Nature in laptop computer, personal digital assistant (PDA) or the electronic equipment of mobile phone and convenience
Mechanism.Specifically, in conjunction with suitable character recognition engine, hand-written may be used for inputs at electronics
For the text of the such as various purposes of editor or word processing in equipment.
Handwriting input operate in, user can utilize such as indicate pin, pen or be only he/
The writing implement of her finger comes as write on plain paper, on the target device specific
Write region (such as, clipboard, touch screen or close to screen) write.Writing region
The track (hereinafter referred to " person's handwriting ") of upper equipments of recording, the most one or more character recognition
Engine performs suitable recognizer so that the person's handwriting recorded is converted into character.Exist some
Available recognizer or for such as based on structure recognition, such as hidden Markov model, nerve
The statistical model of network etc. carries out the product of character recognition.Due to hand-written naturality and facility
Property, in more calculating equipment, use hand-written more and more especially for mobile terminal.
Recently, it has been proposed that the most overlapping a kind of hand-written technology, this technology allows user at list
Individual writing the character that continuous writing in region is more than one, the character overlap of the most each input is front
On one character, as shown in fig. 1.Overlapping hand-written by using, user can with continuous writing,
Without the time out waiting the identification for each character.In like fashion, can not beat
The most smoothly write multiple character in the case of Duan, thus improve operating efficiency.Additionally, with
Thering is provided multiple region of writing to support that other hand-written solutions of continuous writing are compared, overlap is hand-written
What solution needs were relatively small writes region, and this is crucial for the equipment of finite size
's.
With reference to Fig. 1, it is shown that the high level schematic diagram of overlapping hand-written general process is described.As schemed
Showing, in overlap is hand-written, person's handwriting 102 needs being made up of the stroke of at least one character are divided into
At least one segmentation 104.This process is referred to as segmentation.Then, identify that engine is by one or more
Segmentation is converted into identified character 106 as output.In the prior art, perform on backstage to divide
Cut process.In other words, user will not be shown from the original overlap hand-written segmentation obtained, and
It is the most identified.Generally, under the support of particular language model, perform segmentation simultaneously and identify.
In like fashion, it is desirable to identifying engine person's handwriting based on input and the segmentation result that meets to provide most has
The character string of meaning.It is apparent that the final accuracy identified is largely dependent upon cutting procedure
Quality.
It is desirable that the character string identified should be strictly user originally wants the character string of input.
Unfortunately, although have been proposed for improving some solutions of the accuracy of the identification hand-written for overlap
Certainly scheme, but mistake is the most all inevitable.Segmentation and identification may all can
Run into mistake.In practice, when segmentation be character string that is correct and that identify be not correct time, if
Dry existing error correcting method, such as candidate list or rewrite single character, can work well
Make.But, cutting procedure occurs mistake and therefore causes in the identification string of output
In the case of mistake, traditional bearing calibration (such as, candidate list) is the most unsuccessful.
Such as, the type of the frequent fault in segmentation is referred to as unicursal mistake, wherein segmentation tool
There is an extra stroke or lack a stroke.According to statistics, at the most possible segmentation errors
In, unicursal mistake accounts for leading.There is also other kinds of segmentation errors as will be discussed.
In the case of there is mistake in segmentation, final recognition result is probably incorrect.So
In the case of, effective correcting identification result can be carried out by it now with technology does not exist user
Mode, and therefore, user must rewrite one or more character, this generates for operation effect
Rate and the negative effect of Consumer's Experience thus.

Improve the final accuracy identified.
Below with reference to accompanying drawing, embodiments of the present invention are described.Will be appreciated that, although following
Referring especially to Chinese character only certain exemplary embodiments of this invention will be discussed, but the scope of the present invention
It is not limited to this respect.Embodiments of the present invention are equally applicable to be suitable for overlapping hand-written any
The character of language.
As it has been described above, Fig. 1 shows the high level schematic diagram of the overlapping hand-written general process of explanation.?
