Embodiment
Below in conjunction with accompanying drawing, describe the present invention.
Fig. 1 is the process flow diagram of the method for writing words on touch-screen of the embodiment of the present invention, and as shown in Figure 1, the present invention's method of writing words on touch-screen comprises the following steps:
Step 101: set up the lteral data storehouse of writing words, set up writing words database.In lteral data storehouse, include the various grapholects for user's writing exercise, as Chinese character, Japan and Korea S's word, letter word etc.Each grapholect in lteral data storehouse, by at least one standard stroke, formed, each standard stroke at least comprises normal structure property value and standard shape property value, and described normal structure property value comprises: the presentation direction of writing sequencing, stroke between stroke, the stall position of stroke, stroke return pen, stroke with vigour of style in literary composition degree etc.; Described standard shape property value comprises: the profile of stroke, the ratio between stroke etc.
Mainly paste as user's exercise in lteral data of the present invention storehouse, so the word that this article numerical data base is included can be calligraphist's copybook, as grapholect, can be that the conventional font of some words is as the regular script in Chinese character, the Song typeface, running hand, cursive script etc.Important stroke for each word in lteral data storehouse, arranges some informations, to carry out when character calligraph is practised pointing out user user, practises instructing or wrong writing style being corrected.
In lteral data storehouse, also for each grapholect arranges information, when receiving user writing, export corresponding information, described information comprises: points for attention during stroke input, as needs when finishing, time pen, start writing in time during in cross break etc., these points for attention are that this word writing under certain font requires and handwriting skills; Rectification prompting while input error being detected in stroke input process, in user's input process, according to current detected stroke person's handwriting situation, set corresponding information, as starting writing when thinner compared with light and stroke, user point out user to go into overdrive, and stroke points out user to reduce while having gone out Chinese word stroke region, lteral data storehouse compared with extra coarse to use vigour of style in literary composition degree, if there is the more important vigour of style in writing to change in stroke input process, point out user to notice that the vigour of style in writing changes before changing the vigour of style in writing being detected; The action prompt of next entering stroke, has write after certain unicursal of word, for next stroke, if desired special suggestion, after before detecting, unicursal is inputted, the input prompt of next stroke of automatic-prompting, the first stroke of a Chinese character point of following unicursal, sequential write etc.
Information can be the prompt text, animation of output, dynamic or static icon, can be also voice, sound equipment or change color etc.
It should be noted that, lteral data of the present invention storehouse needs to provide according to user's exercise completely, it can be the word of any font, as can include calligraphist Yan Zhenqing, the king legendary ruler of great antiquity, the first of the Three August Ones etc. people's copybook, as standard Chinese character, also can include the handwritten form etc. of English alphabet, English word as grapholect.
Step 102: transfer grapholect to be write from lteral data storehouse, receive user according to the word to be compared of described grapholect input.The information that user provides according to lteral data storehouse, select the grapholect template of writing exercise, choose certain grapholect of writing exercise, " copybook " as writing words, be shown to the reference of facing note as user on display screen or imitating note, also after can reaching at user's writing practising certain skill level, to user, do not show, directly according to user's stroke input, carry out the output of information.In order to make user's entering stroke have thickness to change and dynamics conversion, promote user and experience, the present invention selects Multi-touch screen as writing screen.
As a kind of means that realize, after user's selected " grapholect ", the region that this " grapholect " write is also immediately by default, like this, can facilitate system whether " grapholect " the corresponding stroke in user's entering stroke and lteral data storehouse is coincide and judged, meanwhile, also can on Multi-touch screen, show simultaneously a plurality of " grapholects " and for user's writing exercise region, to realize the writing practising of accepting multi-user on a Multi-touch screen.User can carry out writing practising by lettering pen etc. on Multi-touch screen, to realize thickness and the dynamics of stroke, changes.For different " standard Chinese characters ", can apply different writing implements, when carrying out Chinese practice, the available pen with writing brush character is inputted, and during for the exercise of letter word, can apply conventional hard lettering pen at present and input.
Step 103: receive user's stroke input, stroke to be compared and the described standard stroke of user's input are compared, obtain comparative result, export comparative result and corresponding information to user.When user writes on Multi-touch screen by lettering pen, processor obtains user's the stroke person's handwriting of writing, structure attribute value and shape attribute value to the word of user's input compare with normal structure property value and standard shape property value respectively, obtain comparative result.The stroke to be compared of word and the corresponding standard stroke of grapholect that are about to user's input compare, judge that whether the sequential write of stroke is consistent with the stroke sequential write of grapholect in lteral data storehouse, if inconsistent, point out user input error, and point out user correct sequential write.The pixel of Multi-touch screen is connected with optical sensor, user by lettering pen when Multi-touch screen is write, optical sensor can detect the pixel that lettering pen covers Multi-touch screen, and processor extracts the written handwriting that these capped pixel regions are user.Also can know that lettering pen obtains user's written handwriting to the pressure of Multi-touch screen by pressure transducer, identical with the obtain manner of optical sensor, repeat no more here.When Multi-touch supporting dynamics perceptional function, can in lteral data storehouse, record the related request with vigour of style in literary composition degree and the information of stroke, as " pen " at stroke locates, can than common write rapidly great efforts some, and locate stroke " starting writing ", smaller than the common dynamics of writing rapidly.Processor can be write these and require to point out to user as information, and when user's entering stroke, extracts it and use vigour of style in literary composition degree, carries out record when inconsistent with lteral data storehouse parameter, and then prompting user notices that these write details.
