It induces pronounciation code and tune code according to the Chinese Phonetic Alphabet, and induces radical-character body pronounciation code input method according to the pentype of Chinese characters, and inputs the phrases consist of 1, 2, 3 or more than 3 characters according to different rules. This can realize a combined input of the Chinese Phonetic Alphabet and the pen-type of the Chinese characters, and realize a combined input of various characters, such as Chinese characters, Arabic numerals, interpunction and English letter of alphabet etc..According to the present invention, the average code length is shot, the duplicate code rate is low and the efficiency is high, and the Chinese Phonetic Alphabet and the pen-type can be combined input. It's easy to learn and can be used easily. Under the situation of doing not switch the input state, various characters, such as Chinese characters, Arabic numerals, interpunction and English letter of alphabet etc., can be combined input.

Description

Character input method in word units

The present invention is a character input method, in particular, a method of inputting characters (including Chinese characters, Arabic numerals, punctuation marks, English letters, etc.) in units of words using a numeric keypad. Background technique

At present, there is a trend of laptop, palmtop, and miniaturization in computers. Mobile phones are gradually showing the trend of having various functions of computers, such as PDAs, set-top boxes, e-books, handheld terminals, household appliances, automotive electronics, ATMs, and bar code reading. Embedded devices such as devices, data collectors, game consoles, karaoke players, MP3 players, public information inquiry terminals, two-way pagers, and landline telephones are also urgently needed to input various information conveniently and quickly using numeric keys. It is required to convert the existing character input method mainly using English letter encoding into a character input method mainly using digital key encoding.

The Pinyin input method represented by smart ABC and Microsoft Pinyin is the mainstream input method for people to input Chinese characters on a PC. In order to improve the input efficiency of the Pinyin Chinese input method, the inventor invented the Pinyin hybrid input technology in 1995 according to the Chinese knowledge of the Chinese Pinyin Program and the Basic Rules of the Chinese Pinyin Orthography. (China Special Edition ZL 95102608. 9), effectively solves the contradiction between the easy-to-learn and the later efficiency of Chinese characters input, making the input of computer Chinese characters mainly using Chinese Pinyin coding faster and more convenient. In the invention, the concept of the tone code I and the tone code II is proposed. Convert zh, ch, sh, ng, U in Chinese Pinyin without tonal symbols into έ, c, s > , v, respectively, to form a compressed phonetic code; when the code length of the compressed pinyin code is 1, repeat the compression The pinyin code constitutes a pinyin code. When the code length of the compressed pinyin code is greater than 1, the compressed pinyin code is used to form the pinyin code; the first code of the pinyin code is defined as the tone code I, and the pinyin code other than the first code is determined as Code II.

However, in handheld, miniaturized computers as well as mobile phones, set-top boxes, e-books, handheld terminals, home appliances, automotive electronics, ATMs, bar code readers, data collectors, game consoles, karaoke 0K jukeboxes, MP3 players, In the field of embedded devices such as public information inquiry terminals, two-way pagers, and fixed telephones, the efficiency of Chinese character input is still relatively low. The application of Chinese characters in the mobile phone field is T9 of Tegic Communications, iTAP of Motorola, and the Chinese input method of eZiText of the Canadian word source (Z i ). The input method mainly uses the eight numeric keys 2, 3, 4, 5, 6, 7, 8, and 9 to input the word first and then add the association function. In, the efficiency is much lower than the Chinese character input method on the PC.

In these fields, the main reason why the main pinyin input methods are inputting Chinese characters in words is: If full code is used (no tone is used), the Chinese pinyin code length of any single word is 1 to 6 yards, double The words are 2-12 codes, and the three words are 3-18 codes... The code is long, ambiguous, and it is not convenient to input. If you use a short code, it will increase the number of syllables, which in turn will affect the input efficiency.

In addition, many users are not very good at mastering Chinese Pinyin. They tend to use pen to input Chinese characters. However, due to the characteristics of Chinese characters, many Chinese strokes are numerous, such as "Call" strokes up to 48 strokes. The stroke input method has a long average code, a large number of codes, and low efficiency.

In addition, whether it is Chinese or English and other language input systems, when inputting information such as Ala 白 white numbers, punctuation marks, English letters, etc., it is necessary to switch the input state, the keystroke efficiency is low, so that the tears feel extremely inconvenient.

The present invention is directed to the above problem, and a universal character input method based on words is designed, which solves the above problems skillfully, and particularly solves the problem of how to input Chinese characters in units of words. This method can be applied not only to Chinese input, but also to various language inputs such as English input, Japanese input, German input, French input, and Spanish input. Summary of the invention

The present invention has been made in view of the above problems in the prior art, and an object thereof is to provide a character that can quickly input characters by using a numeric keypad, and can input and input any character without switching the input state, in particular, can use the sound code. Or the method of quickly inputting Chinese characters by the radicals.

