Description

Chinese character input output method and device

Technical field

The present invention relates to Chinese character input output method and device, more particularly, relate to and use dialing keyboard (dial keypad) or computing machine with input medias such as keyboard device and method of input and output Chinese character rapidly and simply on e-machines such as mobile communication terminal or computing machine.

Background technology

Middle national language is different with phonographys such as English or Korean, belong to ideograph, literal quantity reaches tens thousand of, therefore, literal can not be assigned to correspondingly on the keyboard of wired or wireless terminating machines such as computing machine, laptop computer, set-top box (set top box), phone, mobile communication terminal, individual mobile communication terminal machine, individual portable terminal, wireless data terminal machine, frequency sharing communications terminal, smart mobile phone (smart phone), automaton.Therefore, for national language in the inputs such as the keyboard that can use a computer, mainly use Chinese phonetic alphabet input mode and the Five-stroke Method input mode.

Chinese phonetic alphabet input mode be in input during national language no matter tone how, the mode that the pronunciation of middle national language is represented and imported with English.Here the said Chinese phonetic alphabet is to use the initial consonant and the simple or compound vowel of a Chinese syllable of letter, represents the literal of middle national language (Chinese) with phonogram.But pronunciation only represented in letter, and it is too much to have a Chinese character of same pronunciation, therefore just must be from a plurality of Chinese characters (dozens of is generally arranged) when literal of input with same pronunciation in turn selection want the Chinese character imported.Like this, the expensive time of meeting in this process, thereby have the problem that is difficult to import fast Chinese character.

The Five-stroke Method input mode is to be that unit decomposes Chinese character with the grapheme, and making up the mode that Chinese character is imported by the combination of the keyboard corresponding with each grapheme, the problem of existence is: non-Chinese character input professional's common people are difficult to by learning skilled use.That is, if Chinese character is considered as a whole its structure major part is all very complicated, with the grapheme the hard to tackle complexity of process that unit decomposes such Chinese character, common people are not easy to understand well, use its rule.And, be arranged with a plurality of (maximum 12) grapheme on each keyboard, therefore be difficult to remember and use rightly the combination of keyboard.Therefore, just exist for use this method expertly import in national language, must be through making great efforts for a long time and the problem of training.

In addition, Korea S's special permission discloses 1983-0003768 number and has proposed " Chinese computing machine input method ", it is characterized in that this method is by the step that Chinese character is divided into horizontal stroke, vertical stroke, some stroke, oblique line stroke, clockwise direction stroke, counter clockwise direction stroke, right rotation stroke and anticlockwise stroke; With

equivalence numeral

1,2,3,4,5,6,7 and 8 steps of giving above-mentioned stroke respectively; And, preferential with stroke from top to bottom, with from left to right stroke is the stroke order of the Hanzi structure of next, the step that above-mentioned equivalent numeral is input to input system constitutes, when above-mentioned clockwise direction stroke, right rotation stroke and when counterclockwise there are part more than 2 in stroke, anticlockwise stroke, at above-mentioned equivalence numeral, add respectively and the corresponding secondary symbol numeral of clockwise direction stroke, right rotation stroke and counter clockwise direction stroke, the anticlockwise stroke of above-mentioned part.But because by importing Chinese character with the input process of the stroke similar number of Chinese character, spended time when therefore importing the many Chinese character of stroke so just has the problem that is difficult to import fast Chinese character.

Summary of the invention

The present invention proposes in order to solve above-mentioned existing issue, its objective is a kind of such Chinese character input-output unit and the method for providing: the characteristic features that the characteristic morphology of Chinese character is divided into predetermined number, by with the combination of the phonetic alphabet of Chinese character, be implemented in and import rapidly and simply on mobile communication terminal or the computing machine and show Chinese character.

To achieve these goals, as a technical scheme of the present invention, be used to import and show that the Chinese character input output method of Chinese character may further comprise the steps: (a) step of the capitiform feature of the required Chinese character of input, above-mentioned capitiform feature is after extracting the morphological feature of radicals by which characters are arranged in traditional Chinese dictionaries of the top be positioned at each Chinese character or radical out it to be deformed into simple form, and the mutually similar form of the form after this distortion is divided into a class, (b) demonstration has the step of the alternated Chinese character of the capitiform feature of being imported on display device, and, (c) after the user will be chosen in the information input of 1 Chinese character in the alternated Chinese character shown in the above-mentioned display device, with selected Chinese Character Recognition is required Chinese character, outputs to above-mentioned display device.

In addition, as other technical scheme of the present invention, be used to import and show that the Chinese character input-output unit of Chinese character comprises: data input device, the user can import the characteristic information of required Chinese character by a plurality of keys, and the corresponding data-signal of above-mentioned characteristic information that generates and imported; Storer makes the characteristic information and the identification lettering data base system corresponding with characteristic information of each Chinese character and each Chinese character and stores; Control part is from above-mentioned database retrieval and the corresponding Chinese character of above-mentioned data-signal; Display device shows the above-mentioned characteristic information and the above-mentioned Chinese character that retrieves of above-mentioned required Chinese character.

Embodiment

At present, the radicals by which characters are arranged in traditional Chinese dictionaries of national language always have 189 in the simplified Chinese character that China uses, and the radicals by which characters are arranged in traditional Chinese dictionaries that comprise in about 3,500 everyday characters of China's regulation are 186.In the present invention, according to the characteristic morphology that appears at Chinese character top and radical, 184 radicals by which characters are arranged in traditional Chinese dictionaries extractions from the radicals by which characters are arranged in traditional Chinese dictionaries that are attached to the literal below except strokes and dots radicals by which characters are arranged in traditional Chinese dictionaries (') and only being used for are 28 kinds of characteristic features altogether.Below for convenience of description and easy to understand, with the characteristic features called after " capitiform feature " that the present invention extracted out.The radicals by which characters are arranged in traditional Chinese dictionaries of middle national language are to be included in the Chinese character with the literal form of (simplifying the back) after original literal form or the distortion, but it is irrelevant with the original form of radicals by which characters are arranged in traditional Chinese dictionaries in the present invention, but with the actual state of seeing, promptly the literal form after the distortion is that benchmark is extracted the capitiform feature out.

On the other hand, the existing Chinese character that independently forms with 1 radicals by which characters are arranged in traditional Chinese dictionaries in the Chinese character also has several radicals by which characters are arranged in traditional Chinese dictionaries to merge the Chinese character that forms.In addition, radicals by which characters are arranged in traditional Chinese dictionaries have be arranged in about, be arranged in about, cover left side and epimere, covering left side and hypomere, encirclement integral body etc. all forms.Like this, when from diversified Chinese character, extracting the capitiform feature out,, we can say that a kind of extraction method with consistency is very important with regard to the problem of the capitiform feature of extracting which position out is arranged.

