Fig. 1 has illustrated an embodiment that is suitable for keypad according to the present invention.Cellular phone 10 with keypad (can also be other data input devices, as personal digital assistant, seek family machine, wireless telephone, plain old telephone, telecommunication device etc.), it comprises shell 11, keypad 12, display screen 13, display screen 13 has text input state district 14 and screen prompt district 15, but screen prompt district 15 display screen keyboards 16; The numeral of each numerical key correspondence and letter are a kind of optional embodiments in the keypad 12, the also corresponding punctuation mark of key of numeral " 1 ".In addition, keypad also has several function keys, function key 17 (cancel) is " cancel key ", can represent cancellation to last operation, function key 18 (▲) is " alternative key makes progress " or " to the scroll up key ", function key 19 () is " downward alternative key " or " to the scroll down key ", and function key 20 (enter) is " determining key ".In addition numerical key 0, " ^*" key, " # " key also can replace in the function key 17～20 one or several as function key.

The on-screen keyboard of the small digital keyboard correspondence that following embodiment is related all is triplex row three row, and is corresponding one by one according to the numerical key 1～9 on the keypad among key relative position and Fig. 1, as the corresponding numerical key 1 of key that is in first row, first row in the on-screen keyboard.

A kind of embodiment of English input, its one-level key sequence fixedly bond distance is 2.After English alphabet keys is represented in two of activation continuously, show the one-level character string of the key sequence correspondence that these two keys are formed at on-screen keyboard; After activating on the on-screen keyboard certain actual key that meets the one-level character string correspondence that input requires, again according to the weak linkage sequence search of importing later under selected one-level character string catalogue with the corresponding secondary character string of weak linkage sequence.

With reference to accompanying drawing 5A～H, illustrate that with embodiment the present invention is in the application aspect the English input.

Keyboard with Fig. 1 is provided with input English, when continuous input number keyboard 2 and numerical key 3, and numerical key 2 correspondences [a, b, c], numerical key 3 correspondences [d, e, f], character makes up in order on these two keys 9 kinds, i.e. ad, ae, af, bd, be, bf, cd, ce, cf; And have only 5 the beginning parts that can constitute word in these two monograms, promptly belong to effective combination: ad, ae, af, be, ce.In Fig. 3 A, one-level key sequence 23 corresponding these 5 effective one-level character strings, program search one-level key sequence 23 pairing one-level character strings, if be presented at screen in a kind of non-on-screen keyboard mode, it can be a kind of demonstration as Fig. 5 A, a numeral is arranged before each character combination among the figure, represent the numerical key of this character combination correspondence; Preferably take the on-screen keyboard mode to show, as Fig. 5 B, on-screen keyboard is the display mode that certain keyboard shape framework is arranged, and compares Fig. 5 A and wants directly perceived a lot, also is convenient to select character combination.

In Fig. 5 B, there is be can become word in the one-level character string, preferential other one-level character string of be is presented at input text area (if there are a plurality of one-level character strings can become word, behind input number keyboard 2,6, an, am all can become word, and the highest an of frequency of utilization is presented at input text area).

If will import word be, can perhaps, by determining key, promptly finish the input of word be more directly by determining key by the numerical key 7 of the pairing actual keyboard of be in on-screen keyboard; Program can also be added the space behind the word automatically.

If input word add behind the input number keyboard 2,3, points out the numerical key 4 of selecting the ad correspondence according to the on-screen keyboard of Fig. 5 B, input text area demonstration becoming ad, this moment, on-screen keyboard disappeared; When importing the numerical key 3 at d place again, the corresponding secondary character string of weak linkage sequence " 3 " under the ad catalogue in the program search storer, the secondary character string is the remainder that English word removes preceding two letters, the only corresponding secondary character string of weak linkage sequence " 3 " " d ", screen display such as Fig. 5 C again by determining key, promptly finish the add input, the order of whole enter key is " 2,3,4,3, determine key ", totally five keys.Fig. 4 has illustrated the flow process that processor is operated this simple input, and flow process only relates to definite key and significant figure keyboard among the figure, can increase corresponding program on this basis when relating to other keys and increasing other functions.

After selecting the one-level character string, also can show successive character, the secondary character string of program under the ad catalogue follow-up significant character is shown on the key of on-screen keyboard correspondence,, be convenient to find the character that needs follow-up input like this as Fig. 5 D with on-screen keyboard.

