Description

Alphabet input device and method in small keypad {Alphabet input device and method in keypad}

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.

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 alphabet of each language greatly exceeds the number of twelve keys included in the keypad. 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.

The contents of Applicant's earlier application 10-2001-0000878 and other prior applications are supplemented.

Figure 2. Russian case

In summary, the invention as presented in the applicant's prior application (Application Nos. 10-2000-0031879 and PCT / KR00 / 00601,...) Is as follows.

First, according to the "partial full selection method", a predetermined number of grids are formed in a form corresponding to the arrangement of all buttons in the keypad to each button on the keypad, and the alphabets are arranged on the grids, and the alphabet to be input (hereinafter referred to as "target alphabet"). By pressing a combination of the first button and the second button on the keypad corresponding to the arrangement position of the alphabet in the grids of the first button, abbreviated as ", " For example, in Figure 1-1, A = [1] + [2].

Among the grids of buttons, some grids are used, including the reference grid where the first and second buttons are the same, and some grids are used, but the convenience of the combination of the first and second buttons is high. Using a grid of orders first was the key to the partial partial selection method. The core of the partial partial selection method lies in the reference grid, and the keypad that can utilize the concept of the reference grid is named "reference keypad."

Next, the standard repeat selection method is the number of pushes of the buttons in the order of close proximity to the reference grid from the alphabet of the reference grid position on the reference keypad configured to apply the partial full selection method. According to the method was to select the alphabet. The standard repetition selection method is to apply the repetitive selection method to the standard keypad. The dedicated keypad selection method is named "simple keypad". For convenience, the repetitive selection method is applied to the simple keypad as conventionally used. This is called the simple repetition selection method.

There was a "control processing method", which included "subscript control method" and "following control method". The subscript control method was a method of inputting a modified alphabet by combining a subscripted control and a basic alphabet when inputting a modified alphabet consisting of a subscript and a basic alphabet. Subsequent control processing method sets a group of alphabets assigned to a button in the relation between the representative alphabet and the subsequent alphabet, and inputs the subsequent alphabet by combining the representative alphabet and the sub-orders attached to the representative alphabet when entering the subsequent alphabet. It was to be. For example, in FIG. 4-1, it can be entered as "ㅋ = ㄱ + [*]".

Subscript control and subsequent alphabet control processing are essentially similar and subsequent control processing is considered more general. In the case of subscript control processing, it is considered that the modified alphabet is attached to the basic alphabet in a certain alphabetic group in a certain order. In the case of the superscript control process, since the modified alphabet can be decomposed into the subscript and the basic alphabet, the alphabet group has a strong association in its shape, and the subsequent control has a strong association in the order or pronunciation. to be.

The advantage of applying the control treatment method is that it is possible to simplify the arrangement of the keypad by not displaying the subsequent alphabet (or modified alphabet) on the keypad through the relationship between the basic alphabet and the subsequent alphabet (or modified alphabet). The control process allowed the alphabets to be entered without ambiguity. The simplified keypad, excluding the subsequent alphabet, was referred to as "sequence keypad." The simplified keypad, excluding the modified alphabet, was called "simplified keypad." Keypads displaying all subsequent alphabets (or modified alphabets) were referred to as "full display pads" in contrast to simplified keypads.

In the whole display pad, it is possible to input subsequent alphabets (or modified alphabets) through the control method. On the contrary, in the simplified keypad, the user who remembers the layout of the whole display pad can use the input method in the whole display pad. . Thus, the simplified keypad can be extended to configure the entire display pad, and the compatibility of being able to input subsequent alphabets through the control processing method according to the user's convenience was one of the characteristics of the previous application.

One of the effects of applying the control treatment method is, in addition to the effect of eliminating ambiguity, by "hiding" the subsequent alphabets without displaying them on the keypad through the relationship between the representative alphabets and the subsequent alphabets, as shown in the earlier application, The keypad can be simplified. This is called "hidden control method" for convenience. However, as mentioned in the earlier application, subsequent alphanumeric characters (or modified alphanumeric characters) may also be entered through the control method in the entire display pad where the keypad is displayed. This is called "non-hidden control method" for convenience.

The present invention proposes an improvement on the extension of the applicant's prior application (Application Nos. 10-2000-0031879 and PCT / KR00 / 00601). Since it is essential to give a specific example in view of the characteristics of the present invention, the details will be described through the embodiment.

