In addition, display text selection portion 31 is not a necessary formation of the present invention, as long as use handwriting input text handwriting 32, identification can realize the present invention with character and graphic 33, grapholect figure 36 thrins.
And; In this embodiment of the present invention, when having selected grapholect figure 36, except being presented at the literal of confirming on the literal display part 7 through display text selection portion 31; Being presented at that candidate character on the candidate character display part 6 also is in can selected state; If detect any literal that shows on the candidate character display part 6 for being shown in, carried out long pressure (continuing the touch operation of several seconds) or double-clicked (twice continuous touch operation), perhaps it is pulled into the operation of handwriting input display part; Can read the handwriting input literal that is stored in of relevant this candidate character and discern grapholect figure, go forward side by side to exercise and use with database 11.
Literal shows that efferent 28 will be exported and shown by the character and graphic that above-mentioned display text selection portion 31 is selected on handwriting input display part 3.Wherein, display position adjusting portion 29 is presented at handwriting input portion 1 (handwriting input display part 3) last time at the character and graphic of storages such as storage part 23, can regulate its display position.In view of the above, before the character and graphic of the literal confirmed be presented at 3 last times of handwriting input display part, adding the pen input and judging that according to the characteristics of this literal figure this literal figure can become by the left avertence, in by the right avertence, at the bottom of the prefix, word which after considering; By this judged result; If being judged as becomes the other probability of left avertence and this literal figure is moved to the left when high, become the other probability of right avertence when high if be judged as, this literal figure is moved to the right; If be judged as the probability that becomes prefix when high; This literal figure is moved to the top,, this literal figure is moved downwards if be judged as the probability that becomes at the bottom of the word when high.In addition; For example can also by the operation up and down 4 directionkeys will be shown at first central authorities character and graphic move to any direction; Perhaps, also can be through in that this be shown under the state of character and graphic and operation is dragged in its holder that drags to desirable direction regulates display position with finger touch.
Show that the character and graphic that size adjustment 30 adjusting display text selection portions 31 are selected is presented at the handwriting input display part size in 3 last times.In view of the above, through character and graphic being dwindled means such as demonstration, can be easier carry out position adjustments through above-mentioned display position adjusting portion 29.And, regulating display position and character and graphic is carried out move operation simultaneously through display position adjusting portion 29 as previously mentioned, also can this literal figure be diminished.This character and graphic that is shown efferent 28 outputs by literal is read portion 5 through the handwriting input data of handwriting input display part 3 and is read and carry out appropriate display.
After above-mentioned character and graphic is shown; As hereinafter described; Can carry out literal identification by the character and graphic of 10 pairs of demonstrations of handwriting input character recognition portion itself; Perhaps, also can add pen back to the character and graphic that is shown in handwriting input display part 3 and carry out handwriting input as new literal, the character and graphic that is added behind the pen by 10 pairs of handwriting input character recognition portion carries out literal identification.
Fig. 2 representes the workflow that handwriting input identification of the present invention is handled.Handwriting input identification as shown in Figure 2 is handled and is begun (step S1) from handwriting input portion 1, carrying out handwriting input at first, generates identification afterwards with character and graphic (step S2).This processing is to be carried out with character and graphic generation portion 9 by the identification of Fig. 1, promptly the handwriting input person's handwriting 102 shown in Figure 11 (a) is handled, make it to become carry out literal identification easily the identification shown in Figure 11 (b) with character and graphic 103.
Then; Carry out the identification of handwriting input literal and handle (step S3); In step S4; The identification that forms among the step S2 is compared with being stored in the grapholect figure of handwriting input literal identification with each literal in the database 11 with character and graphic 103,, judge whether to exist and the similar literal of handwriting input person's handwriting according to the consistent degree of these two figures.If be judged as here when handwriting input literal identification does not exist in database 11 with the similar literal of handwriting input person's handwriting, then get into step S13, carry out processing can not discern the handwriting input literal of being imported the time shown in Figure 3 as afterwards said.If in step S4, be judged as when handwriting input literal identification exists in database 11 with the similar literal of handwriting input person's handwriting, according to discrimination (consistent degree of figure) order just candidate character be shown in candidate character display part 6 (step S5) according to recognition result.
