Description

The continuous display packing of handwriting input and adopt the hand input device of this method

Technical field

The present invention relates to the handwriting input field, particularly a kind of display packing of continuous handwriting input and adopt the hand input device of this method.

Background technology

Electronic equipment with touch controllable function is more and more general, and present device based on touch-control, for example intelligent mobile phone, flat computer or notebook computer etc. have a touch-control input equipment function from strength to strength, the benefit of touch-controlling interface is to make things convenient for the user to import, the electronic equipment that this makes hand-write input function also thereby is widely used in touch-controlling interface is particularly stressed on the hand-held device easy to carry.

The contact panel size of hand-held device has limited touch-control input area, and this makes the method for handwriting input be subject to the area size in the handwriting input zone of contact panel.When the user carries out the stroke of inputting characters by handwriting by contact panel, be subject under the input area situation, if the user is when desiring on contactor control device a plurality of character of handwriting input continuously, tend to occur the overlapping situation of stroke track of kinds of characters, therefore, the user is if will avoid the overlapping demonstration of stroke, after all strokes of same character must being imported, and wait for that hand input device carries out identification, after the character of finishing to be identified disappeared to display screen, the user carried out the stroke input of character late again.Otherwise, the overlapping situation about being shown on the display screen of stroke track of a plurality of characters, the puzzlement that causes the user to import continuously will appear.

At present known have certain methods to attempt to solve the above problems, for example application number is that the Chinese invention patent disclosed method that CN200910055524.X, name are called " hand-written input system and method, electronic equipment " is the electric ink (display effect of handwriting input track) in the rolling handwriting input zone, allows the user carry out handwriting input in identical handwriting input zone constantly; Or, for example application number is CN201010583582.2, the method that name is called the Chinese invention patent exposure of " hand-written inputting method of multiword symbol continuous writing " is after judging whether current stroke belongs to identical characters earlier, again with the stroke color deepening of previous inputting characters by handwriting, in more detail, just must judge earlier current input stroke (finishing stroke input back) and import stroke and whether belong to same character, whether can according to judged result decision with the colour-darkening of stroke finishing if judging, before this method can cause judged result to occur, whether all strokes (current input stroke with imported stroke) are no matter belong to same character, all can have identical stroke display mode, so still can't effectively solve the disturbance regime of overlapping demonstration.Therefore when the user imports a plurality of character if desired continuously, the user waits for that with regard to being forced to stroke track (electric ink) rolling is finished or the judgement of wait character is finished, thus, though solve the problem of in limited handwriting area, importing hand-written stroke continuously, but when still the user being imported continuously, disturb because the overlapping demonstration of kinds of characters stroke causes vision, produce puzzlement on the fluency and the user operated.

In addition, known also have additive method to attempt to solve same problem, for example application number is that CN201110146057.9, name are called shown in the Chinese invention patent of " be used for eclipsed form write method and apparatus ", its disclosed method is that each stroke is apparent on the display screen up to regulation event (for example reaching default certain hour or default certain input stroke number) takes place, and fades away then; Or for example application number is that CN201110303577.6, name are called shown in the Chinese invention patent of " a kind of stroke gradual change blanking method and device ", its disclosed method is in every input new stroke once, all can carry out the gradual change elimination of hidden that different colours shows respectively to the historical stroke in each buffer area.

In addition, at present also promising solve overlapping continuously hand-written with cut apart effectively overlapping hand-written in order to each character and other characters are separated quite difficult problem, for example application number is CN201080068735.8, name is called shown in the Chinese invention patent of " method and apparatus that is used for overlapping handwritten stroke is divided into one or more groups ", its disclosed method is the stroke segmentation that is based upon under the identical characters, such method needs to collect the data of considerable stroke feature and training in practical application, just needs to spend many times and resource might be reached the effect that this invention is declared.

Above-mentioned mode provide allow the user can be in limited handwriting input zone input character continuously, and avoided that stroke is overlapping to be manifested, but such mode, particularly as user during with the less stroke of input in Chinese, the overlapping demonstration of kinds of characters stroke still can occur and cause interference in the demonstration, for example import " one by one " of " leaving one by one " continuously, or, with input in Chinese during than Multi strokes, same stroke disappears too early, and (stroke dissipates gradually light earlier, the process of Xiao Shiing again), for example the situation of input " leaving one by one " " leaving " occurs continuously, therefore still can't provide the user a good and interference-free handwriting input display interface.

Therefore, be necessary that a problem that solves is when how limited handwriting input zone cooperates user's continuous writing stroke to import one or more stroke on Touch Screen, when the stroke of input is overlapping, make the demonstration of current input stroke not be subjected to before having imported the demonstration influence of stroke, stroke shows overlapping interference during with a plurality of stroke of reduction user's continuous writing, and then the handwriting input fluency of raising limited area, this is the major issue that the anxious desire in present writing technology field solves.

Embodiment

The present invention proposes a kind of display packing of continuous handwriting input and adopt the hand input device of this method, when this method and apparatus can solve handwriting input before and after the stroke of the same character of input or the kinds of characters problem that when showing, the importer can be distinguished preferably.

In the technology of the known overlapping character of handwriting input, the method of stroke cutting is to allow character or stroke produce the core key technology of different display effects, but different cutting methods can produce different display effects, the technology that for example has is with the least unit of single stroke as the differentiation demonstration, makes different strokes have different display effects; And the technology that has is in conjunction with the character recognition technology, make kinds of characters have different display effects, the technology that also has is the correlativity of gathering the geometric properties of a series of input strokes, as the foundation of separating character stroke, accordingly to reach the effect that differentiation shows stroke.

