Description
Technical field
The present invention is broadly directed to handwriting input, and specifically, relate to and a kind ofly have the user interface that touches quick display screen and the hand-written equipment of electronics that can detect by the character script of user's handwriting input, and a kind of method that is used for handwriting input.
Background technology
At present, it is very general to use the hand-written equipment of electronics of for example portable/personal assistant (PDA), palmtop computer and portable terminal (for example mobile phone) to carry out handwriting input.In particular, very popular in the country in the Asian-Pacific area in the handwriting input on the portable terminal, China especially.The hand-written equipment of these electronics mainly relies on the input equipment of writing pencil for example and touches quick display screen.As those skilled in the art have known, the basic process of this handwriting input scheme is: the user uses writing pencil to want the character imported touching to write on the quick display screen, touch quick display screen and can detect the person's handwriting that writing pencil is write, thereby the identification user really wants the character imported.
At present, a plurality of companies that comprise Motorola, Sony-Ericson and Nokia have designed a lot of handwriting input schemes.With regard to the user writing zone that is allowed, roughly there are two kinds of forms in the handwriting input scheme: based on the text input method and the full frame text input method of frame.With the writing in the one or more virtual frame of region limits in touching quick display screen of terminal user, and the full frame input scheme of writing makes the user exempt from the restriction of edge circle, and the overwhelming majority of touching quick display screen screen zone is provided for writing based on the method for frame.
With regard to the character quantity that single can be imported, roughly there are two kinds of forms in the handwriting input scheme: monocase input method and multiword symbol input method.In the monocase input method, the character script that the user once writes is identified as a character, so the user once can only import a character; And in multiword symbol input method, the user once can import a plurality of characters, and the multiword symbol person's handwriting that user's one-time continuous is write can be identified as a plurality of characters.
For the monocase input method, practice widely followed is to estimate for the user provides character after importing a character each time, so the user has to stop pen and hang on the wait estimated result writing each character after, and selects in the middle of estimated result.Although this input method is very accurate aspect the identification of input, because of the mode of importing character by character, its recognition speed fundamentally is difficult to satisfy people's demand.And this does not meet general user's writing style, because when writing on paper, seldom the user can hang on after writing each character.And the normal conditions people always get used to carrying out continuous writing, are that unit pauses with phrase, phrase or short sentence for example.
This shows the writing style that multiword symbol input method is close to the users more with respect to the monocase input method.Yet for multiword symbol input method, a problem of making us perplexing is to be difficult to the multiword symbol person's handwriting of being write is carried out correct cutting apart.Generally speaking, in the multicharacter written handwriting process of identification, need this person's handwriting is divided into a plurality of components, a plurality of components of being cut apart are divided into a plurality of groups, the just corresponding character of group, then which character the identification user wants to import on the basis of this segmentation result.Usually, described cutting apart can be based on the gap between the different piece (for example radical of Chinese character) of gap between a plurality of characters of being write or single character.The difficult point of cutting apart often be the to identify the handwriting group of drawing of component, thus because probably do not notice making that the gap between the stroke in for example gap between the character and same character is suitable during user writing, cause drawing and organize a mistake.This situation takes place for writing especially easily of baroque Chinese character.Therefore as seen, if the stroke that multiword can be accorded with in the person's handwriting correctly is divided into single character, can avoid a lot of identification errors so.
In addition, in existing multiword symbol input solution, the shortage of man-machine interaction method and the deficiency of user interface design can not provide high-efficiency method for the correction of segmentation errors, and therefore a lot of user is discouraged because of frequent input error.And because in order to the shortage of the interaction capabilities of revising the Character segmentation mistake, recognition speed is very slow.
Therefore, the user interface and the electronic input apparatus of---especially multiword symbol input---has advanced part in the art to provide a kind of permission handwriting input more efficiently.

Embodiment
With reference to the accompanying drawings, accompanying drawing forms the part of embodiment in the description of following each exemplary embodiment, and illustrates by diagram in the accompanying drawings and can put into practice each exemplary embodiment of the present invention.Should be understood that and can use other embodiment, and can carry out without departing from the scope of the invention on the structure and function on modification.
Terminological interpretation
Person's handwriting: expression is being touched the traces of characters integral body of writing on the quick display screen by the input media of for example writing pencil.
