In this case, be easy to occur for example situation as shown in Figure 12 (d), hand-written defeatedEnter the interior space that there is no to supply to input " wood " word of picture area of portion 51. Only be handwriting input into Figure 12 (d)Shown degree, character and graphic and handwriting input literary composition for the identification being generated by inputted handwriting person's handwritingWord identification is too low by the similarity of the grapholect figure of " beam " word of storing in database, therefore candidateOn word display part 52, can not demonstrate user's desirable " beam " word. At this moment, the candidate character of demonstrationIn both do not had user to want word, in handwriting input portion 51, also not having can be for a space of adding, soThe handwriting person's handwriting of can only cancellation so far inputting is back to initial picture, after considering the balance of word entirety asShown in Figure 12 (a), start to re-enter the size than input last time from the top in the region of handwriting input portion 51Little character and graphic.

When complicated Chinese character that particularly number of strokes is a lot of in the very little handwriting input portion 51 of area, warpOften can there is handwriting input and also not complete, in handwriting input portion 51, can supply to add the but situation of deficiency of space of pen,Now user's input of just having to re-start, inconvenience very. Beyond Chinese character input, for example Korea SAlso can there is same problem in the input of other languages such as language.

Therefore, object of the present invention is just to provide a kind of hand-written character input method and handwriting character inputting device,In the time carrying out the handwriting input of word, even also do not inputted at character and graphic the handwriting input portion that just occursThe situation of adding an insufficient space, also there is no need to carry out re-entering of character and graphic, can easily must enterRow adds an input operation.

In order to carry out above-mentioned processing, in the time for example carrying out handwriting input as shown in Figure 11 (a), outer rim detectsPortion 27 detects on the above-below direction of handwriting input text handwriting of menu frame 54 as shown in Figure 11 (b)And each the most outstanding point on left and right directions, the each point detecting is connected with horizontal line and vertical lineQuadrangularly, sets this quadrangle as handwriting input text handwriting outer rim.

Figure 11 (c) has embodied other examples of handwriting input text handwriting outer rim method for detecting. At this exampleIn, taking the center (center of gravity) of handwriting input text handwriting as benchmark, by the most outstanding portion in all directionsPoint extract out as projecting point, connect each projecting point of extracting out and the polygon forming is used as handwriting inputText handwriting outer rim is set. So, can adopt several different methods to set outside handwriting input text handwritingFrame. Outer rim area calculating part 28 calculates the handwriting input word being detected by above-mentioned outer rim detecting element 27The frame inner area of person's handwriting outer rim, outer rim Area Ratio calculating part 29 utilizes the input of storage in storage part 30Picture area data 31, frame inner area and menu frame 4 (Fig. 8 of calculating handwriting input text handwriting outer rimTo the symbol 54 of Figure 11) the ratio of frame inner area. If the Area Ratio obtaining is thus large, with respect to pictureArea in frame 4, the area in handwriting input person's handwriting outer rim accounts for regulation ratio when above, is judged asInput space deficiency.

In storage part 30, except having stored above-mentioned input picture area data 31, also having stored willThe handwriting input text handwriting data 32 that each person's handwriting of handwriting input text handwriting 5 represents by coordinate data,As described later handwriting input text handwriting is moved, dwindled while demonstration, read this handwriting input text handwriting numberAccording to 32, it is carried out the mobile processing in menu frame 4 or dwindles processing. Definite literary composition in storage part 30Digital data 33 is to be shown in and to determine that one on word display part 7 connects according to the sequencing of being determined as mentioned aboveString is determined the data of text line, and these data can be used to described later in order to carry out guider destination settingThe facility name input of carrying out etc.

Handwriting input text handwriting shows that adjustment part 34 possesses display position adjustment part 35, display size adjustment part42, wherein, display position adjustment part 35 is roughly divided into automatic adjustment part 36 and manual adjustment part 39. WhenAbove-mentioned handwriting input text handwriting menu frame contact detecting element 24 detects the handwriting input word in handwriting inputWhen person's handwriting contacts with menu frame 4, the handwriting input text handwriting menu frame in above-mentioned automatic adjustment part 36 connectsIt is to be positioned on which bar limit of rectangular frame frame 4 that tactile position testeding outleting part 37 detects above-mentioned contact position, and makes handWriting input characters person's handwriting moves from the opposition side of trend contact edge. For example, the handwriting input literary composition in handwriting inputWhen word person's handwriting contacts with the limit of the below of menu frame 4, by the handwriting input word inputted thithertoThe entirety of person's handwriting moves and shows to the top in menu frame 4.