For this reason, the present invention proposes a kind of display packing of continuous handwriting input, be used for showing stroke and the character of the character of importing when the Touch Screen inputing characters of hand input device, this method is specially adapted to the demonstration of overlapping character or stroke.

Fig. 1 is the steps flow chart synoptic diagram of the display packing of continuous handwriting input of the present invention.As shown in Figure 1, this method comprises the following step of carrying out successively:

Touch-control input during the stroke of step S1, sensing user handwriting characters generates current stroke track according to position of touch, and first display effect is set the display effect of current stroke.

Fig. 2 is the synoptic diagram of the Touch Screen of an embodiment.As shown in Figure 2, be set with a character input field 114 on the Touch Screen 110, this zone is used for the touch-control input of sensing user hand-written character, because multicharacter overlapping input is supported in handwriting input of the present invention, so this character input field is also referred to as reduplicated word input field 114.Reduplicated word input field 114 is preferably with certain cue mark and shows that at Touch Screen 110 cue mark for example is various lines, color lump etc., can come input character by hand-written so which position the user understands in.

According to preferred implementation of the present invention, the zone of reduplicated word input field 114 can be set by the user.For example, when default reduplicated word input field 114 is rectangle, when the user touches arbitrary angle of 114 4 corners, reduplicated word input field or after the user presses the frame certain hour of reduplicated word input field 114, but reduplicated word input field 114 enters adjustment modes at this moment, when the user pulls selected one jiao of center position near reduplicated word input field 114 and moves, just can dwindle the size of reduplicated word input field 114, on the contrary the user pulls one jiao of selected center position away from reduplicated word input field 114 when the moving size of scalable reduplicated word input field 114 then.

Among the step S1, when the user passed through Touch Screen 110 input characters, the reduplicated word input field 110 of Touch Screen 110 received the stroke of users' input.Specifically, the user touches with touching devices such as finger or felt pens and is positioned at the stroke that input character is come in reduplicated word input field 114 default on the Touch Screen 110, the corresponding continuous touch track of arranging chronologically of stroke, touch track can be determined by the coordinate of the pixel that is touched on the reduplicated word input field 110, therefore, corresponding continuous trajectory coordinates set of stroke.

Described reduplicated word input field 114 is for writing the touch input field of the hand-written stroke of setting according to Touch Screen 110 sizes in advance by the system of hand input device, and the user can be by touching described Touch Screen 110 input strokes in described reduplicated word input field 114.

Step S1 when accepting user input, on Touch Screen with the stroke of first display effect explicit user input.Usually, centered by the trajectory coordinates of this stroke, and show this stroke in the mode of lines, but different display effects can be arranged, for example, can wait to show with different line colors, thickness, brightness, contrast, continuity (solid line or dotted line), end points shape, transparency.

The coordinate set of step S2, the current stroke track of storage, and the starting point coordinate of current stroke track and terminating point coordinate.

Input has also shown a stroke in real time among the step S1, is current stroke, and by preceding described, this trajectory coordinates is a continuous coordinate set of arranging chronologically.According to user's order of the touch-control on Touch Screen when importing stroke, include the coordinate as super initial point coordinate and terminating point coordinate in the trajectory coordinates set of current stroke.

Step S2 stores the trajectory coordinates set of current stroke and starting point coordinate and the terminating point coordinate in the set of this trajectory coordinates thus.Complete stroke track comprises starting point (starting to write a little) and the terminating point (lifting a point) of stroke.

After current stroke is finished above-mentioned storage, if when having the input of new stroke to begin to import to produce new start to write, the stroke that stores the complete trajectory coordinate will no longer be regarded as current stroke, and be considered as the stroke (previous stroke) of previous input, and the stroke of new input then is considered as current stroke; Described " current stroke " is the complete stroke of not finishing or just finished input during the user imports.

Step S3, judge whether that according to default stroke cutting condition needs cut current stroke and previous stroke, cutting then continues execution in step S4 if desired, if do not need cutting, then execution in step S5.

Step S3 is mainly used in judging whether and current stroke and previous stroke need be cut." cutting " described here refers to visual differentiation, knows different strokes so that the user debates.

Owing to need not cutting when having only a stroke, it is not the stroke of importing first in the current incoming task that therefore default cutting condition at first will satisfy current stroke.If judge the stroke of current stroke for importing first, so directly be judged as and do not satisfy default cutting condition, can directly advance to step S5.

If be judged as current stroke when not being the stroke of importing first, then continue to judge whether to satisfy default cutting condition.Whether default cutting condition is according to the condition that whether is fit to current stroke and previous stroke are visually distinguished, just be fit to current stroke to be different from the condition that previous stroke mode is shown.

The present invention will be hereinafter description by specific embodiment come to carry out more specifically bright to stroke cutting condition.

Step S4, the display effect of previous stroke is set at other display effects that are different from first display effect.

This step S4 is concrete " cutting " step, namely when needs " cutting ", all previous strokes is shown with the display effect that is different from current stroke.

A kind of embodiment is, all previous strokes all adopt second display effect identical but that be different from first display effect to show.Other embodiment comprises, according to formerly cleavage to stroke classification display formerly.For example, the previous stroke of input is more early shown with more shallow color.

Described differentiation shows that processing is to make the stroke display effect of different group of strokes have stroke to be presented at color, thickness, brightness, contrast, continuity (solid line or dotted line), the end points shape, the difference of display effects such as transparency, for example, make the stroke color of first display effect of current group of strokes darker than the stroke color of second display effect of previous group of strokes, or making the stroke color of second display effect of previous group of strokes more shallow than the stroke color of first display effect of current group of strokes, it for example is that first display effect has different stroke color with second display effect that other differentiation shows, brightness, contrast, thickness etc. shows.

The track that step S5, the stroke display effect of setting according to above-mentioned steps show each stroke in real time then returns execution in step S1.

