases or sentence data previously stored in the database are displayed on the screen separately from the characters or strings generated according to the basic character input rule, and the characters and phrases generated and displayed according to the basic character input rule are displayed. Alternatively, by selecting and inputting any one of sentence data, a data input mode using the database and a text input mode for inputting characters not in the database are integrated into one.

Description

Key input method

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a key input method, wherein a key input allows a user to easily input keys of a terminal such as a mobile phone, a work analysis program phone, a personal digital assistant, a web pad, and the like. It is about a method.

With the development of communication technology, terminals such as mobile phones, WAP phones, PDAs, web pads, etc. have become popular, and their functions are also changing in various ways. That is, the trend is to add a function such as Internet search or transmission of various information beyond simple communication function.

Accordingly, in the conventional terminal, as illustrated in FIG. 1, a key value of one or more alphabets is given to one key 12 so that a large number of alphabets can be input by a keypad 10 having a limited number for inputting various information. I adopt the method.

In case of inputting the word 'how' in the conventional multi-tap method using this, press '4' twice to press 'h' and '6' three times to press 'o' and '9' once to enter 'w' do. That is, input is performed in one alphabetical unit.

In addition, when entering the word 'how' as the order of the array order, press '4' and '2' to press 'h', '6' and '3' to press 'o', '9' and '1' Press' to enter 'w'.

In addition, in the case of the character input method "T9 (www.t9.com)" developed by "Tegic communications Inc. (www.Tegic.com)", if you want to input 'how' using the word database, FIG. If you press '4', '6', '9' key once, 'g, h, i' assigned to '4', 'm, n, o' and '6' , All words consisting of 'w, x, y, z' assigned to '9' are searched from the database and displayed on the LCD. Then, the user inputs the word by selecting a desired word from the displayed words.

In the case of "EZtext" of "Zi Corp.", the word prediction function is added to the method of "T9" so that a word having a code value including the word value can be displayed even if only a part of the word code is input.

In the case of "T9", input is easier than in multi-tap mode, but since only word data is used, in case of code value of "4663", one of 'good, gone, home, hood, hoof, hone, goof' is applied. The word corresponding to the code is often duplicated, and if the word to be input is not present in the data, it is inconvenient to switch to the multi-tap mode and to return to the "T9" mode again.

"Zi Corp." The same is true.

An object of the present invention for solving such a conventional problem, a sentence or phrase with a minimum key operation when inputting a word or sentence by operating keys of various terminals such as a mobile phone, a WAP phone, a PDA, a web pad, etc. Another method is to provide a key input method for inputting a word.

In the key input method of the present invention for solving the above object, in the key input method of the terminal for inputting a character by operation of a key that can display one or more numbers, consonants or vowels, the terminal corresponds to the operation of the key In addition to having a basic character input rule capable of inputting a character, the key value input by pressing a key is generated according to the basic character input rule through a database provided in the terminal separately from the basic character input rule. In addition to displaying characters or character strings, word, phrase or sentence data previously stored in the database is displayed on the screen separately from the character or character string generated in accordance with the basic character input rule, and according to the basic character input rule. Select and input any one of the generated text, phrase or sentence data Thus, the data input mode using the database and the text input mode for inputting characters not in the database are integrated into one.

In the basic character input rule, when selecting a phoneme arranged in a key, the first phone may be input by pressing a corresponding key, and the second phone may be input by using a corresponding key and a '*' key.

The database used for the terminal includes a sentence database, a phrase database, and a word database, which can be optionally used.

In this case, the sentence database has a sentence data code generated by pressing a key value on which the first phoneme of words constituting the sentence is written once, and the sentence database is used together with a word database, wherein the input method is a word structure. It consists of one keystroke per phone.

The sentence database may include a proper noun and a pronoun, which are not words that can be databased due to the characteristics of the sentence, when the sentence is inputted by a combination of keys corresponding to the first phoneme of each word constituting the sentence. In the case of a sentence having a pattern, a word code of a part that cannot be converted into data can be inputted as '*' to select the sentence, and a word replaced by '*' can be re-entered.

