KR20010020973A - Alphabet input device and method in small keypad - Google Patents

Abstract

PURPOSE: A method for inputting alphabets in a small-sized keypad is provided to input all alphabets and numbers in the single keypad without mode conversion, and to make a user select an inputting method. The method is provided to utilize reference lattices and peripheral lattices based on the reference lattices according to usage frequencies of alphabets, to be applied to various kinds of languages. Therefore, inputting efficiency is maximized in the keypad. CONSTITUTION: The surface of each button is divided into many lattices corresponding to arrangements of entire buttons on a keypad. Lattices corresponding to locations of each button are determined as reference lattices. Alphabets or controls corresponding to each lattice are arranged. Alphabets or controls selected by sensing the first button and the second button are inputted. If the first button where the inputted alphabets or the controls are located is pressed, the pressing is read. If a button of the keypad corresponding to a lattice, where the inputted alphabets or the controls are located, is pressed, the pressing is read.

Description

Alphabet input device and its method in a small keypad {.}

[Technology Field]

TECHNICAL FIELD The present invention relates to an alphabet input device and 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 keypad.

Background

With the development of mobile communication, a function of transmitting and receiving digital information such as text has been added to a voice call-oriented portable terminal. Therefore, initially, a keypad provided in a portable terminal for the purpose of inputting a telephone number also includes a means for inputting a character. However, since the size of the keypad used as an input means of the portable terminal becomes smaller, the number of buttons included in the keypad has its limit. On the other hand, the letters consist of 27 letters for Korean, 24 letters for English, 50 letters for Japanese, and 24 letters for other Roman characters. Far outperformed. Therefore, in order to input one alphabet by using the telephone keypad, one or two or more buttons on the keypad must be combined to represent the alphabet.

Existing methods for entering alphabets on a small keypad can be roughly divided into alphabet selection type, alphabet generation type, and compromise type. The alphabet select type assigns a plurality of alphabets to each button on the keypad and inputs the alphabets assigned to each button according to the number of times each button is pressed.In the case of English, ITU-T (International Telecommunications Union-Telecommunication Standardization) Sector) proposed by Recommendation E.161. The alphabet generation type is assigned to the shape formed by assigning the letter size (eg →, ↓, ↙, ↘, ↘, ⊃, 0, etc.) to the button and pressing the corresponding basic buttons to form the shape of the alphabet to be input. The corresponding alphabet is inputted. In the compromise type, some alphabets are alphabetically selected, and others are alphabetically generated. According to the compromise method, Hangeul alphabets are input-processed with alphabet selection, and vowel alphabets are input-processed with alphabet generation using Cheonjiin 3 ashes.

As such, all three methods for entering an alphabet on the small keypad are represented by a combination of one or more buttons on the keypad for a specific alphabet.

The alphabet-selective method according to the prior art can be further classified into the following. The first method is to arrange a plurality of alphabets (usually 3 to 4 alphabets) on each button on the keypad, and press the button once so that the first alphabet and the second alphabet are inputted. The second method is to place a number of alphabets (usually three to four alphabets) on each button on the keypad, press the button once to process the first alphabet, and press a specific button (for example, [#] or If you press [*]) and the button in combination, the second alphabet is inputted. The third method is to arrange alphabets between the buttons on the keypad and to press the corresponding buttons in combination so that the corresponding alphabets are processed.

The first method has the following disadvantages. Assume that three alphabets of 'A', 'B' and 'C' are assigned on the [2] button corresponding to the number 2. When the user wants to input 'A', 'B', and 'C' consecutively by the first method, the user should press the [2] button six times in succession. In this case, the user's behavior is input of 'A', 'B', 'C', 'B', 'B', 'B', 'C', 'B', 'A' It is hard to tell whether you typed in. In order to classify this, the user must input [2] button by time delay like [2]-[2] [2]-[2] [2] [2]. However, when inputting by a keypad of a terminal (for example, a general telephone) without a display window, it is difficult to check whether the user inputs the input correctly as intended. Further, according to the first method, the larger the number of alphabets to be placed on the keypad, the greater the number of buttons to be pressed to enter one alphabet. In other words, if three alphabets are placed on one button like English, an average of two key presses is required per alphabet. If five alphabets are placed on one button like Japanese, one alphabet is required. On average, three button presses are required. Therefore, when five or more alphabets are assigned to one alphabet, such as Japanese, it is sometimes necessary to press the same button five or more times in order to input one alphabet, which makes the character input inconvenient and the accuracy thereof very poor. do.

In the second method, if you want to enter alphabets that are not first assigned to each button on the keypad, you must press a specific key (for example # or *) on the keypad in combination with the button on which the alphabet is placed, thus giving the user an alphabet. Difficult to know how to input

The third method has the advantage that the input process is simple and consistent. However, it is not easy to use keys for memorizing phone numbers, and as the terminals of cellular phones and the like (cellular, PCS, IMT-2000 terminals, etc.) are miniaturized, the space between buttons on the keypad becomes smaller and smaller. There is a disadvantage that it is difficult to write the alphabet of.

Hereinafter, with reference to the accompanying drawings will be described in detail the present invention.

In the present invention, the keypad is based on the keypad used in the general telephone. Therefore, the keypad used in the present invention is [1], [2], [3], [4], [5], [6], [7], [8], [9], [0], [ Assume that 12 buttons of #] and [*] are provided. At this time, the keypad consisting of nine numeric buttons of [1] to [9] is called “3 * 3 keypad”, and the ten numeric buttons of [1] to [0] and the [*] and [#] buttons. A keypad consisting of twelve buttons, including the "3 * 4 keypad" is called.

First, the "partial whole selection method" according to the present invention will be described.

According to the " partial full selection method " according to the present invention, when each button on the keypad is configured to form a predetermined number of grids in a form corresponding to the arrangement of all the buttons in the keypad, alphabets are arranged on the grids, and a certain alphabet is to be input. By pressing a combination of the first button on which the alphabet is arranged and the second button on the keypad corresponding to the arrangement position of the alphabet on the grids of the first button, the desired alphabet is input.

This "partial whole selection method" is based on the principle that the microcosm (arrangement of the alphabet on the buttons) reflects the grand universe (arrangement of the buttons on the keypad). That is, self (microcosm, button) is created from this world (major universe, keypad), self (microcosm, button) reflects this world (major universe, keypad), and self (button) exists and this world (keypad) According to the principle of the presence of), buttons for entering each alphabet are combined. This method is therefore sometimes referred to as the "partial whole selection method" or the "microcosm selection method."

"Partial whole selection method" has the advantage that the input method is very simple and there is no ambiguity in the input, while it is necessary to press the button twice for one alphabet input. There is a disadvantage that it can be relatively large compared to the iterative selection method.

In applying the "all partial selection method" according to the present invention, when the user combines the first button and the second button on the keypad, the order according to the convenience of the button combination is as follows.

The convenience of the button combination may vary slightly depending on the character writing method of each country (for example, horizontal writing and vertical writing) and personal taste, but is based on an ordinary person who is familiar with horizontal writing.

In determining the order according to the convenience of button combination, the factors considered in the order of equal combination, left and right combination, straight combination, and adjacent combination are shown in Table 1.1.

In determining the order according to the convenience of button combination, the factors considered in the order of equal combination, left and right combination, adjacent combination, and straight combination are shown in Table 1.2.

In determining the order according to the convenience of button combination, the factors considered in order of equal combination, adjacent combination, left and right combination, and straight combination are shown in Table 1.3. Considering adjacent combinations first, space can be efficiently used when using some grids on buttons.

For those who are familiar with vertical writing, in the order of convenient input, the factors considered in this table are "Equal Combination-Adjacent Combination-Vertical Combination-Straight Combination", as shown in Table 14.

Tables 1.1, 1.2, 1.3 and 1.4 are used to assign more frequently used alphabets to more convenient combinations, respectively, in placing alphabets on each button on the keypad.

In Table 1.1, the combinations of steps 1 to 10 all use nine numeric buttons such as [1] to [9] on the keypad, so it is defined as "3 * 3 button combination", and the entire combination of steps 1 to 12 is defined as " 3 * 4 button combination ". As described above, to distinguish the combinations in terms of the number of buttons used, the number buttons such as [1] to [9] or [1] to [0] are mainly used for alphabet input, and the function buttons are used instead of the alphabet input. This is because you can use [#] and [*].

For example, the number of 3 * 3 button combinations of left and right linear combinations (ie, 3 * 3 left and right linear combinations) is 27 (= 3 * 9), which is sufficient to represent an English alphabet. In addition, since the number of linear combinations (ie, 3 * 3 linear combinations) of 3 * 3 button combinations can express 45 (= 5 * 9) kinds of alphabets, 3 * 3 linear combinations of most languages Can represent alphabets Accordingly, the present invention can be effectively applied to languages having a large number of alphabets such as Japanese, Thai, Myanmar, Hindi, and Cambodian. Table 2 shows the number of cases according to each combination.

1 illustrates an example in which each button on the keypad is divided into grids corresponding to the arrangement of the buttons on the keypad.

The positions of the alphabets for the same combination are the grids shown in black in FIG. The grids of positions corresponding to the same combination are called "reference grids", respectively. The grids of positions corresponding to the left and right linear combinations are shown in dark gray in FIG. 1, and are referred to as "reference rows" because they are rows including reference grids. In FIG. 1, the grids of the columns including the reference grids are referred to as "reference columns" because they are displayed in light gray. In addition, the grid consisting of three rows and one row corresponding to the left and right linear combination including the reference grid in each button is referred to as a "3x1 grid", and the grid consisting of three columns and two rows including the reference grid is referred to as a "3x2 grid". The lattice consisting of two columns and two rows including the reference lattice is called "2x2 lattice", and the lattice consisting of three columns and three rows including the reference lattice is called "3x3 lattice".

If the number of alphabets is not large, the alphabets corresponding to some grids may be arranged according to the "convenience order of button combination" shown in Table 1.1, Table 1.2, Table 1.3, and Table 1.4. FIG. 2 illustrates an arrangement of gratings corresponding to each button applied when the number of alphabets is not large.

Rather than dividing each button of the keypad into a plurality of grids, the letters to be placed on the standard grid among the letters displayed on each button are displayed differently than the other letters in letter size, thickness, color, irregularities, or around the letters. Emphasis such as placing a border may indicate that the alphabet is to be placed on the reference grid. The alphabet displayed in this way is referred to as "reference alphabet" and is used in the same meaning as the alphabet arranged on the reference grid. In addition, the displayed keypad to which the concept of the reference lattice and the reference alphabet is applied is referred to as "reference keypad", and the keypad not otherwise referred to as "simple keypad".