This step is the step that shows each stroke track at last at Touch Screen 110.According to the present invention, this step display is to show in real time, and namely the user shows the track of this stroke simultaneously when the current stroke of input, to reach the effect of what you see is what you write.

For making the purpose, technical solutions and advantages of the present invention clearer, below in conjunction with specific embodiment, and with reference to accompanying drawing, the present invention is described in further detail.

According to one embodiment of present invention, as shown in Figure 3, described reduplicated word input field 114 is divided into the district 1141 of starting to write and distinguishes 1142 with lifting pen, and the district 1141 of wherein starting to write is positioned at the upper left side of reduplicated word input field 114 and lifts the lower right that pen district 1142 is positioned at reduplicated word input field 114.Described default stroke cutting condition is: the starting point of current stroke (starting to write a little) coordinate is positioned at the described district 1141 of starting to write, and the terminating point of the last stroke of current stroke (lifting a point) coordinate is positioned at the described pen district 1142 of lifting.That is to say that step S3 is positioned at the district 1141 of starting to write at the starting point coordinate of current stroke, and the terminating point coordinate of the last stroke of current stroke is positioned at and lifted the pen district at 1142 o'clock, be judged as and satisfy stroke cutting condition.

According to a kind of preferred implementation, comprise a Jiu Gong district 116 in the described reduplicated word input field 114, this Jiu Gong district is divided by nine rectangle regions of three rows, three row and forms, and with the some rectangle regions in these nine rectangle regions as the district of starting to write, other rectangle regions conducts except the district of starting to write are lifted and are distinguished.

As shown in Figure 4, the row in Jiu Gong district 116 is divided into up, middle row is with descending, and row are divided into left column, middle row and right row, wherein, first rectangle region 1161 is positioned at up left column position, second rectangle region 1162 is arranged in up column position, the 3rd rectangle region 1163 is positioned at up right column position, the 4th rectangle region 1164 is arranged in the left column position of row, the 5th rectangle region 1165 is arranged in the column position of row, and the 6th rectangle region 1166 is arranged in the right column position of row, and the 7th rectangle region 1167 is positioned at descending left column position, the 8th rectangle region 1168 is arranged in descending column position, and the 9th rectangle region 1169 is positioned at descending right column position.

Fig. 5 A and Fig. 5 B have shown that two kinds are divided the preferred implementation of starting to write and distinguishing and lifting the pen district in the Jiu Gong district, represent the district of starting to write with the shadow region among the figure, and a district is lifted in the unshaded area representative.Show that as Fig. 5 A the described district of starting to write comprises first rectangle region 1161, second rectangle region 1162 and the 4th rectangle region 1164, and other rectangle regions are for lifting the pen district.Show in another embodiment, in order to make the stroke cutting better accurate performance can be arranged as Fig. 5 B, the described district of starting to write also comprises the 3rd rectangle region 1183, and other rectangle regions are for lifting the pen district.

Preferably, nine rectangle region sizes in described Jiu Gong district 116 are identical.

Jiu Gong district 116 can be virtual on Touch Screen 110, does not namely indicate at Touch Screen with color lump, lines, pattern etc.But preferably, nine rectangle regions in described Jiu Gong district 116 are shown in the grid wire in the reduplicated word input field 114 of Touch Screen 110, prompting user input position.

According to preferred implementation of the present invention, described default stroke cutting condition is: the starting point coordinate of current stroke is positioned at this district of starting to write, and the terminating point coordinate of the last stroke of current stroke is positioned at this and lifts pen district.

The size in described Jiu Gong district 116 and multiple setting means can be arranged at Touch Screen 110 and position, it both can be fixed, and also can be automatically to adjust according to the character of user's input.Because the user inputs character size can be subjected to different factor affecting, for example the thickness of felt pen influences character input size, or the number that is subjected to stroke influences, stroke more many input characters size can be big slightly, when surpassing reduplicated word input field 114, when just surpassing Jiu Gong district 116 sizes, this moment, Jiu Gong district 116 boundary dimensionss can be adjusted according to the stroke coordinate boundary value of the actual input of user, so can be greater than reduplicated word input field 114; Stroke is less, and then the user is easier to font control in reduplicated word input field 114, and this moment, Jiu Gong district 116 boundary dimensionss can be less than or equal to reduplicated word input field 114.

The shape of reduplicated word input field 114 is not limited to as Fig. 2 or rectangle shown in Figure 3, can also be ellipse or circle etc.At this moment, Jiu Gong district 116 still is preferably with reduplicated word input field 114 has identical geometric center, and the size in Jiu Gong district 116 then connects rectangle by the imperial palace of reduplicated word input field 114 or maximum boundary rectangle determines.

A kind of embodiment is that Jiu Gong district 116 is positioned at described reduplicated word input field 114, and is all fixing with respect to position and the dimension scale of reduplicated word input field.Because the major function of reduplicated word input field 114 is touch-control inputs of sensing user hand-written character, and usually with certain cue mark, for example various lines, color lump etc. are shown on the Touch Screen 110, can come input character by hand-written so which position the user understands in.According to general on Hard copy the custom of written character, the user can be accustomed to character is write in the indicating area, the square frame on the composition notebook for example, or near the indicating area, for example the printing lines on the notepad near, therefore, when the Dang Jiugong district is arranged in the reduplicated word input field 114, can make the 116 pairs of stroke cuttings in Jiu Gong district that reasonable localization effects can be arranged.The length of the length in described Jiu Gong district 116 and wide and reduplicated word input field 114 and wide ratio can be 0.3 * 0.3 (just the length in Jiu Gong district 116 and width be equal to reduplicated word input field 114 30%), 0.4 * 0.4,0.5 * 0.5,0.6 * 0.6,0.7 * 0.7,0.8 * 0.8,0.9 * 0.9, or 1 * 1, etc., the rest may be inferred.

