Description

Apparatus and method for inputting alphabetic characters on a keypad

technical field

The present invention relates to an apparatus and method for entering characters on a keypad, and more particularly, the present invention relates to an apparatus and method for entering characters from a keypad having fewer numeric keys, such as a telephone keypad.

Background technique

With the advancement of mobile communication, a function of receiving and transmitting digital information such as text messages has been added to mobile stations mainly used for voice calls. Therefore, the keypad for inputting telephone numbers on the mobile station additionally has the function of inputting characters, thereby reducing the size of the keypad used as the input means of the mobile station and limiting the number of keys on the keypad. The letters of each language generally exceed the number of 12 keys on a keypad. Therefore, there is a need to represent each character individually by a key on a telephone keypad, or as a combination of two or more different keystrokes.

Contents of the invention

Regarding the inventions disclosed in the prior art documents (application numbers: 10-2000-0031879 and PCT/KR00/00601) published by the present applicant, the contents thereof are summarized as follows.

First, the so-called "part-whole selection method (PWSM)" assigns characters to each given number of grids provided for each key of the keyboard, and the grids correspond to the key layout such that the user presses The first button of the target character associated with the second button on the keyboard just can input the character you want (hereinafter referred to as "target character"), and the setting position of the character in the grid of the second button and the first button Corresponding. For example, in Figure 1-1, the user may enter "A=[1]+[2]".

The core of PWSM is to use the partial grid unit of each button including the basic grid unit (BLE). Combined BLE is used in close order. Thus, the basic grid unit constitutes the core of the PWSM, and a keyboard utilizing the basic grid unit concept is called a "basic keyboard (BK)".

Then, the so-called "Basic Repeat Selection Method (BRSM)" enables the user to select characters according to the number of times a key is pressed on a basic keyboard designed to use PSWM in order of proximity to BLE, i.e. Order of Convenient Key Combinations (COBC). BRSM enables users to use the Repeat Selection Method (RSM) on the basic keyboard. For brevity, a keyboard using only RSM is called "Plain Keypad (PK)", and the RSM method used in PK as usual is called "Simple Repeat Selection Method (SRSM)".

There is also a "Control Processing Method (CPM)", which includes "Affix Control Processing Method (ACPM)" and "Sequential Control Processing Method (SCPM)". The affix control processing method is to input characters with affixes through the combination of affix control and basic characters. The sequential control process defines a set of characters assigned to a key as the relationship between a representative character and its successor characters, and combines the representative character with the priority associated with the representative character. For example, in Figure 4-1, the user can enter

The Affix Control Processing Method (ACPM) is actually similar to the Successive Character Control Processing (SCPM). The latter is broader than the former, since the specified character group also includes affixed characters belonging to the base characters in the order specified in SCPM. Because characters with affixes can be decomposed into affixes and basic characters, ACPM is very closely related to character groups in morphology, while SCPM is closely related to sequence and pronunciation.

The advantage of CPM is that, through the relationship between the base character and its successor (or affixed) character, the successor (or affixed) character is not displayed on the keypad in order to provide a simple layout of the keypad and input without ambiguity character. A keypad that does not include sequential characters is called "sequential keypad (SK)", and a keypad that does not include characters with affixes is called "easy keypad (AK)". Both SK and AK are called "Compact Keypad (CK)". A keypad showing all consecutive (or affix) characters is called a "full keypad (FK)" relative to CK.

The full keypad can also use the CPM to enter subsequent (or affix) characters, while the CK allows users who have memorized the full keypad layout to perform the input process on the full keypad. As mentioned above, CK can be expanded into FK, and users can conveniently input consecutive characters through CPM, which ensures the compatibility of existing technical documents.

The control process method not only eliminates ambiguity, but also simplifies the layout of the keypad by "hiding" successive characters by the relationship between representative characters and their successive characters as described in the prior art literature. For brevity, this approach is referred to as the "Hidden Control Processing Method (HCPM)". As described in the prior art literature, sequential (or affixed) characters can be entered by the CPM on the full keypad where the sequential (or affixed) characters are displayed. For brevity, this method is referred to as the "non-covert control processing method (NCPM)".

The present invention improves upon the prior art documents of the applicant (Application No.: 10-2000-0031879 and PCT/KR00/00601). Specifically, it provides (a) a method of entering commonly used characters using fewer keystrokes, (b) a method of entering all target characters using the Simultaneous Input Method (CIM) in order to reduce input keystrokes and thus improve The convenience of entering characters, said simultaneous input method is related to both the shortcut input method (SIM) and the full input method (FIM), (c) the method of inputting various symbols on the keypad, and (d) using As a mobile key method for controlling keys, the mobile key is not often used in the character input mode.

In a first aspect of the invention there is presented a method for recognizing alphabetic characters or 'words or phrases' intended for input, said method comprising the steps of:

receiving an input value from a keypad having a plurality of keys comprising at least three desired alphabetic characters respectively associated with and on which the three desired alphabetic characters are set character keys and control keys not associated with alphabetic characters, wherein the control keys include a first control key associated with the * character and a second control key associated with the # character;

identifying the first alphabetic character by a selection of one of the plurality of character keys; and

The second alphabetic character is identified by the combination of the first alphabetic character and the first control key, and the third alphabetic character is identified by the combination of the first alphabetic character and the second control key.

In a second aspect of the present invention there is presented a method for recognizing alphabetic characters or 'words or phrases' intended for input, said method comprising:

receiving input from a keypad having a plurality of keys some of which are character keys associated with a plurality of special alphabetic characters and some of which are not associated with alphabetic characters A control key, wherein the plurality of special alphabetic characters includes a first special alphabetic character and a second special alphabetic character;

identifying the first special alphabetic character by a combination of selection of one of the character keys and a selection of one of the control keys; and

The second special alphabetic character is identified by a combination of selection of the character key and two or more selections of the control key.

In a third aspect of the present invention there is presented a method for recognizing alphabetic characters or 'words or phrases' intended for input, said method comprising:

Receiving input from a keypad having a plurality of keys some of which are character keys associated with one or more alphabetic characters and up/down/right/ left movement key;

identifying a first alphabetic character from a plurality of alphabetic characters by selecting one of the character keys;

A second alphabetic character is identified from among the plurality of alphabetic characters by a combination of selection of the first alphabetic character and selection of one of the movement keys.

Detailed ways

The present invention will be described in detail below by means of examples, which are not intended to limit the scope of the present invention.

First, the contents of prior art documents are described in the following language. It is obvious that the content of prior art documents related to a certain language can also be applied to other languages, although not specifically stated.

1. General Supplementary Instructions

1.1 Application of prior art documents and small keyboard in the present invention

It is obvious that the keypad proposed in the prior art documents and in the present invention can be used in all applications having the form of a telephone keypad, including: a numeric keypad of a mobile terminal or a standard keypad, a keypad implemented on the screen in the form of software, or door lock. Although the numeric keypad of the standard keyboard is different from the prior art document and the keypad of the present invention in the layout of the numeric keys, the layout of the keys on the prior art document and the keypad of the present invention can be applied to the keypad of the keyboard . For example, in the prior art literature and the present invention, the characters assigned to the key [1] are set to the numeric key [1] of the numeric keypad of the keyboard, etc., the method therein can be applied to the input of characters, the use of simple codes and memories of different codes.

1.2 Continuous Keystroke Delay Time (SSDT) and Discrete Keystroke Delay Time (DSDT)

For some languages, such as Korean and Hindi, where consonants and vowels alternate, each key is assigned a representative pair of consonants and vowels, so that one keystroke enters the consonant and two keystrokes enters the vowel. An algorithm may be implemented to first recognize two keystrokes of a given key within a predetermined delay time (eg, 0.1 second) interval as a vowel and enable the user to effectively input the vowel. Given the typical time consumption of one keystroke in successive presses of the same key, a delay time must be determined. For simplicity, this delay time is called "sequential keystroke delay time (SSDT)". Additionally, an algorithm may be implemented to first recognize two keystrokes of a given key within a predetermined time (eg, 1 second) interval as consonants. For simplicity, this delay time is called "Discrete Keystroke Delay Time (DSDT)". This also applies to three or more keystrokes of the same key.

如果延迟时间为0.5秒，根据该语言中元音和辅音出现方式中表现的相应语言结构，就能够确定用户是要输入一个元音还是要输入两个辅音。甚至如果两次击键的延迟时间是0.08或者1.1秒时，也可以根据该语言中元音和辅音出现方式中表现的相应语言结构，确定是将两次击键识别为一个元音还是识别为两个辅音。For example, as shown in Figure 4-1, or 4-2, if the user presses the key[1] twice at an interval of 0.08 seconds, the two keystrokes are first recognized as vowels, i.e., And, if the delay time is 1.1 seconds, the two keystrokes are first recognized as two consonants, i.e. and

If the delay time is 0.5 seconds, it can be determined whether the user wants to input one vowel or two consonants according to the corresponding language structure represented in the way vowels and consonants appear in the language. Even if the delay between two keystrokes is 0.08 or 1.1 seconds, it can be determined whether to recognize the two keystrokes as one vowel or as two consonants.

By convention, a fixed time interval (e.g., 1 second) is used so that two consecutive key presses within the corresponding time period are recognized as two consecutive keystrokes, while two consecutive key presses within a time interval longer than the corresponding time Recognized as two discrete keystrokes. There is a difference between the reference time to recognize two consecutive keystrokes (eg, 0.1 second) and the reference time to recognize two discrete keystrokes (eg, 1 second).

In general, RSM is superior to PWSM in the prior art literature in terms of input convenience. Therefore, this method with the advantages of RSM (i.e. simple and convenient input rules) uses a specific language structure in which vowels and consonants alternate to avoid ambiguity, and simplifies the implementation of the algorithm in the following way: SSDT Distinguished from DSDT, and allows users to specify SSDT and DSDT.

1.3 Chain control processing method

之间关来说明代表性字符和其带词缀字符之间的关系，即

{送气辅音}和

{紧辅音}。但是，由代表性字符和其相继字符，如 (代表性字符)， (第二)和

(第三)之间的关系，在本发明中也可以得到相同的结果。According to the prior art literature, ACPM is actually similar to SCPM, and the latter is broader. That is to say, in the existing technical literature, take the Korean characters as an example and

to illustrate the relationship between representative characters and their affixed characters, that is,

{aspirated consonants} and

{tight consonants}. However, by representative characters and their successor characters, such as (representative characters), (second) and

The relationship between (3rd) can also obtain the same result in the present invention.

For the Japanese language shown in Figure 2-1, the following describes an example of using SCPM for input. In view of the relationship between representative characters and their successive characters, for example, あ (representative character), い (second), う (third), え (fourth) and お (fifth), あ is used with the key [ 1] (あ=[1]) to select, the second to fifth controls are assigned to control keys (such as [*]) and the selection is repeated according to the number of times the control key is pressed, in order to pass the representative character and its A combination of consecutive characters to enter consecutive characters. Conveniently, control selections are transcribed in square brackets. When the control is set to be selected after entering the base character, the resulting input is as follows: あ=[1], い=あ+{second}=[1]+[*], う=あ+{third} =[1]+[*]+[*], え=あ+{fourth}=[1]+[*]+[*]+[*], and お=あ+{fifth}=[1 ]+[*]+[*]+[*]+[*].

Again, relationships are established between representative characters such as あ (representative character), い (second), う (third), え (fourth), お (fifth) and their successor characters . Instead of assigning sequential control to control keys and using RSM, "sequential" or "sequential" control is selected by a single keystroke (eg [*]) of a specific control key. A second consecutive character (for example, い) is input using a combination of a representative character and "subsequent control", and a third consecutive character is input using a character preceding the second representative character (second consecutive character) and "subsequent control". character (for example, う). That is to say, う=い+{following}=[1]+[*]+[*]. Likewise, the fourth consecutive character ㈈ is input using the preceding character (third consecutive character) and "subsequent control" as the third representative character. That is to say, え=う+{follow-up}=[1]+[*]+[*]+[*]. The fifth consecutive character is also input in a similar manner.

This result is the same as that obtained when successive controls (second, third, fourth, fifth, ...) are assigned to the keys as controls selected by the RSM and the input is given by a combination of representative characters and successive characters . It can be seen that the input of the first representative character あ without ambiguity results in the input of the subsequent second consecutive character い without ambiguity. That is, え=い+{following}=[1]+[*]+[*], which makes it possible to input い without ambiguity. So the following character え can also be entered without ambiguity, because い is combined with "following control".

For brevity, this method is referred to as the "chain-type sequential control processing method (chain-type SCPM)", in which "subsequent" controls are used instead of sequential controls assigned to control keys, and successive characters are represented by A combination of the preceding character and the "following" control to enter consecutive characters. The prior art literature states that the user only recognizes a specific key as a sequential control key, even if the sequential control key is not marked with a sequential control. The advantage of the chained SCPM is that it simplifies the representation of "subsequent control" on the control buttons. The present invention uses the "Sequential Control Processing Method (SCPM)" in conjunction with the "Chain SCPM" because the former has the same results as the latter described in the prior art.

1.4 Jump Control Processing Method (JCPM)

ù，

和

。在带词缀字符中有五种类型的词缀，例如/，

...，和s。如果词缀控制按照下面的顺序选择：/，

...，和s，则输入必须由＝a+[*]+[*]给出。但是，词缀/不能带在字符“a”上，因为在法语中字符“a”仅有与 或者

两种组合。因此词缀“/”被遗漏(即跳过)，而词缀

被选择，以便得到输入＝a+[*]。为简便起见，这个系统称为“跳跃控制处理方法(JCPM)”。这就是说，JCPM将相继字符的附加优先权指定为a(基本字符)，à(第二)和(第三)，以便用与控制处理方法相同的方式输入相继(或者词缀)字符。in ACPM. Affixed characters including "¨" and "e" can be input by a combination of ¨ and e. Alternatively, e is indicated as the base character, and its successors related to the base character are assigned as successors for morphology and priority, so that the affixed character  can be assigned by the base character and additional priority (e.g. , e (basic character), é (second), ê (third)...) combined input. Additionally, affixes or successive characters can be entered without ambiguity by repeatedly pressing control keys that are assigned controls that become meaningful only when associated with characters (ie, specific numeric keys). For the Roman alphabet, use the 11 affixed characters in French, including: é, ê, è, , à, ,

ù,

and

. There are five types of affixes in affixed characters, such as /,

..., and s. If the affix controls are selected in the following order: /,

..., and s, then the input must be given by =a+[*]+[*]. However, the affix / cannot be placed on the character "a", because in French the character "a" is only associated with or

Two combinations. So the affix "/" is left out (i.e. skipped), while the affix

is selected so as to obtain the input =a+[*]. For simplicity, this system is referred to as the "Jump Control Processing Method (JCPM)". That is, JCPM assigns the additional priority of successive characters as a (basic character), à (second) and  (third) so that the successive (or affix) characters can be entered in the same manner as the control processing method.

Likewise, in Japanese, for the characters つ in the character rows あ, や, and た, there is a long sound, and there is a voiced sound in the character rows か, さ, た, and ほ, and a semi-voiced sound occurs in the character row ほ. Therefore, the character つ has two affixed characters, long and voiced. And the ほ line has two affixed characters, voiced and semi-voiced. Thus only one keystroke of a given affixed control key can enter all but six affixed characters having characters other than two affixed characters. For example, when the control key is set to [*] and the control is set to be selected after inputting a basic character, then an input such as あ=あ+[*] and が=か+[*] is obtained. For six characters each having two affixed characters, the affixed characters are entered with the controls selected in order of frequency of use of the affixes. For example, when the control key is set to [*], and the control is set to be selected after the basic character is input, the input can be given as: つ=つ+[*], づ=つ+[*], ぼ=ほ+[*] and ぽ＝ほ+[*]+[*]. That is, the controls are selected in such a way that controls that can be combined with the base character have no effect. For example, [*] is not a long tone control but a voiced tone control in the input が=か+[*] given below because the basic character か does not have a long tone and it must be combined with a voiced tone control.

The advantage of strict selection control is that characters that are not actually used in the input can be entered. It is also possible to enter, for example, dummy characters in French including b and the affix "¨", and Japanese characters including あ, as well as voiced sound points.

Even if the control is selected by the repeat method (RSM), only if the representative character marked on the keypad can be entered without ambiguity through the control process (for example, when there is only representative character 1 on key 1, or even when the character is located at When using an unambiguous character input method such as the Part Whole Selection Method (PWSM) on each key, other consecutive characters can be input without ambiguity. The reason is that ambiguity is dispelled by control processing because controls can represent specific characters not only alone but in combination with other characters.