The present invention uses a combination of two buttons on a keypad to represent a single alphabet. In a terminal having a display, after selecting a first button corresponding to one alphabet, candidate buttons for the second selectable button are displayed on the display. By displaying, the user can easily make a selection. In the case of Korean input, in the case of vowel input, it is possible to process 3 constellations by assigning them to 3 numeric buttons and to process consonants by assigning consonants to the remaining 7 numeric buttons using the principles of the present invention. have.

The partial partial selection method can accommodate multiple alphabets or controls using a grid on the keypad. Various function keys (control) such as mode change, move function, delete, and enter on the keyboard can be made by placing them on the grid of buttons such as [*], [0], and [#]. have.

Next, the "standard repeat selection method" according to the present invention will be described.

The reference repetition selection method is a method for selecting one alphabet among the letters arranged in the grids on the button in the order close to the reference grid on the button according to the number of times the button is repeatedly pressed on the reference keypad. In this case, the order close to the reference lattice does not mean a position physically close to the reference lattice, but is very similar to the order of high convenience illustrated in Tables 1.1, 1.2, and 1.3. The order of closeness to the reference grid may vary slightly depending on the characteristics of each language and the individual's disposition in that specific section. The standard repetition selection method has a merit that the number of button presses is relatively small by arranging alphabets frequently used in the reference keypad in a sequence close to the reference grid in a language having about 30 alphabets. The disadvantage is that ambiguity can occur.

Ambiguity generated in the reference repetition selection method may be avoided by the time delay between the input alphabets. At this time, since the degree of mastery of the button press of the individual may be different, the degree of time delay may vary for each individual. Therefore, it is desirable to be able to set a delay time suitable for the user himself in pressing a button by the reference repetition selection method.

There may be a method of setting the delay time as a relative time and an absolute time. The relative time is set as a ratio (for example, 120% or 80%) with respect to the reference delay time that is basically set in each terminal. The absolute time setting method is to set a desired delay time (for example, 0.5 seconds, 1 second, etc.) directly.

In the reference keypad, the most frequently used alphabet is arranged at the position of the reference lattice (that is, the position of the same combination). Therefore, according to the number of times the button is pressed, the alphabetical order of alphabets close to the position of the reference lattice, that is, the order of convenience of the button combinations illustrated in Tables 1.1, 1.2 and 1.3, should be identified.

When there are a large number of letters in the left and right or up and down positions (for example, the [5] button), the left and right alphabets may be selected first, or the upper and lower letters may be selected first. In addition, when there are a large number of letters in the position of the left and right linear combination (for example, the [2], [5], [8], and [0] buttons), the left alphabet may be selected first. It can also be selected first. This will depend on the culture and emotion of each country. Likewise, if there are multiple alphabets in the position of the up-and-down combination (for example, the [4], [5], [6] buttons), the upper alphabet may be selected first, and the lower alphabet may be selected first. It may be.

In the example below, the order in which the reference grid is close to the position of the reference grid is that the left and right gratings are closer to the upper and lower gratings in the reference grating, the left grating is closer than the right grating in the left and right directions, and the upper grating is lower than the lower grating in the up and down directions. Assume it is close. An example of applying these criteria is as follows.

For the [1], [3], [7], and [9] buttons, the following is an example of the order to be selected according to the number of button presses when the standard repetition selection rule is applied. This may vary slightly according to specific embodiments.

1st selection: Alphabet selection of reference grid position

2nd selection: Select the alphabet of the adjacent left and right linear combination position in the standard grid

3rd selection: Select the alphabet of the two spaces of the right and left combination

4th selection: Select alphabet of adjacent up and down linear combination position in the standard grid

Fifth choice: select the alphabet of two spaces

6th selection: select the alphabet of the diagonal combination

7th selection: Select the alphabet of the up / down combination position of three squares from the reference grid (for [1] and [3] buttons)

8th choice: select the alphabet of non-adjacent diagonal combination position in the reference grid

The following is an example of the order to be selected when the repetition selection rule is applied to the [4] and [6] buttons.

1st selection: Alphabet selection of reference grid position

2nd selection: Select the alphabet of the adjacent left and right combination position in the standard grid

3rd choice: select the alphabet of the two spaces

4th selection: select the alphabet of the upper left and right combination position on the standard grid

5th selection: Select the alphabet of the lower left and right combinations

6th selection: select the alphabet of the diagonal combination

The following is an example of the order selected when the iteration selection rule is applied to the [2] and [8] buttons.

1st selection: Alphabet selection of reference grid position

2nd selection: Select the alphabet of left and right linear combination position in the standard grid

3rd selection: Select the alphabet of the right and left combination

4th selection: Select alphabet of adjacent up and down linear combination position in the standard grid

Fifth choice: select the alphabet of two spaces

6th selection: select the alphabet of the diagonal combination

[5] The following is an example of the order to be selected when the repetition selection rule is applied to the button.

1st selection: Alphabet selection of reference grid position

2nd selection: Select the alphabet of left and right linear combination position in the standard grid

3rd selection: Select the alphabet of the right and left combination

4th selection: select the alphabet of the upper left and right combination position on the standard grid

5th selection: Select the alphabet of the lower left and right combinations

6th selection: Select alphabet of adjacent diagonal combination position in reference grid

7th selection: Alphabet selection of non-adjacent diagonal combination position in the reference grid

In the example of the [5] button, if there is no alphabet to be selected fifth, it is obvious that the alphabet described as fifth to sixth should be selected.

Hereinafter, in order to apply the "partial whole selection method" and "standard repeat selection method" according to the present invention, the alphabets corresponding to the letters of each country are represented, and examples of the reference keypad representing the function buttons for inputting the alphabets are presented. do.

If the reference keypad is configured for each language, there is an advantage in that the user can select the partial partial selection method and the standard repeat selection method according to the preference. In addition, the alphabet with a high frequency of use when the partial selection method is applied is arranged in a convenient position (grid), so that the convenience of input can be maximized, and the number of inputs can be minimized when the reference repetition selection method is applied on the same reference keypad. There is an advantage.

Not only alphabet input processing but also function buttons corresponding to various function keys of the keyboard can be processed in the same method. Examples of function buttons include function buttons for various mode switching (uppercase, lowercase, shift, character mode, numeric mode), moving function, enter, cancel input, subscript processing, and the like. This function as a function key on the keyboard is collectively called "control". The button on which the controls are placed is called a "control button" for convenience.

Normally the control is pre-populated to activate the function. However, the control buttons for subscript processing of the control can be seen as control buttons for alphabet input, and these controls can be pre-input or post-input to the alphabet to be combined.

These controls can be placed on the keypad buttons in the same way as the alphabet and can be applied to the partial partial selection method or the standard repeat selection method. The control buttons can be configured as separate buttons or via appropriate buttons within the 3 * 4 keypad. As described above, in many languages, the reference keypad is configured to process alphabet input using the [1] to [9] buttons (3 * 3 keypad) or the [1] to [0] buttons, and the remaining buttons ( It is possible to process control inputs using [*], [0], [#] or [*], [#]).

Furthermore, the alphabet input may be applied by using the partial partial selection method, the standard repetition selection method, or the simple repetition selection method, and the control input may be processed using the standard repetition selection method or the simple repetition selection method. However, if you want to use the control button repeatedly (that is, to apply the repeat selection method to control selection), the button on which the control is placed (that is, the control button) is used to select a different alphabet or different control on the reference keypad. Should not be used in the combination of choice. For example, if the alphabet is placed on the [1] to [9] buttons and the control is placed on the [*] button, the [*] button should not be used as a combination for alphabet input when the partial selection method is applied. The controls assigned to the *] buttons can be selected by the repeat selection method. Similarly, to apply the iterative selection method to the alphabet input and the partial full selection method to the control selection, the button with the alphabet placed as a combination for the control selection should not be used.

Regardless of the alphabet input method, using the control button repeatedly provides convenience of input when the number of controls assigned to the control button is not large. Using the control buttons for subscript processing (modified alphabet processing) helps to simplify the layout of the keypad, since it is possible to avoid placing all modified alphabets on the keypad. This is the same principle as typing A = [shift] + [a] when entering the uppercase 'A' in lowercase mode using a control called "shift" without placing both uppercase and lowercase letters in the alphabet. This is useful to process the modified alphabet on the keypad, in which the Roman alphabet includes English subscripts.

Furthermore, in languages with a large number of alphabets placed on the keypad, only a few alphabets (represented as "representative alphabets" for convenience) are displayed on the keypad and represent representative groups of alphabets that are frequently used and arranged on the buttons. When entering the alphabet attached to the alphabet (called "follow-up alphabet"), the subsequent alphabet can be entered by combining the control button (called "follow-up control button") and the representative alphabet. For reference, in the embodiment, when the entire display reference keypad is configured, the representative alphabet is usually used as the reference alphabet by arranging the reference grid.

In order to overcome the space constraints on the keypad, these controls are assigned to the following control buttons: controls 2nd, 3rd, 4th, 5th ... which are not found on the keyboard (representing the sequence attached to the representative alphabet, which is called "follow-up control" for convenience). And the subsequent alphabets are entered as a combination of representative alphabets and subsequent controls. These controls (2nd, 3rd, 4th, 5th ...-the sequence attached to the representative alphabet) can be selected by either the partial partial selection method or the standard repeat selection method. Similarly, if subsequent control buttons are not used in alphabetical or combinations for other control inputs, they may be used repeatedly (ie, repeat selection method) regardless of the alphabet input method. Likewise, subsequent controls can be pre-input or post-input.

When assigning the corresponding control button to the subscript control (modified alphabet control) and the subsequent control that can be used frequently, and applying the repeated selection method, the terminal with the display window does not necessarily display the control on the button. Can be further simplified. For example, if the [*] button is used as a subscript control button and the repeat selection method is applied, the terminal with the display window does not need to display the subscript according to the pressing order of the button on the subscript control button. The user only needs to know that the [*] button is a subscript button. Likewise, when using the [#] button as a follow-up control button and applying the repetition selection method, a terminal having a display window does not need to display a sub-alphabetic order on the follow-up control button. The user only needs to know that the [#] button is a subsequent control button.

Subsequent control buttons simplify the placement of the alphabet on the keypad. In particular, if the representative alphabet is arranged one per button, the simple repetition selection method and the number of inputs are the same, but there is no ambiguity. If there are a large number of subsequent alphabets, a number of subsequent control buttons can be placed (for example, [*] for 2nd, 3rd follow-up alphabets, [#] for 4th, 5th follow-up alphabets, etc.) to reduce the number of inputs while eliminating ambiguity. (See examples such as Japanese).