The phrase database includes phrase data consisting of two or more words. The phrase data input includes a method of inputting a phoneme corresponding to an initial letter of each word, and inputting each phoneme constituting a phrase ignoring spacing. Either of the methods to make it possible can be applied selectively or both methods.

In addition to the language used for the terminal, an additional language database of one or more other languages is used in the same input mode, and the additional language database includes a sentence database, a phrase database, and a word database; Enables the use of one or more databases selectively, and allows the user to select the intended character string without changing the input mode by simultaneously matching the additional key data with the basic language data to the input key value. It is possible to input two or more languages in one input mode without using.

In the text input mode, the phone number or e-mail address of the other party to which the message is to be sent is input to the terminal in advance so that the vocabulary of the database may be separately applied according to the phone number or the e-mail address.

You can also reduce the amount of data duplicated in the same code by varying the database over time and date.

In other words, during holidays such as Christmas or New Year, a message of congratulation or health is usually sent. These greetings are often used only for that date, so they will not be searched if they remain in the database for other periods.

Hereinafter, the present invention will be described in detail.

In the case of the commonly used Short Message Service (SMS), the main uses are time appointments, greetings, greetings, thankfulness, location, and love conversations. This is mainstream.

Therefore, short messages that can be used in mobile phones, PDAs, etc. are quite extensive, but the actual sentences and words can be said to be somewhat limited in frequency.

The present invention uses the above points to dataize frequently used sentences such as 'Where are you now?', 'When is it over?', 'I love you' and press the number key corresponding to the first phoneme of each word constituting the sentence. As a result, the sentence data corresponding to the key value can be written.

In this case, all data can be further edited according to the user's intention.

As the database 20 for this purpose, as shown in Figure 2, the sentence data 22, the phrase data 24 consisting of two or more words, the word data 26, the numeric data 28, foreign language data 30 Use one or more of them selectively to match them with characters or strings generated according to the key values entered.

The user inputs a string intended by the user from among the data displayed on the screen corresponding to the key value entered in each database. The priority of the duplicated data is frequency or alphabetical order or by type of data (sentence, word, And then finally entered by the operation of the select key.

Words that are not in the data can also be entered using '*', which is a subordinate letter input key, without changing the input mode. Therefore, input of general characters and data using data can be performed simultaneously in one input mode.

Of course, it is also possible to use a multi-tap method for inputting a character not present in the data and to simultaneously match data with the input key value.

Of course, a sentence, a phrase consisting of two or more words, or a word that is not in the data can be stored as data when the word is input so that it can be used as data for later input.

The present invention can be used in most languages including enumerated languages such as English and spatial languages such as Korean.

In the present invention, since two language data may be simultaneously corresponded in one input mode, two or more languages may be described together. However, embodiments of the description are divided into English input and Korean input. Simultaneous input of English and Korean Write in Japanese and Chinese.

The present invention is described on the basis of 10 numeric keypads used in general telephone terminals, but it can be used in PDAs, etc., which can use 10 or more buttons, and its use is also repeated using a computer keyboard as well as a short message. Of course, this also applies to writing.

From the user's point of view, at first, it is not possible to know what sentences or phrases are present in the database when inputting characters according to the present invention. Therefore, by adding the data notification function, when the user inputs a string included in the database as a general input, it has a function of notifying that the string is in the database.

In this case, the user can know what kind of data is in the database through a character input of a certain period.

Naturally, even if only a part of the key value is input, data including the corresponding key value may be displayed.

1. English input

In the case of the English input method, description will be made based on the button arrangement of FIG.

A sentence database 22 and a word database 26 are optionally used, and a phrase database 24 composed of two or more words can also be used.

Characters generated with an input rule according to the input key value, and sentences, phrases, and word data simultaneously displayed corresponding to the input key value may be selected by the user. The input rule that can input characters separately from the data can be any method including a multi-tap method, but here, the method of using '*' as a subordinate key is described as an example.

Referring to FIG. 1, when a word is input, 'a' has a value of '2', 'b' has a value of '2 *', and 'c' has a value of '2 **', and so on with other buttons. To capitalize, press and hold the corresponding key. For 'B', press and hold '2' and press '*' (a-AB), or press '2' and press and hold '*' (ab-B).