In prior art, user is not shown the intermediate object program of segmentation.On the contrary, according to the enforcement of the present invention
Mode, can present to user and be revised such segmentation result by user, i.e. by segmentation
Hand-written the obtained one or more segmentations of original overlap, this will be described in detail below.
Fig. 2 shows the method 200 in overlapping hand-written middle use according to the embodiment of the present invention
Flow chart.As it can be seen, the method 200 starts at step S205, wherein user is shown
Show by overlapping hand-written at least one the obtained segmentation of segmentation.This at least one segmentation be such as from
Overlapping hand-written execution cutting procedure can be obtained with the segmentation module generating one or more segmentations
?.Should be appreciated that and such as can want to correct the word identifying as user when user asks
Symbol string in wrong time show this segmentation.Additionally or alternatively, segmentation can be with the final string identified
The most automatically show.In some embodiments, segmentation can be shown via in such as Fig. 5
The graphic user interface gone out shows, discussed more fully below.
Segmentation is used as the ultimate unit of successive character identification, and therefore should exist with as above
Single and whole character ideally is corresponding.Segmentation is made up of one or more strokes.As
Term used herein " stroke " refers to basic and inseparable key element of character or segmentation.
Should be appreciated that in step S205, can revise or editable mode shows at least one
Individual segmentation.I.e. so that user can select and then handle segmentation one or more strokes or
The whole segmentation of person.For this reason, it may be necessary to the positional information of segmentation stroke.Such information can be from previously
Cutting procedure in obtain.As known in the art, when performing segmentation to the overlap of user is hand-written
Time, for each segmentation obtained, no matter the special algorithm used, bag can be determined
The positional information of each stroke being contained in this segmentation.In other words, based on cutting procedure, each pen
The positional information drawn can be used for further using, such as, the selection of stroke as discussed below or
Pickup.Therefore, for each point in person's handwriting, this segmentation belonging to point or stroke are to can determine that
's.
Additionally, the temporal information of each stroke is also obtainable.For example, it is possible to existed by record
The sequential write of the user of hand-written period obtains the temporal information of stroke.In practice, such as,
When the structure complexity of segmentation, user is likely difficult to be based only upon positional information and selects spy from segmentation
Determine stroke.Now, selecting in stroke, can individually or combining position information uses pen
The temporal information drawn.Such as, in a preferred embodiment, stroke can be drawn under each segmentation
Timeline so that user can select a part for timeline, and then selects in segmentation
Corresponding one or more stroke.For selecting stroke or portion based on position and/or temporal information
Other replacement schemes divided also are possible.
Should be appreciated that any currently existing or exploitation in future method may be used for performing overlap
Hand-written segmentation, therefore can obtain position and/or the temporal information of stroke in a different manner.
The scope of the present invention is not limited to this respect.
It follows that in step S210, receive the request for correction segmentation.User find as
In step S205 in the case of the one or more mistakes in the segmentation of display, if he/her can be with
Dry mode initiates correction request.Then, in step S215, receive in response at step S210
The request arrived, revises at least one segmentation to obtain at least one new segmentation.To beg in detail below
Opinion step S210 and the operation of S215.
In a preferred embodiment of the invention, in step S205, user can be pre-via one group
Definition action receives request, and can correspondingly carry out repairing segmentation at step S210
Change.Fig. 3 A-3F shows some typical actions that may be used for request correction segmentation.
With reference to Fig. 3 A, in some cases, cutting procedure may be uncomfortable by the person's handwriting of single character
Locality is divided into the segmentation of more than one separation.Such as, as shown in fig. 3, user wants
It is " bright " by a Chinese character of overlapping handwriting input.But, in segmentation, this is single
The person's handwriting of character is divided into two independent segmentations, the first segmentation 310 " day " and the second segmentation
" moon ".In order to correct such mistake, according to certain embodiments of the present invention, in method
At step S210 of 200, user can ask to revise this segmentation in the following manner.