The following process that the capitiform feature of extracting Chinese character out is described according to the present invention.

Capitiform feature extraction method of the present invention be with from the top that is positioned at Chinese character or the radicals by which characters are arranged in traditional Chinese dictionaries of radical to extract out be principle, based on this whole Chinese characters are divided in the middle of top or the radical any to have the Chinese character of 1 capitiform feature and the Chinese character that on top and radical, has 2 capitiform features.

Fig. 1 is the classification chart of 28 kinds of capitiform features that the present invention extracts out, demonstrates the class number of corresponding capitiform feature, according to identification lettering, the representative Chinese character of corresponding capitiform feature and the Chinese phonetic alphabet of corresponding representative Chinese character of morphological feature after with corresponding capitiform characteristic symbolization.At this moment, the address of doing the identification lettering used in the Chinese phonetic alphabet of corresponding representative Chinese character.This is for convenience of description and is more readily understood the present invention, and in the actual application of national language, is not only form and also can distinguishes the capitiform feature by voice in the keyboard input of use a computer keyboard or mobile communication terminal.

In Fig. 2 a～Fig. 2 b,, the radicals by which characters are arranged in traditional Chinese dictionaries that belong to the capitiform feature that is divided into 28 kinds have altogether been put in order according to capitiform feature extracting method of the present invention.And " corresponding literal " hurdle example of passing the imperial examinations at the provincial level illustrates difficult Chinese character with the capitiform feature of extracting radicals by which characters are arranged in traditional Chinese dictionaries out.The characteristic morphology of corresponding Chinese character is extracted out as the capitiform feature of corresponding Chinese character with the most similar capitiform feature when 28 kinds capitiform feature is not quite identical altogether.

Expression.

Like this, with capitiform feature 1～28 corresponding in the radicals by which characters are arranged in traditional Chinese dictionaries of national language or Chinese character have and the homomorphosis of each identification lettering or similar feature, thereby the capitiform feature extracted out in the most of corresponding literal that is subordinated to each capitiform feature easily.

The capitiform feature is to extract out from the radicals by which characters are arranged in traditional Chinese dictionaries of top that is arranged in Chinese character or radical, thereby has both had the Chinese character that has only 1 capitiform feature, also has the Chinese character with 2 above capitiform features.In the single capitiform feature Chinese character of 1 capitiform feature is only arranged, can the corresponding capitiform feature of very fast extraction, and in Chinese character, must determine to extract out the process of which type of capitiform feature earlier with a plurality of capitiform features.The method of extracting the capitiform feature in these Chinese characters with a plurality of capitiform features out below is described.

Chinese character with a plurality of capitiform features is divided into: from the upper left-hand of word to a plurality of capitiform features of the transversely appearance on right side, and these capitiform features interconnect the Chinese character of (independent); And, from the upper left-hand of word to a plurality of capitiform features of the transversely appearance on right side, and these capitiform features do not connect the Chinese character of (independence) mutually.But according to the difference of independence situation, the capitiform feature difference of extraction.

For having the not Chinese character of independently a plurality of capitiform features, only extract 1 the corresponding capitiform feature of capitiform feature conduct that is positioned at the leftmost side, top out.

Chinese character with independently a plurality of capitiform features is divided into: top occurs 2, and independently 3 independently Chinese characters of capitiform feature appear in the Chinese character and the top of capitiform feature.For the Chinese character that 2 capitiform features occur, extract the capitiform feature in left side and the capitiform feature on right side successively out.

Both there had been the separate Chinese character of each capitiform feature in the Chinese character that 3 capitiform features occur, also existed to have 1 independently the capitiform feature and the Chinese character of 2 capitiform features independently not mutually simultaneously.For 3 Chinese characters that the capitiform feature is separate, be to extract out as corresponding capitiform feature except the capitiform feature on left side the capitiform feature at middle part and right side,, 1 capitiform feature independent mutually for 2 capitiform features be Chinese character independently, extract 1 capitiform feature out from capitiform feature independently, simultaneously will be not independently in 2 capitiform features the capitiform feature in left side extract out as corresponding capitiform feature.

Below describe the extraction method of capitiform feature of the present invention for example in detail.

I. the Chinese character (single capitiform feature Chinese character) of 1 capitiform feature only appears in top and radical

Because only contain 1 capitiform feature, therefore can extract corresponding capitiform feature simply out on top and radical.For example, capitiform feature " mouth " is only contained on the top of " star ", thereby extracts the 17th capitiform feature " mouth " out; Capitiform feature " moon " is only contained on the top of " together ", thereby extracts the 18th capitiform feature " moon " out.

II. from epimere left side to the Chinese character that a plurality of capitiform features transversely occur on right side

1. has the not Chinese character of independently a plurality of capitiform features

Only extract the capitiform feature that is positioned at the left side out.For example, the top of " liter " comprises the 25th capitiform feature " thousand " and the 15th capitiform feature " ten ", but because these 2 capitiforms are characterized as continuous form, thereby only extract the capitiform feature that is positioned at the left side out.Therefore the 25th capitiform feature " thousand " is extracted out.

2. the Chinese character that has independently a plurality of capitiform features

(1) has the Chinese character of 2 capitiform features

Extract the capitiform feature on left side and right side successively out.For example, the 15th capitiform feature " ten " and the 20th capitiform feature " people " appear respectively in the left side of " all " and right side, extract the 15th capitiform feature " ten " out as the capitiform feature of going ahead of the rest, and extract the 20th capitiform feature " people " out as follow-up capitiform feature.Other example has, and same the 16th capitiform feature " wood " that occurs in the left side of " woods " and right side because corresponding capitiform feature is separate, is therefore extracted 2 capitiform features " wood " out.

(2) has the Chinese character of 3 capitiform features

＜3 Chinese characters that the capitiform feature is all separate 〉

Except that the capitiform feature of central authorities, extract the capitiform feature on left side and right side successively out.For example, " debate " according to the order from the upper left-hand to the right side the 6th capitiform feature " speech " appears successively, the 14th capitiform feature " is ended " and the 6th capitiform feature " speech ", extracts 2 the 6th capitiform features " speech " out as in advance capitiform feature and follow-up capitiform feature.In addition, " paste " the 9th capitiform feature " mountain ", the 15th capitiform feature " ten " and the 18th capitiform feature " moon " occur successively according to the order from the upper left-hand to the right side, extracts the 9th capitiform feature " mountain " and the 18th capitiform feature " moon " successively out respectively as capitiform feature and the follow-up capitiform feature of going ahead of the rest.