For example, the meaning of the input value '459' can be divided into two meanings: the first word begins with one of 'ghi', the second word begins with one of 'jkl', and the third word uses' wxyz 'means a sentence consisting of three words or more beginning with one of' wxyz '. The first alphabet is one of 'ghi', the second one is 'jkl', and the third one is a word composed of three alphabets or more, one of 'wxyz', or 'gjw'.

That is, the text and word data corresponding to the character string and the key value generated as the key value are displayed together and the user selects the character string or data. Hereinafter, with reference to FIG. 3, it demonstrates in detail.

Of course, if there is superior data in the frequency used among two or more data corresponding to one input code, it can of course correspond to it first. The input code value '459' corresponds to a sentence of 'I love you'. However, no word in the dictionary has a code value of '459'.

In order to input the sentence "I love you", the user selects a sentence database (S2) (S4), and inputs a key corresponding to the first letter 'I, l, y' of the words constituting the word I love you. When the key value '459' is pressed by pressing once (S6), the front letter 'gjw' of the '459' button is displayed one letter every time the key value is input (S8), and the key value is displayed. Check whether there are a plurality (S10). In this case, if a plurality of sentences corresponds to one input key value, the frequency of use is checked (S12) so that the frequency is displayed in ascending order or alphabetically (S14).

At this time, 'I love you', that is, sentence data corresponding to the input key value is displayed at the bottom of the screen (S14), and the user selects his intended 'I love you' (S16). If the data needs to be edited (S18), the selected data may be edited, and the data may be edited and used in an appropriate form according to the situation of use (S20).

Preferably, the data added and edited as described above can be stored selectively by the user (S22) (S24).

The word having a code value of '459' means that the first alphabet is one of 'ghi', the second one is 'jkl' and the third one is 'wxyz', as mentioned above based on the button arrangement of FIG. Means a three-letter word.

As another example, when the key value '46' is input, the letters 'gm' are displayed on the screen 40 and 'Hi mom!' And 'go' correspond together.

First, 'Hi mom!' Is a sentence consisting of two words. The first word starts with one of 'ghi' and the second starts with 'mno'. And, 'go' is a word consisting of two alphabets, the first alphabet is one of 'ghi', the second is one of 'mno'. In this case, the user may select and input a sentence or word intended by the user from the corresponding data.

Of course, if there is corresponding word data, the data may be displayed in priority.

In other words, the word 'gm' is not used in the code of '46', so 'go' is displayed first instead of 'gm' and 'Hi mom!' May appear at the bottom of the screen. In the case of 'Hi mom!', The phrase database 24 may be used to input '44666', which is a key value of each alphabet.

It is desirable to allow the user to add sentence data and word data. For words that are not in the database, it is possible to reduce the duplication of the code value of the data by inputting the '*' key, which is a subordinate designation key.

The present invention is characterized in that input methods having different input methods such as sentence generation rule, sentence database 22, phrase database 24, and word database 26 are processed and input in one input mode.

That is, if 'go' is the normal input, press '4' to enter 'g', '6' to enter 'm', then press '*' twice to convert 'm' to 'o' do. Since the sentence database 22 and the word database 26 do not have a key value including '*', there is naturally no data corresponding to the key value. The same applies to the phrase database 24.

When inputting two or more frequently used words 'go home', the word database 26, which is the method of 'T9', is used to input '46' and then 'go, in, ho', etc. corresponding to the key value. There is a hassle to choose 'home' from the corresponding words 'good, gone, home, hood, hoof, hone, goof' by selecting 'go' and then typing '4663' again.

'go home' is a frequently used phrase, so if you make it into a database, you can enter '464663' so that the phrase can be used as a word data without spaces.In other words, a word with many duplicates in one code can contain more than two words. When coded, corresponding data is reduced, making input easier than writing only word data. Of course, if you put 'go home' in the sentence data, the value becomes '44' which is the code value of 'gh' which is the first letter of each word.

The type of database to be used is the user's choice, and the terminal retrieves the data corresponding to the input code from each database so that the user can select the intended character string.

If there is no data that the user wants, it can be saved after input according to the input rules, and of course, input can be made without using the database in the same input mode at the first input.

