The handwriting character inputting device of this embodiment has candidate character display part 6, and this above-mentioned candidate character display part 6 is adjacent with handwriting input display part 3, shows the candidate character as the literal identification result of handwriting input text handwriting.The handwriting character inputting device of this embodiment also has definite literal display part 7; When the user selects from the candidate character that is shown in above-mentioned candidate character display part 6, this selected literal is just as confirming that literal is shown in above-mentioned definite literal display part 7.According to confirming at this on literal display part 7 according to the text line of confirming that sequencing shows, for example entry device name etc. on guider just can be set the place that this facility belongs to as the destination.In addition; In this embodiment; Include handwriting input portion 1, candidate character display part 6, confirm that the picture of literal display part 7 is made up of 1 display unit such as LCDs; On the surface of this picture integral body, dispose touch-screen overlappingly, on the viewing area of each display part, can carry out touch operation, slide.

Selection indication detecting element 8 shown in Figure 1 detects the user selects any literal from a plurality of candidate characters that are shown in above-mentioned candidate character display part 6 selection indication operation.Selected literal is confirmed literal display part 7 as confirming that literal is shown in.By having a lot of tiny convex-concaves on the straight line of each person's handwriting in the handwriting input text handwriting 5 of above-mentioned handwriting input portion 1 input, the curve; And the input angle of each person's handwriting be vertical originally or the situation of level under also regular meeting input appears tilting, will cause the literal discrimination of handwriting input person's handwriting low like this.Therefore, through the tiny convex-concave portion in the handwriting input text handwriting 5 is removed, with the straight line of each person's handwriting, curve carries out conversion etc. to be made it to become and carries out the identification that literal identification handles easily and use character and graphic with character and graphic generation portion 9 in identification.

Handwriting input character recognition portion 10 will be discerned the identification that generates with character and graphic generation portion 9 and compare with the grapholect figure in the database 11 with being stored in the identification of handwriting input literal in advance with character and graphic, carry out the identification of handwriting input literal and handle.Handle according to the identification of handwriting input character recognition portion 10, recognition result judging part 12 detects when not having suitable candidate character, just shows the information that means " the handwriting input literal can not be discerned " on the display part 13 can not discerning.

By selecting indication portion 14 to realize the selection operation that users carry out for as shown in Figure 1 various function portion.Wherein, through candidate character selection portion 15, the user can select for the desirable literal in a plurality of candidate characters on the show candidate literal display part 6.This selection operation can be through detecting the realizations such as touch operation of user to any candidate character of above-mentioned candidate character display part 6 demonstrations by above-mentioned selection indication detecting element 8.

The handwriting input text handwriting moves indication portion 16 and indicates as follows: the display position that makes handwriting input not accomplish the handwriting input text handwriting in stage moves in handwriting input display part 3.This handwriting input text handwriting move mobile indication that indication portion 16 carries out through after state manual adjustment portion 39 moving direction indication detecting element 40 detect; Display position adjustment part 35 detects the result according to this, moves the display position of the handwriting input text handwriting in the handwriting input.Handwriting input confirms that indication portion 17 will confirm indication as definite literal by the candidate character that above-mentioned candidate character selects indication portion 15 to select to indicate.This handwriting input confirms that indication portion 17 carries out definiteness really and shows and be that operation that the user carries out not shown definite button realizes through detecting.In addition, because candidate character selects indication portion 15 can selected literal directly be confirmed as definite literal,, handwriting input confirms indication portion 17 so also can not being set.

Candidate character display process portion 19 handles as follows: will on above-mentioned candidate character display part 6, be shown by the candidate character that 10 pairs of hand-written input characters person's handwritings 5 of handwriting input character recognition portion carry out obtaining after the literal identification.And; Confirm that literal display process portion 20 handles as follows: when the user chooses one of which wantonly from candidate character as previously mentioned; Perhaps arbitrary literal is selected when indicating the back to confirm that by handwriting input indication portion 17 confirms indication, and this literal is used as confirms that literal is presented on definite literal display part 7.Being shown in a series of definite text line of confirming literal display part 7 states in the storage part 30 after lteral data 33 is stored in as confirming.

Handwriting input cancellation portion 22 handles as follows: for example dispose when the handwriting input of a literal, and the input of literal is when being determined, cancellation is presented at the handwriting input person's handwriting of the previous input of handwriting input display part 3.In addition; When the handwriting input text handwriting can not be carried out literal identification; Also can not show under the situation of wanting to import such as candidate character even perhaps be identified, finish identification in order to impel the user to import once more and handle, the handwriting input text handwriting cancellation that shows.At this moment, there is literal to show on the candidate character display part, also this display text of cancellation simultaneously.

