The writing operation method of the smart interaction tablet provided in the embodiment may be executed by an operation device of the smart interaction tablet, the operation device of the smart interaction tablet may be implemented in a software and/or hardware manner, and the operation device of the smart interaction tablet may be formed by two or more physical entities or may be formed by one physical entity. For example, the operating device of the smart interactive tablet may be a cell phone, an industrial control computer, or the like.

For the convenience of understanding, in the embodiment, the intelligent interactive tablet is taken as an actual carrier, and a detailed process of adjusting target selection, association and adjusting response when the writing operation method of the intelligent interactive tablet is implemented is exemplarily described. The intelligent interactive panel can be an integrated device which controls the content displayed on the display panel and realizes man-machine interactive operation through a touch technology, and can integrate one or more functions of a projector, an electronic whiteboard, a curtain, a sound box, a television, a video conference terminal and the like.

Generally, as shown in fig. 2, the smart interactive tablet 1 includes at least one display screen. For example, the smart interactive tablet 1 is configured with a display screen with touch function, and the display screen may be a capacitive screen, a resistive screen or an electromagnetic screen. In this embodiment, an intelligent interactive tablet is provided, and further, a user may implement a touch operation by touching a display screen with a finger or a stylus, and accordingly, the intelligent interactive tablet detects a touch position and responds according to the touch position to implement a touch function. Typically, the smart interactive tablet is installed with at least one operating system, wherein the operating system includes, but is not limited to, an android system, a Linux system, and a Windows system. Further, the smart interactive tablet may install at least one application having a writing function. The application program may be an application program carried by an operating system, and an application program downloaded from a third-party device or a server is also installed. Optionally, the application program has other editing functions besides the writing function, such as inserting tables, inserting pictures, inserting graphics, drawing tables, drawing graphics, and the like. And the drawn table or graph is a standard element drawn by the computer. Computer drawn standard elements may be understood as print standard elements drawn by an intelligent interactive tablet, which are distinguished from elements written by a user.

A touch screen configured by intelligent handwriting equipment such as an electronic whiteboard, an electronic blackboard, a digitizer, an intelligent conference tablet and the like is provided with a writing area for responding to the writing operation of a user to display input content, when writing is performed in the writing area, for example, a touch pen or a finger is used to touch the touch screen, the touch screen can sense the change of current, the change of voltage or the change of magnetic flux (corresponding to the specific setting type of the capacitive touch screen, the resistive touch screen or the electromagnetic touch screen), so as to obtain a touch signal containing the coordinates of the touch position and the trigger time of the touch signal, according to the coordinates of the touch position and the trigger time of the touch signal, track data of the handwriting input during the process of writing the touch pen or the finger of the user to lift the touch pen or the finger of the user can be obtained, and the handwriting input by the user is displayed in the writing area of the touch screen in real time according to the track data. Of course, the writing process is not limited to writing, and any entry process implemented on the touch screen of the intelligent handwriting device for displaying the operation track can be regarded as the writing process. In addition, the touch operation may respond to operations such as clicking, dragging, and the like of the user according to the difference of the display element of the occurrence position of the touch operation. The way in which these different responses are processed at the bottom level is the same. Generally, the area where the touch writing occurs coincides with the area where the display is located, i.e., the display area 2 shown in fig. 2. Based on the hardware realization of basic functions such as touch and display, the function of whiteboard application can be further realized on the intelligent interactive flat plate, and each embodiment of the scheme is the scheme realization of the whiteboard application.

Specifically, referring to fig. 1, the writing operation method of the intelligent interactive tablet specifically includes:

and S101, receiving handwriting windowing operation generated on a whiteboard application interface.

The application interface refers to an interactive interface used for receiving and/or displaying information, such as an application of a video playing class, and the interactive interface is mainly used for displaying a changed video picture; the real-time communication type application, wherein the interactive interface is mainly used for receiving the content input by a near-end user and displaying the content input by a far-end user; the interactive interface of the file editing application is mainly used for receiving and displaying the content input by the user; the interactive interface of the browser-type application is mainly used for receiving keywords input by a user and displaying webpage content obtained based on the keywords.