In order to achieve the above object, the present invention provides a character input method in units of words, which is characterized in that:

(Audio code, c, s, n are defined on the o and l keys respectively, and each key defines any two of them)

Enter the characters containing the Chinese characters as follows:

(1) The encoding of Chinese characters = the numeric key corresponding to the Chinese character's audio code I + the Chinese character's audio code Π; the numeric character's encoding is its own corresponding numeric key; the English alphabetic encoding is defined according to the above numeric keypad The numeric key; the encoding of the punctuation is the numeric key corresponding to the first code of the encoding corresponding to the pronunciation;

(2) If it is a word consisting of 1 character, its encoding is the encoding of the character, and the sequential keystrokes input the word;

(3) If it is a word consisting of 2 characters, use the code of the 2 characters that make up the word (before the N code of the N code, 1^ is a natural number of 1, if N<5, the coding space is small, Too many re-codes, the effect is not good, so it is recommended that N is generally greater than or equal to 5), and the word is entered by sequential keystrokes;

(4) If it is a word consisting of 3 characters, encode the first code + the last two characters of the first character (longer than the N code of the N code), and enter the word in sequence;

(5) If it is a word consisting of more than 3 characters, the code other than the first code encoded by the first code + the last character of all characters (longer than the N code of the N code), Enter the word by sequential keystrokes.

In addition, if it is a word consisting of 3 or more characters, the coded first code + the last character code of all characters except the first code (longer than the N code of the first N code) , type the key to enter the word.

In addition, define the tone code on the numeric keypad as follows:

Tone code tone tone

Yinping 1

2 Yangping 2

3 Up 3

4 go to sound 4

5 softly

5

When a word is composed of two or more characters whose last character is a Chinese character, and the code length of the word is less than N code, the tone code of the last Chinese character is added after the word is encoded, and the sequence key is pressed. Enter the word. In addition, if it is a word consisting of one Chinese character, the number key corresponding to the standard Chinese Pinyin of the Chinese character constituting the word may be used, and the word is sequentially input by the keystroke.

In addition, when the code 1 of the Chinese character is 2, c, S, zh, ch, sh can be used as the code of the code I; when there is n in the code II of the Chinese character, ng can be used instead of n The encoding of the Π code; the encoding of the kanji character = the numeric key corresponding to the encoding of the syllable code I of the Chinese character + the numeric key corresponding to the encoding of the timbre II of the kanji.

Further, the above-mentioned tone code 2, £ is defined on the key 1 and η is defined on the key 0.

In addition, if it is a word consisting of 2 or more characters, the code of all characters is encoded by the first code + the last character, except for the first code (before the weight of the weight) , / / keystrokes to enter the word.

In addition, for many users who do not have the problem of partial Chinese pinyin, the encoding of Chinese characters can also be encoded without the use of the following radical-character code input method:

(a) Take the radical set containing and including only the horizontal "one", the vertical "I", the 撇"j", the point ",", and the five single-head radicals, according to the horizontal 1, vertical 2, 撇 3 , point 4, fold 5 code, constitute its radical code;

The capital of each Chinese character is the first of the Chinese characters. If a Chinese character is one of the radicals in the determined radical set, or is composed of a variant of a radical, the encoding of the Chinese character is The radical code corresponding to the radical. Such as "one" 1, "B" 5 and so on.

If a Chinese character has only one stroke, the Chinese character is a Chinese character without words, such as "one", "B", etc. Otherwise, the Chinese character is a Chinese character with a font. For Chinese characters with characters, the part outside the radicals constitutes the body of the Chinese character. For example, the radical of the "person" is 撇, the body of the character is a point; the first code of the radical is taken, and the code of the body is taken. For example, the radical code of "person" is 3, and the font size is 5; the radical code plus the font code is the encoding of the Chinese character, and the specific coding order is consistent with the relative position of the radical and the font, but the most Long take the N code, that is, after the code is taken according to the rule, the part after the Nth code is omitted. The specific method of the font code is as follows: According to the writing order of the font body, the characters of the Chinese character are coded one by one according to the rules of horizontal 1, vertical 2, 撇 3, point 4, and folding 5, which constitute the character code of the Chinese character.

The above code is the canonical code. Any Chinese character has the form of a canonical code. Such as N=8 Bt "一" 1, "B" 5, "人" 34, "大" 134, "会" 341154, "construction" 12343554, "code" 13251551, "蠤" 41431251 and so on.