The not enough detecting element 23 of the input space detects following state: the handwriting input that is arranged in the menu frame 4 of handwriting input display part 3 is not accomplished the handwriting input text handwriting in stage and is in the state under writing not at menu frame 4 (handwriting input detecting element 2), perhaps will be in the state under writing not.Detect according to above-mentioned, after the handwriting input text handwriting stated show the demonstration of the handwriting input text handwriting in the 34 adjustment handwriting inputs of adjustment part.The not enough detecting element 23 of the input space can detect the input space (adding a space) deficiency through the whole bag of tricks.Wherein, can contact with menu frame 4 through the handwriting input text handwriting that above-mentioned method for detecting detects in the handwriting input by handwriting input text handwriting menu frame contact detecting element 24, thereby be judged as input space deficiency.

And; When user's handwriting input proceeds to midway and is under the state that does not have the show candidate literal; After perhaps candidate character shows; When detecting through stipulated time detecting element 25 that (for example 7 seconds) are not carried out the selection operation that adds pen operation and candidate character of handwriting input text handwriting and do not carried out other any operations yet in the stipulated time after stopping through handwriting input, it is not enough to be estimated as the above-mentioned input space.This processing also can combine with the processing that above-mentioned handwriting input text handwriting menu frame contacts detecting element 24 and carry out; For example ought detect handwriting input text handwriting 5 contacts with menu frame 4; And when the user does not carry out any operation in the stipulated time afterwards, be judged as input space deficiency.

And; Set the outer rim of surrounding the handwriting input text handwriting in the handwriting input; Detect the ratio of area that area that above-mentioned outer rim surrounds accounts for menu frame 4 through handwriting input text handwriting outer rim area when setting is above than detecting element 26, it is very big just to be judged as the not enough or not enough possibility of the above-mentioned input space.In order to carry out above-mentioned processing; When for example shown in Figure 11 (a), carrying out handwriting input; On the above-below direction of outer rim detecting element 27 such handwriting input text handwriting that detects menu frame 54 shown in Figure 11 (b) and each the most outstanding point on the left and right directions; Detected each point is connected into quadrilateral with horizontal line and perpendicular line, this quadrilateral is set as handwriting input text handwriting outer rim.

Figure 11 (c) has embodied other instances of handwriting input text handwriting outer rim method for detecting.In this example; Center (center of gravity) with the handwriting input text handwriting is a benchmark; The most outstanding part on all directions is extracted out as projecting point, and each projecting point of connect extracting out and the polygon that forms are used as handwriting input text handwriting outer rim and set.So, can adopt several different methods to set handwriting input text handwriting outer rim.Outer rim area calculating part 28 calculates the frame inner area of the handwriting input text handwriting outer rim that is detected by above-mentioned outer rim detecting element 27; The outer rim area utilizes the input picture area data 31 of storing in the storage part 30 than calculating part 29, the ratio of the frame inner area of calculating handwriting input text handwriting outer rim and the frame inner area of menu frame 4 (symbol 54 of Fig. 8 to Figure 11).If the area that obtains thus is than big, promptly with respect to the area in the menu frame 4, the area in the handwriting input person's handwriting outer rim accounts for the regulation ratio when above, is judged as input space deficiency.

In storage part 30; Except having stored above-mentioned input picture area data 31; The handwriting input text handwriting data 32 that each person's handwriting of handwriting input text handwriting 5 is represented with coordinate data have also been stored; When the handwriting input text handwriting being moved, dwindling demonstration, read this handwriting input text handwriting data 32, it is carried out the mobile processing in menu frame 4 or dwindles processing as the back is said.Definite lteral data 33 in the storage part 30 is to be shown in the data of confirming a succession of definite text line on the literal display part 7, the facility name input of carrying out in order to carry out the guider destination setting that these data are stated after can being used to etc. according to the sequencing that is determined as stated.

The handwriting input text handwriting shows that adjustment part 34 possesses display position adjustment part 35, display size adjustment part 42, and wherein, display position adjustment part 35 roughly is divided into automatic adjustment part 36 and manual adjustment portion 39.When above-mentioned handwriting input text handwriting menu frame contact detecting element 24 detects handwriting input text handwriting in the handwriting input when contacting with menu frame 4; It is to be positioned on which bar limit of rectangular frame frame 4 that handwriting input text handwriting menu frame contact position detecting element 37 in the above-mentioned automatic adjustment part 36 detects above-mentioned contact position, and the handwriting input text handwriting is moved from the opposition side of trend contact edge.For example, when the handwriting input text handwriting in the handwriting input contacts with the limit of the below of menu frame 4, the top of integral body in menu frame 4 of the handwriting input text handwriting of being imported thitherto moved and shown.