Show aspect the one-level character string that at on-screen keyboard alphabetical number that can also word-building is many as the one-level character string, is shown to the remaining digital key position of on-screen keyboard more than 2 stem, can reduce the keystroke number like this, has also reduced polysemy.Behind input number keyboard 2,7, screen prompt such as Fig. 5 E, on-screen keyboard adopts the stealthy display mode of constructing by the mutual alignment relation of character string among the figure, each character string shows with the arrangement mode of actual keyboard, it is corresponding one by one at the relative position of display screen and each the key relative position in the keyboard, determines its pairing key according to the relative position of each character string.Except original one-level character string ap, aq, ar, as, br, cr, app, aqu, three one-level character strings of ass have also been increased.As need input assist, according to the numerical key 3 of Fig. 5 E screen prompt selection ass correspondence, import the numerical key 4,7,8 of word residue stem ist correspondence again, can get assist; Also can select the numerical key 6 of as correspondence, import the numerical key 7,4,7,8 of remaining stem sist correspondence again, also can get assist.

Because increased the selection step of preceding two monograms of word, the number of words of corresponding same weak linkage sequence significantly reduces.When this situation occurring, screen will have prompting.For example after selecting one-level character string " as ", input number keyboard 7 again, screen display such as Fig. 5 F, the viewing area has prompting pattern "  " expression that alternative word is arranged, if can select the ass in input state district by determining key, if by downward alternative key, ass becomes asp, can determine to import word asp by definite key again.

Also can increase high frequency word prompting input mode, include corresponding frequency of utilization information in the storer with the secondary character string.Such as in Fig. 5 B if select the numerical key 6 of af correspondence, program search is under " af " catalogue, all weak linkage sequences with the beginning of the weak linkage sequence of firm generation, owing to do not produce the weak linkage sequence as yet, be that the weak linkage sequence is for blank, so all secondary character strings under program search " af " catalogue, after using the highest secondary character string of relative frequency to be shown in catalogue " af " with prompting mode, as Fig. 5 G, wherein " after " of prompting mode demonstration is the highest word of frequency of utilization with the af beginning.Can when input number keyboard 1, can select word after numerical key 1 as the function key of selecting the high frequency word.Under the state of Fig. 5 G, if input number keyboard 4 again, program will be searched under " af " catalogue, secondary character string with all weak linkage sequence correspondences of the weak linkage sequence " 4 " of firm generation beginning, after using the highest " ield " of relative frequency to be presented at " af " with prompting mode, screen prompt such as Fig. 5 H, afield are with the highest word of the frequency of utilization of afg or afi beginning (word of no afh beginning in the dictionary), input number keyboard 1 again, can select afield.

For key, can also under a kind of single character input mode, get rid of polysemy with polysemy.Under single character input mode, activate a key after, on on-screen keyboard, show multiple character corresponding to this key, select corresponding character with key with polysemy.For example numerical key 1 corresponding punctuation mark activates numerical key 1 back and shows as Fig. 6 A, if activate the key that other contain letter, such as numerical key 2, can be as the displayed map of Fig. 6 B, the corresponding lowercase of on-screen keyboard first row, the corresponding capitalization of corresponding numeral 2, the three rows of a middle row's middle position.Under this input pattern, relatively visual pattern need be imported two keys, can make things convenient for the input of name and place name for each alphabetical.

If go the method for polysemy according to general speech level, and arrange the input Chinese phonetic alphabet with the letter on the keyboard among Fig. 1,408 cents have become 219 kinds, and every kind has 6 sounds for a long time, and the selection of sound at this moment is just cumbersome.

One of the present invention is in the better embodiment of input equipment with the keypad, behind preceding two phonetic alphabet place keys of the input Chinese phonetic alphabet, in the screen prompt district, show with the phonetic of the orderly combination beginning of all letters of these two key correspondences, comprised the key of representing phonetic alphabet in the actual key of on-screen keyboard correspondence in the on-screen keyboard mode.Behind the selected phonetic with the on-screen keyboard corresponding keys, the Chinese character that program will search for this phonetic correspondence is shown in the screen prompt district in the mode of on-screen keyboard, then with the shown Chinese character of key selection of on-screen keyboard correspondence.

For phonetic such as a, the e of single-letter, input is a bit different, can determine single-letter phonetic by definite key again behind the key of first single-letter correspondence of input.