＜1 capitiform feature is independent, 2 capitiform features Chinese character independently not mutually

From capitiform feature independently, extract 1 capitiform feature out,, go out as corresponding capitiform features thereby extract 2 capitiform features altogether out from can from the capitiform feature of independently not extracting out 2 capitiform features mutually, extracting the capitiform feature that is positioned at the left side out.For example, " Russia " can be decomposed into " I ". Be and the corresponding radicals by which characters are arranged in traditional Chinese dictionaries of the 25th capitiform feature " thousand ", thereby according to The 25th capitiform feature " thousand " is extracted out as the capitiform feature of going ahead of the rest, " I " be though comprise the 25th capitiform feature " thousand " and the 28th capitiform feature " ring ", but because be the Chinese character that the capitiform feature (i.e. the 25th capitiform feature " thousand ") in left side is extracted out as corresponding capitiform feature, thereby can extract the 25th capitiform feature " thousand " out as follow-up capitiform feature from " I ".

That is, from single capitiform feature Chinese character that 1 capitiform feature is only arranged and have a plurality of mutually not independently the Chinese character of capitiform feature extract 1 capitiform feature out, extract 2 capitiform features out from Chinese character with independently a plurality of capitiform features.

Below explanation utilizes dialing keyboard or computing machine will contain the Chinese character input of such 28 kinds of capitiform features and output to the method that mobile communication terminal or computing machine etc. install with keyboard.

Chinese character input output method of the present invention uses simultaneously according to the Chinese phonetic alphabet represents that method pays first letter of English alphabet of each Chinese character and the capitiform feature of extracting out according to capitiform feature extraction method of the present invention.Promptly, use dialing keyboard or computing machine with key input apparatus such as keyboards, after by predefined procedure the Chinese phonetic alphabet and capitiform feature being input to Chinese character output devices such as mobile communication terminal or computer monitor, from the suggested a plurality of Chinese characters of this device, select required Chinese character.

Below explanation can be carried out the Chinese character input-output unit of such Chinese character input.

With reference to Fig. 3, be depicted as Chinese character input-output unit of the present invention on the figure.This Chinese character input-output unit comprises key input apparatus (10), control part (20), storer (30) and display part (40).

Key input apparatus (10) is the user input apparatus of e-machines such as the keyboard of keyboard, computing machine of mobile communication terminal or touch-screen, comprises a plurality of keys that expression has identification lettering, letter and number etc. respectively.After the user selects certain key, the key data corresponding with selected key, promptly information such as capitiform feature, letter and number are sent to control part (20).The allocation scheme of capitiform feature, letter and number is elaborated later on again.

The middle national language Chinese character of about 3,500 everyday characters that China's rule are predetermined all makes data base system with capitiform characteristic information separately and Chinese phonetic alphabet information etc. and is stored in the storer (30).

Control part (20) is from the database retrieval of storer (30) Chinese character corresponding with the key data that sends from key input apparatus (10) and be sent to display part (40).

Display part (40) is the device that shows Chinese character, and for example, the top of screen is formed with Chinese character output hurdle (40A), and the bottom of screen is formed with Chinese character and arranges hurdle (40B).It is the Chinese character that the database retrieval from storer (30) goes out that Chinese character is arranged what show in the hurdle (40B), and what show in Chinese character output hurdle (40A) is the Chinese character that the capitiform Feature Recognition lettering imported of user or user select.

Fig. 4 illustrates the keyboard as the mobile communication terminal of the present invention of an example of key input apparatus (10).On keyboard, capitiform Feature Recognition lettering of the present invention is assigned on each button, and the distribution of button considers that preferably the frequency of utilization of this identification lettering decides.

Referring to the keyboard among Fig. 4, capitiform Feature Recognition lettering and English alphabet are assigned on each button with numeral.

Be assigned on the numerical key 1 and capitiform feature " water ", " ending ", " one ", identification lettering that " ear " is corresponding

And English alphabet " B, C, A ", be assigned on the numerical key 2 with the capitiform feature " determine ", " speech ", identification lettering that " well " is corresponding

And English alphabet " D, F, E ", be assigned on the numerical key 3 and capitiform feature " river ", " moon ", " people " corresponding identification lettering

And English alphabet " G, H, I ", be assigned on the numerical key 4 and capitiform feature " meter ", " ten ", identification lettering that " heart " is corresponding

And English alphabet " J, K ", be assigned on the numerical key 5 with the capitiform feature " beat ", " king ", " mountain " corresponding identification lettering

And English alphabet " L, M ", be assigned on the numerical key 6 with capitiform feature " silk ", " factory ", identification lettering " one " that " cutter " is corresponding, And English alphabet " N, P, O ", be assigned on the numerical key 7 and capitiform feature " tea ", identification lettering that " wood " is corresponding And English alphabet " Q, R ", be assigned on the numerical key 8 and capitiform feature " mouth ", " in vain " corresponding identification lettering

And English alphabet " S, T, U ", be assigned on the numerical key 9 and capitiform feature " thousand ", " eight " corresponding identification lettering

And English alphabet " W, X, V ", be assigned on the numerical key 0 and capitiform feature " noon ", " power ", identification lettering that " ring " is corresponding And English alphabet " Y, Z ".Simultaneously, be assigned other special token (◎) with capitiform Feature Recognition lettering on the numerical key 1, this is the means that prevent input error that are used as in the national language input process in of the present invention, and more detailed content describes later on again.

On the keyboard of mobile communication terminal of the present invention, when the telephone number that input is used to converse, identical with the method for the digital input key that uses other device, pressing note has the key of respective digital, numeral just is transfused to, and in input under the situation of national language Chinese character or English alphabet, operate after other function key is converted to English/Chinese character input mode with call mode, use corresponding key to come input characters.

The method of inputting English letter is identical with the method for using common dialing keyboard inputting English letter.For example, press numerical key 1 next time with English input pattern, first English alphabet " B " that then is assigned on the numerical key 1 is presented at the screen top (that is, Chinese character output hurdle (40A)) of display part (40), and if press numerical key 1 continuous 2 times, then demonstration " C ".If continuous 3 times are pressed 1 demonstration of numerical key " A ", if continuous 4 times are pressed 1 demonstration " B " once more of numerical key.

Promptly, after pressing 1 continuously, " B ", " C ", " A ", " B ", " C ", " A " ... go up at display part (40) successively and show, when required English alphabet occurs, the enter key of pressing other text button or setting in addition, after perhaps passing through certain hour, current selecteed English alphabet is imported into mobile communication terminal.

By operating after other function key enters English/Chinese character input mode, by to be assigned to letter on each numerical key and capitiform feature make up import in the national language Chinese character.The user by with English input pattern under the identical method of input process of English alphabet, input is assigned to English alphabet or the capitiform feature on each numerical key.Receive the device of the key data imported, promptly the data-signal imported by automatic differentiation of control part (20) is that the input signal of English alphabet or the input signal of capitiform feature are accepted this input.