First, the contents of the application for each language are supplemented as follows. It is obvious that any of the contents mentioned in any one of the following languages can be applied to other languages without being specifically mentioned in other languages.

1. Supplement

1.1 Japanese

In Japanese input, the method of inputting long sound, turbid sound, and half-track sound while using the grouping of 50 grams as it is and separating the subsequent control buttons is presented.

1.1.1 Cross Control Method (Zig Zag Control Method)

In inputting Japanese at the first application, the control button is repeatedly used (ie, the control is selected by the repetitive selection method), followed by the subsequent alphabet (2nd, 3rd, 4th, 5th alphabet) and the modified alphabet (long sound) , Sound, and half sound). However, in case of using [*] button (2nd, 3rd) and [#] button (4th, 5th) as a follow-up control button, to use [0] button as a control button for input of long sound, turbid sound, and halftone sound , The last letter of the 50-tone alphabet, "ん", is assigned to the [0] button, or to any of the [1]-[9] buttons, and the remaining alphabet is divided into nine groups [1] To [9] button.

However, in Japanese it would be natural to group the alphabet into 10 groups of 50 notes. In this case, as in the previous application, any of the [*] or [#] buttons is used as a follow-up control button for 2nd, 3rd, 4th, and 5th follow-up alphabet input. It can be used as the modified alphabet control button.

In the present invention, the alphabet is grouped into 10 groups of 50 pitches, and the subsequent controls are separated into the [*] button (2nd and 3rd controls) and the [#] button (4nd and 5rd controls), all within the 3 * 4 keypad. Provides a way to enter the Japanese alphabet. The following table shows an example of grouping the Japanese alphabet into groups of 50 phonograms.

Method of election Simple use of 50 notes Standard grid 2 ^nd 3rd 4th 5th Standard grid 2 ^nd 3rd 4th 5th あ い う え お あ い う え お か き く け こ か き く け こ さ し す せ そ さ し す せ そ た ち つ て と た ち つ て と な に ぬ ね の な に ぬ ね の は Hi ふ へ ほ は Hi ふ へ ほ ま み む め も ま み む め も や Yu よ や Yu よ ら り る れ ろ ら り る れ ろ W を ん W を

As described in the earlier application, the following groups may be arbitrarily assigned to each button. Figure 1 is an example of assigning alphabets of "A" column in alphabetical order to each button according to the following table. In the case of the previous application, the 4nd and 5rd controls could be additionally assigned to the control buttons assigned to the 2nd and 3rd controls, but here, only the 2nd and 3rd controls are assigned to minimize input strokes and make the most of the control buttons.

The method of inputting the subsequent alphabet in FIG. 1 is as shown in the previous application. For example, after control input, い = あ + [*]. Next, the method of inputting the alphabet, long sound, half sound, and half sound sound of each alphabet. In FIG. 1, all of the buttons ([*] button, [#] button) available as control buttons are used as subsequent control buttons. Therefore, there is no control button for the modified alphabet. However, if the basic alphabet of the target alphabet is the subsequent alphabet, the subsequent control button which is not used as the subsequent control button after inputting the subsequent alphabet can be used as a modified alphabet control button (referred to as "the opposite control button" for convenience). .

For example, ぃ = い + "opposite control buttons" = あ + [*] + [#], ご = こ + "opposite control buttons" = か + [#] + [#] + [*] . This is regarded as a modified alphabet of the basic alphabet i, and in applying the control method, it can be seen that the opposite control button which is not used as a subsequent control button for inputting a is used as a modified alphabet control button. As in the example, the skip control method of the previous application can be applied here as well. From the point of view of the chain control processing method, by pressing the control button across once, it is regarded as selecting the "next control" for inputting the alphabet (변형 in the example) of the input alphabet (알파벳 in the example). Can be.

There are two variations of the alphabet on the line, 탁 and 음, so in the case of long sound, press the opposite control button once, and in the case of halftone sound, press the opposite control twice.ぶ = ふ + "crossing control button" = は + [*] + [*] + [#], ぷ = ふ + "pressing two control buttons" = は + [*] + [*] + [# ] + [#]

Next, if the basic alphabet of the target alphabet is a representative alphabet, the above method cannot be applied as it is. In this case, in addition to any button of the subsequent control button, the modified alphabet of the representative alphabet may be placed as a subsequent alphabet to input the target alphabet.