Stroke: in the traces of characters that expression is write on touching quick display screen by the input media of for example writing pencil independent one is the basic component part of character.
The component of person's handwriting: expression is made of one or more strokes that are associated usually by cutting apart the part of the composition person's handwriting that person's handwriting obtains.
Segmentation result: when being illustrated in person's handwriting identification, person's handwriting is divided into one or more components, the respective components that wherein belongs to each character in the multiword symbol of being write can be divided into one group respectively, so that discern single character.This is divided into component by person's handwriting, and the result by component process gained in groups is exactly a segmentation result again.
For instance: write " woman ", " son " two characters on the quick display screen touching, represented the written trace of these two characters
Be person's handwriting, write five altogether, then each pen is a stroke.When identification, this written trace may be divided into a component
Discern, recognition result may be " good " like this; This written trace also may be divided into two components
Discern, recognition result may be " woman " like this.This shows that two kinds of different segmentation results cause two kinds of different recognition results.
Fig. 1 shows the synoptic diagram according to the hand-written equipment 100 of the electronics of the embodiment of the invention.As known in the art, the hand-written equipment of electronics that is used for hand-written character input generally comprises three parts: be used to detect touching quick display screen 110, be used for the input media 120 of written handwriting or input instruction and be used to carry out the treating apparatus 130 of data processing with the identification person's handwriting of the person's handwriting write.
Touching quick display screen 110 can be the display screen that is applicable to any commercial available types of handwriting input.Input media 120 can be pen, writing pencil, perhaps other lip pencil things---comprise user's finger or other body parts.Treating apparatus 130 can be the combination of CPU (" CPU (central processing unit) "), DSP (" digital signal processor ") or any other electronic programmable logical device or device.Certainly, the hand-written equipment of electronics can also comprise other device or parts, for example is used for the device of radio communication, the device that is used for wire communication, the device that is used to make a video recording, keyboard, loudspeaker, microphone or the like, but only describes the parts relevant with the present invention at this.
As known in the art, touch quick display screen 110 and not only be used for display visual information to the user, can also be used to receive hand-written character person's handwriting and instruction input.On most screen areas of this display screen 110, the user can want the character of importing or carry out instruction manipulation by using input media 120 to write it.Touch quick display screen 110 and can support multiword symbol input method according to of the present invention, and a plurality of characters can be write in a plurality of row of screen and (promptly support multirow to write).
Specifically, by on the display screen to be similar to the formal operations input media of on paper, writing 120, touch quick display screen 110 and can detect written handwriting, transfer it to electronic data and offer treating apparatus, by treating apparatus this person's handwriting is discerned.Finally, the character of being discerned---be that the user wants the character imported, can be used as text message and be imported in the various application programs of electronic equipment 100, for example message application (for example email, SMS, MMS etc.), calendar application, phone book application, or the like.For example in the example shown in Fig. 1, the final character of discerning " good " is present on the row of dotted line indication.
In addition, by on zones of different on the display screen 110 or window interface, clicking, rapping or dilatory input media 120, the user can be with writing pencil 250 as the interactive tool that is similar to the mouse in the computer, control the character input of electronic input apparatus 100 by following operation, for example in the candidate character list option, select, on display screen 110, be provided with cursor the position, select different control element (for example icon or button click) or the like.
Treating apparatus 130 with touch quick display screen and be coupled, can also can operate accordingly discerning from touching the detected written handwriting of quick display screen in response to the instruction that input media 120 is imported.
In traditional handwriting input process, written handwriting is displayed on and touches on the quick display screen when user writing, but in case the end of writing of writing one or more characters of starting to write promptly once, written handwriting will processing means substitutes by discerning the character that obtained (for example being presented at the character " good " on the represented row of dot-and-dash line among Fig. 1).In this case, in case user writing is started to write, the character script of being write before just can not checking again, She Ji a reason is that to touch the size of quick display screen usually very limited like this, not only need videotex to use on the quick display screen touching after writing, also need to show some control windows, for example candidate character list option, control icon, button or menu.And the person's handwriting that stays when writing usually can occupy the major part (for example over half) of touching quick display screen or almost whole; thereby write start to write after; if still touching reservation demonstration person's handwriting on the quick display screen; will reduce and write the space, also might be because cause confusion easily with the demonstration overlaid of text application and control window.
