Abstract

PURPOSE:To efficiently input Chinese by using a keyboard provided with plural sound keys arranged symmetric to two shift keys and fully utilizing the shift keys. CONSTITUTION:The keyboard is divided into left- and right-hand parts. If the wound key is individually keyed in, a pin-in stated at the lower part on the sound key can be inputted. For inputting a pin-in at the upper part of the sound key, it can be inputted if the shift key at the side the same as the inputted pin-in is simultaneously keyed. For inputting a light sound part, the shift key on the side opposite to the sound key to be keyed in is simultaneously keyed in. In terms of sound groups on the keyboard, a chinese phonetic alphabet part and a double consonant part are symmetrically arrayed on the left- and right-hand parts, respectively. The consonant part is arranged in a way similar to the order of (b), (p), (m), (f), (d), (t), (n), I.... For inputting the consonant part, a consonant and semivowel obtained by adding a semivowel (i) or (u) to the initials stated at the lower part are inputted when the sound key and the shift key are simultaneously keyed in.

Description

[Detailed Description of the Invention] [Summary] In the Chinese character-sound two-touch input method, a keyboard having two thumb shift keys and a plurality of symmetrically arranged character-sound keys is used, and the thumb shift keys are utilized. In addition to shoji, yohei, upper voice, and kyosei, the tone input can be changed to
It is also possible to input weight and weight.

[Industrial application field]

The present invention is a two-touch Chinese input method that inputs Chinese character sounds by dividing them into voice-interposed compound sounds and details, which has two thumb shift keys and a plurality of symmetrically arranged character sound keys. Using the keyboard, it is possible to input tones such as shoji, yohei, upper voice, kyosei, and light and heavy.

[Prior art and problems]

Zion is the reading of kanji. Chinese characters are made up of ``accents''. The sound of each kanji is fixed. Japanese characters are only syllables. Accent is added only after the word is formed. For example, in the case of "draft", an accent is added when the word becomes "guidance" or "unexpected", with the former in an ascending tone and the latter in a descending tone. As shown in FIG. 7, a letter is composed of a syllable and a tone, a syllable final and a final, and a final is composed of a rhyme part, a rheme part, and a rheme part. Japanese) is a variation of the human voice in Chinese. Examples of Chinese character sounds and Japanese character sounds are shown in Figure 8 fa+, (bl).

Pinyin is a phonetic alphabet created to represent Chinese characters back in the day. On February 11, 1958, China's National People's Congress ratified the Chinese Pinyin Plan, and since then China has put great effort into popularizing Pinyin. Pinyin uses Mandarin as the standard sound, uses the alphabet, and represents syllables in the form of phoneme combinations (initial + initial + rhyme + rhyme). In the "Chinese Pinyin Scheme", there are 21 initials, 3
8 finals (35 finals - 1.e, er) 1
Four tone codes are defined.

There are four tones: shoji, yohei, josei, and gyosei, and they are also called 1, 2, 3, and 4 tones.

In this specification, they will be expressed as 1, 2, and 3.4, respectively. FIG. 9 shows 21 finals, and FIG. 10 shows 35 finals.

There are over 400 syllables in Chinese. If you add tones to these syllables, there are 1,300 Chinese character sounds.

If you try to input a letter sound with one touch, it will take about 1300 characters.
Requires several input keys. There will be no way to reduce this number of input keys other than by pressing two keys at the same time. When inputting a letter sound with two touches, you must first think about how to divide the letter sound into two elements. If we break down the letter sounds into the smallest units, we get the formula a.

Letter sound - initial + initial + rhyme + rhyme + tone...a The most natural form is probably the 5th type.

Letter sound - final tone + (head + rhyme part + rhyme part ten tones)...b However, in this case, the number of "final ten tones" which is the second element of the letter sound is 38 (final) x 4 (tone) = 152 become. Since the first element is around 21, this is an imbalance.

Traditional Chinese input methods break down syllables into initials and finals,
I was inputting with two touches, and I was not inputting the tone.

In this conventional method, multiple kanji are displayed on the display for the input syllable, and the user must select the desired kanji from among them, so the input operation is not efficient.

[Purpose of the invention]

The present invention is based on the above considerations, and aims to provide an input method that allows efficient input of Chinese characters.