After obtaining candidate character like this,, these candidate characters temporarily are stored in the candidate character storage part 26 of storage part 23 of Fig. 1 in the present invention in order to carry out the processing of back.
Afterwards; Judge that whether the user has selected to want the literal of importing (step S6) the candidate character on being shown in candidate character display part 6; Judge when having carried out selection; When to be the user through candidate character shown in Figure 1 select indication portion 15 from candidate character, to select any literal through the touchs operation of etc.ing, confirm that literal display process portion 20 is presented at definite literal display part 7 (step S7) with this literal with the sequencing that is determined (in the picture demonstration routine 37 from left to right order).That is, the user has selected to hope " gold " word of input from the candidate character that the candidate character display part shown in Figure 11 (c) 104 shows, should " gold " word just be used as to confirm that literal being shown in shown in Figure 11 (d) confirm literal display part 105.In Figure 11 (d), should " gold " word also be simultaneously to be shown as the literal that is determined at first.
In workflow shown in Figure 2, next step that confirm the literal display process as step S7 handled, and the perhaps processing carried out simultaneously of conduct and step S7 will be stored (step S8) with definite literal is corresponding at the handwriting input person's handwriting of step S1 input etc.Here replace the handwriting input person's handwriting, also can the identification that generate among the step S2 be stored with definite literal is corresponding with character and graphic.Perhaps, also can handwriting input person's handwriting and identification all be stored with character and graphic.The processing of this step S8 is carried out in such a way: the coordinate of each bar line of the handwriting input person's handwriting that shows on the handwriting input display part 3 is stored in the handwriting input character and graphic storage part 24 in the storage part 23 of Fig. 1; Perhaps, the coordinate with each bar line of discerning the character and graphic that generates with character and graphic generation portion 9 is stored in identification with character and graphic storage part 25.
As the subsequent treatment of the stores processor of handwriting input person's handwriting among the step S8 etc., the perhaps processing carried out simultaneously of conduct and step S8 is with confirming that literal stores (step S9) as the handwriting recognition literal according to the sequencing that is determined.Promptly; With being shown in the definite literal of confirming literal display part 7 and the definite literal that is determined in order afterwards as previously mentioned; All be stored in definite literal storage part 27 shown in Figure 1,, as utilize its facility retrieval of carrying out guider etc. so that later on these data are utilized.
As with the processing that step S7～step S8 carries out simultaneously, the candidate character (step S10) that shows on handwriting input person's handwriting that shows on the cancellation handwriting input display part 3 and the candidate character display part 6.In view of the above, with the candidate character that shows on handwriting input person's handwriting 102 shown in Figure 11 (c) and the candidate character display part 104 all cancellations shown in Figure 11 (d).Then, judge whether to carry out the indication (step S11) that handwriting input finishes,, get into step S19 and stop handwriting input if when the user has imported the intention that stops this handwriting input.In contrast,, then get into step S12, as shown in Figure 4ly carry out the 2nd handwriting input that literal is later and handle if in step S11, be judged as when not making the indication that stops handwriting input.
On the other hand; In above-mentioned steps S6, be judged as the user not when 6 kinds of candidate character display parts are selected to hope the literal of input; Judge in step S14 then whether the user has assigned the indication of returning handwriting input; If owing to there are not the reasons such as literal of hoping input in the candidate character, the user has assigned when returning the handwriting input step once more, then returns step S1 and begins to restart to handle from above-mentioned handwriting input.