For multicharacter input, owing to once write a plurality of characters, and the multirow situation of writing (promptly once a plurality of characters of input are write respectively in the different row on touching quick display screen) especially, so person's handwriting is compared just bigger with the monocase input touching space occupied on the quick display screen.
According to the present invention, user interface---the person's handwriting query window 112 that can eject with indentation is set touching on the quick display screen.Person's handwriting is consulted the size of window 112 can be little more a lot of than touching quick display screen 110.When person's handwriting is consulted window 112 by At time of eject (being the situation shown in Fig. 1), the person's handwriting of just having write before presenting thereon, only with originally compare touching the quick display screen person's handwriting of writing of submitting a written statement to a higher authority, the size of the person's handwriting that window 112 is shown is by scaled---to touch quick display screen 110 little because person's handwriting is consulted the size ratio of window 112.When person's handwriting was consulted window 112 by indentation, it can be reduced into an icon, was in one jiao or side touching on the quick display screen 110, so that take the space of writing of touching on the quick display screen less as far as possible.Like this, the user can eject person's handwriting and consult window when needs are checked person's handwriting, and unwanted the time with its indentation.Thus, consult window by person's handwriting and can alleviate the limited space problem of touching quick display screen to a certain extent, make and to consult the person's handwriting of being write after having write character, do not influence the use of writing space and other window interface simultaneously.
In addition, clerical error can appear in user sometimes unavoidably to be needed to revise, and perhaps need revise for the identification error for the treatment of apparatus.And, might the user wish only to revise/revise some characters wherein but not all characters of being write.Like this,, discern, will help improving the accuracy and the recognition speed of person's handwriting identification so at amended person's handwriting if the user can consult the person's handwriting of being write and identify the handwriting and revise after once having write character.Therefore further, consult on the window 112, the function that the person's handwriting under just having write is before revised is provided for the user at person's handwriting.When person's handwriting is consulted window 112 by At time of eject, for example use input media 120, can directly consult on the window shown scaled person's handwriting is made amendment/revised, also can make amendment/revise this person's handwriting by other user's interface devices (for example keyboard) at this person's handwriting.And after-treatment device 130 will be at revising/revised person's handwriting renewal recognition result.For example, can be directly on shown scaled person's handwriting, add or the deletion stroke to revise clerical error.Again for example, can identifying---the person's handwriting segmentation result to be revised in the middle of some for the treatment of apparatus 130, this will describe in detail with reference to figure 3 after a while.
General handwriting input user interface can provide the candidate character list zone in order to improve the performance of user interface, wherein has a plurality of candidate characters to select for the user.These candidate characters are that the identification by treating apparatus 130 is handled, to the estimation of the corresponding character of the person's handwriting write and/or to association's prediction of the follow-up character that may import.Yet existing user interface only provides mostly with the multiword of being write and accords with the corresponding phrase of person's handwriting recognition result as a whole, and do not have other phrase as candidate's recognition result after the identification of multiword symbol.If the user has found identification error like this, can only check a plurality of candidate characters corresponding mostly with each hand-written character, therefrom select script to want the correct character of importing.
Therefore, another inventive arrangements of the present invention proposes candidate window to be set touching on the quick display screen 110, and candidate window comprises two parts: candidate's phrase hurdle 114 and candidate hurdle 116.The corresponding tabulation that comprises a plurality of candidate's phrases of multiword symbol person's handwriting that candidate's phrase hurdle 114 is used to present and is write, and can focus on any one character in any one candidate's phrase in described candidate's list of phrases in response to (for example directly click target that expection focuses on, cursor moved on the target that expection focuses on or the like that the mode that is fit to produces by keyboard, navigation bar etc. by input media 120) focusing instruction.So, on candidate hurdle 116, present the candidate character list corresponding with the character that is focused on.Like this, can directly from a plurality of candidate's phrases, select and originally want the correct phrase imported, if having in candidate's list of phrases.If there is not right-on phrase in the candidate list, then can select the phrase that is in the main true earlier, focus on then in this phrase on the incorrect single character, from candidate hurdle 116, select the script corresponding again and want the correct character imported with this single character.After a while, will describe in detail and utilize candidate window to carry out the embodiment of operations such as the selection of phrase and single character, deletion, rewriting with reference to Figure 4 and 5 in mode intuitively.