Fig. 3 B is a kind of optional data figure of Chinese phonetic alphabet input, and its one-level character string is the Chinese phonetic alphabet, and the secondary character string is a Chinese character.Chinese character can store in order according to the Chinese character relative application frequency, and just frequency is low more, after the position is leaned on more, after also leaning on during demonstration.

Optional QWERTY keyboard with Fig. 1 illustrates this input method in conjunction with the embodiments.

Behind input number keyboard 7,3, program is the corresponding phonetic of search key sequence " 73 " in the one-level key sequence of Fig. 3 B, Search Results is presented on the on-screen keyboard of Fig. 7 A, numerical key 5 according to on-screen keyboard prompting input Pinyin ren correspondence, program will be searched for the corresponding Chinese character of selected phonetic " ren ", be shown to on-screen keyboard then in order, it is the Chinese character of phonetic that the on-screen keyboard prompting becomes with ren, as Fig. 7 B, the following Chinese character that does not show in addition of arrow "  " expression can not show Chinese character by downward alternative key.If, can finish the input of " people " by " people " pairing numerical key 1.

When the phonetic of one-level key sequence correspondence surpassed 9, screen had prompting figure "  ", behind input number keyboard 7,4, showed as Fig. 7 C.When by behind the downward alternative key, show as Fig. 7 D, point out figure "  " expression not show phonetic in addition, before arrow " ▲ " expression phonetic is arranged, use the alternative key that makes progress can show phonetic before; If can select phonetic " Ri " by " Ri " corresponding numerical key 7 again.

The input of this kind phonetic only needs the key at preceding two letter difference places of input Pinyin, and many sounds can be determined phonetic in triple bond.But because the phonetic number of some one-level key sequence correspondence is more, need turns over screen and select phonetic, the sound corresponding as above key sequence " 74 " has 37.Below enumerating two kinds of minimizings selects the sound trouble to improve the preferred embodiment of input efficiency.

In the preferred embodiment, adopt the input method of on-screen keyboard prompting successive character, and in on-screen keyboard, individual characters is shifted, also increase some character combinations.Behind first alphabetical place key of the input Chinese phonetic alphabet, on-screen keyboard has increased by second and the 3rd monogram that constitutes in the more phonetic of phonetic number, also will be as the second alphabetical h displacement of cerebral, i, h in phonetic second letter be not on same key like this, and the position of the key of each monogram, the alphabetical h correspondence of displacement can be transferred mutually.Preferred increasable phonetic second and the 3rd monogram have: hu, ia, ua.A preferred relative position is arranged as Fig. 7 E, and wherein the h as the phonetic second letter is displaced to and numerical key 1 corresponding position, but constant when just the h of initial consonant imports as first letter of phonetic.

After first key of input is such as numerical key 7, screen display such as Fig. 7 E; If will import second letter such as qiao, qian, piao and trigram is the phonetic of ia, can select the numerical key 5 of the ia correspondence shown in Fig. 7 E, afterwards screen display such as Fig. 7 F; Input number keyboard 3 can be determined phonetic qiao; If will import second letter such as shu, shuo, shuang and trigram is the phonetic of ha, can select the numerical key 7 of hu correspondence, afterwards screen display such as Fig. 7 G; If will import second letters such as shi, shao, shang is the phonetic of h, can select " h " corresponding numerical key 1, screen display such as Fig. 7 H afterwards in the on-screen keyboard.

The input of second and the 3rd combination letter and the second alphabetical h displacement input with phonetic all are alternative, input Pinyin shu for example, behind input number keyboard 7, show as Fig. 7 E, both can select (ghi) corresponding numerical key 4, show as Fig. 7 I, only need turn over several screens and just can find phonetic shu; Also can select the corresponding numerical key 1 of displacement " h ", search but also need turn over screen; Can also select " hu " among Fig. 7 E corresponding numerical key 7, this is an import pathway the most efficiently.

Owing to taked the input of alternative second and the 3rd combination letter and the second alphabetical h displacement input, originally the phonetic of one-level key sequence 74 correspondences has been dispersed into four groups, 37 sounds have 30 can show at first screen behind two keys, thereby have improved input efficiency.

The another kind of implementation method that can effectively improve input efficiency be phonetic when input second key, generally be to choose to remove h, head vowel i in the cerebral and residue letter or the monogram of u in the phonetic, these letters and monogram are shown on the on-screen keyboard.The on-screen keyboard of preferred selective phonetic second key is shown in Fig. 8 A, wherein ^*An represents nan, ian, corresponding numerical key 1 " ^*An " and " in " of corresponding numerical key 7 do not remove head vowel u, i, be the exception.