In step S14, be judged as the user when not assigning the indication of returning handwriting input; Judge then whether the user has assigned the indication of change character input method; When for example having carried out becoming the indication of Chinese pinyin input etc. by handwriting input; Then get into step S16, become the processing of carrying out other indicated input methods.In contrast; If in step S15, be judged as the user when not assigning the indication of conversion character input method; Then getting into step S17 judges whether to have passed through the stipulated time; If be judged as also and then do not return step S6 through the stipulated time, for example the stipulated time is set at 7 seconds, then to the literal through continuing before 7 seconds stipulated times to judge that whether the user has selected hope to import from 6 kinds of candidate character display parts.
If in step S17, be judged as when having passed through the stipulated time; That is, the user had not both had execution in step S6 from 6 kinds of literal of selecting to hope input of candidate character display part, did not have execution in step S14 to assign the indication of returning handwriting input yet; There is not execution in step S15 to assign the indication of conversion character input method yet; After passing through the stipulated time in the case, think that then the user thinks that this handwriting input is imappropriate, irresolute to ensuing operation again; Thereby get into step S18; Cancellation has been imported and has been finished and be presented at the handwriting input person's handwriting on the handwriting input display part 3 and be shown in the candidate character on the candidate character display part 6, returns step S1, begins to handle again from handwriting input once more.
In Fig. 2, carried out and the identical workflow of action shown in Figure 11 of expression prior art, therefore can be considered to shown in Figure 2 is the workflow that comprises prior art.But; Though outwardly like identical with prior art; But handwriting input person's handwriting in step S8 and identification with the storage of character and graphic, can the aspect such as utilize to these data, also have the 2nd handwriting input that literal is later processing illustrated in fig. 4 all different with prior art.
Among Fig. 2 step S13 can not discern the handwriting of input the time processing as shown in Figure 3; At first; User (step S21) is given in the indicated number that will " owing in the handwriting input literal is discerned with database 11, do not exist and the corresponding literal of importing of handwriting input person's handwriting, please import once more ".This processing is carried out as follows: the recognition result of 12 pairs of hand-written input characters of recognition result judging part identification part 10 of Fig. 1 is judged, can not carry out literal identification if be judged as, and then can not carry out above-mentioned demonstration on the display part 13 in identification.
Then, after the indicated number of input again of step S21 finishes, judge whether that for example 4 seconds (step S22) if do not pass through the stipulated time, judges whether the user has assigned the indication (step S23) of returning handwriting input through the stipulated time.Here; If judge that the user does not assign the indication of returning handwriting input; Then get into step S26 and judge whether the user assigns the indication of conversion character input method; When judging that the user has assigned the indication of conversion character input method, for example be transformed into phonetic input etc., then carry out the processing of these other input methods of user's indication.
And, in step S26, be judged as the user when not assigned the indication of conversion character input method, return step S22, continue to judge to import again whether pass through the stipulated time after indicated number finishes.And; In step S23, be judged as the user when having assigned the indication of returning handwriting input; In addition, in above-mentioned steps S22, judge and import again when having passed through the stipulated time after indicated number finishes, get into step S24; The handwriting input person's handwriting that shows on the handwriting input display part that finishes has been imported in cancellation, and the step S1 that returns among Fig. 2 carries out handwriting input (step S25) again.
On the other hand, the 2nd of step S12 the handwriting input that literal is later handled in the workflow as shown in Figure 2, and be as shown in Figure 4, fixed literal (step S31) before at first judging whether to utilize.This judgment processing is carried out as follows: after the literal of previous input has been determined, if the new handwriting input of beginning in handwriting input portion 1 then is judged as and does not utilize the previous literal of confirming and carry out common handwriting input.On the other hand; If detect when confirming that literal selects indication portion 16 to do following operation by selection shown in Figure 1 indication detecting element 8; Then judge to utilize the literal of previous input to carry out the literal input: to being shown in touch operation that the literal of confirming the literal display part carries out, perhaps arbitrarily; Under the state that the literal that is shown in definite literal display part is arbitrarily touched; Operation, is perhaps dragged in its holder of drawing in handwriting input display part 3, through return key 6a shown in Figure 1 is carried out the operation of arbitrary number of times, return the selection indication operation of definite literal that indication portion 17 selects to confirm before the aforesaid operations number of times by handwriting input shown in Figure 1.