And, when the not enough detecting element 23 of the above-mentioned input space detects (handwriting input detecting element in menu frame 4In 2) the input space when not enough, the identification such as the handwriting input text handwriting radicals by which characters are arranged in traditional Chinese dictionaries of adjustment part 36 is adjusted automaticallyPortion 38 carries out following processing: if the handwriting input text handwriting that judgement has been inputted is known as handwriting input wordDo not use the radicals by which characters are arranged in traditional Chinese dictionaries of the Chinese character in database 11 etc., the probability existing on where is high, and according to this judgementResult moves above-mentioned handwriting input text handwriting to specific direction. For example, the probability that becomes " by left avertence " is highTime, handwriting input text handwriting is moved to guarantee that the input space on right side (adds to the left side in menu frame 4Space), same, become the probability of " by right avertence " and handwriting input text handwriting is moved to the right when high,Become the probability of " prefix " and handwriting input text handwriting is moved upward when high, become the several of " at the bottom of word "When rate is high, make handwriting input text handwriting move downwards. Here except judging hand-written defeated in inputEntering text handwriting becomes outside the probability height of which kind of radicals by which characters are arranged in traditional Chinese dictionaries, can also carry out following processing: by this handwriting inputText handwriting is identified as a part for Chinese character, and judges that this part is at handwriting input word identification numberThe probability where above existing according to the various Chinese characters in storehouse 11 is high.

Even can not enter the position of handwriting input text handwriting in input by above-mentioned automatic adjustment part 36In the self-adjusting situation of row, also can be by manual adjustment part 39 according to user's intention, by handwriting inputText handwriting moves arbitrarily with manual form. Moving direction instruction detecting element 40 detects user'sFor example operate the operational motion of the direction display key etc. of 8 directionkeys switches or operation touch-screen. And, dragDrag detecting element 41 and detect user's drag operation, user has inputted with finger touch on touch-screenA part for handwriting input text handwriting, and by it to desirable direction pulls on picture operation. Pass throughThese moving direction instruction detecting elements 40, drag operation detecting element 41 detect and have carried out handwriting input text handwritingMove operation time, the direction that handwriting input person's handwriting is specified by manual adjustment part 39 to user is movedMoving.

When the adjustment of display position of handwriting input text handwriting is carried out in display position adjustment part 35 as previously mentioned,Carry out this handwriting input word the display size adjustment part 42 of handwriting input text handwriting demonstration adjustment part 34Person's handwriting entirety is dwindled the adjustment of the display size of demonstration etc. Now, can also carry out following processing: hand-written defeatedEnter text handwriting and more move to the bight of menu frame 4, its minification corresponding to it is just larger etc. In addition,Make above-mentioned display position adjustment part 35 not carry out the adjustment of the display position of handwriting input text handwriting, this is aobviousShow that adjusted size portion 42 also can dwindle this handwriting input text handwriting in same position, thereby reallyThe input space (adding a space) in menu frame 4 after protecting.

In addition, as shown in the handwriting input text handwriting display case 18 in Fig. 1 lower right menu frame 4,18-1Embody when handwriting input Chinese character " beam ", do not had space to input its below person's handwriting " wood " for userThe situation of word, 18-2 has embodied the handwriting input text handwriting of having inputted with automatic or manual mode limitMobile limit, top to menu frame 4 dwindles, thereby forms the situation of adding a space, and 18-3 has embodied at this and addedA situation of adding pen input " wood " word in space, 18-4 has embodied final Chinese character " beam " by what correctly inputState.

The present invention that functional block forms as shown in Figure 1 can be by the workflow shown in Fig. 2～Fig. 7 with respectivelyPlanting form implements. In the example of the handwriting input word identifying processing shown in Fig. 2, at first hand-writtenHandwriting input text handwriting (step S1) in input part, is undertaken by the not enough detecting element 23 of the input space afterwardsInput space deficiency as shown in Figure 3 detect processing (step S2).

