Description

Method and apparatus for inputting mathematical operators on a keypad.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an alphabet input device and a method thereof in a keypad, and more particularly, to an alphabet input device and a method thereof in a keypad having a small number of keys such as a telephone key board.

With the development of mobile communication, a function of transmitting and receiving digital information such as characters has been added to a mobile terminal for voice call. Therefore, in the beginning, the keypad provided in the portable terminal for inputting the telephone number also includes means for inputting characters. However, since the size of the keypad used as the input means of the portable terminal becomes smaller, the number of buttons included in the keypad becomes limited. On the other hand, the alphabet of each language greatly exceeds the number of 12 keys included in the keypad. Accordingly, in order to input one alphabet by using the telephone keypad, one or more of the buttons on the keypad must be combined to express the alphabet.

DETAILED DESCRIPTION OF THE INVENTION [

The invention described in the earlier filed application (Application Nos. 10-2000-0031879 and PCT / KR00 / 00601) is summarized as follows.

First, according to the "whole part selection method ", a predetermined number of gratings corresponding to the arrangement of all the buttons in the keypad are arranged in various buttons on the keypad, as shown in Fig. 1, The first button on which the alphabet to be input (abbreviated as "target alphabet" hereinafter) is arranged and the second button on the keypad in combination with the arrangement position of the alphabet in the grids of the first button are pressed to input a desired alphabet do. For example, in Fig. 1-1 of Fig. 1, "A" = [2] + [1] is input.

Using a part of the grating including the reference grating in which the first button and the second button are the same among the gratings of the button, using a part of the grating, and the convenience of the combination of the first button and the second button is high The first use of the ordering grid was the key to the overall selection method. The core of this partial selection method is the reference grid, and the keypad that can take advantage of the reference grid is called the "reference keypad".

Next, the criterion repetition selection method is a method in which the number of times the button is pressed in the order from the alphabet of the reference grid position to the reference grid in the reference keypad configured to apply the partial selection method So that the alphabet is selected according to the method. The criterion repetition selection method is to apply the repetition selection method on the reference keypad. It is called the "simple keypad" for the reference selection method of the reference keypad, and the repetition selection method is applied on the simple keypad I named it a simple iterative selection method.

And there was "control processing method", "subscript control processing method" and "subsequent control processing method". The subscript control processing method is a method of inputting a transformation alphabet by combining a subscript control and a basic alphabet when inputting a transformation alphabet composed of a subscript and a basic alphabet. The following control processing method sets the alphabet of one group assigned to a button to the relationship between the representative alphabet and the succeeding alphabet, and when the subsequent alphabet is input, the subsequent alphabet can be entered by combining the representative alphabet and the subsidiary rank attached to the representative alphabet . For example, in Fig. 4-1, "b = a + [*]"

Subscript control processing and subsequent alphabet control processing are essentially similar, with subsequent control processing being more general. In the case of the subscript control processing, it can be seen that the modified alphabet is attached to the basic alphabet in a certain order in a specific alphabet group. In the case of unicell control processing, since the transformed alphabet can be decomposed into subscripts and basic alphabets, the alphabet group has a strong association in its shape, and the subsequent control has a strong association in its order or pronunciation to be.

The advantage of applying the control processing method is that the arrangement of the keypad can be simplified by not displaying the subsequent alphabet (or modified alphabet) on the keypad through association between the basic alphabet and the subsequent alphabet (or modified alphabet) It was possible to enter the alphabet without ambiguity through control processing. The simplified keypad by omitting the succeeding alphabet was called a "subsequent keypad" and the simplified keypad by omitting the modified alphabet was called a "simplified keypad" and a combination of both was called a "simplified keypad". The keypad showing all subsequent alphabets (or modified alphabets) was referred to as the "entire display keypad" in contrast to the simplified keypad.

The user can input the subsequent alphabet (or modified alphabet) through the control processing method in the entire display keypad, and conversely, the user who memorizes the arrangement of the entire display keypad in the simplified keypad can use the input method in the entire display keypad . This simplified keypad can be extended to configure the entire display keypad, and compatibility with the entire display keypad allows the user to input the subsequent alphabet through the control process according to the user's convenience.

One of the effects of applying the control processing method is that, besides the effect of eliminating the ambiguity, by "hiding" the subsequent alphabet on the keypad through the association between the representative alphabet and the succeeding alphabet, The keypad can be simplified. This is called "concealed control processing method" for convenience. However, as mentioned in the earlier application, the subsequent alphabet can also be input through the control processing method in the entire display keypad in which the subsequent alphabet (or modified alphabet) is displayed on the keypad. This is called "non-concealed control processing method" for convenience.

The present invention presents improvements on the extension of the applicant's earlier application (Application Nos. 10-2000-0031879 and PCT / KR00 / 00601). Also, we propose a method for inputting common phrases by using short input method and input parallel input method by using short input method and full input method to input all the desired alphabet, We propose a method to improve the convenience of input. In this paper, we propose a method for inputting various symbols on a keypad. Also, we propose a method to utilize a movement button which is not frequently used in the alphabet input mode among the movement buttons as a control button.

&Quot; Specific contents for carrying out the invention ".

Through the present invention, it is possible to efficiently input the alphabet in the keypad. Various symbols can be input by the concealed type control processing method, so that a compact keypad can be maintained.

In addition, a simple code can be generated by using the correspondence relationship between alphabets and numbers arranged on a keypad, and a simple input method can be realized through the simple code. In addition, when a parallel input method is applied, Can be input.

If the relay server that interprets the simple code is used, the user inputs the simple code even if the third server side requires a phrase other than the simple code, and stores the corresponding phrase corresponding to the simple code and the simple code on the third server side The relay server can interpret the simple code inputted from the user by the relay server and deliver the phrase corresponding to the simple code to the third server side.

First, the contents of the earlier application for each language are supplemented as follows. It is obvious that the content of one language that can be applied to another language can be applied to other languages even if it is not mentioned in another language.

[Example]

1. Common Supplement

1.1 Application area of the keypad in the prior art and the present invention

It is apparent that the prior art and the keypad according to the present invention can be applied to all fields such as a numeric keypad of a mobile terminal or a standard keypad, or a keypad or a door lock which is configured by software on a screen. Also, it is obvious that the numeric keypad provided on the standard keyboard differs from the prior art and the arrangement of the keypad and the numeric buttons according to the present invention. However, it is obvious that the prior art and the arrangement of the keypad buttons in the present invention can be applied to the keypad provided in the keyboard. For example, in the prior art and in the present invention, the alphabet placed on the [1] button is arranged on the [1] button of the numeric keypad provided on the keyboard, and arranged in the same manner as described below to utilize the alphabet input, simple code, Can be used for.

1.2 Setting of the batting delay time and the releasing delay time

In a language in which consonants and vowels appear alternately such as Korean and Hindi, a pair of a representative consonant and a representative vowel is assigned to each button, and a consonant is selected by selecting one vowel as two vowels, For example, if an algorithm is implemented to recognize two identical input buttons within a time interval of 0.1 second as a vowel, it is possible to efficiently implement the algorithm while reducing the sense of rejection to the user. This delay time should be determined in consideration of the time interval that is universally pressed for a certain time when the same button is continuously pressed. This delay time is referred to as "swing delay time" for convenience. In addition, it is possible to realize two consonant sounds of the same button inputted at intervals of a predetermined delay time (for example, 1 second) or more to be recognized as two consonants. This delay time is referred to as "release delay time" for convenience. This can also be applied when the same button is pressed more than three times.

For example, in FIG. 4-1 or FIG. 4-2, if [1] + [1] is input with a delay time of 0.08 seconds, it is primarily recognized as a vowel "ㅗ" ("A", "a") when it is input. If the input is made with a time delay of 0.5 seconds, it is possible to determine whether one vowel or two consonants are input through the appearance structure of consonants and vowels in the language. In addition, even when the delay time is 0.08 seconds or 1.1 seconds, it is possible to finally determine whether one vowel is input or two consonants are input through the appearance structure of consonants and vowels in the language.

In the past, if only one button is set at a predetermined time interval (for example, one second) and the same button is continuously input within the corresponding time, two consecutive strokes are recognized. The difference is the difference between the reference time delay value (eg 0.1 second), which is judged to be 2 consecutive times, and the time delay value (eg 1 second), which is judged by each other.

In general, it can be said that the iterative selection method is superior in terms of the convenience of input among the partial selection method and the iterative selection method. This means that ambiguity can be largely avoided by using the structure of a specific language in which consonants and vowels appear alternately while utilizing the advantages of the iterative selection method (simplicity and convenience of input rules) The delay time can be set to be different from each other, and the user can specify the delay time, thereby simplifying the implementation of the algorithm.

1.3 How to handle chain control

The subscript control processing method in the prior art is essentially the same as the subsequent control processing method, and the subsequent control processing method is a more general method. In other words, in the Korean example of the earlier application, the relationship between a, b, and 설명 is described as a relation between the representative alphabet and the modified alphabet, and is described as b = a + , ㅋ (2nd), ㄲ (3rd) and so on.

In the case of Japanese of FIG. 2-1, an input example by a subsequent control processing method is shown again as follows. Select the relationship of the following alphabet with the following alphabet as [1], [2], [3], [4] ], And 2nd, 3rd, 4th, and 5th controls are placed on a random control button (eg, [*]), and repeatedly selected according to the number of times the button is pressed to input a subsequent alphabet by a combination of a representative alphabet and a subsequent alphabet . For the sake of simplicity, it is assumed that the control is selected in brackets. For example, when the input is applied after control, a = [1], a = a + {2nd} = [1] + [ = {1} + [5] = [1] + [4]} [1] + [*] + [*] *] + [*] + [*] + [*].

Here, the relationship between the representative alphabet and the subsequent alphabet such as (the alphabet), (2nd), (3rd), (4th) and (5th) (Eg, [*]) to be selected by pressing one of the control buttons (eg [*]), and the second letter of the next alphabet The next alphabet (second subsequent alphabet) is input to the third subsequent alphabet, and the new alphabet is added to the third subsequent alphabet. It is possible to input a combination of the second letter and the "next control" by considering it as the representative alphabet (second representative alphabet). That is, u = i + {next} = [1] + [*] + [*]. In the same way, when you enter the fourth alphabet, the preceding alphabet (the third alphabet) is regarded as the new alphabet for the fourth alphabet (the third alphabet) [1] + [*] + [*] + [*]. The same is true for the fifth consecutive alphabet.

This result is the same as inputting the combination of the representative alphabet and the accessory rank control while placing the accessory rank control (2nd, 3rd, 4th, 5th, ...) on the control button and selecting it by the repetition selection method . If we can select the primary representative alphabet A without ambiguity, it is easy to see that it can be input without ambiguity in the second-subsequent alphabet, and so on with the rest of the subsequent alphabet. In other words, it is possible to input it without ambiguity, and it is combined with "the next control", so that the result is not ambiguous and the subsequent alphabet You can enter an index.

In this association of the representative alphabet with the succeeding alphabet, it is assumed that the control button does not have an accessory rank control, and that there is only one "next" control, and when the subsequent alphabet is input, the preceding alphabet is regarded as the new representative alphabet, The method of inputting the control in combination is called "chain type follow-up control processing method" for convenience. Although the user does not need to display the subordinate rank control on the preceding control button in the prior art, the user has to recognize that the specific button is a subsequent control button. The advantage of this chain type subordinate control handling method is that the "next control" The display can be simplified even if it is displayed. In the present invention, the results of "subsequent control processing method" and "chain type follow-up control processing method" described in the prior application are the same and are used in combination.

1.4 How to Handle Skip Controls

을 입력함에 있어서 이를 .. 과 e 를 각각 조합하여 입력할 수 있음을 보였다. 혹은 e 를 기본알파벳으로 두고 이와 모양 혹은 순위 등에서 연관성을 가지고 있는 나머지 부속된 알파벳을 후속알파벳으로 두어, 부속순위와 기본알파벳의 조합으로 입력할 수도 있었다(예를 들어 e(기본알파벳),

또한 이렇게 알파벳(즉 특정 숫자버튼)과 조합하여야만 의미를 가질 수 있는 컨트롤들이 배치되는 컨트롤 버튼은 반복적으로 사용하여도 모호성 없이 변형알파벳 혹은 후속알파벳을 입력할 수 있었다.In the subscript control processing method, the transformation alphabet consisting of ".. + e"

, It is shown that it is possible to input the combination of .. and e respectively. Alternatively, e can be entered as a basic alphabet, and the associated additional alphabet, which has relevance in shape or ranking, can be placed in a subsequent alphabet, for example, as a combination of an accessory rank and a basic alphabet (for example,

In addition, the control buttons, which are arranged in such a way that they can be combined with alphabets (that is, specific number buttons), are able to input a modified alphabet or a subsequent alphabet without ambiguity even by repeated use.

의 변형알파벳이 사용되며, 변형알파벳에 사용된 윗점의 종류는 5가지(/,^,｀,..,s) 이다. 첨자컨트롤의 선택순서를 /,^,｀,..,s 로 하였을 경우, ^a=a+[*]+[*] 로 입력하여야 한다. 그러나, 프랑스어에서 알파벳 a 에는 첨자 "｀"와 "^"의 두가지 밖에 결합할 수 없으므로, 첨자"/" 가 붙을 수 없고, 이를 건너뛰어 결합이 가능한 첨자"^"이 선택되도록 하면, ^a=a+[*] 로 입력할 수 있다. 이를 편의상 "건너뛰기 컨트롤처리방법"이라 부른다. 즉 이는 a(기본알파멧),｀a(2nd),＾a(3rd) 와 같이 후속알파벳의 부속순위를 두고 컨트롤처리방법으로 후속알파벳(혹은 변형알파벳)을 입력하는 것과 같다.For Roman, 11 in French

, And the five types of upper points used in the transformation alphabet are (/,,,,,,,,,). If the selection order of the subscript control is / /^,`,..,s, you must enter ^ a = a + [*] + [*]. However, in French, the alphabet "a" can not be combined with the suffixes "" and "^", so if the suffix "/" can not be attached and the suffix "^" a + [*]. This is called "skip control processing method" for convenience. This is equivalent to typing the subsequent alphabet (or modified alphabet) in a control processing method with the following alphabetical order of precedence, such as a (basic alphabet), `a (2nd), ^ a (3rd)

Likewise, in Japanese, a line in which a long sound exists is only the alphabet of the line or line and the line of the line, and the line in which the whisper is present is only the alphabet of the line, line, line, It exists only in the alphabet of the line. In the end, there are two variants of the alphabet, the long and the whitish, and there are two variants of the alphabet, the whisper and the counterpoise. Therefore, it is possible to enable the subscript control button by pressing the subscript control button once when inputting the modified alphabet of the remaining alphabet except for the six alphabets in which two modified alphabets exist. For example, you can use the control button with the [*] button, and then apply the input after the control, such as a = a + [*], a = or + [*]. In the case of six alphabets with two variants, the control can be selected in order of frequency of use of the variant alphabet. For example, you can use the control button as the [*] button, and when you apply the control after inputting the controls, you can use the +, +, + *], Po = + [*] + [*]. That is, in control selection, a control that can not be combined with a basic alphabet does not produce its effect. For example, if you use [=] or [*], you can treat [*] as not selecting the long sound control but selecting the long sound control because the basic alphabet combined with the control has no long sound, This is because they choose skip control.

The advantage of strictly choosing a control is that it allows input of unused alphabets. For example, there is no alphabet with the suffix ".." in the French alphabet b, but it is possible to input these alphabets, and there is no alphabet with a dot on the Japanese alphabet, You can do it.