1.5 Input numbers and English letters by control processing method

The prior art literature states that the native language, numbers and English letters are arranged "in order of proximity to BLE" and are selected by RASM in the same manner. Likewise, numbers and English letters (except Roman letters), as well as native languages can be entered by SCPM.

Digits or English letters can be assigned immediately after the native consecutive characters. For example, Japanese characters are ordered according to あ (representative character), い (second), う (third), え (fourth), お (fifth), 1 (sixth), . (seventh), q (eighth), z (ninth), and so on in order to dispatch. If control buttons for numbers or English letters are available, the control buttons for あ (representative character), い (second), う (third), え (fourth), and お (fifth) are assigned to certain key (for example, [*]) and the control key for numbers or English letters is assigned to the second key (for example [#]), so that numbers and English letters start with あ (representative character), 1 (first), . (second), q (fourth), and z (fifth) to enter. For example, the input is given by 1=あ+[#]=[1]+[#], .=あ+[#]+[#] and q=あ+[#]+[#]+[#] =[1]+[#]+[#]+[#]. Control keys for numbers and English letters are provided separately, if available.

This can be applied to other languages and various notations explained below.

1.6 Pronunciation-Based Grouping of English Alphabet Characters

The prior art literature builds a keypad for each language in such a way that the characters are grouped by similar pronunciation and assigned to each numeric key for purposes of CPM usage and memory usage of the codes. For English, a widely used method groups three or four characters lexicographically, and assigns character groups to each numeric key. Likewise, characters can also be grouped for similarity in pronunciation, and groups of characters are assigned to each numeric key. For example, the consonants of the English alphabet fall into the following nine groups based on their pronunciation similarity:

BP/CSX/DT/FVH/GKQ/JZ/LR/MN/WY

BPV/CSX/DT/FH/GKQ/JZ/LR/MW/NY

Alternatively, the consonants of the English alphabet fall into the following eight groups:

BFPV/CGKQ/SX/DT/JZ/LR/MWH/NY

BFPV/CGKQ/SX/DT/JZ/LR/MN/WYH

In addition to the above two examples, other variations are possible. The five vowels are appropriately set in two groups of consonants. This ensures the convenience of applying the shortcut input method (SIM) using simple codes, which will be described later. For non-English languages, the character groups constructed above can be assigned to each key given the pronunciation similarity between the native language and the English language. For Korean, for example, G, K, and Q groups are assigned to characters that sound similar to G, K, and Q button. For Japanese, G, K, and Q are a group of keys assigned to the character "か" that sounds similar to G, K, and Q. Therefore, English alphabets can be grouped considering the grouping patterns of each native language.

2. Supplementary instructions based on language

In the following, supplementary explanations and improvements to the content of prior art documents are given in the following language. It is obvious that, although not specifically stated, the content of prior art documents referring to a certain language can also be applied to other languages.

2.1 English

As described in the prior art literature, using the CPM to input successive characters on a full keyboard, it is also possible to input the English alphabet marked on the keyboard in addition to the representative characters. Sequential control, ie the second and third controls are assigned to the same control key (eg key [#]) or different keys (eg keys [*] and [#]). For example, A, B and C of the English alphabet can be considered to be assigned to common control keys. If the representative character is A, successive characters B and C are independently input through successive control processing. Otherwise, if the representative character is B, successive characters are independently input through SCPM. In view of the frequency of use described in the prior art literature, additional priorities for representative characters and successive characters can be specified.

For example, when A is a representative character in the group of A, B and C, and after the representative character is entered, control is exerted using the second and third controls assigned to the key [*], then the input B= A+{second}=[2]+[*], and C=A+{third}=[2]+[*]+[*]. If B is the representative character and after entering the representative character, control is exerted using the second and third controls assigned to the keys [*] and [#] respectively, then the input A=B+{second}=[ 2]+[*], and C=B+{third}=[2]+[#]. 1-2 illustrate example layouts of keyboards designed for easy character recognition, wherein the middle character of each set of characters is designated as a representative character, and successive characters are located to the left and right of the representative character. For example, D=E+{second}=[3]+[*].

In the case where the four characters of P, Q, R and S are assigned to the key [7], and the four characters of W, X, Y and Z are assigned to the key [9], as in the prior art literature, the Korean language is As noted in the example, it is adapted to PWSM in such a way that one of the four characters can be assigned to a grid cell forming a vertically adjacent combination (VAC). As shown in Figure 1-3.

2.2 Japanese

Existing technical documents indicate that Japanese characters are grouped for the Japanese syllabary, and the characters in the あ column, that is, あ, か, さ, etc., are used as representative characters and other characters are used as consecutive characters for sequential control processing . Regarding the Japanese syllabary in the following table appearing in the same manner as method 3 of the prior art document, the additional priority of successive characters is determined. This makes the grouping method very familiar to the user due to the simplification of the additional priorities. As explained in the prior art literature, ん can be regarded as a representative character. Another option is that the characters of the syllabary (for example, い, う, or え) or ん are regarded as blanks belonging to the column of や or わ. Method 3 of prior art literature Simple application of 50 tone table basic network unit second third fourth fifth basic network unit second third fourth fifth a い u え o a い u え わ ka ki く け ko ka ki く け ko sa し す せ so sa し す せ so ta chi つ te to ta chi つ te to na ni ぬ わ no na ni ぬ ね no wa hi ふ へ ほ wa hi ふ へ ほ ma み む め も ma み む め も ya Yu ょ ya Yu yo ra ri ru れ ろ ra ri ru れ ろ わ を ん わ を

Although the prior art documents indicate that the characters in the first column are conveniently designated as representative characters, the representative characters can be in any column or be any character belonging to the group, as explained in the prior art documents, each A row of characters may be assigned to each key according to the row of keys on the keyboard (ie, [1], [2], [3], [4], . . . ). Or dispatch by key column (ie, [3], [6], [9], [2], [5], . . . ). Alternatively, instead of assigning characters to each key by row or column, a random assignment can be made.

Taking the Japanese language as an example, the existing technical literature has explained that when "ん" is arranged at the position of the basic grid unit of the button [0], the second and third buttons respectively assigned to the button [*] and the button [#] are used. Control, "ん" is assigned to numeric keys other than key [0] so that key [0] is used as a control key for inputting long/voiced/semi-voiced sounds. Instead of using control keys additionally provided for long/voiced/semi-voiced sounds in order of proximity to BLE (OPBLE), "ん" is set at the position of the basic grid unit of key [0]. RSM can then be adapted to control the selection, since there will be no discontinuities of "ん" in a word. As shown in Figure 2-1. This method of selecting a discrete occurrence of a character in a word can be applied to all other languages using one keystroke of the corresponding key and other controls of two, three or more keystrokes of that key. This feature is also applied to the method using Korean vowels described later.

2.3 Arabic

There are 28 consonants in Arabic. According to the prior art literature, the Arabic consonants representing numbers are grouped and assigned to each key on the keypad, and the characters representing the smallest number are designated as representative characters and arranged in the basic network. The position of the grid cell, other characters are assigned to the keys on the keypad according to the order of proximity to the BLE (OPBLE). The prior art document provides a method of inputting Roman, Korean, Hindi and Arabic characters by way of controlled processing. It also provides a way to enter Arabic characters in which rare vowels are treated as affixes and affix-controlled.

Now, a description will be given below of a method of controlling the processing (ie, sequentially controlling the processing) of Arabic consonants. The table below shows a sample layout of Arabic consonants on each key.

Among the characters assigned to the key [1] represented as 1, 10, and 100, the character representing 1 is designated as a representative character, and the other characters representing 10 or 100 are sequentially controlled as described in prior art documents , any key can be designated as a control key. If the successive control keys are assigned to the key [*], using the second and third controls arranged, it is possible to input consonants with an average of two keystrokes. Since each key is assigned to only one character, it is not necessary for the PWSM to select the character marked on the key. The arrangement of characters is conceptual, so, as described later, characters are not assigned to the keypad.

According to the prior art document, as in the case of Japanese, the successive control is separated as another key. For example, when the third control is assigned to the key [#], the average number of keystrokes entered is about 1.7 (=(1+2+2)/3), and as described in the prior art literature, there may be no more Input 28 consonants meaningfully.

The present invention designates a character representing the smallest number as a representative character of each group, and selects a character of a smaller number among successive characters of other units regardless of the frequency of use. Controls to be selected may be set before or after inputting representative characters.

If successive controls are assigned to keys [*] with the character of 1 unit designated as the representative character, and the control is selected before the representative input, the input of 10 units is given thus and Perform the same steps for other characters. In this case, the key [#] can be used for vowel control processing.

另一种选择是，由于表示100的字符具有这样的形式：在其中上点被加于表示70的字符，即

所以在控制处理中，上方点控制优先选择给各种元音控制。这就是说，如果控制在输入字符之前施加于上方点控制，则输入这样给出 另一个包括上方点的字符也可以使用ACPM和其它输入方法同时输入。在这种情况下，将按键[0]用作为控制按键以用于其它目的(例如，元音控制按键)就变得非常容易。If the control is applied using only one character representing 1000, assigned to key [0], before entering the representative character, enter given like this The characters representing 1000 can be treated as those belonging to the first group, in which case the input is given by

Another option is, since the character representing 100 has the form in which dots are added to the character representing 70, i.e.

Therefore, in the control process, the upper point control is preferentially selected for various vowel controls. That is, if the control is applied to the upper point control before entering a character, then the input is given by Another character including the dot above can also be input simultaneously using ACPM and other input methods. In this case, it becomes very easy to use key [0] as a control key for other purposes (eg vowel control keys).

另一种选择是，输入

这样给出

同根据已有技术文献在日本语的情况下一样。如果表示1000的字符属于第一组字符，并且控制在输入字符之前应用，则输入这样给出

或者 这就是说，第二，第三和第四控制分派给按键[*]，第三和第四控制分派给按键[#]。考虑到阿拉伯人从左向右书写，可以将第二，第三和第四控制分派给按键[#]，而第三和第四控制分派给按键[*]。If the third control (i.e., the 100 unit control) is assigned to the key [#] alone, the character representing 200 is given thus

Alternatively, enter

given like this

Same as in the case of Japanese according to prior art documents. If the character representing 1000 belongs to the first group of characters, and the control is applied before the character entered, the input is given like this

or That is, the second, third and fourth controls are assigned to the key [*], and the third and fourth controls are assigned to the key [#]. Considering that Arabs write from left to right, the second, third, and fourth controls can be assigned to the key [#], while the third and fourth controls can be assigned to the key [*].

This means that frequently used characters, i.e. Arabic consonants, are entered unambiguously with an average of 1.7 keystrokes. The advantage is that it is easy to select characters that are not marked on the keypad (for example, 1-unit characters, that is, representative characters). That is to say, the present invention can be applied to a numeric-only keypad for inputting characters needed in daily life (for example, consonants in Arabic), only if the user is clear about the unit character designation as a given representative character or assignment A given control key and the rules for sequential control order, when assigned to a single control key, or whether the control is set to be selected before the representative character.

Control processing of vowels can be performed as described in prior art documents. When both key [#] and key [*] are used for consonant control processing, characters representing 1000 are assigned not to key [0] but to key [1] so that key [0] is designated as the element sound control keys, and input vowels as affixes in RSM (for example, vowel control or affix control), as in the case of Japanese according to prior art documents. The number of times the keys are processed in order of frequency of use, this method selects vowel controls (vowels as affixes). If only a single key [*] is used as the sequential control key for consonants, the control key for vowels can be key [#], or both key [#] and key [0].

In the examples of Figures 3-1, 3-2, although characters representing 1 to 9 (1-unit characters) are designated as representative characters for each group, the most frequently used character in each group can be the representative character. To avoid confusion, representative characters may be any of 1-unit characters (characters representing 1 to 9), 10-unit characters (characters representing 10 to 90), and 100-unit characters (characters representing 100 to 900).

Also, the characters selected for successive control may be each unit character based on frequency of use. For example, if the 100-unit character with the highest frequency of use is designated as the representative character, and the 1-unit character immediately follows the 100-unit character in frequency of use, the second control (i.e., 1-unit control) and the representative character can be used combination to input 100-unit characters, and a combination of the third control (ie, 10-unit control) and representative characters can be used to input 10-unit characters.

Successive characters can be entered by the CPM as described in the prior art document, consonants can be entered by the SCPM and vowels can be entered by the ACPM on the keypad of the prior art document. If on the 3*4 small keyboard, the key [0] is designated as the affix control key of the vowel, the control key of the consonant input can be either the key [*] or the key [#].

2.4.1 Separation of aspirated and tight consonant controls

并且

Referring to Fig. 4-1, as described in the prior art literature, the aspirated consonant control is assigned to the button [*] and arranged at the position of the basic grid unit, and the tight consonant control is arranged at the unit next to the basic grid unit, so that the control One keystroke of the key selects the aspirated consonant control, while two keystrokes of the control key selects the tight consonant control. However, when an extended vowel (ie, two vowels) is input, a time delay is essentially given between the two vowels so that there can be virtually no ambiguity even when the extended vowel cannot be input by the CPM. Also as in the case of the Japanese language according to the prior art document, the aspirated consonant control is additionally assigned to the key [#] and arranged at the position of the basic grid cell so that the aspirated consonant control is selected with one keystroke of the key [#] . As shown in Figure 4-2. If the control is set to be selected before representative characters, the input is given by

and

2.4.2 Control processing of basic vowels

The prior art document for said application (Prior Art Document No.: 10-2000-0025183) describes the use of a consonant and vowel pair where the key [#] is designated as a sequential control key and the control is set to To be selected before (or possibly after) the number keys so that the basic vowels are entered in the same way as in the case of Japanese. This means that the basic vowel control is arranged as shown in Fig. 4-3 so that the basic vowel can be input by the CPM without ambiguity. As pointed out in the prior art literature, the basic vowels marked on the keypad cannot be entered through the same control process as in Japanese (ie, entering successive characters through the control process on the full keyboard).

相同的规则可以应用于其它元音和扩充元音的情况下。相似的扩充元音的输入这样给出 和

This is less convenient than repeatedly selecting the base vowel using two keystrokes of the corresponding key, but completely removes the ambiguity. It is of course necessary to select "Basic Vowel Control" for entering basic vowels with one keystroke of the control button, because basic vowels are used very frequently. Figures 4-3 show an example of adding a "basic vowel control" that controls the processing of basic vowels to a graph of a prior art document. The basic vowel control is selected with one keystroke of the control key, and the extended vowel control is selected with two keystrokes of the control key. If, in the example in Figure 4-3, the control is set to be entered after the representative character, the input is given by

The same rules can be applied in the case of other vowels and extended vowels. The input of similar extended vowels is given by and

Since there is no close relationship between the representative consonant and the basic vowel, the basic vowel is marked on the keypad and input using the non-hidden control processing method.

2.4.3 Common use of aspirated consonant control and extended vowel control

When inputting both subsequent consonants (ie, consecutive consonants) and subsequent vowels, a sequential control key can be used, as explained in the case of Thai according to the prior art literature. For example, both the aspirated consonant control and the extended vowel control are arranged in the same grid cell of the control key. As described in the prior art literature, if the control keys for processing subsequent consonants are separated from the control keys for processing subsequent vowels, the order in which each control key is pressed can be specified differently (i.e., before or after a representative character). ).

2.4.4 Programming

Figure 4.4 is not only a flowchart for implementing the invention, but also enables more efficient programming. For example, it is more efficient to program by checking whether a consonant forms two final consonants, taking into account the final consonants of Fig. 4-4.

The Korean example presented in the prior art literature can be applied to other languages with similar features (ie, structures with alternating consonants and vowels). For other languages, the characteristics of consonant and vowel occurrences in the corresponding language can be considered.

In the Korean example, the first three keystrokes (inputs 1, 2 and 3) are always determined by the consonant and vowel of the first symbol (letter) from "word start". Of course, this doesn't work in the case of Hindi, where the sign including "vowel+consonant" comes first. Input 4 may be the last consonant of the first symbol (letter) or the first consonant of the second symbol (letter). Although all the detailed illustrated steps are not described in the flowchart of the prior art document, it can be determined whether input 4 is the same as the previous input (ie input 3). If so, it can be determined in advance that input 4 and input 5 cannot form a diphthong, because input 4 and input 5 should not be the same vowel, so that the already determined input 2 and input 3 can form a diphthong. Otherwise, if input 4 is different from the previous input, in a later step as shown in the flowchart, input 4 is compared with the next input (input 5).