In this embodiment, the application interface specifically targeted refers to a user interface presented in the whiteboard application use process, that is, a whiteboard application interface. As described above, the whiteboard application refers to an application for a user to perform operations such as writing and displaying, and may be used to generate writing traces according to a writing track of the user on the whiteboard application interface, and may also be used to insert other multimedia elements such as graphics, pictures, forms, and the like on the whiteboard application interface. In the whiteboard application interface, a user can realize writing, drawing, erasing and other operations similar to those of an entity blackboard, and further has better digital functions of moving, storing, zooming, inserting pictures, adjusting colors, setting stroke weights and the like. Writing-based operations in whiteboard applications are a mature realization of the prior art and are not described in detail in this solution. In practical applications, the whiteboard application may also be named as a whiteboard writing application, a writing application, an electronic whiteboard application, a collaborative whiteboard application, and the like, and the application for implementing the above functions is equivalent to the whiteboard application of the present embodiment regardless of changes in the names.

During the use of the whiteboard application, the whiteboard application is usually displayed in a full screen, that is, the whiteboard application fills up the display area 2 of the intelligent interactive tablet 1 in fig. 2, and for clarity, only the display change of the display area 2 is illustrated in the following figures. Referring to fig. 3, in addition to the contents (writing handwriting 22a and writing handwriting 22c) added during the use and the contents (not shown in fig. 3) inserted into the whiteboard application interface 20, there are various tool controls for operating the above contents, which are normally displayed in the toolbar 21 in the whiteboard application interface 20, and in the exemplary description of the present embodiment, the toolbar 21 is displayed at the bottom of the whiteboard application interface 20, and may also be displayed on the left and/or right side, or even on the left, right, and bottom in the actual layout. Some tool controls in the toolbar 21 correspond to digital implementation of the function of the entity blackboard, such as writing, erasing, turning pages (part of the entity blackboard is available), and other tool controls are function supplement controls implemented on the basis of the whiteboard application, such as cancel input, restore input, handwriting selection, insertion, and the like.

In this embodiment, at least one writing script is selected by the handwriting windowing operation, and the selected writing script is displayed in a window, that is, the handwriting windowing operation is a combination operation.

Specifically, in the present solution, the handwriting windowing operation may be a combined operation implemented based on the toolbar 21, as shown in fig. 3, a tool control for handwriting windowing is arranged in the toolbar, and first, one or more handwriting are selected through touch operations such as long pressing or circle selection, and then the tool control corresponding to the handwriting windowing is triggered, and when the above actions are detected, it is confirmed that a group of completed handwriting windowing operations is completed. Specifically, one or more handwriting is selected through touch control operations such as long-time pressing or circle selection, and then the selected handwriting is confirmed to be needed to be subjected to handwriting windowing display in a preset gesture (such as single-finger double-click and multi-finger single-click) mode and the like in an associated area (such as a closed area of circle selection and a circumscribed rectangle of the selected handwriting) of the handwriting. Or after triggering the tool control corresponding to the handwriting windowing, firstly displaying the handwriting window, then dragging the selected handwriting to the handwriting window after selecting one or more handwriting by touch control operations such as long pressing or circle selection, and the like, thereby realizing the windowing display of the selected handwriting.

And S102, opening a handwriting window, and displaying the writing handwriting selected according to the handwriting windowing operation in the handwriting window, wherein the handwriting window is arranged on the whiteboard application interface.

The content displayed in the whiteboard application interface of the whiteboard application can be regarded as display elements in the whiteboard application interface, such as handwritten characters input by touch, drawings input by touch, and inserted pictures. The handwriting window triggered by handwriting windowing operation is also one of display elements in the whiteboard application interface, and the difference is that other display elements confirm display levels according to an input sequence, the later the input is, the display levels are higher, but the handwriting window has the highest display level, the top display state of the handwriting window is permanent relative to other real-time input display elements in the use process of the whiteboard application, and the display state of the handwriting window can only be influenced by other same-level handwriting windows and is not influenced by other real-time input display elements.