Then judge whether to detect input space deficiency (step S3), while detecting input space deficiency, enterStep S4. In step S4, judged whether to carry out handwriting input text handwriting by automatic adjustment part 36Automated movement processing, may carry out automated movement process time enter step S11, carry out the input shown in Fig. 5The automated movement processing of handwriting person's handwriting when insufficient space. In addition, in the step S4 of present embodiment,Judge as carrying out the automatic processing of handwriting input text handwriting in following situation: in the input of step S2Insufficient space detects and in processing, detects the situation that handwriting input text handwriting contacts in menu frame 4, or,Use the identification that character and graphic generating unit 9 generates to use by identification the handwriting input text handwriting based on having inputtedCharacter and graphic and the standard literary composition that is stored in the each word (Chinese character) of handwriting input word identification in database 11Word figure compares, and handwriting input text handwriting is that the probability of a part of Chinese character radicals or Chinese character is in instituteSituation more than definite value. Except said circumstances, be judged as and can not carry out automated movement processing.

On the other hand, while being judged as by step S4 the automated movement processing that can not carry out handwriting input text handwriting,To, with not detect the input space in step S3 identical when not enough, enter step S5, by manual adjustment part39 judge whether user carries out the move operation of handwriting input text handwriting. Here user is by operation 8The direction display key of directionkeys, touch-screen is indicated the movement of handwriting input text handwriting, moving direction instructionWhen detecting element 40, drag operation detecting element 41 detect aforesaid operations, enter step S12, refer to according to mobileShow that carrying out the mobile of handwriting input text handwriting processes. Moving of the handwriting input text handwriting of this step S12When moving, in order to ensure enough input spaces (adding a space), preferably change handwriting input text handwritingDwindle processing.

When being judged as user in step S5 and not carrying out the move operation of handwriting input text handwriting, and in stepThe manual movement of the handwriting input text handwriting of rapid S12 and dwindling enters step S6, root after processing and carrying outCarry out the identifying processing of word according to the handwriting input text handwriting of having inputted. This word identifying processing carries out followingProcess: by the handwriting input text handwriting of having inputted by identify remove by character and graphic forming portion 9 tiny protrudingRecessed, make it to be transformed into the curve of straight line or regulation, thereby form identification character and graphic, then by this knowledgeYong character and graphic and the grapholect figure of each word of storage in database 11 for the identification of handwriting input wordCompare, extract with database 11 similarity of using character and graphic with above-mentioned identification from the identification of handwriting input word outWord more than setting. Then, judge that above-mentioned handwriting input word identifies with whether depositing in database 11At the word (step S7) more than setting with the similarity of above-mentioned handwriting input text handwriting, if judgementEnter step S13 when not there is not this word, carry out shown in Fig. 6 can not identify input characters time processing.

While there is not this word by step S7 judgement, enter step S8, according to discrimination (with above-mentioned grapholectThe similarity of figure) height order on candidate character display part 6, show this word. Afterwards, in stepIn S9, judge whether user has selected a candidate from the candidate character of candidate character display part 6 demonstrationsWord, if when judgement is not selected, enter step S14, carries out the non-selected candidate's literary composition shown in Fig. 7Processing when word. Otherwise, while being judged as by step S9 the selection of having carried out candidate character, selected word is doneFor handwriting input word is determined (step S10), this is determined to word passes through to determine word Graphics Processing portion20 are shown in definite word display part 7.

In Fig. 2, the input space deficiency of step S2 detects processing as shown in Figure 3, starts to judge hand-written defeated mostEnter text handwriting whether contact with menu frame 4 (step S21). Whether contacting with menu frame 4 nowAlthough judgement carry out based on above-mentioned various detection methods, also can adopt following processing more earlyDetect input space deficiency: when menu frame 4 is neighborings of the viewing area of handwriting input display part 3The boundary line of the neighboring of the input area of edge or handwriting input detecting element 2, by being exported by touch-screenContact position coordinate measurement go out the method that finger or pen contacted the position coinciding with this boundary line and examineWhen going out hand-written input characters person's handwriting and contacting with menu frame 4, above-mentioned boundary line is set in to above-mentioned handwriting inputThe neighboring of the input area of the neighboring of the viewing area of display part 3 or handwriting input detecting element 2Slightly inner side.