For example, if you use the [*] button to enter a variation of the representative alphabet (long sound, sound sound, half sound), you will get あ = あ + [*] + [*] + [*]. In other words, the modified alphabets of the representative alphabets (long sound, sound sound, and half sound) are regarded as 4th successive alphabets that can be input by using the [*] button. The above is summarized as follows.

[*] Button [#] Button Use any of the [*] or [#] buttons (ex. [*] Button) Representative Alphabet 2 ^nd 3 ^rd 4 ^th 5 ^th 4 ^th 5 ^th 6 ^th 7 ^th . . . . . . あ い う え お ぁ number Young 1 (.) English 2 (Q) Zero 3 (Z) Symbol 1 . . . ぃ ぅ ぇ ぉ Utilize the opposite control button か き く け こ が number Young 1 Young 2 Young 3 Symbol 1 . . . ぎ ぐ げ ご Utilize the opposite control button . . . は Hi ふ へ ほ ば ぱ number Young 1 Young 2 Young 3 . . . び ぶ べ ぼ Utilize the opposite control button ぴ ぷ ぺ ぽ Utilize the opposite control button ...

Using the opposite control buttons to expand the use of the control buttons and to utilize more alphabets or other inputs is called "cross control processing" or "zigzag control processing" for convenience.

In the above table, it is obvious that the cells of the remaining columns except for the first column can also be used for inputting other alphabets or various symbols. In the example above, the control button on the other side is applied once. In other words, when inputting ぷ, ぷ = ふ + "press the control button 2 times across" = は + [*] + [*] + [#] + [#] repeatedly, and use it as a subsequent control button. The control button ([#] button) on the other side of the [*] button is applied only once. This is called "one-step cross-control processing" for convenience.

However, press 입력 = ふ + "press control button 1" + "press control button 1 for the previous control button" = は + [*] + [*] + [#] + [*] It may be. In other words, if it is not possible to input the modified alphabet by repeatedly using the control button ([#] button in the example) that was finally used to input ぶ, use the other control button again for the other control button in the same way. You can enter a variant or subsequent alphabet. This is called "two-step cross-control processing" for convenience. This means that the cross control method can be used to infinitely expand the number of possible inputs for the alphabetic or other alphabetic inputs that can be entered on the keypad. In addition, it is possible to naturally input subsequent alphabets or modified alphabets related to the pre-input alphabet by a control method.

In the application of the cross-control processing method above, an example of post-control input is shown, which is also input by control pre-input, just as control pre-input or post-input can be applied in applying the control processing method in an earlier application. You may. For example, ぃ = "opposite control buttons" + い = [#] + [*] + あ, but it would be convenient to enter the control afterwards when applying the crossover control method.

1.2 Russian

1.2.1 Composition of Russian

There are 33 alphabets in Russian. Ten of them are vowels, 22 are consonants and consist of one half vowel. Two of the 22 consonants are used as the sound and soft symbols.

1.2.2 Example of using a 3x2 grid of buttons [1] to [9]

Similar to the Korean case in the previous application, grouping the alphabet into groups of three to four, displays the first row of buttons ([1], [4], [7] buttons) and the third row of buttons ([3], [6] on the keypad. ] And [9] buttons) are assigned four alphabets using left and right combinations and up and down adjacent combinations. Three buttons are assigned to buttons in the second row in the center ([2], [5] and [8] buttons). You can assign an alphabet. In this way, 33 letters can be arranged in a balanced form on the 3 * 3 keypad ([1]-[9] buttons).

In grouping the alphabet three to four, it can be grouped in consideration of the order of the alphabet, frequency of use, pronunciation, etc. as in the prior application. The simplest way is to group them in alphabetical order as in the current English keypad. As presented in other languages in the previous application, it is possible to group in consideration of the similarity of pronunciation. The drawings are omitted.

1.2.3 Example of Entering Some Alphabets by Control Method

Some of the Russian alphabets have similarities in pronunciation and shape, or simply shape. For example, it can be seen that the half vowel "Й" has similarities in pronunciation and shape with the vowel "И". Some of these examples include:

1. For vowels and half vowels: И- Й

2. In the case of consonants and consonants 1: Ш- Щ-Ч- Ц

3. In the case of consonants and consonants 2: Б- В

4. For consonants and chord signs / beep signs: Б- Ъ- Ь, Б- Ъ, В- Ь. . .

5. For vowels and chords / sounds: Ы- Ь- Ъ, Ы- Ь,. . .

6. For vowels and vowels: Е-Ё

7. For consonants and vowels: З (consonants)-Э (vowels)

In the Russian configuration, the basic alphabet is put in ten basic vowels and 20 basic consonants, grouped three into two consonants and one vowel, and assigned to ten buttons [1] to [0]. As suggested in, the representative consonants of each group can be used for various memorization purposes or to compose simple codes.