Even if the control is selected as an iterative selection method, it is possible to input the representative alphabet displayed on the keyboard without ambiguity at the time of inputting through the control processing (for example, if there is only one representative alphabet displayed on the keyboard, , The remaining subsequent alphabets can be input without ambiguity). This is because the ambiguity is removed through control processing, because the control can not represent a specific alphabet by itself, but must be combined with another alphabet.

1.5 Input by control processing method of numbers and English alphabet

It was explained in the previous application that the native language alphabet can be arranged in the order of "close to the reference grid", and then the numbers and the English alphabet can be arranged. In applying the standard iteration selection method, Alphabet, and number can be selected. Likewise, in applying the subsequent control processing method, not only the native language alphabet belonging to a specific button, but also a number and an English alphabet (in the case of non-Roman alphabet) can be input through a subsequent control processing method.

Numbers or English alphabets may be followed by the following alphabetic characters following the native language. For the sake of convenience, for example, the case of Japanese is a (alphabetic), (2nd), (3rd), 4th, 5th, 1 (6th), 7th, q (8th) z (9th). Also, if you have available buttons to control numbers or English alphabets, you can use the control buttons for the alphabet, 2nd, 3rd, 4th, (3rd alphabet), 1 (2nd),. (3rd), or q (), for example, by placing the other buttons 4th), and z (5th). For example, 1 = a + [#] = [1] + [#],. = A + + [#] + [#] = [1] + [#] + [#] + [#]. If the control buttons are available, you can also use the control buttons for numeric input and the control buttons for the English alphabet.

This can be applied to other languages and can be applied to input of various symbols described later.

1.6 Grouping according to pronunciation of the English alphabet

In constructing the keypad of each language in the prior art, alphabets are grouped into similar pronunciation groups in consideration of application of the control processing method and use for memorization, and assigned to each number button. In the case of English, a method of grouping three or four alphabets according to the current dictionary order and assigning each group to each number button is widely used, but it is also possible to group them by assigning them to each number button in consideration of similarity of pronunciation. Here are some examples of grouping consonants in English into nine groups according to pronunciation similarity.

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

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

The following is an example of grouping English consonants into 8 groups.

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

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

In addition to the above examples, many variations are possible. Five vowels can be grouped into groups of two. This can be convenient when applying a simple input method using a simple code described later. In the case of the non-English language language, in assigning the grouped English alphabets to each button, the similarity with the native pronunciation group can be considered. For example, in the case of Korean, G, K, and Q groups are assigned to a button assigned a letter "a" similar in pronunciation. In Japanese, G, K, and Q groups are assigned to the buttons assigned with the letters "or" similar in pronunciation. Therefore, in the grouping of the English alphabet, grouping can be performed considering the native language alphabet grouping of each language.

2. Supplementary information for each language

Hereinafter, the contents of the prior application for each language are described and the following developments are described. It is obvious that the contents described in the supplement of each language can be applied to other languages even if the contents described in one language can be applied to other languages without specifically pointing them.

2.1 English

As in the case of English, alphabets other than the representative alphabet can be displayed on the keyboard and input through the control process, just as the first alphabet can be input through the control processing method on the entire display keypad in the prior art. In English, the subsequent controls (2nd, 3rd) can be placed on the same control button (for example, the [#] button) or placed separately on different buttons (for example, #] button). In the case of English, when ABC is arranged in one button, when A is a representative alphabet, B and C are input through subsequent control processing respectively, and when B is a representative alphabet, A and C are respectively subjected to subsequent control processing . As mentioned in the earlier application, the order of the representative alphabet and the subsequent alphabet may be determined in consideration of the frequency of use and the like.

For example, in the group A, B, and C, when A is a representative alphabet and the 2nd and 3rd controls are placed on the [*] button and the input is applied after the control, B = A + {2nd} = [2] , C = A + {3rd} = [2] + [*] + [*]. A = B + {2nd} = [2] + [*], C = 1, 2, 3, and 4 are obtained by placing the 2nd and 3rd controls on the [*] B + {3rd} = [2] + [#]. FIG. 1-2 is an example in which the center alphabet of the alphabet of each group is centered on the representative alphabet and the succeeding alphabet is arranged on the left and the right, respectively, in order to facilitate the identification of the alphabet. D = E + {2nd} = [3] + [*].

If four alphabets P, Q, R and S are assigned to the button [7] and four letters W, X, Y and Z are assigned to the button [9], as indicated in the Korean example of the prior application , One alphabet among the four alphabets may be arranged in a grid constituting the upper and lower adjacent combinations, and the partial selection method may be applied. See Figures 1-3.

2.2 Japanese

In the case of Japanese in the first application, alphabetical groups are grouped based on the 50-degree alphabet, and the remaining alphabets (a, b, c, ...) In the preceding paragraph. In applying the subordinate position of the subsequent alphabet presented in the earlier application, it is possible to simply apply the 50-tone diagram as shown in the following table, which is almost similar to Method 3 of the earlier application. This can give the user an affinity with the simplicity of the subsidiary ranking. May be deemed to be attached to any representative alphabet, as in the earlier application. It may also be considered that an empty letter is attached to an empty space in a row or a row with a 50-degree alphabet (eg, a, b, c) attached.

In the case of Japanese, the alphabet of the first stage, which is considered to be the most representative for convenience, is defined as a representative alphabet, which may also be an alphabet of an arbitrary stage or an arbitrary alphabet in each group as a representative alphabet You may. (1), [2], [3], [4], ...) in the row of the button on the keypad as mentioned in the earlier application, , Or the column may be assigned as a reference ([3], [6], [9], [2], [5], ...). Likewise, a row can be arbitrarily assigned without being allocated on the basis of a row or a column.

In the Japanese example of the earlier application, if you put "n" at the default grid position of the [0] button, and you have 2nd, 3rd, 4th and 5th controls on the [*] and [#] In order to utilize it as a control button for inputting long sound / mute sound / welcome sound, I have assumed that "N" is assigned to an arbitrary numeric button other than the [0] button. However, in this case, you can place a "N" in the reference grid position of the [0] button, add a long tone / mute / fade control in the order close to the reference grid, and apply the repeated selection method to the control selection. Because "n" does not appear in succession in one word. See Figure 2-1. This makes it possible to select non-consecutive alphabets on a single button with the corresponding alphabet, and to select other controls on the two letters, three letters, ... for all other languages. This property is also utilized in the method using the vowel element of the following language.

2-3 Arabic

There are 28 consonants in Arabic. Arabic consonants having the meaning of numbers in the prior art are grouped as follows and allocated on the keypad buttons. The alphabet having the smallest numerical value is arranged as the representative alphabet of each group, and the remaining alphabet In a sequence close to the reference grid (described in the earlier section) from an alphabet having a small number of meanings on the keypad. In addition, a method of inputting an alphabet by control processing in Japanese, Roman alphabet, Korean, Indic, Arabic, In the case of Arabic, we have proposed a method of treating subscript control by treating a vowel as a subscript.

In this paper, we propose a method of controlling the consonants of Arabic (subsequent control processing). The following is an example of grouping consonants of Arabic in the earlier application and assigning them to each button.

The alphabet having the meaning of 1, 10, 100 assigned to the [1] button is displayed on the keypad as the representative alphabet having the meaning of 1, and the remaining alphabet having the meaning of 10, 100 can be subsequently controlled. The control button can be any button as in the prior art. If you use the [*] button for subsequent control buttons and the 2 ^nd and 3 ^rd controls, the average input number for consonant input is 2. Since only one alphabet is placed per button, there is no need to select the whole part selection method when selecting the alphabet displayed on the button. Since the arrangement of the alphabet is conceptual, it is not necessary to place the alphabet on the keypad as described below.

You can separate the subsequent controls with other buttons, as in the case of Japanese in the earlier application. For example, if the 3 ^rd control is distributed to the [#] button, the average input number is approximately 1.7 ((1 + 2 + 2) / 3), and 28 consonants can be entered without ambiguity .

In the present application, an alphabet having a small number of meanings is used as a representative alphabet of each group regardless of the use frequency of each unit, and an alphabet having a small number of meanings is selected first . The control can be pre-input or post-input.

. The same is true for the remaining alphabets. In this case, the [#] button can also be used for vowel control processing.

As shown in FIG. Other alphabets with an upper dot may allow this upper-point control processing in parallel with other input methods. In this case, it becomes easy to use the [0] button as a control button for another purpose (for example, a vowel control button).

Can be allowed in parallel. When an alphabet having the meaning of 1000 belongs to one group alphabet,

or

. I.e., [*] in the button that is arranged in 2 ^nd, 3 ^rd, 4 ^th control and can be thought that the 3 ^rd, the 4 ^th control arrangement in the [#] button. In consideration of a fact that the Arab left horizontal writing from the right, that is assigned a 2 ^nd, 3 ^rd, 4 ^th control the [#] button, it is also possible to place the 3 ^rd, 4 ^th control the [*] button .

This means that in Arabic, it is possible to input the consonants mainly used on the average of about 1.7 tatami (without ambiguity), and Arabs know the meaning of the numbers held by the native language alphabet, There is a great advantage in that the alphabet can be input without displaying the unit alphabet (i.e., the representative alphabet). In other words, when applying the method of the present application through the keypad with only numbers, it is possible to determine which alphabet is the unit alphabet, which control button is used for which unit of alphabet, and the subsequent control uses one control button If you know only the rules of selection of each subsequent control and how to input controls, you can input most of the alphabets (Arabic consonants) that you need in real life.

As indicated in the earlier application, vowels can also be controlled. If both [#] and [*] are used for consonant control processing, the alphabet with a meaning of 1000, as in the Japanese original of the earlier application, (0) button as a control button for vowel processing, and the subscript type vowel (vowel control, subscript control) can be selected by repeating selection method. In the same way, the vowel control (subscripted vowel) is selected according to the number of times the button is pressed in order of frequency of use. If only one [*] is used as a consonant follow-up control button, you can use [#] as a vowel control button, or use both [#] and [0].

In the examples of Figs. 3-1 and 3-2, alphabets (1 unit alphabet) having the meaning of 1 to 9 are used as the representative alphabet of each group, but alphabets having the most frequently used in each group may be represented by the representative alphabets . To reduce confusion, the alphabet of any unit of 1 unit alphabet (alphabet with 1-9 meaning), 10 unit alphabet (alphabet with 10 ~ 90 meaning), 100 unit alphabet (alphabet with 100 ~ 900 meaning) It can also be a representative alphabet.

Likewise, alphabets selected by subsequent controls can also be alphabets of each unit according to frequency of use. For example, if the 100-unit alphabet is the most frequently used, and it is used as the representative alphabet, and then the 1-unit alphabet is used frequently, the 2 ^nd control (ie, one unit control in this case) , And to allow input of a 10-unit alphabet by combining a 3 ^rd control (ie, a 10-unit control) and a representative alphabet.

Since it is possible to input the subsequent alphabet through the control processing method in the entire display keypad in the prior art, likewise, the consonant can be inputted by the subsequent control processing method in the keypad of the prior art and the vowel can be inputted by the subscript control processing method Do. 3 * 4 Within the keypad, it is possible to distribute control buttons for consonant input to the [*] and [#] buttons when the subscript control buttons for the vowel are [0].

2.4 Korean

2.4.1 Separating Dumb Sound Controls, Neutral Controls

In the example of the prior art, as shown in FIG. 4-1, the treble control is assigned to the [*] button and placed at the position of the reference grid, and the treble control is placed in a grid close to the next reference grid, To select the punctuation control in two strokes. However, when an extended vowel (two vowels) is input, the time delay is naturally provided between vowels and vowels, so that even if the extended vowels are not inputted through the control processing method, there is practically no ambiguity. Therefore, in this case, as in the Japanese example of the prior application, the punctuation control may be selected on the [#] button 1 by further assigning the punctuation control to the [#] button and placing it at the position of the reference grating. See FIG. 4-2. In this case, when the control line is input, it becomes = = {shudder} + a = [*] + a, ㄲ = {chord} + a = [#] + a.

2.4.2 Controlling the Basic Vowel

In the method of using a pair of consonant and vowel in the applicant's initial application (10-2000-0025183), it is also possible to set the follow-up control button to [#] and [#] You can also enter a basic vowel by entering a number button. " This means that the basic vowel control can be input without any ambiguity by inputting the basic vowel through the control processing method as shown in Fig. 4-3. As noted in the earlier application, the basic vocabulary on the keypad can also be entered by control processing as in the case of Japanese (input by control processing of the subsequent alphabet on the entire display keypad).

In this case, the convenience of the input is less than the repeated selection of the basic vowel by the corresponding button 2, but the ambiguity can be completely eliminated. Since the basic vowel is frequently used, it is a matter of course that the "basic vowel control" for basic vowel input must be selectable by one control button. FIG. 4-3 is a drawing to which the "basic vowel control" for controlling the basic vowels is added in the drawing presented in the prior application. The default vowel control is selected on control button 1, and the extended vowel control is selected on control button 2. In the example of Figure 4-3, after applying the post-control input, a = [3] + [#], ㅐ = [3] + [#] + [#], ㅓ = [4] + [#] + [#]. The same applies to the remaining vowels and extended vowels, and can be applied to the similar vowels vow = [1] + [#], v = [1] + [#] + [#].

Since the association between the representative consonant and the basic vowel is insufficient, it can be seen that the basic vowel is displayed on the keypad and the basic vowel is input by the non-consonant control processing method.

2.4.3 Sharing Whistle Controls and Expanded Bar Controls

As in the Thai example of the earlier application, one subsequent control button can be used in common for subsequent consonants or subsequent vowels. For example, you place the Shock control and the Expanded Vowel control on the same grid of the same control button. As described in the earlier application, when the control buttons for subsequent consonant processing and the control buttons for subsequent vowel processing are separated, the line input or post input of each control can be applied differently.

2.4.4 Program Implementation

Figures 4-4 are merely an example of a flow chart for implementation and more efficient programming is possible. For example, in Figure 4-4, a slightly more efficient implementation is possible by checking for consonants that can be made double-spaced if the consonant portion of the backing comes in.

An example of Korean presented in the prior application can be applied to other languages having similar characteristics (a structure in which consonants and vowels appear alternately). For other languages, it is necessary to reflect the characteristics of the emergence of other languages.

In the Korean example, the first three letters (Input 1, 2, 3) from "Word Start" can always be confirmed as consonants and vowels of the first syllable (letter). Of course, this does not apply in Hindi when the syllable of "moja" comes first. Next, input 4 should be the first syllable (character) or the beginning of the second syllable (character). Although all efficient detailed procedures can not be shown due to the size of the flow chart presented in the previous application, if input 4 is judged to be the same as previous input (input 3), input 4 and 5 can not be a double vowel Can be determined in advance. Because inputs 2 and 3 are defined as vowels, inputs 4 and 5 must not be the same vowel to form a double vowel with vowels. If input 4 is not the same as the previous input, compare with the next input (input 5) as shown in the flow chart and proceed to the next procedure.