[Means to achieve the purpose]

Therefore, the Chinese input method of the present invention uses a keyboard,
Equipped with a control unit having a letter sound flag and a display,
The keyboard has a plurality of letter sound keys, a left shift key, a right shift key, and a conversion key arranged substantially symmetrically, and the control unit is configured to control when only the letter sound key is pressed when the letter sound flag is in a predetermined state. In this case, it is recognized that the first vocal combination assigned to the character-sound key has been input, and the character-sound flag and the shift key on the same side as the character-sound key are pressed while the character-sound flag is in a predetermined state. recognizes that the second vocal compound assigned to the letter-sound key has been input, and if the letter-sound flag is set under other predetermined conditions and only the left letter-sound key is pressed, the letter-sound key is It is recognized that the rhyme part and the first type of tone assigned to are input, and if the character sound flag on the left side and the left shift key are pressed under other predetermined conditions, the character sound flag is set to the corresponding character sound key. It is recognized that the assigned rhyme part and the second type of tone have been input, and the letter sound flag indicates the details assigned to the letter sound key if only the right letter key is pressed under other predetermined conditions. and the third type of tone have been input, and if the letter sound flag and the right shift key are pressed under other predetermined conditions, the letter sound flag is set to the rhyme part assigned to the letter sound key. It is recognized that the fourth type of tone has been input, and if the above-mentioned character sound flag is pressed under other predetermined conditions and the shift key on the opposite side of the character sound key is pressed, the tone part and weight assigned to the character sound key are After recognizing that a tone of voice has been input and storing recognition result information corresponding to the pressed letter sound key in a predetermined storage area,
The state of the character-sound flag is switched, the recognition result information is displayed on the display, and when the conversion key is pressed, the kanji corresponding to the recognition result information displayed on the display is displayed, and the character-sound flag is displayed. The device is characterized in that it is configured to bring the device into a predetermined state.

[Embodiments of the invention]

The present invention will be explained in detail below. In the present invention, a character sound is input after being decomposed into the following: character sound - (voice final ten tone final) + (B belly + rhyme part ten tone). This is called type 0. (Voice initial + rhyme initial) is called a voice-mediated compound, and (rhyme part 10 rhyme part) is called a rhyme part.

There are three details: i, u, and v. As shown in Fig. 1, there are 53 elements in the vocal compound.

Regarding the spelling of i, u, ν when there is no initial, and V when the initial is J + Q + X, "Chinese Pinyin method"
contains the following notes:

・Syllables whose initials are i or whose initials are i are expressed as y ten rhyme part + rhyme part.

That is, syllable 111a11elloII+ 1aO+
1an+ in, iang+ Ing, iong, respectively, V1+ya+Ve+yOu+VaO, yan
, yin.

Write yang + ying + yong.

・Syllables that have no initial and whose final is V or the beginning of the final is V are expressed in the form of y ten final by replacing V with U. That is, syllables y, y6. van, vn, respectively
Write it as u+ Vue+ Yuan+ yun.

- Syllables whose initials are J+Q+X and whose finals are V or whose initials are V are expressed by replacing V with U.

For example, the syllables jv, jve, jvan, jvn are respectively written as JLj Ue+ J LIan+ J un
・Considering the above precautions, rewrite kodo i, u, and v to y and yl+W+VII, respectively, and write y, tm
is regarded as the mother of voices. Also, jv, qv, and xv are rewritten to ju, qu, and xu, respectively.

The rhyme part consists of the following 16 pieces. If this is combined with the four tones (Shoji, Yohei, Josei, and Gosei), the second element becomes 64.

i u v a o e at ei
ao ou an(e) n ang (e
) ng ong erin, ing is not added to the rhyme section. Looking at the rhyme final table of the "Chinese Pinyin Plan", in is the rhyme part en with the initial i added before it, and originally ten.
It is interpreted that what used to be ``in'' has been changed to ``in'' by omitting the e. The same applies to ing, and here it is assumed that ieng has become ing.

In the table of 16 rhymes above, (e) n, (e
) ng indicates that e can be omitted. syllable y
The input of ing is yi+ (e) ng+ and the input of jun is ju+ (e) n.

According to formula 0, 54 first elements consisting of voice-interposed compound and ``
64 second elements consisting of "n-part child tone" were obtained. If you use the shift key when typing, you can halve the number of keys for both.

For the first element, the input key is set as shown in Figure 2 (ta). In Figure 2+a), j(i) means both j and i. The only details that can be combined with j are j and ν. Also, the two parts i and ν are never combined with ji. Therefore, even if the common keys j and ji are made the same key, the number of duplicate codes will never increase.

The same applies to q(i), x(1), and y(i).

For the second element, two sets of 16 input keys as shown in FIG. 2(b) are set, and are labeled as a flat key and a rhyme key, respectively. If you press the flat rhyme key and the shift key at the same time, 1
Suppose that a voice is input, and if you type it alone, two voices will be input.