A reference keypad in which only the basic alphabet is placed by applying a subscript control (modifying alphabet control) without displaying the modified alphabet on the reference keypad is referred to as a "short reference keypad". A simple keypad in which only the basic alphabet is placed by applying a subscript control without displaying the modified alphabet on the simple keypad is referred to as a "simple simple keypad" for convenience. When both are spoken, it is called a "short keypad" for convenience. In addition, the keypad which simplified the reference keypad with only the representative alphabet by applying the concept of follow-up control without displaying the follow-up alphabet on the reference keypad is called "follow-up reference keypad" for convenience, and the keypad which applies the follow-up control to the simple keypad " Subsequent simple keypads. When referring to both, it is referred to as "following keypad" for convenience. The term "simplified keypad" is referred to collectively as both a simplified keypad and a subsequent keypad that apply the concept of a subscript control or a subsequent control.

When referring specifically to the reference keypad or the simple keypad displaying both the modified alphabet and the subsequent alphabet, it is referred to as " full display standard keypad " and " full display simple keypad " and collectively referred to as " full display pad ".

The method of processing the modified alphabet using the subscript control (modified alphabet control) on the simple keypad is called "subscript control method (or modified alphabet control processing method)" for convenience, and the method of processing the subsequent alphabet on the subsequent keypad for convenience " Follow-up control processing method. "

If the user remembers the alphabetical arrangement of the entire display pad (reference keypad or simple keypad) even on the simplified keypad (subsequent keypad or simple keypad), the input method (select all partial methods or select standard repetition) on the entire display standard keypad can be used. Method) or the input method (repetitive selection method) on the entire display simple keypad can input alphabets (modified alphabet or subsequent alphabet) not displayed on the simplified keypad. On the contrary, the entire display pad (reference keypad or simple keypad) can also be used to input subsequent or modified alphabets using the follow-up control method or the modified alphabet control (subscript control) method.

This means that the method proposed in the present invention can be complementarily applied to an entire display pad or a simplified keypad (simple keypad, subsequent keypad).

Considering the number of alphabets in each language, a method of constructing a reference keypad by arranging alphabets on a keypad is briefly described. In most countries, the number of alphabets is about 30. For example, 26 in English, 33 in Russian and 30 in Bulgarian. In the case of Korean, the number of alphabets is 14 consonants and 10 vowels, but the letters are composed of a combination of alphabets.

Languages with 30 or more alphabets can display alphabets and numbers using a 2x2 grid. Reference may be made to FIGS. 1-3.

There are also languages with nearly 50 alphabets. For example, 46 in Hindi, 46 in Japanese, 44 in Myanmar, and so on.

The above is the alphabetical structure in most languages. In the case of Thai and Cambodian, there are a particularly large number of alphabets. In the case of Thai, 76 consonants (44 are currently used) and 32 vowels have 76 alphabets. Actually, the alphabet used to input characters is 42 consonant alphabets and 20 vowel alphabet elements. The same is true for the Cambodian language.

In the alphabetical arrangement of languages having 27 or fewer alphabets, about 3 alphabetical letters can be arranged in the [1] to [9] buttons. Since about three alphabets are placed on each button, right and left combinations can be used. In this case, the partial full selection method can be applied even if the reference grid is not highlighted. This is because the user can know the reference alphabet intuitively when applying only the left / right linear combination or the up / down linear combination in the 3 * 3 keypad.

In the alphabet arrangement of languages having 28 to 30 alphabets, about three alphabets can be arranged in the [1] to [0] buttons. In case of using the right and left combination, the language is arranged by using 3x1 grid for each button. 3x2 grids can be used to arrange languages and numbers, and 3x3 grids can be used to arrange languages, numbers and English alphabets. See FIGS. 1-4. "A" means the native alphabet. In addition, the lattice is not used to arrange the numbers, that is, the numbers are arranged at positions other than the combination lattice, and the 3x2 lattice may be used to arrange the language and the English alphabet. See FIG. 1-5. In the alphabetical arrangement for each button, the same combination, right and left adjacent linear combination, and up and down adjacent linear combination can be used. In this case, the number can be placed at the position of the adjacent diagonal combination, which is to arrange the language alphabet and the number using a 2x2 grid. Including the English alphabet would use a 3x3 grid. See Figures 1-6.

For the alphabetical arrangement of languages with 30 to 33 alphabets, place three alphabets on the [1]-[0] buttons in the left and right combination, and three alphabets on the [*] or [#] button. Can be. In this case, the arrangement in the case of 30 or less alphabet letters can be similarly applied. However, in order to arrange all of the alphabets in the numeric buttons as much as possible, about 3 to 4 alphabets per button may be arranged at the positions of the left and right linear combinations and the up and down adjacent combinations in the [1] to [0] buttons. In this case, the 3x2 grid may be used to place the alphabet and numbers of the language, and only the alphabet of the language may be placed at the position of the left and right linear combinations. Including the English alphabet would use a 3x3 grid. See FIGS. 1-7 and 1-8.

In alphabetical arrangement of languages with 33 to 50 alphabets, about 5 letters of [1] ~ [0] buttons should be placed on each button, so the left, right, top, bottom, and adjacent diagonal combinations of each button Five alphabets can be placed at the position of. In this case, a 3x2 grid for each button can be used to place both the alphabet and the number of the corresponding language, and only the alphabet of the corresponding language can be placed at the position of the left-right linear combination. Including the English alphabet would use a 3x3 grid. It is also possible to place five letters in the position of the left and right linear combination. See FIGS. 1-9 and 1-10.

These guidelines are not hostile and may vary slightly depending on specific embodiments according to the characteristics of each language.

For most languages except Thai and Cambodian, the alphabet and numbers of each language can be displayed using a 3x2 grid. In this case, a 3x3 grid is used to display the English alphabet together on the keypad, unless the Roman language is used. 3 * 3 If the partial partial selection method can be applied within the keypad, the [*] and [#] buttons are used as control buttons, regardless of the alphabet input method (all partial selection method or standard repeat selection method). There is an advantage that the button can be used repeatedly (by applying the standard repetition selection method or the simple repetition selection method).

When using a 3x3 grid, it is not possible to use the full partial selection method within the 3 * 3 keypad to enable all combinations of national alphabets, numbers and English alphabets. This is possible through the layout of forms. In Fig. 2, a national language alphabet is placed in the grids (reference row) of the second row of the 3x3 grid of the buttons [4], [5], and [6] in the second row. The grids of the first row are arranged with numbers and national language alphabets. The grids in the third row are arranged with the English alphabet. It is apparent here that the arrangement of the grids of the first row and that of the grids of the third row can be interchanged. The configuration of the reference keypad in this form is referred to as "3 * 3 national language-number-English reference keypad" for convenience. See Figures 1-11.

Here, it is possible to give up the input of the English alphabet in combination in the 3 * 3 keypad and to input only the national language alphabet and numbers in the local language mode by the partial partial selection method through the arrangement of Figs. 1-12. The configuration of the reference keypad in this form is called "3 * 3 national language-number reference keypad" for convenience. In this case, the English alphabet is always placed at the bottom to maintain a consistent shape. Of course, in this case as well, the combination within the 3 * 4 keypad can be used to input a partial full selection method from the native language mode to the English alphabet.

It is obvious that mutual modification between these two types of reference keypads can be made by substituting contents arranged in the grid of each row on the button. In the embodiment of the present invention, "3 * 3 national language-number reference keypad" is presented.

The environment in which the subject matter of the present invention operates is shown briefly in FIGS. 1-13 and 1-14. The present invention describes a method for recognizing a combination of button presses and translating them into alphabets. The method proposed in the present invention may be implemented on the client (terminal) side or may be implemented on the server side. 1-13 is a diagram illustrating a function when implemented at the client side. A program that accepts button presses from the keypad and translates them into alphabets is loaded into the memory, and the memory receives the button presses from the control unit, interprets them, and displays the contents on the display unit (display window). If necessary, the generated alphabet may be transmitted to the server and used.

1-14 shows that only the DTMF tones are sent by the client and the DTMF tones are recognized by the server to interpret the input alphabet.

EXAMPLE

With reference to the accompanying drawings shows an embodiment for each language. The content mentioned once in one embodiment of the present invention may apply to the same content in other languages.

1.1 English

There are 26 English alphabets. About 3 alphabets can be assigned to the [1] – [9] buttons. In the case of English, since the standard is established and about 3 alphabets and symbols (.) Are assigned to the standard, the combination of left and right straight lines is selected in the partial selection method even if the standard grid or the alphabet is not highlighted. The user can intuitively see that it applies.

In order to be able to input the English alphabet and numbers by partial partial selection method within the 3 * 3 keypad, the position of the number on the button may be slightly different from the current general arrangement (three English alphabets below the number). See FIG. 2-1.

1.1.1 Application of the Standard Repeat Selection Method

In applying the standard repetition selection method, unlike the existing selection order, it can be selected according to the number of times the button is pressed in the order close to the reference grid. For example, in Figure 2-1, pressing button [3] once enters F, pressing twice enters E, pressing three times enters D, and pressing four times enters 3. Press button 8 once to enter U; twice to enter T; three times to enter V; four times to enter 8 Press button [4] once to enter G, press twice to enter H, press three times to enter I, and press four times to enter 4.

1.1.2 Example of Grid Reference Center

Furthermore, while maintaining the current alphabet assignments arranged per button, the high frequency of use of the three alphabets arranged for each button can be arranged in an order close to the reference grid to increase the input efficiency. See FIG. 2-1.

A description will be given based on the arrangement in FIG. 16. As described above, the alphabets are arranged around the reference grid while maintaining the existing alphabet group for each button of the English alphabet. However, considering the frequency of use of the alphabet, the alphabet with the highest frequency of use is placed at the reference grid position. The next most frequent alphabet in the group is placed near the reference grid. The method of inputting characters by partial partial selection method is the same as that described in the example of sequential arrangement. For example, in FIG. 2-2 U = [8] + [8], T = [8] + [7], and V = [8] + [9] are selected.

The advantage of this method is that it keeps the existing standard alphabet group on the button, so that the convenience of input can be achieved while utilizing the advantages used previously.

In the case of A, B, and C on the [2] button in Fig. 16, the vowel A is most frequently used, and thus is arranged at the position of the reference grid. [3] In the case of D, E and F on the button, the vowel E is placed at the position of the reference lattice because the frequency of use is the highest. [4] In the case of G, H and I on the button, the vowel I is also the reference lattice. Was placed in the position of. [7] In the case of T, R, and S on the button, S is placed at the position of the reference grid.