If input 5 is the same as the previous input, check that the double vowel can be achieved as in the flow chart and proceed to the next step. The following is an example of a case where a double vowel is not formed. If input 5 is not the same as the previous input, input 4 can be determined as the basis of the first syllable (character), and input 5 can be the beginning of the double syllable of the first syllable or the second syllable At this stage, if inputs 4 and 5 can be doubled, then input 5 can be prefixed with the second syllable (character) if it can not be doubled. In the case of Korean, only 14 combinations (14 * 14 = 196) are possible, but only 11 combinations of ㄶ, ㅄ, ㄺ, ㄻ, ㅀ, ㄵ, ㄼ, ㄳ, ㄾ, ㄿ, ㄽ are possible. Because. One syllable (letter) has been confirmed, and input 5 is entered again, and then proceed from the beginning. If input 5 is the same as input 4 and inputs 2 and 3 can not be doubly voweled, input 4 can be set to the beginning of the second syllable (letter) as the end of the first syllable (letter). Although not represented in the flow diagram as a floor constraint, it is a matter of course that can be taken into account in programming the invention of the prior application.

In the case where a double vowel can be obtained, the flow can be proceeded as shown in the flowchart. And in all other cases where ambiguity occurs, the words (or syllables) in which the ambiguity occurs (as shown in the input examples and flowcharts of the prior application) are terminated in one end, If the end of the word is terminated, the input x is replaced with the last syllable (character). If the end of the word is terminated, It can be confirmed as a contour (ie, in the example, "+ input x").

2.4.5 Basic consonant combination processing of hyphenation

For all Korean keypads mentioned in the applicant's earlier application, it is possible to process a hyphen (consonant) with a combination of basic consonants, but for convenience, we will refer to FIG. 4-1 as a reference.

Also, when inputting a pair of consonants (a pair of consonants) in combination of two notes, it is possible to proceed similar to the case where the input 4 and the input 5 are not the same. However, if the first syllable ends with vowels and the beginning of the second syllable is transitive, ambiguity can occur as in "ot cu <=> ottogi" The "" "of" put "can not be entered in Jongseong or KIPO editor, so it is noted as such for convenience). In addition, even if the first syllable ends with a base, if the first syllable of the second syllable is infrequent, and the base of the first syllable and the beginning of the second syllable are the same (for example, The second consonant of the second syllable (eg c + c) "is recognized as a vowel and can be a double vowel (in the example" ㅗ + ㄷ "=" ㅗ + [3] + [3] If possible). Therefore, due to the characteristics of the invention of the prior application, the ambiguity can not be removed by controlling the trueness by inputting the trueness, so that more ambiguity may occur than when the trueness is controlled.

In the case of the "Otogi <=> Ottogi", the user can avoid this by using a time delay or segment input (input means by which the right syllable is confirmed). The same is true of the "っ て っ き <=> and putting". In the latter case, however, there are eight cases of ㅔ, ㅢ, ㅘ, ㅚ, ㅝ, ㅟ, ㅖ, ㅒ in the case of a double vowel in Korean (except two combinations of three basic vowels) It ends in ㅣ, a, or.. Therefore, if three consonants among the five consonants, ν, ƒ, ƒ, ƒ, ƒ, and ƒ without consonants exist and the three vowels,,, and ㅓ are arranged in pairs, , It can not always be "and" even when inputting two consonants into the basic consonant, so it can always be correctly recognized as "oops".

In this case, it is possible to be recognized as a "grasshopper" without having to change the existing algorithm by only the above grouping (since the existing algorithm checks if it can achieve a double vowel). This has the property that when the first syllable (character) has a pedestal and the next syllable (character) starts with a hyphen, it can not be recognized as a vowel even if two consecutive same buttons are input to input a hyphen.

For example, in the case where a hyphenated word is the first syllable at the beginning of a word (input 1 and 2 are initialized by hyphenation, inputs 3 and 4 are determined as a vowel), a slight modification to the flowchart of the prior art is required, It is easy for a person skilled in the art to understand the idea of. If inputs 1, 2, 3, and 4 are all the same button, input 1 is initialized to a normal tone, input 2 (input 2) is input, , There may be ambiguity with the vowel and input 4 being vague (i. E., "Person + moderator"). As in the prior art flow chart, this receives the next input ("input x" for convenience) It is impossible to achieve double support by checking whether the consonant and double suffix of the "+ moja" can be achieved and whether the word suffix can be achieved. In some cases, ambiguity is overcome by processing the input x as the " There are cases where it can be done. The same concept can be applied to the case where a double support can be obtained by checking whether the word is terminated by receiving the next input.

By treating the verse as a combination of the two equal parts, ambiguity can be seen as ambiguity caused by the application of the iterative selection method, even when ambiguity occurs, and the "index" provided for overcoming the ambiguity described below It can be overcome.

As a result, there is a slight ambiguity by applying the iterative selection method. By processing the two consonants with a combination of two basic consonants, it is possible to increase the convenience of input and improve the simplicity of the input method even if there is a slight increase in ambiguity .

The distinction of a word can be made by any means that can distinguish between words and words such as space, mode change, move button, confirmation, end of input.

2.5 Hindi

By assigning the Hindi consonants to 9 groups and assigning them to the [1] - [9] buttons in the applicant's initial application, the vowel assigned to the [0] button is selected with the [0] button 1. For consistency, Group, and the representative consonants are always selected as one and ten vowels as two. A collection __ (ri) that is not placed on the keypad and is not frequently used can be handled by the control processing method. In grouping the consonants into 10 groups, it is possible to group them by taking into account the similarity of pronunciation as presented in the prior application. An example of grouping into 10 groups is as follows.

(a) 는 자음과 자음 사이에서 생략될 수 있다고 한다. 즉 자음이 연속하여 나오게 되는 것이다. 이러한 경우 "자음 + __(a) + 자음" 으로 입력하더라도 "자음 + 자음" 으로 표시되도록 하는 것은 매우 용이한 일이다. 물론 직접 "자음 + 자음"을 입력하는 것도 가능하나 이 경우 동일한 대표자음이 연속하여 선택되어 두개의 자음이 하나의 모음으로 인식될 수 있는 가능성이 많아진다. 따라서 양자(모음 __(a)를 자동 생략 혹은 사용자가 생략 입력)를 모두 허용할 수 있다.And the first collection of Hindi

(a) can be omitted between consonants and consonants. In other words, consonants come out continuously. In this case, it is very easy to display "consonant + consonant" even if "consonant + __ (a) + consonant" is input. Of course, it is possible to directly input the consonant + consonant, but in this case, the possibility that the same consonant is consecutively selected and two consonants can be recognized as one vowel is increased. Therefore, it can accept both quantum (auto-skip collection __ (a) or skip input by user).

2.6 Myanmarese

There are 33 consonants in Myanmar. The following is an example of grouping into 9 groups as in Hindi example. Grouping into 10 groups can be done by similar techniques.

3. Minimization of ambiguity through mathematical modeling in the method of using pairs of primitives

In a language in which consonants and vowels are repeatedly appearing in Korean, Hindi, Myanmar, etc., a basic consonant and a basic vowel are arranged in pairs on a keypad number button, Can be input efficiently.

And, in Korean, it is suggested that input, control, and basic vowel can be controlled by inputting vowel, tremor, and extended vowel. Hindi, etc., it is suggested that the remaining consonants attached to the representative consonant can be input for subsequent control processing. Here, we present a method that can reduce the ambiguity as much as possible in the invention of the prior application.

When multiple alphabets are assigned to one button on the keypad and the repetition selection method is applied, the ambiguity as described in the earlier application is obtained due to the inherent nature of the repetition selection method. For example, if you enter [2] + [2] + [2] in succession, you will not know if it is AB or BA.

For the sake of simplicity, in Korean, for example, most syllables in Korean are "consonants + vowels" (abbreviated as "vowel + vowel") or "consonant vowel vowel + consonant . This also applies to languages such as Hindi and Myanmar. However, in Korean, one syllable has the characteristic of forming a single letter (cilical letter).

The most frequently occurring form of ambiguity occurs when the first syllable is made up of "mother + mother" and the second syllable consists of "mother + mother", the "mother" of the second syllable is placed on the same button , The first consonant of the second syllable is recognized as the last consonant of the first syllable and the "mojar" of the second syllable is recognized as "mother + mother". To minimize this ambiguity in the end, we can see that "modifiers", which are frequently combined in a syllable of "self + modulo", should not be placed on the same button as possible. In other words, in a syllable composed of "a child + a mother" in a corpus, a vowel and a consonant with a high transition frequency from a vowel (neutral) to a consonant (vowel) should not be placed on the same button. In Korean, the same ambiguity may occur when the first syllable is composed of "child + mother + mother" or when the second syllable is composed of "child + mother + child + child", but not many cases. In other words, in the case of Korean, it is necessary to consider the frequency of the mother-to-child transfer in the case of the second syllable consisting of "mother + mother + mother + son"

From the opposite point of view, if the first syllable is made up of "self + modulo" and the second syllable is made of "self + moh", if the "syllable" of the second syllable is placed on the same button, The syllable is recognized as "self + mod" and the "syllable" of the second syllable is recognized as "modulo" and combined with the consonant of the preceding syllable to be recognized as "self + modulo". To minimize this ambiguity, it is important to ensure that "self + moons", which are often combined in a syllable composed of "self +", are not placed on the same button as possible. In the case of Korean, the first syllable is also composed of "child + mother + child + child", but not many cases.

Although the above cases and other cases where ambiguity occurs have been proposed by the prior application, it is not so many cases, and therefore, a method of minimizing ambiguity is considered by considering only these two cases. This is applicable not only to Korean but also to languages in which consonants and vowels appear in succession, such as Hindi, Myanmar, etc., and it is more applicable to the remaining languages in which the rules for repeated occurrence of consonants and vowels are simpler than Korean.

Referring again to Fig. 4-1, a flowchart for identifying an alphabet in the case of selecting a basic consonant and a basic vowel arranged on a keypad in Korean by a repetitive selection method will be described again. Figs. same. The case where ambiguity occurs in FIG. 4-4 is also shown.

Hereinafter, an example of Korean will be described in detail for the sake of convenience.

In the case of Korean, the syllable consisting of "mother + mother" is about 50% (more precisely 54.011%) and the syllable composed of "mother + mother" is about 50% of the whole. Therefore, the transition from the consonant to the vowel ("jamotoje" or "jamo bond") frequency of the syllable consisting of "self + moi" and the transition from the vowel syllable consisting of " Quot; cap transition "or" cap combination "). If the syllable composed of "child + mother" is about 70% of the total and the syllable composed of "child + mother" is about 30% of the total, the mother tongue has a 30% The vowel is assigned to the same button and ambiguity occurs because it assumes that the first syllable is 30% ending with "child + parent", and puts a 70% weight on the mother's transition frequency (conversely, Consonants are assigned to the same button and ambiguity occurs because the first syllable assumes the case of 70% ending in "self + moh").

The frequency of hat transitions examined in the literature is as follows. There are 277 consonants (twenty-seven consonants) in 21 vowel (neutral) vowels in Korean, and there are actually 270 vowels in which transitions occur. The top 12, accounting for 51% of the total, and the top 48, accounting for 90% of the total. This large difference in transition frequency (coupling frequency) means that ambiguity can be greatly reduced through optimized grouping (consonant + vowel). In the present invention, only the transition of the vowel and the consonant displayed on the keypad need to be considered in the transition between the vowel and the consonant. It is easy to see that when combined with a vowel and a verb or percussion, the "control" presented in the earlier application intervenes to eliminate ambiguity.

In the case of the hat transposition to be considered for minimizing the ambiguity in the present invention, there are 100 cases because 10 basic consonants can be combined with 10 basic vowels displayed on the keypad.

The frequency of the surveyed children 's self - esteem is as follows. The following is a survey of the frequency of syllables consisting of only "self + mo". In the case of " child + mother + child &quot;, it is not necessary to consider here because it is considered in the mother transition frequency, and this is one of the important factors in the present invention. There are also 100 cases where the 10 basic vowels can be combined for 10 basic consonants displayed on the keypad.

Since the frequency of the mother-to-child transition and the mother-child transition is not a relative ratio value but an absolute frequency, it is possible to construct a table showing the frequency of the combination of consonants and vowels by combining them. The following table summarizes the frequency of mother-to-child transition and mother-to-child transition. As described earlier, the syllable composed of "mother + mother" is about 54% of the total, and the syllable composed of "mother + mother" It is about 46%, so you should put 46% in the frequency of the jogosjeon. In the table below, however, there is no significant difference between Korean and English, because the syllables composed of "mother + mother" or "mother + mother" occupy about half of each, .

In general, the problem of minimizing the ambiguity when applying the repetitive selection method through the keypad is said to be an NP-hard problem. However, the problem of minimizing the ambiguity that arises when applying the (simple / simple) repetitive selection method of one consonant and two vowels in a keypad in which a consonant and a vowel presented by the applicant are arranged in a pair is the assignment problem of a typical linear programming method This is also a great advantage of the invention of the applicant. In the end, the above table is a table (integration frequency table) obtained by integrating frequencies of the optimization problem to be mathematically modeled in the present invention.

In the invention of the prior application, assigning a group of alphabets to be assigned to each button is referred to as "grouping ", assignment of grouped alphabets to each button is referred to as" assigning " "And the pairing of the characters to minimize the ambiguity in accordance with this is called a" grouping problem ".

Let the suffix of each row be i and the suffix of each column be j, and the number of consonants and vowels to be assigned, that is, 10 is n, then the objective expression and the constraint are as follows.

Where each variable and coefficient

0 : i 번째 모음과 j 번째 자음이 그룹핑되지 않을 때

0: When the i-th vowel and j-th consonant are not grouped

     1: When the i-th vowel and j-th consonant are grouped

i 번째 모음과 j 번째 자음이 연속하여 나타나는 경우의 통합 빈도수를 의미

The integration frequency when the i-th vowel and the j-th consonant appear consecutively means

In the above equation, the objective expression is solved.

Likewise, a constraint can be used to solve it. Since the mathematical model of the problem has been established and the coefficients (transition frequency or coupling frequency) have been determined, solving the above problem can be easily solved using a commercial LP (Linear Programming) package. The result of solving the above problem is as follows. However, the result obtained by dividing the above integration frequency table used as a constraint factor of the program used by the applicant by 1/50.

However, even if you do grouping to minimize ambiguity, that grouping is not the best. Because the positional identities of the alphabets on the keypad are also important considerations.

Solving the problem to minimize the frequency of transition (or combination), you can find pairs of consonants and vowels that can minimize ambiguity. On the contrary, when the above problem is solved to maximize the frequency of transition, ambiguity occurs a lot, but the convenience of input is increased because the same button is pressed more frequently when the alphabet is inputted. However, there is a disadvantage that the user must know and cope with the occurrence of ambiguity.

To maximize the frequency of transition (combination frequency), place the vowels in pairs, input one consonant and one vowel, enter a confirmation button in syllable (in Korean), or select a confirmation control to confirm a syllable It can be said that it is very efficient. In this case, when inputting consonants and vowels that are not displayed on the keypad, subsequent controls can be assigned to buttons for which the confirmation control is not disposed, and subsequent controls can be selected according to the number of repetitions of the control button, thereby inputting all consonants and vowels without ambiguity It is possible to do. However, there is a disadvantage that the user must be forced to press the confirmation button in syllable unit. As indicated in the prior application, this subsequent control button can be applied to both the consonant and the vowel, so that one subsequent control button can be applied to both the succeeding consonant and the succeeding vowel. It goes without saying that the same is true even when the confirmation button of the syllable unit is not inputted.

To maximize the transition frequency (coupling frequency), solving the problem with the objective expression as "Max Z = ...", solve the minimization problem by adding the minus symbol ("-") to the coefficient (frequency) We can solve the problem of minimization by using the value obtained by subtracting each coefficient from the number. It can also be easily solved using the commercial LP package.