For example, by behind the numerical key 2 next time, be assigned to the 1st English alphabet " D " or first capitiform Feature Recognition lettering on the numerical key 2 under the Chinese character input mode On display part, show, and press continuously 2 numerical keys, 2 backs show " F " or

Press continuously 3 numerical keys, 2 backs show " E " or

Press continuously show once more behind 4 numerical keys 2 " D " or

That is, press numerical key 2 continuously after, " D ", " F ", " E ", " D ", " F ", " E " ... perhaps

On display part, show successively, when required English alphabet or capitiform Feature Recognition lettering occur, the enter key of pressing other text button or setting in addition, after perhaps passing through certain hour, current selecteed English alphabet and capitiform Feature Recognition lettering are imported into mobile communication terminal.

For example, when input " FE ",, therefore when importing continuously, must distinguish input first key data " F " and second key data " E " because " F " and " E " is assigned on the same key.Signal distinguishing between such 2 key data is identical with general character input method, can utilize stand-by time, also can give * in addition or # key equisignal sector branch function is used, and also can utilize the direction shift key to make the input position of signal move to the next one.

In the present invention, the data-signal that control part (20) is imported by automatic differentiation is the input signal or the input signal of capitiform feature of English alphabet and accepts this input, at this moment, the initial key data of importing is automatically recognized and is that it is the capitiform feature of going ahead of the rest that first letter of the Chinese phonetic alphabet, the key data of second input are automatically recognized.In addition, input is in advance after the capitiform feature, after the key data of importing by automatic differentiation is the selection signal or the input signal of follow-up capitiform feature of Chinese character, accepts this input, and such differentiation process is detailed description more later on.

On the other hand, be assigned to the English alphabet on each numerical key, its mutual alignment is all variable, and is assigned under the condition of numerical key 1～6 at the identification lettering with " determining ", " river ", " meter ", " he ", " silk ", and capitiform feature mutual alignment is also all variable.

But therefrom the angle of national language Chinese character input speed is seen, we can say that preferably that frequency of utilization is high more capitiform feature and English alphabet are assigned on the few more position of key signals number, and what frequency of utilization was low more is assigned on the many more positions of key signals number.

The distribution of English alphabet is for example on the dialing keyboard of Fig. 4: after at first in

alphabetical order

2 or 3 English alphabets being assigned on 10 numerical keys of from 1 to 0, with the low-down A of I, V, U and frequency of utilization, these 6 letters of E, O and the sequence independence that do not use in the English alphabet that is assigned on the same key as first letter of the Chinese phonetic alphabet to be assigned to the key signals number be on 3 the position.This distribution method of English alphabet can be with first letter of the Chinese phonetic alphabet of most of Chinese Language words with the input of the key signals number below 2 times, thereby has improved the speed of literal input.

On the other hand, identification lettering With Be assigned to simultaneously on the numerical key 1, With Be assigned to simultaneously on the numerical key 1.This means that capitiform feature " water " and " ending " are imported simultaneously when pressing 2 numerical keys 1 continuously.This be because input commonly used 3, during 500 Chinese characters, the frequency of utilization of capitiform feature " water " and " ending " is low and number corresponding Chinese character is few, therefore in the time of will importing Chinese character with capitiform feature " water ", even on display part (40), show to have capitiform feature " water " and have the Chinese character that the capitiform feature " is ended " simultaneously, also be easy to find required Chinese character.Input function is equally applicable to by the 3rd identification lettering that is assigned on the numerical key 1 in the time of such With Capitiform feature " " and " ear " and be assigned to identification lettering on the numerical key 0

With

Capitiform feature " power " and " ring ".

Followingly Chinese character input of the present invention is described with reference to Fig. 5.

In step S11, user's operation is used for the function key of setting key input media (10) pattern, enters English/Chinese character input mode.

In step S12, after first alphabetical pairing numerical key of the Chinese phonetic alphabet of the required Chinese character that the user will be imported is pressed pre-determined number, key input apparatus (10) generates the corresponding key data of numerical key with the pre-determined number that is pressed, and is sent to control part (20).At this moment, control part (20) is identified as the key data that sends for the first time first letter of the Chinese phonetic alphabet of required Chinese character automatically.

In step S13, after the corresponding numerical key of capitiform feature of the required Chinese character that will will import with the user was pressed pre-determined number, key input apparatus (10) generated and the corresponding key data of numerical key of the pre-determined number that is pressed, and is sent to control part (20).At this moment, control part (20) key data that second pass is sent here is identified as the capitiform feature in advance of required Chinese character automatically.

In step S14, the database in control part (20) search memory (30), extract out satisfy simultaneously with at first letter of the Chinese phonetic alphabet of step S12 and S13 input and Chinese character of the corresponding key data of capitiform feature of going ahead of the rest.Satisfy at the same time step S12 and S13 input the Chinese phonetic alphabet first letter and in advance in Chinese character of capitiform feature, both had Chinese character with single capitiform feature, also have Chinese character with a plurality of capitiform features.Control part (20) is only isolated the Chinese character that has single capitiform feature in the middle of these Chinese characters, gives priority ranking according to frequency of utilization, and begins to be arranged in order from the high Chinese character of priority ranking, forms the Chinese character group by predetermined number-for example maximum 6 Chinese characters constitute.

In step S15, control part (20) is sent to display part (40) with the Chinese character group in advance as the high Chinese character group of priority ranking in the Chinese character group that generates among the step S14, and selects the numbering arrangement to be presented at Chinese character with Chinese character the Chinese character of this Chinese character group and arrange in the hurdle (40B).At this moment, have under the situation of follow-up Chinese character group, arrange demonstration arrow mark () in the hurdle (40B) at Chinese character.In Chinese input unit (10), can set other function key or direction shift key etc. as arrow mark () assignment key.

In step S16, the user has selected under the situation of certain key, and Chinese input unit (10) generates the key data corresponding with selected key and is sent to control part (20).Control part (20) judges that whether selecteed key is arrow mark () assignment key, if user-selected key is arrow mark () assignment key, then advances to step S17, otherwise advances to step S18.

In step S17, after control part (20) is sent to display part (40) with follow-up Chinese character group, selects numbering to arrange with Chinese character the Chinese character of this Chinese character group and be presented in the Chinese character arrangement hurdle (40B), and return step S16.In this case, if there is follow-up Chinese character group, then also arrange demonstration arrow mark () in the hurdle (40B) at Chinese character.

In step S18, the key that control part (20) is selected user among the step S16 is identified as in the middle of the enter key of Chinese character options button or follow-up capitiform feature automatically.If it is that signal selected in Chinese character that control part (20) is judged this key data, then advances to step S23, otherwise advance to step S19.