And; When the not enough detecting element 23 of the above-mentioned input space detects the input space deficiency of (in the handwriting input detecting element 2) in the menu frame 4; Automatically following processing is carried out in the identification adjustment parts such as handwriting input text handwriting radicals by which characters are arranged in traditional Chinese dictionaries 38 of adjustment part 36: discern with the radicals by which characters are arranged in traditional Chinese dictionaries of the Chinese character in the database 11 as the handwriting input literal etc. if judge the handwriting input text handwriting imported; The probability that exists on where is high, and moves above-mentioned handwriting input text handwriting according to this judged result to specific direction.For example; Become the probability of " by the left avertence " when high; The left side of handwriting input text handwriting in menu frame 4 moved so that guarantee the input space (adding a space) on right side, same, become the probability of " by the right avertence " and the handwriting input text handwriting is moved to the right when high; Become the probability of " prefix " and the handwriting input text handwriting is moved when high to the top, become the probability of " at the bottom of the word " and the handwriting input text handwriting is moved when high downwards.Here except judging that the handwriting input text handwriting in the input becomes the probability height of which kind of radicals by which characters are arranged in traditional Chinese dictionaries; Can also carry out following processing: this handwriting input text handwriting is discerned as part of Chinese character, and judge this part handwriting input literal identification with the various Chinese characters in the database 11 where on the probability height that exists.

Even can not carry out under the self-adjusting situation the position of the handwriting input text handwriting in the input through above-mentioned automatic adjustment part 36; Also can the handwriting input text handwriting be carried out moving arbitrarily with manual form through the intention of manual adjustment portion 39 according to the user.The operational motion of moving direction indication detecting element 40 detection users' the direction display key of for example operating 8 directionkeys switches or operating touch-screen etc.And, pull the drag operation that detecting element 41 detects users, i.e. the part of the handwriting input text handwriting on touch-screen, imported of user with finger touch, and with its operation that desirable direction pulls on picture.Through these moving direction indication detecting elements 40, when drag operation detecting element 41 detects the move operation that has carried out the handwriting input text handwriting, handwriting input person's handwriting is moved to the direction of user's appointment through manual adjustment portion 39.

When the adjustment of display position of handwriting input text handwriting was carried out in display position adjustment part 35 as previously mentioned, the handwriting input text handwriting showed that the display size adjustment part 42 of adjustment part 34 carries out this handwriting input text handwriting integral body is dwindled the adjustment of the display size of demonstration etc.At this moment, can also carry out following processing: the handwriting input text handwriting moves to the bight of menu frame 4 more, and corresponding its minification with it is just big more etc.In addition; Even the adjustment of the display position of handwriting input text handwriting is not carried out in above-mentioned display position adjustment part 35; This display size adjustment part 42 also can dwindle this handwriting input text handwriting on same position, thus the input space (adding a space) in the menu frame 4 after guaranteeing.

In addition; Show shown in the example 18 like the handwriting input text handwriting in Fig. 1 lower right menu frame 4; 18-1 has embodied when handwriting input Chinese character " beam "; Do not have the space to import the situation of its below person's handwriting " wood " word for the user, 18-2 embodied the handwriting input text handwriting that will import with automatically or manual mode limit move the limit to the top of menu frame 4 and dwindle, thereby form the situation of adding a space; 18-3 has embodied at this and has added the situation of adding pen input " wood " word in the space, and 18-4 has embodied final Chinese character " beam " by the state of correct input.

The formed the present invention of functional block as shown in Figure 1 can implement with various forms through Fig. 2～workflow shown in Figure 7.In the instance that handwriting input literal shown in Figure 2 identification is handled, handwriting input text handwriting (step S1) in handwriting input portion at first, afterwards through the not enough detecting element 23 of the input space carry out the input space as shown in Figure 3 not enough detect processing (step S2).

Judge whether to detect input space deficiency (step S3) then, when detecting input space deficiency, get into step S4.In step S4; Judging whether to carry out moving automatically of handwriting input text handwriting by automatic adjustment part 36 handles; Possibly carry out moving automatically entering step S11 when handling, moving automatically of the handwriting person's handwriting when carrying out input space deficiency shown in Figure 5 handled.In addition; Among the step S4 of this embodiment; Judge to carrying out the automatic processing of handwriting input text handwriting in following situation: detect in the input space deficiency of step S2 and detect the situation of handwriting input text handwriting in the processing in menu frame 4 contacts; Perhaps; The identification that will generate with character and graphic generation portion 9 through identification based on the handwriting input text handwriting of having imported with character and graphic be stored in the grapholect figure that the handwriting input literal discerns with each literal (Chinese character) in the database 11 and compare, the handwriting input text handwriting be the probability of Chinese character radicals or part of Chinese character in institute the situation more than the definite value.Except that said circumstances, be judged as and carry out moving automatically handling.