In the above example, for convenience of description, an input value of two or three digits is used as an example, but as the number of digits of the input code increases, it is natural that the sentence and word data corresponding to the input value are not duplicated.

For example, 'I love you honey (4594)', 'Where are you going? (9294)', 'How are you doing? (4293)', 'That's a good idea (8244)', 'Meeting is running late ( 6475) 'does not have a corresponding word data code in the dictionary.

That is, the sentence database 22, the phrase database 24, and the word database 26 correspond to a single input code redundantly, but the actual duplication does not occur much, and inputs such as proper nouns, which are inevitably present in the database, are the same. In the input mode, text input is easier.

For reference, in the case of the telephone buttons, the vowel 'a, e, i, o, u' is placed one by one on the key value of '2, 3, 4, 6, 8', so '2, 3, 4, 6, 8' The word data code must be included regularly, whereas the sentence data code has a key value corresponding to the first phoneme of a word constituting a sentence, that is, a key value of a consonant, so that there is little duplication.

In the use of the sentence database 22, when inputting 'I love you' to accurately input the first letter of each word as 'Ily' to reduce the duplication of data, or to enter the first and end letters for each word Inputting a sentence, or inputting a paragraph by inputting only the first phoneme of each sentence by making a paragraph consisting of two or more sentences, or using a keystroke corresponding to the initial letter of each word when using the sentence database 22. Along with this, it is a matter of course that the user can indicate that the intended database is sentence data.

If the sentence data corresponds to more than one input code, it is difficult to display them on one screen at once, so 'I Love You' is displayed as 'ILY' and only the front of each word and the cursor goes to the corresponding 'ILY'. You can also have 'I Love You' appear on the display.

If the pattern of the sentence contains a word that is difficult to make a database such as proper noun, the code of the word can be treated as '*' and the part corresponding to '*' part can be input after selecting the sentence. . Of course, in this case, there is no change in the input mode. For numeric input, if you press the keyboard while holding the '#' key, the number is displayed instead of the letter.

In other words, if you press '2' key in English input mode, 'a' is displayed on the screen, but if you press '2' key while pressing '#' key, the number '2' is displayed. When entering simple numbers such as numbers, it is possible to simply enter numbers without changing the input mode.

Of course, when the '#' key works alone, it acts as a cursor movement key.

'!?.' Which defines the character of sentence when entering sentence data By specifying the etc, the number of sentence data corresponding to the same code can be reduced.

According to the present invention, when entering a name such as 'Carmen Electra' in the address book of the terminal and storing the telephone number, the terminal automatically assigns the speed dial number to '23' corresponding to 'C E', which is the front of each word. The user can press the header of the name of the person who wants to make a call and use it as if he or she has not memorized the speed dial.

Pressing 'CE', the forehead of the user's 'Carmen Electra', results in pressing '23', the speed dial number of 'Carmen Electra'.

Data duplicated in one code are displayed in alphabetical / alphabetical order as well. This can of course also be applied to the selection of ARS data. Referring to FIG. 5, an example using the terminal 44 connected to the ARS system 42 through a wired or wireless communication network will be described. That is, for example, when a title of a song is selected by ARS, the code is assigned to the sentence data and the word data so that the user can select the desired data by pressing a button of the phone as it is associated with the letter.

For example, if the title of the song is in the form of a single word, the title of the song is displayed when a close word is entered, for example 'yesterday', and in the case of multiple singers, detailed singer names are displayed. do. And if the title of a song is longer than two words, for example, 'My Way', the key value corresponding to the first letter of each word, but the song title with one word may have a lot of duplicates. Only the song title of the word has a key value generated by pressing one key per alphabet. In this case, if there are multiple singers, the choice can be made.

5 and 6, since one key is pressed per alphabet, the letter is not displayed correctly. In other words, 'yesterday' is not entered correctly as 'yesterday'. In other words, since ARS is treated as a numeric code instead of a character input, ARS does not have a display of characters, and even when searching by characters, 'yesterday' is not entered correctly. Just explain as above for better understanding.

When the user selects the title of a song on the phone, the one-word song is to press the key corresponding to each alphabet once, and more than one word is to press the key value corresponding to the first alphabet of each word once. You can choose a title.