First, user can such as by use instruction equipment (such as pen, instruction pin, finger or
Mouse) or carry out in the frame of the first segmentation 310 or near it by pressing specific button
Click on and select or pick up the first segmentation.Then, it is allowed to user is by the first selected segmentation 310
Drag to the predefined neighborhood of the second segmentation 312, i.e. drag in the first and second segmentations 310
With the distance between 312 is less than the position of predefined threshold distance.As response, such as Fig. 3 A
Shown in, when the first and second segmentations 310 and 312 are combined as segmentation 314 " bright "
Amendment will be performed.Should be appreciated that above-mentioned action is only or illustrative, and other actions are also
It is possible.
On the other hand, another type of segmentation errors is exactly contrary with situation as shown in Figure 3A,
Wherein, during splitting, the person's handwriting of two or more characters separated is combined as list improperly
Individual segmentation.Fig. 3 B shows such example.In this example, user wants to input in two
Chinese character " day " and " moon ", but segmentation engine generates single split 320 " bright ".According to
Embodiments of the present invention, such mistake can be by performing again to split to the segmentation in discussing
Correct.User can ask again to split by segmentation carries out predefined action.One
In a little embodiments, predefined action can be such as double-click, long by or any other is suitable
Action.As shown in Figure 3 B, user can carry out predefined action (example to segmentation 320 " bright "
As, double-click).Then, by using position and the temporal information of stroke relative, can as response
To perform again to split so that segmentation 320 is divided into a lot of segmentation (showing shown in figure 3b
Example is two segmentations 322 and 324).Should be appreciated that double-click only may be used for request weight
The newly illustrated examples of the predefined action of segmentation, and other actions is also possible.
Fig. 3 C shows the situation similar with Fig. 3 B, wherein during splitting, two or more
Individual segmentation is combined into single split inadequately.But, different from Fig. 3 B, some combinations
Segmentation is very simple, and each is formed (such as, only one or two by several strokes
Individual stroke).According to the embodiment of the present invention, now, user can select by by this part
Drag to predefined region, such as dummy section, make the part drawn separate with segmentation simply,
Rather than call segmentation module perform again to split.
Term " part " as used herein refers to of the segmentation being made up of one or more strokes
Point.Should be appreciated that the selection to described part can complete by selecting its stroke, and right
The selection of stroke can complete by utilizing its position and/or temporal information, and this information can be from
Fragmentation procedure as above obtains.Such as, as any clicked on stroke, can select
This stroke.
Continue the example of Fig. 3 C, after selecting and dragging to predefined region, can be from original point
Remove the part operated in Duan, and new segmentation will be obtained based on this part.So,
One segmentation is divided into two, and this process can repeat before result is correct always.
Specifically, as shown in FIG. 3 C, Chinese character " people " and Chinese fullstop "." person's handwriting quilt
It is combined as a segmentation 330 mistakenly.Now, first user can select the stroke of fullstop, and
And then selected stroke is dragged in white space.As response, by the segmentation from combination
Remove in 330 stroke ".", only leave " people ".Additionally, will generate by the part group dragged
The new segmentation 334 become.Result is, it is thus achieved that segmentation 332 " people " and 334 "." the two
The segmentation separated.It is to be understood that, although the part drawn shown in Fig. 3 C only comprises one
Stroke, but embodiments of the present invention apply also for the part that is made up of multiple strokes.
Another type of segmentation errors relates to the order of two or more segmentations.With single character
Hand-written difference, when utilize overlapping hand-written time, user often wants to once input multiple character, such as,
Phrase or even sentence.Therefore, recognition result is it should be ensured that not only each and each character be just
Really property, it is also to be ensured that the suitable order of character string.Such as, with reference to Fig. 3 D, user thinks originally
Want inputting chinese phrase " Ching Ming Festival ".But, cause due to clerical mistake or the segmentation errors of user
Segmentation 342 " bright " and 340 " saving " are reversed.According to the embodiment of the present invention, Yong Huke
With such as by select segmentation and dragged to the position in fragment sequence ask correction point
The order of section.Then, this segmentation order in the sequence will be changed based on target location.Tool
Body ground, as shown in fig.3d, user selects segmentation 340 " saving " and is dragged to segmentation
Position after 342 " bright ".As response, the order of segmentation 340 and 342 is changed.?
