Specific embodiment
The present invention is described in further detail with reference to the accompanying drawings and examples.It is understood that this place is retouched
The specific embodiment stated is used to explain the present invention, rather than limitation of the invention.It also should be noted that for the ease of retouching
It states, only the parts related to the present invention are shown in attached drawing rather than entire infrastructure.
Embodiment one
Fig. 1 is a kind of flow chart of the method for handwriting trace adjustment that the embodiment of the present invention one provides.It is provided in embodiment
Handwriting trace adjustment method can by handwriting trace adjust equipment execute, the handwriting trace adjustment equipment can pass through
The mode of software and/or hardware realizes that the equipment of handwriting trace adjustment can be two or more physical entities and constitute, can also
To be that a physical entity is constituted.For example, the equipment of handwriting trace adjustment can be mobile phone, industrial control computer etc..
In order to make it easy to understand, using intelligent interaction plate as actual vector in embodiment, the adjustment of exemplary description handwriting trace
Method implement when adjustment target choose, be associated with and adjust respond detailed process.Wherein, intelligent interaction plate, which can be, passes through
Touch technology is manipulated and is realized the integration apparatus of man-machine interactive operation to the content being shown on display plate, is integrated
The one or more functions such as projector, electronic whiteboard, curtain, sound equipment, television set and video conference terminal.
In general, intelligent interaction plate includes at least one piece of display screen.For example, intelligent interaction flat panel configurations have one piece of tool
There is the display screen of touch function, and the display screen can be capacitance plate, touch screens or electromagnetic screen.In the present embodiment, it provides
A kind of intelligent interaction plate, further, user can realize touch-control by way of finger or stylus touching display screen
Operation correspondingly, intelligent interaction plate 1 detects position of touch, and is responded according to position of touch, to realize touch function.
Typically, intelligent interaction plate is equipped at least one operating system, wherein operating system includes but is not limited to Android system
System, linux system and Windows system.Further, intelligent interaction plate can install at least one with writing function
Application program.Wherein, the application program which can carry for operating system, meanwhile, it is also equipped with from third party and sets
The application program downloaded in standby or server.Optionally, application program also has other editor's function in addition to having writing function
Can, such as insertion table, insert pictures, illustration figure, drafting table, graphing function.Wherein, the table drawn or
Figure is computer drawing leading element.The printing that computer drawing leading element is understood that be drawn by intelligent interaction plate
Body leading element is different from the element of user's writing.
Specifically, the method for handwriting trace adjustment specifically includes with reference to Fig. 1:
Step S101, the first touch control operation for acting at least one handwriting trace is received.
On the touch screen of the intelligent handwritings device configurations such as electronic whiteboard, electronic blackboard, Digitizing plate, intelligent meeting plate,
The writing operation for responding user is provided with to show the writing region of input content, when the writing region is write,
Touch screen is such as contacted by stylus or finger, touch screen can sense the variation of infrared ray, the variation of electric current, the change of voltage
Change or the variation of magnetic flux is (corresponding to infrared type touch screen, capacitive touch screen, resistive touch screen or electromagnetical type touch screen
Specific setting type), the touch signal of the coordinate containing touch location and the triggered time of the touch signal are obtained, according to touching
It touches the coordinate of position and the triggered time of touch signal, available stylus or user's finger press writing to lifting every time
Stop the track data of handwriting trace inputted in writing process, according to track data touch screen writing region real-time display
The handwriting trace of user's input.Certainly, writing process is not limited to write, in any use that the touch screen of intelligent handwriting equipment is realized
Input Process in display operation track can be considered writing process.Behaviour of the implementation of this programme i.e. for existing handwriting trace
Make.
On the touchscreen, to the response of touch control operation, generally there are three types of as a result, the first is will to correspond to as mentioned before
The track data response of touch control operation is handwriting trace, this is one is most common and relatively simplest, usually,
The mobile input for being all considered as handwriting trace of the routine of single touch point；Second is a of touch point when touch control operation occurs
Number, time and/or track characteristic are compared, if matched with some setting operation prestored, trigger the setting operation pair
Some function of answering, such as popup menu, choose target etc.；The third is complicated non routine operation, such as the touching of ten finger of both hands
Random motion when control, the input that this mode may can neither be handled as handwriting trace are also matched less than the setting behaviour prestored
Make, then this touch control operation is not responded.In the present solution, if the touch control operation of user belongs to second, and with it is pre-
The setting operation matching for the hit handwriting trace deposited, then confirmation detects the triggering of the handwriting trace to touch control operation hit.