Another kind of embodiment is that Jiu Gong district 116 overlaps with the maximum touch-control scope of Touch Screen 110.Maximum touch-control scope refers to can receive on the Touch Screen 110 All Ranges of user's touch-control input.When whole Touch Screen 110 can both receive the input of user's touch-control, then the Jiu Gong district can cover whole Touch Screen 110.In this embodiment, if reduplicated word input field 114 is positioned at maximum touch-control scope, then the size in Jiu Gong district 116 might surpass reduplicated word input field 114; If reduplicated word input field 114 is maximum touch-control scope, then Jiu Gong district 116 can not surpass reduplicated word input field 114.

Another embodiment is, the position in Jiu Gong district 116 and size can and be adjusted in real time according to user's hand-written touch-control input, aforesaid situation is had more perfect cutting effect, allows the user can be according to general Hard copy writing style input character.Although according to writing style, the user often writes character in the indicating area,, also tend to when the user writes exceed the indicating area some.Therefore, when reduplicated word input field 114 fixedly the time, the position in Jiu Gong district 116 and size are more preferably according to user's hand-written touch-control input and adjust in real time.In this embodiment, Jiu Gong district 116 has an initial position and size, i.e. the position of system default and size, and in the hand-written character input back that receives the user position and the size in Jiu Gong district are adjusted in real time.In one embodiment, the original dimension in Jiu Gong district 116 (long * wide) be reduplicated word input field 114 size 0.3 * 0.3 (long * wide) doubly, initially geometric center overlaps with the geometric center of reduplicated word input field 114.

According to a kind of preferred implementation, adjust the border in Jiu Gong district 116 according to the extreme value coordinate components in the coordinate set of current stroke track, make Jiu Gong district 116 cover current stroke.That is to say, when the current stroke of handwriting input exceeds current Jiu Gong district 116 regional, adjust the border in this Jiu Gong district 116 in real time, so that the stroke of the current input of Jiu Gong district 116 coverings after adjusting.Specifically, at the horizontal ordinate of Touch Screen being to the right positive dirction, ordinate upwards being under the situation of positive dirction, the present invention senses maximal value and the minimum value of the coordinate components (X component and Y component) in the coordinate set of current stroke track of character of user's handwriting input in real time, when the maximal value of the X component of the coordinate of the coordinate set of the current stroke track maximal value greater than the coordinate X component of the right margin in current Jiu Gong district 116, then the right margin in Jiu Gong district 116 is adjusted to the maximal value of X component of coordinate of the coordinate set of this current stroke track in real time; Perhaps, the minimum value of the coordinate X component in the coordinate set of current stroke track is less than the minimum value of the X component of the left margin coordinate in Jiu Gong district, and then the left margin in Jiu Gong district 116 is adjusted to the minimum value of X component of coordinate of the coordinate set of this current stroke track in real time.Adjustment on Y-direction is similar with it, namely when the maximal value of the Y component of the coordinate of the coordinate set of the current stroke track maximal value greater than the coordinate Y component of the coboundary in current Jiu Gong district 116, then the coboundary in Jiu Gong district 116 is adjusted to the maximal value of Y component of coordinate of the coordinate set of this current stroke track in real time; Perhaps, the minimum value of the coordinate Y component in the coordinate set of current stroke track is less than the minimum value of the Y component of the lower boundary coordinate in Jiu Gong district, and then the lower boundary in Jiu Gong district 116 is adjusted to the minimum value of Y component of coordinate of the coordinate set of this current stroke track in real time.

Fig. 6 A and Fig. 6 B have shown the example that the size in Jiu Gong district 116 is adjusted in real time.As shown in Figure 6A, when input in reduplicated word input field 114 " my god " during word, the lower-left end that the first two stroke is positioned at 116, the three strokes in current Jiu Gong district has exceeded the zone in current Jiu Gong district 116.Thus, shown in Fig. 6 B, adjust in real time so that the left margin in Jiu Gong district 116 to move to left, lower boundary moves right, and down to the minimum value of the X component of the coordinate of the coordinate set of the 3rd stroke and the minimum value of Y component, makes the 3rd stroke be positioned at Jiu Gong district 116.

When the border that it should be noted that Dang Jiugong district 116 was moved, also towards the skew of border moving direction, namely dynamic adjustment had all taken place to its geometric center in the size in Jiu Gong district 116 and position usually.At this moment, the also equal proportion adjustment according to the adjustment of boundary length of rectangle region in the Jiu Gong district 116 is so that the size and dimension of each rectangle region is identical.

In order to make the stroke cutting that better effect can be arranged, be preferably with the size in ad hoc fashion control Jiu Gong district 116 and the real-time adjustment of position, to cover the stroke of user's input accurately, guarantee that all strokes of current combination of strokes all fall in the scope in this Jiu Gong district 116.

A preferred embodiment of the invention is according to the border of adjusting Jiu Gong district 116 in real time that is worth most of the coordinate components in the coordinate set of current stroke track (X component and Y component).Preferably, when a border in Jiu Gong district to a direction move one apart from the time, if will also move the distance that equates and arbitrary stroke of current combination of strokes is fallen into outside the scope in this Jiu Gong district 116 to this direction with the right border of this borderline phase, then also moving the distance that equates to this direction with the right border of this borderline phase, otherwise, will move one to same direction with the right border of this borderline phase and can not make arbitrary stroke of current combination of strokes fall into the extraneous ultimate range in this Jiu Gong district 116.