If should write " horizontal stroke " after front unicursal, and user writing " erecting ", be stroke clerical error, point out user should write " horizontal stroke ", if should " horizontal stroke " have specific (special) requirements or have handwriting skills, be prompted in the lump user.Also need to judge that whether the presentation direction of user's entering stroke is correct, similarly, for " horizontal stroke ", sequential write from left to right and sequential write from left to right all can be realized input, if the sequential write of stroke is different from the sequential write that " grapholect " requires, need to point out user's input error equally, correct input sequence is prompted to user.Certainly, also need entering stroke track whether to coincide with the corresponding stroke of grapholect, for each entering stroke, if misfitted with the corresponding stroke of " grapholect ", can not reach and write requirement, coincideing with the corresponding stroke of " grapholect " is requirement the most basic in writing practising, why character calligraph has aesthetic feeling, collocation between line weight is considerable, therefore the stroke of user's input only reaches the input requirements of this stroke, could realize with the corresponding stroke of " grapholect " and coincideing, as some strokes in Chinese-character writing need to return pen or a pen, although can not embody these variations in detail from outline strokes, but for Chinese-character writing, be very necessary, the present invention can will return pen, the requirements such as pen of pausing are stored in lteral data storehouse as information.When the corresponding stroke of determining user's entering stroke and " grapholect " is thinner, can points out user to strengthen writing physical strength, and when the corresponding stroke of definite user's entering stroke and " grapholect " is thicker, can point out user to reduce writing physical strength.Rectification prompting while input error being detected in points for attention when information of the present invention also comprises aforesaid stroke input, stroke input process, the action prompt of next entering stroke etc.Here, information can word, the mode such as animation, dynamic or static icon, voice, sound equipment, color break-up exports to user.
Fig. 2 is lteral data storehouse Plays word and the information example schematic diagram of the embodiment of the present invention, Fig. 3 is lteral data storehouse Plays word and another example schematic diagram of information of the embodiment of the present invention, grapholect in figure be take Chinese character as example, how " " wherein, " benevolence ", " greatly ", " dog " are standard Chinese character, how user selects after the standard Chinese characters such as " ", " benevolence ", the input prompt of user's first stroke " slash " can be pointed out in its side, as shown in Figure 2, user writes by the order of 1,2,3,4,5 in diagram.User selects after the standard Chinese characters such as " greatly ", " dog ", when last stroke need be inputted in these Chinese characters, the input prompt of user's first stroke " right-falling stroke " can be pointed out in its side, and as shown in Figure 3, user writes by the order of 1,2,3,4,5 in diagram.In diagram 1,2,3,4,5 is also the monumented point of information output, at user's the vigour of style in writing, arrives before this point, to this point in user's output character database, stores information indicating.
The stroke track of inputting by lettering pen while practising for user, Multi-touch screen is according to the track overlay area detecting, select corresponding color to cover, and show to user, to realize user, each stroke of writing is had to a sense organ understanding, can directly differentiate the difference with " grapholect ".
After having received user's's a certain " grapholect " complete writing, each the stroke situation according to user's input, provides corresponding evaluation as provided concrete scoring etc., and notifies user by the mode of information.Determine the similarity between user's input characters and grapholect, help user to improve character calligraph power.When the stroke track of user input and the lteral data storehouse corresponding stroke of Chinese word reach certain similarity, think identical with lteral data storehouse Plays word.The definite of similarity be that structure attribute value and the shape attribute value of the word of user's input are compared with normal structure property value and standard shape property value respectively, to the sequencing of writing between the stroke of input characters and grapholect, the presentation direction of stroke, the stall position of stroke, time pen of stroke, stroke use vigour of style in literary composition degree, the profile of stroke etc. compares one by one, it should be noted that, when user is non-when imitating note and facing note or Freely input on Multi-touch screen, the stroke weight of user's input has suitable zooming in or out, the present invention is when identification user's stroke track input, need to the corresponding stroke in lteral data storehouse between have the convergent-divergent of corresponding proportion, to realize the accurate judgement to user's entering stroke.Can compare item to above-mentioned each respective weights is set, according to the structure attribute value of word and shape attribute value comparative result output one, pass judgment on mark or good and bad grade other metric.