On the other hand; When being judged as mobile automatically processing that to carry out the handwriting input text handwriting by step S4; Will with step S3 in not detect the input space identical when not enough, get into step S5, judge by manual adjustment portion 39 whether the user carries out the move operation of handwriting input text handwriting.Here the user indicates moving of handwriting input text handwriting through the direction display key of operating 8 directionkeys, touch-screen; Moving direction indication detecting element 40, when drag operation detecting element 41 detects aforesaid operations; Get into step S12, carry out the mobile processing of handwriting input text handwriting according to moving indication.When the handwriting input text handwriting of this step S12 mobile,, preferably change the processing of dwindling of handwriting input text handwriting in order to ensure enough input spaces (adding a space).

Be judged as the user among the step S5 when not carrying out the move operation of handwriting input text handwriting; And the handwriting input text handwriting of step S12 manually move and dwindle handle carry out after; Get into step S6, carry out the identification of literal according to the handwriting input text handwriting of having imported and handle.This article word recognition is handled and carried out following processing: the handwriting input text handwriting that will import forms portion 9 by identification with character and graphic and removes tiny convex-concave; Make it to be transformed into the curve of straight line or regulation; Thereby form identification and use character and graphic; To discern then with character and graphic and compare with the grapholect figure of each literal of storage in the database 11, extract out and similarity the literal setting more than of above-mentioned identification with database 11 with character and graphic from the identification of handwriting input literal with the identification of handwriting input literal.Then; Judge that the identification of above-mentioned handwriting input literal is with the literal (step S7) of similarity more than setting that whether exists in the database 11 with above-mentioned handwriting input text handwriting; Get into step S13 if be judged as when not having this literal, carry out processing can not discern input characters time the shown in Figure 6.

Get into step S8 when not having this literal, on candidate character display part 6, show this literal according to discrimination (with the similarity of above-mentioned grapholect figure) order just by step S7 judgement.Afterwards, judge that in step S9 whether the user has selected a candidate character from the candidate character that candidate character display part 6 shows, if judge and get into step S14 when not selecting, the processing when carrying out shown in Figure 7 non-selected candidate character.Otherwise, when being judged as the selection of having carried out candidate character, selected literal is confirmed (step S10) as the handwriting input literal by step S9, should confirm that literal was shown in definite literal display part 7 through confirming literal display process portion 20.

The input space deficiency of step S2 detects and handles as shown in Figure 3ly among Fig. 2, begins to judge handwriting input text handwriting whether contact with menu frame 4 (step S21) most.This moment whether though contacted judgement is based on above-mentioned various detection method carries out with menu frame 4; But also can adopt following processing more early detect input space deficiency: the boundary line of neighboring of input area of neighboring or handwriting input detecting element 2 that when menu frame 4 is the viewing area of handwriting input display part 3; Detect method that finger or pen contacted the position that coincides with this boundary line when detecting the handwriting input text handwriting and contacting through contact position coordinate, above-mentioned boundary line is set in the inboard slightly of neighboring of input area of neighboring or handwriting input detecting element 2 of the viewing area of above-mentioned handwriting input display part 3 with menu frame 4 by touch-screen output.

When judging that by step S21 the handwriting input text handwriting contacts with menu frame 4, get into step S26, detect input space deficiency.Otherwise, when judging that by step S21 the handwriting input text handwriting does not contact with menu frame 4, get into step S22, judge whether handwriting input has stopped the stipulated time (for example 7 seconds etc.).Concrete; Stop the back stipulated time through detecting element 25 through handwriting input; Judgement is not carried out selection indication operation or other any operations of adding pen operation and candidate character of handwriting input text handwriting in the stipulated time after handwriting input operation Halfway Stopping.Here judge that handwriting input stops the back when not carrying out any operation in the stipulated time, get into step S26, infer, cause the user slowly can't carry out following operation for a long time, thereby judge that the input space is not enough because the input space is not enough.Return the step S3 of Fig. 2 then through step S25, whether detect the judgement of the not enough processing of the input space and later processing thereof.

Judge among the step S22 when not passing through the stipulated time after handwriting input stops; Judge whether that by illustrated steps S23 the outer rim area ratio that carries out according to the handwriting input text handwriting detects the not enough processing of the input space; If get into step S24 when having carried out the setting of above-mentioned processing in advance, carry out the processing that detects that the outer rim area ratio according to the handwriting input text handwriting as shown in Figure 4 carries out input space deficiency.

Otherwise, being judged as by step S23 and setting in advance not when not carrying out above-mentioned processing, the step S3 by step S25 returns Fig. 2 proceeds whether to detect the judgement of the not enough processing of the input space and later processing thereof.