The handwriting 22a in fig. 3 is used as the target handwriting for the handwriting windowing operation, the display effect as shown in fig. 4 can be obtained, the handwriting window 23a is marked by a rectangular frame, and the handwriting 22a selected by the handwriting windowing operation is completely located in the handwriting window 23 a. White filling, filling with certain transparency or colorless filling can be selected in the rectangular border, and corresponding options can be popped up for confirmation when the tool control of handwriting windowing is triggered. Different filling is specifically performed according to different display requirements, for example, when the handwriting window 23a is needed to perform comparative analysis, in order to avoid interference of the writing 22a in the handwriting window 23a by the writing with a low display level, white filling can be performed on the handwriting window 23 a; for example, two writing scripts need to be subjected to overlapping comparison, and the handwriting window 23a can be filled in semi-transparent or colorless, so that the difference between the two parties can be visually seen. It should be appreciated that the selected handwriting is no longer displayed on the whiteboard application interface after it is displayed in the handwriting window.

In general, the handwriting window can be regarded as a virtual whiteboard defined and displayed in the whiteboard application interface, and each whiteboard independently responds to writing operations in the area thereof, so that a plurality of virtual electronic whiteboards can be realized through one physical electronic whiteboard under the whiteboard application framework, and the use requirements of a plurality of users for simultaneous operations can be applied.

Step S103: receiving handwriting editing operation generated on the whiteboard application interface or the handwriting window, and adjusting the handwriting corresponding to the whiteboard application interface or the handwriting window according to the handwriting editing operation.

And if the handwriting editing operation meets a preset condition, confirming the handwriting editing operation occurring in the handwriting window, and adjusting the writing handwriting of the handwriting window, otherwise, confirming the handwriting editing operation occurring in the whiteboard application interface, and adjusting the writing handwriting of the whiteboard application interface.

It is understood that the preset condition may be one of many ways, for example, whether the starting point of the handwriting editing operation is in the handwriting window, if the starting point of the handwriting editing operation is in the handwriting window, the handwriting editing operation occurring in the handwriting window is confirmed, otherwise, the handwriting editing operation occurring in the whiteboard application interface is confirmed.

For another example, the preset condition is whether the handwriting window is in a selected state during handwriting editing operation, if so, the handwriting window is determined to be the handwriting editing operation occurring in the handwriting window, otherwise, the handwriting window is determined to be the handwriting editing operation occurring in the whiteboard application interface. It will be appreciated that the handwriting window may be placed in a selected state by a preset gesture operation (e.g., double-clicking the handwriting window) or menu selection prior to the handwriting editing operation.

The writing and editing operation mainly comprises writing operation and erasing operation, wherein the writing operation is used for inputting writing handwriting, and the erasing operation is mainly used for erasing the drawn writing handwriting.

In this embodiment, the writing editing operation performed on the whiteboard application interface or the handwriting windowing operation is similar to the overall implementation of the conventional writing operation in the prior art, and the local part can be adjusted adaptively to the handwriting window. The main adjustments of the writing editing operation are the definition of the area of influence at the beginning of the operation and the definition of the editing drawing adjustment during the operation. Specifically, in which area (whiteboard application interface or handwriting window) the start point of the writing editing operation is, the entire operation process is valid only for that area. For example, if the starting point of the handwriting corresponding to a certain writing operation is not in the handwriting window, the writing operation is confirmed to be effective on the whiteboard application interface, the writing handwriting is only correspondingly generated on the whiteboard application interface, and if the writing handwriting is overlapped with the handwriting window, the overlapped part is generated below the handwriting window so as to adapt to the top display of the handwriting window. For example, if the starting point of the writing corresponding to a certain writing operation is within the writing window, it is determined that the writing is corresponding to the writing behavior in the writing window, the writing overlapping with the writing window is generated in the writing window, and the part of the writing operation not overlapping with the writing window is not generated and displayed. The erasing operation is similar to the writing operation in the processing process, and one erasing operation corresponds to one handwriting window or the writing handwriting in the whiteboard application interface. As shown in fig. 6, on the basis of fig. 5, a new writing script 22b is added to the script window 23b by a writing operation.