In step S19, after the key that control part (20) is selected user among the step S16 is identified as the follow-up capitiform feature of required Chinese character automatically, retrieval and extract the Chinese character that satisfies the follow-up capitiform feature that identifies among the step S16 simultaneously (that is, to first letter of the Chinese phonetic alphabet of input, the Chinese character that all satisfies of capitiform feature and follow-up capitiform feature in advance) out in the Chinese character that step S14 extracts out.Control part (20) will be given the Chinese character of extraction according to the priority ranking of frequency of utilization, and begin to be arranged in order from the high Chinese character of priority ranking, thereby form the Chinese character group by predetermined number-for example maximum 6 Chinese characters constitute.

In step S20, control part (20) will be in the Chinese character group that step S19 generates, Chinese character group in advance as the high Chinese character group of priority ranking is sent to display part (40), and selects the numbering arrangement to be presented at Chinese character with Chinese character the Chinese character of this Chinese character group and arrange in the hurdle (40B).At this moment, exist under the situation of follow-up Chinese character group, arrange demonstration arrow mark () in the hurdle (40B) at Chinese character.

In step S21, the user has selected under the situation of certain key, and Chinese input unit (10) generates the key data corresponding with selected key and is sent to control part (20).Control part (20) judges that whether selected key is arrow mark () assignment key, if user-selected key is arrow mark () assignment key, then advances to step S22, otherwise advances to step S23.

In step S22, control part (20) is sent to display part (40) with follow-up Chinese character group, and selects the numbering arrangement to be presented at Chinese character with Chinese character the Chinese character of this Chinese character group and arrange in the hurdle (40B), return step S21 then.In this case, if there is follow-up Chinese character group, also arrange demonstration arrow mark () in the hurdle (40B) at Chinese character.

In step S23, control part (20) will be presented at the Chinese character output hurdle (40A) of display part (40) with the user-selected corresponding Chinese character of Chinese character options button.

In order to be more readily understood the middle national language Chinese character input output method of the invention described above, with reference to the actual input example of Fig. 4～Fig. 6 b explanation to several Chinese characters.Following one side is with reference to above-mentioned Chinese character input output method, Yi Bian the input output method of each Chinese character is described.

I. extract the Chinese character example of a capitiform feature out: star

" star " is first letter of the Chinese phonetic alphabet is characterized as the 17th capitiform feature " mouth " for " X ", its capitiform single capitiform feature Chinese character.

In step S11, user operation is used for entering English/Chinese character input mode after the function key of pattern of setting key input media (10).

In step S12, the user is continuous press the numerical key 9 of first letter " X " of the Chinese phonetic alphabet that is assigned " star " for 2 times after, key input apparatus (10) is sent to control part (20) with the key data of pressing numerical key 9 for continuous 2 times.The key data that control part will as above most begin to send is identified as first alphabetical input signal of the Chinese phonetic alphabet of required Chinese character, and goes up demonstration " X " on the Chinese character output hurdle of display part (40) (40A).

In step S13, the user presses 1 sub-distribution identification lettering as the 17th capitiform feature " mouth " of the capitiform feature of " star "

Numerical key 8.The key data that key input apparatus (10) will be pressed 1 numerical key 8 is sent to control part (20).Control part (20) will be as above the key data sent here of second pass be identified as the capitiform feature in advance of required Chinese character, and go up on the Chinese character output hurdle of display part (40) (40A) and to show

In step S14, behind the database in control part (20) search memory (30), first letter of the Chinese phonetic alphabet is characterized as the Chinese character extraction of " mouth " for " X " and the capitiform of going ahead of the rest.First letter of the Chinese phonetic alphabet for " X " and in advance capitiform be characterized as in the middle of the Chinese character of " mouth ", both had the Chinese character that has single capitiform feature as the required Chinese character " star " that will import now, also the Chinese character of existence with a plurality of capitiform features.Control part (20) is only isolated the Chinese character that has single capitiform feature in the middle of these Chinese characters, gives priority ranking according to frequency of utilization, and begins to be arranged in order from the high Chinese character of priority ranking, thereby forms the Chinese character group that is made of 6 Chinese characters at most.

In step S15, control part (20) is sent to display part (40) with the Chinese character group in advance as the high Chinese character group of priority ranking in the Chinese character group that generates among the step S14, and the Chinese character that will organize selects the numbering arrangement to be presented in the Chinese character arrangement hurdle (40B) with Chinese character.At this moment, shown in Fig. 6 a, as the capitiform Feature Recognition lettering of " star " Be presented in the Chinese character output hurdle (40A), and maximum 6 Chinese characters that constitute Chinese character group in advance with from numerical key 1 to numerical key 6 Chinese character select numbering to arrange to be presented at Chinese character to arrange the hurdle (40B).The Chinese character of extracting out surpasses under 6 the situation (promptly constituting the situation of the Chinese character group more than 2), and arrow mark () is presented at Chinese character and arranges in the hurdle (40B).

In step S16, with reference to Fig. 6 a, " star " is assigned on the Chinese character selection numbering 3 in Chinese character arrangement hurdle (40B), so the user presses Chinese character selection numbering (being numerical key) 31 time.Key input apparatus (10) generates the key data when pressing 1 numerical key 3 and is sent to control part (20).The key data that control part (20) affirmation sends is not specified arrow mark () afterwards, advances to step S18.

But, if being presented at Chinese character, " star " do not arrange in the hurdle (40B), then the user selects arrow mark ().After control part (20) is confirmed the key of the particular key appointment arrow mark () that the user presses, and advance to step S17.

In step S17, after control part (20) is sent to display part (40) with follow-up Chinese character group, selects numbering to arrange to be presented at Chinese character to arrange in the hurdle (40B) with Chinese character the Chinese character of this group and return step S16.In this case, if there is follow-up Chinese character group, just arrange demonstration arrow mark () in the hurdle (40B) at Chinese character.

In step S18, control part (20) is identified as Chinese character with the key data that sends among the step S16 and selects in the middle of the input signal of signal or the 2nd capitiform feature one.If it is that signal selected in Chinese character that control part (20) is judged this key data, then advances to step S23, otherwise advance to step S19.

When the user presses 1 numerical key 3, first capitiform feature as correspondence, what be assigned with is the 2nd capitiform feature " river ", but according to capitiform feature extracting method of the present invention, commonly used 3, in 500 Chinese characters, do not exist with the 2nd capitiform feature " river " to be as the Chinese character that follow-up capitiform feature is drawn out of.Therefore, control part (20) will be identified as Chinese character automatically and select signal by the key data that key input apparatus (10) produces, and after advancing to step S23, shown in Fig. 6 b, show required Chinese character " star " in Chinese character output hurdle (40A).