While judging that by step S21 handwriting input text handwriting contacts with menu frame 4, enter step S26, inspectionMeasure input space deficiency. Otherwise, judge that by step S21 handwriting input text handwriting does not have and menu frame 4While contacting, enter step S22, judge whether handwriting input has stopped the stipulated time (for example 7 seconds etc.).Concrete, stop the rear stipulated time through detecting element 25 by handwriting input, judge in handwriting input operationAfter way stops, that in the stipulated time, does not carry out handwriting input text handwriting adds pen operation and candidate characterSelect instruction operation or other any operations. Here judge that handwriting input stops not entering in the rear stipulated timeWhen any operation of row, enter step S26, infer due to input space deficiency, cause user slow for a long timeCannot carry out operation below, thereby judge input space deficiency. Then return to Fig. 2's by step S25Whether step S3, detect the judgement of processing of input space deficiency and later processing thereof.

In step S22, judge that while not passing through the stipulated time after handwriting input stops, S23 sentences by illustrated stepsBreak and whether carry out detecting locating of input space deficiency according to the outer rim area ratio of handwriting input text handwritingReason, if enter step S24 while having carried out the setting of above-mentioned processing in advance, carries out root as shown in Figure 4Carry out the processing that detects of input space deficiency according to the outer rim area ratio of handwriting input text handwriting.

Otherwise, be judged as and do not set in advance while carrying out above-mentioned processing by step S23, by step, S25 returnsThe step S3 of Fig. 2, proceeds the judgement of the processing that whether detects input space deficiency and later processing thereof.

The outer rim area ratio according to handwriting input text handwriting that the step S24 of Fig. 3 carries out detectsThe processing of input space deficiency as shown in Figure 4, first detects the outer rim (step of handwriting input text handwritingS31). This action is by handwriting input text handwriting outer rim face in the not enough detecting element 23 of the input space of Fig. 1Long-pending detect than the outer rim detecting element 27 of detecting element 26, concrete, by for above-mentioned Figure 11 (a)Shown handwriting input text handwriting carries out detecting as Figure 11 (b) or the processing as shown in Figure 11 (c)Outer rim.

Then, outer rim area calculating part 28 calculates the area (step in the outer rim being detected by step S31Rapid S32), afterwards, outer rim Area Ratio calculating part 29 calculates with respect to handwriting input picture (in menu frame 4)Entire area, the area proportion (step S33) in handwriting input text handwriting outer rim. Now,Outer rim Area Ratio calculating part 29 is by the outer rim area being calculated by outer rim area calculating part 28 and be stored inThe input picture area data 31 of storage part 30 is read, and calculates the ratio of two areas.

Afterwards, in step S34, judge with respect to handwriting input picture area text handwriting outer rim inner areaWhether proportion is more than setting, if be judged as in the time that setting is above, by step, S35 detects inputInsufficient space. With to be judged as above-mentioned ratio in above-mentioned steps S34 not identical in the time that setting is above, logical afterwardsCross the step S3 that step S36 enters Fig. 2, do same processing with aforementioned.

The automated movement of the handwriting input text handwriting of the step S11 of Fig. 2 is processed as shown in Figure 5, first sentencesCut off the hands and write input characters person's handwriting and whether contact menu frame 4. This judgement directly utilizes the step S21 of above-mentioned Fig. 3Judged result. Therefore when judging that by the step S21 of Fig. 3 handwriting input text handwriting contacts with menu frame 4Time, the step S41 of Fig. 5 also judges that handwriting input text handwriting contacts with menu frame 4 and enters step S46,In menu frame 4, by handwriting input text handwriting to the menu frame 4 contacting with this handwriting input text handwritingThe opposition side on limit when moving, this handwriting input text handwriting is dwindled with the ratio (as 70%) of regulation.

On the other hand, in step S41 (the step S21 of Fig. 3), judge that handwriting input text handwriting does not have and pictureWhen face frame 4 contacts, carry out the identifying processing (step of the radicals by which characters are arranged in traditional Chinese dictionaries etc. of the handwriting input text handwriting shown in Fig. 5Rapid S42). The identifying processing that step S42 carries out is different from common word identifying processing, this identifying processingObject be in order to allow the identification adjustment parts 38 such as the handwriting input text handwriting radicals by which characters are arranged in traditional Chinese dictionaries of Fig. 1 judge the hand of having inputtedWrite input characters person's handwriting whether there is a strong possibility that property makes as the radicals by which characters are arranged in traditional Chinese dictionaries of Chinese character or a part for Chinese characterWith. Above-mentioned common word processing refers to: by input handwriting input text handwriting (by this handwriting input literary compositionThe identification text handwriting that word person's handwriting forms) be stored in handwriting input word identification with in database 11 respectivelyThe grapholect figure of word is compared, is identified.