Although the combination of consonants and vowels does not consider all occasions where ambiguity arises, most cases (ambiguity) are pointed out, and suggestions for optimizing based on the frequency It is the "core" here.

Finally, the "key" of minimizing ambiguity with a mathematical model is rearranged. Then, 10 consonants and 10 vowels are grouped into pairs and placed on each button. Each button is used to select consonants placed on the keypad, and each button 2 In the method of selecting the vowels arranged on the taro keypad, the most cases where the ambiguity occurs are the hat-transfer (combination of the vowel and the consonant in the syllable consisting of "child + The consonants and vowels in a syllable consisting of two consonants and vowels are assigned to the same button, and based on this, a weighting is given to the frequency according to each type of transition, The "integration frequency table" to be used as a coefficient. It is very easy to use commercial programs to identify groups of consonants and vowels that can be solved by solving such a mathematically modeled problem.

This can be equally applied to languages such as Hindi and Myanmar, where one syllable is mainly composed of "+ Ma +" or "Ma + Ma +". For languages other than Korean, data on the frequency of transition (consonant frequency) of consonants and vowels can be obtained using existing data, and if there is no existing data, construct corpus appropriately so that the frequency of mother- And apply the method applied in the Korean example. In other words, as already explained in the Hindi, if the syllable composed of "mother + mother" is 70% and the syllable composed of "mother + mother" is 30%, the frequency of mother-daughter transition is 70% 30%. Also, in Hindi, there is a syllable consisting of only "moja", which may be ambiguous to be recognized as "mother + mother" (ie, regardless of the form of the preceding syllable) Quot; hat " or "zero hat combination") is 100%, so that the integration frequency table of the three cases can be obtained and grouping of consonant and vowel groups can be performed to minimize the integration frequency.

In the earlier case, in the case of Hindi, grouping 10 basic vowels and 9 representative consonants into pairs requires solving the problem of grouping 10 consonants and 10 vowels by adding phonetic (consonant) consonants. The frequency of the transition between the phonetic consonants and the 10 basic vowels can be set to "0".

4. How to use vowel elements in Korean

4.1.1 How to control tremors and tones

Korean vowel elements (ㅡ, ㅣ,.) Can be used. See Figures 4-5. In the present invention, nine basic consonants among the 10 basic consonants are assigned to the numeric buttons [1] to [9], and the vowel elements "-", " ㅣ ", and assign the vowel element". "To the [0] button. Various assignments are possible, but for convenience, the assignments and arrangements of FIGS. 4-5 are illustrated in the present invention. The arranged basic consonants and vowel elements may be placed at the positions of the reference grids and it is not necessary to apply the partial selection method to the selection of the arranged basic consonants and vowel elements.

In the control process of the tremor and the percussion, the "tremor control" and "percussion control" are arbitrarily assigned to the buttons arranged "ㅡ" or "ㅣ", respectively, and the remaining grids are arranged in a grid close to the reference grid. That is, the control is assigned to the button 2 and the sound and control controls are selected. You can also arrange a mute control (or shuffle control) on the button assigned to the sham sound control (or mute control) to select it with the three arranged buttons. As explained in the earlier application, "ㅅ" is not shrill, so "ㅆ" can be regarded as tense and shudder. Also, the sham sound control or the sound control need not necessarily be displayed on the button, and the user is required to know the input rules.

When the control of the sham sound control is selected as "{shake}" for convenience, and the control line input in the example of Fig. 4-5 is applied, b = {shake} + a = [*] + [*] + [1] . Similarly, ㄲ = {lull} + a = [*] + [*] + [1]. If you allow the slash control to be selected with the button 3 assigned to the Shuffle control, then ㄲ = {loudness} + a = [*] + [*] + [*] + [1].

In the present invention, the punctuation control and the shuffle control are assigned to the same button together with the alphabetic elements of the collection alphabetic elements, and the application of the repetitive selection method is not ambiguous because of the nature of Korean, the collection "ㅡ" This is because, in the example, entering the [*] button twice to select a sham sound control is not recognized as selecting two vowels "ㅡ" + "ㅡ". The same is true of the vowel "ㅣ". The vowel "ㅣ" appears twice in the word "courtesy" (eg [8] + [0] + [0] + [#] + [#] + [0] + [*] + [#] In this case the vowel alphabet element "." , So the "[#] + [#]" in this section is not a selection of the audible control, but a vowel. Because in the example, the vowel alphabet element "." Because the word can not be terminated, so the input [#] following it is a vowel. Since the vowel "ㅡ" never appears consecutively, there is no ambiguity, even if the button assigned to the vowel "ㅡ" assigns sound and sound control to the assigned button.

And, since nine consonants among the ten basic consonants are assigned to nine buttons ([1] to [9] buttons), the other one consonant is not allocated on the button. This will be referred to as "9-button dropout consonant" for convenience. It is possible to omit the control processing by considering one basic consonant of the ten basic consonants as a modified alphabet or a subsequent alphabet considering the similarity of pronunciation or shape. For example, if you do not place "d" on the button, you can think of "d" as a variant of "ㄴ" = [*] + [*] + [*] + C or d = [#] + [#] + c. In the example of FIG. 4-5, considering the similarity of the pronunciation and the shape, "he" is regarded as a modified alphabet (ump) of "ㅇ", so he = [*] + [*] + ㅇ or he = [* ] + [*] + [*] + ㅇ or ㅎ = [#] + [#] + ㅇ.

In this case, the controlled alphabet ("h" in the example in FIG. 4-5) would be one of the alphabets (b, k, d, he, o) . The basic alphabet of the alphabet to be controlled ("ㅇ" in the example in FIG. 4-5) is also one of the non-existent alphabets, so it is natural to add the convenience of alphabet input. The reason why the control processing of "ㅎ" is proposed is because the frequency of use is also the lowest among the alphabets which do not have sound and noise, and which do not have sound and noise. There is also similarity in pronunciation, and there is a similarity in the shape as well as the relationship between other equilibrium and falsification.

Here, in order for Korean to be used for memorizing telephone numbers and various codes, it is preferable that ten basic consonants (flat tones) are arranged in ten number buttons. Thus, you can place the "ㅎ" on a grid where you can additionally assign a "." To the assigned button ([0] in the example in Figure 4-5) and select "ㅎ" for that button. Because there are many cases where "." Occurs twice consecutively, it is necessary to select the third choice to avoid ambiguity by applying the iterative selection method. In this case, it is only necessary to recognize that the user can select "he / she" with only the corresponding button 3, even if "he is not physically placed on the third closest grid in the reference grid. This means that "H" can be input to the [0] button 3, but by arranging all of the basic consonants on each number button, it can be useful for various memorization.

In Figure 4-5, the consonants are shown in blue, vowel or vowel elements are shown in red, and numbers are shown in black to enhance the identities of the alphabets. A blue "ㅡ" on the [0] button indicates that "ㅎ" is implicitly assigned to the [0] button because "+ ㅡ + .

In other words, the consonant of 9-button disappearance can be regarded as a modified alphabet of a specific basic consonant and can be inputted by a control processing method, and at the same time, a vowel element "."

As described above, the 9-button declination consonant (for example, "heh") is put on a button such as "ㅡ" or "ㅣ" by using the property that "ㅡ" and "ㅣ" do not appear consecutively in Korean It is also possible to enter the consonant with the 9 button disappearance of the corresponding button 2. In this case, one of the punctuation control or sham control is "." , And the control assigned to the other button is selected. That is, it can be arbitrarily grouped into three groups of nine buttons, consonant consonants, dull control, and auditory control, and vowel elements (-,., And).

4.1.2 Basic consonant combination processing of hyphenation and repeated / selective processing

Even in the method using the vowel element of Korean, it is possible to process the hyphenation as a combination of basic consonants. Moreover, since the basic consonant is assigned to the number buttons in the method using the vowel element, even if the tones are treated as a combination of the basic consonants, only in the case of "otoki" <=> " Ambiguity (first ambiguity due to ambiguity between full codes) occurs. (In "oh" the "ㄷ" is the bell)

However, it can also be solved by providing an "index" to avoid this ambiguity. As a result, in case of inputting a hyphenation as a combination of basic consonants, only the shaking sound can be input by the control processing method, so that the input rule can be further simplified. The shudder control can be placed in an appropriate grid as described in the prior art. For example, in Fig. 4-1 or Fig. 4-2, the punctuation control is removed.

(Eg, a = [1], b = [1] + [1], ㄲ = 1) according to the number of times the button is pressed in the order of basic consonant, [1] + [1] + [1]). In this case too, the first ambiguity may arise as indicated in the prior application. Specific cases where ambiguity occurs are not introduced here. In this case, the basic consonant, tremor, and tune can be displayed on the button or only the basic consonant can be displayed. This is to select a subsequent alphabet (eg,,, ㄲ) by the iterative selection method.

Here, a method for displaying only the representative alphabet and selecting the remaining succeeding alphabet by the iterative selection method will be referred to as "concealed repetitive selection processing method" for convenience. Again, the ranking order of trueness and tremor can be in the order of basic consonant-trueness-tremor. For example, it is set as a (1st: reference grid position), ㄲ (2nd), ㅋ (3rd). That is, a = [1], ㄲ = [1] + [1], ㅋ = [1] + [1] + [1]. It can be seen that the consonants are treated as a combination of basic consonants (or concealment type iterative selection process) and the shouting is also selected by the concealed repetitive selection processing method.

In this case, it is possible to input natural number in the position of the user by making it possible to input with the number button 2 (combination of the basic consonants) at the input of the hyphen, have.

In addition, when you enter "ㅎ", you entered it with [3] button [0]. The relationship between "ㅇ" and "ㅎ" is similar to the relationship between shape and pronunciation (basic consonant) It is possible to increase the consistency of the usage method as a whole.

In this case, it is possible to input "he" at the same time, while allowing "h" to be input by using the [0] button 3 assigned with "he" , It is of course possible to input the tremor by the control processing method at the same time while inputting the treble sound into the button 3 (or 2) of the button to which the basic consonant belongs. If the user inputs the percussive sound by the control processing method, the system can identify the percussive sound without the ambiguity (full ambiguity between the full codes) at the percussive input, and if the basic percussion sound is input by the button 3 Ambiguity may arise. This is also true of trite.

That is, the user can enter the sound on the same keypad by the control processing method, or can input the sound by using the concealed repetitive selection method. For example, if you want to select the shaky control by using the [*] button 2 and simultaneously select the 2nd and 3rd tones of the basic consonant and input the "Khaki" *] + [*] + [#] + [0] + [1] + [1] + [1] + [#] ". In other words, the first "ㅋ" is input by the control processing method, and the second "ㅋ" is input by the iterative selection method. Likewise, it is possible to make "Cave" by "Cave = [1] + [#] + [#] + [#] + [0] + [1] + [1] + [#]".

The selection order of the percussion and the percussions can be set according to the user's convenience by inputting the percussion and percussions by the non-concealment type repetitive selection processing method or the concealment type repetition selection processing method.

4.1.3 Mixed use of method of using pair of basic alphabet and method of using vowel element

The method of utilizing the vowel element can be seen as a simplification of the keypad of Figs. 4-1, 4-2, and 4-3, and can also be compatible with the alphabet input methods of the prior art. In other words, the alphabet input method of the present invention can be applied to the keypad in which 10 basic vowels are additionally displayed on each button, and furthermore, in the entire display keypad showing basic consonants, basic vowels, extended vowels, The input method of the application can be applied.

In the example of FIG. 4-2, the punctuation control and shuffle control are assigned to the [*] button or the [#] button, and even if they are not displayed, By using "ㅣ", it is possible to selectively use a method using a vowel element and a method using a pair of basic characters. For example, in FIG. 4-5, eight basic vowels other than the vowels "ㅡ" and "び" existing as vowel elements are assigned to eight buttons among the nine buttons [1] to [9] So that the basic vowel can be selected for the button 2 assigned to the basic vowel. Likewise, a control processing method or an iterative selection processing method can be applied to the input of the tremor and hyphenation. For example, suppose that eight vowels except "ㅡ" and "ㅣ" are arranged as shown in Fig. 4-2 in addition to Fig. 4-5. If you enter the word "vassin" [3] + [3] + [7] + [#] + [2]. According to the convenience of the user, the vowel "a" of the "a" applies an iterative selection method, and the vowel "v" of the "new" is input using the button on which the vowel elements are arranged. Other methods of vowel input apply within the same word, but do not require input mode switching.

In addition, eight additional vowels are assigned to the buttons [1] - [9], and two basic consonants (for example, b / D or ㅇ / ㅎ etc.) can be put together and the iterative selection method can be applied. The ambiguity that may arise in this case can be overcome through the "index" which will be explained next.

5. How to overcome ambiguity through indexing

When applying iterative selection method, ambiguity may occur because several words are represented by a single code. In the input example of FIG. 4-1, it is pointed out that there is ambiguity that "Koi" can be recognized as "Koi" and "Koi" as "Koi". However, the word is usually entered on a word-by-word basis. For example, there is the word "very" but there is no word "verb". In Fig. 4-1, both have the same code value. Accordingly, the terminal (client) or the server side prepares and registers an index for a specific keypad and words that may cause ambiguity about a specific alphabet input method. If "very" or "very long" is entered as the correct word and "very" is registered as the correct word in the index when the two can not be distinguished by the time delay or the like, Quot; target word ") is" very great ". This is only applicable when the system has ambiguity that can not be distinguished, and it should be followed when it is possible to distinguish by the time delay value defined by the system (terminal side or server side system) or the user defined time delay value . In other words, if the user intentionally breaks (by using a delay or blank, the right-hand side button, or some other specific button) and enters the word "this word", the word is the target word, "

The way to prepare the index may be to register only the correct words (e.g. "very" in the example) for the words where ambiguity can occur, or only the correct words (in the example "high"). It is also acceptable to register both the correct word and the correct word, and the system only needs to know whether the word in the index is the correct word or the correct word.

This can be applied in all cases where the iterative selection method is applied to the keypad. For example, in the input method of Samsung Electronics in Korea, ambiguity such as "Country <=> Guka" occurs, which can be similarly applied here. In addition, similarly to FIG. 4-1, when a pair of alphabets is placed on each button and a syllable completion button is pressed in units of syllables (letters) while allowing selection of one consonant, two consonants, three consonants and one vowel . &Lt; / RTI &gt; When the user inputs "very", the user can refer to the index at the moment when the word is terminated (for example, a blank space, etc.) to make it "very" even if a temporary "

In this case, when the index of the word exists in both the client side and the server side, the client side index is first searched to identify the correct word, and when the identification is unsuccessful, the server side index is searched secondarily, . &Lt; / RTI &gt;

The distinction between units of a word can be identified by the elements that distinguish words from words as one can think of. For example, between whitespace and space, between word start and space, between whitespace and end of input, between whitespace and mode switching, and so on. Since the correct word is determined by reference to the index, the index reference is made and the correct word can be determined when an element that distinguishes the word is input.

This can be applied to all cases where ambiguity occurs by applying the iterative selection method. For example, ambiguity may arise when the consonant belonging to the same button is in consonant and primitive in Samsung Electronics' method currently used in Korea. "Country" <=> "Guka" is an example. When entering a code for each alphabet, the syllable is entered without recognizing the unit of the syllable (character), so in many cases it is unconsciously entered as "Guka" by entering "Country". In this case, if neither of the two words can be known by the time delay, the system (terminal or server) can find the target word by referring to the index. However, in this case, even if the "ㄱ" and the "ㄱ" beginning of the "station" are pressed successively, in most cases the target word is often "country" It is also effective to identify the target word by referring to the target word.