When input by the repetition selection method based on Figure 16, press the [3] button once to enter E, press twice to enter D, press three times to enter F, press four times to enter 3. Press button [8] once to enter U, twice to enter T, three times to enter V, and four times to enter 8. Press button [4] once to input I, twice to enter G, three times to enter H, and four times to enter 4. It is similar to the existing method, but differs in that it is selected by the order centering on the reference grid.

1.2 Other Roman Languages

The Roman languages are all English alphabets (hereafter called "basic alphabets") and subscripts (.., v, ^, /, //, / (in the middle of the alphabet), ＼,-, ~, s (alphabet) Bottom, yes. Etc.) are present. This is referred to herein as "modified alphabet" for convenience. In some languages, there are additional alphabets that are not in the English alphabet, but the number is small. This is called "additional alphabet".

You can configure the entire display pad by displaying all the variants of the alphabet used in a specific language or in a few languages you wish to type on the keypad. Which is ?? You only need to add the variant alphabet to the grid available in the English alphabet layout. When constructing the entire display pad, the modified alphabet can be used to position up and down combinations, diagonal combinations, etc., within the 3x2 grid on the button to which the basic alphabet belongs.

Another way is to place a variant alphabet control or subscript control on a particular button and select it. Selecting a control is possible using the partial full selection method, the standard repeat selection method, and the simple repeat selection method. However, subscript buttons should not be used in combination with other alphabets or other control inputs. If you use the control buttons repeatedly on a terminal with a display window (if you use the repeat selection method), you do not have to display the controls on the control buttons. The user only needs to know that the control button is a subscript button.

When inputting the modified alphabet, you can input the combination of the control and the basic alphabet. The control may be pre-input or post-input.

Several subscripts exist in the Roman language, but not all subscripts are used in a particular country's language, making it easier to select some subscripts that are only used in the alphabet of that country. That is, when subscript control is selected by partial partial selection method or reference repetition selection method, subscript controls used in the language are arranged in order of frequency of use in the order close to the reference grid, and subscript control is selected by simple repetition selection repetition method. Arrange them so that they can be selected in order of frequency of use. As mentioned, terminals with display windows do not need to display controls when the iterative selection method is applied to control selection.

For example, there is one type of subscript used in German (..) and five types of subscript used in French (/, ^, ＼, .., s). There may be cases where a French user wants to enter French primarily and German secondly. In this case, the five subscripts used in French are easily selected in order of frequency. If the frequency of the French variant alphabet subscripts is in the order of /, ^, ＼, .., s, when selecting a control using the repeat selection method, press the control button for the subscript once, /, press twice, ^, Press four times to select .. five times to select s. Of course, it is also possible to arrange subscripts in the order close to the reference grid of the subscript control button when the control is selected by the reference repetition selection method. The subscripts (..) used in German are already included in the subscripts used in French and need no further consideration.

On the contrary, if the German wants to input German first and French secondly, when selecting a control by the repeat selection method, when the control button is pressed once, the subscript used in German is selected. Press ^ for four times ＼ for five times or s for five times. The subscript .. should be selected first because it should be possible to enter German first, even if it is not frequently used in French.

Here, the additional alphabet β (Eschat), which is not often used in German, can be processed by placing it on an available grid on the button to which the basic alphabet S belongs, or by placing it on a grid on the [0] button that is not used for English alphabet placement. have. However, in order to process non-English alphabets with a single superscript control button, it is regarded as a modified alphabet so that the subscript control button is pressed once. Press three times /, four times ^, five times 번, six times s to select. After three button presses, the French subscript is selected (1st German, 2nd French). 3-1 shows an example in which a modified alphabet control button is used to place a control using [*]. The subscript control is combined with the basic alphabet to form one modified alphabet, but the additional alphabet β can be selected without the need for combining. That is, for control post input, β = [*] + [*], = a + [*].

Since countries in Europe are integrating politically, economically and socially, in the order of selection of subscripts used in the languages of the countries of the EU (ie, the order of placement), the first choice of subscripts used in their own languages should be chosen in order of frequency of use. The subscripts of the language selected by the user can be selected, and the subscripts of the remaining languages can be selected.

Disposable case switching buttons, which are important in the alphabetic input of the Roman language, can be processed using [#] or the like.

Some languages do not use some alphabets. However, as long as it is necessary to input the English alphabet together in the family language, all the English alphabets can be used.

The variations and additional alphabets present in each language are as follows.

1.2.1 German

Three variants of the alphabet on the basic English alphabet And one additional alphabet (β) are used. Only one (..) variant of the alphabet control is required. β can be disposed at positions where vertical combinations of keys belonging to S are possible, or placed on a grid on the [0] button. Alternatively, they can be placed on a control button for processing (ie selected by a combination of control buttons).

1.2.2 Vietnamese

In the basic alphabet of English, F, W, Z, etc. are not used, seven Modified alphabets are additionally used. Since there are four types of dot (v, ^, /,-) used in the variant alphabet, the control for the one-time mode switching is also required.

1.2.3 French

11 basic alphabets in English A variant of is used. There are five types of dot (/, ^, ＼, .., s) used in the variant alphabet.

1.2.4 Spanish

English basic alphabet, three additional alphabets (ch, ll, rr) and one variant alphabet This is used. Three additional alphabets (ch, ll, rr) can be treated as two basic alphabets. Can be handled as a one-time mode switching process or as a top-down combination of keys to which the basic alphabet belongs.

1.2.5 Italian

In the basic alphabet of English, alphabets except W, X, and Y are used.

1.2.6 Frenzy

Y is not used in the basic English alphabet, and additional alphanumeric characters are used. It can also be treated as two basic alphabets.

1.2.7 Czech

The basic English alphabet, eight variant alphabets (case in each case) and one additional alphabet (ch) are used. One additional alphabet can be treated as the base alphabet. In particular, all 16 variant alphabets consist of the letter "v" in the base alphabet. In other words, you only need to set one control for the one-time mode switch.

1.3 English

1.3.1 Composition of Korean

Contents applied to other languages among the contents described in the embodiments of the present Korean language are not mentioned again in the embodiments of the other languages. Assigning an alphabet to a button is called "assignment" or "assignment", and specifying "as far as" to which grid of the button the assigned alphabet is located.

The Korean alphabet consists of 10 consonants, 10 basic vowels, and 4 consonants. In addition, five consonant horns and four extended vowels are provided on the standard keyboard.

Due to the characteristics of Korean, one letter is formed by a combination of alphabets, and one letter is composed of a consonant (consonant) + neutral (vowel) + final (consonant) or a consonant (consonant) + neutral (vowel). It can be seen that the most frequently used is consonants. Consonants include flat sound, rhythm, and rhythm, and the common frequency of use is the order of rhyme, rhythm, and rhythm. Therefore, the overall frequency of use can be seen in the order of "consonant pyeonyum-basic vowel-extended vowel-consonant sound-consonant sound".

1.3.2 Example of placing Korean alphabet and numbers using a 2x2 grid

In arranging the Korean alphabet on the keypad using a 2x2 grid, 30 alphabets of 3 alphabetical letters can be arranged on 10 buttons [1] to [0]. On Korean standard keyboards, the number of alphabets is 33, but when using a 2x2 grid, only the most frequently used "ㅐ" out of the four extensions is placed. The rest of the extended collection can be treated as a combination of the default collection.

First, in the consonant arrangement, ten basic consonants, that is, consonant flat sound, may be arranged on the [1] to [0] buttons. The horn and the vowel can be arranged along with the corresponding basic consonants and 10 basic vowels and the extended vowel "ㅐ" in the remaining grid space.

As the input method, a partial partial selection method and a reference repetition selection method may be applied. When the standard repetition selection method is applied, the selection order is selected in the order of the order close to the reference lattice, that is, the alphabet of the reference lattice position, the alphabet of the left and right adjacent linear combination positions, the alphabet of the upper and lower adjacent linear combination positions, and the alphabet of the adjacent diagonal combination positions.

1.3.3 Example of Assigning Korean Alphabet and Numbers Using a 3x2 Grid

In assigning the Korean alphabet on the keypad using a 3x3 grid, 10 basic consonants are assigned to the [1]-[0] buttons, and 10 basic vowels are assigned to the [1]-[0] buttons, respectively. Can be. The simplest way of assigning is to assign sequentially. The present invention proposes a method of assigning a plurality of considerations such as identification of the representative consonant position and harmony with vowel assignment. You can also assign the sound and the sound to the same button in the same group as each basic consonant.

1.3.3.1 Korean Vowel Assignment

The vowels displayed on the keyboard are 10 basic vowels (ㅏ, ㅑ, ㅓ, ㅕ, ㅗ, ㅛ, TT, ㅠ, ㅡ, ㅣ) and 4 extended vowels (ㅐ, ㅒ, ㅔ, ㅖ). This was also done by assigning each button a row or column order. However, in the present invention, first, in consideration of the directionality of the basic vowel in the assignment of 10 basic vowels, ㅗ ㅛ to [1], [2] button, ㅏ 에 to [3], [6] button, respectively, ㅓ 에 for buttons [4], [7], ㅏ for buttons [3], [6], and 그리고 for buttons [8], [9] (or [9], [ 8] button). Of the four extended collections, ㅔ and 각각 are assigned to the buttons to which the default collection, ㅓ 각각 belongs, respectively. However, ㅐ and ㅒ have no space that can be processed by left and right linear combination on the button to which the basic vowel belongs. In the vowel assignment, the vowel is assigned to face the exterior (outward) in consideration of the up, down, left, and right directions of the vowel.

On the contrary, in assigning according to the vowel direction (up, down, left and right), it is also possible to assign to the inside (inward). In other words, TT 에 to [1] and [2] buttons, ㅓ ㅕ to [3] and [6] buttons, ㅏ 에 to [4] and [7] buttons, and ㅕ 각각 respectively. [3] and [6] buttons, and ㅗ ㅗ can be assigned to the [8] and [9] buttons (or [9] and [8] buttons), respectively (see FIG. 14).

When a pair of buttons ([1, 2] [3, 6] [4, 7] [8, 9]) where vowel pairs with up, down, left, and right directions are located is expressed in different colors, the entire keypad forms a letter shape. Another method is to assign vowel pairs to [1, 4] [2, 3] [6, 9] and [7, 8] button pairs. In particular, the reason for proposing the letter-shaped allocation is to use the letter-shaped to represent the order of the universe and to give meaning to those who possess or use it for their happiness.

Finally, ㅡ, ㅣ is assigned to the center button [5]. This is to use button [0] for space and control input. However, you can assign one vowel of ㅡ, ㅣ to [8] and ㅒ (ㅖ for inwards) to button [5].