That is to say, even if the handwriting input text handwriting of having inputted can not be identified as word, also doFollowing identifying processing: by with the mark that is stored in the each word of above-mentioned handwriting input word identification in database 11The part consistent degree of accurate character and graphic is as judgment standard, judges the whether conduct of this handwriting input text handwritingChinese character radicals exists, or, even if do not exist as Chinese character radicals, judge that whether this text handwriting is as the ChineseA part for word is used, for example, text handwriting while not inputting " wood " below above-mentioned " beam " word.

In step S43, be judged as handwriting input text handwriting quilt by the identifying processing result of above-mentioned steps S42When the possibility that uses as radicals by which characters are arranged in traditional Chinese dictionaries etc. is very large, in step S44, according to becoming which type of radicalRadicals by which characters are arranged in traditional Chinese dictionaries (by left avertence, by right avertence, at the bottom of prefix, word), by this handwriting input text handwriting in menu frame 4Either direction moves. For example,, if when handwriting input text handwriting is high as the other probability using of left avertence, madeHandwriting input person's handwriting moves to the left in menu frame 4; If handwriting input text handwriting is as right avertenceWhen the other probability using is high, make handwriting input person's handwriting to the right-hand movement in menu frame 4; If hand-writtenThe probability that input characters person's handwriting uses as prefix is when high, makes handwriting input person's handwriting in menu frame 4Top is mobile; If the probability that handwriting input text handwriting uses at the bottom of as word when high, makes handwriting inputPerson's handwriting moves to the below in menu frame 4.

Same, in step S42, detect the part that handwriting input text handwriting is Chinese character (non-radicals by which characters are arranged in traditional Chinese dictionaries)Time, wipe out the possibility that this handwriting input text handwriting as which part of upper and lower, left and right of Chinese character usesProperty high, and according to detect result by handwriting input text handwriting in the interior movement of menu frame 4. Therefore, upperState " beam " word and be transfused under the state of " wood " word of also not inputting below midway, it is hand-written that this has been inputtedThough input characters person's handwriting can not be used as radicals by which characters are arranged in traditional Chinese dictionaries and identify, be detected as a part for Chinese character and be positioned at the ChineseWord top possibility very high, thereby can make this handwriting input text handwriting automatically be moved upward.

In addition, in step S44, the handwriting input text handwriting that makes to be input to midway moves in menu frame 4Moving time, preferably can consider the input space (adding a space) after guaranteeing, by this handwriting input wordPerson's handwriting in accordance with regulations size dwindles processing.

Judge that by step S43 handwriting input text handwriting can not serve as a part for radicals by which characters are arranged in traditional Chinese dictionaries or the Chinese character of Chinese characterWhile being identified, enter step S47, judge that this handwriting input text handwriting can not carry out automated movement processing, soAfter enter step S45, carry out the later processing of Fig. 2 step S5.

And, carried out the mobile processing of dwindling of handwriting input text handwriting by above-mentioned steps S46, step S44After, also enter step S45, carry out the processing after the step S5 of Fig. 2.

Processing when input characters in the step S13 of Fig. 2 can not be identified as shown in Figure 6. At first, showFollowing instruction: because handwriting input word is identified with not existing in database 11 and handwriting input text handwriting phaseCorresponding word, please inputs (step S51) again. Afterwards, after the indicated number of step S51 finishes, sentenceBreak whether passed through the stipulated time (for example 4 seconds), be judged as while not passing through the stipulated time, enter step S53,Judge whether user has carried out returning the instruction operation of handwriting input.

Otherwise, if when the stipulated time has been passed through in judgement in step S52, enter as shown in the figure step S57, disappearRemove the handwriting input text handwriting of input before, return to the step S1 of Fig. 2 by step S58, carry out newHandwriting input processing. When user has carried out returning the instruction operation of handwriting input in step S53, enter stepS57, cancellation handwriting input character and graphic, the step S1 that returns to Fig. 2 by step S58 carries out new hand-writtenInput processing.