(b) If the font of a Chinese character is left and right, but the radical of the canonical code is not all parts of its left or right side, and all parts of the left or right side may constitute a Chinese character; or a Chinese character The font is of the upper and lower type, but the radical of the canonical code is not located on the upper or lower part of it, and all the upper or lower parts can constitute a Chinese character, and the Chinese character has a fault-tolerant code:

i. The above-mentioned part that can constitute a Chinese character is defined as a virtual radical, and the number corresponding to the sound code constitutes the virtual first code of the Chinese character. For example, "construction" takes "wood" as the virtual radical, and the virtual radical code is 68 (mu).

Ii. Define the part outside the virtual radical of the Chinese character as the virtual font. Encode the virtual font according to the following rules, and define the encoding result as the virtual font: (1) If the virtual font is composed of 1 part And the part is a radical or a Chinese character, and the radical code of the radical or the number corresponding to the Chinese character is formed, and the virtual character code of the font is formed; the body is both a radical and a It is a Chinese character, according to a radical processing. For example, "construction" takes "hook" as a virtual font, and the virtual font code is 468 (gou). (2) If the virtual font is composed of one part, and the part is neither a radical nor a Chinese character, first determine the code length of the first part of the Chinese virtual part, and then press the order of the virtual type Strokes are taken on the virtual character body one by one, and the difference between N and the code length of the virtual part of the Chinese character is taken up to form a virtual character code of the character body. For example, if the "city" virtual radical is "towel", the virtual radical code is 546, and the length is 3, the virtual font code is 41. (3) If the virtual font is two or more parts, each part is taken with a code to form the virtual character code of the Chinese character: the part constituting one radical takes the radical corresponding to the radical The first code of the code does not constitute a radical but the part constituting a Chinese character takes the first code of the number corresponding to the Chinese character code. In other cases, the radical code corresponding to the first stroke of the part is uniformly taken. For example, the virtual radical of "鑤" is "Dragon", the virtual character is composed of two "Dragons", and the virtual character code is 55 (11).

Iii. According to the "virtual radical code plus virtual character code is the encoding of the Chinese character, the specific coding order is consistent with the relative position of the virtual radical and the virtual font, but the rule of the longest N code" is combined with the Chinese character. The virtual part code of the virtual part and the virtual character code of the Chinese character constitute the fault-tolerant code of the Chinese character.

For example, when N=6, "construction" takes "wood" as the virtual radical, "hook" as the virtual font, and the fault-tolerant code is 68468 (mugou). Of course, you can also take "hook" as the virtual radical and "wood" as the virtual The word body has the same result; "code" takes "stone" as the virtual radical, "ma" as the virtual font, and the fault-tolerant code is 0462 (s ima), of course, you can also take "horse" as the virtual radical, "stone" For the virtual font, the result is the same; "such as "take" female is the virtual radical, "mouth" is the virtual font, the fault-tolerant code is 68,568 (nvkou), of course, you can also take "mouth" as the virtual radical, "female "For the virtual font, the result is the same; for example, "vertical" takes "立" as the virtual radical, and the part outside "立" is the virtual font, the fault-tolerant code is 225454 (2254Π); and the fault-tolerant code of "箩" is 54055 ("蠤" conforms to the definition of fault-tolerant code, with fault-tolerant code, that is, the number 540+ of the first "Dragon" of the virtual radical and the code of the virtual dragon "Dragon" 55), etc. The definition of the above-mentioned Chinese character specification code and fault-tolerant code fully exerts the potential of the 10 key positions on the numeric keypad. By combining the code of the mixed input word by the canonical code and the fault-tolerant code, the efficiency of the shape code input can be close to the pinyin mixed input of the keypad. The efficiency of technology.

In order to improve the easiness of the above-mentioned radical-character code input method, the present invention can improve the above-mentioned radical-character code input method (hereinafter referred to as improvement 1): stipulates the virtual character code in addition to the virtual font itself. It is a Chinese character that still takes the number corresponding to the Chinese character's code as the virtual character code of the Chinese character. In other cases, the law draws strokes on the virtual character to form the virtual character code of the Chinese character. This improvement simplifies the coding method of the virtual character code and improves the ease of learning of the input method of the radical character code. For example, the virtual part of "蠤" is "Dragon", and the virtual body is composed of two "Dragons". According to this improvement, when N=6, the virtual character code consists of the first three strokes (414) of the virtual form.

In order to further improve the ease of learning of the present invention, the present invention may also improve the above-mentioned method for inputting the radical-character code as follows (hereinafter referred to as the improvement 2): stipulate that in any case, the strokes of the virtual character are drawn one by one, forming Chinese characters. The virtual character code. This improvement further simplifies the coding method of the virtual character code, and makes the error-tolerant code reach the highest level. For example, if N=6, the code of "reason" is 112125 (canonical code), or 920251 (take "king" as virtual radical, "li" as virtual font, virtual part first code is 920, virtual font code is "" "The first three digits correspond to the digital code 251", or 112154 (take "Li" as the virtual radical, "Wang" as the virtual font, the virtual radical code is 54, and the virtual font code is "Wang" the first four strokes Corresponding digital code 1121), and so on.