Based on this embodiment, in some writing scenarios, for example, during a meeting activity, a user may write a meeting schema on a whiteboard application interface first, and simply provide several meeting schemas, so that based on each meeting schema, a handwriting window may be generated to display the meeting schema, and a specific meeting record may be written and added in each handwriting window based on the corresponding meeting schema, and finally, the writing scripts of all the handwriting windows may be combined into the whiteboard application interface to form a complete meeting record. Or only one handwriting window can be generated, and after each meeting outline is displayed in the handwriting window, the meeting outline is written and edited in the handwriting window, and after the meeting outline is finished, the written content is moved to the whiteboard application interface, then the next meeting outline is displayed in the handwriting window, the writing and editing is continued, and finally, the written handwriting aiming at all the meeting outlines are combined into the whiteboard application interface to form a complete meeting record. According to the scheme of the embodiment, various forms of activity organization modes including activities such as conferences, teaching and answering can be realized, various batch operations and adjustments are performed on writing handwriting according to specific needs based on the scheme provided by the embodiment, display adjustment of specific handwriting can be simplified, and a complex operation process is not needed.

Example two

Fig. 7 is a flowchart of a writing operation method of an intelligent interactive tablet according to a second embodiment of the present invention. The present embodiment is embodied on the basis of the above-described embodiments.

Specifically, referring to fig. 7, the writing operation method of the intelligent interactive tablet provided in this embodiment specifically includes:

step S201, receiving handwriting windowing operation generated on a whiteboard application interface.

The handwriting windowing operation may be based on explicit handwriting confirmation (i.e., firstly selecting the handwriting and then confirming the handwriting windowing), or based on pending handwriting confirmation (i.e., firstly confirming the handwriting windowing and then confirming the handwriting), in the whiteboard application interface shown in fig. 5, the handwriting window 23a is confirmed based on the explicit handwriting 22a, the handwriting window 23b is confirmed based on the pending handwriting, and the handwriting may be subsequently added to the handwriting window 23b by moving the handwriting or the writing operation.

And S202, opening a handwriting window to display the handwriting selected according to the handwriting windowing operation, wherein the handwriting window is arranged on the whiteboard application interface.

The handwriting window is arranged on the whiteboard application interface, not only is the display state just displayed, but also can be further continued to have the highest display level in the whole duration of the handwriting window, namely the handwriting window is arranged on the top for display. The top-positioned display in this embodiment is not absolutely positioned on all the existing display elements, but is positioned relatively on the display elements input in real time in the whiteboard application interface. The display position of the handwriting window is usually confirmed by handwriting, and the centrally displayed handwriting is not usually displayed to different handwriting windows in terms of interaction requirements. In addition, even if the handwriting windows formed by the correspondence of the two writing scripts with the closer distance have intersection, the handwriting windows only do symbolic rectangular frame marks, the frames can be set to be thinner lines, and when the frames have intersection with other display elements, the display of other display elements cannot be influenced.

Step S203: receiving handwriting editing operation generated on the whiteboard application interface or the handwriting window, and adjusting the handwriting corresponding to the whiteboard application interface or the handwriting window according to the handwriting editing operation.

The step S203 is the same as the step S103 of the first embodiment, and the description will not be repeated here.

Step S204: and when receiving display adjustment operation in the whiteboard application interface, changing the display position of the display element of which the display level is lower than the handwriting window in the whiteboard application interface, and keeping the display position of the handwriting window.

In the present embodiment, it is emphasized that, in the adjustment of the display position of the display element generated in real time, the handwriting window does not respond, that is, the adjustment only changes the display position or the display content of the display element outside the handwriting window, and the handwriting window maintains the position in the display screen unchanged. By the operation mode, the existing display elements needing to be contrasted and explained can be adjusted to the adjacent position of the handwriting window by taking the handwriting window as reference, so that information audiences can intuitively feel the two parties in the explanation process. For example, the operations such as adjusting the size ratio (changing the display range) by multi-finger zooming, adjusting the display position (changing the display position) by multi-finger dragging and the like can be adapted to the adjustment of the handwriting window by directly using the existing whiteboard application use experience, and the operation process is simple.