It is as shown in Figure 4 that the outer rim area ratio according to the handwriting input text handwriting that step S24 carried out of Fig. 3 detects the not enough processing of the input space, at first detects the outer rim (step S31) of handwriting input text handwriting.This action is to be detected by the outer rim detecting element 27 of handwriting input text handwriting outer rim area in the not enough detecting element 23 of the input space of Fig. 1 than detecting element 26; Concrete, through carry out detecting outer rim for the handwriting input text handwriting shown in above-mentioned Figure 11 (a) like Figure 11 (b) or the processing shown in Figure 11 (c).

Then; Outer rim area calculating part 28 calculates by the area (step S32) in the detected outer rim of step S31; Afterwards; The outer rim area calculates the entire area with respect to handwriting input picture (in the menu frame 4), the area proportion (step S33) in the handwriting input text handwriting outer rim than calculating part 29.At this moment, outer rim area that the outer rim area will be calculated by outer rim area calculating part 28 than calculating part 29 and the input picture area data 31 that is stored in storage part 30 are read, and calculate the ratio of two areas.

Afterwards, in step S34, judge with respect to handwriting input picture area text handwriting outer rim inner area proportion whether more than setting,, detect input space deficiency by step S35 if be judged as when setting is above.Afterwards with to be judged as above-mentioned ratio not identical when setting is above among the above-mentioned steps S34, get into the step S3 of Fig. 2 through step S36, do same processing with aforementioned.

Automatically the mobile processing of the handwriting input text handwriting of the step S11 of Fig. 2 is as shown in Figure 5, judges at first whether the handwriting input text handwriting contacts menu frame 4.This judgement directly utilizes the judged result of the step S21 of above-mentioned Fig. 3.Therefore when the step S21 by Fig. 3 judges that the handwriting input text handwriting contacts with menu frame 4; The step S41 of Fig. 5 judges that also the handwriting input text handwriting contacts with menu frame 4 and gets into step S46; In menu frame 4; The handwriting input text handwriting when the opposition side on the limit of the menu frame 4 that contacts with this handwriting input text handwriting moves, is dwindled this handwriting input text handwriting with the ratio (as 70%) of regulation.

On the other hand, judge among the step S41 (the step S21 of Fig. 3) when the handwriting input text handwriting does not contact with menu frame 4, carry out the identification of the radicals by which characters are arranged in traditional Chinese dictionaries etc. of handwriting input text handwriting shown in Figure 5 and handle (step S42).Identification that step S42 carried out is handled and is handled differently with the identification of common literal, and the purpose of this identification processing is that property is used as the radicals by which characters are arranged in traditional Chinese dictionaries or the part of Chinese character of Chinese character in order to let handwriting input text handwriting that identification adjustment parts such as handwriting input text handwriting radicals by which characters are arranged in traditional Chinese dictionaries 38 judgements of Fig. 1 have imported whether there is a strong possibility.Above-mentioned common word processing is meant: with the handwriting input text handwriting (text handwriting is used in the identification by this handwriting input text handwriting forms) of input be stored in the handwriting input literal and discern and to compare, to discern with the grapholect figure of each literal in the database 11.

That is to say; Even the handwriting input text handwriting of having imported can not be identified as literal; Also doing following identification handles: will be stored in above-mentioned handwriting input literal identification with the part consistent degree of the grapholect figure of each literal in the database 11 as judgment standard; Judge whether this handwriting input text handwriting exists as Chinese character radicals, perhaps, even do not exist as Chinese character radicals; Judge whether this literal person's handwriting is used as part of Chinese character, the text handwriting when for example not importing " wood " below above-mentioned " beam " word.

In step S43, be judged as the handwriting input text handwriting and be used as possibility that radicals by which characters are arranged in traditional Chinese dictionaries etc. use when very big by the identification result of above-mentioned steps S42; In step S44; Which type of, the arbitrary direction of this handwriting input text handwriting in menu frame 4 moved according to becoming radical (by the left avertence, by the right avertence, at the bottom of the prefix, word).For example, if the handwriting input text handwriting when high, moves the left of handwriting input person's handwriting in menu frame 4 as the other probability that uses of left avertence; If the handwriting input text handwriting, makes handwriting input person's handwriting right-hand mobile to menu frame 4 in as the other probability that uses of right avertence when high; If when the probability that the handwriting input text handwriting uses as prefix is high, the top of handwriting input person's handwriting in menu frame 4 moved; If when the probability that the handwriting input text handwriting uses at the bottom of as word is high, the below of handwriting input person's handwriting in menu frame 4 moved.

Same; When in step S42, detecting the handwriting input text handwriting and being part of Chinese character (non-radicals by which characters are arranged in traditional Chinese dictionaries); It is high to wipe out this handwriting input text handwriting possibility that which partly uses as the upper and lower, left and right of Chinese character, and according to the result who detects that the handwriting input text handwriting is mobile menu frame 4 in.Therefore; Be transfused at above-mentioned " beam " word under the state of " wood " word of also not importing the below midway; Though this handwriting input text handwriting of having imported can not be used as radicals by which characters are arranged in traditional Chinese dictionaries and discern; But be detected as part of Chinese character be positioned at Chinese character top possibility very high, thereby this handwriting input text handwriting is moved to the top automatically.