For instance, when the maximal value of the X component of the coordinate of the coordinate set of the current stroke track maximal value greater than the coordinate X component of the right margin in current Jiu Gong district 116, then the right margin in Jiu Gong district 116 is in real time to moving the maximal value of a distance to the X component of the coordinate of the coordinate set of this current stroke track, simultaneously, if the left margin in this Jiu Gong district 116 is also moved right this distance and the stroke of current combination of strokes is exceeded outside the scope in Jiu Gong district 116, this distance that then left margin in this Jiu Gong district 116 also moved right one can not make the stroke of current combination of strokes not exceed ultimate range outside the scope in Jiu Gong district 116 otherwise left margin moved right.The specific embodiment of this adjustment mode will specify in the back.

According to another embodiment of the present invention, a border in Dang Jiugong district to a direction move one apart from the time, with right another border of this borderline phase mobile distance that equates round about.This adjustment mode can make several guarantors center (being the position) in Jiu Gong district remain unchanged.

According to a kind of preferred implementation, when the stroke track acquisition range of Touch Screen 110 in the reduplicated word input field or when overlapping with it, the zone in the Jiu Gong district 116 after the adjustment is no more than described reduplicated word input field 114, be that adjustable dimension has a scope, be limited to the size of reduplicated word input field 114 on this scope.For example, can be 0.5 * 0.5～0.9 * 0.9 (long * wide) doubly between the size of described reduplicated word input field 114.Preferred, Jiu Gong district 116 adjusted size scopes can be between the size of 0.6 * 0.6～0.8 * 0.8 reduplicated word input field 114.

As mentioned above, when user's hand-written stroke input surpassed the scope in Jiu Gong district 116, this moment, 116 meetings of Jiu Gong district be adjusted size according to the stroke that surpasses, and made in Jiu Gong district 116 scopes after the stroke that originally exceeded can fall into adjustment.But the user might exceed the scope of reduplicated word input field 114 when handwriting input, but in the above-described embodiment, the maximum magnitude in Jiu Gong district 116 should not surpass the stroke track acquisition range of Touch Screen.

Yet, according to another embodiment of the present invention, when stroke track acquisition range during greater than the reduplicated word input field, allow that the stroke of user's handwriting input can exceed the reduplicated word input field 114 of setting this moment, and the Jiu Gong district 116 after therefore allowing to adjust is above reduplicated word input field 114 scopes.Fig. 6 C and Fig. 6 D have shown the example that the size in Jiu Gong district is adjusted in real time.Shown in Fig. 6 C, when user inputs character " my god " the end position of first stroke when exceeding the coboundary in Jiu Gong district 116, at this moment, shown in Fig. 6 D, Jiu Gong district 116 can adjust upward its position, coboundary, so that exceed the scope of reduplicated word input field 114.In each above-mentioned embodiment, when character of user's handwriting input, if the stroke track coordinate surpasses current Jiu Gong district 116, then the border in Jiu Gong district 116 will be adjusted in real time according to aforesaid adjustment mode.A kind of preferred implementation is, after cutting step (step S4) is finished combination of strokes to stroke cutting was judged, Jiu Gong district 116 returned to original dimension and initial position automatically, with the judgement basis that cuts as the lasting input pen cutting-up of user.Other embodiment also can be that Jiu Gong district 116 returns to original dimension and initial position automatically after the identification of finishing a character.

As previously mentioned, the scope of reduplicated word input field 114 can be set up on their own by the user.Preferably, after the size of reduplicated word input field 114 changed, the original dimension size in Jiu Gong district 116 is the equal proportion convergent-divergent according to the setting of reduplicated word input field 114 also.

Hand input device of the present invention is described below.Fig. 7 is the module diagram of hand input device of the employing above-mentioned display method of one embodiment of the present of invention.As shown in Figure 7, this hand input device comprises: touch screen 110, touch-control module 120, memory module 130, cutting module 140, display control module 150.

Wherein said touch screen 110 produces touching signals and this touching signals is passed to touch-control module for the touch-control input of sensing user, and it also is used for the track according to the stroke of the real-time explicit user touch-control input of the display effect of display control module setting; Described touch-control module 120 is used for receiving the touching signals by Touch Screen 110 sensings, and generates the user in the stroke track of Touch Screen 110 inputs according to this touching signals, and this stroke track is a coordinate set of arranging by the touch-control sequential; Described memory module 130 is used for the coordinate set of the stroke track of real-time storage touch-control module 120 generations, and stroke starting point (starting to write a little) coordinate and stroke terminating point (lifting a point) coordinate; Described cutting module 140 is used for judging whether the stroke of current input satisfies default stroke and cut condition, and is judged as when satisfying the cutting condition indicated number control module 150 and carries out cutting operation; Described display control module 150 is used for carrying out cutting operation, and the display effect that cutting operation refers to set previous stroke is different from the display effect of current stroke.

An embodiment of real technique of writing input Chinese character when describing the display packing of utilizing continuous handwriting input of the present invention and device below with reference to Fig. 8 A～Fig. 8 H.This embodiment by have import on the intelligent handheld device of supporting continuous handwriting input display packing of the present invention Chinese character " day ", D score two words, the position in the Jiu Gong district among this embodiment and size are according to user's hand-written touch-control input and real-time adjustment.Describe the flow process of the hand-written stroke of input among this embodiment in detail below in conjunction with diagram.For convenience of description, the district of Jiu Gong described in the figure 116 all is shown in the reduplicated word input field 114 to express mode, and first rectangle region to the, nine rectangle regions are denoted as hollow " 1 "～" 9 " in regular turn.