The application scenes of the whiteboard application mainly include meeting, teaching, brainstorming and other interactive scenes, and under the scenes, an active focus is usually generated, for example, a mathematical question is input by handwriting in the teaching process for explanation. In the process of explaining the mathematical questions, if the mathematical questions are complex, a larger blank is needed to record the problem solving step in the display area 2 applied to the whiteboard, and the display area 2 possibly removes the blank left by the display of the mathematical questions and is not enough to support the record of the problem solving step. For example, a certain product needs to be analyzed in a centralized manner in the process of a brainstorming, the basic idea of the product is input in the early stage of the brainstorming in a handwriting input mode, supplemented product improvement points are more and more along with the progress of the brainstorming, a new blank area is needed for subsequent recording, the basic idea of the product is displayed in a handwriting window through handwriting windowing operation, and the existing records are moved out of the display area to obtain more blank areas. For example, in the process of a conference, a plurality of solutions are formed for an issue at different times, wherein two solutions are better, but because the conference records between the two solutions are more, the records of the two solutions cannot be displayed in a proper size in a display area at the same time, at this time, the record of one solution can be selected to trigger handwriting windowing operation, the handwriting window is displayed on a handwriting window, then the display of a whiteboard application interface is adjusted, the display of the other solution is adjusted to be close to the handwriting window while the display position of the handwriting window is kept unchanged, the two solutions can be displayed in a contrasting manner, and further contrastive analysis discussion is carried out; the handwriting window can be adjusted to be close to another solution, new supplementary content is correspondingly added into the handwriting window in the subsequent discussion process, and the handwriting of the same solution is recorded in the same handwriting window, so that the display layout of the handwriting corresponds to the specific content structure, and better experience is provided from the aspects of display effect and adjustment operation.

In the display screen shown in fig. 4, if the page enlarging operation shown in fig. 8 is detected (the two-finger expansion triggered page enlarging operation is shown in fig. 8), the display of the handwriting window 23a remains unchanged, and correspondingly, the display of the handwriting 22a in the handwriting window 23a also remains unchanged, and only the display elements outside the handwriting window 23a respond to the page enlarging operation, for example, the handwriting 22c is enlarged and displayed in the whiteboard application interface to obtain the handwriting 22 c'.

Preferably, the present embodiment further comprises:

step S205: and when the click operation of the closing control is received, displaying the writing in the writing window to the whiteboard application interface, and closing the writing window.

The handwriting window displays a closing control for terminating the display of the handwriting window. In this embodiment, the writing handwriting displayed in the handwriting window is not an invalid writing handwriting input temporarily, but is also an effective record generated in the whiteboard application use process, and the display adjustment required to be performed based on information presentation is displayed in the handwriting window, so that the recording requirement of the writing handwriting is not affected, and therefore, when the handwriting window is closed, the remaining writing handwriting in the handwriting window is displayed on the whiteboard application interface. As shown in fig. 9, the closing of the handwriting window 23a and the handwriting window 23b is performed on the basis of fig. 6, and this closing operation does not affect the continuous display of the original handwriting, as shown in fig. 10, the handwriting 23a and the handwriting 23b are continuously displayed on the whiteboard application interface.

The handwriting window is used as a temporary display interaction mechanism and can be automatically closed when the whiteboard application interface is closed, wherein the original displayed handwriting can be kept in the whiteboard application interface to be synchronously stored with other display elements. Of course, the handwriting window and the handwriting therein may be selected to be stored synchronously with other display elements when the whiteboard application interface is closed.

Preferably, the present embodiment further comprises:

step S206: and when receiving a track moving operation, moving the writing handwriting selected by the track moving operation to a target area where the end point of the track moving operation is located, wherein the target area is a handwriting window or a whiteboard application interface.

The principle of the track moving operation is the same as the conventional movement in the whiteboard application, and the optimization in this example is to determine whether to adjust the display area where the moving handwriting is located according to the position of the end point of the track moving operation. Specifically, a first track moving operation is received, and the writing handwriting selected from the whiteboard application interface according to the first track moving operation is moved to the handwriting window. And when the first track moving operation is confirmed to be completed, moving the selected writing track from the whiteboard application interface to the handwriting window. And receiving a second track moving operation, and moving the writing handwriting selected by the second track moving operation from the handwriting window to the whiteboard application interface. And when the second track moving operation is confirmed to be completed, moving the selected writing track from the handwriting window to the handwriting window. And receiving a third track moving operation, and moving the handwriting selected from the first handwriting window to a second handwriting window where the end point of the third track moving operation is located according to the third track moving operation. And when the third track moving operation is confirmed to be completed, the selected writing track is moved from the handwriting window to another handwriting window (namely, the handwriting window where the end point is located). In the detail processing of the movement, if the moved handwriting is crossed with the rectangular frame of the handwriting window, the size of the handwriting window needs to be adjusted so that the related handwriting is completely displayed in the handwriting window, and the movement process can be the movement of the original handwriting or the movement of the original handwriting is not kept.