If the rhyme part key is pressed at the same time as the shift key, three voices will be input, and if it is pressed alone, four voices will be input.

The words used in this specification, such as zaben joint mother, detail, and plain, are not original to us. When teaching Binyin, there is a teaching method called ``Zaben Gaibou Method''. This method was used in Chinese elementary school Japanese language classes for about 10 years starting in 1963.

The characteristic of this "zaben gomo method" is that the initial and the rhyme part (diacritic) are put together and this is called zaben gomo, and the syllable is 1 zaben gomo + (
The point is that it is broken down into ``rhyme + details)''. In addition, 197
From the 2000s, the ``three-pin continuous method'' was adopted in place of the ``zaben joint method,'' but this changed the syllables to ``voice initial + rhyme part → - (rhyme part + rhyme part +
In terms of input methods, there are 3
That's over a thousand cods.

Let me explain the details and plainness using Chinese poetry as an example.

Zhang 111 ``Night Night on the Maple Bridge'' Chinese poetry has rules for plainness and rhyme. In the case of the above jōshu zekku, the plain and rhyming must follow the following rules.

（平） 仄平平平（组） 仄平き（
平） 平（仄） 仄 组 平 平.

(平) 平 (仄) 仄 平 平 仄(仄) 仄 平平 (仄) 仄 平木 There were four types of tones in ancient Chinese: womb, upper voice, left voice, and human voice. ``平'' in 平组 means a thousand voices, and ``廄'' means tones other than the womb, such as the upper voice, the lower voice, and the human voice. The tones of modern Chinese are the result of the ancient womb being differentiated into Yangping and Yangping, and the ancient human voice disappearing and changing to other tones. Therefore, ``hira'' means yōhei (one tone) and yōhei (two tones), and ``组'' means upper tone (three tones) and left tone (four tones).

The character with the ``leaf'' must have the same rhyme as the character with the ``rhyme'' (rhyme). This is rhyme. The important thing to remember here is that the rhyme does not match the final word, but the details. .In the example above, it is “heaven”.

``Sleep'' and ``ship'' are rhyming characters, and what is required here is not to make the rhyming finals fan, tan, and uan the same, but to match the details of the character ``leaf'' to the details of the character ``rflJ.'' It is to match an.

Now, the first element, which has been separate until now, is the zabengomo (
Let's consider a method of combining the input key of the second element, that is, the input key of the flat rhyme part or the syllable part (hereinafter abbreviated as tone), into a letter sound key. Here, we will introduce the anti-cut method.

The anti-cutting method is a method that has been used since ancient times in China. This method uses two Kanji characters that can be read by ordinary people to represent the sounds of difficult characters.

Let me give you an example.

蓼(liao3): Satoshi (1i3 xioa3)
) Separation (gou4): Dried meat (ganl rou
4) Kirihama (bangl): Roppo (bal f)
angl) To explain with the example of "蓼", the difficult to read character "蓼"
The sound of the letter is expressed in two characters that everyone can read: ``ri'' and ``小''. The first character representing a character sound ("ri" in the example) is called an anti-kiri upper character, and the second character representing a character sound ("ko" in the example) is called an anti-kiri lower character. The character "kiri" after an anti-kiri-shita character indicates that the two characters before it (in the example, "riko") are anti-kiri characters (kanji that represent character sounds according to the anti-kiri method). Sometimes ``anti'' is used instead of ``kiri''. Also, the characters that used to be used as anti-kiri characters (for example, ``蓼'') are called hankoku-kiriji.The basic principle of anti-kiri method is , lower letter tori fi (taking the initial of the upper character and taking the final of the lower character). That is, in the anti-kiri method, the initial of the anti-kiri upper character (l in the example) and the finale of the anti-kiri lower character (in the example, 1ao3 tone is also included) are combined,
Represents the sound of a ripple-cut character (1iao in the example).

In the anti-cut method, one letter sound is always represented by two letters. For characters without a voiced mother, the character with a zero voiced mother is used in the anti-cut upper character.

The input method considered in the present invention also includes a zero-voice key,
It is specified that one letter sound must be input with two touches (letters with no final and only a vocal initial are excluded). Now, redistribution key x
Combining i with rhyme key ang1, letter sound key xiang
Suppose we created l.

Similarly, the subdivision key b and the fit [key ao3 are combined to create the letter sound key bao3.