Fig. 8 A and Fig. 8 B show user among this embodiment import Chinese character " my god " with the stroke input sequence of D score.Wherein, " my god " first to fourth stroke of word represents with T1～T4 that respectively first to the 3rd stroke of D score word is represented with X1～X3 respectively.In this embodiment, the pen district is distinguished and lifted to employing starting to write shown in Fig. 5 B, the namely default district of starting to write is first rectangle region, second rectangle region, the 3rd rectangle region and the 4th rectangle region, and default to lift that pen distinguishes be the 5th rectangle region, the 6th rectangle region, the 7th rectangle region, the 8th rectangle region and the 9th rectangle region.

Shown in 8C figure, the user touch Touch Screen reduplicated word input field 114 input " day " the first stroke T1 of word, its point coordinate of starting to write is positioned at first rectangle region, lifts the coordinate that pen puts and is positioned at the 3rd rectangle region.For highlight stroke start to write the position with lift a position, point out that with circle stroke starts to write a little in the drawings, and point out that with triangle stroke lifts a point in the diagram.In the first stroke input process, described touch screen 110 sensing user produce touching signals and touching signals are passed to touch-control module 120 in the touch-control input of input first stroke T1; The touching signals that touch-control module 120 receives by Touch Screen 110 sensings, generate the user at the first stroke track of Touch Screen 110 inputs according to this touching signals, this stroke track is a coordinate set of arranging by the touch-control sequential, and namely the user lifts the coordinate set by the arrangement of touch-control time sequencing of continuous touch-control generation the pen from starting to write to when writing a stroke.The coordinate set of the stroke track that memory module 130 real-time storage touch-control modules 120 generate, when interrupting (can be that the length that time span or track interrupt is judged according to what interrupt) when touch-control module 120 detects touching signals, judge that then the user has finished the input of a stroke.A complete stroke track has starting point and the terminating point of stroke, starting to write a little and lift some during corresponding touch-control.Memory module 130 is also stored this stroke starting point coordinate and stroke terminating point coordinate, so that cutting module 140 is used for the judgement of whether cutting.Cutting module 140 judges that at first whether the stroke of current input is user's stroke of input first in current incoming task, if Shu Ru stroke is not first then carried out cutting operation.Since input " my god " be the stroke of importing first during the first stroke T1 of word, so cutting module 140 is not operated.Whether current stroke is that the stroke of importing first can be judged according to whether storing previous stroke track in the memory module 130, also can judge according to other configuration information of input media.Display control module 150 first stroke T1 are set to first display effect, and Touch Screen 110 shows this first stroke T1 in real time with first display effect.As shown in the figure, in this embodiment, first display effect is black solid line.

Shown in Fig. 8 D, then input of user " my god " the second stroke T2 of word, starting point coordinate is positioned at the 4th rectangle region, memory module begins to store the track of the second stroke T2, cutting module 140 is judged the non-stroke of input first of current stroke, then judges whether to satisfy default stroke cutting condition thus.Because the point coordinate of starting to write of second stroke (current stroke) is positioned at the default district of starting to write, and a point coordinate of lifting of first stroke (previous stroke) is not positioned at a default district of lifting, therefore cutting module judges that current stroke does not meet default stroke cutting condition, this moment cutting module 140 not to " day " second stroke of character cuts with previous stroke (first stroke), the general " my god " first stroke and second stroke of character be divided into current combination of strokes; Display control module 150 does not change the current display effect of each stroke, and namely Touch Screen 110 all shows the track of first stroke and second stroke with first display effect.

Shown in Fig. 8 E, finish input " my god " second stroke of word, and the terminating point of second stroke (lifting a point) coordinate is positioned at the 6th rectangle region.Begin subsequently input " my god " the 3rd stroke of word, and the starting point of the 3rd stroke (starting to write a little) coordinate is positioned at second rectangle region, at this moment, cutting module 140 judges that the point coordinate position of starting to write of the 3rd stroke (current stroke) is positioned at the default district of starting to write, and the coordinate position of the terminating point (lifting a point) of second stroke (previous stroke) is positioned at the default pen of lifting and distinguishes, therefore cutting module 140 is judged as and satisfies default stroke cutting condition, will " my god " the 3rd stroke and second stroke of character cut, will " my god " first stroke and second stroke of character change into previous combination of strokes by current combination of strokes, " my god " the 3rd stroke of character then is divided into current combination of strokes, just make " my god " the 3rd stroke and first of character, second stroke is cut into different combination of strokes.Afterwards, display control module 150 to " my god " the previous combination of strokes of character and current combination of strokes carry out difference and draw and show and handle, make " day " Show Color of the stroke of the first stroke of character and the previous combination of strokes of second stroke light (second display effect that becomes, for example be the solid line of grey), and " my god " the 3rd stroke Show Color of character is for being the real black line of first display effect still.

Shown in Fig. 8 F, finish input " my god " the 3rd stroke T3 and four-stroke T4 of character, in the process of input, because the point coordinate position of starting to write that a point coordinate position is positioned at the 7th rectangle region and four-stroke of lifting of the 3rd stroke is positioned at the 5th rectangle region, therefore do not meet default stroke cutting condition, cutting module 150 not to " my god " the 3rd stroke and the four-stroke of character cut, just will " my god " the 3rd stroke and the four-stroke of character be divided into identical combination of strokes (current combination of strokes).

According to one embodiment of the present invention, memory module 130 can be divided at least one memory block 131, the track data of each stroke that the user produces in the handwriting input process (trajectory coordinates set, start to write point coordinate and lift a point coordinate) all be stored in the memory block 131.And memory module is that a pointer 132, the order of the stroke of storing in the value representation memory block of this pointer 132 are distributed in each memory block 131.When not beginning to import stroke, pointer value is zero.When new stroke of the every input of user, just produce a new buffer area 131 in the memory module 130 and store the track data of this stroke, and the order of input stroke is that a pointer is distributed in this memory block according to being somebody's turn to do newly.