Based on the operation, in some scenes that multiple persons write comprehensively, for example, multiple persons comprehensively perform open drawing in a drawing class, simple groups of drawing lines are provided, so that each person can generate a handwriting window based on any group of drawing lines, a limited number of drawing lines are added on the basis that each handwriting window is based on any group of drawing lines, and finally the drawing lines of all handwriting windows are combined into a whiteboard application interface to form a complete drawing, thereby training divergent thinking. In operation, in order to record the drawing process of each person, each person can create a handwriting window, and then move an existing set of drawing lines or a part of a set of lines into the newly created handwriting window, and complete the relevant drawing operation. On the whole, based on the movement of writing the orbit, can realize the manifold activity organization mode of various forms, design the activity link according to concrete activity purpose (for example teaching content, meeting theme), provide abundant effectual technical support through this scheme, reinforcing activity effect.

Preferably, the present embodiment further comprises:

step S207: and when receiving the moving operation generated in the handwriting window, moving the display position of the handwriting window.

When the trace roaming is actually performed, the operation purpose may be to perform a comparison description with other display elements in the whiteboard application interface, and the handwriting window may just cover an object that needs the comparison description, and at this time, the display position of the handwriting window may be adjusted through a moving operation in the handwriting window. In the specific adjusting process, the handwriting window may perform the same display position adjustment following the moving track of the moving operation, that is, a part of the handwriting window may not be displayed in the whiteboard application interface; or the handwriting window can be automatically adjusted within a certain constraint range along with the moving track of the moving operation. For example, when the boundary of the handwriting window moves to the outside of the set boundary of the whiteboard application interface, after the moving operation is finished, the handwriting window is retracted and hidden to the boundary of the whiteboard application interface, that is, when the handwriting window moves to the outside of the set boundary, the handwriting window is automatically and integrally moved to the boundary, so that the handwriting window is not continuously displayed in the whiteboard application interface, the integrally hidden display effect is achieved, especially, the display of other handwriting or new writing operation is influenced for the display of the handwriting window, and when the handwriting window is not necessarily displayed at present, the hiding of the handwriting window can be realized through the operation, and the interference to other handwriting or subsequent writing operation is avoided.

As another optional automatic adjustment mode, the handwriting window moves to contact with the boundary of the whiteboard application interface along with the moving track at most, and the handwriting window does not move along with the moving component of the moving track in the direction, so that the complete display of the handwriting window is maintained. In addition, the combination of two automatic adjustment modes can be realized, for example, when the handwriting window in the whiteboard application interface is moved to the boundary, the handwriting window is attached to the boundary display, and if the handwriting window attached to the boundary display is moved to the outside of the boundary, the handwriting window is hidden to the boundary, so that different operation requirements of a user can be met, and for the operation requirement hidden to the boundary, the user only needs to restore the touch state and move outwards after finishing touching, and the operation process still has good continuity. Referring to fig. 11, the handwriting window 23a is located at the upper left corner of the whiteboard application interface 20 when initially appearing, and in response to the moving operation, the handwriting window 23a moves to a middle position of the whiteboard application interface 20, thereby generating a new handwriting window 23a 'in which the corresponding moved handwriting 22 a' is displayed.

In addition, the combination of following and complete display can be realized, specifically, the handwriting window performs the same display position adjustment following the movement track, but when the boundary of the handwriting window moves to the outside of the set boundary of the whiteboard application interface, after the movement operation is finished, the handwriting window is restored to the whiteboard application interface for display, and specifically, action effects such as rebounding, moving and the like can be added to the restoration process.

Based on the principle of complete display, if the handwriting selected by the handwriting windowing operation is not completely displayed in the display area at first, when the handwriting is displayed in the handwriting window, the display content in the display area needs to be finely adjusted, so that the handwriting window is ensured to be integrally displayed in the display area.

Preferably, the present embodiment further comprises:

step S208: and restoring and displaying the hidden handwriting window confirmed according to the window restoration operation after receiving the window restoration operation.

