Purpose of the present invention is exactly will be on the basis that keeps conventional numeral-English keyboard style, and the combination rule of utilization Chinese phonetic alphabet generates a class new Digital QWERTY keyboard, to overcome above-mentioned deficiency that exists and defective.And at the numeral-English keyboard that guarantees to use among the present invention, on the basis of each key bit multiplex frequency equilibrium, further the whole phonetic annotations of Chinese characters among large-scale character set such as GBK, the GB18030-2000 are imported in realization quickly and easily in the input Chinese phonetic alphabet process.
Technical essential of the present invention as Fig. 3, Fig. 4, shown in Figure 5 and be attached in the Embedded Intelligent Terminal product, forms Fig. 6 or Fig. 7.
One of technical essential of the present invention is the multiplexing English alphabet abc of digital 1 key; The multiplexing English alphabet def of numeral 2 keys; The multiplexing English alphabet gh of numeral 3 keys; The multiplexing English alphabet ijk of numeral 4 keys; The multiplexing English alphabet lmn of numeral 5 keys; The multiplexing English alphabet op of numeral 6 keys; The multiplexing kue rs of numeral 7 keys; The multiplexing English alphabet tu of numeral 8 keys; The multiplexing English alphabet vwx of numeral 9 keys; Numeral 0 key multiplexing English alphabet yz and+.The multiplexing style of English alphabet on numeral-English keyboard among the present invention and many mobile phones, the telephone set is in full accord as can be seen from Fig. 6 or Fig. 7, be on the concrete numerical key multiplexing English alphabet variant.
English alphabet multiplexing method on the above-mentioned numeral-English keyboard, the principle of institute's foundation is the combination rule of conventional phonetic transcriptions of Chinese characters letter:
Rule 1: the Chinese character that each is conventional, its first phonetic alphabet can only be following selections:
[a, b, c, d, e, f, g, h, j, k, l, m, n, o, p, q, r, s, t, w, x, y, z] be totally two ten three English alphabets.
And English alphabet [i, u, v] then can not occur.
Rule 2: the phonetic English alphabet string that each is conventional, the input of the follow-up English alphabet of first phonetic alphabet can only be imported one of following ten letters, the character set S that they constitute: S=[a, e, i, o, u, g, h, n, r, v].
Here English alphabet v is used for substituting the phonetic alphabet ü of " Scheme for the Chinese Phonetic Alphabet ".
Rule 3: English alphabet h can only follow at English alphabet c, s, and the back of z constitutes phonetic alphabet: ch, sh, zh.On the contrary, English alphabet g but can not follow English initial c, s, z input.Therefore gh can only be inconsistent input as the input of the English word string of follow-up phonetic.
Rule 4: English alphabet r can only follow in the back as first phonetic alphabet e, constitutes the pronunciation of " er ".Simultaneously, there is not simple " eo " pronunciation in conventional Chinese character pronunciation.
Numeral-English keyboard among the present invention, be exactly the principle according to above-mentioned four regularity, again English alphabet multiplexing on the numerical key made new integration, make each numerical key, can only arrange unique among a character set S character, two exceptions are wherein arranged, and are exactly digital multiplex key<gh〉and<opqr 〉, but according to rule 3,4, when the Chinese phonetic alphabet is imported, when pressing these two numerical keys, during as the follow-up input of phonetic word string, but a letter can only appear legally.
When using this numeral-English keyboard to import the Chinese phonetic alphabet, following characteristics are arranged:
The first English alphabet input of phonetic word string needs to determine the number of times of stroking according to the ordering in the numerical key at this alphabetical place.As import chuang, if according to layout one, the numerical key at first letter of pinyin c place is<abc 〉, and be arranged on the 3rd position, so need knock this key continuously three times, could inputting English letter c.
When the follow-up phonetic alphabet of phonetic word string are imported, only need to locate the position of follow-up phonetic alphabet exactly by once.Under the situation of layout one, behind input chuang initial c, by<gh〉key table shows that the user is just at input alphabet h, by<stu〉key can only be input alphabet u, by<abc〉key input a, then<and lmn〉key input n, press at last<gh key input Pinyin letter g.
In the Embedded Intelligent Terminal product, during as the numeral-English keyboard input Chinese phonetic alphabet among use the present invention on mobile phone, card printer, PDA or the palm PC, its built-in system software can use process flow diagram as shown in Figure 8, realizes that the Chinese phonetic alphabet imports fast, easily.Its main method is as follows:
A. at first set up character set S=[a, e, i, o, u, g, h, n, r, v ,+] and the numerical key mapping table.For multiplexing layout one: 1-a, 2-e, 3-gh, 4-i, 5-n, 6-or, 7-u, 8-v, 9-+; For layout two: 2-a, 3-e, 4-gh, 5-i, 6-n, 7-or, 8-u; For layout three: 2-a, 3-e, 4-gh, 5-i, 6-n, 7-or, 8-u, 9-v; Put current " phonetic word string input block " simultaneously for empty, then, system enters first phonetic alphabet input state, and waits for and knock the numerical key of first letter of pinyin correspondence.