In addition, in step S44, the handwriting input text handwriting that is input to is midway moved in menu frame 4 in, the input space (adding a space) after preferably can considering to guarantee is dwindled processing with this handwriting input text handwriting by given size.

When judging that by step S43 the handwriting input text handwriting can not be identified as the radicals by which characters are arranged in traditional Chinese dictionaries of Chinese character or part of Chinese character; Get into step S47; Judge that this handwriting input text handwriting can not carry out moving automatically handling, get into step S45 then, carry out the later processing of Fig. 2 step S5.

And, undertaken also getting into step S45 after dwindling of handwriting input text handwriting move to handle by above-mentioned steps S46, step S44, carry out the processing after the step S5 of Fig. 2.

Processing when the input characters among the step S13 of Fig. 2 can not be discerned is as shown in Figure 6.At first, show below indication: because the identification of handwriting input literal is please imported (step S51) once more with not existing in the database 11 and the corresponding literal of handwriting input text handwriting.Afterwards, the indicated number of step S51 judges whether to have passed through the stipulated time (for example 4 seconds) after finishing, and is judged as when not passing through the stipulated time, gets into step S53, judges whether the user has carried out returning the indication operation of handwriting input.

Otherwise, if judge among the step S52 when having passed through the stipulated time, entering step S57 as shown in the figure, the handwriting input text handwriting of input before the cancellation, the step S1 through step S58 returns Fig. 2 carries out new handwriting input and handles.Get into step S57 when the user has carried out returning the indication operation of handwriting input among the step S53, cancellation handwriting input character and graphic, the step S1 that returns Fig. 2 through step S58 carries out new handwriting input to be handled.

And; When judging that by step S53 the user does not return the indication operation of handwriting input; Get into step S54 and judge whether the user has carried out the indication operation of change character input method; If when judging the operation indication of not changing input method, judge through step S59 whether the user carries out further handwriting input (adding pen) operation.

If judge here when the user has carried out further handwriting input; The user does not return the indication of handwriting input in the i.e. stipulated time after the indicated number of step S51; And the user also indicates the change character input method, when the user has carried out handwriting input further under this state, proceeds handwriting input owing to meaning; Therefore return the step S2 of Fig. 2, hand-written input characters person's handwriting is detected the not enough processing of input space action afterwards repeatedly.In addition,, return step S52, carrying out the later processing of step S53 before repeatedly through the stipulated time if judge when the user does not carry out handwriting input further among the step S59.

Otherwise, if judge among the step S54 that the hand-written book text handwriting (step S55) of input before the cancellation got into step S56, changes to the indicated input method of user (like spelling input method) when the user had carried out the operation indication of change character input method.

Processing during the non-selected candidate character of the step S14 of Fig. 2 is as shown in Figure 7, judges after the handwriting input stops whether to pass through the stipulated time for example 4 seconds (step S61) at first.Here be judged as when having passed through the stipulated time, eliminate through the handwriting input text handwriting of step S66 input before, the step S1 in that step S67 returns Fig. 2 carries out new handwriting input and handles.

On the contrary; In step S61, judge when also not passing through the stipulated time; Step S62 judges whether the user has carried out returning the indication operation of handwriting input, is judged as when having carried out this indication operation, equally as previously mentioned; Cancellation handwriting input text handwriting in step S66 is returned the step S31 of Fig. 2 by step S67.Otherwise; Be judged as when the user does not return the indication operation of handwriting input among the step S62; Judge by step S63 whether the user has carried out the indication operation of change character input method; Here be judged as when having carried out change indication operation, eliminate the handwriting input text handwriting, get into step S65 and change to other input methods by step S64.When judging the indication operation of not changing, return step S61, to carrying out before the later processing of step S62 repeatedly through the stipulated time by step S63.

The handwriting character inputting device of embodiment of the present invention carries out action for example shown in Figure 8 and handles according to the motion flow of aforesaid Fig. 2～Fig. 7.In Fig. 8 to Figure 11, symbol 51 expression handwriting input portions (the handwriting input detecting element 2 of Fig. 1 and handwriting input display part 3), symbol 52 expression candidate character display parts, the literal display part is confirmed in symbol 53 expressions, the menu frame of symbol 54 expression handwriting input portions 51.In these figure, menu frame 54 is not with the outstanding physical frame of frame shape, but the outer peripheral boundary line of the input area of the real zone of expression handwriting input display part 3 and handwriting input detecting element 2.Therefore; The contact position coordinate of exporting by the touch-screen of handwriting input detecting element 2; Handwriting input text handwriting menu frame contact detecting element 24 shown in Figure 1 detects finger or pen has contacted the position that coincides with above-mentioned boundary line, contacts with the limit of menu frame 54 thereby detect the handwriting input text handwriting.But the above-mentioned boundary line that constitutes menu frame 54 also can be set in outward flange or the outer peripheral of input area of handwriting input detecting element 2 of the viewing area of handwriting input display part 3 and locate slightly in the inner part.