Be understood to the Two bors d's oeuveres input from another angle, initial consonant zh, sh, ch respectively with z, s, c letter place key as its enter key, more than 30 simple or compound vowel of a Chinese syllable is divided into nine groups by rule, mainly be to save the letter that obtains behind u, i in the simple or compound vowel of a Chinese syllable and the g or monogram as the simple or compound vowel of a Chinese syllable characteristic letter, with the enter key of simple or compound vowel of a Chinese syllable characteristic letter place key as simple or compound vowel of a Chinese syllable.Wherein, ui, iu are the abbreviations of uei, iou.In the Chinese patent (number of patent application 00109618.4) more detailed narration is arranged.Table 1 is every group of simple or compound vowel of a Chinese syllable characteristic letter and corresponding simple or compound vowel of a Chinese syllable.

Can take multipath input for some special simple or compound vowel of a Chinese syllable, can belong to feature simple or compound vowel of a Chinese syllable letter as simple or compound vowel of a Chinese syllable ui is u or i or e three groups, and second key that promptly contains the phonetic of simple or compound vowel of a Chinese syllable ui can have three kinds of selections, and can find corresponding phonetic.

If need this sound of input ren, import the pairing numerical key 7 of r earlier, press Fig. 8 A prompting again and select the corresponding numerical key 7 of feature simple or compound vowel of a Chinese syllable letter " en ", the phonetic that obtains Fig. 8 B is selected prompting, the corresponding numerical key 7 of choosing " ren " can be selected phonetic " ren ", and promptly the numerical key of the input of phonetic " ren " is " 7,7,7 " in proper order.If will import this sound of zhuang, the pairing numerical key 9 of input z is pressed Fig. 8 A prompting again and is selected feature simple or compound vowel of a Chinese syllable letter earlier ^*The numerical key 1 of an correspondence, the phonetic that obtains Fig. 8 C is selected prompting, and the corresponding numerical key 6 of choosing " zhuang " can be selected phonetic " zhuang ", and promptly the input number keyboard of phonetic " zhuang " is " 9,1,6 " in proper order.

This Two bors d's oeuveres input has significantly reduced turns over the trouble that screen selects sound, because having only tens sounds need turn over screen, search more than 400 sound, overwhelming majority phonetic all can be finished input in triple bond, and general computer 26 key all-phonetic input methods on average are each sound of 4 keys (comprising definite key).This Two bors d's oeuveres also is convenient to the error correction of southern sound, all the same as two keys before cerebral and the corresponding non-cerebral, preceding two keys of back nasal sound and corresponding non-back nasal sound too, like this when the phonetic of finding to come because of southern vocal cores is selected mistake, can select step as long as the last operation of cancellation can be got back to phonetic, and not need to cancel whole phonetic inputs.

The Chinese phonetic script replaces Chinese phonetic alphabet or monogram also can finish above phonetic input and Two bors d's oeuveres input, change phonetic alphabet or monogram into the corresponding Chinese phonetic script or the simple or compound vowel of a Chinese syllable characteristic letter is replaced with the corresponding Chinese phonetic script, and the classification of corresponding demonstration and simple or compound vowel of a Chinese syllable revised a little, can finish the input of Chinese character with above similar step.

In two methods of Chinese-character stroke that the present invention lifted input, the parts of Chinese character are as the one-level character string, and Chinese character is as the secondary character string, the stroke classification of Chinese character, and the corresponding key of one or more strokes.After the input method of the first sum of limiting-members of Chinese character was input the first sum of picture pairing key, the Hanzi component parts of choosing with the corresponding stroke beginning of this key institute as for the election were shown on the on-screen keyboard, and second key will be the selection Hanzi component.The input method of preceding two the stroke key limiting-members of Chinese character is after importing two keys of preceding two the stroke correspondences of Chinese character continuously, choose with these two keys the Hanzi component parts as for the election of corresponding stroke beginning be shown on the on-screen keyboard, triple bond will be to select Hanzi component, select Hanzi component preferably to follow and get big priority principle, promptly preferential selection comprises the maximum parts of stroke.In the follow-up stroke input after selecting Hanzi component multiple screen prompt and keyboard word selection mode are arranged.