For example, as shown in Figure 9, first buffer area (1311) storage is the track data of the first stroke of input continuously, its pointer value is the track data of 1, second buffer area (1312) storage, second stroke, its pointer value is 2,, the track data of N buffer area (131n) storage N stroke, its pointer value is n.After the user stops handwriting input, (after for example stopping to import 3 seconds), pointer value makes zero, and waits for user's continuous input of next time.

According to the present invention, described memory module 130 is also stored cleavage, separation indication between the stroke that cleavage is represented to arrange in order, it is not physically a position, such as between the 3rd stroke T3 and previous stroke T2, satisfying default cutting condition, then cleavage is represented to separate between the 3rd stroke T3 and previous combination of strokes T1, the T2, for example shown in Fig. 8 A and the 8B, when the user import continuously " my god " with D score two words, " my god " word first stroke to the four-stroke is represented by T1～T4, and D score word first stroke to the three strokes are represented by X1～X3.Memory module 130 is imported order of strokes according to the user and stroke T1, T2, T3, T4, X1, X2 and X3 is stored in the memory block 1311～1317 of memory module 130 in regular turn, and has distributed pointer according to order of strokes for each memory block.

As shown in Figure 9, the pointer value of the memory block 1311 of storage stroke T1 is 1, the pointer value of the memory block 1312 of storage stroke T2 is 2, the pointer value of the memory block 1313 of storage stroke T3 is 3, the pointer value of the memory block 1314 of storage stroke T4 is 4, the pointer value of the memory block 1315 of storage stroke X1 is 5, and the pointer value of the memory block 1316 of storage stroke X2 is 6, and the pointer value of the memory block 1317 of storage stroke X3 is 7.In order to explain orally conveniently, can represent cleavage between the stroke and storage in memory module 130 with the data that are associated with the pointer value of memory block.For example, represent the cleavage that the 3rd stroke T3 and previous stroke T1, T2 separate with " I2 ", by the storage cleavage, make method and apparatus of the present invention can support display control module 150 according to cleavage stroke formerly to be set different display effects, for example the light and shade classification display hereinafter will specifically be illustrated.

According to one embodiment of the present invention, display control module 150 will be set the 3rd display effect with cleavage before the combination of strokes nearest apart from current cleavage, and be set at second display effect with current cleavage and apart from the combination of strokes between the nearest cleavage of current cleavage.At this, current cleavage refers to the cleavage that its generation time and current time approach the most.For example, in the above embodiments, if current stroke is the 3rd stroke or four-stroke, so current cleavage refers to the cleavage between second stroke and the 3rd stroke, i.e. aforesaid cleavage " I2 ".

Preferably, the 3rd display effect is Transparent color, does not namely show the track of stroke.Can avoid stroke to be shown in too much on the Touch Screen 110 like this.Continue to use top example below and come this preferred implementation is described with reference to Fig. 8 G and Fig. 8 H.

Shown in Fig. 8 G, the user continues the first stroke X1 of input D score character in reduplicated word input field 114.And the starting point of the first stroke X1 of D score character (starting to write a little) coordinate is positioned at first rectangle region, and " my god " terminating point (the lifting a point) coordinate position of the four-stroke T4 of character is positioned at the 9th rectangle region.Owing to meet default stroke cutting condition, therefore cutting module 150 will " my god " the four-stroke T4 of character cuts into different combination of strokes with the first stroke X1 of D score character, generate a new cleavage, and as current cleavage, namely, " my god " combination of strokes of the four-stroke of character changes into previous combination of strokes by current combination of strokes, the first stroke of D score character then is current combination of strokes, " my god " second stroke of character and the cleavage between the 3rd stroke become previous cleavage, and the most approaching with current cleavage.

Thus, display control module 140 to " my god " first to fourth stroke of character shows with the display effect of the first stroke (current stroke) that is different from the D score character.In this embodiment, make " my god " first stroke of character and second stroke are with the 3rd display effect, namely Transparent color shows (not showing), make " my god " the 3rd stroke of character and four-stroke are with second display effect, namely grey solid line shows.And the first stroke of D score character still shows (black solid line) with the first default display effect.

Shown in Fig. 8 H, the user finishes the first stroke of input D score character, and continue to finish the second stroke X2 of D score character and the input of three-character doctrine X3, because in the second stroke X2 of input D score character and the process of the 3rd stroke X3, default stroke cutting condition does not appear meeting, cutting module 150 does not cut stroke, so the first stroke of D score character, second stroke and the 3rd stroke belong to identical combination of strokes, i.e. current combination of strokes.Display control module does not change the display effect of previous stroke, and just the first stroke of D score character, second stroke and the 3rd stroke all have the equal black solid line and show.

It is two independently processes that the character recognition that it should be noted that stroke of the present invention cutting and handwriting input is preferably.Make hand input device of the present invention possess the function of identification character, then it can comprise a character recognition module (not shown among Fig. 7), this character recognition module can adopt existing module to come framework, and the stroke of storing in the read storage device is carried out character recognition, and the identify character or the character alternate item that obtain are shown at Touch Screen.Display packing of the present invention can be associated with character recognition, can be not related yet, do not carry out association but be preferably.

That is to say that the operation that the present invention is preferably the operation of character recognition module and cutting module of the present invention 140, display control module 150 is to carry out independently respectively.Therefore in this embodiment, " day " stroke of word and the stroke of D score word be not have differentiation for cutting module 140.

But the present invention is not limited to this, and cutting module 140 of the present invention can will belong to the stroke of the character of difference according to the recognition result that module known in character forces cutting.That is to say that default stroke is separated condition also can comprise the judgement that whether belongs to same character for current stroke and previous stroke.