On the other hand, if required Chinese character be not the Chinese phonetic alphabet first letter for " X " and in advance capitiform be characterized as " star " of " mouth ", then the user presses other key except that numerical key 3.The following describes this situation.

Press numerical key 2～6 o'clock of keyboard as shown in Figure 4 respectively 1 time, corresponding capitiform feature " is determined ", " river ", " meter ", " beating " and " silk " all are the capitiform features of going ahead of the rest that can not be used as follow-up capitiform feature.Therefore, in step S16, when pressing 1 certain numerical key in the numerical key 2～6, corresponding capitiform feature is non-existent, so the key data that control part (20) will be corresponding with this numerical key is identified as Chinese character automatically and selects signal.

On the other hand, Chinese character selects numbering to be assigned to numerical key 1～6, but the capitiform feature of correspondence is non-existent when pressing the numerical key 1 of 1 keyboard shown in Figure 4.Promptly, in mobile communication terminal of the present invention, adopted input error prevention function, and the key data of control part (20) when Chinese character is selected to press 1 numerical key 1 in the step (being step S16) is identified as Chinese character automatically and selects signal with the special token (◎) on the numerical key 1 that is assigned to keyboard expression.

In the present embodiment, when in step S14, constituting the Chinese character group, form 1 group, and arrange 6 Chinese characters of demonstration in the hurdle (40B) at the Chinese character of display part (40) with 6 Chinese characters.This is the particular key of specifying arrow mark () in order to operate by the user, makes the Chinese character of desired follow-up Chinese character group show that number of times minimizes, thereby improves as all input speeds of Chinese character.Therefore,, then in the Chinese character arrangement hurdle (40B) of display part (40), only show 5 Chinese characters, can not adopt the input error prevention function of the special token (◎) that is assigned on the numerical key 1 if constitute the Chinese character group with maximum 5 Chinese characters.Certainly, under these circumstances, be assigned among Fig. 4 that the capitiform feature on the numerical key 2～6 " is determined ", " river ", " meter ", " beating " and " silk " be redistributed on the numerical key 1～5.

The particular key that appointment arrow mark () has been described in the present embodiment is the other function key or the direction shift key of key input apparatus (10), but import the key that numbering and follow-up capitiform feature selected in Chinese character so long as not being used to, then can set any key as special other key of specifying arrow mark ().

On the other hand, in step S16, user's Chinese character neither selects Chinese character to select numbering also not select the situation of arrow mark (), promptly press more than 2 times the Any Digit key or press one situation in the middle of other numerical key except numerical key 1～6 and arrow assignment key 1 time, be the situation that the capitiform characteristic information on this numerical key is transfused to that is assigned to, below describe with reference to the input example with Chinese character of a plurality of capitiform features.But, Chinese character with independently a plurality of capitiform features not is identical with single capitiform feature Chinese character with the Chinese characters with 2 capitiform features independent and that repeat mutually, the corresponding capitiform feature that is drawn out of is 1, so its input method is identical with the input method of the Chinese character with single capitiform feature.Therefore, omit explanation to the input method of Chinese character with independently a plurality of capitiform features not and Chinese character with 2 capitiform features independent and that repeat mutually.

II. can extract the Chinese character example of 2 capitiform features out:

" all " be first letter of the Chinese phonetic alphabet for " D ", have a plurality of capitiform features, the i.e. Chinese character of the 15th capitiform feature " ten " and the 20th capitiform feature " people ", these 2 capitiform features are separate, therefore extract the 15th capitiform feature " ten " out as the capitiform feature of going ahead of the rest, extract the 20th capitiform feature " people " out as follow-up capitiform feature.

In step S12, after the user pressed the numerical key 2 of first letter " D " of the Chinese phonetic alphabet that 1 sub-distribution has " all ", the key data when key input apparatus (10) will be pressed 1 numerical key 2 was sent to control part (20).The key data that control part (20) will as above most begin to send is identified as first alphabetical input signal of the Chinese phonetic alphabet of required Chinese character, and goes up demonstration " D " on the Chinese character output hurdle of display part (40) (40A).

In step S13, the user presses the identification lettering of the 15th capitiform feature " ten " of capitiform feature in advance that 2 sub-distribution have conduct " all " continuously

Numerical key 4.Key input apparatus (10) will be pressed 2 key data behind the numerical key 4 continuously and be sent to control part (20).The control part 20 as above key data sent here of second pass is identified as the capitiform feature in advance of required Chinese character, and goes up on the Chinese character output hurdle of display part (40) (40A) and to show

In step S14, behind the database in control part (20) search memory (30), with first letter of the Chinese phonetic alphabet for " D " and have in advance the Chinese character of capitiform feature " ten " and extract out.For " D " and have in the middle of the Chinese character of capitiform feature " ten " in advance, both there had been Chinese character at first letter of the Chinese phonetic alphabet, also had Chinese character with a plurality of capitiform features with single capitiform feature.Control part (20) is only isolated the Chinese character that has single capitiform feature in the middle of these Chinese characters, gives priority ranking according to frequency of utilization, and begins to be arranged in order from the high Chinese character of priority ranking, thereby forms the Chinese character group that is made of 6 Chinese characters at most.

In step S15, control part (20) is sent to display part (40) with the Chinese character group in advance as the high Chinese character group of priority ranking in the Chinese character group that generates among the step S14, and selects the numbering arrangement to be presented at Chinese character with Chinese character the Chinese character of this Chinese character group and arrange in the hurdle (40B).

As the in advance capitiform Feature Recognition lettering of " all " Be presented in the Chinese character output hurdle (40A), and maximum 6 Chinese characters that constitute Chinese character group in advance with from numerical key 1 to numerical key 6 Chinese character select numbering to arrange to be presented at Chinese character to arrange the hurdle (40B).The situation of the Chinese character of extracting out above 6 (promptly, constitute the situation of the Chinese character group more than 2) under, arrow mark () is presented at Chinese character and arranges in the hurdle (40B), and specifies the key of arrow mark () can be set at the other function key of key input apparatus (10) or direction shift key etc.

Input process so far is identical with the input process of above-mentioned single capitiform feature Chinese character, therefore, the Chinese character group that generates in step S14 only is made of the Chinese character with single capitiform feature, thereby does not show corresponding required Chinese character " all " in Chinese character arrangement hurdle (40B).

In step S16, after the user selects particular key, in key input apparatus (10), generate the key data corresponding and be sent to control part (20) with user-selected particular key.But, do not show corresponding Chinese character " all " because arrange in the hurdle (40B), so the user do not press the Chinese character options button, and presses other key at Chinese character.That is, the user can select to specify the key of arrow mark () to continue to check next group Chinese character, considers that this Chinese character " all " is the Chinese character with 2 capitiform features, and also can press 3 sub-distribution fast has the identification lettering Key 3 import the follow-up capitiform feature " people " of " all ".