Input method below in conjunction with a two-stroke key limiting-members before the Chinese character more than the preferred embodiment explanation.Among this embodiment, stroke is by five kinds of stroke classifications of standard, and these five kinds of pairing strokes of stroke are as shown in table 2 below:

Five kinds of stroke classifications of table 2

This five classes stroke can be any in the distribution of keyboard, wherein a kind of preferred distribution scheme such as Fig. 9 A at numeric keypad.Behind two keys of preceding two correspondences of continuous activation Chinese character, program will be searched for the pairing parts of key sequence of this two key and will be shown on the on-screen keyboard, for ease of the judgement and the selection of Hanzi component, and one two at most corresponding nine parts of key sequence in this preference.For the efficient that reduces the Chinese character information storage capacity and improve demonstration and word selection, will take to get big priority principle in this embodiment.

For example behind input number keyboard 4,5, its screen display such as Fig. 9 B, " Pie one " in the on-screen keyboard on the numerical key 1 expression does not comprise other eight parts and is that to cast aside " Pie " and second be the parts of horizontal " " with the first stroke, waits preceding two parts of Chinese character to represent with " Pie one " as " hair, hand ".According to getting big priority principle, alternative pack " Jin " rather than less parts " " answered in " steel " word; In like manner, alternative pack " standing grain " answered in Chinese character such as " with, perfume (or spice) ", rather than numerical key 1 corresponding components " Pie one " or numerical key 3 corresponding components " thousand ".

After selecting parts " standing grain ", program can become word " standing grain " to be shown in the input state district as the acquiescence Chinese character, and represent to give tacit consent to Chinese character (when when determining key acquiring a following stroke dotted line under it, dotted line disappears, " standing grain " word is to determine that form is input in the sentence), the Chinese character of while program search " standing grain " word parts correspondence, from a follow-up Chinese character, choose for perpendicular " Shu " use relative frequency the highest " with " word is presented at the screen position of stroke " Shu " key correspondence as stroke implication Chinese character, in the same way that relative frequency is the highest " saturating; as to claim; scale; autumn " four words be presented at respectively stroke "

, Pie,, Dian " corresponding on-screen keyboard position; the Chinese character that starts of " standing grain " word parts of search except that above five Chinese characters again; the Chinese character that relative frequency is high is shown on the remaining key of other on-screen keyboard position as non-stroke implication Chinese character, finally screen display such as Fig. 9 C.

If the numerical key 7 of input " journey " word correspondence, program as the acquiescence Chinese character, by after determining key, are promptly finished the input of " journey " with " journey " word again.If input " with " numerical key 2 of word correspondence, program will " with " word as the acquiescence word, search for Chinese character simultaneously with " standing grain+Shu " beginning, from a follow-up Chinese character, choose the screen position of using the highest " profit " word of relative frequency to be presented at stroke " Shu " key correspondence for perpendicular " Shu ", in the same way with relative frequency the highest " with, second, slightly " three words be presented at respectively stroke " , Pie, Dian " corresponding on-screen keyboard position (stroke " " does not have corresponding Chinese character); the Chinese character that starts of " standing grain+Shu " of search except that above four Chinese characters again; the Chinese character that relative frequency is high is shown on the remaining key of other on-screen keyboard position, finally screen display such as Fig. 9 D.According to Fig. 9 D, select " profit " corresponding numerical key 2 after, screen display such as Fig. 9 E, have only " profit, plough, pears " three words with " standing grain+Shu+Shu " beginning this moment, " profit " is the acquiescence Chinese character, can finish the input of " profit " word by definite key.

In the input method of the first sum of limiting-members of Chinese character, first key of Chinese character is represented the first sum of of Chinese character, and the first sum of can be single, also can be the combination of a plurality of strokes, can also be the combination of stroke and font; In the Chinese character input process, first key input back on-screen keyboard shows the parts with the first sum of beginning, and second key will be selected corresponding component.

A kind of preferred embodiment is attached to font in the stroke, is divided into following 9 kinds the first sum of:

Table 3

Figure 10 A is above 9 kinds of the first sum of a kind of preferred distribution at keyboard that comprise font.The preferred components of these nine kinds of the first sum of correspondences such as Figure 10 B～Figure 10 J, these preferred components are arbitrarily in the distribution of keyboard, alternative pack is followed and is got big priority principle.