和

一旦确定了一个符号(字母)，输入5看作下一个重复操作中的输入1。如果输入5与输入4相同，并且输入2和输入3没有形成双元音，输入4确定为第一符号(字母)的末辅音，输入5确定为第二符号(字母)的词首辅音。尽管没有示出流程图，这当然可以在已有技术文献的本发明编程中加以考虑。If input 5 is the same as the previous input, check to see if inputs 4 and 5 form a diphthong. Now, the case where input 4 and input 5 do not form a diphthong will be described. If the input 5 is different from the previous input, the input 4 is determined to be the last consonant of the first symbol (letter), and the input 5 can be the double last consonant of the first symbol (letter) or the first consonant of the second symbol (letter) . Therefore, it is determined whether input 4 and input 5 form a double-final consonant. If not, input 5 is determined to be the first consonant of the second symbol (letter). This is because among the 196 (14*14) combinations of 10 flat consonants and 4 aspirated consonants in Korean, there are no more than 11 possible combinations, for example,

and

Once a symbol (letter) is determined, input 5 is treated as input 1 in the next iteration. If input 5 is the same as input 4, and input 2 and input 3 do not form a diphthong, input 4 is determined to be the last consonant of the first symbol (letter), and input 5 is determined to be the initial consonant of the second symbol (letter). Although no flowchart is shown, this can of course be taken into account in the programming of the invention in prior art documents.

”)，就可以检查下一个输入(为简便起见，称为“输入x”)是否为“单词的末尾”。如果这样，输入x确定为末尾音节(字母)的末辅音(例如，“

”)。When diphthongs can be formed, the same steps as in the flow chart are performed. In all other cases that lead to ambiguity, if an unambiguous word (syllable (letter)) has one part ending in a suffix (final consonant) and another part not ending in a final consonant (e.g., "

"), you can check whether the next input (for brevity, "input x") is "the end of a word". If so, input x is determined to be the last consonant of the last syllable (letter) (for example, "

").

2.4.5 Combination of tight consonants and flat consonants

As described in the application's prior art document, tight consonants can be handled using flat consonants in all Korean keypads. For simplicity, Figure 4-1 gives the reference.

”)。甚至当第一音节以末辅音为结尾，并且第二音节的词首辅音为紧辅音，第一音节的末辅音与第二音节的词首辅音(例如，“

”)一样时，第一音节的元音和“第一音节的末辅音+第二音节的第一辅音(例如， )被识别为双元音(仅当

”形成双元音时)。如同已有技术文献中发明的特点，由于在输入紧辅音时没有实现由CPM来排除多义性，所以多义性非常严重。If tight consonants can be entered using a combination of two flat consonants, the steps are performed in the same way as in the case where input 4 equals input 5. Although the convenience of entering characters is increased in this case, when the first syllable without any consonant ends in a vowel, and the first consonant of the second syllable is a tight consonant, ambiguity occurs (for example, "

"). Even when the first syllable ends with a final consonant and the initial consonant of the second syllable is a tight consonant, the final consonant of the first syllable and the initial consonant of the second syllable (eg,

") same, the vowel of the first syllable and "the last consonant of the first syllable + the first consonant of the second syllable (for example, ) is recognized as a diphthong (only if

"When forming diphthongs). As the feature invented in the prior art documents, since the CPM is not implemented to remove ambiguity when inputting tight consonants, the ambiguity is very serious.

of ambiguity. Another example given is

In the latter case, there are 8 diphthongs in Korean (in the case of two combinations of flat consonants instead of three), including

and they all start with or for the end. if five consonants

and

The three consonants and three vowels in and

split into consonant and vowel pairs, this avoids even when entering tight consonants with two flat consonants ambiguity, so correctly identify

在第一音节(字母)具有末辅音，而后续的音节(字母)以紧辅音为开头的情况下，这可以防止将输入紧辅音时相同按键的两次连续击键误认为是元音。Recognition in this case is possible by simply grouping the characters into groups instead of changing the existing algorithm (checking if the characters form diphthongs)

In the case where the first syllable (letter) has a final consonant and the subsequent syllable (letter) begins with a tight consonant, this prevents two consecutive keystrokes of the same key when entering the tight consonant from being mistaken for a vowel.

However, in the case of words starting with a tight consonant, i.e. the first consonant of a word of the first syllable (i.e. input 1 and input 2 are the first consonant as a tight consonant, input 3 and input 4 are vowels, i.e. consonant + Vowels), the flowcharts of prior art documents have to be modified, which is obvious to those skilled in the art. In this case (at the beginning of a word, input 1 and input 2 are determined as tight consonants, and inputs 3 and 4 are determined as vowels, i.e. "consonant + vowel"), when all inputs are activated by selecting the same key When inputting 1 to 4, the case where input 1 is the first tight consonant is confused as a flat consonant, input 2 and input 3 are vowels, and input 4 is the last consonant (ie, consonant+vowel+consonant). In some cases, by checking whether the next input (called "input x" for brevity) forms the final consonant of "consonant+vowel" and the double final consonant of "consonant+vowel+consonant", and ends the word, this ambiguity can be avoided, and if the input x cannot form a double-end consonant and end the word, the input x is processed as the end consonant of "consonant+vowel". Even when the input x forms a double consonant, do the same steps for the next input.

If a combination of two flat consonants is used to process tight consonants, the ambiguity can be considered to be caused by RSM. Ambiguity can be avoided by "indexing" which will be described below.

Therefore, using a combination of two flat consonants to process tight consonants increases the ambiguity caused by using RSM, but improves the convenience and simplicity of inputting characters.

Word recognition can be achieved by any means of recognizing a word based on one of the following, such as a space, mode shift, shift key, confirmation, or end of input.

2.5 Hindi

According to the prior art literature of the present application, the consonants of Hindi are divided into 9 groups, which are assigned to the keys [1] to [9], and one keystroke of the key [0] is used to select the assignment to the key [0] vowels. For consistency, in the present invention, consonants are divided into 10 groups so that representative consonants are selected using one keystroke of the corresponding key, and 10 vowels are selected using two keystrokes. The vowel ___ (ri) is not assigned to the keypad and it is rarely handled by the CPM. The division of consonants into 10 groups can be considered to be achieved using pronunciation similarity as described in the prior art literature. An example of grouping consonants into 10 groups is given below.

When the first vowel of Hindi, (a) is ignored when it is between two consonants. That is to say, the consonants appear one after the other. In this case, when typing "consonant + (a) + consonant, it is easy to display "consonant + consonant". Of course, typing can also give "consonant + consonant" like this, in this case, consecutive Enter the same representative consonant, and two consonants will be mistaken for a vowel. (Vowlet ___(a) is automatically ignored or ignored by the user) are allowed.

2.6 Burmese

There are 33 consonants in Burmese. An example of 9 consonant groups is given below. Alternatively, the consonants are divided into 10 groups following the same pattern.

3. Minimize ambiguity through mathematical models when using a pair of flat consonants and basic vowels

In languages with recurring consonants and vowels such as Korean, Hindi, and Burmese, the 10 basic vowel and peace consonant pairs are assigned to the keypad and RSM is used so that with less ambiguity to efficiently enter the characters on the keys.

For Korean, tight consonants, aspirated consonants, and extended vowels can be input by combinations of CPM, ie, control and basic characters. For Hindi, consonants added to representative consonants are input through sequential control processing. The present invention provides a method of minimizing ambiguity in inventions of prior art documents.

If multiple characters are assigned to a key, and RSM is used, ambiguities as described in the prior art literature arise due to the inherent nature of RSM. For example, when successive inputs of "AB" are assigned to the same key, such as [2]+[2]+[2], confusion can arise in determining whether the input is "AB" or "BA".

For brevity, in the case of Korean, almost all syllables consist of "consonant + vowel (ie, first consonant + middle vowel)" or "consonant + vowel + consonant (ie, first consonant + middle vowel + final consonant)". This rule is similar to other languages such as Hindi and Burmese. However, Korean is characterized in that one syllable constitutes one word (ie, one square character).

One of the main situations where ambiguity occurs is when the first syllable includes "consonant+vowel" and the second syllable includes "consonant+vowel+consonant" and "vowel+consonant" of the second syllable is assigned to the same key . In this case, the initial consonant of the second syllable is regarded as the last consonant of the first syllable, and "vowel+consonant" of the second syllable is regarded as "consonant+vowel". In order to reduce ambiguity, obviously, consonants and vowels in a syllable including "consonant+vowel+consonant" (ie, "consonant+vowel") are not assigned to the same key. That is, a vowel and a consonant that are often changed from a vowel (middle vowel) to a consonant (final consonant) in a syllable including "vowel+consonant+vowel" are not assigned to the same key. For Korean, ambiguity occurs when the first syllable includes "consonant+vowel+vowel" or the second syllable includes "consonant+vowel+consonant+vowel", but not so much. More specifically, for a Korean word whose second syllable includes "consonant + vowel + consonant + vowel", the combination of vowel and consonant and the frequency of vowel-consonant transition are considered.

Judging from the opposite point of view, when the first syllable includes "consonant+vowel+consonant" and the second syllable includes "consonant+vowel", and the second syllable including "consonant+vowel" is assigned to the same key , the first syllable is recognized as "consonant+vowel", and the second syllable is recognized as "consonant+vowel+consonant" combined with the last consonant of the previous syllable. To minimize ambiguity, consonants and vowels that are often combined in a syllable in the form "consonant+vowel" should not be assigned to the same key. In Korean there are some cases where the first syllable includes "consonant+vowel+consonant+consonant". These situations are not very common.

The prior art literature describes other situations leading to ambiguity, but in practice such situations are relatively rare. Thus, the present invention provides a method that minimizes ambiguity in both cases. This method can also be applied to any consonant-vowel sequence language such as Hindi and Burmese, and Korean, and more specifically, to consonant-vowel sequences other than Korean. In other languages where the sounds appear in the same way, it will be easier to implement the invention. FIG. 4-4 shows a flow chart (disclosed in prior art literature) for character recognition when RSM selects Korean flat consonants and basic vowels assigned to the keypad with reference to FIG. 4-1. The figure also shows situations where ambiguity occurs.

Hereinafter, the present invention will be described by taking the Korean language as an example.

About 50% (precisely, 54.011%) of syllables in Korean include "consonant+vowel", and about 50% of syllables include "consonant+vowel+consonant". Therefore, it can be considered that the frequency of transition from consonant to vowel (hereinafter referred to as "consonant-vowel conversion" or "consonant-vowel combination") in a syllable consisting of "consonant+vowel" is the same as that in a syllable consisting of "consonant+vowel". +consonant" from vowel to consonant (hereinafter referred to as "vowel-consonant conversion" or "vowel-consonant combination") frequency is almost the same. If Korean or other languages have about 70% of syllables consisting of "consonant+vowel" and about 30% of syllables consisting of "consonant+vowel+consonant", it can be considered that the consonant-vowel conversion weights about 30% (because Ambiguity caused by consonant and vowel transitions occurring on the same key on the assumption that the previous syllable at the end of "consonant+vowel+consonant" is 30% and the vowel-consonant transition is weighted about 70% (because Under the premise that the previous syllable at the end of "consonant+vowel" is 70%, the conversion of vowel and consonant on the same key causes ambiguity).

The frequency of vowel-consonant conversion is disclosed in the technical literature below. The 21 vowels (middle) and 27 consonants (end) in Korean result in 567 cases of vowel-consonant switching, and 270 cases of vowel-consonant switching actually occurred. The largest number of 12 cases accounted for 51%, while the largest number of 48 cases accounted for 90%. This large difference in binding frequency allows for a substantial reduction in ambiguity by optimizing consonant and vowel grouping. According to the invention, in the conversion of vowels and consonants, it is not possible to consider all cases, but the conversion of vowels and consonants marked on the keypad can be considered. In the case of a tight vowel-consonant combination or an aspirated-consonant combination, "control" intervenes, as described in the prior art literature, and the ambiguity is resolved. In the present invention, 100 vowel-consonant transitions are considered in order to minimize ambiguity, since 10 basic vowels can be combined with 10 flat consonants.

The frequency of consonant-vowel conversion is disclosed in the technical literature below. Now, a description is given below regarding the frequency of syllables including "consonant+vowel". The syllable comprising "consonant+vowel+consonant" is considered in conjunction with vowel-consonant conversion and will not be described further, which is an important factor of the present invention. There are 100 cases of consonant-vowel transposition using the 10 flat consonants and 10 basic vowels marked on the keypad.

The vowel-consonant conversion frequency and the consonant-vowel conversion frequency in the above table are not relative values but absolute values, so they are combined to form a table representing the combination frequency of consonants and vowels. The table below represents the sum of vowel-consonant transition frequencies and consonant-vowel transition frequencies. Specifically, in Korean, syllables including "consonant+vowel" accounted for 54%, constituting 54% of the frequency of vowel-consonant conversion, and syllables including "consonant+vowel+consonant" accounted for 46%, constituting 46% of Consonant-vowel transition frequency. But the table below shows that like the consonant-vowel conversion frequency, the vowel-consonant conversion frequency is 50%, because in Korean, the "consonant+vowel" syllables are divided equally between those "consonant+vowel+consonant" syllables.

Minimizing ambiguity in using RSMs on keypads is a well-known NP-hard problem. As described in the prior art literature of the present application, on a keypad marked with consonant and vowel pairs, in using (basic/simple) RSM to input consonants with one keystroke and vowels with two keystrokes, ambiguity The minimization of linearity can be modeled by linear programming (LP), which is an important advantage of the invention of the present application. The above table is an integrated frequency table representing the integrated frequency, which is used to optimize the mathematical model of the present invention.

Forming consonant pairs for minimizing ambiguity is called "grouping problem", since the term "grouping" used in the prior art literature means: the characters to be assigned to each key are divided into groups, and the term "assignment" means: assign groups of characters to each key, and the term "arrange" means: arrange each character on each grid cell of the key.

If the index of each row is defined as i, the index of each column is defined as j, and the number of assigned consonants or vowels is n, the objective equation and constraint expression are given as follows:

Min $\underset{i=1}{\overset{\mathrm{no}}{\mathrm{\Σ}}}\underset{j=1}{\overset{\mathrm{no}}{\mathrm{\Σ}}}{c}_{\mathrm{ij}}{x}_{\mathrm{ij}}$

Si． $\underset{i=1}{\overset{\mathrm{no}}{\mathrm{\Σ}}}{x}_{\mathrm{ij}}=1,$ i=1,2,...,n

$\underset{i=1}{\overset{\mathrm{no}}{\mathrm{\Σ}}}{x}_{\mathrm{ij}}=1,$ j = 1, 2, ..., n

x _ij = 0, 1  i, j

Among them, when the i-th vowel and j-th consonant are not in a group, x _ij is equal to 0, or when the i-th vowel and j-th consonant are in a group, x _ij is equal to 1; c _ij is the i-th The combined frequency of vowel and j-th consonant appearing in succession.

The target expression can be rewritten as:

Min Z＝(781736 ^★ × ₁₁ )+(26197 ^★ × ₁₂ )+...+(453225 ^★ × ₁₁₀ )

+(1255910 ^★ × ₂₁ )+... +(690618 ^★ × ₂₁₀ )

: :

+(471502 ^★ × ₁₀₁ )+, ... +(58296 ^★ × ₁₀₁₀ )

Constraint expressions can also be rewritten. With the mathematical model and defined coefficients (ie switching frequencies or combining frequencies), it can be solved by commercial LP (Linear Programming) packages. The solution to the equation is given below, with coefficients equal to the value of the above integrated frequency divided by 50 due to limitations of the program used by the applicant:

TOTAL COST＝12,241

However, grouping to minimize ambiguity is not optimal, since the recognition of character positions on the keyboard is also a very important factor.

If the problem of minimizing the switching (or combining) frequency is solved, the consonant and vowel pair that minimizes ambiguity can be detected. Otherwise, if the problem of maximizing the switching frequency is solved, ambiguity is increased, but there are more cases of pressing the same key to input characters, and thus, the convenience of input is improved. Unfortunately, users have to efficiently resolve the problem of ambiguity.

The maximization of conversion (or combination) frequency is considered to be effective in the following cases: select the confirmed key by syllable (Korean alphabet) with arranged vowel pairs so that consonants and two Press the key once to enter a vowel, or select the Enter key to confirm a syllable. In this case, all consonants and vowels not marked on the keypad can be entered without ambiguity in the following manner: successive controls are assigned to keys which are not considered confirmation control keys, and according to the repetition frequency of the control keys to choose. However, this will cause trouble for the user to press the syllable confirmation key. As stated in the prior art literature, a sequential control key can be applied to either subsequent consonants or Applies to subsequent vowels. This is of course the same as if the application had no confirmation key to enter the syllable.