The 10 basic collections are treated as adjacent left and right combinations, and the extended collection is assigned to the position of the two spaces.

1.3.3.2 Korean Consonant Assignment

Hangul consonants can be divided into 10 pyeongum, 4 of them have a pulsation and 5 have a sound. Regarding the assignment of consonants, there are ways to allocate the rhythm by dividing it into 10 groups centered on the rhythm. However, until now, the assignment to each button in order of consonant sound is mainly known. However, the consonant group need not be assigned by the order of consonants. In the present invention, the assignment of the consonant consonants with respect to the consonant group will be described with respect to the assignment of consonant consonants considering the order and shape. A description will be given with reference to FIG. 10.

First, a, b, and c are assigned to 1, 2, and 3, respectively. We have already explained why we assign tranquility to our position. ㄱ is the first consonant, so the shape is similar to 1, so assign it to 1 button. Also, c has 2 directions as the second consonant, and c is viewed from 3 directions as the third consonant so that it is located at button 2 and button 3, respectively. Next, place ㅁ on button 4. This is because ㅁ can be viewed in 4 directions and can be easily associated with button 4 intuitively.

And place o on button 5. This is because ㅇ has a circle shape, so it is natural to place it on the keypad (天元 button 5). ㅂ is placed on button 6. Is in the sixth in order and similar in shape to six. ㅅ is located at button 7. This is also the order and shape of the assignment. ㄹ is located at button 8. This is because r is similar to 8 in shape (since it is similar in shape to 2 but places b on the 2 button). Is located at button 9 and ㅎ at button 0. This also takes into account order and shape.

Unlike the above assignment, if you place o on a zero button similar in shape to o rather than on button 5, you intuitively place r on button 5 that is similar in shape and place it on button 8 that is similar in shape. Can be located.

In the above consonant allocation, consonant flat sound is placed in the position of all combinations within each button. The horn and the rhythm are placed on the button to which each consonant sound belongs. In the example of the two consonants mentioned above, only the consonants of the middle row (2, 5, 8, 0) are assigned with consonants and no consonants. Among the consonants belonging to the consonant group, the lowest frequency (two consonants) is treated as a vertical combination of vowels and vowels, and the vowels and vowels are treated as a combination of left and right. In particular, the basic vowels are treated as adjacent left and right linear combinations, and the extended vowels and septums are assigned to the positions of two spaces.

A grid of adjacent vertical and horizontal combinations of ㅁ remains, which assigns a period (.) That can be used most frequently among special characters.

The following table shows an example of the method of assigning each button centered on the basic consonant and the basic vowel.

As a variation of the consonant allocation method 1, it is possible to assign r to the [4] button and to assign ㅁ to the [5] button in consideration of the alphabetical order of the alphabet. In this method of consonant allocation, consonants and vowels are assigned in this way by assigning “b, ㄹ, ㅎ, ㅇ” where no rhymes and vowels exist, which is the center row on the keypad [2], [5], [8], [0] It is meant to be assigned to a button. The vowel assignment method 2 and the vowel assignment method 3 are variations of the vowel assignment method 1 (outward), and only the portions shown in gray differ from the vowel assignment method 1. The same modification can be made for vowel assignment method 4 (inward). For an example of consonant allocation method 1, see FIG. 4-1, and for an example of vowel assignment method 1, see FIG. 4-2.

1.3.3.3 Arrangement of Korean Consonants and Vowels

As mentioned, the common frequency of use in Korean is the order of "pyeongum-basic vowel-extended vowel-vowel-hom". The following table shows the consonant and vowel assignment methods combined by consonant and vowel. Alphabetical grouping of each button is arranged in order of closest standard grid. In applying the order close to the reference grid, that is, the convenience order of the button combination, the consideration factors are applied in the order of "Equal combination-left combination-straight combination-diagonal combination" which is a universally applicable standard. Here, 2 ^nd , 3 ^rd , 4 ^th , 5 ^th, etc., indicate the order close to the reference lattice, and are the selection order when the standard repetition selection method is applied. If no alphabet is placed at 4th here, it is obvious that a number is selected at 4th.

For an example of the combination of the consonant allocation method 1 and the vowel allocation method 1, see FIG. 4-3.

1.3.4 Advantages of Applying the (Ref) Selection Method in Korean

The iterative selection method can be applied based on the Korean keypad presented in the present invention. According to the number of button presses, the alphabet is selected in the order close to the position of the reference grid. In the application of the repetitive selection method to Korean of the present invention, the order close to the reference lattice is the order of the reference lattice, adjacent left and right linear combinations, left and right linear combinations, vertical straight combinations, and adjacent diagonal combinations. Applicable to all Korean embodiments presented in the present invention.

For convenience, referring to Fig. 4-3, pressing button [1] once will select a, pressing twice will select ㅗ, pressing three times will select ㅋ, pressing four times will select ,, and pressing five times will select 1. will be. Likewise, pressing button 2 once selects b, pressing twice selects 되고, pressing three times selects ㅐ, and pressing four times selects 2. In the same way, press button [3] once to select c, twice to select ㅏ, three times to select 되고, four times to select ,, and five times to select 3.

Advantages of applying the iterative selection method to FIG. 4-3 are as follows. The basic consonants are treated as one presses, and the basic vowels are treated as two presses. Since the basic consonants are used as initial and final constellations, the total number of inputs can be minimized. Considering that one letter is composed of only the first + neutral only in Korean, about half of the letters can be input in three letters, and the other half of the initial + neutral + final is 4 Since it is possible to input tarot, it is possible to input Hangul Hangul characters with an average of 3.5 Tarot. This is similar to or even surpasses the number of strokes in the currently used character input method.

There is also ambiguity in the input, but it is significantly reduced. For example, to enter "ga", you must enter [1] + [3] + [3] as shown in FIG. 10, but can be recognized as "ga" even if you enter [1] + [3] + [3]. have. 13 for this is not "a". The double bearing is not a general case, which is very helpful in the general case.

1.3.5 Alternate Alphabet Processing (Example of Arrangement of Korean Alphabet Using 3x1 Grid)

The consonants can be removed from the arrangement of "Consonant Assignment 1 + Vowel Assignment 1" and only the remaining alphabets can be placed. The horn is regarded as the modified alphabet of the corresponding flat sound and the [*] or [#] button is used as the modified alphabet control button. The sound may be regarded as a subsequent alphabet of the sound. For example, if you use [*] as a modified alphabet control button and apply the control button input, ㄲ = [*] + a. When applying the modified alphanumeric control button, ㄲ = ㄱ + [*]. Since only one control is placed on the control button, there is no need to apply the partial full selection method to the selection of the control. See Figures 4-4.

In inputting the alphabet displayed on the simple keypad, either the partial partial selection method or the standard repeat selection method can be applied. When the simple keypad is configured and the standard repetition selection method is applied, the flat sound can be inputted with one stroke and the basic vowel can be inputted with two strokes, thereby reducing the number of inputs. This means that the simple reference selection method can be applied to the simple reference keypad configured as above. To simplify the simple reference keypad, the simple keypad is configured by simply placing the alphabets arranged in the order close to the reference grid on the reference brief keypad without the concept of the reference grid.

1.3.6 Modified Alphabet Processing of Sound and Sound and Combination or Modified Alphabet Processing of Extended Collection (Example when Korean Alphabet is placed using 2x1 Grid)

Reflecting the characteristics of Korean language, 10 basic consonants can be arranged at the position of the reference lattice with the representative alphabet, and 10 basic vowels can be arranged at the position of the right and left combination. Only basic consonants and basic vowels can be arranged using a 2x1 grid. Alternatively, you can use the 3x1 grid to place the basic consonants, basic vowels and numbers. See Figure 4-5.

It can be regarded and treated as a modified alphabet (or subsequent alphabet) of the basic consonant corresponding to the sound and the sound. Since the sound is generally used more frequently than the sound, it can be considered that the sound is placed at the reference grid position of the modified alphabet control button. Since it is placed on the control button and there are two controls to choose from (beep, beep), it is good to apply the repetitive selection method in selecting the control. You can use the [*] or [#] button as a modified alphabet control button.

For example, if you use [*] as the transform alphabet control button and apply the control button input, it will be ㅋ = [*] + a, ㄲ = [*] + [*] + a. Since there is no sound in ㅅ, ㅆ = [*] + ㅅ, and ㅆ = [*] + [*] + ㅅ. In this example, the modified alphabet control button for consonants is simply referred to as "consonant control button". The partial partial selection method or the reference repetition selection method can be applied to the selection of the basic consonant "a" displayed on the keypad.

The extended collection can be entered as a combination of basic collections. For example, ㅔ = ㅓ + ㅣ The partial partial selection method and the reference repetition selection method are applicable to the selection of "ㅓ", which is also displayed on the keypad. When the above method is applied, even if the repeated selection method is applied to Korean input, there is almost no ambiguity.

Ambiguity exists only if the base vowel is repeated more than three times (eg base vowel + extended vowel). For example, "why" consists of "ㅇ + ㅗ + ㅏ + ㅣ". When input using a combination of basic vowels, "ㅏ" between vowels and vowels can be recognized as two consonants. I.e. "why"=> Or => Can be recognized as "why". Only in this case, it should be input separately through time delay. This case occurs very rarely in the case of "ㅙ, ㅞ", etc. in Korean.

In practice, however, the ambiguity in the repetitive selection method occurs when three or more letters are input, that is, when three or more alphabets are placed on one button, and when only one or two letters are used, the experiment is performed with little ambiguity. You can see it. Thus, in fact, there is little ambiguity even if the vowel control is not handled by the extended collection.

By inputting the basic alphabets (20 pieces) by the repetitive selection method, the ambiguity can be completely eliminated by placing the extended collection as a modified alphabet of the corresponding basic collection and placing a modified alphabet control button for the vowel. For example, if you apply the Repeat selection method to the default letter, set the variant alphabet control button for vowel to [#] and apply the control button input, ㅔ = [#] + ㅓ, ㅖ = [#] + ㅕ , ㅐ = [#] + ㅏ, ㅒ = [#] + ㅑ Applying the postal variant alphanumeric control button 입력 = ㅓ + [#], ㅖ = ㅖ + [#], ㅐ = ㅏ + [#], ㅒ = ㅑ + [#]. In this example, the variant alphabet control button for this vowel is referred to simply as the "collection control button".

Similarly, for the double vowels (ㅢ, ㅟ, ㅚ, etc., the double vowels combined with "vowels" vowels are called "similar extended vowels" for convenience) in parallel with the combination of the basic vowels. Applicable For example, if you use the [#] button and apply the post-input, you have ㅢ = ㅡ + [#], ㅟ = TT + [#], ㅚ = ㅗ + [#], and so on.