B. first phonetic alphabet input state: certain numerical key that knocks the first letter of pinyin correspondence continuously, so-called keystroke continuously, refer to linking the time interval of knocking same key for twice must not be less than certain time period, then according to the number of times that knocks continuously, determine the first letter of pinyin of current input: as numerical key<1〉last multiplexing English alphabet<abc 〉, then knock for the first time numerical key<1〉time, input Pinyin initial " a ", keystroke is 2 times continuously, input Pinyin initial " b ", keystroke is 3 times continuously, input Pinyin initial " c "; Continuously keystroke is 5 times, then samsara input Pinyin initial " b ", recursion according to this again; At last, when knocking other key, or stop to knock this key interval greater than certain value the time, then system will determine that the English initial of the phonetic of importing sends into current " phonetic word string input block "; Then, system enters follow-up phonetic alphabet input state;
C. follow-up phonetic alphabet input state: each numerical key that the user is knocked, if the multiplexing English alphabet of this numerical key is not<gh〉or<opqr 〉, then, deliver to current " phonetic word string input block " directly with English alphabet corresponding in the numerical key mapping table.For example for layout one, the user knocks<1〉key input " a ", knock<2〉key inputs " e " or the like.If the user is current knock be<gh key, distinguish then whether current input is positioned at English alphabet " c ", " s ", " z " second phonetic alphabet afterwards, "Yes" shows that then the phonetic alphabet of input are " h ", and the English alphabet that "No" is then imported is " g "; That knock is multiplexing key<opqr if the user is current 〉, distinguish that then whether current input is the input immediately following English alphabet " e ", if then be " r " input, otherwise be that " o " imports.
D. when " phonetic word string input block " is not empty, system is according to the current substring of input Pinyin, and the phonetic code table of internal system--be the code table mapping relations of the pairing Chinese character set of each legal phonetic word string, the definite Chinese Character Set that may import, and these Chinese characters are shown, select input for the user.
Numeral<yz+〉the multiplexing special symbol "+" of key is also replaceable is other symbol, perhaps omit.
Advantage of the present invention is mainly reflected in:
1, the conventional numeral-English keyboard input Chinese phonetic alphabet is compared and is used QWERTY keyboard input Chinese phonetic alphabet word string, will cause user's number of taps multiplication.Even utilize the relevance between the phonetic alphabet, use the intelligence phonetic letter input method, also can't fundamentally overcome on the conventional numeral-English keyboard, because the English alphabet layout method is unreasonable, and the unbalanced phenomenon of alphabetical channelized frequencies that causes.And numeral-English keyboard layout of the present invention, owing to meet the combination rule of Chinese phonetic alphabet, and when therefore being used to import the Chinese phonetic alphabet, than the workload of using QWERTY keyboard, a Chinese phonetic notation of average every input word string, 0.7 stroke of only many increases.
2, can finish the phonetic input of GBK, GB18030-2000 large character set.On numeric keypad, realize first finishing the easy input of large character set phonetic word string with minimum touch potential.
3, because the English digital keyboard layout among the present invention meets the combination rule of the Chinese phonetic alphabet, so Embedded Intelligent Terminal, can develop very easily based on the intelligence phonetic letter Input Software on the numeral-English keyboard of the present invention.
4. technical characterstic of the present invention also is numeral<yz+〉the multiplexing special symbol of key+, can be used for the special pronunciation of some Chinese characters of large character sets such as GBK or GB18030.Phonetic word string as " " is aes, and numeral-English keyboard of the present invention, except first letter of pinyin can be imported " s ", the follow-up English alphabet of a legal phonetic word string (seeing conventional phonetic word string tabulation) cannot be " s " .So the present invention can replace it with Pinyin coding " ae+ " .In addition as:Ceok ceok, because conventional phonetic subsequent character cannot be " k ", therefore, improved Pinyin coding then is: " ceo+ ".
Because the Chinese character of this unconventional pronunciation is an only a few in the large character set, and many is rarely used words, the CJK that mainly comes from the Unicode coding unifies Chinese character, CJK has collected 20902 of Chinese characters altogether, according to the data of having grasped, these Chinese characters have 27834 phonetic forms at least, and comprise a word multitone phenomenon.Wherein various unconventional pronunciations only have 159.Therefore symbolization "+" can't be increased in the inconvenience that causes in the Chinese character input in the Pinyin coding, but can give the solution of the comprehensive large character set phonetic input of user's one class.
Embodiment:
As shown in Figure 9: under the situation of layout one, in the conventional Chinese phonetic alphabet word string form, the Chinese phonetic alphabet is a Bing (complication ice ...) transition coding be B453, corresponding numerical coding is 11453, wherein 11 the expression 1 key be B by the double hit secondary.The Chinese phonetic alphabet is that Dong (moves and understands the hole ...) transition coding be D653, corresponding numerical coding is 2653, wherein 2 expressions, 2 keys are knocked once and to be D.The Chinese phonetic alphabet is that (catch table pecks Zhuo ...) transition coding be Z376, corresponding numerical coding is 99376, wherein 99 the expression 9 keys be Z by the double hit secondary.The Chinese phonetic alphabet is Peo+ (Peol ...) transition coding be P269, corresponding numerical coding is 66269, wherein 66 the expression 6 keys be P by the double hit secondary.