Such as in Fig. 3, via multiple handwriting traces form " creativeness " three words, finger therein if it is
The display interface of " creativeness " is free to slide, then new handwriting trace can be formed in display interface；If finger therein be
The reception of the first touch control operation is completed in position shown in Fig. 3, then confirms that " 亅 " that finger is directed toward is confirmed as the effect of the first touch control operation
Handwriting trace.Here, " creativeness " is mainly human eye Text region as a result, in actual bottom layer treatment, each is write
Track can simply be recorded as the coordinate data of multiple pixels, and intelligent interaction plate itself is only according to coordinate data in display page
Iso-surface patch goes out multiple handwriting traces, without identify these handwriting traces combination after essentiality content.It is being based on pixel
When carrying out the rendering of handwriting trace, pixel is drawn according to the coordinate data of preservation, based on smooth curves such as Beziers
Drafting scheme draws on the basis of the pixel drawn and obtains the complete handwriting trace that eye recognition arrives, and is based on the drafting
Mode can effectively reduce the memory space requirements of handwriting trace, improve the rendering speed of handwriting trace.
It should be noted that handwriting trace shown in Fig. 3 is examined for example, by intelligent interaction plate 1 shown in Fig. 2
It surveys and shows, in the present embodiment and subsequent embodiment, put down for purposes of illustration only, handwriting trace is not additional to intelligent interaction
It is shown in plate 1, but illustrates the implementation process of this programme by the opposite variation between handwriting trace.
Step S102, in response to first touch control operation, the handwriting trace group including at least two handwriting traces is determined,
At least two handwriting traces include the selected handwriting trace of first touch control operation, and are existed mutually at least one default
Logic association relationship.
For group interaction scene, when user has the demand for carrying out batch processing, usually handwriting trace is orderly
Combination, the standard of this sequential combination are described herein as logic association relationship, and according to different dimensions, logic association relationship can be with
For space inclusion relation, position grouping relationship, spatial and temporal association etc..Such as when needing to be emphasized writing emphasis, in book
It writes and has drawn a closed figure outside emphasis, there are space inclusion relations for handwriting trace of the closed figure to its inside；Such as it needs
When carrying out continuing handwriting input based on some preset shape (table etc.), the handwriting trace of the preset shape is formed and with this
Based on the handwriting trace that persistently inputs there are position grouping relationships；Such as when one width figure of one section of continuous writing words or drafting, base
The relationship that the time relationship of two neighboring handwriting trace and distance relation are established in writing or drawing process, referred to as space time correlation
Relationship, in the handwriting trace that " creativeness " is formed in Fig. 3, any two time is gone up between adjacent handwriting trace, time relationship
All very close with distance relation, there are spatial and temporal associations between " creativeness " corresponding handwriting trace.
When carrying out the initial treatment of track data, the writing rail of spatial and temporal association will be present to handwriting trace
Mark, which is associated, to be saved in the same container, and container can specifically be safeguarded by array, set or dictionary.If using
Array or set safeguard, every group of associated handwriting trace can be protected by passing through an array or set respectively
Deposit, that is to say, that if there are the associated handwriting trace of multiple groups in current display page, need to safeguard same number array or
Set, i.e., a page needs to safeguard multiple arrays or set.If, can each display page maintenance by the way of dictionary
One dictionary, one group of associated handwriting trace can be saved in one page in dictionary in a display page.In the present solution, right
The association maintenance strategy of handwriting trace that should be discrete in the display page, using dictionary as the data knot for realizing this maintenance
Structure, can be effectively reduced the complexity of writing track data maintenance, and the realization of bottom data treatment process is simpler.
The whole handwriting traces for including in a container are shown in Fig. 3, the boundary rectangle 11 of handwriting trace in the container
As shown in the figure, it should be noted that the boundary rectangle 11 in Fig. 3 is only the aobvious of the handwriting trace for illustrating to safeguard in a container
Demonstration is enclosed, and boundary rectangle 11 is not shown in display screen under writing state.