The reason for the ambiguity by applying the consonant control method and the vowel control method is as follows. The composition of Hangul has the following regularity. The composition of one letter of Hangul is one of the following forms. Vowels mean basic vowels. The parentheses mean the following letters:

1.ja + mo (+ ja + mo + ...)

2. Child + Mother + Child (+ Child + Mother + ...)

3. Child + Mother + Mother (+ Child + Mother + Mother)

4. Child + Mother + Mother + Child (+ Child + Mother + Child)

5. Child + Mother + Mother + Child + Children (+ Child + Mother + ...)

6. Child + Mother + Mother + Mother + Mother (+ Mother + Mother + Mother)

If the vowel (the main vowel) is repeated three times, the middle vowel can be recognized as two consonants, so there can only be ambiguity. This can eliminate ambiguity by handling the vowel control buttons on the expansion bar. As in the example, the vowel control buttons use a different button than the consonant control buttons to completely eliminate ambiguity.

Consonants have a regularity that can be repeated up to three times. Consonant bearings do not repeat the same consonants. The basic consonants are all composed of different buttons, and the sound and the sound are treated as control buttons, so the consonants have no ambiguity in the repeating structure. Very rarely, if the second and third consonants of the three consonants in the fifth case are the same consonant, they can be recognized as vowels, and can only be ambiguous when combined with subsequent vowels to form a double vowel. For example, three consonants of "d-a-a" are repeated in "dirt", and "a-a" is recognized as a vowel and combined with a subsequent vowel "ㅣ" to form a double vowel. => "Light" and vice versa "cloud" => "dirt". According to the literature, however, this case is virtually negligible as 0.0x%, and the word actually used is followed by a double brace after which there is generally no initial "no" value, and the double brace does not end with "ㅇ". .

This means that the simple reference keypad in the present embodiment may be applied to only the repetition selection method. To simplify the standard keypad means to simply arrange the alphabets arranged in the order close to the reference grid on the button from left to right or right to left collectively.

However, the vowel control button ([#] in the example) should not be used as a combination for inputting other characters, so do not become [0] + [#] when entering "ㅣ" by partial partial selection method. For example, it can arrange | position so that it may become [0] + [8].

1.3.7 Compatibility between the global display pad and the lightweight keypad

Even if each button on the Quick Reference Keypad is not marked with a beep and a beep, it is easy to remember that the beep can be selected by right-and-left straight combinations in the partial full selection method, and that the beep is selected third in the iterative selection method. have. For the user memorizing this, it is possible to select the partial sound selection in parallel with the partial full selection method or the standard repetition selection method. The same is true for the sound (up and down linear combination, 4 times).

As in the case of consonants, even when the extended collection is not displayed on the simple reference keypad, the partial full selection method is applied to the entire display reference keypad (FIG. 4-3) that is compatible with the simple reference keypad of FIGS. 4-5. For = [4] + [5]) and ㅕ (= [7] + [8]), "(= [4] + [6]) and ㅖ (= [7] + [9]) Fine combination "and 에 (= [2] + [3]) and ㅒ (= for ㅏ (= [3] + [2]) and ㅑ (= [6] + [5]). It is easy to remember that [5] + [6]) form a "facing combination". Therefore, for such a user, the extended collection can be allowed to be input by the input method (partial full selection method and reference repeat selection method) on the entire display reference keypad.

Similarly, the entire display standard keypad can be input by the partial full selection method or the standard repeated selection method by using the vowel sound, the horn sound, the extended vowel, the similar expanded vowel, and the consonant modified alphabet control method and the vowel modified alphabet control method. Can allow to process.

This may be equally applied to the case where the standard keypad is simplified.

1.3.8 Simple keypad of standard keypad

The keypad proposed in the present invention is a keypad to which both the partial partial selection method and the repeated selection method can be applied. However, for users who prefer the repeat selection method, we can think of the keypad only for the repeat selection method by changing the arrangement of characters on the keypad. That is, the alphabets on the keypad are sequentially arranged in the order of selection. In this case, when the left-right combination is used, the buttons in the first row ([1], [4], and [7] buttons) remain unchanged, and the buttons in the second row ([2], [5], [8], and [0] do not change. Button) will change the position of the first alphabet and the second alphabet, and the three rows of buttons ([3], [6], [9] buttons) will change the positions of the first and third alphabets.

1.3.9 Input Method Using Character Completion Key in Korean

A similar method can be applied to the existing method but also to the Korean keypad of the present invention. In the case of the linear combination of left and right and vertically adjacent applications (Figs. 10 and 15), since the basic vowels are distributed evenly throughout the keyboard, pressing the button once selects the basic consonant (super initial), and then pressing the basic vowel again You can have a vowel (neutral) selected. If you want to select the extended vowel (neutral), you must press twice in succession. If you press the one-character completion key ([#] button), the Hangul character is completed. In order to input a horn, a vowel, and a double vowel, the horn, the vowel, and the double vowel on the corresponding button can be selected by pressing a function key ([*] button) in advance and then inputting the button.

For example, in Figure 10, press * 1 to select, and * 11 to select ㄲ. Similarly for double vowels, press * 4 to select 다음 에 after vowel, and * 44 to select ㅔ. However, the ambiguity of input exists in applying this method, so it is still necessary to distinguish by time delay. In addition, many exceptions must be considered by the user, and there is a big blind spot that a letter completion key must be entered for each character completion.

1.4 Japanese

There are 46 Japanese alphabets. Approximately five assignments per button are possible.

In addition, there may be a method of applying consideration elements in the order of "equal combination-left-right combination-adjacent combination-straight combination" in the utilization of the button grid. In this case, the 3 * 3 keypad uses left-right straight combination, up-and-down adjacent straight combination, and adjacent diagonal combination. This uses a 3x2 grid for alphabetic placement and can efficiently utilize grid space on the buttons.

There may be a method of applying consideration elements in the order of "equal combination-straight combination-left and right combination-adjacent combination" in the utilization of the button grid. In this case, the 3 * 3 keypad uses the left and right up and down linear combination. This will use a 3x3 grid for alphabetic placement.

1.4.1 How to assign Japanese alphabet

The following methods can be used to group and assign the 46 alphabets to each button.

In the center of the reference lattice, it is preferable to place the alphabet that has a relatively high frequency of use at the reference lattice position and can represent the group of alphabets located on the corresponding button, あ line (あ, か, さ, ... や, ら), The alphabet is relatively frequently used and can be regarded as the alphabet representing each stage. Therefore, the alphabet of line A can be placed at the position of the reference grid.

In Method 1, in the grouping of alphabets by buttons, three letters and two letters are present in yadan and yadan, and two letters are similar in pronunciation. It is tied to one button.

Method 2 is a variation of Method 2, implicitly assigning n to another button to use the [0] button as a control button. It is assumed here that it is assigned to the [9] button.

Method 3 combines the alphabet of each column into an alphabetic group and places ん in the tenth column. Three alphabets are assigned only to the [8] and [0] buttons.

In each method, "horizontal writing priority arrangement" and "vertical writing priority arrangement" may be applied in arranging the alphabet in "order close to the reference grid". In the case of Japanese, the reason for suggesting vertical writing priority is that vertical writing is still widely used in Japanese culture, which is useful in the arrangement and identification of alphabets. An example of an arrangement based on the assignment of method 1 is as follows.

An example of arranging alphabets of each group by first considering horizontal writing (left and right combination) in the order close to the reference grid using a 3x2 grid is shown in FIG.

An example of arranging alphabets of each group by first considering vertical writing (up-and-down combination) in the order close to the reference grid using a 3x2 grid is shown in FIG.

An example of arranging alphabets of each group by first considering horizontal writing (left and right combination) in the order close to the reference grid using left and right linear combination of a 3 * 3 keypad is shown in FIG.

Fig. 19 shows an example in which the alphabets of the groups are arranged by first considering vertical writing (up and down combination) in the order close to the reference grid by using the left and right linear combination of the 3 * 3 keypad.

In the above Japanese embodiment, when the reference repetition selection method is applied, it may be selected in alphabetical order according to the number of times the button is pressed. Press button [1] once to select あ, press twice to select い, press three times to select う, press four times to select え, press five times to select お, and press six times to select 1.

In the arrangement of the alphabets, there may be a method of arranging the alphabets in order without representing alphabets of the line A in the standard grid of each button. An example of sequentially placing alphabets in a horizontal priority using a 3x2 grid can be seen in FIG. 20. In this case, if you input す as the partial partial selection method, す = [3] + [3]. In this case, it may be regarded as a simple keypad to which the repetitive selection method is applied, and may be selected in alphabetical order.

1.4.2 Japanese Modified Alphabet Processing and Alphabetical Input Using Subsequent Control Buttons

In Japanese, there are variations of long sound (represented in small letters), turbid sound (with two dots (") on the right side of the letter), and half-tone sound (with a small circle (o) on the right side of the letter). By applying the repeated selection method of the modified alphabet control, each control can be selected according to the number of times the control button is pressed, in which case the user does not need to display the control (long sound, sound, and halftone) on the control button. Just know that the button is a modified alphabet control button.

Use [*] as the transform alphabet control button, select the control by repeat selection method, and ぎ = き + [*] + [*] when applying the input after control.

Furthermore, subsequent control for character entry is possible to simplify the alphabetical arrangement on the keypad. In Japanese, there are 46 alphabets, and it is difficult to display them all on the keypad. Therefore, in the exemplary embodiment of the application, only the alphabets representing the position of the reference lattice, that is, the lines of あ (あ, か, さ, ... や, ら) are displayed on the button, and the remaining alphabets (eg, い of あ line) are displayed. , う, え, お) allows subsequent controls to be selected by pre- or post-input.

The subsequent keypad is constructed from FIGS. 5-1 to 5-4 as follows.

When the subsequent control button is set to [#] (assuming the superscript control is [*]), and the subsequent control button is entered later, for example, あ [1] (only one alphabet is displayed on the button. It is not necessary to apply the partial preselection method to the alphabet selection), い input あ + [#] (ie [1] + [#]), う input [1] + [#] + [#], えWhen inputting [1] + [#] + [#] + [#], お input [1] + [#] + [#] + [#] + [#]. In this case, the average number of pushes is three times, but only one alphabet representing a group of buttons on the button can be displayed, and unlike the simple repetitive input method, there is an advantage of no ambiguity of input. See Figures 5-6.