In the above coding rules, many Chinese characters have both a canonical code and a fault-tolerant code. Therefore, there are many possible combinations of word coding, which occupy a large memory space, and some embedded devices have certain difficulty in implementation. For this reason, the above-described radical-character code input method and its improvement method can be further improved (hereinafter referred to as improvement 3): only the last Chinese character of the word allows the use of the fault-tolerant code. For example, if N=6, the code of "computer" is 431234 ("the machine" specification code), or 436854 ("machine" error-tolerant code, nrnj i), and so on.

In addition, the above improvements can be further improved (hereinafter referred to as Improvement 4): Any Chinese character is encoded using only the canonical code, and no fault-tolerant code is used under any circumstances. For example, when N 6 is "computer", the code is 431234, and so on.

Further, the above-described improvement 4 can be further improved (hereinafter referred to as improvement 5): a word composed of two or more kanji characters, when its code length is less than N code, is complemented by 0 after its coding. For example, if N=6, the full code of "one by one" is 110, so that no double code is generated with the full code 11 of "two", which effectively reduces the word composed of one Chinese character and the word composed of two or more Chinese characters. The possibility that the full code of the word has a re-code. In addition, the above method can be further improved (hereinafter referred to as improvement 6): a word consisting of one Chinese character can be compatible with the error-tolerant code encoding using Chinese characters. For example, if N=6, the code of "machine" is 123435 (canonical code), or 6854 (fault-tolerant code, muji), which speeds up the input speed of a word composed of one Chinese character.

In addition, in order to further improve the efficiency of word input composed of one Chinese character, the present invention can also improve the above method (hereinafter referred to as improvement 7): in the input process, the word composed of one Chinese character is compatible. Audio code and standard Chinese Pinyin input. That is, any word consisting of one Chinese character can be input according to the above method, or the Chinese character of the word, or its standard Chinese pinyin input. This solves the problem that some users are unclear about the stroke order of some Chinese characters and difficult to input. In the specific implementation, you can choose to be compatible with only standard Chinese Pinyin, or you can choose only compatible audio code, or you can choose to be compatible at the same time. This actually implements a shape-compatible input.

The above improvements can be further improved by itself. For example, it can be specified that: Chinese characters in words consisting of two or more characters, if there are both a normal code and a fault-tolerant code, only a fault-tolerant code is used, and a normal code is not used. This can effectively reduce the number of words encoded and facilitate the application of embedded systems.

The above-mentioned shape-compatible input is actually mentioned. In fact, the present invention can also realize the mixed input of the sound form, that is, in the process of inputting the sound code, the word composed of one Chinese character can be compatible with the radical-character sound of the Chinese character. Code input method input.

In addition, the encoding of any word may omit its last code except the first code, or the last two codes, or the last three codes, ..., or the last (N-1) code, constituting the short code of the word. .

At present, there are two popular methods for selecting heavy codes. One is to arrange all the heavy codes in turn, use the up, down, left and right keys to select, move to the word to be input, and use the ok key to select. This method has many buttons, which is inefficient. . The second type is the long press technology, that is, according to the order of the re-coded arrangement, the weight code of the corresponding position is long pressed and the corresponding number is selected. If there is no current prompt line, use the up and down keys to scroll through the pages. This method is much better than the above technique, but the long press is shorter than the short press, and the position of the candidate is also found to be less efficient. The invention can not only use the above two methods to perform the re-code selection, but also creatively proposes a new three-line prompt function, which is a new re-code selection method based on the above-mentioned short code, and implements all the words. And a mixed input of full code and short code to further improve input efficiency. The specific way of the three-line prompt function is:

For any encoding of the input, the encoding itself is used as a candidate (the candidate is all composed of numbers). If you enter 234567, there is at least one weight, which is 234567 itself. Each prompt line shows 3 weights. For quick input, select 3 weights with ok, *, and # respectively. The above digital candidate words are generally arranged in the second position of the first screen of the prompt line, but in any case, when the input code (whether full code or short code) does not have a corresponding word except the digital candidate word, the first The digits display the number, and the second and third digits are displayed as empty.