Maximize the solution objective expression for converting (or combining) frequencies by appending a minus sign "-" to the coefficients (i.e., frequency numbers), or using values obtained by subtracting each coefficient from the largest coefficient as a coefficient in solving the minimum problem The formula is "Max Z =...". This can also be solved by means of commercial LP packages.

Although not all possible situations can be considered, the core of the embodiments of the present invention is to explain those situations that lead to more ambiguity (for example, vowel-consonant conversion, consonant-vowel conversion, etc.), and provide a basis according to these situations A method to optimize the combined frequencies of middle consonants and vowels.

The core of the method of using mathematical models to minimize ambiguity is summarized below. 10 consonants and 10 vowels grouped in pairs, each consonant and vowel pair assigned to each key so that consonants can be selected with one keystroke per key and vowels can be selected with two keystrokes per key . Here, ambiguities often occur involving consonant shifts (vowels and consonants combine in syllables consisting of "consonant+vowel+consonant") and consonant shifts (in syllables consisting of The consonants and vowels are assigned to the same key. For this, the linear programming method uses an "integrated frequency table" representing the coefficients in modeling the assignment problem, according to the number of frequencies per transition.

The same applies to other languages (for example, Hindi and Burmese) where one syllable consists of "consonant+vowel" or "consonant+vowel+consonant". For languages other than Korean, data on consonant and vowel conversion (conjugation) frequencies are available in the prior art literature, otherwise data is collected with a suitably designed technical literature library in the manner described in the case of Korean. That is, as stated above, if 70% of Hindi syllables include "consonant+vowel" and 30% include "consonant+vowel+consonant", then the frequency of vowel-consonant shift is 70%, while the consonant-vowel transition frequency is 30%. In Hindi, a syllable consisting of "vowel + consonant" is mistaken for "consonant + vowel" (disregarding the preceding syllable). To avoid ambiguity, the frequency of this kind of vowel-consonant conversion (for simplicity, hereinafter referred to as "0-vowel-consonant conversion" or "0-vowel-consonant combination") is set to 100%, so as to obtain the Integrated frequency tables, and consonants and vowels are grouped into consonant and vowel pairs in order to minimize the integrated frequency table.

According to the existing technical literature, 10 basic vowels and 9 representative consonants are divided into vowel and consonant pairs. For this purpose, pseudo-consonants are added so that the same grouping as the grouping of 10 consonants and 10 vowels is performed. The conversion (or combination) frequencies of pseudo-consonants and 10 basic vowels are set to "0".

(例如，[8]+[0]+[0]+[#]+[#]+[0]+[*]+[#])中，元音单元“.”后连续出现两次元音 并且因此“[#]+[#]”不会被认为是选择紧辅音控制，而是元音。由于元音单元“.”不是这个示例中单词的末尾，所以选择元音单元“.”之后的[#]不会被认为是选择元音。甚至如果送气辅音和紧辅音控制分派给指示为 的按键，由于元音 极少相继出现，所以没有多义性。There is no ambiguity in the present invention, where aspirated consonants and tight consonants are controlled with vowel units and

Share a key and apply RSM. The reason for this is that the vowels It is so seldom that two consecutive occurrences in a word are so characteristic of Korean that two keystrokes [*] used to select the aspirated consonant-controlled keys would not be considered to select two consecutive vowels and can also use this for vowels in the case of. in word

(For example, [8]+[0]+[0]+[#]+[#]+[0]+[*]+[#]), the vowel unit "." appears twice consecutively And thus "[#]+[#]" would not be considered to select tight consonant controls, but vowels. Since the vowel unit "." is not the end of the word in this example, the [#] after the select vowel unit "." is not considered to select a vowel. Even if the aspirated and tensed consonants controls are assigned to the keys due to the vowels Rarely occur in succession, so there is no ambiguity.

9 of the 10 flat consonants are assigned to the 9 keys [1] to [9]. The remaining one is not assigned to a key, and, for brevity, it is called "Consonant Out of 9 Keys (COO9)". In view of the similarity in pronunciation and morphology, consonants other than the 9 keys are considered as consecutive characters or affixes of one of the 10 flat consonants, and are controlled. For example, if the control is applied before a character is entered, while

is not assigned to a key but will be seen as

Affixed characters (aspirated consonants or tight consonants), input like this gives or

or

Considering the pronunciation and morphology in Figure 4-5, the regarded as

Affixed characters (aspirated consonants or tight consonants), input like this gives or or

是控制处理的一个示例，因为它是没有送气辅音也没有紧辅音的字符中使用频率最低的字符。选择作为控制处理的示例的另一个原因是发音和形态的相似性，如同另一个普通发音和送气辅音之间的关系。In this case, the characters that control processing (i.e., the ) is preferably a single character with no aspirated or tight consonants (eg: and ), for easier character entry. Of course, the basic characters that control processing (i.e., the ) is preferably a character without an aspirated consonant or a tight consonant, so as to facilitate character input. Here, given

is an example of control processing because it is the least frequently used character among characters with neither aspirated nor tensed consonants. Another reason for choosing an example as a control treatment is the similarity of pronunciation and morphology, like the relationship between another common pronunciation and aspirated consonants.

需要使用相应按键的三次击键来选择

以便消除RSM中的多义性，因为“.”相继出现两次非常频繁。在这种情况下，尽管 没有安排在实际上与基本网格相邻的第三网格上，用户仅需知道使用相应按键的三次击键。这意味着按键[0]的三次击键选择 并且所有平辅音可以安排在各自的数字键，以便于记忆。Here, 10 flat consonants (ordinary pronunciation) are preferably assigned to 10 numeric keys for use in Korean for memorizing phone numbers and various codes. For this purpose, the additionally assigned to keys indicated as "." (i.e. key[0]) and assigned to the grid for selection using three keystrokes of the corresponding key

Requires three keystrokes of the corresponding key to select

In order to eliminate the ambiguity in RSM, because "." appears twice very frequently in succession. In this case, although Not arranged on a third grid that is actually adjacent to the basic grid, the user only needs to know three keystrokes to use the corresponding key. This means that three keystrokes of key[0] select And all flat consonants can be arranged in their respective number keys for easy memory.

To make the characters more visible in Figures 4-5, consonants are marked in blue, vowels and vowel units in red, and numbers in black. The _ marked in blue on key[0] indicates assignment to key[0] because ".+_+0 (zero)" is morphologically similar to

That is, consonants beyond the 9 keys are treated as affixed characters for specific flat consonants, and are entered with CPM, or entered using three keystrokes of the key indicated as "."

4.1.2 Flat consonant combination processing of tight consonants, and hidden/non-hidden repetition selection processing of tight consonants and aspirated consonants

之类的多义性(第一多义性，整个代码中的多义性)。In the method using Korean vowel units, tight consonants can be processed in the form of combinations of flat consonants. Because in the method using vowel units, a flat consonant is assigned to each number key, occurrences such as

Ambiguities like (first ambiguity, ambiguities throughout the code).

This ambiguity can be avoided by using "indexes" as described in the examples below. If the aspirated consonants are input in a combination of flat consonants, the CPM is only used to input the aspirated consonants in order to simplify the input rules. As described in the prior art literature, aspirated consonant controls can be assigned to appropriate grid cells. For example, move the aspirated consonant control into Figure 4-1 or Figure 4-2.

并且

)可以相继输入平辅音，送气辅音和紧辅音(例如，

和

)。如已有技术文献所述，这种情况会有第一多义性。这里不对导致多义性的特定示例进行说明。可以在按键上单独标记平辅音，所有的平辅音，送气辅音和紧辅音。这样就可以允许要由RSM选择的相继字符(例如，

和

)。It has been explained above that according to the number of times the corresponding key is pressed (for example,

and

) can successively input flat consonants, aspirated consonants and tight consonants (for example,

and

). This situation has a first ambiguity, as described in the prior art literature. Specific examples that lead to ambiguity are not illustrated here. Flat consonants, all flat consonants, aspirated consonants and tight consonants can be individually marked on the key. This allows successive characters to be selected by RSM (eg,

and

).

(第二)，和 (第三)。这就是说， 并且 [1]+[1]+[1]。这就是通过平辅音的组合来处理紧辅音(或者隐藏重复选择处理)和通过隐藏重复处理来选择送气辅音。For brevity, the method in which only representative characters are marked and their successors are selected by RSM is called "Hidden Repeated Consonant Processing Method (HRSPM)". Additional priority for aspirated and tight consonants may be given in the order of flat, tight and aspirated consonants. For example, the assignment of grid cells is defined like this: (first: position of base grid cell),

(second), and (third). This means that, and [1]+[1]+[1]. This is the combination of flat consonants to process tight consonants (or hidden repetition selection processing) and hide repetition processing to select aspirated consonants.

Although this method of the invention differs from the hidden repetition selection method described in the prior art literature in the additional priority of successive characters, it is also possible to use two keystrokes (combinations of flat consonants) of the corresponding number keys to enter tight consonants, thus making the input more natural from the user's perspective.

这样就整体提高了所采用的方法的一致性，因为

和

之间的关系与普通音(平辅音)和送气辅音在形态和发音上的关系相似，并且也可以使用相应数字按键的三次击键来输入送气辅音。In this case, use three keystrokes of key[0] to enter

This overall improves the consistency of the method used, because

and

The relationship between them is similar to that between ordinary sounds (flat consonants) and aspirated consonants in morphology and pronunciation, and the aspirated consonants can also be input using three keystrokes of the corresponding number keys.

一样，或者通过CPM，其中

same, or via CPM, where

considered as suffixed characters. When the user inputs an aspirated consonant through the CPM, the system will recognize the aspirated consonant without ambiguity (the ambiguity in the entire code, ie, the first ambiguity). However, despite entering aspirated consonants using three keystrokes of the key assigned to the corresponding flat consonant, ambiguity still occurs. You can also apply this to tight consonants.

的输入这样给出“ 这就是说，第一

由CPM输入，而第二 由RSM输入。同样， 的输入这样给出 That is, the user can enter aspirated consonants on the same keyboard either by CPM or by hiding the repetition selection method. You can also apply this to the case of tight consonants. For example, if two keystrokes of the key [*] are used to select the aspirated consonant control, and two keystrokes of the keys corresponding to the respective base characters are used to select the aspirated and tight consonants, then

The input like this gives " That is to say, the first

input by the CPM, while the second Input by RSM. same, The input is given like this

The order of selecting the aspirated consonants and the tight consonants may be defined to facilitate the user to input the aspirated consonants and the tight consonants using the non-hidden repetition selection method or the hidden repetition method.

4.1.3 Combinations of methods using flat consonants and basic vowel pairs and methods using vowel units

The system using vowel units is a simplified version of the keypad shown in Figures 4-1, 4-2, and 4-3, and is compatible with character entry methods disclosed in prior art documents. That is to say, the character input method of the present invention can be applied to the small keyboard that additionally marks 10 basic vowels on the button, can also be applied to mark all flat consonants, basic vowels, extended vowels, aspirated consonants and tight consonants. keyboard.

和

的八个基本元音被分配给九个按键[1]到[9]中的八个，以致于使用指示基本元音的按键的两次击键来选择八个元音。同样，CPM或者重复选择处理方法可以应用于送气辅音和紧辅音的输入。例如，如果除

之外的八个元音添加入图4-5，如图4-2所示， 的输入这样给出

如果方便，用户可以通过RSM来输入 的元音 并且使用指示元音单元的按键来输入 的元音 在这里，不必要改变输入模式，尽管输入一个单词可以应用不同的输入方法。In the example of Fig. 4-2, the tense consonant control and the aspirated consonant control are assigned to keys [*] or [#], which are not necessarily specifically marked on the keyboard, but are clear to the user. According to the present invention, or Markings are placed on each key so as to allow the user to select the method of using vowel units or the method of using flat consonant and basic vowel pairs. For example, in Figure 4-5, as the vowel unit exists except

and

The eight basic vowels of are assigned to eight of the nine keys [1] to [9], so that the eight vowels are selected using two keystrokes of the key indicating the basic vowel. Likewise, the CPM or repeated selection processing method can be applied to the input of aspirated and tight consonants. For example, if you remove

and

The other eight vowels are added into Figure 4-5, as shown in Figure 4-2, The input is given like this

If it is convenient, the user can enter through RSM the vowel and use the keys that indicate vowel units to enter the vowel Here, it is not necessary to change the input mode, although a different input method may be applied to input a word.

)，分派给没有用来指示元音的按键，随后应用RSM。在这种情况下，“索引”的帮助可以克服可能发生的多义性。Alternatively, the eight vowels are additionally assigned to keys [1] to [9], two flat consonants that have no aspirated or tense consonants and are similar to each other in morphology and pronunciation (e.g., or

), assigned to a key not used to indicate a vowel, and then RSM is applied. In this case, the help of "index" can overcome the ambiguity that may occur.

5. Methods to overcome ambiguity through indexing

这两个单词在图4-1中具有相同的代码。与此相连，一个客户终端或者服务器准备这些可能导致多义性的单词的索引，所述的多义性与特定键盘和特定单词的输入方法相关。如果用户输入

或者

甚至在一定的时间延迟在后也不能将其与其它的单词区分开来，系统就会认为

是想要的单词(下文称为“目标字符”)，因为 被看作索引中的正确单词。这仅应用于系统对两个单词之间发生的多义性不可区分的的情况。如果可能，系统(客户侧或者服务器侧)通过时间延迟值的帮助来区分单词，这可以事先由系统或者用户设置。这就是说，当用户输入

并有意地暂停(通过时间延迟，空格，或者左移动键的选择，或者另一个特殊按键的选择)时，系统输出作为目标单词的

尽管输出的单词在语法上是一个不正确的单词。In RSM, having multiple words represented by the same code leads to ambiguity. As described in the prior art literature, this ambiguity occurs in the example in Figure 4-1 and between. Usually it is entered word by word. For example, there are words without words

These two words have the same code in Figure 4-1. In connection with this, a client terminal or server prepares an index of the words that may cause ambiguity related to a specific keyboard and a specific word input method. If the user enters

or

Even after a certain time delay, it cannot be distinguished from other words, the system will consider

is the desired word (hereinafter referred to as "target character"), because is seen as the correct word in the index. This should only be used in cases where the system cannot distinguish between ambiguities that occur between two words. If possible, the system (client side or server side) distinguishes words with the help of a time delay value, which can be set beforehand by the system or the user. That is, when the user enters

And when intentionally paused (by time delay, space, or the selection of the left movement key, or the selection of another special key), the system outputs the

Although the word output is grammatically an incorrect word.

)。另一种选择是，系统既登记正确的单词又登记不正确的单词，设其具有确定索引中的特定单词是正确还是不正确的信息。In preparation for indexing, the system only registers the correct words (eg, ) or incorrect words as ambiguous words (eg,

). Another option is for the system to register both correct words and incorrect words, provided it has the information to determine whether a particular word in the index is correct or incorrect.

和 之间发生多义性的情况。它也可以应用于下面的情况：辅音和元音对分派给如图4-1所示的每个按键，以便使用相应按键的一次击键来选择辅音，使用两次击键来选择送气辅音，使用三次击键来选择紧辅音，和一次击键选择元音，并且音节确认键是由音节(字母)选择的音节(字母)。甚至当系统暂时输出与由用户输入的

相对应的

时，在单词结束的时刻(例如，输入空格)，参考索引，就会将拼错的单词纠正为

This can be applied to all situations where RSM is used on the numpad. For example, the same applies to Samsung Electronics Co., Ltd.'s input method in

and Ambiguity occurs between them. It can also be applied in cases where consonant and vowel pairs are assigned to each key as shown in Figure 4-1, so that consonants are selected with one keystroke of the corresponding key, and aspirated consonants are selected with two keystrokes, Three keystrokes are used to select tight consonants, and one keystroke to select vowels, and the syllable confirmation key is the syllable (letter) selected by the syllable (letter). even when the system's temporary output differs from the user-input

Corresponding

When , at the moment when the word ends (for example, enter a space), refer to the index, and the misspelled word will be corrected as

When indexes of words exist in both the client and the server, the system first looks for the correct word in the client's index, and if that fails, finally in the server's index.

As fully understood, with the help of word recognition coefficients, the system can distinguish one word from another, such as between spaces, between the beginning of a word and a space, between a space and the end of a word, and a space It is given between and mode transitions. Referencing the index to determine word correctness can be done word by word. Therefore, when the user enters word recognition coefficients, the system refers to this index to determine the correct word.