Behind alternative pack, 2,3,4,5,6 five keys of numerical key are represented " Shu respectively as follow-up basic stroke key Pie one Dian " five basic strokes (not containing font), this five keys are only used in the stroke input of remainder.

In Chinese-character stroke input, multiple input mode is arranged after choosing Hanzi component.With reference to Figure 11 A～G, be example to choose parts " Si " back, illustrate three kinds and show and input mode.For the input method of preceding two the stroke key limiting-members of Chinese character and the input method of the first sum of limiting-members of Chinese character, these three kinds show and input mode all is fit to.A) a kind of on-screen keyboard that do not adopt is according to the follow-up stroke corresponding keys of the Chinese character remainder of constantly importing afterwards

Key sequence, the corresponding Chinese character of screen display, select required Chinese character with alternative key:

For example program search shows by frequency of utilization from high to low successively with the Chinese character of " Si " beginning, and the Chinese character that frequency of utilization is the highest can be used as acquiescence Chinese character (can import this Chinese character by definite key), can instead show in vain to show difference, shows as Figure 11 A.Chinese character by frequency second behind the downward alternative key once will be used as the acquiescence Chinese character, and also with anti-white the demonstration, and by downward alternative key once, then the Chinese character of frequency the 3rd is used as the acquiescence Chinese character, by that analogy again.When selecting successively from the low Chinese character of frequency toward the high Chinese character of frequency from one, the available alternative key that makes progress.Under the situation of Figure 11 A, if the pairing numerical key 5 of input stroke " Dian ", program will be searched for the Chinese character with " Si+Dian " beginning, display result such as Figure 11 B.B) also can still adopt the on-screen keyboard mode, the key corresponding with stroke shows corresponding stroke in the on-screen keyboard, do not have in the on-screen keyboard and the key of follow-up stroke correspondence on show the respective alternative Chinese character, can select this alternative Chinese character with the key that shows the Chinese character correspondence:

For example follow-up basic stroke key (numerical key 2～6) correspondence position of on-screen keyboard shows corresponding stroke, and program search is shown to the highest several Chinese characters of frequency of utilization on other screen key position its display result such as Figure 11 C with the Chinese character of " Si " beginning.If input number keyboard 7 can be finished " line " word input (can determine key) accordingly.Under the situation of Figure 11 C, if the pairing numerical key 6 of input stroke " Dian ", program will be searched for the Chinese character with " Si+Dian " beginning, display result such as Figure 11 D.C) the stroke implication shows and input mode:

The basic stroke key of on-screen keyboard (numerical key 2～6) correspondence position shows the highest Chinese character of relative application frequency that adds the stroke beginning of this key correspondence with " Si ", program is searched for the Chinese character with " Si " beginning except that the shown Chinese character of basic stroke key again, the highest several Chinese characters of relative application frequency are shown on other screen key position its display result such as Figure 11 E.If input number keyboard 7 can be finished " knot " word input (can determine key) accordingly; Under the situation of Figure 11 E, if the pairing numerical key 6 of input stroke " Dian ", program will be acquired the Chinese character " system " of numerical key 6 among the corresponding diagram 11E in input text area as the acquiescence Chinese character, and add following stroke dotted line; The basic stroke key of on-screen keyboard (numerical key 2～6) correspondence position will show the highest Chinese character of frequency of utilization that adds the stroke beginning of this key correspondence with " Si+Dian " again, program is searched for the Chinese character except that above shown Chinese character again, the high several Chinese characters of relative application frequency are shown on other screen key position display result such as Figure 11 F.If by determining key, program will determine that " system " word is the input Chinese character, following stroke of dotted line disappears; If select the numerical key 6 of " contracting " word correspondence, program will " contract " word as the acquiescence Chinese character, and " system " word of input text area will change " contracting " word into, and following stroke dotted line is still arranged, screen display such as Figure 11 G.

On the basis of individual character input, can also be equipped with the phrase association input, in storer, can increase the dictionary relevant with phrase.Program is according to last Chinese character behind the input individual character, and the Chinese character of the formation two-character word group of search dictionary and last Chinese character is listed relevant Chinese character at on-screen keyboard.