In addition to this: (a) When the code length of the input code is 1, the first digit is a Chinese character (full code or short code), or an English letter, or other characters, the second digit is a number, and the third digit is The punctuation marks are then followed by other full code lengths of 1 bit, followed by all words with a short code of 1 bit. (b) When the input code is longer than 1 bit, when there is a corresponding full code, the first digit displays the most commonly used word in the full code, the second digit displays the number, and the third digit displays the most commonly used word in the shortcode. (If there is no corresponding short code, continue to display other full codes), then display the remaining full code weight code, then all the short code weight codes; when the code does not have the corresponding full code, the first bit shows the most commonly used one. Shortcode, the second digit displays the number, followed by all other shortcodes.

The biggest advantage of this three-line prompt function is that you can input without long press. No matter the first code, the second, third position of any screen in the prompt line, use the up and down keys to find the corresponding weight (first) After the screen does not need to press the up and down keys to turn the page), you can press ok, *, # directly to input, the efficiency is much higher than the long press technology. If 24, "Bu", "24", "Beijing" appear in the first, second, and third positions of the prompt line, press #Enter "Beijing" directly, press * to enter "24", press ok to enter "Bu". If the word does not appear on the first screen of the prompt line after inputting its code, press the up and down keys to turn the page. If you press 24, you should be able to enter "Beijing" (simply code can be 24), but enter 24 After the first screen of the prompt line is displayed "Bu", "24", "Beijing", there is no "Beijing", then you can find the word "Beijing" when you turn down the page.

The "sound code" mentioned in the present invention refers to the code 1 + code II. The "Chinese character" mentioned refers to the Chinese character itself.

The "character" referred to in the present invention refers to a character in any character set (such as ISO 10646 or Unicode GB18030, GBK, GB2312, BIG5, etc., and its extended set or subset).

In the character input method of the present invention, in the Chinese input system, the code of the punctuation mark is a number key corresponding to the first code of the sound code corresponding to the Chinese pronunciation; in the non-Chinese input system, the code of the punctuation mark is the punctuation The number key corresponding to the first letter of the corresponding foreign word of the symbol. For example, in an English input system, the code of the punctuation mark is the number key corresponding to the first letter of the corresponding English word of the punctuation mark. For example, the code of the punctuation mark ", " is the first one of "co wake up a". The number "2" corresponding to the letter "c". For another example, the code of the punctuation " . " is the number corresponding to the first letter "d" of " dot " The word "3", the code of ".net" is "3638", the code of com" is "3266", etc. Other punctuation marks can be analogized according to this rule.

The encoding rule is: N=8, using the improved 5 encoding rules. That is, the encoding of the Chinese character is determined according to the canonical code of the input method of the radical-character code, and the encoding rule of the word is: the first code of the encoding of all the characters + the weight of the last character encoded except the first code ( Longer than the N code, take the first N code). After encoding the word according to the coding rule of the word, a word consisting of two or more Chinese characters, when the code length is less than N code, is complemented by 0 after its coding. According to the above rules, as long as the longest code length N is determined, the encoding of all words is uniquely determined. In this way, the occupied computer has small memory and low system overhead, which is easy to implement.

Then a character input method in word units is generated. For example, the code of "three" is "111" (canonical code); the code of "three" is "342" (canonical code); the code of "three" is "13420" (the code of "three") One code + "one" specification code, the total length of the code is less than N code complement 0); the code of "computer" is "43123435" (the first code point of the specification code of "meter" + the specification code of "calculation" One yard 撇 + "machine" specification code), "not advance or retreat" code is "11251154" (the first three words of the first three words of the standard code horizontal and vertical + last Chinese character "return" the first five yards of the norm code ) "Indonesia" coded as "34511224" (the first four codes of the standard code of "撇点折横+"亚); the code of "People's Republic of China" is "23351325" (Vertical 撇撇撇 + "Country" The first 2 codes of the canonical code; the code for "T9" is "89"("t" + "9"); the code for "123456" is "123456"; the code for "smart ABC" is "35222" ( The first code of the standard code, ie, 撇, 折, + "A" 2, "B" 2, "C"2);"Mobile" code is "662453" ( "M" + "o" + "b" + "i" + "1" + "e");":" is encoded as "3" (the number corresponding to the first code of the colon code), "@α" is encoded as "4222", and the code for ":)" is 65 (colon) 6+ brackets 5) and so on.

Of course, the above code has a short form. For example: "three" shortcode is "1" or "11", "three" shortcode is "1" or "13" or "134" or "1342", "computer" shortcode is "4" or " """"""""""""""""""""""""""" "112511" or "1125115"; "Indonesia" is "3" or "34" or "345" or "3451" or "34511" or "345112" or "3451122"; "2" or "23" or "233" or "2335" or "23351" or "233513" or "2335132"; "T9" is "8"; "123456" is T or "12" or "123" or "1234" or "12345"; "Smart ABC" shortcode is "3" or "35" or "352" or "3522"; "Mobile" shortcode is "6" or "66" or " 662" or "6624" or "66245", "hh@a" shortcodes are "422", "42", "4", ":)" are encoded as 6.