Even if you search for a song by song lyrics, you can find the song by pressing the button corresponding to the first letter of each word of the lyrics only once. Type in to find the song you want.

You can also search by artist name.

Since the present invention is characterized by applying various databases to one input key value, the singer name, song title, and lyrics may be applied to one input key value.

You can also speed dial only the first digit of each number when you enter a frequently used phone number. In other words, when dialing '123-456-7890', the first letter of each string is dialed '147'. This saves the user the hassle of having to dial all phone numbers when the user is memorizing a phone number.

Press '147' and press the 'Call' button to call '123-456-7890'.

Or, if you press '147', '147' and '123-456-7890' are displayed together. If you are calling a phone number beginning with '147', you can continue to enter the number. If '123-456-7890' is the number you want, select '123-456-7890' and press the call button.

It can be used in general dialing mode instead of separate search mode, and it can be selected when two or more telephone numbers correspond to the same code.

2. For Korean

In the case of English, since there is already a standardized arrangement of buttons as shown in FIG. 1, it was described by applying them. However, in the case of Korean, there is no standardized arrangement and the format of the characters is not the same as English. Is bound to vary.

However, it has a basic character generation rule and separates the sentence database 22, the phrase database 24, the word database 26 and inputs in one input mode, regardless of which button array is used. The principle is the same.

The input method of Hangul not included in the data will be described based on the input method (hereinafter referred to as 'Hangul Unification 2000') based on the applicant's patent application No. 10-1998-0011031 filed on March 30, 1998. .

8 is an arrangement of buttons by 'Hangul Unification 2000', and the table below shows the input method.

Table 1

Example of key input by 'Hangul Unification 2000'

Referring to Table 1, the Hangul is composed of 19 Choseong ((), 21 Neutral (ㅏㅑㅓㅕ ㅗㅛ), and 27 Jongsung (ㄱ) It consists of two.

In the case of Hangul, it can be said that it is a space type character that is composed of a single character, which is different from English, which is the enumerated character. Hangul is used for consonants and vowels for neutrality and vowels for neutrality.

By using this, 'Hangul Unification 2000' arranges consonants and vowels together in one button, but without the distinction key of consonant vowels, the first button is pressed as first, the second button is neutral, and the third button is final Automatic recognition

Letters without a trailing letter follow the order of passing to the next letter by pressing the '#' key instead of the trailing word.Bokja consonants that are not in the basic consonants are selected with a leading consonant or a vowel and then selected with the '*' key.

For example,

1) Hong Gil-dong: '348586448' (9 strokes)

2) Flower: '5 ** 40 *' (6 strokes)

3) Soul: '975 *' (4 strokes)

-' 'Is not in KSX1001, so Jong-sung converts from' ㄱ 'to' ㄳ '. 4) Pig: '44 *** # 08' (8 strokes).

The present invention will be described below by applying the present invention to the input method of 'Hangul Unification 2000' described above and the applicant has already filed.

As mentioned in the English input, the present invention can selectively select one or more databases to be used by the user among sentence databases, phrase databases, and word databases.

For example, if you want to enter the sentence 'where are you now?' By using the sentence database, press 'ㅇ', the first consonant of each word, and this results in pressing '808' according to the arrangement of FIG.

Therefore, on the screen, the second type of 'ㅈ' is recognized as a vowel 'TT' according to the input rule of 'Hangul Unification 2000'. In other words, the word 'Wung' is displayed on the LCD and 'Where are you now?' Sentence data appears.

The user is displayed at the bottom of 'Where are you now?' By selecting the sentence, you can enter the sentence 'Where are you now?' With four key operations.

If the user uses the word database 26 together with the sentence database 22, the input of '808' is displayed with the letter 'Ung', and the first word of the three or more sentences is 'ㅇ'. The second word is one of the words 'ㅈ ㅊㅉ' and the third word is a sentence beginning with 'ㅇ', or the first letter is 'ㅇ' and the second letter is one of 'ㅈ ㅊㅉ' and the first letter is The word 'ㅇ' will correspond at the same time. For example, it could be a kindergarten.

If you input only the header to use the data but do not have the desired data, you can enter it again including neutral and final in the same input mode.