Different types of handwriting trace can use different maintenance modes, for composition closed figure and some default shape
Shape can be integrated into a handwriting trace and is individually present.For closed figure (such as circle, rectangle, square etc.) and
Preset shape (five-pointed star), the preservation of handwriting trace is not only the isolated preservation based on a plurality of handwriting trace, but it is made
Figure for an entirety is saved, and has the whole figure of special shape feature, can be based on a few pixels point, reference point
And/or the modes such as graphic parameter are saved and are drawn, such as round preservation, will not save multiple pixels on circular arc
Coordinate data, but save the coordinate data and radius in the center of circle.
After the handwriting trace confirmation of first touch control operation effect, further confirm that its all existing logic association closes
System, if the handwriting trace is common track text input or drawn, logic association relationship there is normally only when
Null Context relationship；If target trajectory is that closed figure or setting shape, logic association relationship may relate to one
Or the handwriting trace in multiple containers, in this case, a handwriting trace group includes the writing rail that at least one is integrally saved
Handwriting trace in mark and multiple associated containers.
After handwriting trace group acknowledge, the current response for showing picture pause touch-control input, and in handwriting trace group
Handwriting trace can be highlighted with respect to the handwriting trace except handwriting trace group, after handwriting trace group acknowledge, from touch
Shield handwriting trace of the touch control operation preferential answering detected in handwriting trace group, to realize the batch tune to handwriting trace
It is whole.
Step S103, the second touch control operation is received.
It is final true if the handwriting trace of the first touch control operation hit is the track of common text input or picture
The handwriting trace in handwriting trace group recognized is the handwriting trace (there is no spatial and temporal association) or handwriting trace place
Container in all handwriting traces.If the handwriting trace of the first touch control operation hit is closed figure, final to confirm
Handwriting trace group in handwriting trace be the closed figure, and there are in the container of intersection with the closed close range
Handwriting trace.If the handwriting trace of the first touch control operation hit is to set shape, in the handwriting trace group finally confirmed
Handwriting trace be the setting shape, and there are the handwriting traces in the container of position grouping with the setting shape.
Step S104, in response to second touch control operation, the display of the handwriting trace group is adjusted.
More commonly used adjustment in batches gesture for example singly refers to drag gesture, two fingers translation gesture, refers to more and scales gesture and double
Refer to rotation gesture etc., in intelligent interaction plate to the gesture operation for determining target have realization more, and this will not be repeated here.Specific
When being adjusted, the mode that can adjust operating area there are two types of setting is adjusted the detection of gesture.One is show currently
Show that any position at interface carries out gestures detection, the content specifically adjusted is confirmed according to the gesture detected, synchronization will be adjusted specifically
Whole content (moving distance, direction, scaling, rotation angle etc.) feedback is completed to criticize to the handwriting trace in handwriting trace group
Amount adjustment.Another kind is that the region of the handwriting trace covering in handwriting trace group carries out gestures detection, the formation pair from display
Target handwriting trace and the effect for being associated with handwriting trace and directly being operated.In two ways, the corresponding specific adjustment of gestures detection
The bottom affirmation mechanism and handwriting trace of parameter are identical in response to the change mechanism of the display effect of adjusting parameter.
State shown in Fig. 4 is the state in Fig. 3 according to the state for receiving the first touch control operation in step S101, is based on
Handwriting trace in the handwriting trace group of first touch control operation confirmation highlights in Fig. 4, and highlighted region is to write
The boundary rectangle 11 of all handwriting traces in trajectory set, specifically can be and increases handwriting trace projection, and phase is arranged for handwriting trace
For the suspension display effect etc. in other regions, the boundary rectangle in Fig. 4 is only used for illustrating highlighted range, without indicating
Highlighted mode.It is corresponding, it can be using the region where the boundary rectangle as adjustment operating area, in this region detection
Second touch control operation simultaneously controls related handwriting trace and synchronizes adjustment.