It is also clear that this is applicable not only to the Korean language but also to all the languages where the iterative selection method is used. For example, "AB" or "BA" is entered when inputting [2] - [2] - [2] in English input or in English mode on another language keypad. Is registered with the correct word in the index, it can recognize it and provide it as a target word to the user. If a plurality of words in which ambiguity occurs are registered in the index with the correct word, the user can be provided with a frequently used word primarily, and the user can finally determine the target word.

If there is ambiguity about the input of a certain word, if all the words corresponding to the input are recognized as correct words even if referring to the index, the user may be given feedback by an appropriate method (visual or auditory) .

A method for allowing the user to confirm a target word is to arrange a plurality of words recognized as correct words in the display window in order of frequency of use (or priority order), and to scroll down or down using the number buttons corresponding to the displayed order So that the user can confirm the target word. Another method is to display a word having a high frequency of use next by selecting only a word having a high frequency of use and selecting a control (hereinafter referred to as "next word control" , And if it is not a target word, the next word control can be similarly selected again so as to continuously search for the target word. In this case, it is possible to search for the target tare and make the target word determined by inputting any other button (for example, selection of another alphabet, or blanking, mode switching, or the like, .

The selection of the next word control can be applied to both the " partial selection method "or" repetitive selection method (reference / simple) "described in the prior application. If the next word control is positioned at the position of the reference grid of a particular button, the next word control with that particular button 1 will be selected.

6. Simple code utilization method and shortening input method / parallel input method

6.1 How to Generate Alphabetic Simple Code

When accessing the information system using the information communication terminal, the input of the alphabet is essential. Alternatively, the alphabet to be input can be input as a numeric code. In a compact information communication terminal, a keypad type interface is often employed. The code used here refers to all kinds of codes, such as a telephone number, a stock code (listed company) code, a city code, a department code, a train station code, and a bank code. The advantage of encoding and entering various names is that input can be simplified.

The information communication terminal includes all types of information communication terminals such as a PC, a mobile communication device, a smart phone, a PDA, a bidirectional character transmission / reception device, and an ATM (automatic teller machine). It also encompasses terminals that do not have a communication function, such as an electronic notebook. The information system includes all types of systems such as ARS as well as systems that can be visually accessed through the GUI. Also, the system is narrowly referred to as a server-side system, and broadly includes a client software of the terminal corresponding to the server system.

It is useful for memorizing various codes by using the alphabet arranged on the keypad. When used for memorizing a code, there may be a method by simple naming, initial naming, and full naming. A summary of the contents is as follows.

Simple naming is a code that specifies a number associated with a word or phrase (a word or phrase collectively referred to below as a "phrase") that you wish to encode. For example, in the case of Korean, in the case of a company name code, "1799" associated with the code "a", "b", and "i" In this case, it is possible to make a simple code of a specific word easier to recognize by displaying the a, b, c, and c associated with the simple code "1799 " in the" added electronic ", and furthermore, You can also extract it. In the case of simple naming, the code associated with an alphabet belonging to a word to be coded is determined by a code, so it is not necessary to set the code of the "added electronic" in the example to "1799". For example, the simple code of "stock" can be a simple code with values associated with ell, l, l, and d. In the case of additive e, there are other examples, such as "1729" Quot; 1749 "associated with a, b, c, or i, or" 13294293 "associated with the entire alphabet that constitutes" added electronic ". For convenience, it is referred to as " full associative simple naming ", in which it is referred to as " full associative simple naming ", and assigning simple codes in association with some alphabets of a specific phrase. In any case, simple naming (ie, simple code) can be viewed as specifying the code associated with the alphabet that makes up the phrase in phrase units. This can be applied to languages other than Korean. For example, in "captain", "2786" associated with the consonant "CPTN" can be a simple code, which is some associated simple code, which will be referred to as "consonant association simple code" for the sake of convenience.

Words as well as phrases can also be coded by simple naming. "8314" mapped to ㅇ, ㄷ, ㄱ, 활용 can be used as a simple code by using a letter (syllable) that best implies meaning in the phrase "where to go", which is an example in the prior application. In English, you can use simple code "3886", which is associated with d, t, t, and n, which has a sonata in "date tonight"

Initial naming is a special case of some associative simple naming. In Korean, the initial naming may be a method of designating a number mapped to the initial (consonant) on the basis of a syllable (letter) as a code. This is referred to as "syllable-based initial naming" for convenience. In the case of "added electronic ", the initial code by syllable reference initial naming becomes" 1799 " associated with consonant initials of each syllable (letter). Syllable-based initial naming can also be applied to languages other than Korean. For example, in the case of English, the initial code by the syllable reference initial naming of the word "entertainment " may be" 3886 " associated with e, t, t and m. The syllable-based initial naming can be more useful in the case of Korean, where one syllable forms a single letter.

Likewise, initial naming is possible for phrases, which can be initialized to "81", which is associated with the first alphabet, o, a, in the phrase "where to go" for example in the earlier application. In the case of English, the initial code for the word "initial" with the words "dance with the wolf" in the preamble is the initial code "3979" associated with d, w, t, Word-based initial naming can be useful in all languages when a code is assigned to the entire phrase.

It is also referred to as "simple code" or "short code" for the sake of simplicity throughout the simple code (the entire associated simple code couple related simple code) and the initial code (syllable initial code, word based initial code) . The entire associated simple code, consonant-associated simple code, syllable-based initial code, and word-based initial code can be used universally because of their regularity in code generation. Can be easily used.

Full naming is the input value of a phrase to be coded by a specific character input method. Therefore, it can be changed according to the character input method applied, and it can be regarded that a numerical value corresponding to a certain phrase is code by alphabet unit. In the case of "Seoul", which is an example from the earlier application, the full code by the partial selection method (mentioned in the earlier application) based on FIG. 4-2 becomes "7745888944". The full code by the reference iteration selection method (mentioned in the earlier application) becomes "7448884 ". If you apply a different keypad from Figure 4-2 or apply another alphabet entry method, there will be a corresponding full code value.

6.2 Simple code generation method

In a meaning like Chinese, there is a need for a method of reasonably coping with a large number of letters with buttons on the keypad. One way is to match the English pronunciation of Chinese with the alphabet on the English keypad. Another way is to use the keystroke of the kanji, which is the signifier, to map with the key on the keypad.

자 형을 이루게 된다. 또는 1 성조 ~ 5 성조를 각각 [1] ~ [0] 의 10 개 버튼에 각각 순서대로 2 개의 버튼에 대응시킬 수 있다.All the letters in Chinese have five lines. It is one of the three stars (St. Goggia -), two stars (St.Goggia), three stars (St.Goggia), four stars (St.Goggia), and silent letters. It is possible to correspond to two buttons on each of the five keystroke keypads. In this framework, various methods can be deployed. For example, one set is made to correspond to the [1] button and the [2] button, the two sets are made to correspond to the [3] button and the [6] button and the triplet is made to correspond to the [4] , The four-tones can be made to correspond to the [8] button and the [9] button, and the unsound tones can be made to correspond to the [5] button and the [0] button. This is because the first to fourth keystrokes are arranged on the up / down / left / right buttons on the keypad for convenience of use. Different colors for each of these button pairs can provide a better visual effect. [1, 2] [3, 6] [4, 7] [8, 9] in the up,

It becomes a form. Or one tone to five tone tone can be respectively associated with the two buttons in order of the ten buttons [1] to [0], respectively.

Here, it is a problem to determine whether the character having a single character is the character corresponding to the button [1] button or the button [2]. There are many ways to do this. For example, there is a method of distinguishing by the stroke number (that is, one of the methods for determining the complexity of letters). If the number of strokes of one character within a word or sentence is less than a certain number of strokes (for example, 5 strokes), it is judged to be a character corresponding to the [1] button (a small number of buttons [1] and [2] Or a character corresponding to the [2] button (a large number of buttons among the [1] button and the [2] button). 5 strokes are used as the judgment criteria. This is not an average stroke number of a commonly used (kanji) (kanji) used in the present invention, but the number of characters whose number is less than a certain stroke number is about half of the total number of strokes Can be set to a predetermined number of strokes based on a half of the total.

The method of judging the complexity of the letter is proposed by the stroke number. Another method is to judge the number of element letters. An element character is a character that can be recognized in one Chinese character. For example, the castle is composed of two element letters (soil + formation), and the prohibition consists of three element letters (tree + tree + indication). Therefore, if the number of elements is equal to or smaller than a certain number of element letters (for example, two) among the two buttons corresponding to the same tone, it is determined to be a letter corresponding to a smaller number of buttons. It can be judged.

Figure 5-1 shows the relationship between Chinese characters. The spread code is commonly used, and the spread code of FIG. 5-1 is also used in the present invention. An example of a keypad in the present invention Fig. 5-2 shows an attribute code on a keypad button. In the example, the 1 symbol is assigned to the [1] button and the [2] button. If the complexity (number of strokes or element letters) of a character is less than a certain level (for example, 5 strokes and 2 element characters), the 1 button is displayed smaller and the 2 button is displayed larger. So that it can be easily and intuitively judged. Referring to FIG. 5-2, a result of coding some words corresponding to the keypad is shown as follows. In the following example, we applied the stroke number "5 strokes" based on the complexity of the letters. The letters above the letters are the strong letters.

If different words in your system generate the same code, you can avoid redundancy by appending a sequence number after the word string. For example, if a character having a numeric code such as code 7612 of Baekgo Corp. exists in the system, the code is generated and interpreted by attaching a serial number to Baekwoongji 1 with 76121.

When a character is input by the user in order to designate a simple code based on the tone, the system may extract a simple code corresponding to the input character according to a predetermined simple rule generation rule defined in the system, and display the extracted code to the user. The difference from the case where the Chinese character is a sound character is that the system does not need only the mapping information of the letter and the number but the dictionary and the stroke number (or the number of element letters) by referring to the dictionary.

In the present invention, a method of mapping Kanji (Chinese characters) to buttons of a keypad based on Chinese character characteristics and character complexity is proposed. Due to the nature of Chinese, it is intuitively convenient to arrange the current keypad arrays in two rows and five rows by assigning five buttons to two buttons. For example, if you place the [1], [2] buttons on one line of the keypad, the [3], [4] buttons on the second line, and the [5] and [6] buttons on the third line , The [7] and [8] buttons are arranged on the fourth row, the [9] and [0] buttons are arranged on the fifth row, and the [*] and [#] buttons are arranged on the sixth row. The two buttons in each row are assigned 1, 2, 3, 4, and 0, respectively. Based on criteria such as the complexity of the letters, It can be decided whether or not to judge it by the letter. The arrangement of the buttons of the 2 * 6 keypad may be the same as that shown in FIG. 5-3. In this case, it is possible to assign each tone to the two buttons of each row and judge whether the character corresponds to the button of the first column or the second column according to the complexity.

If only one standard is not used and more than one method is used, the generated code value will be different as the keypad button assigned to the tone is changed. Thus, the conversion between a generated code by a certain method (for example, a code by a 3 * 4 keypad in the present invention) and a generated code by another method (for example, a code by a 2 * 6 keypad in the present invention) Is required. The conversion may occur at the server side or at the terminal side client software. In any case, it can be seen that the conversion takes place in the entire system (server + client), and if you know what method is applied in the whole system, you can re-convert it to the necessary code. For example, if the code value of the People's Daily according to Method 1 is input and the necessary value in the system is the code value according to Method 2, the system can obtain the code value according to Method 2.

If you do not want to generate a code in a department, but want to generate a code in a department, only the department is highlighted by entering the department in combination with a specific function key when inputting, and only "76" is generated for the department . Furthermore, when it is desired to generate a code based on only a part of characters (for example, currency conversion) (for example, for duplication of codes), only the conversion is displayed in the character, . That is, in this case, the simple code of the bookkeeping corporation (indicated by only the white currency corporation) is "7312" instead of "7612".

As for the Chinese input method, it is a general form to input the English corresponding to the Chinese pronunciation and to select the corresponding Chinese character when the Chinese character is converted by using the "Chinese character conversion key "

For Chinese, the full code can be determined based on the English pronunciation of Chinese. Furthermore, when there are a plurality of words having the same pronunciation, it is possible to set a full code by summing the pronunciation of English pronunciation, the Chinese character conversion key, and the target word among the same pronunciation words. In the example of the present invention, the Chinese character conversion key at the time of inputting on the keypad is indicated by [*] buttons in FIGS. 5-2 and 5-3. In the present invention, the conventional method is used without specifically mentioning the English input method.

In the present invention, it is necessary to provide a "specific function key" for simple naming of Chinese. In other words, if you enter the English alphabet, enter the Chinese character conversion key to select the desired Chinese character, and then use a specific function key for simple naming (here simply referred to as "simple code key"), Are displayed in order, and among them, element letters for simple code generation can be selected. In the example of the present invention, a simple code key [#] button is used.

In the above example, if you enter a simple code after inputting a currency from a bank, the currency letter itself such as currency, conversion, and shell, and the element letters constituting the currency are displayed in order. If the second currency is selected, And the corresponding simple code is recognized as 3 in the system. The recognition of simple currency 3 for the currency denominated with the emphasis only is recognized as 3 immediately after input and stored in the system so that it can be used later or interpreted from characters.

For naming code in Chinese, it is necessary to have a Chinese dictionary in the whole system (client side or server side). That is, when a user inputs a named character, the system can map the named character to a numeric code by referring to the dictionary, the stroke number (or the number of element characters) from the dictionary, and the like. The dictionary assumes that the Chinese characters can be mapped to the numbers on the keypad, and the number of strokes or element characters. The user or system administrator should be able to add words that are not registered in advance and to store relevant information necessary for the mapping of the images. However, if the user does not have a Chinese dictionary in the entire system, the user should be able to input mapping information such as a tone when inputting a word as a named character, or input a numeric code corresponding to a character.

In the case of Chinese, generating a simple code based on a tone is advantageous in that a single numeric code can be intuitively corresponded to each character without generating a simple code based on English pronunciation. In the case of Chinese, the company name and city name are all made up of a certain number of letters. The length of the simple code based on the tone is consistent with the number of characters (the number of characters), so that the length of the code can be fixed. There is also an advantage that it can be used on a keypad that is not.

This can be applied to all languages that have a long history, such as Thai, Myanmar, and so on. Every syllable in Thai has a long tone. There are five main tongues of Thai language: Pyeongseong, 1, 2, 3, 4. Therefore, as in the case of Chinese, it is possible to correspond each tone to two buttons of the keypad. And, when one tone is associated with two buttons on the keypad as in the case of Chinese, it should be determined which one of the two buttons corresponds to a certain criterion such as the number of strokes or the number of element letters. In Thai, there are two kinds of vowels combined by syllable, short vowel and long vowel, so it can be said that it corresponds to a small number in the case of short vowels and a large number in case of long vowels.

It is also possible to express five consecutive expressions according to the presence or absence of consonants, vowels and vowel sounds without explicitly marking the consonants (tense tense) (Tangible). The Thai consonants are divided into 9 Chinese characters, 10 high consonants, and 23 author tones, and even in the case of the tongue tongue with the same tongue sign, it may be different depending on the type of consonants. Therefore, it is possible to correspond to the two buttons on the keypad, that is, the case where the four flag signals are added regardless of the actual feature, and the case where the flag is not added, You can set a simple code. This is referred to as a "simple code based on a syndrome code".