And, in the time being judged that by step S53 instruction that user does not return to handwriting input operates, enterEnter step S54 and judge whether user has carried out changing the instruction operation of character input method, if judgement is notWhile having the operation instruction of the input method of changing, judge by step S59 whether user carries out furtherHandwriting input (add pen) operation.

If judged here when user has carried out further handwriting input, aobvious in the instruction of step S51In stipulated time after showing, user does not return to the instruction of handwriting input, and user does not also indicateChange character input method, when user has carried out further handwriting input under this state, due to meaningTaste and is proceeded handwriting input, therefore returns to the step S2 of Fig. 2, and hand-written input characters person's handwriting is entered repeatedlyRow detects the action after the not enough processing of the input space. In addition, if judge in step S59 that user does not haveWhile carrying out further handwriting input, return to step S52, repeatedly carrying out step through before the stipulated timeThe processing that S53 is later.

Otherwise, if judged in step S54 when user has carried out changing the operation instruction of character input method,Before cancellation, the hand-written book text handwriting (step S55) of input, enters step S56, changes to user instituteThe input method (as spelling input method) of instruction.

Processing when the non-selected candidate character of the step S14 of Fig. 2 as shown in Figure 7, judges hand-written literary composition at firstAfter stopping, word input whether passes through the stipulated time for example 4 seconds (step S61). Here be judged as through ruleWhile fixing time, by step S66, the handwriting input text handwriting of input is before eliminated, in step, S67 returnsThe step S1 that returns Fig. 2, carries out new handwriting input processing.

On the contrary, when in step S61, judgement is not also passed through the stipulated time, whether step S62 judges userCarry out returning the instruction operation of handwriting input, be judged as while having carried out this instruction operation, equally as previously mentioned,Cancellation handwriting input text handwriting in step S66, is returned to the step S31 of Fig. 2 by step S67. Otherwise,When being judged as user in step S62 and not returning to the instruction operation of handwriting input, by step, S63 sentencesWhether disconnected user has carried out changing the instruction operation of character input method, is judged as here to have carried out changing to refer toWhile showing operation, eliminate handwriting input text handwriting by step S64, enter step S65 and change to other inputsMethod. While judging that by step S63 the instruction of not changing operates, return to step S61, to process regulationBefore time, repeatedly carry out the later processing of step S62.

The handwriting character inputting device of embodiment of the present invention, according to the motion flow of aforesaid Fig. 2～Fig. 7, entersThe action processing as shown in Figure 8 of row example. In Fig. 8 to Figure 11, symbol 51 represents the (Fig. 1 of handwriting input portionHandwriting input detecting element 2 and handwriting input display part 3), symbol 52 represents candidate character display part, symbol53 represent to determine word display part, and symbol 54 represents the menu frame of handwriting input portion 51. In these figure,Menu frame 54 is not the physical frame outstanding with frame shape, but represents the reality of handwriting input display part 3The outer peripheral boundary line of the input area of region and handwriting input detecting element 2. Therefore, by handwriting inputThe contact position coordinate that the touch-screen of detecting element 2 is exported, the handwriting input text handwriting picture shown in Fig. 1Frame contact detecting element 24 detects finger or pen has contacted the position coinciding with above-mentioned boundary line, thus inspectionMeasuring handwriting input text handwriting contacts with the limit of menu frame 54. But, form the above-mentioned of menu frame 54Outward flange or handwriting input that boundary line also can be set in the viewing area of handwriting input display part 3 detectThe outer peripheral of the input area of portion 2 located slightly in the inner part.

Fig. 8 is situation about having embodied while finally wanting " win " word shown in handwriting input Fig. 8 (d). At Fig. 8(a) in, embodied in handwriting input portion 51 and inputted after the part that is positioned at this word top, there is no handState while writing the input space of inputting the input characters lower part of wanting.