As another example, set subsequent control buttons to [*] and [#], and enter the second to third alphabets (eg い, う) and the fourth to fifth alphabets (eg え, お). Can be used as a subsequent control for In other words, when input あ [1], い input [1] + [*], う input [1] + [*] + [*], え input [1] + [#], お input [ Enter 1] + [#] + [#]. In this case, the average number of pushes is 2.2 and there is no ambiguity in the input. In this case, the second to third control buttons [*] are used to allow the fourth to fifth control. [1] + [*] + [*] + [*], and [1] + [*] Can be + [*] + [*] + [*]. See FIGS. 5-7.

The disadvantage of using the [*] and [#] buttons as a follow-on control button is that subscript buttons cannot be assigned from a 3 * 4 keypad. In this case, n arranged at the [0] button can be placed at any one of the [1] to [9] buttons, and the [0] button can be used as a subscript control button (or a subsequent control button). If you place ん on the [9] button, you can enter [9] + [#] + [#] + [#] when you enter ん (subsequent control pre-input).

See FIG. 5-7.

5-6 and 5-7, the "あ ア" control means a mode change of the word unit between hiragana and katakana. It can be compared that the general mode switching is continuous mode switching, and that the long, turbid, and half-tone control are the alphabetical mode switching controls. Katakana is usually used intermittently and in single words in a sentence. In this case, instead of switching to Katakana mode and entering the alphabet, and then switching back to Hiragana mode, the Hiragana mode will automatically switch to Hiragana mode when the "あ ア" control is inputted (selected) and a single word is entered. . The "あ ア" control can be pre-input or post-in, just like any other control.

1.5 Arabic

1.5.1 Arrangement of the Arabic Alphabet

First of all, there are 28 letters in Arabic. This can accommodate 27 characters by applying the left and right linear combinations to the [1] to [9] buttons, and the remaining one character can be placed on the [0] button. Each Arabic alphabet has a numerical meaning. The following is the Arabic alphabet and the corresponding numbers.

In Arabic, when placing the alphabet on each button, the [1] button has the meaning of 1, 10, 100. ), And the [2] button has an alphabet meaning 2, 20, or 200 ( ) Can be assigned. The same applies to the [3] to [9] buttons. One alphabet with the remaining 1000 meanings can be assigned to the [0] button. That is, an alphabet group having a meaning of a number beginning with 1 is placed on button [1] (except 1000 meaning alphabets), and an alphabet group having a meaning of a number beginning with 2 is input on button [2]. .

In applying the partial partial selection method based on this arrangement, a character having a meaning of 1 to 9 is arranged at the reference grid position of the [1] to [9] buttons. This is because an alphabet representing 1 to 9 can be a character representing each group. An alphabet having a meaning of 10 to 90 is arranged in a position close to the reference grid (not described as a physically close position as described above, but in a lattice of a position close to the convenience of input, that is, a lattice of a right and left adjacent linear combination position here). In addition, the alphabet having a meaning of 100 to 900 is placed on the remaining grids. The remaining alphabet of 1000 is placed on the reference grid of the [0] button. As already explained, the position close to the reference grid can depend on the emotion and personal taste of the people. In the case of Arabs, horizontal writing is used, but as in the usual case, horizontal writing from left to right (hereinafter simply referred to as "left to right") is not used. "." Therefore, in determining the grid close to the reference grid for the [2], [5], [8], and [0] buttons in the center column, do not apply the grid located to the left of the reference grid. You can apply a located grid (as you write from right to left). The above is summarized in FIG. 6-1.

When the alphabet is input to the keypad of FIG. 1 by the partial partial selection method, for example, it has a meaning of 6. Enter [6] + [6] and have the meaning of 60. Enter [6] + [5], which means 600 Enter [6] + [4]. The same is true for the remaining buttons.

When the alphabet is input by applying the repetition selection method to the keypad of FIG. 1, for example, has a meaning of 6. Enter [6] and enter 60. Enter [6] + [6] and enter 600. Enter [6] + [6] + [6]. At this time, it means 60 for the generation who is used to right and left Enter [6] + [6] + [6] and enter 600. It is also possible to input [6] + [6] when inputting.

The method for inputting the English alphabet is the same as the one presented in the earlier application. That is, for example, by pressing the partial partial selection method, [4] + [*] is pressed when entering G in Arabic mode, and [4] + [4] is pressed when entering G in English mode. Repeat method in English mode is the same as the existing method.

In FIG. 1, in determining a lattice close to the reference lattice for the [2], [5], [8], and [0] buttons in the center column, a lattice positioned to the left of the reference lattice, which is a general method, may be applied. Then, the alphabets arranged around the reference grids in the center column are arranged to be interchanged with each other. The drawings are omitted. In this case, the input method is similar to that of FIG. 1 in the partial partial selection method and the repeated selection method.

Also, in the arrangement of the English alphabet due to the characteristics of the Arabs (right-left writing), it is possible to arrange the alphabet from the right side (right-right arrangement) without placing the alphabet from the left side. Possible placement of the English alphabet in Arabic is shown in Figure 6-2.

The presented keypad is a keypad that can apply both partial selection method and repetitive selection method. However, for users who prefer the repeat selection method, we can think of the keypad only for the repeat selection method by changing the arrangement of characters on the keypad. That is, the alphabets on the keypad are sequentially arranged in the order of selection.

Also in this case, in consideration of the characteristics of the Arabic language (right-left writing), as in FIG. 2 of the English alphabet, a method of sequentially arranging the alphabet from right to left may be considered. This can be seen in Figures 6-3. 6-3 illustrates a keypad dedicated to the repeated input method of FIG. 6-1.

In the button [1] in Figure 3, the alphabet means 100, 10, 1 Are arranged in sequence, and the same is true for the remaining buttons.

However, for Arabs who are familiar with left and right writing, the alphabet means 1, 10, and 100 on button [1] as shown in FIG. There is also a method to arrange sequentially.

1.5.2 Modified Alphabet Processing of Arabic Vowels

Arabic vowels can be made with specific symbols above or below the consonant (but it is rarely used). Thus, consonants combined with vowels can be treated as variants of the consonants. That is, the vowel code can be selected each time the subscript button is pressed. Alternatively, you can place a vowel control on a subscript control button (variable alphabet control button) and select it using the partial subselect method.

Likewise, vowels can be selected each time the subscript control button is pressed in the order of frequent use. The most commonly used vowels are three short vowels (Fatha, Kasra, Dharma), Sukun and Shota. Therefore, these five vowels are arranged in the order close to the reference grid of the subscript control button or selected according to the number of presses.

The remaining vowels include three long vowels, two double vowels, two auxiliary vowels, eldest, Alif Maksura, and Deger Alif. It can also be selected in order of frequency of use.

Since the number of vowels is very large, five vowels that are frequently used are treated as one subscript control button (for example, [*]) rather than one subscript control button for the variant alphabet, and the remaining vowels Can be treated as another subscript control button (for example [#]).

1.6 Hindi

1.6.1 Assignment and Placement of the Alphabet (Reference Keypad Configuration)

First, there are 11 vowels and 35 consonants in Hindi. There are a total of 46 alphabets, which is similarly applicable to the Japanese case in the embodiment. In other words, the arrangement grid can be applied to the left and right linear combination, or the left and right linear combination and the diagonal combination can be applied. In the arrangement order, sequential arrangement or reference grid center arrangement can be applied, and horizontal writing priority (left and right) or vertical writing priority (up and down) can also be applied. Considering the convenience of button combinations, the left and right combinations can be given priority or the top and bottom combinations can be given priority.

And again it is necessary to group consonants and vowels properly. There are 11 vowels in Hindi. And vowels for each Each vowel, except, has an abbreviation when combined with consonants.

In Hindi, vowels are often abbreviated in combination with consonants. Therefore, in the arrangement of the alphabet, the vowels are strongly differentiated from each other by consonant with the consonants. The remaining vowels are preferably abbreviated in the grid of buttons.

You can see that the 10 vowels except for are paired in two, one short and one long. Is the least used vowel. In the arrangement of vowels in Hindi, there may be a method of assigning 10 pairs of vowels sequentially to 10 buttons of [1], [2], ..., [0]. This may be referred to FIG. 7-1. In Fig. 7-1, the position of the vowel alphabet in a particular grid of buttons is determined in the arrangement with consonants. Can also be arranged in consideration of its arrangement with consonants (assigned to button [9] in the example of consonant placement below).

In addition, as in the case of Korean, there may be a method of arranging buttons on a keypad in order to maximize recognition of alphabetical positions. Likewise, groups of buttons are divided into ([1], [2]), ([3], [6]), ([4], [7]), ([8], [9]), ([5], [0]), ([1], [4]), ([2], [3]), ([7], [8]), ([4], [9]), ( [5], [0]). In the former case only, e.g. [1, 2] buttons respectively And assign them to the [3, 6] buttons, respectively. And assign them to the [4, 7] buttons, respectively. And assign them to the [8, 9] buttons, respectively. And assign them to the [5, 0] buttons, respectively. Can be assigned. Finally Can be assigned in consideration of the consonant assignment (assigned to button [9] in the example of consonant assignment below).

And there are 35 consonants: A circle means a group of consonants.

Similarly to Japanese, 45 alphabets can be accommodated in Hindi by placing five alphabetical letters each on nine buttons [1] to [9]. Therefore, it is necessary to group about four consonants (three buttons only), and there may be a method of grouping as above in consideration of pronunciation. The method of dividing each consonant group may be a variation of the above method.

In addition, it is possible to arrange the representative alphabet most frequently used in the arrangement of the consonant groups at the position of the reference lattice on behalf of each group. In this specification, the most frequently used in the above group Place as a representative consonant at the position of the reference grid of the [1]-[9] buttons. In the arrangement order of the consonant groups, the consonant groups containing such representative consonants can be arranged in the [1] to [9] buttons in order. There may be variations in the allocation of each button in the consonant group. See FIG. 7-2.

In addition to the above consonants, there are five consonants that are used only in foreign languages. All of them are represented by the dot below the consonant. Pointed below Pointed below Pointed below Pointed below Pointed below And so on. Since they are not frequently used, they suggest a way to handle them through modified alphabet control (subscript control).

Hindi letters consist of "consonants + vowels + (consonants)", "consonants + vowels" or "vowels + consonants" form, so that the representative consonants frequently used in the consonant group at the position of the reference grid and close to the reference grid Position ", you can place the vowels of each pair described above. There are three consonants in the vowels with similar pronunciation Can be placed together.

Including the above contents, an example of arranging alphabetical groups arranged for each button in the order close to the reference grid is as follows. However, it can be modified little by little depending on the frequency of use of the detailed alphabet.