In the case of Myanmarese, there are three main tongues: the first, second, and third. All of the three castles are marked by their signatures. Therefore, each button can correspond to the three buttons [1] - [9]. For example, one syllable corresponds to the first row of buttons ([1], [2], [3]). One of the criteria for dividing the same syllable into three parts is a syllable without a seed sound (eg, a child + a mother), a syllable with no first consonant and a seed sound (eg, a mother), and a first consonant and a seed And a syllable (eg, a character + a modifier). For example, if a syllable is a syllable of one syllable, it can be regarded as corresponding to one of the buttons [1], [2], and [3] , The syllable is associated with the [1] button. Since every syllable in Myanmar has an ephemeris, and the syllable composition rule is mechanically known, there is an advantage in that it can mechanically generate simple code based on the base line for all words.

6.3 Unique Simple Codes

In the case where the decoding of the simple code can be performed at the client side (that is, when the client side has a specific word and a simple code value corresponding to the specific word), the word corresponding to the inputted simple code is transmitted to the server side . Even if the client side can decode the simple code, if the server side requires simple code according to the nature of the application, the simple code itself (that is, the numerical list) You can interpret it. This is because the decryption of simple code can be done on the client side or on the server side.

When a simple code is defined and used for a plurality of phrases, there may be many phrases corresponding to the same simple code. The ambiguity that can occur between simple codes is called "second ambiguity" for convenience. In this case, it is possible to create and store a unique code value by adding a serial number to a simple code having the same value in the system. However, since a user mainly uses a simple code associated with a certain phrase, a second ambiguity occurs. In such cases, it is natural that the system should be able to recommend such phrases to the user according to the usage priority. In the case of having different words and having the same simple code, serial numbers are assigned to the simple codes according to the priority according to the frequency of use of the phrases in the system, so that the serial number can be used as a priority for recommending to the user. Of course, it is not necessary to attach a serial number, but the system may have the priority information separately.

For example, if the simple code of the syllable reference initial code "9196" and the simple code of the " sovereign information "are the same as the syllable reference initial code" 9196 " And the serial number can be used as a priority to recommend to the user. If the frequency of use of the "stock information" is high, priority may be given to it to set "stock information" = "91961" and "stock information" = "91962". The simple code generated by adding the serial number is referred to as "unique simplified code" for convenience, and the simple code having redundancy without serial number is simply referred to as "simple code" "

6.4 Examples of using simple code

An example of a simple code (syllable standard initial code) assigned to a city name is as follows. This can be useful in railway information systems and so on.

. Seoul: 78, Suwon: 78, Daejeon: 39, Shintanjin: 739, ...

Since the initial codes of the syllables in Seoul and Suwon are the same, in the system, the simple codes can be uniquely identified as "Seoul = 781" and "Suwon = 782" If the user sends only "78" to the system, the system will give the appropriate feedback (eg, provide a list of Seoul and Suwon) or let the user choose between Seoul and Suwon. If the user recognizes this from the beginning and inputs "781", the system can recognize it as "Seoul".

If the server side system does not require the simple code "78" but needs the word "Seoul" itself, the client side can interpret the simple code "78" and send "Seoul" to the server side. Alternatively, even if the client side can interpret the simple code, if the server side needs the simple code itself according to the nature of the application, the input simple code itself can be sent to the server side.

The following are examples of securities stocks (listed companies). This can be useful in various securities information systems.

. Donghwa Pharmaceutical = 3098, Digital Shipbuilding = 39397, Hanhong Freetel = 83643, ...

Here, for example, in the case of "digital shipbuilding", "c, i, y, x, x" used as a basis of the syllable reference initial code is highlighted to give a better visual effect to the user.

An example of a bank code is: This can be useful in ATMs and various financial information systems.

. Kookmin Bank (Bank) = 14, Han (Bank) = 82, ...

Here, it is obvious that the user can input the simple code defined above by interpreting it on the client side (terminal) side and displaying it to the user. This will be referred to as a " short input method ", followed by a detailed description in conjunction with the "parallel input method ".

6.5 Automatic reassignment of priorities according to selection frequency

Furthermore, if the number of times that a particular user selects "sovereign information" is markedly higher than the priority of the first "securities information" and "sovereign information" respectively, the priority of the "sovereign information" It can be adjusted to be higher than the priority of "stock information". There are a variety of methods as described, but you can achieve this by changing the serial number. If priority information is separately stored in the system, it is possible by changing the priority information.

The criterion for determining whether the number of times the "sovereign information" is selected is remarkably large may be determined by the system or may be (re) specified by the user. As an example of such a judgment criterion, if the selection is made differently from the predetermined priority of 8 or more out of 10, the existing priority can be automatically corrected. Depending on the option, the user may be asked to confirm the correction.

6.6 Simple Code Automatic Assignment and Simple Code Relevancy

In particular, since the consonant-related simple code, the syllable-based initial code, and the word-based initial code in addition to the entire associated simple code have regularity in the simple code generation as described above, when a user designates a simple code for a specific phrase, , A simple code corresponding to a specific word can be automatically extracted and stored in the system. In addition, since the alphabet associated with the simple code is highlighted, the convenience of use can be enhanced. In English, the alphabet associated with the simple code is highlighted, which can be highlighted using capital letters.

Also, in the prior art, "short input method" and "short / full parallel input method" have been proposed. The simple code for the shortcut input can be defined in the system, the user can change it, and the user can also specify a simple code for a new phrase.

In defining a simple code for a new phrase, simple code generation rules such as a full associative simple code, a partial associative simple code, a consonant related simple code, a syllable standard initial code, and a word standard initial code introduced in the prior application can be utilized. For example, if a user wishes to use a word-based initial code as a simple code in generating a simple code for "dance with the wolf," enter "dance with the wolf" in the simple code generation mode, The word standard initial code "3983" should be entered. Likewise, in generating a simple code for "stock information", if the syllable reference initial code is to be used as a simple code, "stock information" should be input in the simple code generation mode and "9196" should be input.

However, if a user designates a simple code for a specific phrase, a simple code desired by the user is stored in the system and a phrase for generating a simple code is input, so that a simple code Can be automatically designated. In the above example, it is set in the system that the syllable reference initial code is used, and the simple code for "stock information" can be automatically designated as "9196" by inputting only "stock information".

In the case of English, capital letters can be used to indicate the alphabet to be used as a simple code. Therefore, it is possible to designate the simple code assignment method to use upper case letters as simple codes, and when inputting "DaTe ToNignt", "3886" corresponding to upper case letter DTTN can be designated as simple codes or "ToNignt ShoW" Quot; 8679 " corresponding to the capital letter "TNSW" can be automatically designated as a simple code upon input.

6.7 Shortening Input Method and Parallel Input Method of a Word Using Simple Code

The simple code (the initial code is a special case of the simple code, so it is included in the simple code unless otherwise noted) is recognized as a phrase corresponding to the simple code in the system (client side system or server side system) It is possible to process. Therefore, it is natural to recognize a word corresponding to a specific simple code and display it again to a user, and to use it for inputting a word.

In fact, in the foreign alphabet input method, an index giving a "whole associated simple code" for each word is stored in a terminal (client side system), and when a user inputs a code, So that the character input system is implemented. For more information, visit http://www.tegic.com and http://www.zicorp.com. This method will be referred to as "full associative shortening input method" or "foreign method" in the present invention for convenience.

Compared with the alphabet input method on the keypad of the applicant, the alphabet input method of the applicant is given a unique code in alphabetical units and the target alphabet or target phrase is inputted by the full code , And the foreign method described above is to assign the entire associated simple code in units of words and input the target word by the simple code.

The disadvantage of the foreign method is that only a predefined word can be inputted by assigning a code in a unit of a word, a case where a target is inputted by using a toggle button or a moving button The fact that the input is not easy by selecting and confirming the words, the non-target words can appear temporarily on input, the system takes up a lot of storage capacity, and the implementation cost is high.

Here, it is pointed out that simple codes (some associations or entire associations) can be assigned to common phrases (concepts that include common words or common phrases), and target phrases can be entered using simple codes. The simple code for the common phrase may be predefined in the system and provided to the user, or the user must be able to designate it arbitrarily. Alternatively, the user can arbitrarily modify the simple code defined in the system. The user can arbitrarily designate a simple code value for a specific commercial word.

In the present invention, a method of inputting a target phrase using a simple code (including a partial associated simple code, a fully associated simple code, and an initial code) is referred to as a "shortened input method" for convenience and a method of inputting a target alphabet by a full code Quot; full input method "in preparation for the short input method for convenience. Also, as described below, the short input method and the full input method can be applied in parallel, and the method of applying the short input method and the full input method in parallel can be referred to as a "short / full parallel input method" Quot; input method ".

The ambiguity caused by the use of the iterative selection method among the full input methods that give a unique code in alphabetical units and input the code to input the target alphabet is referred to as "first ambiguity" or "alphabet ambiguity" for convenience . On the other hand, there is ambiguity that there are several different words for the same code in the way that the code is given to all the words as in the foreign method and the target word can be inputted through this code. Ambiguity "or" ambiguity ". In the present invention, simply ambiguity means first ambiguity.

If there is no simple code corresponding to the input value, it is determined that the input code is converted to the full code in the secondary code (for example, It is possible to construct a scenario such as recognition (that is, applying a full input method in a secondary way), and conversely, it is checked whether the input value is primarily a full code (that is, , And if the full code can not be formed, it can be recognized as a simple code (that is, a secondarily shortened input method is applied). The interpretation of the input value as a simple code can be regarded as applying the "short-cut input mode" as the basic input mode, while conversely, the first full code interpretation is the "full input mode" as the basic input mode As shown in Fig. It is desirable that a user who mainly uses a common phrase in a character input first applies a short-cut input method (that is, a short-cut input mode is used as a basic input mode), and a user who does not use the full- That is, the full input mode is used as the basic input mode).

In this case, when the basic input mode is set to the full input mode, since the input values are primarily regarded as full codes, the input values can form a full code even when the simple code is input. A word other than the target word can be input. For example, in FIG. 4-2, when the reference repetition selection method is applied by the full input method, the simple code of the word "corn" is set to "877" (using syllable reference initial code) Since it is regarded as a full code, it can be recognized as "F". This happens when the first and second letters of the second letter correspond to the same button, such as "corn", "corn", "no limit", "warr", "excellent number", " Conversely, when the basic input mode is set to the short-cut input mode, since the input values are primarily regarded as simple codes, they can be recognized as words other than the target words even when full codes are input. That is, the ambiguity between simple code and full code is called "third ambiguity" for convenience.

This third ambiguity can be overcome by a toggle method or a list selection method similar to the existing method. Or alternatively, it may be possible to switch from the full input mode to the short input mode or from the short input mode to the full input mode over a word before inputting the input value in which such ambiguity may occur. It is possible to input a katakana word in hiragana mode or a hiragana word in katakana mode by selecting the word "hiragana / katakana conversion control" with the "ah / ah" control as presented in the applicant's earlier application It is similar to that. For example, if the default input mode is full input mode, the system will recognize it as a simple code for the input value after selecting it with the "short / full" control and refer to the index The target word can be provided to the user. Similarly, when the short-cut input mode is used as the basic input mode, the input value after the selection of the "short / full" control can be recognized from the beginning as a full code and processed. The "short / full" control may also be pre-input or post-input for the target word, but in this case it may be convenient to pre-input.

In order to eliminate the first ambiguity, the determination of whether the input value is a full code or a simple code when applying the parallel input method may be performed word by word as referring to the index, It may be judged whether it is a simple code.

When the parallel input method is applied with the full input method as the basic mode, it is checked whether the input value forms a full code for each input of the code, and the input value is judged as a simple code when it is judged that the full code can not be formed The efficiency of the parallel input method can be doubled by referring to the simple code index and displaying the corresponding phrase to the user. In the same way, when the parallel input method is applied to the basic mode, the input value and the index are compared with each other. When the input value is compared with the input value in the index, It is possible to perform processing by judging by the full code of This implies that the third ambiguity occurring in the middle of the input can be removed at the beginning of input by applying the rules in each full input method. This can be applied to the case of using the alphabet input method not shown in the prior application as the full input method. Based on the full input method (reference repetition selection method, partial selection method) presented in the prior application, for example,

In case of Korean, for example, when the reference repetition selection method is applied based on FIG. 4-2 as a full input method, the second input value and the third input value of all syllables by the full code must always have the same value If this condition is violated, the input value can be judged as a simple code and processed. If it is allowed to process a pair of consonants with a combination of basic consonants, a judgment criterion can be applied accordingly. This is applicable in all cases where the standard iterative method is applied.

Also, in all languages, when applying the partial selection method as a full input method, two input values correspond to one alphabet, and the second input value for the first input value of the two input values is limited . For example, in the case of English, if only the left and right straight line combination is used as shown in FIG. 1-1, if the number is not selected by the partial whole selection method, the buttons ([1], [2] ) Is used as the first input value corresponding to one alphabet, the value that can be inputted as the second input value is also the button ([1], [2], [3]) of the first row. Similarly, if the button ([4], [5], [6]) of the second row is input after [2] + [1] is input, the next value to form the full code is also the second row ([4], [5], [6]) of the button. As soon as the input value violates it, the system regards the input value as a simple code and recommends the word corresponding to the simple code to the user according to the priority. If the partial selection method is applied to FIG. 4-2, there is only [1] or [2] button next to the input of the first [1] button in order to form a full code. If it is determined that the input value is not a full code, it is determined that the input value is a simple code, and the target word corresponding to the input value can be recommended to the user according to the priority by referring to the index. If the four alphabets P, Q, R and S are assigned to the button [7], as shown in Figures 1-3, one of the four alphabets, as indicated in the earlier application, In this case, the button [7], [8], or [9] in the third row can be used for the next button when the [7] button is input to form a full code for one alphabet, Only the button of the adjacent combination ([4] button) can come in. If it is contrary to this, the input value can be processed as a simple code. This is applicable to all languages when applying the partial selection method presented in the prior application.

In the case of FIGS. 4-5, since only one basic consonant is assigned to each button, when using a syllable-based initial code which is commonly used in Korean as a simple code, even when applying the shortcut input method and the full input method in parallel, There is good characteristic that can input without ambiguity. In other words, when the user inputs a syllable-based initial code when the parallel input method is applied, since the input value can not be a full code from the second input (when inputting by the control processing method), the simple code index It is possible to search for and recommend appropriate words according to the priority to the user. The same is true for full code input.

As an example of the above, it is one of the "core" of the present invention that it is possible to judge whether the input value is a simple code or a full code in the middle of the input when applying the parallel input method. This applies not only to the use of the full input method proposed by the applicant but also to the use of other full input methods. In particular, the full input method proposed by the applicant has a good characteristic of easily knowing whether the input value is full code when the parallel input method is applied as shown in the above example.

Also, as mentioned in the applicant's earlier application, interpreting simple or full code may occur at the client side or at the server side. In looking up an index to overcome the first ambiguity (alphabetic ambiguity) in the prior art, the scenario referring to the server-side index by referring to the index of the client side primarily is used for interpreting the simple code or the full code Can be applied. Conversely, it is also possible to refer primarily to the server-side index and secondarily to the client-side index. Further, the input value is firstly interpreted as a simple code, firstly referring to the index on the client side, secondarily referring to the server side index, and if the simple code for the input value can not be retrieved, However, if the client side interprets it primarily, and there is no such interpretation function on the client side, it can be interpreted secondarily on the server side. As another example, it is also possible to interpret the input values primarily as simple codes, referencing both the indexes on the client side and the indexes on the server side, providing them to the user, and allowing the user to select the target word. Similar variations are possible in applying the interpretation method (simple code, full code) and interpretation place (client side, server side). That is, various combinations are possible in the application of the analysis method (simple code, full code) and the interpretation place (client side, server side).