In the implementation process, the above coding method adopts a three-line prompt function. If you press 3, the first digit displays "" (all the most common words in all words and short codes are 3), the second digit displays "3", and the third digit displays ",", such numbers and punctuation Symbols and other non-Chinese characters can be quickly entered; if you press 24, the first digit displays "Bu" (the most commonly used word in the full code), the second digit displays "24", and the third digit displays "Beijing" (Jane) The most commonly used word in the code), the efficiency is higher than the T9 new stroke input method in the contrast technology; if the first digit is "133111" when the 133111 is pressed, the second digit and the third digit have no corresponding weight code not displayed. Enter numbers directly, and more.

This implementation method can of course also be improved 4, the only difference is that when a word consisting of 2 or more Chinese characters, when the code length is less than N code, it is not added to 0 after its coding. For example, the code for "three" is "1342" and the code for short is "134", "13", "1".

Implementation Method 2: The selected keyboard definition is the same as the implementation method one. N=6, using the coding rules of Improvement 5 and Improvement 7. While having the advantages of implementing the first method, the Chinese characters that are unclear in the order of some strokes can be directly input using standard Chinese pinyin or sound code.

The word coding (full code and short code) differs from the implementation method one in that it takes longer than 6 codes to take the first 6 codes, such as the code of "China People's Republic" is "233513". In addition, a word consisting of one Chinese character can be compatible with standard Chinese pinyin or audio code input. For example, "code" can be input not only by way of implementing method 1, but also by pinyin 62 (ma) and its short code 6 input; Help "can not only be input by way of implementation method 1, but also can be input with pinyin 2264 (bang) and its shortcode 226, 22, 2, or with code 220 ( ba ) and its shortcode 22, 2 input, and so on.

Of course, in the specific implementation, you can use only standard Chinese Pinyin, or you can use only the audio code, or both.

Implementation Method 3: The selected keyboard definition is the same as the implementation method one. N = 6, using the coding rules of the improved 5, 6, and 7 lj, and the provisions of the fault-tolerant code are determined according to the basic coding rules.

The other codes are the same as the implementation method 2. However, the words composed of one Chinese character can also be compatible with the fault-tolerant code input. For example, the "code" can be input not only by the method of the second method, but also by the fault-tolerant code 0462 (the virtual radical is stone, The virtual font is coded and encoded as 0462, S ima) input. Of course, you can also use the 0462 shortcode 046, 04, 0 input. For example, "缰" can be input either by the method of the second method or by the fault-tolerant code 56055. (Io n 11) and its shortcodes 5605, 560, 56, 5 inputs, and so on.

Since a word consisting of one Chinese character can be input by using a fault-tolerant code, the input efficiency of a word composed of one Chinese character is greatly improved.

Implementation Method 4: The selected keyboard definition is the same as the implementation method one. N=6, the coding rules of the improved 3, 7 are adopted, and the provisions of the fault-tolerant code are determined according to the basic coding rules.

The other coding is the same as the implementation method three, but the last Chinese character of the word can be encoded with the fault-tolerant code, and

When the code length of a word consisting of two or more Chinese characters is less than the N code, it is not added to 0 after its encoding. For example, if N=6, the code of "computer" is 431234 ("the machine" specification code), or 436854 ("machine" error code, muj i); the code of "machine" is 123435 (canon code), or 6854 ( Fault-tolerant code, muji), of course, the above code also has a short form, such as "computer" shortcode is 43123, 4312, 431, 43, 4 or 43685, 4368, 436, etc., "machine" shortcode is 12345, 1234, 123, 12, 1 or 685, 68, 6, and so on.

Since the last Chinese character of all words can be input by using a fault-tolerant code, the input efficiency of the word is greatly improved.

Implementation Method 5: The selected keyboard definition is the same as the implementation method one. N=6, Chinese character is encoded by the radical-character code input method. The encoding rule of the word is the first code of all character encodings + the last code except the first code (more than 6 yards) Take the first 6 yards) and use the improvement ₇ .

Other codes are the same as the implementation method four, but words composed of two or more characters, other Chinese characters except the last Chinese character can also be input using a fault-tolerant code, and two or more characters composed of Chinese characters are used. The word composed does not add 0 to the end even if the total length of the code is less than N code. For example, the code of "institution" is: The first code of the code of "machine" is 1 (the first code of the canonical code) or 6 (the first code of the fault-tolerant code), The first 5 codes of the "construction" code are 12343 (canonical code) or 68468 (fault-tolerant code, mugou), then the "mechanism," codes are 112343, 612343, 168468, 668468, and their short codes are 11234, 1123, 112, 11, 1 or 61234, 6123, 612, 61, 6 or 16846, 1684, 168, 16 or 66846, 6684, 668, 66, and so on.