和

之间产生，其中单词的末辅音和词首辅音属于相同的按键。在这里，当使用通过字符分派的代码来输入字符时，系统不能一个音节(字母)一个音节(字母)地识别，以致于必然输出与小键盘输入的

相对应的

在这种情况下，即使经过一定的时间延迟之后，如果能够确定两个单词中的哪一个应该是目标单词，则系统(终端或者服务器)参考索引来确定目标单词。在这种情况下，与时间延迟无关，参考索引来确定目标单词可能更有效，因为在所有的情况下，系统将目标单词确定为

即使

的词首辅音 在

的末辅音

后被选择。This applies to all cases where ambiguity occurs in RSM. For example, in the input method of South Korea's Samsung Electronics Co., Ltd., ambiguity can be found in

and

produced between , where the final consonant and the initial consonant of a word belong to the same key. Here, when using codes assigned by characters to input characters, the system cannot recognize them syllable (letter) by syllable (letter), so that the output is necessarily the same as that of the keypad input.

Corresponding

In this case, even after a certain time delay, if it can be determined which of the two words should be the target word, the system (terminal or server) refers to the index to determine the target word. In this case, regardless of the time delay, it may be more efficient to refer to the index to determine the target word, since in all cases the system determines the target word as

even though

initial consonants of exist

the final consonant of

selected after.

Obviously, this is not limited to Korean, it can be applied to all languages using RSM. For example, when the user enters [2]-[2]-[2] in the case of English characters in English mode or other languages, resulting in ambiguity between "AB" and "BA", the system recognizes "AB" registered in the index as a correct word is retrieved and provided as a target word. If all the polysemous words entered are registered in the index as correct words, the system will first provide the user with the most frequently used word, and enable the user to finally determine the target word

If the system recognizes all words corresponding to the ambiguous input word as correct words of the reference index, it allows the user to select the target word with the help of an appropriate (visual or auditory) method.

In order to allow the user to determine the target word, the system lists a plurality of words that are considered correct words according to the frequency of use (or priority) on the display screen, and makes the user use the corresponding up and down scroll keys or Numeric keys to select the target character. Another option is for the system to display only the most frequently used word on the display and, if the word is not the target word, prompt the user to select a control (referred to as the "following word control" for simplicity) for display The next most frequently used subsequent word. If the subsequent word is also not the target word, the system enables the user to select the target word in the same way. After the target word is searched, the user is allowed to determine the target word by selecting another key (ie, any key other than a control indicating a subsequent word, such as another character, a space, or a mode transition).

Here, both PWSM and RSM (basic/simple) can be applied to subsequent word-controlled choices. If the subsequent word control is dispatched at the base grid cell's position of a particular key, it can be selected with one keystroke of that particular key.

6. Simple code application method and SIM/CIM

6.1 Generation of character-related codes

When using a data communication terminal to access an information system, the input of characters is absolutely necessary. There are some cases where these characters are encoded as numbers. Miniaturized data communication terminals usually have an interface in the form of a common keyboard. Here, the term "symbol" refers to any type of code, examples of which are numerous, including: telephone numbers, stock index (listed companies) codes, subway codes, bank codes, etc. The encoding of the various names has the advantage of simplifying the input.

The data communication terminal used here includes any type of data communication terminal such as PC, mobile communication device, smart phone, PDA, two-way text transceiver, ATM (automatic vending machine), etc., and such as electronic diary. Information system as used herein includes any system that is visually accessible through a GUI or only visually accessible, such as ARS. The system also includes a server system and, in a broader sense, client software for terminals in communication with the server system.

The letters assigned to the keypad can be used to memorize different codes. There are various methods for this purpose, including: simple naming, initial naming or full naming. A description is now given below.

和 相关的简单代码“1799”，如图4-2所示。在这种情况下，与简单代码“1799”相关的 中的字符

和 用粗体标记，以致于用户容易注意到特定单词的简单代码。而且，可以从单词或者短语中提取简单代码。例如，

的简单代码不专门限于“1799”，因为在简单命名中，代码包括与属于给定单词的任何字符相关的数字。例如，随着

的简单代码设置为与 和 相关的值，

的代码可能变成与

和 相关的“1729”，或者是与

和

相关的“1949”，以及与所有构成 的字符相关的“13294293”。为简便起见，指定与形成一个给定单词或者短语的所有字符相关的代码被称为“完全相关简单命名(FASN)”，并且指定与形成一个给定单词或者短语的部分字符相关的代码被称为“部分相关简单命名(PASN)”。在这两种情况下，简单命名(即，简单编码)与构成给定的单词或者短语的字符相关。同样可以应用于其它语言和朝鲜语。例如，“caption”可以具有作为部分相关代码的与辅音“CPTN”相关的简单代码“2786”为简便起见将其称为“辅音相关简单代码”。Simple naming is the assignment of numbers associated with a given word or phrase as a code. For example, a Korean company name, has a

and The relevant simple code "1799", as shown in Figure 4-2. In this case, the associated simple code "1799" characters in

and Simple codes marked in bold so that the user easily notices a particular word. Also, simple codes can be extracted from words or phrases. For example,

The simple codes for are not specifically limited to "1799", because in simple naming, the codes include numbers associated with any character belonging to a given word. For example, with

The simple code is set up with and the associated value,

The code could become the same as

and related to "1729", or the

and

related to "1949", and with all constituent The characters related to "13294293". For brevity, assigning codes associated with all the characters that form a given word or phrase are referred to as "Fully Associated Simple Naming (FASN)", and assigning codes associated with some of the characters forming a given word or phrase are referred to as For "Partially Associated Simple Naming (PASN)". In both cases, simple names (ie, simple codes) relate to the characters that make up a given word or phrase. The same can be applied to other languages and Korean. For example, "caption" may have a simple code "2786" related to the consonant "CPTN" as part of the related code, which is referred to as a "consonant related simple code" for brevity.

和

的简单代码“8314”。对于英语，已有技术文献示例中的“data tonight”可以具有与带有语音值，例如d，t，t和n的字符相关的简单代码“3886”。Phrases and words can be encoded by simple names. According to the phrase in the example of the prior art literature , meaningful words (syllables) for extraction are mapped as

and

The simple code "8314". For English, "data tonight" in the prior art literature example may have a simple code "3886" associated with characters with phonetic values such as d, t, t and n.

Prefix naming is a special case of partially relative simple naming. For Korean, the initial designation designates numbers mapped to initial consonants of syllables (letters) as codes. For brevity, this method is called "Syllable (Letter) Initial Naming (SBIN)". For example, extracted from syllable-based initial naming The syllable-based initial code for is "1799" associated with the initial consonant of each syllable (letter). Syllable-based initial naming can be applied to other languages as well as Korean. For example, according to syllable-based prefix naming, the English word "entertainment" has a syllable-based prefix code "3886" associated with e, t, t, and m. Syllable-based initial naming is more useful for Korean, where one syllable forms one letter.

和

的词首字符相关的词首代码“81”。根据基于单词的词首命名，英语短语“dancewith the wolf”具有与d，w，t和w相关的基于单词的词首代码“3979”。当代码分派给整个短语时，基于单词的词首命名对于每种语言更为有利。Similarly, initial naming can also be applied in phrases. For example, the phrase in the prior art literature example may have with each word

and

The prefix code "81" associated with the prefix character of . According to word-based prefix naming, the English phrase "dancewith the wolf" has a word-based prefix code "3979" associated with d, w, t, and w. Word-based prefixes are more beneficial for each language when codes are assigned to entire phrases.

For simplicity, simple codes (i.e., fully correlated simple codes and partially correlated simple codes) and prefix codes (i.e., syllable-based prefix codes and word-based prefix codes) are all referred to as "simple codes (in the wider )" or "shortcut code". In particular, each of the complete relative simple codes, consonant relative simple codes, syllable-based prefix codes, and word-based prefix codes follows their generation rules, and is thus commonly used in practice. In addition, the code generated by other methods according to the rules is also easy to use.

Fully named is the value entered to encode a given word or phrase according to a particular character input method, and thus varies with the character input method used. The numeric value corresponding to a given word or phrase is encoded character by character. For example, as shown in Figure 4-2, according to the PWSM (disclosed in the prior art document), the prior art document Has the full encoding "7745888944". According to the BRSM (disclosed in the prior art literature), The full encoding of becomes "7448884". If another keypad or another character input method different from that in Figure 4-2 is used, a specific full code value can be given according to the keypad or character input method.

6.2 Generation of Simple Tone-Based Codes

)，第二音调(音调符号 )，第三音调(音调符号

)，第四音调(音调符号

)，和无音调。五个音调中的每一个都分派给小键盘上的两个按键。在这种基本模式中，可以得到不同的布局。例如，第一音调分派给按键[1]和[2]，第二音调分派给按键[3]和[6]，第三音调分派给按键[4]和[7]，第四音调分派给按键[8]和[9]，而无音调分派给按键[5]和[0]。为了便于使用，这样就把第一到第四音调分配给小键盘的上，下，右和左键。如果一对按键在颜色上彼此不同，在视觉上会更为有效。按键对按照[1，2][3，6][4，7][8，9]来分派，以形成一个卍形。另一种选择是，第一到第五音调中的每个依次分派给10个按键[1]到[10]中的两个。For the input of ideographic characters, such as Chinese characters, many characters must be properly assigned to the keys on the keypad. One approach is to map the English phonetic spellings corresponding to the characters on the English keyboard. Another approach is to map the tones of Chinese characters to keys on the keyboard. Chinese characters have five tones, the first tone (diacritic

), the second tone (the diacritic ), the third tone (diacritic

), the fourth tone (diacritic

), and no tone. Each of the five tones is assigned to two keys on the keypad. In this basic mode, different layouts can be obtained. For example, the first tone is assigned to keys [1] and [2], the second tone is assigned to keys [3] and [6], the third tone is assigned to keys [4] and [7], and the fourth tone is assigned to keys [8] and [9], while no tone is assigned to keys [5] and [0]. For ease of use, this assigns the first to fourth tones to the up, down, right and left keys of the keypad. It is more visually effective if a pair of buttons are colored differently from each other. Key pairs are assigned as [1, 2] [3, 6] [4, 7] [8, 9] to form a swastika. Alternatively, each of the first to fifth tones is assigned to two of the ten keys [1] to [10] in turn.

The problem that arises is that it needs to be determined which of the keys [1] and [2] should be used to designate the character with the first tone. There are multiple solutions to this problem. For example, one method involves classifying Chinese characters by number of strokes (ie, a way to determine complex forms of Chinese characters). If the number of strokes of a character with the first tone in a word or phrase is equal to or less than a predetermined value (for example, 5), it is considered that the character is assigned to button [1] (that is, the value in buttons [1] and [2] is higher small buttons). Otherwise, the character is considered to be assigned to key [2] (ie, the key with the higher value among keys [1] and [2]). In the above example, although the reference number of strokes is 5, it is not fixed as the average number of keystrokes of commonly used Chinese characters, but the reference value is set so that the number of keystrokes of half of the Chinese characters is less than the reference value, while the other The number of keystrokes for half of the Chinese characters exceeds the benchmark value.

Instead of using the number of strokes, the number of constituent characters can be used to determine the complexity of Chinese characters. The term "constituent characters" as used herein refers to recognizable characters in Chinese characters. For example, "cheng" includes two constituent characters "tu" and "cheng", while "ban" includes three constituent characters "mu", "mu" and "shi". If the number of constituent characters in a given Chinese character is equal to or less than a predetermined value (for example, 2), it is considered that the Chinese character is assigned to the one of the two keys corresponding to the same pitch that has a smaller numerical value. Otherwise, if the number of constituent characters exceeds a predetermined value, it is considered that the Chinese character is assigned to a key with a larger value.

Figure 5-1 shows the tones of Chinese characters. In the present invention, the tone symbols usually use the form shown in Figure 5-1. Fig. 5-2 is a schematic diagram of a keypad according to the present invention, wherein diacritical marks are marked on the keys of the keypad. Because the first tone is assigned to keys [1] and [2], the first diacritic Marked on keys [1] and [2]. The first diacritic marked on key [1] is smaller than that on key [2], which allows the user to intuitively tell that the complexity (i.e., number of strokes or constituent characters) is less than or equal to a predetermined level (e.g., 5 A Chinese character of the second keystroke or 2 constituent characters) should be assigned to the key [1]. Referring to Figure 5-2, multiple Chinese characters can be encoded on the keypad as follows. In the example below, the benchmark value used to determine the complexity of a given Chinese character is "5 keystrokes". The symbols above the characters are diacritics.

People's University=>3686 (the " person " of the second tone not only corresponds to the button [3] but also corresponds to the button [6], and thinks that it is relevant to the button [3] because its number of strokes is 2, which is less than the predetermined stroke reference The value is 5. The rest of the characters also apply this method)

People's Daily＝＞3689 (for example: 700-People's Daily＝＞700-3689)

People's China => 3616

Beihai Park＝＞4716

Department Store＝＞7612

When different words produce the same code in the system, a serial number is added to the end of the string. For example, when a character having the same numerical code as the code "7612" of "department store" exists in the system, such as "department store 1", a serial number is thus added to generate code "76121".

Another option is that when the user inputs a character to determine the tone-based simple code, the system can extract the simple code corresponding to the input character according to predetermined rules for generating the tone-based simple code, and will extract A simple code to display to the user. The Chinese character is an ideographic character, which is different from a pictophonetic character in that the system must clarify the mapping information between the tone and the number of strokes (or the number of component characters), as well as the number of the character number.

The present invention proposes a method for mapping Chinese characters to keys of a keypad according to the pitch and complexity of the characters. Because five tones are assigned to two keys, this is a characteristic of Chinese characters, so in order to be more convenient for users, the intuitive consideration is to make the layout of the current keypad 2 columns and 5 rows. For example, keys [1] and [2] are assigned to the first row of the keypad, keys [3] and [4] are assigned to the second row of the keypad, keys [5] and [6] are assigned to the first row of the keypad Three lines, keys [7] and [8] are assigned to the fourth line, keys [9] and [10] are assigned to the fifth line, keys [*] and [#] are assigned to the sixth line. The first through fourth tones and no tones are assigned to the two keys on each row of the keypad, and the system determines whether a given character corresponds to a key of the first or second column according to the complexity of the character. Figure 5-3 shows the layout of this 2*6 keypad. In this case, with each tone assigned to two keys on each row of the keypad, the system follows the complex row of characters to determine whether a given character corresponds to a key of the first or second column.

If multiple methods are used instead of one standard, the keypad keys assigned to the tones vary, and thus the resulting code values vary. Thus the codes generated in one specific method (for example, the codes produced by the 3*4 keypad in the present invention) and the codes produced in another method (for example, the codes produced by the 2*6 keypad in the present invention) are required conversion between. This conversion can be performed in the terminal's server or client software. In either case, a conversion is performed at each system (server or client terminal), and with knowledge about the method applied in the system it is possible to re-transform to the desired code. For example, when the code value desired by the system is obtained by method 2, and the code value of "People's Daily" is input according to method 1, the code value can be determined by method 2.

To generate a code from "Department Store" instead of "Department Store", enter "Department Store" together using the special function keys to make "Department Store" bold and generate the code "76" for "Department Store". Moreover, when the user wants to generate a code from a part of a character (for example, "Hu" in a product) (in order to avoid overlapping of the same code, etc.), the system marks the characters of that character in bold, thereby generating a code. In this case, the simple code for "Department Store" ("Albino Company" marked in bold) is not "7612" but "7312".

The usual method of inputting Chinese characters is to write the pronunciation of Chinese characters in English, and change it into convertible Chinese characters according to the selection of the "Chinese character conversion key", so that the user can select the corresponding Chinese characters.

In Chinese, the complete code is determined according to the English pronunciation of Chinese. And, when the same pronunciation has a plurality of words, determine the complete code with the code combination according to the priority of the target character in English pronunciation, Chinese character conversion key and the same pronunciation character. In the example of the present invention, the Chinese character conversion key on the keypad is the key [*] in Figures 5-2 and 5-3. If there is no specific description about the input method in English, it should be understood that the present invention uses an existing input method.

In the present invention, it is necessary to provide "specific function keys" for Chinese simple naming. That is to say, the user inputs English, selects the Chinese character conversion key, to select the desired Chinese character, and then inputs a specific function key (hereinafter referred to as "simple code (SC) key") for Chinese simple naming to sequentially The corresponding character and its constituent characters are displayed, from which the user selects the constituent characters, for generating a simple code. In the example of the present invention, the simple code key is the key [#].

According to the above example, when the user enters "goods" in "department store" and selects the simple code key, the system displays "goods" and its constituent characters "hua" and "tool" in sequence. If the user selects "化", the system will display "化" in the item in bold, thereby recognizing that the corresponding simple code is 3. Wherein the simple code "3" of "goods" represented in bold is stored in the system for later use, or interpreted according to characters.