Control part (20) judges that what key the key that the user selects is.If the user has selected arrow mark () assignment key, then advance to step S17 after, control part (20) is sent to display part (40) with follow-up Chinese character group, and the Chinese character of this Chinese character group is selected numbering to arrange to be presented at Chinese character to arrange in the hurdle (40B) with Chinese character.On the contrary, if do not select to specify the key of arrow mark (), then advance to step S18.

In step S19, control part (20) is identified as follow-up capitiform feature with the key data that sends and is transfused to.

In step S20, the Chinese character that comprises follow-up capitiform feature " people " that control part (20) retrieval and extracting out from the Chinese character that step S14 extracts out identifies among the step S19 (promptly, satisfy the Chinese character of first letter " D " of the Chinese phonetic alphabet, the capitiform feature " ten " of going ahead of the rest and follow-up capitiform feature " people " simultaneously), give priority ranking according to frequency of utilization, and begin to be arranged in order from the high Chinese character of priority ranking and constitute the Chinese character group, and each group is by predetermined number, and for example maximum 6 Chinese characters constitute.Control part (20) with in the Chinese character group that generates as the Chinese character group in advance of the high Chinese character group of priority ranking, be sent to display part (40), and the Chinese character of this Chinese character group selected numbering to arrange to be presented at Chinese character to arrange in the hurdle (40B) with Chinese character.At this moment, show the capitiform feature " ten " of input so far and the identification lettering of " people " in the Chinese character output hurdle (40A) of display part (40) successively

With

In step S21, after the user had selected particular key, key input apparatus (10) generated the key data corresponding with selected key, is sent to control part (20).Control part (20) judges whether this particular key is the key of specifying arrow mark (), if arrow mark () assignment key, then advance to step S22, and after follow-up Chinese character group is sent to display part (40), selecting numbering to arrange with Chinese character the Chinese character of this Chinese character group is presented in the Chinese character arrangement hurdle (40B), under the situation that is not arrow mark () assignment key, advance to step S23.

In step S23, control part (20) is identified as key user-selected among the step S21 options button of required Chinese character automatically.Promptly, identical with the Chinese character input method of single capitiform feature, pressing numerical key 2～6 o'clock of keyboard as shown in Figure 4 respectively 1 time, because corresponding capitiform feature is all only as capitiform feature in advance, thereby this key data can not be identified as the follow-up capitiform feature of appending.When therefore pressing in the numerical key 2～6 in step S21, the key data that control part (20) will be corresponding with this numerical key is identified as Chinese character automatically and selects signal, and shows required Chinese character " all " in the Chinese character output hurdle of display part (40) (40A).

On the other hand, Chinese character selects numbering to be assigned to numerical key 1～6, but when pressing the numerical key 1 of 1 keyboard shown in Figure 4, corresponding capitiform feature is non-existent.Promptly, when pressing 1 numerical key 1, because the corresponding sign of setting (◎) adopts in order to prevent input error, thereby when pressing 1 numerical key 1 in step S16 and S21, control part (20) is identified as Chinese character automatically with the key data of corresponding numerical key 1 and selects signal.

In the present embodiment, when in step S14 and step S20, constituting the Chinese character group, form 1 Chinese character group, and arrange maximum 6 Chinese characters of demonstration in the hurdle (40B) at the Chinese character of display part (40) with maximum 6 Chinese characters.This is the particular key of specifying arrow mark () in order to operate by the user, makes the Chinese character of desired follow-up Chinese character group show that number of times minimizes, thereby improves as all input speeds of Chinese character.Therefore, if constitute the Chinese character group, then in the Chinese character arrangement hurdle (40B) of display part (40), only show 5 Chinese characters, and can not adopt the input error prevention function of the special token (◎) that is assigned on the numerical key 1 with maximum 5 Chinese characters.Certainly, under these circumstances, be assigned among Fig. 4 that the capitiform feature on the numerical key 2～6 " is determined ", " river ", " meter ", " beating " and " silk " be redistributed on the numerical key 1～5.

Explanation in the present embodiment be that to specify the particular key of arrow mark () be the other function key or the direction shift key of key input apparatus (10), but import the key that numbering or follow-up capitiform feature selected in Chinese character so long as not being used to, then can set any key as the other key of specifying arrow mark ().

For the Chinese characters with 2 capitiform features independent and that repeat mutually with have the independently Chinese character of 3 capitiform features, the corresponding capitiform feature of extraction also is 2, so its input method is identical with the Chinese characters with independent and mutual unduplicated 2 capitiform features.Therefore, omit having Chinese characters independent and 2 capitiform features of repetition mutually and having the independently explanation of the input method of the Chinese character of 3 capitiform features.

More than explanation is that the user knows the Chinese character input method under the situation of first letter of the Chinese phonetic alphabet of wanting the required Chinese character imported at present and capitiform feature.Below the Chinese character input method under the situation of information any 1 in the middle of first letter of the Chinese phonetic alphabet of required Chinese character or the capitiform feature is not known in explanation.

Because there is the situation only know 1 information in the middle of the Chinese phonetic alphabet and the capitiform feature, thereby (for example in key input apparatus of the present invention (10), preestablished as the particular key of unknown message enter key ^*Or # etc.).That is, under the situation of not knowing Chinese phonetic alphabet information, (for example press particular key ^*Or # etc.) the corresponding capitiform feature of back input, under the situation of not knowing the capitiform characteristic information, (for example press particular key behind first letter of the input Chinese phonetic alphabet ^*Or # etc.), in the Chinese character that display part (40) is exported, select the Chinese character of required input to import then.

For example, first letter of the Chinese phonetic alphabet of single capitiform feature Chinese character " star " is " X ", and can extract capitiform feature " mouth " from the radicals by which characters are arranged in traditional Chinese dictionaries on top out.But, under the situation of only knowing the capitiform feature, replace first letter of the Chinese phonetic alphabet (for example to press particular key ^*Or # etc.) after the input, input capitiform feature " mouth ", and only knowing under first alphabetical situation of the Chinese phonetic alphabet that behind first letter " X " of the input Chinese phonetic alphabet, replacement capitiform feature (is for example pressed particular key ^*Or # etc.) input.

Only to select process of importing in the middle of the Chinese phonetic alphabet and the capitiform feature as mentioned above in order more easily understanding, the input process of single capitiform feature Chinese character " star " to be described below in more detail.

1. do not know the example under the Chinese phonetic alphabet information state: star

The capitiform of knowing " star " under this situation is characterized as the 17th capitiform feature " mouth ".