In step S31, promptly identical with prior art when being judged as the processing of not carrying out the literal utilization, the step S1 through step S39 gets into Fig. 2 carries out common handwriting input and handles.But as stated, the aspects such as storage of carrying out the handwriting input person's handwriting or discerning with character and graphic of step S8 are the processing different with prior art among Fig. 2.
Concrete example when explanation is judged as in step S31 and utilizes the literal of before having confirmed with reference to Fig. 6.At first, carry out following a series of processing.Shown in Fig. 6 (a); The user with finger tip or nib etc. in the handwriting input portion 41 input the 1st word " gold " the handwriting input person's handwriting after; By handwriting input character recognition portion 10 it being carried out literal identification handles; Be shown on the candidate character display part 42 candidate character of recognition result is as shown in the figure, therefrom select the user to hope the literal of importing " gold ".
As a result, be shown in like Fig. 6 (b) that confirm to show on the literal display part 43 should " gold " word, simultaneously, the candidate character that handwriting input person's handwriting that shows in the cancellation handwriting input portion 1 and candidate character display part 42 show.Afterwards; When the user wants the 1st word " gold " imported as the 2nd word once more (input and the 1st the 2nd word that word is identical); In this embodiment; In order to utilize the literal of previous input, shown in Fig. 6 (b), do to select to being shown in " gold " word of confirming literal display part 43 through touch behaviour.When selection indication detecting element 8 shown in Figure 1 detects this selection operation, in step S31, judge and utilize the previous literal of confirming, get into step S33.
In step S33, read foregoing from confirming the character and graphic of the literal that literal display part 43 is selected.This processing is carried out as follows: as shown in Figure 1; By display text selection portion 31 from handwriting input text handwriting 31, identification with the selection of carrying out character and graphic character and graphic 33 or the grapholect figure 36;, be stored in the handwriting input literal and discern with the character and graphic the character and graphic storage part 25 from the handwriting input text handwriting storage part 24 that is stored in storage part 23, identification with reading the pairing above-mentioned selected character and graphic of above-mentioned selected definite literal in the grapholect figure in the database 11.
Then, showing the above-mentioned character and graphic of in step S33, reading (step S34) in the handwriting input portion 1.This processing is carried out in the following manner: as stated; The literal of Fig. 1 shows that efferent 28 reads the character and graphic that display text selection portion 31 is selected, and when carrying out following adjusting, it is presented at the handwriting input sense data display part 5 of handwriting input display part 3: the adjusting of the display position that is undertaken by display position adjusting portion 29, dwindle adjusting such as display size by what show that size adjustment 30 carries out.
This process result is following: for example shown in Fig. 6 (b), owing to selected to be shown in " gold " word of confirming literal display part 43, shown in Fig. 6 (c), the handwriting input person's handwriting of " gold " word of the previous handwriting input shown in the displayed map 6 (a) in handwriting input portion 41.In the embodiment shown in Fig. 6 (c), add the pen input after considering, the handwriting input person's handwriting of " gold " word is dwindled (with respect to handwriting input time), and show after its top to handwriting input portion 1 is moved.And when having been selected identification with character and graphic 33 by the display text selection portion 31 of Fig. 1, the identification that just in the handwriting input portion 41 of Fig. 6 (c), shows with dashed lines demonstration among Figure 11 (b) with solid line is with character and graphic 103.In addition; When having selected grapholect figure 36 by the display text selection portion 31 of Fig. 1; From handwriting input literal identification grapholect figure, read with storage the database 11 and Fig. 6 (b) in the corresponding grapholect figure of selected " gold " word, and be presented at handwriting input portion 41.