Regarding Chinese, for the naming of codes, a Chinese dictionary needs to be provided in the entire system (client or server). That is, when a user enters a named character (ie, a word or phrase corresponding to a simple code), the user refers to the character's pitch and stroke (or the number of constituent characters) to look up the named character in the dictionary, thereby assigning the named The characters are mapped to array codes. Assume that the dictionary includes tones and stroke numbers (or the number of constituent characters), which are used to map Chinese characters to numbers on the keypad. A user or system operator must be able to add words not listed in the dictionary, as well as store information such as the pronunciation of Chinese characters. If there is no Chinese dictionary in the entire system, the user is required to input not only words as named characters, but also mapping information such as the pitch of the characters, or numerical codes corresponding to the characters.

For Chinese characters, the advantage of generating simple characters based on the tone is that each character is not generated according to English pronunciation, and each character intuitively corresponds to each numeric code. Typically, Chinese company names and city names include a fixed number of characters and the length of the tone-based code is equal to the number of characters (ie, the number of tones). Therefore, it is advantageous that the length of the simple code is fixed, and it is usable even when there are no English letter markings on the keypad.

The same applies to every language that has tones, such as Thai or Burmese. All Thai languages have tones, which are classified into five categories, namely, flat tones and first to fourth tones. Thus, each tone can be mapped to a key on the keyboard, as is the case in Chinese. As in Chinese, when mapping a tone to two keys on the keyboard, the system must determine which of the two keys should be assigned to the tone according to the number of strokes or the number of constituent characters. For example, in Thai, there are two types of vowels that are combined with syllables, namely, simple vowels and long vowels, simple vowels are mapped to lower-numbered keys, and long vowels are mapped to higher-numbered vowels sound.

There are also two types of tones; one is called "visible tones", which are marked with diacritics, and the other is called "invisible tones", which are not marked with diacritics. Five intangible tones can be represented according to the type of consonant, the relative length of the vowel, and the presence of the final consonant. Consonants in Thai include nine middle consonants, ten high consonants and twenty-three low consonants. Depending on the consonant, even tangible consonants of the same diacritic are different from one another. Therefore, four vowels marked with one of the four diacritics and one vowel not marked with a diacritic are mapped to two keys of the keypad respectively, and depending on whether the vowel to be combined is a simple vowel or a Long vowels to identify simple codes. This simple code is specifically called "diacritic-based simple code".

Burmese has three tones, namely, first, second and third tones. All three tones are marked using diacritics. So each of the three tones can be mapped to three of the keys [1] to [9]. For example, the syllable of the first tone maps to the three keys of the first row of keys, namely keys [1], [2] and [3]. The symbols of the same tone are divided into three parts: one is the syllable without the final consonant (for example, consonant + vowel), the other is the syllable without the initial consonant but has the final consonant (for example, vowel + consonant), and the other is the existing The initial consonant has a syllable of the final consonant (for example, consonant + vowel + consonant). For example, a syllable of the first tone is mapped to any of keys [1], [2], and [3], and if a syllable includes "consonant + vowel" but no final consonant, it is associated with key [1] . All syllables in Burmese have diacritics, and the rules for constructing syllables are generally understandable. Therefore, there is an advantage that a simple symbol-based code for each word can be automatically generated according to the rules.

6.3 Unique simple code

If the client terminal is responsible for decoding the simple code (that is, when the client terminal has a specific word or phrase and its simple code value), the word or phrase corresponding to the input simple code is transmitted to the server. When the server needs the simple code according to future use, the client terminal sends the simple code itself (ie, the displayed number) to the server, which then decodes the simple code. Therefore, simple codes can be decoded both at the client terminal and at the server.

For a single code of multiple words or phrases, there are many words or phrases corresponding to the same simple code. This ambiguity between simple codes in CIM is conveniently referred to as "secondary ambiguity". In this case, although the system could add a serial number to the simple code in order to store a unique code value, a second ambiguity still occurs because the user normally uses the simple code corresponding to a particular word or phrase. Of course, the system must recommend such words or phrases to the user according to the priority of use. For the same simple code with different words or phrases, the system adds a serial number to the simple code according to the frequency of use of the word or phrase, and uses the serial number as a priority when recommending the word or phrase to the user. Here, the system does not need to add serial numbers to simple codes, and information about priority can be separated.

具有较高的频率，则系统向该单词赋予优先权，并且为 规定简单代码“91961”，为 规定简单代码“91962”。为简便起见，这种带有序列号的简单代码称为“唯一简单代码”，而不具有序列号的重叠简单代码称为“简单代码”，二者都称为“简单代码”。For example, when and When all the simple codes are "9196" as the syllable-based initial code, the system adds serial numbers to the simple codes according to the usage frequency of each word, and uses the serial numbers as a priority for recommending words to users. if

has a higher frequency, the system gives priority to that word, and for Specifies the simple code "91961", for Specify the simple code "91962". For brevity, such a simple code with a serial number is called a "unique simple code", an overlapping simple code without a serial number is called a "simple code", and both are called a "simple code".

6.4 Use of simple code

Here's an example of a simple code (e.g. a syllable-based initial code) assigned to different city names, which is useful in railway information systems and the like:

和

具有相同的基于音节的初始代码，所以系统向简单代码添加序列号，如 和

如果用户仅仅向系统发送“78”，系统正确执行反馈(例如，提供一列 和 或者以声音通知该列)，以致于用户既可以选择 又可以选择

一旦最初用户输入“781”，则系统认为简单代码就是

because,

and

have the same syllable-based initial code, so the system adds serial numbers to simple codes, such as and

If the user simply sends "78" to the system, the system correctly performs the feedback (e.g., provides a list of and or an audible notification for the column) so that the user can either choose can also choose

Once the initial user enters "781", the system assumes that the simple code is

而非简单代码“78”，则客户终端将简单代码解释为

并且将它发送给服务器。在服务器根据将来的使用需要简单代码而客户终端能够对简单代码解码时，客户终端必须仅仅将简单代码发送给服务器。If the server expects the word

instead of the simple code "78", the client terminal interprets the simple code as

and send it to the server. When the server needs the simple code according to future use and the client terminal can decode the simple code, the client terminal has to transmit only the simple code to the server.

Simple codes for bank codes are given below, which are very useful in ATMs and various financial information systems:

Obviously, the predefined simple codes can be applied to the input of words or phrases in such a manner: the user inputs the predefined simple codes, and then the client (terminal) provides the decoded simple codes to the user. This method is called "shortcut input method (SIM)" and will be described later together with "simultaneous input method (CIM)".

Whether the frequency of use is marked as high when using the criteria. For example, when the user selects the

Then the existing priority will be changed automatically. The system asks the user to confirm the change of priority according to the given options.

6.6 Automatic designation of simple codes and marking characters related to simple codes in bold

In addition to the fully correlated simple codes, the consonant-related simple codes, the syllable-based initial codes, and the word-based initial codes follow their production rules. Therefore, when the generation rule of the simple code is stipulated, the user inputs a specific word or phrase, so as to assign a simple code to the word or phrase, and then automatically extracts the corresponding simple code and stores it in the system. Here, characters related to simple codes are marked in bold for the convenience of users. For English, simple codes associated with characters are highlighted as uppercase characters.

The prior art literature discloses "SIM" and "Express/Full CIM". Simple codes for quick entry can be defined in the system and then changed by the user. The user can further specify a simple code for another word or phrase.

然后在简单代码创建模式下输入“9196”。Simple codes specifying new words or phrases may follow defined rules for generating simple codes, such as fully correlated simple, partially correlated simple codes, syllable-based initial codes, as disclosed in prior art literature. To generate a simple code for "dance with the wolf" from a word-based initial code, for example, the user must enter "dance with the wolf" and then enter "3983" as a word-based initial code in the simple code creation mode. Likewise, in order to generate simple code, the user enters

Then enter "9196" in the simple code creation mode.

的简单代码。If the user can make the system remember the desired type of simple code, the simple code can be automatically assigned to a specific word or phrase, thereby eliminating the trouble of entering the desired type of code. For example, when the user sets the type of desired simple code in the system to syllable-based initial code, and simply enters then the system automatically assigns "9196" as the

simple code for .

It has been stated that English-related code can be capitalized and marked in bold. In this regard, when the user specifies in advance the use of capital letters in the simple code and enters "DaTe ToNight", the system automatically determines the simple code as "3886" corresponding to the capital letter "DTTN". Otherwise, if the user enters something like "ToNight Show", the system automatically determines the simple code as "8679" which corresponds to the capital letter "TNSW".

6.7 SIM and CIM using simple codes of words or phrases

As the user enters the simple code (unless specifically stated otherwise, the simple code includes the initial code, which is a special form of the simple code), the system (client system or server system) can recognize the simple code as its corresponding word or phrase. Therefore, it is obvious that when the system recognizes a specific simple code as a corresponding word or phrase, and displays the word or phrase, the user can use the displayed word or phrase in inputting a new word.

In the character input method used in other countries, the character input mode is implemented in such a way that the terminal (client system) stores an index of "completely related simple codes" assigned word by word, and displays the codes assigned by the user according to the word priority. The corresponding word of a given code entered in the right order, thus allowing the user to determine the target word. More information can refer to Internet sites, http://www.tegic.com and http://www.zicorp.com are recommended. In the following, this method is referred to as "full-associated SIM" or "foreign method".

A comparison between the methods of Tegic Company and Zi Company and the method of keyboard input characters according to the prior art documents of the present application shows that the character input method of the present application assigns a unique code to each character and allows the input of objects with complete codes characters or target words (phrases), while the above-mentioned foreign method assigns a complete correlation simple code to each word, and allows input of target characters using the simple codes.

The foreign approach has the following disadvantages: (1) it allows exclusive entry of predefined words, since codes are assigned to each word; (2) when different words share a code, it is more difficult to enter less frequently used words , because the user has the trouble of selecting and confirming the target word by using the switching key or the moving key; (3) during inputting a word, words other than the target word may temporarily appear; and (4) the realization of the system requires a large memory capacity and higher cost.

Simple codes (ie, partially related simple codes or fully related simple codes) can be assigned to commonly used words or phrases, and when entering a target word or phrase, the simple codes are used. Of course, commonly used words or phrases can be predefined in the system and provided to the user, or completely specified by the user. Alternatively, the user should be allowed to change the simple code predefined in the system at will. Advantageously, the user is allowed to specify a simple code, since the user will gain knowledge of the simple code for a particular commonly used word or phrase.

For the sake of simplicity, in the present invention, the method of using simple codes (comprising partial relevant simple codes, complete relevant simple codes and initial codes) to input target characters or phrases is referred to as "Shortcut Input Method (SIM)" and uses complete code input The method of target characters is called "full input method (FIM)". As will be described later, it is also possible to use a combination of SIM and FIM, which is called "Express/Complete Simultaneous Input Method (Express CIM)" or simply "Concurrent Input Method (CIM)".

Even if a unique code is assigned to each character and used to input the target character, ambiguity will arise due to repeated selection in FIM. For simplicity, this ambiguity is called "first ambiguity" or "character ambiguity". In contrast, ambiguity occurs between different words that share the same simple code in methods such as the foreign method (i.e., SIM), where a code is assigned to each word and used to enter target word. For simplicity, this ambiguity is called "second ambiguity" or "word (phrase) ambiguity". The term "ambiguity" refers here to the first ambiguity.

There are two situations: one is that the system first interprets a specific input value as a simple code (that is, the first step of using SIM, or using a shortcut input method as a basic input method), and does not use any corresponding input value. simple code, which is then recognized by the system as a complete code (i.e., using the second step of FIM); the other is that the system first checks whether a particular input value constitutes a complete code (i.e., using the first step of FIM, or would use the full input mode is used as the basic input method), if the input value does not constitute a complete code, then the system recognizes the input value as a simple code (ie, using the second step of SIM). The first interpretation of the input value as a simple code is applied to the "shortcut input mode" which is the basic input mode, and the first interpretation of the input value as a full code is applied to the "full input mode" which is the basic input mode. Preferably, those modes that usually input commonly used words or phrases should first apply SIM (i.e., apply the shortcut input mode as the basic input mode), and those modes that do not usually input commonly used words or phrases should first apply FIM (i.e., use the shortcut input mode as the basic input mode). input mode applies full input mode).

识别为 这适用于诸如

或者 之类的单词，在其中，第二和第三音节(字母)的初始辅音对应于相同的按键。另一方面，在指定为基本输入方法的快捷输入方法中，系统首先将输入值解释为简单代码，并错误地将输入的完全代码识别为不想要的单词。这种CIM中简单代码和完全代码之间的多义性称为“第三多义性”。In the full input mode, designated as the basic input mode, the system first interprets the input value as a full code and incorrectly identifies the input code as an unwanted word. For example, in Figure 4-2, when BRSM is applied as SIM, the word The simple code for is recognized as "877" (using a syllable-based initial code) and the system first interprets the entered simple code "877" as a full code, thereby interpreting

identified as This works for things like

or Words such as , in which the initial consonants of the second and third syllables (letters) correspond to the same key. On the other hand, in the shortcut input method designated as the basic input method, the system first interprets the input value as a simple code, and mistakenly recognizes the entered full code as an unwanted word. The ambiguity between simple codes and complete codes in this CIM is called "third ambiguity".

As usual, the third ambiguity can be overcome using the toggle or movement keys for selecting the target word. Another optional method is: in a word unit, before inputting the input value that causes the third ambiguity, the input mode is switched between the full input mode and the shortcut input mode. This is similar to the method described in the prior art literature of the present application, in which, the Control (ie, Hiragana/Katakana Conversion Control) to enter Katakana in Hiragana mode, or enter Hiragana in Katakana mode. For example, in the full input mode designated as the basic input mode, the system initially recognizes the input value after selecting the "quick/full" control as a simple code, and the reference index provides the user with the target word corresponding to the input value. Likewise, in the shortcut input mode designated as the basic input mode, the system initially recognizes the input value after selecting the "quick/full" control as a full code. The "Quick/Full" control can be set to select before or after the target word is entered, but in the case of this control it is more convenient to set the control to select after the target word.

In CIM, the system can determine whether an input value is a full code or a simple code. This decision can preferably be made using the index in the word unit, in order to dispel the first ambiguity as described above, or, as will be described later, during the entry of the input value.

When applying CIM in the full input mode designated as the basic input mode, the system checks each input code input by input (i.e., value by value) whether it constitutes a full code, and when it recognizes that the input code value does not When the complete code is formed, the input value is determined as a simple code, and the word or phrase corresponding to the simple code is sent to the user with reference to the index, thereby improving the efficiency of the CIM. Likewise, in applying CIM to the shortcut input mode specified as the basic input mode, the system checks that each input code value is equal to the input value listed in the index, and when no word matches the input value, the code value is entered Fully coded for identification as FIM. This means that the third ambiguity can be eliminated at the beginning of using the FIM rules. It can also be applied to character input methods that are not disclosed as FIM in prior art documents. Description will now be given in the form of an example below with respect to FIM (basic iterative selection method and part-whole selection method) disclosed in prior art documents.

For example, for Korean, the second and third input values entered by the full code when using BRSM should be consonants, which is illustrated in Figure 4-2. If this rule is violated, the input value is treated as simple code. When dealing with tight consonants through combinations of flat consonants, the relevant criteria apply in all cases where BRSM is used.

In all languages, when the PWSM is used as a FIM, two input values correspond to one character, and one input value is constrained relative to the other. In the case of English, for example as shown in Fig. 1-1, it is assumed that only horizontal line combination (HSC) can be applied to English, instead of applying PWSM to input digits. If the buttons [1], [2] and [3] of the first row are used as the first input value (first button) corresponding to a character, the second input value can correspond to the button [1] of the first row ], [2] and [3]. Likewise, when the button [4], [5] or [6] of the second row is selected after [2]+[1], the next value to constitute the complete code is the button [4], [ 5] and one of [6]. When the input value violates this rule, the system regards the input value as a simple code and recommends words corresponding to the simple code to the user. When using the PWSM in Figure 4-2, the fully encoded subsequent keystrokes entered in response to the first keystroke [1] are simply keystrokes [1] or [2]. If this rule is violated, the system considers the input value to be a simple code rather than a complete code, and the reference index recommends the target word corresponding to the input value to the user. If shown in Figure 1-3, four characters P, Q, R and S are assigned to the key [7]. Then one of the four characters can be assigned to a grid cell that constitutes a vertically adjacent combination (VAC) in the PWSM. When key [7] is selected in this case, so as to form a complete code of a character, the next key may be [7], [8] or [9] of the third row, or key [4]. If this rule is violated, the input value is treated as simple code. The same applies to all languages if using PWSMs like those disclosed in prior art documents.