When the handwriting window is hidden, a mark can be displayed at a position correspondingly hidden at the boundary of the whiteboard application interface, when a track moving from the boundary to the center of the whiteboard application interface is detected in a mark range, the corresponding handwriting window is restored, and the display state of the handwriting window can be quickly recovered when the display requirement is met on the previously hidden handwriting window.

In addition to the specific window restoration operation corresponding to the handwriting window, the display of the handwriting window can be sequentially restored through other operations, the handwriting window is hidden at the boundary and can be regarded as being laid out outside the current display range of the whiteboard application interface, and when the current display range is processed, the display state of the hidden handwriting window can be possibly restored. Specifically, after the handwriting window is hidden, if a display adjustment operation, particularly a moving operation and a zooming operation, which occurs on the whiteboard application interface is received, the display elements hidden at the boundary can be displayed on the whiteboard application interface in response to the operation, wherein the hidden handwriting window is also included, the operation is equivalent to restoring the display of the handwriting window through adjustment at any position of the whiteboard application interface, and the operation experience is better. Of course, for the display adjustment operation that does not cause the display of the handwriting window, the handwriting window can still be kept at the boundary to be entirely hidden, so as to avoid the operation complexity when the display is restored after the adjustment of the whiteboard application interface is integrally followed.

In this embodiment, when the handwriting window is moved to a position outside the set boundary of the whiteboard application interface, the handwriting window is automatically moved to the boundary as a whole, so that the handwriting window is not displayed in the whiteboard application interface any longer, and an overall hidden display effect is achieved. And after elements of the whiteboard application interface or the whole writing operation page for performing writing, element editing and other operations are moved to a proper position, the handwriting window can be restored and displayed through window restoration operation, so that the content of the handwriting window and the content in the whiteboard application interface can be displayed in a contrast mode, or writing and editing can be continuously performed, and the user operation experience is better.

Step S209: and when the zooming operation occurring in the handwriting window is received, changing the display size of the handwriting window according to the zooming operation.

The initial size of the handwriting window is default, if the default display range is too large, the display of the content outside the handwriting window may be affected, and if the default display range is too small, the normal display of the content in the handwriting window may be affected. As shown in fig. 12, during the enlarging process of the handwriting window 20, the handwriting 23a therein is correspondingly enlarged, and the enlarged handwriting 22a ″ is displayed on the enlarged handwriting window 23a ″.

When the specific zooming is realized, the zooming operation can be realized through a hotspot operation, specifically, one or more corners of the handwriting window are set as zooming hotspots, when the zooming hotspot detects a dragging operation, the length and the width of the handwriting window are zoomed in the same proportion, and the display content in the handwriting window is also zoomed in the same proportion. In addition, multi-finger zooming operation can be performed on the handwriting window, corresponding size adjustment can be performed according to the change state of the relative distance between the fingers, and the specific adjustment mechanism is the same as that of the hot area operation, and is different from the triggering mode and the zooming center.

In addition, because the smart interactive tablet also supports mouse operations, operations of zooming and panning can also be implemented by a mouse.

It should be noted that the above steps are not performed in a particularly strict order, and the above numbering and description order is merely to accommodate the expression in fig. 7. In fact, in a complete usage cycle of the whiteboard application, as long as there is a prerequisite basis for executing the steps, other steps may be correspondingly executed according to the determination result of the touch event.

In the foregoing description, it is not specifically emphasized that a certain operation only affects a handwriting window corresponding to the operation, and it should be understood that, in the above all operation processes, an operation only affects one handwriting window, that is, an operation occurring in one handwriting window only affects the handwriting window, and the operation is not fed back through other handwriting windows.

After the handwriting window is displayed, the display state of the display element in the whiteboard application interface can be adjusted while the handwriting window maintains the display state for the subsequent operation of the handwriting window and/or the whiteboard application interface, so that the display element in the whiteboard application interface is suitable for the normal display of the handwriting window in the activity process; the handwriting in the handwriting window can be moved out and added at any time, so that the operation object in the handwriting window can be adjusted in real time; the editing content is reserved when the handwriting windowing display is quitted, and the complete recording of the editing operation can be realized.