Provide a letter sound flag. Assume that if the character sound key is pressed when the character sound flag is OFF, the first element of the character sound key, that is, the seat valve, is input. It is assumed that if the character sound key is pressed while the character sound flag is ON, the second element of the character sound key, that is, the cadence, is input. In the input method discussed in this specification, one character sound is always input with two touches, the first element and the second element, that is, the first element and the second element are always input alternately, so the character sound flag Simply switch ON and OFF alternately. The initial state of the character sound flag is set to OFF.

For example, when inputting the character sound for "small" (xiao), if you first press the xiangl key when the character sound flag is OFF, it will be recognized that the seat valve xi of the xiangl key has been input, and xi will be displayed on the display. . By this touch, the letter sound flag automatically switches to ON, and then ba
When the 03 key is pressed, it is recognized that the rhyme ao3 of the bao3 key has been input, and ao3 is displayed on the display. In this way, the character sound xiao3 is input with two touches of the xiangl key and the bao3 key. If the character sound flag is turned OFF again and you want to input the character sound (bangl) for 'hama', you can input bangl by pressing the bao3 key and the xiangl key in succession.

Taking the basic principle of the anti-cut method as a hint, the input method of the present invention is ``first key take the seat valve, back key take tone (when the letter sound flag is OFF, take the seat valve of the input key, and the letter sound flag is ON. (takes the cadence of the key entered when .).

As can be seen from the above example, if a letter sound flag is provided, the two elements of the letter sound (seated dialect and cadence) that are decomposed according to formula 0 can be
You can combine them again and combine them into letter-sound keys.

It is enough to have 32 letter-sound keys.

Next, a Chinese two-touch input keyboard consisting of 32 character-sound keys will be explained. As mentioned above, when inputting a character sound (kanji) using this keyboard, the user is instructed to input each character sound with two touches, one for the accent and the other for the tone. Adhering to this principle, the user searches the keyboard's letter and sound keys for the key that has the desired zaben or cadence written on it, and when the user presses the key, the zaben or cadence is displayed on the display. Also, if you press the conversion key, the character sounds displayed on the display will be converted to kanji.

An example of this keyboard is divided into a left half and a right half, as shown in FIG. 3(a). By hitting the letter sound key alone, you can input the pinyin written on the bottom of the letter sound key. If you want to input pinyin on the upper side of the letter-sound key, you can do so by pressing the shift key on the same side as the pinyin you want to input (left shift key if it's on the left hand, right shift key if it's on the right hand) at the same time.

If you want to input a light and double rhyme part, press the shift key on the opposite side of the letter sound key you are typing (if the rhyme part is on the left hand, press the right shift key,
If it's on your right hand, press the left shift key at the same time. Figure 3 (The melody of the al keyboard is symmetrically arranged with the flat part on the left hand and the melody part on the right hand.The seat valves are b,'
p, m, f, d, t, n.

If you press the letter key at the same time as the shift key when inputting the seat valve, the vowel will be placed in the same order as the initials (voice vowel), which is written at the bottom. Department)
The seat valve plus i or U is input.

However, separate keys are provided for du, tu, nu, and Iu. If you keep the above in mind, you can omit the display of letter and sound keys as follows. FIG. 3(b) shows an example of a simplified Chinese 2-touch keyboard. In Figure 3(b),
The seat valve is represented by a capital letter, and the melody is represented by a lower case letter.

Note that the left shift key and right shift key are omitted in FIG.

Note that the fact that a light and heavy cadence is input when the character sound key and the opposite shift key are pressed at the same time while the character sound flag is ON is omitted in FIG.

〔Effect of the invention〕

The input method discussed in this specification enables two-touch input of character sounds by breaking down character sounds into two elements, syllable and cadence, and incorporating the concept of anti-dissection.

By pressing the 32 character sound keys twice, the user can input all of the approximately 1,300 Chinese character sounds, and can also input weight and weight.

Up until now, the basic input method for reading Chinese has been to input syllables with two touches. When inputting Chinese readings, duplicate codes with same character sounds are a big problem.

Comparing the character input and the syllable input, it can be seen that there is a larger than expected difference in the number of homophones between the two.

A glyph is a syllable plus a tone. Tone is one of the major characteristics of the Chinese language, and is an essential element of the language. When inputting glyphs, the tone of voice must be input correctly. Therefore, the input method described in this specification also provides an opportunity for users who regularly use incorrect tone of voice to correct it. Alphabetical input is far less complex than conventional syllable input.

We hope that this input method will not only play a role in the field of Chinese information processing, but also contribute to the spread of Putonghua (standard language).