Afterwards, according to the character and graphic that shows in the handwriting input portion 41, candidate character is presented at candidate character display part (step S35) according to discrimination order just.In view of the above; Shown in Fig. 6 (c); When showing the character and graphic of " gold " word in handwriting input portion 1 as previously mentioned, for this character and graphic that is shown, literal identification identical when being undertaken with handwriting input shown in Fig. 6 (a) by handwriting input character recognition portion 10 is handled; And recognition result is shown on the candidate character display part 42, the candidate character that is shown on this candidate character and Fig. 6 (a) is identical.
But; The candidate character display process of on candidate character display part 42, carrying out of carrying out among the step S35; Also can be unlike before said; Carry out literal identification once more by handwriting input character recognition portion 10 and handle, but the corresponding candidate character of handwriting input person's handwriting with " gold " word that will be stored in advance in the candidate character storage part 26 of storage part 23 of Fig. 1 reads, directly be presented on the candidate character display part 42 of Fig. 6 (c).
Then, judge whether from the candidate character that is presented at 42 demonstrations of candidate character display part, to have selected any candidate character (step S36).For example shown in Fig. 6 (c); During the candidate character " gold " that on having selected candidate character display part 42, shows, then get into step S40 shown in Figure 4, selected literal is confirmed as the handwriting input literal; Get into the step S7 of Fig. 2 afterwards, do same processing then as previously mentioned.
In step S36, be judged as when from candidate character, not selecting any candidate character, then be identified as and add the pen input to the figure of display text again that is presented at handwriting input portion 41.That is, shown in Fig. 6 (c), if during the input literal identical with the literal of formerly confirming, directly select this literal of demonstration on the candidate character display part 42, this literal will be determined.Relative with it, when on candidate character display part 42, not carrying out the selection of candidate character, just be estimated as and state Fig. 8 after will carrying out, shown in Figure 9 add an input operation.Add the pen operation at pending these such as step S37.Adding the step S2 that an input operation gets into Fig. 2 after carrying out, the handwriting input as new repeats above-mentioned same processing.
According to the processing of Fig. 4, such shown in can image pattern 6, utilize fixed literal to be easy to carry out the continuous input of same literal, definite operation.But, the invention is not restricted to the situation of the same literal of continuous input shown in Figure 6, also can carry out processing for example shown in Figure 7.
Shown in Fig. 7 (a); After as Fig. 6 (a), having imported " gold " word and having confirmed, again handwriting input " outward " word, carry out literal identification and handle afterwards as recognition result; Candidate character is shown in candidate character display part 42, and candidate character wherein " outward " is in the state of being selected.
According to this selection operation, shown in Fig. 7 (b), on definite literal display part 43, " gold " word then formerly definite and that show shows " outward " word of being imported.Afterwards " gold " of the literal that will then import of user and input at first when word was identical, then as Fig. 7 (b) shown in, the user selected to confirm " gold " word of demonstration on the literal display part 43.
According to this operation, shown in Fig. 7 (c), read the text handwriting of previous handwriting input handwriting input should " gold " word the time and be presented in the handwriting input portion 41.And on candidate character display part 42, show the candidate character that obtains by the recognition result of discerning this literal person's handwriting.Here from a plurality of candidate characters shown in Fig. 7 (c), select the selection action of " gold " word to carry out confirming of input characters according to the user.As a result, shown in Fig. 7 (d), utilize the character and graphic of the literal that input formerly confirms to be easy to then import " gold " word afterwards at " gold ", " outer ".
Fig. 8, Fig. 9 have embodied the processing according to the step S37 of Fig. 4, utilize the character and graphic formerly be determined literal, thereby it is added pen input handwriting input and the different literal of input characters formerly.At first, shown in Fig. 8 (a) and (b), handwriting input " gold " word will carry out selecting candidate character " gold " word it to be imported definite through the user in the result's demonstration and candidate character display part 42 of literal identification to this handwriting input person's handwriting.Operation and contents processing to this are identical with the content shown in Fig. 6 (a) and (b).