In applying the order close to the reference grid, it may vary according to horizontal writing priority (left and right right), vertical writing priority (up and down right). As in the Japanese embodiment, various types of arrangements are possible. See FIG. 7-3.

According to Fig. 7-3, an example of the input by the partial partial selection method is shown in alphabet. Select [1] + [1] and select vowel When selected, enter [1] + [2]. Select [1] + [3]. When selected, enter [1] + [4], When selecting, enter [1] + [5]. When selecting number (1), enter [1] + [6].

Likewise, when applying the repeat selection method according to Fig. 7-3, pressing the [1] button once Is selected, press twice Is selected, press three times Is selected, press four times Is selected, press five times Is selected, press six times to select the number (1).

It is also possible to simplify the standard keypad. This is to arrange the alphabet in the order close to the reference grid presented above on each button can refer to the case of Korean in the embodiment.

1.6.2 Modified Alpha Processing and Subsequent Control Methods in Hindi (Simplified Keypad Configuration)

In Hindi. Subscripts such as (upper point-inverse nonconsonant code), (non-consonant sign), and.

It can be selected according to the number of times the subscript control button is pressed in the order of frequency of use, and can also be arranged in a close order from the reference grid of the subscript control button according to the frequency of use.

For example, the use of subscripts is. (Top), ＿ (non-consonant),. (Bottom), and so on. Use the control button as [*] and apply pre-input If you want to enter, press [*] + [*] + [*] + By typing

For Hindi, Korean and Japanese are applicable. In other words, in the case of representative consonants and vowels, Korean is applied (basic consonants are placed on the reference grid, vowels are placed on the grid closest to the reference grid), and subsequent control buttons are selected for consonants other than the representative consonants located on the reference grid. You can enter a letter after the / and enter a representative consonant so that you can select a different alphabet. In this case a vowel By placing on the [0] button, two alphabetic arrangements per button allows for a more compact arrangement and a simplified keypad. See Figure 7-4.

For example, using the subsequent control buttons as [#] and applying the input after the control buttons When you enter It becomes In arranging alphabets other than the representative consonants in the reference keypad, the arrangement is made with the frequency of use. If the consonants other than the representative consonants are arranged in alphabetical order in advance, close to the reference grid, At input Becomes ( Is 3rd in alphabetical order in the group).

The advantages of configuring the simplified keypad are as follows. Hindi, like Korean, mainly consists of syllables in the form of "consonants + vowels" or "consonants + vowels + consonants" and these structures are repeated to form words. Theoretically, consonants cannot occur more than once in a row. Vowel Is abbreviated and omitted if it comes after the consonant. Thus, in such cases only two or more consonants may be listed. As explained in the case of Korean, in a language having a structure of repeated consonants and vowels, the most frequently used representative consonants are placed at the reference lattice, and when the representative consonants and vowels arranged on the keypad are selected by the reference repetition selection method, There is no ambiguity between consonants, and when two consonants are recognized as one vowel, ambiguity occurs only when another vowel is recognized as two representative consonants. Also, in the number of input strokes, the most common representative consonants can be input in one stroke, and the next most frequently used vowel can be input in two strokes, thereby minimizing the overall input stroke.

In the case of Hindi, however, the number of subsequent alphabets is three for each button. Therefore, the two most frequently used consonants of the four consonants arranged per button are placed on each button, and each of the two consonants has one subsequent alphabet, and the number of strokes for control selection is repeatedly determined. Can be reduced. In other words Is As a follow-up alphabet, Is Is followed by an alphabet, and the button Wow Is placed. However, in this case, since two consonants and one vowel are arranged in one button, there is a disadvantage in that ambiguity is increased when the reference repetition selection method is applied.

1.6.3 Compatibility

As in the case of Korean and Japanese, the user who remembers the alphabet layout of the entire display pad can use the partial partial selection method or the standard repetition selection method for inputting subsequent alphabets on the simplified keypad or vice versa. Subsequent alphabets can also be entered by subsequent control methods.

1.7 Thai

1.7.1 Thai Consonant Placement

You can configure the entire display pad and a simplified keypad. Therefore, there is a method of arranging all consonants on the keypad, and a method of extracting and arranging some representative consonants.

The Thai consonants consist of 44 (only 42 are used), and there are 21 notes. There are a method of arranging all 42 consonants, and it is possible to extract and arrange 21 most representative consonants for 21 sounds. In consideration of the arrangement of the basic vowels (9) or the vowel alphabet elements, two [1] to [9] buttons can be arranged, and three representative consonants can be arranged to the [0] button. Alternatively, it is possible to place 21 basic consonants on seven buttons, three on one button.

In placing two or three representative consonants on each button, it is useful to group in consideration of pronunciation. Subsequent control buttons can be used for the rest of the alphabet for each note that is not frequently used.

The corresponding alphabet and pronunciation of 21 sounds is as follows: The first alphabet shown in each sequence is a frequently used alphabet, with 21 representative letters.

The order (*) in the table above means that there are two commonly used alphabets in the sequence. In other words, the most common consonants in the Thai alphabet are the 27 consonants, the first 21 letters of the 21 phonetic alphabets above, and the six alphabets marked with an asterisk (*).

If only 21 representative consonants are displayed on the keypad, the remaining unconsonated consonants can be entered in combination with the subsequent control buttons and the representative consonants.

The following is an example of grouping all 42 consonants and placing them on the keypad. If you place them evenly across the buttons, you may want to consider four to five placements per button. The following is an example of arrangement considering number and pronunciation. If you place only a few buttons (eg seven buttons), you can place six alphabets per button on a 3x2 grid.

Only 21 representative consonants are grouped and placed on the keypad as follows.

This arrangement is an example in consideration of the similarity of pronunciation. In the arrangement on the keypad, only the first marked representative consonant is arranged for each note. That is, only 21 representative consonants indicated by the square are arranged on the button, and the remaining consonants are inputted in combination with the subsequent control to the subsequent alphabet of the representative consonants. The sequence below the representative consonants is a subordinate order of the subsequent alphabet.

It is also useful to simplify the arrangement of the keypad to display only 9 or 10 representative consonants instead of 21. This can be done by selecting only one representative consonant per button in grouping of 21 representative consonants. Again, the rest of the alphabet can be processed using subsequent control buttons. However, there are difficulties in memorizing that different pronunciation alphabets belong to a specific representative consonant group and disadvantages in that the number of pressing of the control button increases.

In designating the remaining consonants belonging to the representative consonants (that is, the consonants that are not displayed on the keypad and processed through the subsequent control buttons), it is possible to classify by pronunciation and classify by shape. In other words, the same alphabet belongs to a group of representative consonants according to the pronunciation, but belongs to a group of other representative consonants with different pronunciations but similar shapes. The selection may be performed in parallel, for example, when a consonant which is primarily the same or similar sound is selected by a subsequent control button, and when all of the consonants have passed, a second consonant similar in shape is selected.

1.7.2 How to arrange Thai vowels

There are nine basic collections in Thai. For each of the nine there are short and long notes. Nine single notes can be a representative collection, or nine notes can be a representative collection. The rest of the vowels can be entered by subsequent control to the representative collection. Representing the nine long vowels is simpler than the short vowel, so the keypad as a whole can be slightly simplified.

As in the case of consonants, in the case of vowels, it is possible to classify by vowel in designating the remaining vowels belonging to the representative consonants (ie, vowels not displayed on the keypad and processed through subsequent control buttons). It is possible. Of course, it is also possible to combine both.

1.7.3 Arrangement of vowel alphabet elements in Thai vowels and subsequent control

In Thai, a vowel consists of several alphabetic elements and can come in the positions of the consonants up, down, left, right, left + right. In addition, if the shape of the vowel changes according to the support is not 100% regular, processing by the automata becomes difficult. Thus, we can think of processing the vowel alphabet elements separately.

There are about 20 different forms of Thai vowels classified according to their form (alphabetic element). By extracting the representative alphabet element from Thai and using the modified alphabet control button and the subsequent control button based on this, the extracted alphabet element can be regarded as an alphabet in another language.

Listing the types of vowel alphabet elements based on Unicode is as follows. This is a result of grouping two to three in consideration of the shape. All alphabetic elements are placed or grouped appropriately to select a representative alphabet element and require "modified alphabet control process" or "follow-up control process". You can place two vowel alphabet elements on each button, or one. When arranged one by one, considering the frequency of use, the first alphabetic element can be used as a representative element. Alphabetical elements not displayed on the keypad are handled by the control buttons.

1.7.4 Distinct Numeric Number Processing in Thai

Thai has unique numbers from 1 to 9. The input of the nine unique numbers can be selected before the number is selected after all the alphabets assigned to each button are selected when the repeated selection method is applied. It implicitly assumes that a unique number is placed on each button.

1.7.5 Arrangement of Consonants and Vowel Alphabet Elements in Thai

When configuring the form of a keypad (referred to as "reference keypad" for convenience) applying the concept of the reference lattice (not necessarily in the form of a lattice), and evenly representing consonants and vowel alphabet elements [1] The example of arrangement | positioning at the time of distribution to a]-[0] button is as follows.

First, in the case of arranging the representative consonants representing 21 sounds to 10 buttons [1] to [0], the 10 representative consonants representing each button group are arranged at the position of the reference grid. In Thai, "consonants + vowels" are repeated, so as to minimize ambiguity, the next 10 representative vowel alphabet elements, the remaining representative consonants, and the remaining vowel alphabet elements are arranged from a grid close to the reference grid. That is, consonants-vowel alphabet elements-consonants-vowel alphabet elements (abbreviated as "ja-mo-ja-mo") are arranged alternately from the reference grid in the order close to the reference grid. Or, it can be arranged in the order of "child-child-mo-mo" simply to increase the identification. If only one vowel alphabet element is placed on the button for each group, the last vowel alphabet element is not placed.

In the keypad dedicated to the repetition selection method, which is referred to as the "simple keypad" for convenience, it is necessary to arrange the "child-child-child" in order. Similarly, a "child-child" order is possible.

The 3x2 grid or the 2x2 grid (the space in which the alphabet is arranged) can be used as the form of the button of the reference keypad. 8-1 shows an example in which an alphabet is displayed on a 2x2 grid and a reference keypad is configured in the order of "child-child-mo-mo". 8-2 shows an example in which an alphabet is displayed on a 3x1 grid and a simple keypad is configured in the order of "child-child-child".

When all consonant and vowel alphabet elements are placed on the keypad, a three-by-two grid can be used because six alphabets must be placed on each button. When the reference keypad is configured, the reference keypad may be arranged in the order of "child-child-mo-child-child-child" or "child-child-mo-child-child-child".