Below with reference in the description of 2-5 to embodiments of the invention, the example of portable terminal, but also can use the hand-written equipment of electronics of other type as the hand-written equipment of electronics, for example have the PDA that touches quick display screen, palmtop computer etc.In addition, will use the example of SMS message in the following description, it should be understood that other application also can be used to implement technical scheme of the present invention as the application of using the hand-written character input.
Fig. 2 a-e illustrate according to the embodiment of the invention eject as required and the indentation person's handwriting is consulted the audio-visual picture of window.As shown in the figure, write (Fig. 2 a) down a plurality of characters " happier " touch quick display screen 110 right side arrow 2A by clicking (Fig. 2 b) afterwards, can eject (Fig. 2 c) person's handwriting and consult window 112.The scaled person's handwriting that presents " happier " four characters of just having write on the window 112.Can will make this window indentation (Fig. 2 e) by clicking (Fig. 2 d) arrow 2B again.Should understand, control window 112 ejects and the mode (for example above-mentioned operation 2A/2B that clicks arrow) of indentation is not a key element of the present invention, also can use other control modes to control the ejection and the indentation of window 112, for example touch other menus or other buttons on the quick display screen by keyboard input instruction or use writing pencil click (comprising actions such as clicking, double-click, draw).
How Fig. 3 a-c for example understands at person's handwriting and consults corrections identified the handwriting on the window segmentation result and thereby the audio-visual picture of renewal recognition result.Shown in Fig. 3 a, consulting what presented on the window 112 at person's handwriting is the person's handwriting that has just touched " happier " four characters of writing on the quick display screen 110.Suppose, can be divided into six components according to this person's handwriting of person's handwriting dividing function, for example as shown in the figure each component respectively by frame in an empty frame.Possible, because " power " in the stroke of " more " and " adding " is leaned on nearerly when writing, thereby cause when person's handwriting is cut apart, " more " and " power " is divided in one group.Similar problem has also appearred in the person's handwriting for " soon " and " pleasure " two characters.So the phrase of estimating by recognition function at the beginning corresponding with this multiword symbol person's handwriting is " contain in the merit mouth ", the phrase of wanting originally to import with the user does not conform to fully.
Shown in Fig. 3 b, can use for example writing pencil, come the component of being cut apart is drawn group again by the pen type gesture.For example, a plurality of diversity that can will belong to same character by belt pen type gesture as shown in the figure lump together.In this embodiment, " power " and " mouth " is integrated into together and " adds " to form character, and the component of " soon " also is like this.Although not shown in the drawings, can indicate the situation in groups of component by usage flag, promptly which group is which component be divided in, make to component to draw group again more directly perceived.For example, can be along with drawing group again empty frame in the variation diagram, make be divided in component in same group by frame in same empty frame, distinguish different component group (being different characters) with empty frame.
After drawing group again, recognition result has become correct phrase " happier " from incorrect " contain the merit mouth ", shown in Fig. 3 c.Like this, consult window, can intuitively promptly revise the segmentation result of multiword symbol person's handwriting, obtain the user and want the correct character imported by person's handwriting.
Expect that easily the mode that character script is made amendment is not limited to form shown in Figure 3.For example, each component that can also use other pen type gesture will not belong to same character is separated, perhaps by a certain component of other operation deletion.
The pen type gesture of going in ring as mentioned herein is meant by writing pencil determines that in the geometric position of touching the mobile vestige on the quick display screen circle selects the operation of content, can use existing techniques in realizing.Conspicuous as ability and technician, the pen type gesture in the foregoing description is not a limitation of the invention, can operate by other yet component is divided into groups again or identified the handwriting and carry out other correction.
As previously mentioned, existing multiword symbol is imported user interface or is discerned, selects, revises or delete rewriting character by character, or the identification of whole phrase ground, selection, modification or deletion rewriting.Thereby multiword symbol input efficiency is very low.And technical scheme of the present invention both can obtain the recognition result for the whole phrase corresponding with multiword symbol person's handwriting, can obtain recognition result thus for corresponding single character, thereby both allowed the user that whole phrase is selected, revised or deletes, allow the user that rewriting is selected, revises, deletes or inserted to single character again.
For these features according to user interface of the present invention are described,, be that example illustrates with the flow process of handwriting input Chinese sentence " wish everybody Happy Spring Festival the Lantern Festival is happier " with reference to Fig. 4 a-u.