In some other embodiments, position segmentation dragged in such as white space also can result in
The rearrangement of this fragment sequence.
With reference now to Fig. 3 E, it is shown that another example of segmentation correction.In this example, segmentation
The stroke (vertical stroke or " Shu ") of 352 " states " is assigned to the second segmentation improperly
350 " in ".That is, segmentation occurs unicursal mistake as above.Result is, segmentation
350 " in " how one, and segmentation 352 " state " has lacked one, this be likely to cause right
The identification mistake of two segmentations.According to the embodiment of the present invention, user can be in the following manner
Request correction is to process such segmentation errors.
Permission user selects the part of the incorrect assignment of the first segmentation, and this part may comprise one
Or multiple stroke.Then, the selected part in the first segmentation can be dragged to this part should
Predefined neighborhood when the second segmentation belonged to.In response to such action, by execution to first point
Section and the amendment of the second segmentation so that position based on such as stroke relative and temporal information are by institute
The part selected removes from the first segmentation and adds the second segmentation to.Specifically, such as Fig. 3 E
Shown in, user can select the vertical stroke in segmentation 350, and is dragged to segmentation
The predefined neighborhood of 352.In like fashion, it is thus achieved that the new segmentation 354 and 356 of two amendments.
In practice, it has been found that the stroke being easiest to mistake is two adjacent character " border " places
Those strokes, because such stroke is assigned to another point during being most likely at segmentation mistakenly
Section.Such as, one or more strokes of the beginning of segmentation may be assigned to immediately preceding this segmentation it
A front segmentation (such as, Fig. 3 E).Similarly, last or multiple stroke of segmentation
Often it is assigned to a segmentation after the segmentation discussed.Embodiment party according to the present invention
Formula, in order to preferably process such common situations, it is provided that specific action is to allow user
Be easier to and select exactly character beginning or last stroke.The example of such action
It it is shake.For example, it is possible to pass through to carry out clicking on and then rapidly to moving to left in the frame of segmentation
Move one or more strokes of the beginning selecting this segmentation, and can be by carrying out a little in frame
Hit and be promptly moved right to select last one or more strokes.As mentioned above, it is considered to
To a segmentation, lead due to the availability of temporal information (that is, sequential write) of each stroke
Cause can select that start or last one or more strokes.Certainly, for selecting opening of segmentation
Other actions of that begin and/or last stroke are also possible.The scope of the present invention is not limited to this
Aspect.
Although note that and show unicursal mistake in fig. 3e, but the embodiment party of the present invention
Formula is applicable to the more than one stroke of segmentation and is assigned to the situation of another segmentation mistakenly.
With reference to Fig. 3 F, according to the embodiment of the present invention, it is also possible to allow user by one or many
Individual stroke adds existing segmentation to.Sometimes, possibility is caused due to clerical mistake or the segmentation errors of user
Miss one or more strokes of character.Therefore, compared with the character that user initially wants input,
This segmentation may lack one or more stroke.In another case, user may wish on one's own initiative
Change input.In either case, any existing segmentation can be added a part by user
(that is, one or more stroke) rather than the most again key in.As response, can be based on
Segmentation in discussion and part generate new segmentation.As shown in this Fig. 3 F, by segmentation
360 " people " adds stroke, can generate by segmentation 360 " people " and the part " " added
Another segmentation 362 " greatly " of composition.
From described above it can be seen that work as request segmentation timing so that user can select to comprise
The specific part of one or more strokes or whole segmentation.To this end, the action selected for part
Should be made a distinction by sufficiently clear with the action selected for segmentation.According to some of the present invention
Embodiment, can realize this differentiation by the persistent period pressed or click on.Such as, short press
Or short click can be corresponding with the selection of stroke, and long by or the long selection clicked on whole segmentation
Corresponding.And for example, it is provided that option that user can be arranged or labelling.If this option or mark
Note is arranged to the first state, then action is to be interpreted as part selection.On the other hand, if selected
Item or labelling are arranged to the second state, then action will be used for segmentation selection.These are only
Illustrated examples.Can use for distinguishing the selection to part and appointing the selection of whole segmentation
What he mechanism.