It is above-mentioned, the first touch control operation of at least one handwriting trace is acted on by receiving；In response to first touch-control
Operation, determines the handwriting trace group including at least two handwriting traces, and at least two handwriting traces include first touching
The selected handwriting trace of control operation, and there is at least one preset logic association relationship mutually；Receive the second touch control operation；It rings
Second touch control operation described in Ying Yu adjusts the display of the handwriting trace group.Rail is write by touch control operation selection at least one
Mark, and then there are multiple handwriting traces of at least one preset logic association relationship to determine book according to the handwriting trace with selection
Trajectory set is write, the handwriting trace sync response in handwriting trace group operates the adjustment of handwriting trace.It, can during the adjustment
To realize that a plurality of handwriting trace is accurately chosen in once-through operation from all handwriting traces, the process chosen in batches is easy to operate,
Accuracy of selection is high.Meanwhile the adjustment operation of the boundary rectangle based on handwriting trace group and operation is exited convenient for after after choosing
Continuous operation, adjusting and exiting convenient can realize.
Embodiment two
Fig. 5 is a kind of flow chart of the method for handwriting trace adjustment provided by Embodiment 2 of the present invention.The present embodiment be
It is embodied on the basis of above-described embodiment.
Specifically, the method for handwriting trace adjustment provided in this embodiment specifically includes with reference to Fig. 5:
Step S201, the first touch control operation for acting at least one handwriting trace is received.
In the implementation of this programme, the touch point detected in the first touch control operation not will lead to display picture and become
To change, but the adjustment in batches process of handwriting trace can be triggered, the first touch control operation includes at least one touch point, and described at least one
The touch-control duration of a touch point meets the first setting, and at least one described touch point and at least one handwriting trace away from
From in the first setting range.Do not limit the number of the touch point of needs herein, it specifically can be according to the side of other interaction designs
Case is selected, and mode of operation conflict or the close bring height of mode of operation is avoided to miss touching rate.For single touch point,
Because finger contact angle, finger contact the influence of the factors such as the nib size of dynamics or smart pen, contact position may not
It can be described by the coordinate data of a coordinate points, coverage area may need multiple coordinate points that could describe, corresponding
The position of single touch point may be by a zonule of multiple coordinate points corresponding coordinate data constraint.
In the exemplary illustration of the present embodiment, the confirmation of the first touch operation is mainly by based on the touch control operation singly referred to
It is described.
Step S202, in response to first touch control operation, the handwriting trace group including at least two handwriting traces is determined,
At least two handwriting traces include the selected handwriting trace of first touch control operation, and are existed mutually at least one default
Logic association relationship.
The display position of handwriting trace is described by coordinate data, and the active position of the first touch operation is also by seat
Mark data be described, if the coordinate data (coordinate datas of at least one coordinate points) of the first touch operation just with one
The coordinate data of handwriting trace is overlapped or partially overlaps, i.e. the display of the position of the first touch control operation and at least one handwriting trace
There is intersection in position, then confirms that first touch control operation acts on the handwriting trace.If in the sphere of action of the first touch control operation
Inside there is the handwriting trace of multiple stacking inputs, is then judged as that lower layer's handwriting trace (handwriting trace usually formerly inputted) is upper
Layer handwriting trace isolation, is not applied to by the first touch control operation, and based on this judgement, the handwriting trace that top set is shown is (last defeated
The handwriting trace entered) it is confirmed as the handwriting trace of the first touch control operation effect.
If first touch control operation itself without directly hit handwriting trace, i.e., the coordinate data of the first touch control operation not with
The coordinate data of any handwriting trace has intersection, then confirmation in the pre-set radius of the first touch control operation handwriting trace go out
Existing situation；If fixed tentatively there are handwriting trace in pre-set radius as alternative handwriting trace, then from alternative handwriting trace
The handwriting trace (handwriting trace recently entered) that confirmation is shown in top layer is target handwriting trace.Certainly, it is write from alternative
The affirmation mechanism based on distance can also be used in track, that is, confirms that with a distance from the first touch control operation, nearest handwriting trace is the
The handwriting trace of one touch control operation effect.
Do not have during specific embodiment about the judgement in pre-set radius and the judgement about distance (or top set level)
There is specific context, only determines the constraint there are two condition.For example, the distance between first touch control operation can be confirmed
Then nearest handwriting trace judges the handwriting trace whether in pre-set radius, be to be confirmed as the effect of the first touch control operation
Handwriting trace；It can also first confirm the handwriting trace in pre-set radius, then confirm wherein apart from a nearest writing rail
Mark is the handwriting trace of the first touch control operation effect.