EXAMPLE III

Fig. 13 is a flowchart of a writing operation method of an intelligent interactive tablet according to a third embodiment of the present application. The writing operation method of the intelligent interactive tablet provided in the embodiment is applied to the same scene as the writing operation method of the intelligent interactive tablet provided in the embodiment. Referring to fig. 13, the writing operation method of the smart interactive tablet provided by the present embodiment includes:

step S301: and monitoring a touch operation instruction of the white board application interface.

While many touch events may be monitored at the whiteboard application interface, for example, a trigger corresponding to any one of the tool controls in the toolbar 21 in fig. 3 will generate a corresponding response, in this embodiment, if the monitoring of the touch events corresponds to the whiteboard application interface 20 in fig. 3, the comprehensive judgment of the handwriting selection and the triggering of the multiple selectable tool controls is specifically described.

Step S302: and judging the type of the touch operation instruction.

The type of the touch operation instruction is confirmed according to parameters obtained by touch detection such as the position, duration, moving distance and the like of a touch event, in the scheme, a handwriting windowing operation instruction and various handwriting and displayed processing instructions are mainly judged and follow-up response is carried out, and the acquisition of the parameters such as the specific position, duration, moving distance and the like is a conventional implementation of the touch technology and is not deeply described here. Specifically, the determining the type of the touch operation instruction includes:

Step S303: and when the touch operation instruction is judged to be a handwriting windowing operation instruction, adding a handwriting window on the whiteboard application interface, and adjusting the handwriting selected by the handwriting windowing operation instruction to the handwriting window for displaying.

In the whiteboard application interface, the display process of all the display elements is actually a drawing process, and the stacking sequence, the moving operation and the like of each display element are realized through hierarchical management. In the scheme, at least one top layer is defined for the whiteboard application interface, the top layer is specially used for managing handwriting windows, all the handwriting windows are added to the top layer, and all the handwriting windows in the top layer have the highest display level relative to other layers, namely are displayed on display elements of all other layers.

In a specific implementation process, an original layer is defined corresponding to the top layer, the original layer is used for drawing display elements generated in real time in the use process of the whiteboard application, and the display elements in the original layer are confirmed in drawing levels according to an adding sequence. The setting of the top map layer and the original map layer can be used for managing the image drawing in the display process and the touch event response, and overall, the touch events before the two levels are isolated from each other. Specifically, for a touch event starting from a display element in the top layer, only the display element in the top layer responds; for a touch event starting from a display element in the original layer, only the display element of the original layer responds.

The level of the top-setting layer is defined relative to the original layer, and if no handwriting window exists, the white board application interface can be free of the top-setting layer. That is, drawing of the handwriting window in the top-setting layer requires to firstly confirm whether the top-setting layer exists. Based on this, adding a handwriting window on the whiteboard application interface includes:

The process of drawing the writing in the writing window mainly displays the change of the hierarchy, specifically, the process of adjusting the writing selected by the writing windowing operation instruction to the writing window for displaying comprises the following steps:

Generally speaking, the writing is not to record the position of each pixel point, but to convert the writing into mathematical expression, and according to the mathematical expression, the writing is drawn and the thickness, line type and color are drawn.

Step S304: and when the touch operation instruction is judged to be a handwriting editing operation instruction, adjusting the handwriting corresponding to the whiteboard application interface or the handwriting window according to the handwriting editing operation instruction.

In the above, the handwriting windowing operation generated on the whiteboard application interface is received; opening a handwriting window to display the writing handwriting selected according to the handwriting windowing operation, wherein the handwriting window is arranged on the whiteboard application interface; receiving handwriting editing operation generated on the whiteboard application interface or the handwriting window, and adjusting the handwriting on the whiteboard application interface or the handwriting window correspondingly according to the handwriting editing operation; and if the handwriting editing operation characters are combined with a preset condition, confirming the handwriting editing operation occurring in the handwriting window, and adjusting the handwriting of the handwriting window, otherwise, confirming the handwriting editing operation occurring in the whiteboard application interface, and adjusting the handwriting of the whiteboard application interface. The handwriting generated in a specific range or by a specific user can be correspondingly generated in the independent handwriting window, so that the handwriting display adjustment can be rapidly performed by taking the handwriting window as a unit at any time in the display process of the handwriting window, the display operation of the handwriting of a specific target is simplified, and the operation friendliness of the target handwriting during multiple display adjustment or editing operation is improved.