In the stage shown in Fig. 8 (a), as the result of carrying out word identification according to handwriting input text handwritingBe displayed on " win " word that does not occur desired input in the candidate character on candidate character display part 52,Therefore be necessary to carry out further handwriting input. As shown in Fig. 8 (b), user passes through drag operationCarry out the instruction operation that this handwriting input text handwriting is moved upward. ,, as shown in Fig. 8 (b), useFinger in handwriting input portion 51 by below upward slide, make shown handwriting input text handwriting upwardsFang Yidong. Now, the drag operation detecting element 41 of the manual adjustment part 39 shown in Fig. 1 detects above-mentioned cunningMoving operation, interior by handwriting input text handwriting upward at menu frame 54 by display position body adjustment part 35Move and show. Meanwhile, display size adjusting portion 42 by handwriting input text handwriting by for example 60% regulationRatio is dwindled demonstration. Like this, user carry out handwriting input text handwriting display position regulateWhen operation, display size adjusting portion 42 ratio according to the rules, or for this handwriting input text handwriting is becomeBecome prescribed level, automatically expand/dwindle this character and graphic, thus be convenient to user more easily add pen defeatedEnter operation. In addition, the expansion/minification of handwriting input text handwriting or this handwriting input text handwriting is aobviousShow size also can carry out suitable setting by display size adjusting portion 42 by user.

As a result, as shown in Fig. 8 (c), this handwriting input text handwriting moves to the top of handwriting input portion 51And reduced demonstration. Therefore, due to the space of adding forming below above-mentioned handwriting input text handwriting,Afterwards user add pen inputted the person's handwriting in the dotted line frame as shown in Fig. 8 (d), add the handwriting input after penThe recognition result of text handwriting is shown on candidate character display part 52, and user operates etc. it by touchIn candidate character " win " word select, thereby as handwriting input word determine, afterwards determine literary compositionOn word display part 53, show this word.

Fig. 9 has embodied while finally wanting " beam " word as shown in Fig. 9 (c), Fig. 9 (d) of handwriting inputSituation. In Fig. 9 (a), embody and in handwriting input portion 51, inputted the part that is positioned at this word topAfter, the state while not having handwriting input to want the input space of input characters lower part " wood ". At Fig. 9(a) in the stage shown in, be displayed on time as the result of carrying out word identification according to handwriting input text handwriting" beam " word that does not occur desired input in candidate character on selection word display part 52, is therefore necessaryCarry out further handwriting input. But user is at a loss and causes hand because the input space is not enoughWrite input and stop, afterwards, within 7 seconds, wait do not carry out in the stipulated time handwriting input text handwriting add pen operation withAnd when the selection of candidate character operation or other operations, after being stopped by the handwriting input of Fig. 1 through regulationTime detecting element 25 detects after this situation, carries out defeated as shown in the step S2 of Fig. 2 (the step S22 of Fig. 3)Enter the judgement of insufficient space. So, the then motion flow of the step S42～step S44 based on Fig. 5,Judge that by identification adjustment parts 38 such as handwriting input text handwriting radicals by which characters are arranged in traditional Chinese dictionaries this handwriting input text handwriting of having inputted isThe high character and graphic of probability being used as a part (top) for Chinese character, result as shown in Fig. 9 (b),Handwriting input text handwriting is moved upward to demonstration by display position adjustment part 35 menu frame 54 is interiorMeanwhile, by display size adjusting portion 42 ratio in accordance with regulations, above-mentioned handwriting input text handwriting is dwindled to demonstration.

Afterwards, on the space of being vacated by moving of above-mentioned handwriting input text handwriting, as Fig. 9 (c)The interior user of shown dotted line frame adds pen and has inputted text handwriting " wood ", adds the handwriting input text handwriting after penRecognition result be shown on candidate character display part 52, user operates etc. candidate wherein by selectionWord " beam " word is selected, thereby determines as handwriting input word, afterwards as Fig. 9 (d) is shown inDetermine and on word display part 53, show this word.

Figure 10 only shows, by display size adjustment part 42, hand-written input characters person's handwriting is dwindled to processingAnd the situation of an input space is added in formation. Identical with Fig. 9 (a), after having inputted handwriting input text handwriting,Detect to process by the input space deficiency shown in the step S2 (the step S22 of Fig. 3) of Fig. 2 and inputWhen the detecting of insufficient space, as shown in Figure 10 (b) not the display position of mobile handwriting input characters person's handwriting (inHeart position), only adjust the display size of handwriting input text handwriting by display size adjustment part 42, as figureShown in 10 (c), handwriting input text handwriting is dwindled to demonstration. Result is the surrounding shape of handwriting input text handwritingA space of adding that becomes to comprise handwriting input text handwriting below is used in the dotted line frame as shown in Figure 10 (c)Person can add an input characters person's handwriting " wood " below handwriting input text handwriting.