Figure 4-5 shows that a flat consonant is assigned to each key. Therefore, when the syllable-based initial codes commonly used in Korean are used as simple codes, the third ambiguity can be avoided when both SIM and FIM are used. That is to say, when using the user input syllable-based initial code in the CIM, it is difficult to form a complete code from the second input (when input values for aspirated and tense consonants are entered through the CPM). The system therefore refers to the index of simple codes and recommends the correct word to the user in order of priority. The same principle applies to the entry of complete codes in the CIM.

As described above, the core of the present invention lies in being able to determine during character input whether the input value is a simple code or a full code when using a CIM. The same principle can be applied to the case where the system uses the prior art document and the FIM of the present invention, or other FIMs. Specifically, as described in the above example, the FIM of the present application is advantageous in that during input it can be checked whether the input value forms a complete code in the FIM.

Furthermore, simple codes or full codes can be obtained either in the client or in the server, as described in the prior art literature and in this application. When looking up the target word in the index so as to overcome the first ambiguity (character ambiguity) in the prior art literature, a kind of situation is that the system refers to the client's index in the first stage, then in the second stage the server's The index should be used for simple code or full code interpretation, alternatively, the system can refer to the server's index in the first stage, and then refer to the client's index in the second stage. Moreover, when the system interprets the input value as a simple code in the first phase referring to the client's index and then in the second phase referring to the server's index but no simple code is found for the input value, it interprets the input value as exactly Code: Refer to the client's index in the first stage, otherwise refer to the server's index in the second stage. Another option is for the system to interpret the input values as simple codes in a first stage by referring to both the client's index and the server's index, and then allow the user to select the target word. Any similar variations on interpretation method (simple code or full code) and interpretation location (client or server) are possible. That is, there are various combinations of input methods (simple code or full code) and interpretation locations (client or server).

Simultaneous use of SIM and FIM has the following advantages: (1) when using FIM, the user is allowed to select almost all words including words that do not exist in the dictionary and predetermined words; (2) the user can specify simple codes (not partially related simple codes) is the complete relative simple code); (3) the user can specify part of the relative simple code, so as to significantly reduce the number of keystrokes entered; the word-based initial code is assigned to phrases and words. In contrast, the foreign approach consults the indices of all input words word by word, and thus must use codes that are perfectly related to simple codes to minimize the probability of the same code being assigned to a different word.

In addition, the system has an "index" that includes a particular commonly used word or phrase and the code value for that word or phrase, which requires less memory capacity than foreign methods. This index is like an "index" in the system that includes correct or incorrect ambiguous words to facilitate disambiguation.

In each language, consonants have a word-specific pronunciation value, and methods for extracting acronyms from consonants are widely used. Taking English as an example, the military term "captain" is abbreviated as "CPT", which includes consonants that have the sound value of "captain", "sergeant" as "SGT", "staffsergeant" as "SSG", and "sergeant first class" as "SFC". Although "captain" and "private" have two syllables, consonants extracted as abbreviations are regarded as denoting consonants of the respective syllables. So, the simple code for "captain" is "278" which is related to "CPT".

The system of the present invention allows assigning partial correlation codes by syllable for commonly used words or phrases and uses SIM, so the present invention makes sense in the sense that entering characters requires less labor. A syllable is defined phonetically as a "mental entity". Consonants have the sound value of syllables. It is not possible to extract "AAI" to analyze "captain" without vowel extraction. However, "captain" can be analyzed by extracting "CPTN" or "CPT" according to the consonants. It has been reported that any English sentence can be analyzed in terms of constituent consonants instead of vowels in each word. That is to say, the joint use of some relative simple codes with each consonant constituting a syllable allows the user to apply the SIM naturally and more conveniently.

In particular, simple codes can be used on the basis of acronyms, since acronyms are widely used in English-speaking countries, for example, listed company names are often represented with abbreviations.

Allowing the user to specify the type of simple codes (ie, partially related simple codes and partially related simple codes) for specific words or phrases has the advantage of being easy to remember code values for commonly used words or phrases. Also, if the user only needs to use part of the words or phrases, each word or phrase is assigned a simple code (eg, 1, 2, 3, etc.) rather than the characters of the word or phrase.

6.8 Grouping of simple codes/corresponding words or phrases, and designation of search ranges

There are several cases where overlap occurs when specifying simple codes for multiple words or phrases. Ambiguity between simple codes (ie, second ambiguity) can be reduced by grouping words or phrases corresponding to the simple codes and searching for simple codes only for a particular group of words or phrases. A word or phrase need not belong to only one group, it can be included in multiple groups.

For example, words or phrases after simple naming are divided into categories such as company names, city names, common words (phrases), and the group of common words (or phrases) can be subdivided into categories such as society and politics. Although the present embodiment provides two-level and three-type grouping, it may be three-level, four-level or more tree-type grouping. If the user (system) limits the search scope of the simple code to a group of company names, the system searches the company name class for the named word or phrase corresponding to the specific input simple code, thus reducing the second ambiguity. Likewise, when the user limits the search scope to a common word or phrase group, the system searches for the named word or phrase in the common word or phrase group and all its subordinate groups. If the user restricts the search to the social category of the common word or phrase group, the system searches the social category and all its subordinate groups for the named word or phrase.

6.9 Use of Exchange Server

Interpretation of simple codes can be performed in the client or server. Alternatively, an exchange server dedicated to interpreting simple codes (including complete codes in some cases) can be used to provide the client terminal or another server with the word or phrase corresponding to the simple code. As shown in Figure 6-1, in the figure, the client terminal first decodes the simple code, if the word or phrase corresponding to the input simple code cannot be explained, then the exchange server interprets the word or phrase corresponding to the input simple code in the second stage word or phrase. Once the interpretation fails, each server can interpret the word or phrase corresponding to the input simple code in the third stage. The third simple code decoding server (referred to as "the third server" for brevity) is a server installed with an application program using the input simple code or its corresponding word or phrase.

With the exchange server, the user enters the simple code even when the third server requires a word or phrase instead of the simple code. Even if the third server does not store the simple code and the word or phrase corresponding to the simple code, the exchange server interprets the simple code input by the user to transmit the corresponding word or phrase to the third server.

When inputting a simple code, the system queries the word or phrase corresponding to the simple code in the index, and inputs the word or phrase one by one (that is, one value by one value), or in units of words (that is, , word by word) feedback to the client terminal or each server.

6.10 Distinction of Word Units

The term "word unit" as used herein refers to the length of a word from the beginning to the end of a word. Word units are determined by a combination of all factors used to distinguish words, such as prefixes, spaces, mode transitions, carriage returns, etc. For example, the input of a word is determined through prefix-end, space-space, space-pattern conversion, and so on. Feedback in units of words can be performed through programming languages that currently support the web environment.

6.11 Download of simple codes and corresponding words or phrases

The client can also download simple codes and words or phrases corresponding to the simple codes from the server without directly storing the simple codes and their corresponding words or phrases.

Downloading may be performed in units of words or phrases, or in the above-mentioned groups of words or phrases (ie, grouping in a tree structure). If a group is selected, the client can download its subordinate groups as well as the selected group. During downloading, the client terminal can assign the word or phrase and its subordinate groups belonging to the corresponding group to a group designated by the user in a tree structure of words or phrases set by the server. In charge of this work is the exchange server whose main function is to decode simple codes.

7. Input of symbols

As stated in the prior art literature, characters are assigned in order of native language, numerals and English letters, where characters are assigned in "Order of Proximity to BLE (OPBLE)", while native language and numerals are selected in BRSM in order of proximity to BLE . Likewise, numbers and English letters assigned to specific keys and native languages can be entered through SCPM.

Furthermore, the present invention provides a method of efficiently entering various symbols that are not marked on the keypad (ie, using a hidden control processing method), whereas in prior art documents, these symbols are marked on the keys.

That is, the present invention assigns a "symbol control" to the appropriate one of the grid cells, and is entered by a combination of a symbol control and a key associated with a particular symbol (i.e., another key than the control key). symbol. Here, the key associated with point "." is key [5], because "ロ" is associated with first syllable of (Korean name for dot) related.

(代表性字符)，

(第二)，符号(第三)，...。例如，当控制设置为要在代表性字符之前选择时，“.”的输入这样给出：ロ＝{符号}+ロ＝[*]+[*]+[5]，或者当控制设置为要在代表性字符字后选择时，ロ＝ロ+{符号}＝[5]+[*]+[*]。如果符号控制安排在能够使用按键[*]的连续三次击键来选择的网格单元，则在上面的示例中添加依次选择按键[*]。For example, as described in the prior art literature, symbol controls can be arranged at grid cell positions that can be selected by two consecutive keystrokes of the key [*] in the Korean example (FIG. 4-2). That is, the relationship between a representative character and its successor is given by:

(representative characters),

(second), symbol(third), .... For example, when the control is set to be selected before the representative character, the input of "." is given like this: ロ={symbol}+ロ=[*]+[*]+[5], or when the control is set to be When selecting after representative character word, ロ=ロ+{symbol}=[5]+[*]+[*]. If the symbol controls are arranged at a grid cell that can be selected using three consecutive keystrokes of the key [*], add the sequential selection key [*] in the above example.

Using only one symbol control, even if symbols are assigned to each of the 10 number keys, only 10 symbols can be entered. For example, the assignment of symbols to each key is given below:

Key [1]: symbol "?" ( related in shape to "?");

与

(意思是朝鲜语的“感叹号”)的第一音节 相关)；Key [2]: symbol "!" (

and

(meaning "exclamation point" in Korean) first syllable related);

Key [3]: symbol "$"(" "and" The first syllable of " (meaning "dollar" in Korean)" "related);

Key [4]: ...

”与 (意思是朝鲜语的“点”)的第一音节 相关)；Key [5]: symbol "."("

"and (meaning "dot" in Korean) the first syllable of related);

Key [6]: symbol "*"(" "and" The first syllable of " (meaning "asterisk" in Korean)" "related);

Key [7]: symbol ","(" "and" " (meaning "comma" in Korean) the first syllable" "related);

”与“

”(意思是朝鲜语的“引号”)的第一音节“

”相关)；Key [8]: symbol """("

"and"

The first syllable of " (meaning "quotation mark" in Korean)"

"related);

”在形状上与 相关)；和Key [9]: symbol "~" (vowel "

” in shape with related); and

Key [0]: symbol "@" (the number "0" is related to "@" in shape).

As described above, various symbols can be input by combination of symbol control and keys other than the symbol. The symbols assigned to each key take into account the relationship between the name or shape of the symbol in the native language and the characters on the key, or the relationship between the English name or shape of the symbol and the English letter on the key, or the relationship between the name or shape and the number on the key names and the relationships between shapes. This consideration is not necessarily limited to the cases mentioned above, and can be reset by the user according to his preference.

”的按键[1]相关，因为比问号“？”更主要的点“.”(朝鲜语名称为“ ”)带有作为“ ”的第一音节“

”的初始辅音的“ロ”。Thus, these frequently used symbols can be treated as if they were consecutive characters belonging to the numeric keys that tend to remind people of their respective symbols. In the example above, given the similarity in shape, the question mark "?" (Korean name for " ") with the

The keystrokes of "[1] are more relevant than the question mark "? "The more important point "." (Korean name is " ") with as " the first syllable of ""

"ロ" of the initial consonant of ".

Likewise, the assignment of a symbol to each key may be associated with an English name/shape or a numerical name/shape. The following examples are suitable for use in conjunction with the native language.

Key [1]: symbol "?" (the character "q" is related to the first character of "Question mark");

Key [2]: symbol "," (the character "c" is related to the first character of "Comma");

Key [3]: symbol "." (character "d" is related to the first character of "Dot");

Key [4]: symbol "!" ("i" is related to "!" in shape);

Key [5]: ...

Key [6]: ...

Key [7]: symbol "/" ("s" is related to the first character of "Slash");

Key [8]: symbol ":" (number "8" is related to ":" in shape);

Button [9]: symbol "!" ("x" is related to the pronunciation of "eXclamation mark");

Key [0]: symbol "@" (number "0" is related to "@" in shape).

An advantage of assigning symbols primarily in English is that this assignment can be applied to non-English-speaking countries where the native language associated with English is marked on the keypad. Using a similarity in shape between the colon ":" and the number "8" is generally acceptable regardless of language. Likewise, if not applicable to the above example, when assigning "," to the key [9], the similarity in shape between the comma "," and the number "9" may be considered.

Symbol controls can be assigned to appropriate keys. For English, unless another control is assigned to the key [*] in Figure 1-1, the symbol control can be selected with a single keystroke of the key [*] (the symbol control is arranged in the basic grid cell of the key [*] s position). For native European languages that include affixed characters with affixes, the symbol control can be arranged at the position of the basic grid cell of the key [0] or [#]. Since the symbol control is assigned to the key[0], it is desirable not to assign the symbol "@" to the key[0].

If the control is set to be selected after the representative character, and the symbol control is assigned to the key [*], then entering a colon ":" in Figure 1-1 would give ":=[8]+{symbol}=[ 8]+[*]".

As can be seen from the above example, where each key has the meaning of an associated symbol and the symbol control is assigned to one grid cell controlling the key, only 10 symbols can be entered. Since it is related to "slash" in the above example, the key labeled "s" can be used to specify any symbol, such as slash, semicolon, period, etc. Since the key marked with "d" is related to "dot", the key of "i" is used to designate the "exclamation mark" in view of the similarity in shape.

的含义分派给标记有“ロ”的按键)相关的按键，以便应付在形状上相似的逗号“，”，如同它是“dot”的相继字符。More symbols can thus be entered by the CPM using multiple symbol controls (eg, symbol control 1, symbol control 2, . . . ). For example, the meaning of dot is assigned to "d" (or

The meaning of is assigned to the key marked with "ロ") related key, so as to cope with the comma "," which is similar in shape, as if it is the successive character of "dot".

As shown in Figure 7-2, where a symbol control is added to Figure 4-5, when the control key is set to [*] and the control is set to be selected after a representative character is entered, the input thus gives "dot(. )=[3]+{symbol 1}=[3]+[*]+[*]+[*]", and "comma(,)=[3]+{symbol 2}=[3]+[* ]+[*]+[*]+[*]". From the point of view of the Chained Sequential Control Processing Method (SCPM), the input is given as: comma(,)=dot+{successor}=dot+[*]=[3]+[*]+[*]+[*] +[*]. When an aspirated consonant is not entered by the CPM (i.e., assuming no aspirated consonant on the control key), two keystrokes of the key [*] are used to select "Symbol Control 1" (i.e., the skip control processing method is applied). Likewise, a colon and a semicolon, which are similar in shape to each other, are regarded as consecutive characters assigned to the same key, and are input by the CPM. The same can be applied to other symbols.

Even when using two symbolic controls, namely, "Symbol Control 1" and "Symbol Control 2", the system has to assign a symbolic meaning to each key and remember it, so the system has limitations in the input of numeric symbols. Therefore, group symbols into: for example dot and comma, or colon and semicolon, and assign multiple symbol controls so that a larger number of symbols can be entered.

It is preferable that the user selectively sets symbol groups. The present invention proposes a general example of symbol grouping. First, the variants of dot "." can be grouped like this, for example, dot ".", comma ",", colon ":", semicolon ";", quotation mark """, question mark "? ", exclamation mark "! " etc. This group includes symbols in point shape, ie, "zero-dimensional" symbols. Here, the question mark "? " and the exclamation mark "! " is both zero-dimensional and one-dimensional, and thus includes the group of symbols in zero dimension (point shape). Additional priority for determining this group takes into account the frequency of use as described in the prior art literature. Preferably, in The user can specify this consideration when determining priority. When a large number of symbols are to be treated as consecutive symbols, it is recommended that the control be set to be selected after the representative character. When the control key is pressed repeatedly, the display window with The terminal can display successive symbol changes.

Allows the user to selectively associate dot-shaped (zero-dimensional) symbols with specific keys. For example, the dot ".", which is the most commonly used and representative symbol of this group, is considered to belong to successive symbols of the key [3] including the "d" of "dot". If the control is applied after entering a representative character using the symbolic control key designated as key [*] in Figure 7-1 added to Figure 1-1, the input is given by : point (.)=[3]+[*], comma (,)=[3]+[*]+[*], colon (:)=[3]+[*]+[*]+[* ], semicolon (;)=[3]+[*]+[*]+[*]+[*], and so on. Because they are both in zero-dimensional form, point-shaped symbols can be seen as belonging to and related to key[0]. Another option is, considering that the dots "." are the most basic form, they can be seen as consecutive symbols belonging to the key [1].