Fig. 8 is a situation about having embodied when finally wanting " win " word shown in handwriting input Fig. 8 (d).In Fig. 8 (a), embodied after having imported the part that is positioned at this literal top in the handwriting input portion 51 state when not having handwriting input to want the input space of input characters lower part.

In the stage shown in Fig. 8 (a); Be displayed on as the result who carries out literal identification according to the handwriting input text handwriting and occur institute in the candidate character on the candidate character display part 52 and hopes " win " word of importing, so be necessary to carry out handwriting input further.Shown in Fig. 8 (b), the user carries out the indication that this handwriting input text handwriting moves to the top is operated through drag operation.That is, shown in Fig. 8 (b), sliding above by lower direction in the handwriting input portion 51, the handwriting input text handwriting that is shown is moved to the top with finger.At this moment, the drag operation detecting element 41 of manual adjustment portion 39 shown in Figure 1 detects above-mentioned slide, through display position body adjustment part 35 in menu frame 54 with the handwriting input text handwriting to above move and show.Simultaneously, display size adjusting portion 42 dwindles demonstration with the handwriting input text handwriting in for example 60% regulation ratio.Like this; When the user carries out operation that the display position of handwriting input text handwriting regulates; Display size adjusting portion 42 is ratio according to the rules; Perhaps, enlarge/dwindle this literal figure automatically, more easily add an input operation thereby be convenient to the person of utilization for this handwriting input text handwriting is become prescribed level.In addition, the demonstration size of the expansion/minification of handwriting input text handwriting or this handwriting input text handwriting also can be carried out suitable setting through display size adjusting portion 42 by the user.

As a result, shown in Fig. 8 (c), this handwriting input text handwriting moves and is dwindled demonstration to the top of handwriting input portion 51.Therefore; Owing to a space of adding that below above-mentioned handwriting input text handwriting, forms; The user adds pen and has imported the person's handwriting in the frame of broken lines shown in Fig. 8 (d) afterwards, and the recognition result that adds the handwriting input text handwriting behind the pen is shown on the candidate character display part 52, and the user selects through touch operation etc. general candidate character " win " word wherein; Thereby confirm as the handwriting input literal, on definite literal display part 53, show this literal afterwards.

Fig. 9 is a situation about having embodied when finally wanting " beam " word shown in Fig. 9 (c), Fig. 9 (d) of handwriting input.In Fig. 9 (a), embodied after having imported the part that is positioned at this literal top in the handwriting input portion 51 state when not having handwriting input to want the input space of input characters lower part " wood ".In the stage shown in Fig. 9 (a); Be displayed on as the result who carries out literal identification according to the handwriting input text handwriting and occur institute in the candidate character on the candidate character display part 52 and hopes " beam " word of importing, so be necessary to carry out handwriting input further.But; The user is at a loss owing to the input space is not enough and causes handwriting input to stop; Afterwards; When waiting the selection operation that adds pen operation and candidate character that do not carry out the handwriting input text handwriting in the stipulated time or other operations in 7 seconds, detect this situation through stipulated time detecting element 25 after stopping by the handwriting input of Fig. 1 after, shown in the step S2 (the step S22 of Fig. 3) of Fig. 2, carry out the not enough judgement of the input space.So; Follow motion flow based on step S42～step S44 of Fig. 5; Judge that by identification adjustment parts such as handwriting input text handwriting radicals by which characters are arranged in traditional Chinese dictionaries 38 this handwriting input text handwriting of having imported is the high character and graphic of probability that is used as part of Chinese character (top); The result is shown in Fig. 9 (b); Through display position adjustment part 35 in menu frame 54 with the handwriting input text handwriting to above move to show in, in the ratio of regulation above-mentioned handwriting input text handwriting is dwindled demonstration through display size adjusting portion 42.

Afterwards; On the space of vacating by moving of above-mentioned handwriting input text handwriting; The user adds pen and has imported text handwriting " wood " in the frame of broken lines shown in Fig. 9 (c), and the recognition result that adds the handwriting input text handwriting behind the pen is shown on the candidate character display part 52, and the user selects through selection operation etc. general candidate character " beam " word wherein; Thereby confirm as the handwriting input literal, be shown in like Fig. 9 (d) afterwards and confirm to show on the literal display part 53 this literal.