In this embodiment, any Chinese character constituting the word can be encoded using a canonical code or a fault-tolerant code, and the two can be arbitrarily combined, which is very convenient for the user. At the same time, because such a scheme uses 10 numeric keys for input, the potential of the numeric keypad can be fully utilized, and the input efficiency is also high, which is comparable to the input speed of the keypad pinyin hybrid input technology.

In the implementation methods three, four, and five, if the specification of the fault-tolerant code is determined according to the coding rule of the improvement 1 or the improvement 2, only the part of the fault-tolerant character of the partial Chinese character changes, and the specific implementation manner is basically similar to the implementation methods. If the improvement 1 is adopted, the "institution" in the implementation method 5 and the coding of the "machine" and "construction" in the third, fourth and fifth implementation methods are unchanged, but in the implementation methods three, four and five

The encoding of "箩" has changed. The original fault-tolerant font code is 55 and now it is 414. In addition, the "mechanism" in the implementation method 5 after the improvement 2, and the coding of the "machine" and "construction" in the implementation methods 3, 4, and 5 have also changed. The code of the "machine" is 123435 (the specification code) ) or 6835 (fault-tolerant code, mu35), the code of "construction" is 123435 (canonical code) or 683554 (fault-tolerant code, mu3554), then

The codes of "institutions" are 112343, 612343, 168355, 668355. Of course, their short codes have also changed accordingly. For example, the short code of "machine" is 12345, 1234, 123, 12, 1 or 683, 68, 6, etc. Wait.

Implementation Method 6: The following implementation method 5 is limited: When a Chinese character has both a normal code and a fault-tolerant code, when encoding a word composed of 2 or more characters, only the fault-tolerant code of the Chinese character is used. coding. Thus, the number of codes of words consisting of two or more characters can be greatly reduced.

The other codes are the same as the implementation method 5, but the Chinese characters in the words consisting of 2 or more characters use the canonical code if there is only the canonical code and no fault-tolerant code, and in any other case, only the fault-tolerant code is used, and the normal code is not used. . For example, the code of "institution" is 668468 (the first code of "the machine" takes the fault-tolerant code, the "construction" takes the first 5 codes of the fault-tolerant code), and the shortcodes are 66846, 6684, 668, 66, and so on. This improvement scheme has a small total number of codes and consumes less computer space, which is very suitable for embedded devices with strict memory space requirements.

Implementation Method 7 The selected keyboard is defined as - key position tone code tone code number English letter / standard Chinese pinyin

1 z c 1 1

2 abc 2 2 a 3 def 3 3 def

4 g h i 4 4 g h i

The coding rule is: N=6, Chinese characters are encoded by audio code. The encoding rules of words are: the first code of all characters + the last code encoded by the last code except the first code (before the first 6 codes of 6 codes), and it is specified that when a word is composed of two or When the last character of two or more characters is a Chinese character, and the code length of the word is less than N code, the tone code of the last Chinese character is added after the word is encoded.

Then a character input method in word units is generated. Such as: "Three" code is "726" (san);

The code for "one" is "42" (ge); the code for "three" is "7424" (s+ge+4); the code for "computer" is "57541" (j+s+ji+1), "No advance or retreat" code is "259884" (b+j+z+tui);

"Indonesia" code is "936992" (y+d+n+x+ya); "People's Republic of China" code is "147644" (z+h+r+m+g+h); "T9" code The code for "89" ( "t" + "9" ); "123456" is "123456"; the code for "smart ABC" is "16222" ( έ+η+ " A" + "B" + "C" );

The code for "Mobile" is "662453" ( "M" + "o" + "b,, + "i" + "1" + "e" ); the code for ": " is "3" (the code for the colon) The number corresponding to the first code), the code of "h @a" is "4222",

The code for ":) " is 65 (colon 6 + bracket 5) and so on.

The above codes are all in short form, for example: "three" short code is "72" or "7", "single" short code is "4", "three" shortcode is "742", "74" "or" 7", the "computer" shortcode is

"5754,, "575", "57" or "5", the shortcode for "not advance or retreat" is "25988", "2598",

The short codes for "259", "25", "2", "Indonesia" are "93699", "9369", "936",

"93" or "9", "People's Republic of China" shortcode "14764", "1476", "147,, "14,, or "1", "T9" shortcode is "8", "123456 "The shortcodes are "12345", "1234", "123",

"12,, or ' "1", "Smart ABC" has the shortcode "1622", "162", "16" or "1", and the short code of "Mobile" is "66245", "6624", " 662", "66" or "6", the shortcode for "ha@a" is

The short code for "422", "42" or "4", ":)" is "6".