The advantage of applying the short input method and the full input method in parallel is as follows. First, since the full input method can be used, the user can input all the words even if they do not exist in the dictionary other than the predefined word, and the simple code for the use of the shortcut input method for the common phrase / Full association) can be specified, and by specifying a partial associative simple code, the number of input strokes can be greatly reduced. There is also an advantage in that word-based initials can be assigned to phrases as well as words. However, in the foreign method, since the method using the index of the word unit is used for inputting all the words, in order to minimize the case where the same code is given to different words, it is necessary to use the entire associated simple code.

In addition, the system must have an "index" that has code values for certain common phrases and their common phrases, requiring much less storage space than foreign methods that have an "index" for every word do. In order to eliminate ambiguity, this "index" should have an "index" for the correct word or an "index" for the correct word for the words that may cause ambiguity. In order to eliminate this ambiguity, .

In all languages, the phonetic value of a particular word is a consonant, so techniques for extracting consonants and making an acronym have already been widely used. In the case of English, for example, consonant "CPT" with a phonetic value in "captain" is extracted and used as an abbreviation, "PVT" is used as abbreviation in "private", "SGT" , "SSG" as an abbreviation in "staff sergent", SFC as an abbreviation in "sergent first class" and so on. Of course, the examples "captain" and "private" are two syllables each, but the consonants extracted by abbreviations can be seen as consonants representing each syllable. Therefore, in case of "captain", "278" associated with "CPT" can be designated as simple code.

In this way, the ability to apply the shortened input method by designating the partial associative simple code for the commercial word arbitrarily based on the syllable is significant in addition to the reduction of the input effort. Phonetically, syllables are defined as "psychological reality." In addition, the consonant has a phonetic value in the syllable. It is almost impossible to deduce the captain when extracting only the vowel "AAI" from the example captain. However, if you extract the consonant "CPTN" or "CPT", you can easily approximate the captain. It is possible to deduce the original sentence in the usual case even if only the consonant is removed by removing the vowel by each word in a certain sentence of English. That is, the use of the partial associative simple code in association with each consonant constituting the syllable implies that the user can naturally adapt to the short-axis input method, and it is convenient for the user.

Especially in the English-speaking countries, it is general to use abbreviations. In the case of a listed company name, a certain number of abbreviations are specified. Therefore, simple codes can be used based on this abbreviation.

Allowing the user to specify simple codes (partial associations, full associations) for a particular phrase has the advantage of making it easier to remember the code values for common phrases. Furthermore, if a user needs only a very small number of nomenclature (for example, only 10 or fewer nominal words), he or she will not be given the code associated with the alphabet of the common phrase, , 2, 3, ..., and so on.

6.8 Grouping of Simple Code / Corresponding Phrases and Designation of Search Scope

If a simple code is assigned to a plurality of phrases, there is a possibility that many redundancies may occur. Grouping of the phrases corresponding to the simple code to search for a simple code only for a specific phrase group causes ambiguity between the simple codes (second ambiguity) Can be reduced. A phrase does not necessarily have to belong to only one group, but it may belong to several groups.

For example, simple naming phrases are grouped into a group of listed company names, city names, commercial phrases, ..., and again, the commercial phrase groups are grouped into sub-groups such as social fields, political fields, Grouping. In this example, a two-level tree-type grouping is proposed, but tree-type grouping is possible in three, four, or more stages. When the user (or system) restricts the search range of the simple code to the company name group, when the specific simple code is input, the system searches for the named word corresponding to the simple code inputted only in the category of the listed company name group, Ambiguity can be reduced. Similarly, if the search range is a common phrase, all the subgroups below the common phrase group can be included in the search range. If the social field group of the common phrase group is designated as the search range, only the group of the sub-category including the social field (in the tree-shaped group structure) will be the search range.

6.9 Using Relay Server

The interpretation of the simple code can be done either on the client side or on the server side, and dedicated to the decoding of the simple code (including the full code in some cases), providing the word corresponding to the simple code to the client side or other server side A relay server can be placed. See Fig. 6-1. Also, in FIG. 6-1, if the client decodes the simple code primarily and does not interpret the phrase corresponding to the input simple code, the phrase corresponding to the simple code input from the relay server is interpreted as secondarily, , It is possible to interpret the phrases corresponding to the simple codes input from the respective servers again in the third place. The tertiary simple code decryption server (referred to as "tertiary server" for convenience) is a server equipped with an application that uses a simple code corresponding to the inputted simple code or a simple code.

Even if the third server side requires a phrase other than the simple code, if the user inputs a simple code and the third server side does not store a phrase corresponding to the simple code and the simple code, The server interprets the simple code inputted from the user and the phrase corresponding to the simple code can be transmitted to the third server side.

Each time a code value of a simple code is input, the index corresponding to the simple code can be retrieved and feedback can be given to the client side or each server side or feedback can be given word by word.

6.10 Division by word

In the present invention, word unit means from the beginning of a word to the end of a word. This can be identified through a combination of all elements (word start, space, mode change, enter, ...) that can distinguish words from words. For example, from blank to blank, from blank to mode, etc., it is possible to identify that a word has been entered through word start to word end. Giving feedback on a word-by-word basis can be fully implemented in languages that currently support the network environment.

6.11 Downloading simple code / correspondence phrase

Further, even if the user does not directly input and store the simple code corresponding to the simple code and the simple code on the server side, it is possible to download the same to the client side.

Downloaded units can be downloaded as a single unit of phrase, or they can be downloaded as a group unit (group of tree structure) of the above phrase. When you select a higher group, you can download the lower group. The server-side phrase group tree structure can be downloaded while maintaining the tree structure of the server-side phrase group, and phrases belonging to the group and the lower group can be downloaded as a group designated by the user on the client side. If there is a relay server whose main function is decryption of the simple code, the relay server may be responsible for this function.

7. Enter symbols

It was explained in the previous application that the native language alphabet can be arranged in the order of "close to the reference grid", and then the numbers and the English alphabet can be arranged. In applying the standard iteration selection method, Alphabet, and number can be selected. Similarly, in applying the subsequent control processing method, not only the native language alphabet belonging to a specific button, but also numbers and English alphabets can be inputted through the following control processing method.

The present invention proposes a method (that is, a method of concealed control processing) that enables inputting without being displayed on the keypad, which is one step further, which can be displayed on the keypad and inputted on the keypad do.

In other words, one of the grids in which the controls are placed in the prior art is to input symbols by placing a "symbol control" on a suitable grid, and combining the symbol control and a button (other than a control button) Here, for example, a button that can mean a symbol is a [5] button because a dot can easily represent "ㅁ" in a period.

For example, in the embodiment of the Korean patent application (Fig. 4-2), the symbol control can be placed at the position of the grid where the [*] button can be selected by two successive presses. That is, the relationship between the representative alphabet and the subsequent alphabet, such as a (representative alphabet), k (2nd), symbol (3rd), ... In case of control line input, when you enter "period", ㅁ = {symbol} + ㅁ = [*] + [*] + [5]. When inputting after control, ㅁ = ㅁ + {symbol} = [5] + [*] + [*]. If you place the symbol control at the position of the grid that can be selected by pressing the [*] button three times, the input of the [*] button is added one by one in the example.

If you have only one symbol control, you can enter only about ten symbols, even if you give one symbol for each of the ten number buttons. An example of giving the meaning of a symbol to each button is as follows.

[1] Button:? (Meaning that "a" is placed and similar to "?")

[2] Button:! Meaning ("ㄴ" is placed, the first letter of "exclamation point" is the same)

[3] Button: Meaning of $ ("ㄷ" is placed, the first letter of "dollar" is the same)

[4] Button: ...

[5] Button:. Meaning ("ㅁ" is placed in the "punctuation" is the same as the first letter)

[6] Button: Meaning of * ("ㅂ" is placed in the first letter of "asterisk" is the same)

[7] Button: Meaning of, ("ㅅ" is placed, the first letter of "comma" is the same)

[8] Button: Meaning ("ㅇ" is placed, the first letter of "quotation marks" is the same)

[9] Button: Meaning of ~ (the vowel "ㅡ" is arranged, similar in shape to ~)

[0] button: The meaning of @ (the number 0 is placed and resembles the shape of @)

As mentioned above, symbols can be input by combining a button and a symbol control that can remind various kinds of symbols. The meaning of the symbol is given to each button. As in the example, the relationship between the name / shape of the symbol and the arranged alphabet, the relationship between the English name / shape and the arranged English alphabet, The meaning of the symbol can be given in consideration of the relationship of the symbols. This may not be the same as above because it may be different according to the individual's taste, and it may be possible for each individual to set (re) the meaning of the symbol for each button.

As a result, the frequently used symbols can be treated as if they were subsequent alphabets belonging to the easy-to-understand number buttons. In the above example, the question mark is associated with the [1] button where "a" is placed in consideration of similarity of shapes, because the period that is more frequently used than the question mark starts with "ㅁ".

Likewise, in assigning the meaning of symbols to each button, it is also possible to use an English name / shape or a numerical name / shape. The following examples can be applied in combination with the case of the native language.

[1] Button:? (With the letter "q" in place: same as the first letter of "Question mark")

[2] Button: Meaning of, ("c" is placed, but the first letter of "Comma" is the same)

[3] Button:. Meaning ("d" is placed, the first letter of "Dot" is the same)

[4] Button:! Meaning ("i" is arranged and resembles shape with "!")

[5] Button: ...

[6] Button: ...

[7] Button: Meaning of / ("s" is placed and the first letter of "Slash" is the same)

[8] Button: Meaning: (number "8" is placed: similar to shape)

[9] Button:! (Pronounced "x" is associated with "eXclamation mark")

[0] button: The meaning of @ (the number 0 is placed and resembles the shape of @)

Giving meaning of symbols based on English can be useful in non - English language areas using keypads written in English. Also, setting the colon with the similarity of the shape of the number 8 has the advantage of being universally usable regardless of the language. Similarly, comma can also be regarded as a subsequent alphabet of the button [9], with similarity to the number 9, but not in the above example.

You can set the symbol control to the appropriate button. In English, if you do not place controls for other purposes in the [*] button in Figure 1-1, select the [*] button 1 Tarot Symbol Control (ie place the symbol control at the position of the [*] You may. In European languages where there are subscripted variants of the alphabet, you can place symbol controls at the position of the reference grid of the [0] button or [#] button. However, if you place symbol controls on the [0] button, it is better not to give the "@" sign as in the example above.

If you put the symbol control on the [*] button and apply the input after the control, in English, you can enter colon (:) in Figure 1-1: = [8] + {symbol} = [8] + [*] do.

As you can see in the example above, if you give each symbol a meaning associated with each button and place the symbol control on only one of the control buttons, only about 10 symbols can be entered. Also, in assigning meaning to each button, it is possible to assign a meaning of slash, semi-colon, period, etc. to a button assigned with "s" as in the example of English, but only the meaning of slash, which is one of them, is given. Since the dot assigned to the button to which "d" is assigned is also given as the dot, in the case of the exclamation mark, "!" is assigned to the button assigned "i" .

Thus, by allowing a number of symbol controls (for example, symbol control 1, symbol control 2, ...) to be selected, a greater number of symbols can be input through the control processing method. For example, "d" gives the meaning of the assigned dot (or "button" assigns the meaning of the "dot" to the assigned button) have.

If you want to select "Symbol Control 1" with the [*] button 3 as shown in the example of Figure 7-2 where the symbol control is added to Figure 4-5 and apply the input after control, dot = [3] + [3] + {symbol 2} = [3] + [*] + [*] + [*] + [ [*]. From the point of view of how to handle this chain of subsequent controls, comma = dot + {next} = dot + [*] = [3] + [*] + [*] + [*] + [*]. If you do not enter the tremor by the control processing method (that is, if you do not have a tremor control), it is natural that "Symbol Control 1" is selected for the [*] button 2 (skip control processing). Likewise, colon and semi-colon of similar shapes can be regarded as subsequent alphabets assigned to the same button and can be entered by control processing. Similar symbols can be applied to other symbols.

Even if two symbol controls are used with "Symbol Control 1" and "Symbol Control 2", it is necessary to give meaning to each symbol and remember it, and there is a limit to the number of symbols that can be input do. Therefore, by grouping symbols with the same techniques as dot and comma, and grouping colon and semi-colon, you can have more symbols by entering multiple symbol controls.

It is desirable to make the grouping of the symbols also convenient for the user. The present invention shows an example of symbol grouping that can be used generally. First, a variation of the dot can be set as a group based on the shape of various symbols. For example, dot (.), Comma (,), colon (:), quotation mark ("), ..., question mark (?), Exclamation mark (! It can be grouped as a dot, or a "zero-dimensional" symbol grouped into groups, where? And! Are both 0-dimensional and 1-dimensional, In order to determine the ranking of the affiliation of the group, it is preferable to be able to set the user to set the rank of the group, although the frequency of use and the like can be considered as mentioned in the earlier application. When the number of symbols is large, it is convenient to input the symbol control afterwards, and in the terminal with the display window, the symbol changes according to the depression of the control button.

It is also possible to associate the grouped dot type (0-dimensional type) symbol with a specific button so that it can be set at the convenience of the user. For example, if you can represent a group and the most frequently used symbol is a dot, you can think of it as a subsequent alphabet belonging to the button [3] containing the dot "d". In the example of Fig. 7-1 where symbol control is added in Fig. 1-1, when the symbol control button is the [*] button and the input is applied after the control, dot = [3] + [ *, * [+] + [*], colon = [3] + [*] + [*] + [*], semi-colon = , .... Or if you think of it as the next alphabet belonging to the [0] button, it will be combined with the [0] button, not the [3] button. Otherwise, the dot form is the most basic form and can be considered as a subsequent alphabet of the [1] button.

Next, you can group the symbols in a line, or "one-dimensional" form, into groups. For example, you can use slash (/), hat symbol (?), Question mark (?), Exclamation mark (!), Round parenthesis 1 ((), round parenthesis 2 () Grouping such as 2 (>), right angle bracket 1 ([), right angle bracket 2 (]), tilde (~), minus (-), arrow 1 (<-), arrow 2 can do. As described in the prior application, an accessory rank may be set in consideration of the frequency of use and the like, and associating it with a subsequent alphabet of a specific button may set an appropriate button as described above. For example, as a subsequent alphabet of the [1] button, or as a subsequent alphabet of the [5] button on which the alphabet "l" is placed.

Then, the combination of lines, that is, symbols of the "two-dimensional" form, can be grouped into groups. For example, at (@), ampersent (&), asterisk (*), sharp (#), dollar ($), yen sign (W + =), yen sign (...) ,), ☏, ☏, 검은, ☏, ☏, ☏, ☏, ☏, ☏, ☏, ☎, ☜, ♨ and so on. Also, the ranking of the accessories can be made in consideration of the frequency of use, and an appropriate method of associating with a specific button is selected. You can associate a zero-dimensional symbol or a one-dimensional symbol with a button other than the one associated with the button.