Should be appreciated that action as above is configurable.That is, user can be according to him/her
Preference and/or the state of equipment add new action, removing action and/or revise existing dynamic
Make.Alternatively or additionally, it is also possible to by user's configuration various parameters relevant to action, all as above
The predefined neighborhood (distance threshold) stated, predefined region and/or predefined position.
Additionally, such as those skilled in the art of the present technique it should be understood that Fig. 3 A-3E illustrate only basis
Embodiments of the present invention for split some of the action of correction and corresponding operating illustrative and
Nonrestrictive embodiment.In view of above-mentioned teaching, those skilled in the art will think easily
To other actions for asking segmentation correction.Additionally, the interactive means in addition to action is permissible
For asking correction segmentation.For example, it is possible to be used separately or in combination as button, soft key and under
Draw the such control of list to input correction request.And for example, user can directly key in specific pre-
Fixed order is to initiate request.The scope of the present invention is not limited to these aspects.
Return Fig. 2, at step S220, during revising, highlight the part operated
Or segmentation.By highlighting the element operated, user can always know about mutual focus,
And avoid obscuring during revising.Highlight and can enter by many different modes
OK.For example, it is possible to change the color of element, profile, shade, font and/or the size of operation.
Alternatively or additionally, animation effect can apply to part and/or the segmentation operated.
With reference to Fig. 4 A-4B, it is shown that example according to the embodiment of the present invention, wherein pass through fish
Eyelens highlights the part or segmentation operated.In the example shown, send out as user
When playing the operation to specific part (Fig. 4 A) or segmentation (Fig. 4 B), just will show in flake
Part or segmentation in operation.Such as, according to part or the motion of segmentation of operation, in the amendment phase
Between can move flake.In addition to location, can also be dynamically updated at flake during handling
The content of interior display.Such as, in example as indicated in figure 3e, when user's first-selection selects to divide
During the stroke of section 350, segmentation 350 and selected stroke be included in flake, may simultaneously
The change of the color of the stroke being allowed a choice.While dragging to segmentation 352, can be at flake
In highlight selected stroke.Finally, when stroke and segmentation 352 are combined, will be fish
The segmentation obtained is shown in Yan.Should be appreciated that flake is only illustrated examples, and can be in conjunction with
(such as, color change, such as institute in Fig. 4 A-4B for other effects that highlight one or more
Show) use.
Shall also be noted that because user can select to enable/disable the prominent of the element that operating
Display, so step S220 is optional.Additionally, it can be configurable for highlighting effect.
That is, user can according to his/her hobby or equipment state add new effect, remove existing
Effect and/or configure various relevant parameter.
It follows that in step S225, identify that at least one obtained in step S215 is new
Segmentation, in order to export one or more character.Then, the method 200 terminates.As it has been described above,
Any existing or later exploitation recognition methods may be used to segmentation is converted into character, and
The scope of the present invention is not limited to this respect.Additionally, because in some applications, represent that user's is former
The segmentation of beginning person's handwriting can be stored and directly be used in the case of nonrecognition, so step
S225 is optional.The example of such application is writing practising application.
Fig. 5 is shown suitable in putting into practice embodiments of the present invention graphical user circle used
Face (GUI).According to certain embodiments of the present invention, GUI 500 can be with method 200
It is used together, and can such as be generated by the device described below with reference to Fig. 6 and Fig. 7
With present.
As it can be seen, graphic user interface 500 include editing area 505, candidate characters region 510,
Segmentation area 515, write region 520 and control area 525.In operation, Yong Huke
To write multiple character in an overlapping manner in writing region 520.It is then possible to perform to