The implementation method 8 selects the keyboard and the coding rule are the same as the implementation scheme 7, and stipulates that the words composed of one Chinese character can be compatible with the standard Hanyu pinyin input. Other codes are exactly the same as those in Embodiment 7, but words composed of one Chinese character can also be input with its standard Chinese Pinyin. For example, "quasi" can be input not only by the method of Embodiment 7, but also by 9486 (Zhun). Or its shortcode 948, 94, 9 input, and so on.

Implementation Method 9 The selected keyboard and encoding rules are the same as Embodiment 8, and if a word consisting of 2 characters is used, the 2 character encoding (longer than the N code of the first N code) constituting the word is input.

The other codes are exactly the same as in the eighth embodiment, but the wording rules of the two-character word have changed. For example, the code of "three" is "726434" (san+ge+4), and its short code is 7, 72. , 726, 7264, 72643, etc. The advantages are: For all words composed of Chinese characters and encoded by the phonetic code (excluding words consisting of 1 Chinese character encoded by Chinese Pinyin), the word length consisting of 1 Chinese character is 2-4 codes. The word length consisting of 2 or 3 Chinese characters is 5-6 codes, and the other word lengths are 6 codes. The words consisting of 1 Chinese character and the full code of words consisting of 2 or more Chinese characters. No re-sequence occurs, which is convenient for computer processing.

Embodiment 10: The selected keyboard and encoding rules are the same as Embodiment 9, and if the word consists of 3 characters, the first code + the last two characters of the first character are encoded (before the N code is taken) N code).

The other codes are exactly the same as those in Embodiment 9, but the wording rules of the three-character word have changed. For example, the code of "computer" is "578265" (j+suan+j), and its shortcode is 5, 57. 578, 5782, 57826, etc. The advantages are: "Calculation" is coded as "547826" (ji+suan), shortcodes are 5, 54, 547, 5478, 54782, and "computer system" is coded as "575944" (j+s+j+xi +4) , the shortcodes are 5, 57, 575, 5759, 57594. The shortcodes for "computation" and "computer" are the same except for the code length of 1. The other cases are different, and the "computer system" and "computer" "The shortcode is the same as the code lengths of 1 and 2, and the other cases are different. You can get the quickest input of the three words.

The eleventh method of selecting the keyboard and the encoding rule is the same as the tenth embodiment, and that when the code I of the Chinese character is 2, c, S, the zh, ch, sh can be used as the encoding of the audio code I; There are r in the code II! You can use ng instead of I to encode the code II; the encoding of the Chinese character = the code of the Chinese character. The numeric key corresponding to the encoding of the Chinese character + the numeric key of the encoding of the Chinese character.

The other codes are exactly the same as those of the implementation scheme ten, but if the characters constituting the words have Chinese characters, and the first two codes of the standard Chinese pinyin of the Chinese characters are zh, ch or sh, or the latter two codes are ng, the coding of the word is fault-tolerant. The form of the code, that is, when the code 1 of the Chinese character is 2, c, S, zh, ch, sh can be used as the code of the code I; when the code II of the Chinese character has II, you can use ng Instead of η constitutes the code II Encoding; encoding of Chinese characters = numeric key corresponding to the encoding of the Chinese character's audio code I + digital key corresponding to the encoding of the Chinese character's audio code II. If "preparation" meets the above conditions, not only can it be input according to the method of the tenth embodiment, but also has the form of the fault-tolerant code "948622" (zhun+be), "standardization" can be input according to the method of the tenth embodiment, and has a fault-tolerant code" The form of 294864" (b+zhun+h), of course, these fault-tolerant codes also have the form of short codes, and so on.

Implementation Method 12 The selected keyboard and coding rules are the same as Embodiment 10, and it is stipulated that a word consisting of one Chinese character can be input in accordance with the input method of the radical-character code.

The other codes are exactly the same as those of the tenth embodiment, but the words consisting of one Chinese character can be input not only in the method of the tenth embodiment but also in the input method of the radical-character code input. For example, the "machine" can be compatible with its canonical code 123435, and the error-tolerant code 6854 (muji) input, these codes also have the form of short codes, and so on. Compared with the prior art, the present invention has the following significant advantages:

1. Input by word, the average code length is short, the repetition rate is low, and the input efficiency is high;

2. For Chinese characters, Pinyin pen-shaped mixed input can be realized, which improves the input efficiency;

3. The character input method of the present invention has a low learning starting point, and the coding is natural and smooth, easy to learn and use;

4. It has strong versatility. When the input state is not switched, various characters such as Chinese characters, numbers, punctuation marks, and English letters can be mixed, which greatly improves the input efficiency.