As mentioned above, when grouping symbols into three groups of zero-dimensional one-dimensional and two-dimensional shapes (this is called "three large groups" for convenience), it is advantageous to store only three related number buttons. However, When inputting, there is a disadvantage of pressing the control button several times. Therefore, if you see an example of subdividing a few groups (called "subgroups" for convenience):

First, a symbol group (eg, *, #,%, ...) that forms a combination of lines in a two-dimensional symbol group is divided into a symbol group (eg, ◁, ◀, ...) . In addition, groups of symbols such as ☏, ☎, ☜, ♨, ... in the group can be placed in separate groups. You can also place it in the following alphabet that belongs to the appropriate button. If you leave these groups separately, you can exclude or exclude these symbols from the preceding symbol group, which is the same for all other cases.

Next, the symbols used in the mathematical expressions of the one- or two-dimensional symbols, ie, +, -, *, root (√), sigma (Σ), integral (∫) Group. You can also place it in the following alphabet that belongs to the appropriate button.

You can also divide the symbols that can represent the direction: →, ←, ↑, ↓, ↗, ↙, ↖, ↘, ◁, ▷, ◀, .... You can also consider the subsequent alphabet in relation to the appropriate button.

And, it is also possible to group various brackets, (,), [,], {,}, <,>, ..., which can form another group relatively feasibly. Also, when grouping in parentheses, the left parenthesis and the right parenthesis can be grouped separately.

In the case of allowing the subgroups to enter symbols without entering the group of 3 major groups, it is possible that the alphabet belonging to the subgroup can be left in the three major groups or not. In the case of the three major groups, .

The above symbol grouping is applied to FIG. 1-1, and an example in which each symbol group is regarded as a subsequent alphabet of a specific button is as follows. The symbol group of the 0-dimensional form is regarded as a subsequent alphabet belonging to the button [0], the symbol group of the one-dimensional form is regarded as a subsequent alphabet belonging to the button [1], the symbol group of the two- Considering a symbol group in the form of a single closed curve among the symbol groups in the two-dimensional form, considered as an alphabet, is regarded as a subsequent alphabet belonging to the button [8], and a group of pictorial symbols in the two- , The mathematical symbol group is regarded as a subsequent alphabet belonging to the button [6], the directional symbol group is regarded as a subsequent alphabet belonging to the [3] button, the group of parenthesis symbols are assigned to the next alphabet belonging to any button among the remaining number buttons Can be considered. As described above, in associating a symbol group with each button, this is only an example, and can be set according to the convenience of the user.

In conclusion, the symbols can be grouped into three groups (0-dimensional, 1-dimensional, 2-dimensional) in the control processing by considering them as the following alphabet belonging to a certain button, or by subdividing them into 10 or less groups It is one of the core of the present invention that it has been shown that almost all symbols can be inputted by grouping. Also, in considering each group of symbols as a subsequent alphabet belonging to a particular button, the symbols are regarded as a subsequent alphabet belonging to a button associated with a group of symbols of name, dimension, shape, etc. so that symbols are not displayed on the keypad, It is one of the core of the present invention that the "concealed type subsequent control processing method" can be used while maintaining the alphabet arrangement.

The control buttons for symbols in this application mainly use the [*] button or any of the up and down buttons, but you can use the [#] button as a follow-up control button for numbers and English alphabet. For example, if the [#] button is already being used as a subsequent control button, you can add additional controls for numbers and English alphabets to the available grid on the [#] button. Again, in the choice of controls, as mentioned earlier, you can skip controls that can not be combined with the alphabet of the representative, so that the next available control is selected.

8. How to use the Move button

8.1 Using the Move Button as a Control Button

In the prior art, a control button in which various controls are arranged may be placed on any button in the 4 * 3 keypad or in a separate button other than the 4 * 3 keypad. And for the languages that have a large number of alphabets and many variants of alphabets in the first sentence, you may have experienced a lack of buttons to use as control buttons in the 4 * 3 keypad. In the present invention, it is pointed out that the primary function of the left / up / down movement buttons which are not used relatively frequently in the character input mode can be utilized as the control buttons mentioned in the present invention. In other words, when using a separate button outside the 4 * 3 keypad as a control button in the character input mode, the up / down / left button is used as a control button.

FIG. 8-1 shows a button of a folder type terminal which is typically used at present. The [i] button indicated by a dashed line is a button for accessing the Internet, and this button may or may not exist depending on the terminal. Here, the right movement button is used for blank input, and in Korean, it is also used as a syllable (letter) confirmation button for eliminating the first ambiguity. In the menu selection mode other than the character input mode, the up / down / left movement buttons are usefully used as a movement button for selecting a menu. However, in the character input mode, the up / down / left movement buttons are not frequently used, and in particular, the up / down movement buttons are not frequently used. For convenience, the up / down / left movement buttons are collectively called "up / down movement buttons" or "up / down buttons ", and the up / down movement buttons are called" The same applies to the case where only one movement button is referred to.

8.2 Movement Button Bottom Layout

First, the up and down buttons are usually placed on the numeric buttons. However, in order to utilize the primary function as a button for various alphabet input in the character input mode, it is useful to be placed at the bottom of the 4 * 3 keypad together with the [*] and [#] buttons used mainly as control buttons . Figures 8-2 and 8-3 illustrate this. However, this is not necessarily so, and for convenience, the example of the present invention will be described as an example in which the movement button is disposed at the lower side of the 4 * 3 keypad.

It can be seen that a 5 * 3 keypad can be constructed by combining the 4 * 3 keypad and the up and down buttons. This means that when applying the partial selection method, each button can be divided into 15 groups of 3x5. Similarly, it is not necessary to arrange the upper and lower left and right buttons so that the 5 * 3 keypad can be configured as shown in FIG. 8-3.

8.3 Move button Left or right side layout

The up, down, left, and right movement buttons can be placed on the left or right of the 4 * 3 keypad.

In this case, the 4 * 3 keypad and the move button can be combined to form a 4 * 4 keypad. FIG. 8-4 shows an example in which the up, down, left, and right movement buttons are provided on the right side of the 4 * 3 keypad.

This is an advantage that the size of the liquid crystal of the terminal is getting bigger, and the size of the liquid crystal of the terminal can be made larger. In addition, there is a good characteristic in the parallel application of the side battery mounting method in the mobile terminal proposed in the applicant's Korean Patent Application Nos. 10-2000-0002081, 10-2000-0005671, 10-2000-0067852, and 10-2001-0002137.

8.4 Examples of control buttons and buttons for alphabet input

Here is an example of using the move button. However, it is not limited to the example below.

8.4.1 Application example with symbol control button

In the Korean example, there were cases where the sound and sound control were placed on the [*] button and the [#] button, respectively. There were also cases where the [*] button was placed with a shaky controller and the shaky control, and the [#] button was placed with only the basic vowel control and the extended vowel control, and only the extension vowel control was placed with the [#] button. In this case, the symbol control is placed on the [*] button or the [#] button. After the control button is pressed, the humming, hyphenation, etc. first appear first and then the symbol is selected. This is the same in other languages.

However, if the symbol control is separated and placed on any one of the up and down buttons, the symbol associated with the group of symbols and the symbol control button with the symbol control can be combined to input the symbol immediately. FIG. 8-5 shows an example in which the primary function of the downward movement button is used as a control button for selection of symbol control. [3] + [v], comma = [3] + [v] + [v], and colon = [3] + [v] + [v] + [v], semi-colon = [3] + [v] + [v] + [v] + [v]

8.4.2 Use as a collection element button in Korean

In particular, in the case of using the vowel element (ㅡ, ㅣ,.) In the example of Korean in the prior application, it was inconvenient to input the vowel element "ㅎ" by arranging the vowel element " This disadvantage can be overcome by disposing it on any of the left buttons. If you place the symbol control on the Down button and put the vowel element "." On the Up button, you will use the two buttons on the up and down buttons. Alternatively, three Korean vowel elements can be placed on the left and right buttons.

Just as you put a symbol control on a button that has a sham sound control, the Korean vowel element "." Is added to the reference grid position of any button in the left and right buttons. The symbol control may be placed in the order close to the reference grid. Figure 8-6 is an example of this. In this case, the vowel element "." Is not used singly, so even if the vowel element and the symbol control arranged by the iterative selection method are selected, the vowel element and the symbol control can be selected without ambiguity. In Figure 8-6, if you press the [v] button once, the vowel element "." Is selected, and if you press twice, the symbol control 1 is selected, and if you press it 3 times, the symbol control 2 is selected.

8.4.3 Example of using Japanese as subscript control button

In Japanese, the arrangement of the 50-note chart corresponds to each button, 2nd and 3rd follow-up controls are assigned to the [*] button, and 4th and 5th follow-up controls are assigned to the [#] , Control for long sound / mute sound / answer sound input can be put on any one of the up and down buttons. See Figure 8-7.

8.4.4 Examples of using as a subscript control button for entering a vowel in Arabic

In Arabic, controls for processing subscripted vowels can be distributed over any button (s) in the up and down buttons.

8.4.5 Examples of using Thai as a control button

In Thai, consonant control and vowel control are not separated, but one control button is used as a follow-up control button. Any one of the upper and lower buttons can be additionally used as a control button. Or other control buttons.

8.4.5 Example of application with short / full switching control button

There is a third ambiguity between the simple code and the full code when the parallel input method is applied. In order to eliminate the ambiguity, a word-based "short / full" conversion control method is proposed. For example, if you want to use the full input method as the basic mode and enter words by the shortcut input method when applying the parallel input method, first select the "short / full" conversion control, enter a blank . Of course, the order of the whitespace and "short / full" toggle controls may change. Here, word-based "short / full" toggle controls can be placed on any of the up and down buttons. Alternatively, you can place controls with the "Short / Full" toggle control and the blank (right button) together at the reference grid of any button in the up and down buttons. See Figure 8-8.

Assuming that the English alphabet shown in FIG. 1-1 is arranged in the numeric buttons of FIG. 8-8, the entire associated simple code "4357" of the help is inputted while the basic alphabet input mode is the full input mode, You can input "~ Full code input + [^] + [4] + [3] + [5] + [7] + [+] + Full code input ~". That is, since the movement function of the up-shift button [^] is limited and the word-based "short / full" switching function and the blank function are added together, the moment the [^] button is pressed, the system displays the next "[4] + ... "Is not a full code but a simple code, and referring to the index, it is possible to recommend a word closest to the input [4] to the user. As soon as the input of [4] + [3] + [5] + [7] is completed and the blank button ([>] button) is pressed, the word is terminated and the word "short / And again waiting for the full code to be entered. If the [^] button is pressed again after the input of the simple code 4357, the system recognizes that the word is also terminated, confirms the help corresponding to 4357, and waits for input of the simple code again.

In the parallel input method, if only one right button (blank button) is used, there may be a third ambiguity between the full code and the simple code as mentioned in the earlier application. In order to avoid this, , Whether a simple code exists or whether it is a promised full code. However, by putting the "short / full" mode switching of the word unit and the blank button together, the system can recognize the input value as a full code or a simple code, so that it is possible to improve the performance of the system will be.

8.5 Examples of using the add / drop button in calculator mode

The four movement buttons can be usefully used as the add / drop (+, -, x, /) buttons that are most frequently used in the calculator mode regardless of their position. You can mark the button for the add / drop system on the button, but it will not be used frequently because it will not be used more often than the alphabet input. In the alphabet input mode, each button will be used as a move button or a control button.

(√3)은 3//2 로 풀어 제(/)버튼을 반복하여 누름으로써 "제곱근"연산자를 선택하도록 할 수 있다. 이외의 이항연산자는 중복하여 출현하지 않으므로 적절한 가감승제버튼에 속한 후속연산자로 두고 후속연산자를 반복선택방법에 의하여 선택하도록 할 수 있다.In addition, it is possible to select an operator that can be used in the calculator by a (selection type) repetition selection method by placing it on the acceleration / deceleration button. Operators (binary operators) often used in calculator mode are based on properties that do not appear repeatedly. For example, there can be no calculation of 2 ++ 1. Also, 2 ⁴ can be solved with 2xx4 and the "squared" operator can be selected by repeatedly pressing the w (x) button. That is, it is the same as repeating selection with a multiplier (xx) operator as a succeeding operator on a w (x) button. Likewise

(√3) can be set to 3 // 2 and the "square root" operator can be selected by repeatedly pressing the (/) button. Since other binary operators do not appear redundantly, it is possible to select a subsequent operator as a subsequent operator belonging to the appropriate acceleration / deceleration button and select a subsequent operator by the iterative selection method.

You can also use the [*] button with the additive (+, -, /) operator on the three buttons of the up, down, left, and right buttons and the w (x) operator.

9. Activate help feature

Here, functions not displayed on the buttons (up / down / left / right) in each input mode can be displayed on the screen (liquid crystal display), so that convenience of use can be added. In this case, there is a disadvantage in consuming a part of the liquid crystal. Of course, a user who functions as a button of each operator does not have to display the liquid crystal space while consuming space. 8-1. FIG. 9-1 is an example of a case where the upper, lower, left, and right buttons are arranged on the right side of the 4 * 3 keypad and arranged in a similar manner as shown in FIG.

This is referred to as "activation of the help function" for the convenience of the user to display the function of the button (that is, the operator assigned to the button or the group of symbols associated with each button). Activation of the help function can be done for each mode (eg alphabet input mode, calculator mode), for the required function in each mode (eg the use of numeric buttons or control buttons associated with symbol groups in alphabet input mode) It is possible.

Likewise, the numeric buttons associated with the function or symbol group of the control button presented in the prior application can also be displayed on the liquid crystal display if required by the user, thereby facilitating the convenience of the user. See Figure 9-2. 9-2 is an example in which the number buttons associated with the respective symbol groups are displayed as icons on the liquid crystal display in accordance with the symbol group classification illustrated above. Of the symbols in the symbol group associated with each number button, only the first selected symbol is added to the numeric button icon for convenience.

10. How to use the Delete button

In utilizing the delete button, it can be utilized as "final input cancel" introduced in the prior application. For example, to input "a" in Fig. 4-5, enter "1" + [*] to input "ㅋ" and press the delete button to cancel the final input ([*] It can be done. This can be useful if you want to repeatedly press the control button to enter a subsequent alphabet. When the cancel button is pressed successively, it is sufficient to delete an already known alphabet by a usual method. For example, if you press the cancel button once while typing "Ghana", it will be "Ghana", once again, it will become "Ghana" and once again, it will become "Ghana". In the case of the roman alphabet, "aba .." is entered (last letter "a .." is a variant alphabet consisting of ".. + a" , And once again, it becomes "a". That is, the already formed alphabet is deleted in alphabetical units.

11. Unification of the numeric keypad of the keyboard and the keypad of the telephone terminal

It is obvious that the prior art and the keypad according to the present invention can be applied to all fields such as a numeric keypad of a mobile terminal or a standard keyboard, or a keypad or a door lock which is configured in software on a screen. Also, it is obvious that the numeric keypad provided on the standard keyboard differs from the prior art and the arrangement of the keypad and the numeric buttons according to the present invention. However, it is obvious that the prior art and the arrangement of the keypad buttons in the present invention can be applied to the keypad provided in the keyboard. For example, in the prior art and in the present invention, the alphabet placed on the [1] button is arranged on the [1] button of the numeric keypad provided on the keyboard, and arranged in the same manner as described below to utilize the alphabet input, simple code, Can be used for.

However, in order to reduce confusion and add convenience to use, the numeric arrangement of the telephone keypad can be utilized in configuring the numeric keypad of the keyboard. [4], [5], and [5] are assigned to the buttons on the second row and the second row on the numeric keypad on the keyboard, , [6] and [7], [8], [9] buttons on the third row. You can also use the [*] and [#] buttons as on the phone keypad.