Shown in Fig. 4 a, submit a written statement to a higher authority and write the person's handwriting of " wishing everybody " three characters touching quick display screen.By the identification for the treatment of apparatus, in candidate's phrase hurdle 114 of candidate window, present candidate's list of phrases.Shown in Fig. 4 b, candidate's list of phrases comprises that two candidate's phrase clauses and subclauses " wish everybody " and " looking everybody ".When first entry be just the user want to import multiword symbol phrase the time, can continue to write and need not to pause (shown in Fig. 4 c), at this moment described first entry " is wished everybody " and is defaulted as correct phrase, presents as the text of content of short message.
If not being the user, the first entry of the candidate's list of phrases that presents in candidate's phrase hurdle 114 do not want the correct phrase imported, and correct candidate's phrase is positioned on other position of this candidate's list of phrases, then can select to select from candidate's list of phrases that correct phrase.Shown in Fig. 4 d-4f, on touching quick display screen, once write after the person's handwriting of (Fig. 4 d) following four characters " Happy Spring Festival ", can use the input media of writing pencil for example to select (Fig. 4 e) to come the deputy phrase of candidate's list of phrases " Happy Spring Festival ", present (Fig. 4 f) with text as content of short message.
If there is not the user to want the correct phrase of importing in the candidate's list of phrases that presents in candidate's phrase hurdle 114, then if not segmentation errors, can select earlier and the correct essentially identical option phrase of phrase, and then select single correct character or write single character again by candidate hurdle 116.Avoid writing again the trouble of whole phrase like this.
Shown in Fig. 4 g-i, on touching quick display screen, once write after the person's handwriting of (Fig. 4 g) following three characters " Lantern Festival ", " the no stomach joint " that can select to present in (Fig. 4 h) candidate's phrase hurdle 114, although this phrase that to be not the user want imports, comparatively near correct phrase---for example comprise all that three characters and the 3rd character " joint " they are correct.Shown in Fig. 4 i, cursor can be focused on above the character " nothing " in " the no stomach joint " from candidate's phrase hurdle 114, selected, so in candidate hurdle 116, present other candidate characters for character " nothing ", originally want the correct character " unit " imported comprising the user, so just can from the candidate characters hurdle, select correct character " unit ".
If still there be not the correct candidate characters corresponding in the candidate hurdle with this single character, then can delete this single character, to write again, Fig. 4 j-o shows this situation.Shown in Fig. 4 j and 4k, during the character in focusing on candidate's phrase " stomach ", in the candidate hurdle, there is not correct candidate characters, so can delete character " stomach " (operation to backspace key 118 that wherein relates to will be described in detail with reference to figure 5 (b) after a while).Only stay " unit's joint " (Fig. 4 l) like this in the text content of short message.Shown in Fig. 4 m-o, written character " night " again, and character " night " is inserted between character " unit " and " joint ".
If there is segmentation errors, may not approach candidate's phrase of correct phrase in candidate's phrase hurdle 114 substantially at all.So person's handwriting is consulted window 112 and can be ejected, checking the person's handwriting segmentation result, and on this window, the component of being cut apart is drawn group or other person's handwriting correction again, with the recognition result that has obtained to upgrade.Shown in Fig. 4 p-4u, the position (Fig. 4 p) that selection continues to write, and once write (Fig. 4 q) following four characters " happier ".Shown in Fig. 4 r and 4s, in the time of in finding candidate's phrase hurdle 114, may not approaching candidate's phrase of correct phrase substantially, determine it may is segmentation errors at all, consult window 112 so eject person's handwriting.Like this, can consult on the window at person's handwriting the component of segmentation errors is drawn group (Fig. 4 t) again.So, in candidate's phrase hurdle, demonstrate candidate's list of phrases (Fig. 4 u) of having upgraded, want the correct phrase of importing originally comprising the user.
The present invention attempts farthest to avoid again the trouble of stroke writing, for the situation of having to write again, can make handwriting input more convenient by the backspace key of once deleting whole phrase as required or once deleting single character because of clerical error as far as possible.Fig. 5 (a) shows the audio-visual picture according to the example of the whole phrase of deletion of the embodiment of the invention; Fig. 5 (b) shows the audio-visual picture according to the example of the single character of deletion of the embodiment of the invention.Shown in Fig. 5 (a), once write three characters " handwritten form " afterwards, the backspace key 118 in the candidate window is in