According to above-mentioned processing, shown in Fig. 8 (b), on definite literal display part 43, show " gold " word.Afterwards; The user will import shown in Figure 12 (a); By following 2 " gold " words, above during overlapping " prosperous " word that forms of 1 " gold " word, like Fig. 8 (b) if shown in user's " gold " word of having selected definite literal display part 43 to show; The character and graphic (being the handwriting person's handwriting in the example shown in Figure 8) of " gold " word of handwriting input that just will be shown in Fig. 8 (a) is read for 23 kinds from storage part, and is presented in the handwriting input portion 41 of Figure 11 (c).
But; Because under state shown in Fig. 8 (c); Below " gold " word that shows, add relatively difficulty of two " gold " words again, so shown in Fig. 8 (c), upward from the below to the top, slide in handwriting input portion 1 (touch-screen) with finger, the character and graphic of feasible " gold " word that is shown moves to the top.At this moment, the demonstration size adjustment 30 of Fig. 1 with character and graphic to scale (for example 60%) dwindle.Like this; When the display position of the character and graphic of the literal that will before confirm is regulated; Show size adjustment 30 ratio according to the rules; Perhaps, enlarge/dwindle this literal figure automatically, thereby person easy to use more easily adds an input operation for this literal figure is become prescribed level.Here; Method as the display position of the character and graphic of regulating the literal of formerly confirming; Except above-mentioned finger etc. the operation of the enterprising line slip of screen surface, for example can also utilizing, 4 direction buttons or operating grip etc. make character and graphic move to any direction.And; When character and graphic shows shown in Fig. 8 (c); Can also judge that with each grapholect figure of storage in the database 11 this literal figure (" gold ") is high as the probability that the sort of use form (by the left avertence, by the right avertence, at the bottom of the prefix, word) is used according to the identification of retrieval handwriting input literal, then in the handwriting input portion 41 automatically with this literal figure to about about arbitrary direction move.Above-mentionedly utilize handwriting input literal identification to judge with database 11 character and graphic often with which kind of form is used; For example can judge: the character and graphic that is shown is compared with each grapholect figure of storage in the database 11 with the identification of handwriting input literal with following method; If the part consistent with above-mentioned character and graphic often is positioned at the left side of grapholect figure, then is judged as this literal figure and is used so that left avertence is other through regular meeting; If the part consistent with above-mentioned character and graphic often is positioned at the right side of grapholect figure, then is judged as this literal figure and is used so that right avertence is other through regular meeting; If the part consistent with above-mentioned character and graphic often is positioned at the top of grapholect figure, then is judged as this literal figure and is used with prefix through regular meeting; If the part consistent with above-mentioned character and graphic often is positioned at the below of grapholect figure, then is judged as this literal figure and at the bottom of regular meeting is with word, is used.
And the above-mentioned character and graphic that is presented at handwriting input portion done to dwindle when handling when being moved, and can character and graphic be carried out convergent-divergent in varing proportions on transverse direction and longitudinal direction according to the direction that is moved (with the form that is used).If for example character and graphic is being used as a left side (right side) radical when using, make big (little) on (putting) ratio longitudinal direction that contracts of its transverse direction; When if character and graphic uses, make little (greatly) on (putting) ratio longitudinal direction that contracts of its transverse direction at the bottom of being used as prefix, word.
By the aforesaid operations result, the character and graphic of " gold " word moves to the top of handwriting input portion 41 shown in Fig. 8 (d), and is dwindled demonstration.Formed the confession user adds the pen input below " gold " word space in view of the above.Afterwards, shown in Fig. 9 (a), two identical " gold " words of the below handwriting input of the character and graphic of user's " gold " word after being shown processing as previously mentioned.Shown in Fig. 9 (a) is the sight of this input when proceeding to midway.Character and graphic as adding after pen is imported is discerned process result by literal, and shown in Fig. 9 (b), a plurality of candidate characters are shown in candidate character display part 42.The user therefrom selects to hope " prosperous " word of input with reference to this candidate character that is shown.The input of this literal as a result is determined, and is shown in " gold " word demonstration " prosperous " word that then before had been determined on definite literal display part 43 like Fig. 9 (c).