With reference to Figure 12 A～C, be input as the input of example explanation phrase association with the first sum of limiting-members stroke of Chinese character.For example behind input " people " word, on-screen keyboard can show the A as Figure 12, and "  " expression also has the individual character that becomes speech with " people " among the figure, and available downward alternative key turns over screen and shows.If activate " " corresponding numerical key 4, program will be added the screen text input field to " " word as the acquiescence Chinese character, and on-screen keyboard will show and numerical key 4 corresponding components simultaneously, show as Figure 12 B.If can determine the input of " " by determining key; If the numerical key 6 that alternative pack " people " is corresponding, on-screen keyboard will show with the Chinese character of " people " parts beginning (the implicit prompting type of stroke shows), show as Figure 12 C.

On-screen keyboard prompting successive character input mode and character implication input mode can also be applied to the computor-keyboard that comprises 26 English keys.Chinese patent (number of patent application is 00109135.2) has been described the input mode that a kind of Two bors d's oeuveres adds Chinese radical, the present invention is transformed it, and point out the prompting of successive character and character implication in conjunction with entering the on-screen keyboard, can reduce learning difficulty and improve input efficiency.The corresponding initial consonant of this input method first key, the corresponding simple or compound vowel of a Chinese syllable of second key, the corresponding radical of triple bond is equivalent to the corresponding initial consonant of each key, simple or compound vowel of a Chinese syllable, three kinds of characters of radical.Can add single vowel sign key rhythm imperial mother for the phonetic of single vowel, as branch "; " corresponding keys.

At the fuzzy sound in non-south, the keyboard setting of preferred initial consonant, simple or compound vowel of a Chinese syllable can be as Figure 13 A (capitalization be an initial consonant, and small letter is a simple or compound vowel of a Chinese syllable).After the initial consonant corresponding keys of a Chinese character of input, on-screen keyboard shows simple or compound vowel of a Chinese syllable such as Figure 13 B, the row of on-screen keyboard be listed as between can be by color the depth of different or color distinguished, the English alphabet of keyboard correspondence can also be shown on the on-screen keyboard.

For ease of finding simple or compound vowel of a Chinese syllable, optional a kind of on-screen keyboard is pointed out the display mode of successive character, and for example behind input initial consonant d, on-screen keyboard can show the C as Figure 13.Behind the key of input simple or compound vowel of a Chinese syllable place, program is searched for relevant Chinese character according to phonetic by the implicit mode of radical and is shown in on-screen keyboard, the representative radical of also pointing out this key correspondence in the upper left corner of the Chinese character place of radical implication key; After for example importing the corresponding keys d and g of Two bors d's oeuveres dan, the Chinese character that program search phonetic " dan " is corresponding is presented at radical implication Chinese character and non-radical implication Chinese character on the on-screen keyboard, as Figure 13 D, has also increased the mode of numerical key selection Chinese character here.For ease of searching Chinese character, can be by frequency of utilization with the Chinese character classification, the depth that the candidate Chinese character of different stage can be by different colours or color or the difference of font or the equal mode of background are distinguished.

The phrase input mode can only be imported the Two bors d's oeuveres of each Chinese character of phrase, for example behind input Two bors d's oeuveres " dan ", triple bond is if select to represent the key F of radical " Rolling " correspondence, first row's numerical key shows that phonetic be " dan " and to represent radical be the Chinese character of " Rolling ", " load " word is placed on numerical key 1 position as the acquiescence Chinese character, the simple or compound vowel of a Chinese syllable that program is also relevant with initial consonant F is presented on the on-screen keyboard its screen display such as Figure 13 E.If press numerical key or definite key (as space bar), program will be interpreted as the individual character input; If press final key, program will be interpreted as the phrase input.Such as, according to Figure 13 E,, then import " brushing lightly " word if press numerical key 2; If press space bar, then " load " word of input default; If press the key U of simple or compound vowel of a Chinese syllable " u " correspondence, the phrase of program search phonetic " danfu " then is as " undertaking ".On the basis of above phrase input, can realize the input of whole sentence, such as, when input " womtwegourgv ", it is " womenweiguozhengguang " that interpretation of programs becomes spelling, corresponding sentence is " we win glory for the motherland ".

More than describe the various embodiments of the present invention in the text input, especially had the Chinese character input aspect of the keypad of key polysemy.The employing of modes such as on-screen keyboard, successive character prompting, character imply has solved the ambiguity problem of key effectively, and provide the numerous approach that improve input efficiency in the mode of intuitive and convenient, the invention enables the convenience and the efficient of text input to be met simultaneously.In the scope that does not exceed essential idea of the present invention, those skilled in the art can do various modifications.