The relative positional relationship of touch control operation and handwriting trace, in addition to both the above, there are also handwriting traces to grasp in touch-control
Situation outside the pre-set radius of work, i.e. touch control operation do not have handwriting trace as effective target, at this time can be by the touch control operation
Being considered as maloperation or the touch control operation has other interaction definition, can execute corresponding interaction response.
After the handwriting trace confirmation of the first touch control operation effect, i.e., the book is inquired from corresponding data store organisation
The logic association relationship for writing track, the logic association relationship between handwriting trace and handwriting trace pass through array, set or word
Allusion quotation is safeguarded, after confirming the corresponding handwriting trace of the first touch control operation, its relationship is inquired from the handwriting trace of storage
Same book is added together with the handwriting trace that the first touch control operation acts in state, the handwriting trace that logic association relationship then will be present
Write trajectory set.Handwriting trace in same handwriting trace group integrally highlights, in addition to highlighting to handwriting trace itself,
The region that handwriting trace covers can also be highlighted, a kind of simple mode, by the corresponding external square of handwriting trace
Shape and the region entirety of encirclement highlight.
Step S203, the second touch control operation is received.
The touch point of second touch control operation receives in the boundary rectangle of the handwriting trace group.The boundary rectangle
It is covered with transparent mask.Transparent mask can be the floating layer that can detecte touch control operation, only examine in the region of its covering
The certain gestures measured can just trigger the operation of certain gestures agreement, and the region of transparent mask covering is to adjust operating space
Domain, transparent mask are to adjust the vision presentation of operating area.Transparent mask described in this embodiment is a kind of citing restriction, real
On border, the transparency of mask can be preset or be modified, with can user complete handwriting trace batch selection after, it is right
The subsequent adjustment operation of user carries out nature guidance and is preferred, and all operationss could be executed by avoiding the need for access service manual.For
The operation of batch handwriting trace, the interaction that operation is adjusted within the scope of its boundary rectangle have had enough operating spaces,
It is also avoided that the excessive bring vision interference in operating space simultaneously.
Certainly, during specific implementation, adjustment control can also be added on four sides of transparent mask and/or quadrangle, with
The coverage area of transparent mask is adjusted, minimum value and maximum value can be constrained in the adjustment of coverage area, and minimum value is for example initial
Boundary rectangle, maximum value for example amplify certain proportion or threshold pixels.During the adjustment of transparent mask, only change adjustment behaviour
Make the range in region, does not change the handwriting trace initially chosen.The adjustment process is the description based on transparent mask, is not indicated only
It is adjusted in transparent mask.
Second touch control operation includes singly referring to drag gesture, two fingers translation gesture, referring to scaling gesture and two fingers rotation more
The specific gesture-type of gesture, the second touch control operation passes through the side such as the number of touch point, mass motion direction, direction of relative movement
Formula confirmation.
Step S204, in response to second touch control operation, the display of the handwriting trace group is adjusted.
During handwriting trace in handwriting trace group is adjusted, the operation such as movement, dragging, scaling, rotation
The variation that the display parameters such as display position, display size, angles of display can be brought, is adapted to the above variation, and transparent mask is shown
Show that position, display size etc. have corresponding variation, wherein angles of display can be there are two types of accommodation mode, and one is in response to rotation
Same angle change is done in operation, another kind be adaptable to handwriting trace it is postrotational it is most upper, most under, most left and most right four points
Coordinate, regenerate boundary rectangle, the four edges of boundary rectangle are still parallel with a reference axis in coordinate system, and another
One reference axis is vertical, corresponding, and the enclosing region of boundary rectangle is the overlay area of transparent mask.
Step S205, third touch control operation is received outside the boundary rectangle.
Number of the third touch control operation for touch point, operation duration, motion profile feature etc. is without especially clear
Requirement operated in actual operation to the region except handwriting trace group, be considered as and abandoned to handwriting trace group
Adjustment.
Step S206, in response to the third touch control operation, it is switched to write mode.
Operating gesture is detected except operating area adjusting, then illustrates the adjustment in batches of the operating gesture and handwriting trace