In addition, Fig. 9 (d) has embodied and has selected formerly to be determined and to be shown in the literal of confirming literal display part 43 and make it be presented at the selection indicating means of handwriting input portion 41.When for example importing " prosperous " word shown in above-mentioned Fig. 9 (b); Be presented under the situation of confirming " gold " word on the literal display part 43 when utilization; Can make the character and graphic of " gold " word be shown in the top of handwriting input portion 41 through following manner: under the state of confirming " gold " word on the literal display part 43 with finger touch; Move it to handwriting input portion 41, finger frames out then.That is, dragging literal that operation will select to confirm that literal display part 43 shows through the continuous holder of finger reaches the adjusting of the display position of the character and graphic of this literal has been carried out together.
And; Shown in Fig. 9 (d); Carry out holder same as described above repeatedly and drag operation, will confirm respectively that again " gold " word on the literal display part 43 is drawn to lower left, the lower right of handwriting input portion 41,3 places of character and graphic in handwriting input portion 41 of " gold " word are shown; Can not show the character and graphic of " prosperous " word so yet, and it carried out literal identification handle with hand-written method of adding pen.Input is not " prosperous " again, and during the word that combined by same character and graphic as " gloomy ", " building " etc., the selection indicating means shown in Fig. 9 (d) is very effective.
According to aforesaid various processing, can be with various form embodiment of the present invention.And workflow shown in Figure 5 has embodied and above-mentioned different embodiment.In this embodiment; The 2nd handwriting input that literal is later as the step S12 of Fig. 2 handled; Identical with above-mentioned embodiment shown in Figure 4; The literal of confirming before at first judging whether to utilize (step S51), the unfavorable time spent gets into the step S1 of Fig. 2, carries out new handwriting input (step S62).
In step S51, be judged as when utilizing the literal of before having confirmed; Get into step S53; Judged whether to assign following operation indication: direct input is confirmed and the previous identical literal of confirming of literal, if the aforesaid operations indication has been carried out in judgement, is then got into step S63; To be selected literal and confirm, get into the step S7 of Fig. 2 afterwards as input characters.
That is to say; In the above-mentioned embodiment shown in Figure 4; Even when importing the literal identical once more with the literal of confirming before; Also to make this literal figure temporarily be shown in handwriting input portion, this literal figure is carried out literal identification and show candidate literal, therefrom select then and previous definite identical candidate character of literal.But; In the step S53 of Fig. 5; In order to import once more and when carrying out selection operation at the literal of confirming the literal display part; Through the literal for hope input carry out for example long-time (3 seconds) continue to push (sustained touch) long press operation, or connect the double click operation of pressures (touch) 2 times, send the instruction of importing the literal identical once more with the selection literal, carry out this operation; Need not make from confirming that the literal that the literal display part is selected temporarily is displayed on handwriting input portion, also can be determined it as next input characters.
At step S53; Be judged as when not importing the indication of confirming the literal identical with the previous literal of confirming; Just in step S51, as according to the explanation of Fig. 6～Fig. 9, when only the literal that shows on definite literal display part having been carried out touch operation or drag operation; Then get into step S54, the character and graphic of the selected literal size with regulation is presented on the assigned position of handwriting input portion.At this moment also can make the side shifting of the character and graphic of demonstration, can also make it dwindle demonstration with above-mentioned identical disposal route to the picture of handwriting input portion.Then, by step S55, read the corresponding candidate character of character and graphic stored and selected literal in advance, and this candidate character is shown in the candidate character display part once more from the candidate character storage part 26 of the storage part 23 of Fig. 1.In addition, in step S55, also can be identical with the step S35 of Fig. 4, the character and graphic that is presented at handwriting input portion through 10 pairs of handwriting input character recognition portion carries out literal identification processing once more, and its recognition result is shown in the candidate character display part.