In addition, cutting module 140 of the present invention also can arrange cleavage according to the number of the stroke of input after current cleavage.That is force cutting when, the number of the stroke of input reaches a threshold value after current cleavage.The too much problem of stroke that shows in the time of can preventing from like this importing complicated character.

According to the present invention, above-mentioned stroke cutting condition can be used separately, also can be used in combination mutually, all in protection scope of the present invention.

In addition, described in the above embodiment of the present invention for the three grade display effects of the stroke between each cleavage according to " black solid line-grey solid line-Transparent color ".But the present invention can adopt the multistage demonstration of the various users of being beneficial to from visually distinguishing." black solid line-grey solid line-dotted line edge-Transparent color " level Four for example shown in Figure 10 shows, when importing the first stroke of " being " word more afterwards in " all over the world ", " my god " first, second stroke of word becomes Transparent color, three, four-stroke has shown the dotted line edge, first to the 3rd stroke of D score word is shown as grey solid line, " being " word first and draw and to have shown black solid line.

Or, also can adopt other classification display effect, show such as " black-mazarine-light blue-Transparent color " level Four.The setting of classification display effect all is to change, to increase and to obtain in the embodiment that the present invention provides to those skilled in the art like this, so it all belongs within protection scope of the present invention.

Understand the present invention program in the aforesaid diagram for convenience, the edge of reduplicated word input area is identified, to the district of starting to write, lift the pen district and nine palace lattice with dashed lines are labelled, and will start to write a little and lift a point coordinate and identify with circle and triangle.But in the hand input device in reality, optionally show or do not show above-mentioned sign.Among the embodiment as shown in figure 11, also comprise the zone of the alternate item of the zone that shows input character and character recognition on the Touch Screen.And do not show any above-mentioned accessory ID in the reduplicated word input field.

Figure 12 A to Figure 12 G has shown another embodiment of the present invention, has wherein shown the real-time adjustment in Jiu Gong district when progressively importing Chinese character.This embodiment has shown wherein a part of process of user's handwriting input Chinese character " merit ".Shown in Figure 12 A, the first stroke of " merit " word, second stroke and the 3rd stroke are judged as and belong to same combination of strokes.Four-stroke when user's handwriting input Chinese character " merit ", the top of the coboundary that the starting to write of four-stroke a little is positioned at current Jiu Gong district, at this moment, step S3, cutting module 140 can't be distinguished and lift the pen district according to starting to write of current Jiu Gong district and judge whether stroke cutting condition is satisfied, therefore, need adjust in real time position and the size of nine palace lattice.In this embodiment, in step S3, at first the difference of the coordinate Y component of the coordinate Y component of the stroke track of 140 pairs of four-strokes of cutting module and coboundary is calculated in real time, the coboundary that needing to obtain the Jiang Jiugong district is displacement y1 at least upwards, and starting to write of four-stroke a little is included in the Jiu Gong district 116.Simultaneously, the lower boundary in cutting module 140 calculating Jiu Gong districts and current combination of strokes be not (owing to carry out the stroke cutting as yet, therefore refer to first stroke, second stroke and the 3rd stroke) bee-line be y2, be the maximum permissible distances that lower boundary moves up, and can be by relatively obtaining y2 greater than y1.Thus, the lower boundary in cutting module 140 Jiang Jiugong districts 116 distance y 1 that also moves up is shown in Figure 12 B.

Then, judge whether to satisfy stroke cutting condition according to the Jiu Gong district after adjusting.This embodiment adopts the setting of lifting pen district and the district of starting to write shown in Fig. 5 A.As can be known, the pen point lifted of the 3rd stroke is positioned at and lifts the pen district and starting to write of four-stroke a little started to write district, so cutting module 140 is judged as and satisfies stroke and cut condition, four-stroke and the 3rd stroke is cut also classification display, shown in Figure 12 C.

Shown the situation of finishing the handwriting input four-stroke among Figure 12 D.Owing to carried out the stroke cutting, therefore, current combination of strokes includes only four-stroke, only needs to adjust the Jiu Gong district according to the value of the trajectory coordinates set of four-stroke self.With reference to Figure 12 D and Figure 12 C, by real-time adjustment, the Jiu Gong district 116 among Figure 12 D makes progress again and the distance that moved right with respect to Figure 12 C simultaneously, and detailed process and preceding similar does not repeat them here.

Shown in Figure 12 E, when finishing four-stroke and beginning the 5th stroke of handwriting input " merit " word, and the top of the coboundary that the starting to write of the 5th stroke a little is positioned at current Jiu Gong district again, at this moment, step S3 can't distinguish and lift the pen district according to starting to write of current Jiu Gong district again and judge whether stroke cutting condition is satisfied, therefore, need adjust in real time position and the size of nine palace lattice.With preceding similar, in step S3, at first 140 pairs of the 5th strokes of cutting module start to write a little coordinate Y component and the difference of the coordinate Y component of coboundary calculate in real time, the coboundary that needing to obtain the Jiang Jiugong district is displacement y1 ' at least upwards, and starting to write of four-stroke a little is included in the Jiu Gong district 116.Simultaneously, the lower boundary in cutting module 140 calculating Jiu Gong districts and current combination of strokes be not (owing to carry out the stroke cutting as yet, therefore still refer to four-stroke) bee-line be y2 ', be the maximum permissible distances that lower boundary moves up, and can be by relatively obtaining y1 ' greater than y2 '.Thus, the lower boundary in cutting module 140 Jiang Jiugong districts 116 distance y 2 ' that moves up makes nine palaces can cover the lower end of four-stroke just, shown in Figure 12 F.Among this embodiment, for the size that guarantees each district in the Jiu Gong district is identical with shape, need carries out equal proportion to the cut-off rule in each district and put in order.