Figure 10 shows only to dwindle to handle through the 42 pairs of hand-written input characters person's handwritings in display size adjustment part and forms the situation of adding an input space.Identical with Fig. 9 (a); Imported after the handwriting input text handwriting; Through the input space deficiency shown in the step S2 (the step S22 of Fig. 3) of Fig. 2 detect handle carry out the input space not enough detecting the time; Shown in Figure 10 (b), do not move the display position (center) of handwriting input text handwriting, only adjust the display size of handwriting input text handwriting, shown in Figure 10 (c), the handwriting input text handwriting is dwindled demonstration through display size adjustment part 42.The result is forming the space of adding comprise below the handwriting input text handwriting around the handwriting input text handwriting, the user can add an input characters person's handwriting " wood " below the handwriting input text handwriting in the frame of broken lines shown in Figure 10 (c).

In view of the above, shown in Figure 10 (d), the recognition result that adds the handwriting input text handwriting behind the pen is shown on the candidate character display part 52, and the user confirms candidate character " beam " word wherein through selection operation etc. as the handwriting input literal.No matter the handwriting input text handwriting is in the processing of dwindling that where can both carry out such handwriting input text handwriting of menu frame 54.

Situation shown in Figure 11 is identical with Fig. 8, the situation when being " win " word of finally wanting shown in handwriting input Figure 11 (f).In Figure 11 (a), embodied after having imported the part that is positioned at this literal top in the handwriting input portion 51 state during input space that do not have to supply handwriting input to want the input characters lower part.In the stage shown in this Figure 11 (a); Carry out the step S2 of Fig. 2; Being that input space deficiency shown in Figure 3 detects processing, but in this embodiment, is that outward flange frame area ratio through the handwriting input text handwriting carries out input space deficiency and detects processing among the step S23 of imaginary picture of primitive people 3.Thereby, under the state shown in Figure 11 (a), carry out the processing that detects that the outward flange frame ratio according to the handwriting input text handwriting shown in Figure 4 detects input space deficiency.This processed content is: as the handwriting input text handwriting outer rim area of the above-mentioned Fig. 1 of explanation during than detecting element 26 said, at first through outer rim detecting element 27 as Figure 11 (b) or as Figure 11 (c) shown in perhaps polygonal handwriting input text handwriting outer rim of such quadrilateral of setting encirclement handwriting input text handwriting.Then; Outer rim area calculating part 28 calculates the frame inner area of handwriting input text handwriting outer rim; The outer rim area utilizes the input picture area data 31 of storing in the storage part 30 than calculating part 29, calculates 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 the menu frame 4, the area in the handwriting input person's handwriting outer rim accounts for the regulation ratio when above, is judged as input space deficiency.

Afterwards; Identical with embodiment shown in Figure 9; Motion flow based on step S42～step S44 of Fig. 5; Judge that by identification adjustment parts such as handwriting input text handwriting radicals by which characters are arranged in traditional Chinese dictionaries 38 this handwriting input text handwriting of having imported is high as the probability that part of Chinese character (top) is used; Shown in Figure 11 (d) and Figure 11 (e), through display position adjustment part 35 in menu frame 54 with the handwriting input text handwriting to above move to show in, in the ratio of regulation above-mentioned handwriting input text handwriting is dwindled demonstration through display size adjusting portion 42.The result; Below above-mentioned handwriting input text handwriting, form and add a space; Shown in Figure 11 (f), add pen when having imported text handwriting or adding the pen input midway adding a space; Hope that the literal " wins " of input is shown in 52 last times of candidate character display part, the user is definite as the handwriting input literal with this literal " win " through selection operation etc., and is presented on definite literal display part 53.

In addition, though also there is following situation in Fig. 8 to Figure 11 and not shown: the input of handwriting input text handwriting as shown in Figure 8 midway, the bottom of the part bottom of " mouth " of below and menu frame 54 (above-mentioned boundary line) coincides.That is, can point during handwriting input or pen moves to the situation of the position that coincides with menu frame 54 each limit.In this case; In preceding method; Handwriting input text handwriting menu frame contact detecting element 24 detects handwriting input handwriting input text handwriting midway and contacts with menu frame 54; Thereby the judged result of the step S41 of the step S21 of Fig. 3 and Fig. 5 is " YES "; The handwriting input text handwriting menu frame contact position of Fig. 1 detect adjustment part 37 in menu frame 54 with the handwriting input text handwriting when the opposition side of institute's contact edge moves automatically, display size adjustment part 42 dwindles demonstration with the handwriting input text handwriting.As a result, shown in Fig. 8 (c), the handwriting input text handwriting that (an opposite side with contact edge) imported above menu frame 54 is dwindled demonstration, and its below forms a broad space of adding.Action afterwards is identical with embodiment shown in Figure 8, just repeats no more here.