Of course, if '*' for subordinated input or '#' key is pressed when there is no finality during input, there is no corresponding data because there is no code value with '*' or '#' in the key value of the data. Of course, frequently used words such as 'hello' and 'hello' can be recorded in sentence data and displayed by pressing 'ㅇ' alone.

It is preferable to data two words, or a total of 5 to 7 letters in the phrase database.

In the case of 'accept me', the short text can be duplicated with two codes of '91 (ㄴㅂ) 'for inputting the sentence data, and' 9 (ㄴ) 'as the input method of the word data. And '180 (ㅂㅇ)' separately may be duplicated.

In this case, look at 'accept me' as one word and enter '9180 (ㄴㅂ ㅇㅈ'), which is the head of each letter. In this case, 'Nya' is displayed on the screen. In other words, the input value of '9180' means four or more words with 'b, ㅂ, ,, ㅉ ㅉ ㅉ 머리 ,, and 인, ㅂ ㅃ, ,, ㅉ ㅉ ㅉ Sentences or words above the word and phrase data having the code of 'b, ㅂ ㅃ, ㅇ, ㅈ ㅉ (9180), such as' accept me' stored in the phrase database 24, is' Nyan '.

This is also useful for recording times that are often used for short messages. For example, if you want to enter the character '5:30' as the header without changing to the numeric input mode, it will be '5 ㅅ 30 ㅂ (57301)' and the screen will read 'Junja' according to 'Hangul Unification 2000'. Is displayed. This can also be replaced with the string '5:30' if it is included in the data.

In the case of 'Hangul Unification 2000', consonants and numbers are arranged in 10 buttons, so you have a code of '5 power of 10' with only 5 inputs.

Of course, telephone numbers frequently used by users are also databased so that they can be entered without changing the numeric mode. In other words, when the sentence 'I love you good night' is entered as sentence data, the user presses the key corresponding to the heading of each word 'ㅅㅈ (70)' and 'number' is displayed on the screen. On the screen for “ㅅㄹ ㅎㅈ (76300)” and “Shuhu” on the screen (according to “KSX1001” 'Characters are not used) is displayed. When using word data, press 'ㅅㄹㅎ (763)' to select 'I love you' and then press 'ㅈ' to select 'Good night'.

Of course, input is also possible without the use of a database. 'I love you well' is a sentence of two words consisting of a total of five letters, so using the input method of the phrase data 'ㅅㄹ ㅎㅈ (76300)' is the way to reduce duplication.

The way you type is the user's authority and there is no change of input mode. The terminal retrieves the data from the database specified by the user according to the key value input by the user. Of course, the character string according to the character generation rule that the terminal has is displayed separately.

All the databases 20 can be used according to the user's choice, but in general, input the word data with 3 or more letters in mind, and when entering a word with 2 or less letters, a total of 4-7 letters or more of two or more words It is preferable to use a phrase database by entering it with no spaces.

Of course, a word of less than two letters may have a lot of overlap when using the word database 26. Therefore, it may be better to input using the method of 'Korean Unification 2000'. Any input listed above is processed in one input mode.

In the case of Hangul input, it is described based on 'Hangul Unification 2000' developed by the present applicant of the present invention, but the same may be applied to other Hangul input methods different from 'Hangul Unification 2000'. That is, in the case of a key array having consonants and vowels separated, only consonants are inputted when the header is pressed, which can be regarded as using a database. In this case, however, since there are usually 5 to 7 keys arranged with consonants, data duplication increases. Therefore, all data can be added and edited by the user.

You can also type 'where are you now' as the first letter of each word, 'Oji' and find a corresponding sentence. In this case, if there is no sentence in the sentence database, it is easy to input again.

In the case of Hangul, sentences with the same meaning can be expressed in high and low words depending on the opponent, and the difference appears mainly at the end of the sentence. Therefore, in case of sentence data, codes are formed by the first phonemes or letters of words, which can cause unnecessary duplication. have. In this case, if the first sentence data is input using the acronym, the second input sentence can also be solved by zooming on the acronym. After sending the short message once, the terminal may store the number and remember whether or not the sentence used is high. You might want to record the relationship to an address book feature that is already in use.