Afterwards, judge whether at the appointed time the character and graphic that is presented at handwriting input portion to be added pen input (step S56).If be judged as here when adding the pen input, the step S2 getting into Fig. 2 by step S65 does same processing with above-mentioned Fig. 2 afterwards.
In step S56, be judged as when the character and graphic that is presented at handwriting input portion not being added the pen input, then in step S57, judge whether from the candidate character that the candidate character display part shows, selected any literal at the appointed time.If be judged as here and get into step S66 when not selecting any literal at the appointed time; Though be judged as the user has selected definite literal display part in step S51 literal; But the result who in the pairing candidate character of this literal figure, does not exist the user to want, the step S1 that returns Fig. 2 carries out handwriting input again.
In contrast; In step S57, be judged as when from candidate character, having selected any literal; Then judge the definite indication of the input of whether having carried out selected literal at the appointed time; For example when touching definite indication operation such as not shown definite key, get into step S67 selected literal is confirmed as the handwriting input literal, the processing after the step S7 that returns Fig. 2 by step S68 then carries out.
Judge in step S58 when definite operation not imported in selected literal at the appointed time that character and graphic size with regulation on the assigned position of handwriting input portion of the literal that then in step S59, will select from the candidate character display part shows.The character and graphic that show this moment is to be stored in the identification of handwriting input literal with the grapholect figure in the database 11.In step S60, the user adds an input operation on the character and graphic that handwriting input portion shows, return the step S2 of Fig. 2 then through step S61 afterwards, the later handwriting input literal identification processing of doing same as described above.
According to processing shown in Figure 5, can accomplish action for example shown in Figure 10.Promptly; In Figure 10 (a), " gold " though word is in the state of being determined as the 1st word, the user was when the 1st word of handwriting input " gold " word at that time; Discovery is in the candidate character of the literal recognition result of " gold " word; There is a part of identical " branch " word, wants it is utilized, just selected " gold " word that shows on definite literal display part 43 with " powder " word of wanting afterwards to import.According to the selection of Figure 10 (a), in the handwriting input text handwriting of " gold " when in handwriting input portion 41, showing handwriting input before, the identical candidate character of demonstration when on candidate character display part 42, showing handwriting input before.
At this moment; The user selects " branch " word from the candidate character that is presented at candidate character display part 42; And by the step S58 of Fig. 5, when not importing definite operation in (as 3 seconds) at the appointed time, shown in Figure 10 (b); Read and the corresponding grapholect figure of selected " branch " word with database 11 from the identification of handwriting input literal, and replace the character and graphic of previous " gold " word that shows in handwriting input portion 41, to show.In addition; If after " gold " word is confirmed as the 1st word; When the user thinks that " branch " word is imported as the 2nd word; Under the state of Figure 10 (a), above-mentioned long the pressure or double click operation carried out in the display part that is presented at " branch " word on the absent Chinese character display part 42, both can realize directly confirming input to it.
Afterwards, the example shown in Fig. 8 (c) is identical, carries out the mobile processing of " branch " word and the adjusting of size and handles, and Figure 10 (c) illustrates this literal figure and dwindles demonstration on the right side.In addition; If judge that with the result of each grapholect figure of storage in the database 11 this " branch " word is as the possibility by the right avertence when high according to the identification of retrieval handwriting input literal by hand input device itself; Also can be without the state of Figure 10 (b), and directly make the character and graphic of " branch " dwindle demonstration on the right side.Under this state, the user adds pen input " rice " word in the character and graphic left side of " branch " word.Carry out literal identification once more and handle adding character and graphic integral body behind the pen then, its result's candidate character is shown on candidate character display part 42.If the user has selected " powder " word in candidate character, the literal input of being somebody's turn to do " powder " word just is determined, and " powder " word just is shown in like Figure 10 (d) confirms then " gold " word demonstration on the literal display part 43.Like this, the present invention not only can effectively utilize the literal of confirming on the literal display part, can also effectively utilize the candidate character of selecting from the candidate character display part.