In the first case above, the similarity in pronunciation and shape is apparent due to the relationship between vowels and half vowels, so it would be very natural to input them by the modified alphabet control method presented in the previous application. On the other hand, in the seventh case, the relationship between consonants and vowels, and the similarity in pronunciation, is considered unnatural. In the eighth case, since both are vowels and the similarity in pronunciation and shape is strong, the control method can be naturally applied by placing them in the relationship between the basic alphabet and the modified alphabet. However, the present embodiment does not apply this case in order to put ten vowels on each button.

In the second case, there is a strong similarity in shape and pronunciation, so we can have a relationship between the basic alphabet and the modified alphabet. In the third case, all four alphabets are consonants and have similarities in pronunciation and shape. Thus, Ш- Щ, Ц- Щ, Ч- Ц,. . . For six cases, there can be a relationship between the basic alphabet and the modified alphabet. In this case, the same modified (following) alphabet may be placed for different basic alphabets. For example, it is possible to put "Ш- Щ" in the relation of "basic alphabet-modified (following) alphabet", while at the same time Ц- Щ in relation of "basic alphabet-modified (followed) alphabet". Alternatively, the relation "Ц- Ш-Щ" may be regarded as "basic alphabet-2nd follow-up alphabet-3rd follow-up alphabet".

Next, the fourth case also has a similarity in shape as the relation between consonants and soft consonants / hard consonants. Therefore, the control method can be applied by placing an arbitrary alphabet in relation to the basic alphabet and the modified alphabet. In this case, there may be various methods as in the above example. For example, any alphabet of Б --- Ь may be used as a basic alphabet, and the remaining alphabet may be placed in subsequent alphabets (2nd, 3rd), or only a consonant code may be placed in a subsequent alphabet, such as Б-Ъ. The fifth case is a variant alphabet of vowel Ы with soft consonant / hard consonant signs. Similarly, both soft and hard consonants may be placed in subsequent alphabets or only one of them may be modified (followed) alphabets.

In the following example, the independent consonant 경 and the soft consonant and the soft consonant Ь are considered as variants of the consonant Б and vowel Ы, respectively, and the half vowel Й as the variants (following) alphabet of the vowel И. In this example, the remaining 20 consonants are grouped into 10 groups of 2 each in consideration of the similarity of pronunciation. The vowel Ы, like the soft consonant code Ь, is said to indicate that the preceding consonant is a soft consonant. As described above, both the soft consonant and the hard consonant codes may be put in a modified alphabet of the consonant Б (or vowel Ы).

БВ / ГК / ДТ / ЖЗ / ЛР / МН / ПФ / СХ / ЦЧ / ШЩ /

The above grouping is just an example and various groupings are possible in consideration of pronunciation. Based on the above grouping, an arbitrary alphabet may be designated as a representative alphabet in consideration of a dictionary order or frequency of use. 10 vowels can be grouped one by one.

Fig. 2 shows an arbitrary alphabet of the above consonants as a representative alphabet of each group, placed at the position of the reference lattice, the vowels placed on the lattice close to the reference lattice, and the remaining consonants on the lattice close to the reference lattice. This is an example. In some cases, of course, the vowels can be placed on the reference grid with the representative alphabet and the consonants on the rest of the grid.

When applying the partial partial selection method in FIG. 2, Б = [1] + [1], А = [1] + [2], and В = [1] + [3]. When applying the standard repetition selection method, Б = [1], А = [1] + [1], В = [1] + [1] + [1]. Select the alphabet placed on the keypad as the standard repetition selection method, use the [*] button as the modified alphabet control button, and apply half-width Й by applying the input after control. Й = И + {Transformation} = [4] + [5] + [*]. In the same case, the hard sign 부호 = Б + {variation} = [1] + [1] + [*]. If the soft consonant sign Ь is regarded as a subsequent alphabet of Ъ, then Ь = [1] + [1] + [*] + [*]. The same applies to the case where soft consonant codes and hard consonant codes are regarded as variants of the vowel Ы.

The keypad can be used to easily enter the alphabet.