Accordingly, as shown in Figure 10 (d), the recognition result that adds the handwriting input text handwriting after pen is shown in timeOn selection word display part 52, user operates etc. using candidate character wherein " beam " word as hand by selectionWriting input characters determines. No matter where handwriting input text handwriting can both carry out this menu frame 54The handwriting input text handwriting of sample dwindle processing.

Situation shown in Figure 11 is identical with Fig. 8, is finally to want " win " shown in handwriting input Figure 11 (f)Situation when word. In Figure 11 (a), embody in handwriting input portion 51 and inputted and be positioned on this wordAfter the part of portion, the state while not having to want the input space of input characters lower part for handwriting input.In the stage shown in this Figure 11 (a), carry out the step S2 of Fig. 2, i.e. input space deficiency shown in Fig. 3Detect processing, but in the present embodiment, in the step S23 of imaginary picture of primitive people 3, be by handwriting input word penThe outward flange frame area ratio of mark carries out input space deficiency and detects processing. Thereby, in Figure 11 (a) instituteUnder the state showing, carry out the outward flange frame ratio according to handwriting input text handwriting shown in Fig. 4 and detect defeatedEnter the processing that detects of insufficient space. The content of this processing is: as the handwriting input word at the above-mentioned Fig. 1 of explanationDescribed in when person's handwriting outer rim Area Ratio detecting element 26, first pass through outer rim detecting element 27 as Figure 11 (b)Or as shown in Figure 11 (c), set and surround the quadrangle of handwriting input text handwriting or polygonal hand-writtenInput characters person's handwriting outer rim. Then, outer rim area calculating part 28 calculates handwriting input text handwriting outsideThe frame inner area of frame, outer rim Area Ratio calculating part 29 utilizes the input picture area of storage in storage part 30Data 31, calculate the frame inner area of handwriting input text handwriting outer rim and the ratio of the frame inner area of menu frame 4.Then,, with respect to the area in menu frame 4, the area in handwriting input person's handwriting outer rim accounts for regulation ratioWhen example is above, be judged as input space deficiency.

Afterwards, identical with Fig. 9 illustrated embodiment, the stream of action of the step S42～step S44 based on Fig. 5Journey, judges by identification adjustment parts 38 such as handwriting input text handwriting radicals by which characters are arranged in traditional Chinese dictionaries the handwriting input word pen that this has been inputtedThe probability that mark is used as a part (top) for Chinese character is high, as Figure 11 (d) and Figure 11 (e) instituteShow, handwriting input text handwriting is moved upward aobvious by display position adjustment part 35 menu frame 54 is interiorWhen showing, by display size adjusting portion 42 ratio in accordance with regulations, above-mentioned handwriting input text handwriting is dwindledShow. As a result, below above-mentioned handwriting input text handwriting, form and add a space, adding a space as figureShown in 11 (f), add pen while having inputted text handwriting or adding pen input midway, the word of desired inputWhen " win " is shown on candidate character display part 52, user operates etc. this word " win " by selectionDetermine as handwriting input word, and be presented on definite word display part 53.

In addition, though also there is following situation in Fig. 8 to Figure 11 not shown: as shown in Figure 8 hand-written defeatedEnter the input of text handwriting midway, the part bottom of " mouth " of below and menu frame 54 (above-mentioned limitBoundary line) coincide below. , can there is finger when handwriting input or pen moves to menu frame 54 eachThe situation of the position that limit coincides. In this case, in preceding method, handwriting input text handwriting is drawnFace frame contact detecting element 24 detects handwriting input handwriting input text handwriting and menu frame 54 midway and joinsTouch, thereby the judged result of the step S41 of the step S21 of Fig. 3 and Fig. 5 is " YES ", the hand of Fig. 1Writing input characters person's handwriting menu frame contact position, to detect adjustment part 37 interior by handwriting input word at menu frame 54Person's handwriting is to the opposition side automated movement of institute's contact edge time, and display size adjustment part 42 is by handwriting input wordPerson's handwriting dwindles demonstration. As a result, as shown in Fig. 8 (c), above menu frame 54 (contrary with contact edge oneSide) the reduced demonstration of handwriting input text handwriting inputted, its below forms a broad space of adding. ItAfter action identical with the embodiment shown in Fig. 8, just repeat no more herein.