In step S12, the user press particular key ( ^*Or # etc.).Key input apparatus (10) generates with the corresponding key data of particular key and is sent to control part (20).Control part (20) though will be identified as Chinese phonetic alphabet input signal by the key data that key input apparatus (10) begin to send most because at present the particular key of input ( ^*Or # etc.) do not distribute the Chinese phonetic alphabet on, therefore it is identified as unknown Chinese phonetic alphabet signal.

In step S13, the user presses 1 sub-distribution identification lettering as the 17th capitiform feature " mouth " of the capitiform feature of " star " Numerical key 8.Key data when key input apparatus (10) will be pressed 1 numerical key 8 is sent to control part (20).Control part (20) will be as above the key data sent here of second pass be identified as the capitiform feature in advance of required Chinese character, and go up on the Chinese character output hurdle of display part (40) (40A) and to show

In step S14, behind the database in control part (20) search memory (30), with the capitiform of going ahead of the rest is characterized as the Chinese character extraction of " mouth " with first letter of the Chinese phonetic alphabet is irrelevant in the single capitiform feature Chinese character, give priority ranking according to frequency of utilization, and begin to be arranged in order, thereby form the Chinese character groups that constitute by 6 Chinese characters at most from the high Chinese character of priority ranking.

In step S15, control part (20) is sent to display part (40) with the Chinese character group in advance as the high Chinese character group of priority ranking in the Chinese character group that generates among the step S14, and selects the numbering arrangement to be presented at Chinese character with Chinese character the Chinese character of this Chinese character group and arrange in the hurdle (40B).That is the identification lettering of the capitiform feature " mouth " of " star ",

Be presented in the Chinese character output hurdle (40A), and maximum 6 Chinese characters that constitute Chinese character group are in advance selected numbering to arrange to be presented at Chinese character to arrange the hurdle (40B) with from 1 to 6 Chinese character.The Chinese character of extracting out surpasses under 6 the situation (promptly constituting the situation of the Chinese character group more than 2), and arrow mark () is presented at Chinese character and arranges in the hurdle (40B).Later Chinese character input process is compared with step S16 in aforementioned " star " input process, and its principle or process are identical, therefore omits explanation.

On the other hand, not to extract the Chinese character of single capitiform feature out but extract out under the situation of Chinese character of a plurality of capitiform features, input is imported follow-up capitiform feature after the capitiform feature in advance as previously mentioned, but if this moment is the follow-up capitiform feature of normal input, then control part (20) will both meet in advance that capitiform feature " mouth " meets also thereafter that the Chinese character of the follow-up capitiform feature of input is extracted out and the composition group after be sent to display part (40), and select numbering to arrange with Chinese character the Chinese character of this Chinese character group to be presented in the Chinese character arrangement hurdle (40B).

But, after importing special keys once more as follow-up capitiform feature input signal, control part (20) will have in the Chinese character of a plurality of capitiform features with the Chinese phonetic alphabet and follow-up capitiform feature irrelevant and in advance the capitiform Chinese character that is characterized as " mouth " extract out and the composition group after be sent to display part (40), and select numbering to arrange demonstration with Chinese character the Chinese character of this Chinese character group.

The later process of step S17 compares in input process of later Chinese character input process and aforementioned " all ", and its principle is identical with process, therefore omits explanation.

2. do not know the situation of capitiform characteristic information: star

First letter of knowing the Chinese phonetic alphabet of " star " under this situation is " X ".

In step S12, the user presses numerical key 9 continuous 2 times.Key data when key input apparatus (10) is pressed numerical key 9 with continuous 2 times is sent to control part (20).Control part (20) will be identified as first alphabetical input signal of the Chinese phonetic alphabet of required Chinese character automatically by first key data that key input apparatus (10) begin to send most.When pressing the numerical key 9 of 2 keyboards,, therefore go up the demonstration Chinese phonetic alphabet " X " on the Chinese character output hurdle of display part (40) (40A) because corresponding letter is " X ".

In step S13, the user (for example presses particular key ^*Or # etc.).Key input apparatus (10) generates with the corresponding key data of particular key and is sent to control part (20).Control part (20) will be though will be identified as the input signal of capitiform feature in advance by the key data that key input apparatus (10) second pass is sent here automatically, but, therefore it is identified as unknown capitiform characteristic signal because do not distribute the capitiform feature on the present particular key of importing.

In step S14, behind the database of control part (20) search memory (30), with Chinese character that first letter of the Chinese phonetic alphabet is " X " is extracted out with the capitiform feature of going ahead of the rest is irrelevant in the single capitiform feature Chinese character, give priority ranking according to frequency of utilization, and begin to be arranged in order, thereby form the Chinese character groups that constitute by 6 Chinese characters at most from the high Chinese character of priority ranking.

In step S15, control part (20) is sent to display part (40) with the Chinese character group in advance as the high Chinese character group of priority ranking in the Chinese character group that generates among the step S14, and selects the numbering arrangement to be presented at Chinese character with Chinese character the Chinese character of this Chinese character group and arrange in the hurdle (40B).That is, as the identification lettering of the capitiform feature " mouth " of " star "

Be presented in the Chinese character output hurdle (40A), and maximum 6 Chinese characters that constitute Chinese character group are in advance selected numbering to arrange to be presented at Chinese character to arrange the hurdle (40B) with from 1 to 6 Chinese character.The Chinese character of extracting out surpasses under 6 the situation (promptly constituting the situation of the Chinese character group more than 2), in be presented at Chinese character arrangement hurdle (40B) by arrow mark ().The later process of step S16 compares in later Chinese character input process and aforementioned " star " input process, and its principle is identical with process, therefore omits explanation.

On the other hand, not to extract the Chinese character of single capitiform feature out but extract out under the situation of Chinese character of a plurality of capitiform features, import follow-up capitiform feature after importing the special keys of representing the capitiform feature of going ahead of the rest, but after the follow-up capitiform feature of normal input this moment, control part (20) will both meet that Chinese character that the Chinese phonetic alphabet " X " also meets the follow-up capitiform feature of back input is extracted out and the composition group after be sent to display part (40), and the Chinese character that the Chinese character of this Chinese character group selects numbering to be presented at display part (40) with Chinese character is arranged in the hurdle (40B).But, after importing special keys once more as the input signal of follow-up capitiform feature, control part (20) will have in the middle of the Chinese character of a plurality of capitiform features with in advance and follow-up capitiform feature is irrelevant and the Chinese phonetic alphabet is sent to display part (40) for the Chinese character of " X " after extracting out, and the Chinese character of this Chinese character group selected numbering to arrange to be presented at Chinese character to arrange in the hurdle (40B) with Chinese character.The later process of step S17 is compared in input process of later Chinese character input process and aforementioned " all ", and its principle is identical with process, therefore omits explanation.