3. Simultaneous input of English and Korean

It is a feature of the present invention to provide a database with different input methods and different usage methods at the same time. Therefore, just as a sentence, phrase, word, and time database can be mapped to one input value, data of other languages can be mapped to that key value.

Based on the arrangement of Figure 7, if the Hangul sentence database and the English word database are used together, and the default display is in Korean, when the text 'LOVE' is entered, it immediately has the code '5683' and the word 'Kyuyo' on the screen. Is displayed. The meaning is that the first word starts with one of 'ㄱㅋ ㄲ', the second word starts with 'ㄹ', the third word starts with 'ㅇ' and the fourth word starts with 'ㅎ', or the first The letter is one of 'jkl', the second is one of 'mno', the third is one of 'tuv', and the fourth is an English word or 'Kyuyo' made up of one of 'def' (according to 'KSX1001' 'Is not).

The terminal displays data corresponding to the input key value, and the user can select an intended Hangul sentence, an English word, or 'Kyu'. Of course, you can attach Korean word data and English sentence data here.

4. Japanese input

Japanese input methods are divided into two types. It is a method of inputting in Japanese itself, and it is replaced by Japanese after it is written in English. For example, enter 'I' in Japanese as '일본어 た し は', and enter 'atasiha' in English.

It is clear that both methods can be used by applying the method described above, but it is clear that in Japanese, no word is used, but anyone who knows Japanese can distinguish a word without a space.

As mentioned above, Japanese can also use sentence database 22, phrase database 24, sentence database 26, etc., as in English or Korean.

If Japanese and English alphabets are arranged together on the buttons of the terminal, a character string that can be generated by the two input methods is applied by applying the method of inputting Japanese itself and the phonetic alphabet in English to one input key value. It can also display all of them and let you choose one of them.

The user can press the key and generate the corresponding character or string in a quick way to enter the character or string that he or she intended, or the character or string that is intended to be displayed among the corresponding characters or strings displayed in the database or Just select the string.

5. Input of Chinese

Chinese, like Japan, can be written in English, then replaced with Chinese, and entered in Chinese characters. The method of writing in English is also the same as above, and the notation of Chinese characters can also be used to write word data or sentence data by successively inputting only the first stroke of the Chinese character, or by inputting the first stroke and the last stroke. will be.

Chinese characters can be selected at the same time by inputting them in Chinese characters and replacing them with Chinese characters in English.

In the same manner as in the Japanese embodiment, the user can easily input a character or a string that he / she wants to input in two ways.

In the two input methods, the terminal displays data corresponding to the input key value on the screen, and the user selects the data intended by the user from the displayed data. Of course, when inputting by a method other than the basic input method by setting a separate designation key, it is natural that a user can designate the type of database he wants to use by pressing a specific designation key before or after inputting a key value.

In the case of a language with a large amount of data corresponding to the input code, as shown in Fig. 9, the button is divided into a main button (numbered buttons 52) and auxiliary buttons 54, 56, and the center number when the telephone number is pressed to make a call. Only buttons marked with In the text input mode, each button is operated separately, thereby increasing the accuracy of the input value by enlarging 10 buttons or more, thereby reducing the amount of data corresponding to the input key value.

In this case, it is a matter of course that a pointed touch pen such as an input pen can be used.

In the dialing mode, only the center main button is operated, so the key can be pressed with the finger regardless of whether the auxiliary button is touched.

Although the present invention has been described in detail by using the ten numeric keypad of the mobile phone as an example, it is obvious that the present invention can be applied to a PDA that can increase the number of the keypad as well as to a computer keyboard.

Therefore, according to the present invention, when a word or sentence is input by operating keys of various terminals such as a mobile phone, a WAP phone, a PDA, a web pad, etc., a phrase or sentence can be input with a minimum key operation. In particular, it is possible to input a phrase or sentence by simple key operation regardless of the language constituting the phrase or sentence and the key arrangement state of the terminal. In addition, when inputting a telephone number, an address, and various information on the ARS or the Internet, key operation is performed. There is an effect that can be minimized.

It will be apparent to those skilled in the art that various modifications and variations are possible within the scope of the present invention, and such modifications and variations belong to the appended claims.