的按键[1]或者按键[5]的相继符号。Next, linear (i.e., one-dimensional) symbols are grouped like this, for example, slash "/", hat mark "^", question mark "?", exclamation mark "!", parenthesis 1 "(", parenthesis 2") ", Angle Brackets 1 "<" Angle Brackets 2 ">", Square Brackets 1 "[", Square Brackets 2 "[", Tilde "~", Negative Sign "-", Arrow 1 "←", Arrow 2"→" and so on. The additional priority of the group is determined taking into account the frequency of use described in the prior art documents, and said priority relates to the correct assignment of successive characters of a particular key. For example, line symbols are considered to belong to the

The successive symbols of the button [1] or the button [5].

”，cloverl“

”，空三角形1“ ”空三角形2“

”，空三角形3“

”，...，实三角形1“”，...，

等等。这一组的附加优先权的确定也可以考虑已有技术文献所述的使用频率，并且所述附加优先权通过使用适当的方法来与特定按键的相继字符相关。必须的是，这一组的符号应该与除与零维和一维符号相关的按键之外的按键相关。Line-related (i.e., two-dimensional) symbols are grouped such as, for example, at "@", ampersand "&", asterisk "*", sharp "#", dollar sign "$", won "W+=" Yen "", ..., Heart 1" ",Heart 2"

", cloverl"

", Empty Triangle 1" "empty triangle 2"

", empty triangle 3"

", ..., real triangle 1 "", ...,

etc. The determination of this set of additional priorities can also take into account the frequency of use described in the prior art literature and is related by using an appropriate method to the successive characters of a particular key. It is imperative that the symbols of this group should be associated with keys other than those associated with zero-dimensional and one-dimensional symbols.

The symbols are divided into three groups, namely, zero-dimensional symbol group, one-dimensional symbol group and two-dimensional symbol group. Multiple keystrokes are required to control the keys. In order to overcome this problem, the three groups are subdivided into the following subgroups.

，...)的单独符号组，其中，符号也看作属于适当按键的相继字符。独立符号组的符号可以排除在前面的符号组之外。同样可以适用其它情形。First, two-dimensional symbols are subdivided into groups of linearly related symbols (i.e., *, #, %, ...) and a second group of symbols in the form of simple closed curves (i.e., , ...). In addition, include graphics (ie,

, ...), where the symbols are also considered as consecutive characters belonging to the appropriate key. Symbols of independent symbol groups can be excluded from preceding symbol groups. Other situations are equally applicable.

，等等，这些符号也看作属于适当按键的相继字符。A separate group of symbols includes one-dimensional and two-dimensional symbols for mathematical relations, such as +, -, *, /, square root "√", sigma "∑", integral "∫" and so on. These symbols are also considered as consecutive characters belonging to the appropriate key. Another separate group of symbols includes directional symbols such as →, ←, ↑, ↓,

, etc., these symbols are also considered as consecutive characters belonging to the appropriate key.

It is reasonable to provide yet another group of individual symbols comprising parentheses, for example, (,), [,], {, }, <, > and so on. These brackets can also be divided into two subordinate groups, the closing bracket group and the opening bracket group.

With the three symbol groups and their subordinate groups, characters belonging to the subordinate groups are selectively included in the three symbol groups or not included therein. Note that those characters included in subordinate groups have lower priority.

The symbol grouping described above applies to Figure 1-1, where the symbols of each group are seen as successive symbols of the specific keys below. For example, zero-dimensional symbols are regarded as successive symbols of key [0], one-dimensional symbols are regarded as successive symbols of key [1], and two-dimensional symbols are regarded as successive symbols of key [2]. In the grouping of two-dimensional symbols, the symbols in the form of simple closed curves are regarded as the successive characters of the key [8], the symbols in the form of graphics are regarded as the successive characters of the key [7], and the mathematical symbols are regarded as the successive characters of the key [6]. Successive symbols, direction symbols are regarded as successive characters of the key [3], and bracket symbols are regarded as successive characters of any self and remaining keys. The method of associating a symbol group with each key is not limited to the above-mentioned examples, and it can be selectively set by the user.

After taking into account all the above-mentioned factors, the core of this embodiment is that the symbols are divided into three groups (i.e., zero-dimensional, one-dimensional and two-dimensional symbol groupings) or subdivided into ten or less lower-level groups, and are regarded as belonging to a specific key consecutive characters, so the present invention provides a method for entering almost any symbol. Moreover, individual character groups are regarded as consecutive characters belonging to a specific key, which are related to symbol groupings in name, dimension, shape, etc., so that the "Hidden Sequence Control Processing Method (HSCPM)" can be used for objects with a simple layout of characters. on the keypad without any markings.

In this application, the control key of the symbol is [*] or any one of the up/down/left movement keys, and the successive control keys of the number keys or English letters may be [*]. For example, when the key [#] is used as a sequential control key, additional sequential control keys of numbers or English letters are to be arranged in grid cells available on the key [#]. In this case, as described above, it is possible to skip controls not related to the representative character and select the next available control.

8. Use of mobile keys

8.1 Move keys as control buttons

According to the prior art literature, the control keys can be keys on the 4*3 small keyboard or individual keys. When inputting a language with multiple characters and characters with affixes, the 4*3 small keyboard lacks control keys. The present invention proposes that the left/up/down movement keys, which are not frequently used in character input mode, can be used as control keys as mentioned in prior art documents. That is to say, the left/up/down movement keys are used as control keys in the character input mode, which are separate keys arranged outside the 4*3 keypad.

Figure 8-1 shows the key layout on a typical foldable mobile terminal. The button [1] represented by a dotted line is an Internet connection button, which can be set or not set according to the type of terminal. The left movement key is a space input key, and is especially used as a syllable (letter) confirmation key to eliminate the first ambiguity of Korean. The up/down/left movement keys, especially the up/down movement keys are not often used in character input mode.

8.2 Layout of the mobile keys below the keypad

Up/Down/Left/Right keys are usually located above the number keys. In order to use these movement keys as character input keys in the character input mode, however, it is satisfactory to arrange the movement keys at the lower part of the 4*3 keypad together with [*] and [#] which are mainly used as control keys. As shown in Figure 8-2 and 8-3. For the sake of simplicity, if there is no special limitation, the embodiment of the present invention arranges the movement key at the lower part of the 4*3 small keyboard.

As shown in the figure, 4*3 small keyboards and up/down/left movement keys form a 5*3 small keyboard. This means that a single key can be used as 15 (=3×5) grid cells in the PWSM. Likewise, the up/down/left movement keys do not have to be arranged to form a 5*3 small keyboard as shown in Figure 8-3.

8.3 The layout of the mobile key on the left or right

The up/down/left/right movement keys can be assigned to the left or right side of the 4*3 keypad. In this case, the movement keys and the 4*3 keypad constitute the 4*4 keypad in the PWSM. Figure 8-4 shows the layout of the up/down/left/right movement keys on the right side of the 4*3 keypad.

The advantage is that this layout enlarges the size of the display on the terminal, following the trend of terminals with large-sized liquid crystal displays (LCDs), and this layout incorporates the application number filed by this application: 10-2000-0002081, 10 -Advantages disclosed in Korean Patents 2000-0005671, 10-2000-0067852 and 10-2001-0002137, wherein a side battery is attached to a mobile terminal.

8.4 The movement keys are used as control keys and character input keys

The use of the mobile key will be described below in the form of an example, which is not intended to limit the scope of the embodiments of the present invention.

8.4.1 The movement key is used as a symbol control key

For Korean, aspirated consonant control and tight consonant control are assigned to keys [*] and [#] respectively; or aspirated consonant control and consonant-only control are assigned to key [*], since basic vowel control and extended vowel control are assigned to key [#]; or only the extended vowel control is assigned to key [#]. In these cases, if the control is applied using the symbol control assigned to the key [*] or [#] after entering the representative character, when the control key is pressed repeatedly, the order of aspirated consonants, tense consonants and symbols is applied. Given input, the same applies to other languages.

If a symbol control is individually assigned to any one of the up/down/left movement keys, the symbol is input using a combination of a key associated with the corresponding symbol group and a symbol control key for designating the symbol control. Figures 8-5 illustrate the use of the movement key as a control key for selecting symbolic controls. If the control is applied to the zero-dimensional symbol group after inputting representative characters, the input is given like this: point=[3]+[∨], comma=[3]+[∨]+[∨], colon=[ 3]+[∨]+[∨]+[∨], semicolon=[3]+[∨]+[∨]+[∨]+[∨], and so on.

8.4.2 The mobile key is used as a vowel unit in Korean

和“.”时，元音单元“.”与“

”安排在一起，以便于用户输入“

”。为了克服这个问题，本发明将元音单元分配给上/下/左移动键中的任何一个。如果使用上移动键上的元音“.”将符号控制分配给下移动键，则要使用两个移动键。另一种选择是，上/下/左移动键分别分配给三个朝鲜语元音单元。The advantage of the prior art literature is that when using Korean vowel units

and ".", the vowel unit "." and "

"arranged together for easy user input"

". In order to overcome this problem, the present invention assigns the vowel unit to any one of the up/down/left movement keys. If the symbol control is assigned to the down movement key using the vowel "." on the up movement key, then Use two movement keys. Alternatively, the up/down/left movement keys are assigned to each of the three Korean vowel units.

Similar to the case where symbol controls are assigned to aspirated consonant control keys, with symbol controls assigned in order of proximity to BLE, the Korean vowel unit "." can be arranged in the basic grid of any of the up/down/left movement keys The location of the unit. As shown in Figure 8-6. Since the vowel unit "." is not used alone, there is no ambiguity in selecting the vowel unit and sign control by using RSM. In Figure 8-6, one keystroke of the key [V] selects the vowel unit ".", two keystrokes select symbol control 1, and three keystrokes select symbol control 2.

8.4.3 Move keys are used as Japanese affix control keys

For Japanese, the characters in the Japanese syllabary are mapped to each key, while the second and third successive controls are assigned to the key [*], and according to the assignment method 3 of the prior art document, the fourth and fifth successive controls are assigned to button[#]. In this case, the input control of long tone, voiced tone and semi-voiced tone can be assigned to any one of the up/down/left movement keys, as described in Figure 8-7.

8.4.4 The mobile key is used as an affix control key for inputting Arabic vowels

For Arabic, control of affixed vowels can be assigned to any of the up/down/left movement keys.

8.4.5 The movement key is used as the control key in Thai language

For Thai, the sequential control of consonants and vowels share one control button as sequential control buttons. Any of the up/down/left movement keys are used as control keys for other purposes.

8.4 The movement key is used as a shortcut/full conversion control key to use

In the simultaneous input method (CIM), a third ambiguity arises between simple codes and full codes. To remove the third ambiguity, use the "shortcut/full" conversion control in word units. For example, to enter a word through the SIM during CIM when FIM is the basic character entry mode, the user selects the "quick/full" switch control and enters a space (or right movement key), followed by a simple code. Of course, the order of the spaces and "shortcut/full" transition controls is variable. The "shortcut/full" switching control in word units is assigned to any one of the up/down/left movement keys. Controls for both "shortcut/full" switching controls and space entry (using the right movement key) are arranged at the position of the basic grid unit of any of the up/down/left movement keys. As shown in Figure 8-8.

Assume that the English letters in Figure 1-1 are assigned to the number keys in Figure 8-8. If the complete correlation code "4357" of the target word "help" is input in the complete input mode which is the basic character input mode, the input is given like this: "~complete correlation code input+[∨]+[4]+[3] +[5]+[7]+[>]+full code input~". That is to say, "the shortcut/full conversion function and the space input function are combined together, and the movement-related function of the upper movement key [∧] is suppressed at the same time. Therefore, once the key [∧] is selected, the system will be "[4]+. .." is considered to be a simple code rather than a complete code, and the reference index recommends to the user the best word corresponding to the input [4]. After inputting [4]+[3]+[5]+[7], select a space Pressing the key (i.e., [>]) to end the word and end the "quick/full" mode transition causes the system to wait for another full code to be entered. After entering the simple code "4357", selecting the key [∧] causes the system to recognize the end of the word , determines the word "help" corresponding to the simple code "4357", and waits for another simple code to be entered.

When using the right movement key (ie the space key) in the CIM, a third ambiguity between simple and full codes can arise as described in the prior art literature. In this case, to avoid the third ambiguity, as a response to each key input, the system checks whether there is a simple code in the index or a complete code formed according to a predetermined FIM. Using keystrokes combined with word-based "shortcut/full" mode switching and space entry allows the system to determine in advance whether the entered value is a simple code or a full code. This reduces the number of calculations and search steps, so as to improve the performance of the system.

8.6 The movement key is used as the plus/minus/weighing/dividing key in the calculation mode

Regardless of their positions, the four movement keys are used for addition (+), subtraction (-), multiplication (×), and division (/), which are often used in calculation mode. If there is no special limitation, keys for addition, subtraction, multiplication, and division can be marked on the keys, because the calculation mode is not used as frequently as the character input mode. In character input mode, individual keys are used as movement keys or control keys.

In addition, operators used by calculation functions are assigned to addition, subtraction, multiplication, and division, and are selected by the (hidden) repeat selection method. This takes advantage of the fact that frequently used operators in computational patterns (the binomial operator) are rarely repeated. For example, 2++1 does not exist. 24 can be tapped into 2××4 so that the “square” operator is selected using two keystrokes of the multiply (×) key. That is, the multiplication button (×) is selected twice, as if the square operator existed as a subsequent operator. Likewise, to decompose  into "3//2", use two keystrokes of the division key (/) to select the "square root" operation. Since the other binomial operators are rarely repeated, they are seen as appended to the correct add, subtract, multiply, and divide successor operators for selection by the RSM.

Addition, subtraction and division keys are assigned to three of the up/down/right/left movement keys, and multiplication is assigned to the key [*].

9. Activation of the help function

For more convenient use, functions that are not marked with up/down/right/left movement keys in respective input modes may be displayed on the screen (ie, LCD). This function uses a part of the LCD, it is not useful for those who are familiar with this function, but it is helpful for those who do not have the knowledge of the function of each key. For this, refer to Figure 8-1. Figure 9-1 shows another layout of the keypad, where the up/down/right/left movement keys are assigned to the right side of the 4*3 keypad as shown in Figure 8-4.

For brevity, the function of displaying the keys according to the user's preference (ie, the operator assigned to the keys or the symbol group associated with each key) is referred to as "activation of the help function". Activation of the help function may be required for individual modes (e.g., character input mode, calculation mode, etc.) or for each mode (e.g., in character input mode, the use purpose of the number keys or control keys associated with symbol groups) function to complete.

Similarly, due to user requirements, for ease of use, the functions of control keys or number keys related to symbol groups as provided in prior art documents can also be displayed. Regarding this, refer to FIG. 9-2 , which shows a display example, wherein according to the above-mentioned symbol grouping, the number keys associated with each symbol group are simplified into icons on the LCD. For the sake of simplicity, only the symbol selected for the first time from the group of symbols associated with each numeric key is marked on the numeric key in the form of an icon.

10. Use of delete key

”，则使用删除键可以取消最后的输入[*]，并将“ ”恢复为“ ”。这在重复按下控制按键输入相继字符时非常有效。删除键的连续击键可以删除前面通过已知的方法输入的字符。例如，取消键的一次击键可以将输入“ ”恢复为“ ”。其使用取消键的另一次击键就变为“

”，而使用取消键的又一次击键就变为“

”。对于罗马字母，在输入“aba..”(其中“a..”是包括“..”和“a”的带词缀字符)的基础上应用取消键的一次击键就得到“aba”，使用删除键的另一次击键就变为“ab”，而使用删除键的再一次击键就变为“a”。这就是说，前面形成的单词以字符为单位来删除。The use of the delete key may be associated with "cancel of last input" as disclosed in prior art documents. For example, when a user wants to enter " "But using [1]+[*] (figure??) and mistyped"

", use the delete key to cancel the last input [*], and " "revert to" ". This is very effective when pressing the control key repeatedly to enter successive characters. Successive keystrokes of the delete key can delete characters previously entered by known methods. For example, one keystroke of the cancel key can replace the input " "revert to" ". Its another keystroke using the Cancel key becomes "

, and another keystroke using the cancel key becomes "

". For the Roman alphabet, "aba" is obtained by applying a keystroke of the cancel key on the basis of input "aba.." (wherein "a.." is an affixed character including ".." and "a") , another keystroke using the delete key becomes "ab", and another keystroke using the delete key becomes "a".
