The following examples are described in detail.

Example one

Fig. 1 is a flowchart of a page interaction method of an intelligent interactive tablet according to an embodiment of the present invention. The page interaction method of the smart interaction tablet provided in the embodiment may be executed by an operating device of the smart interaction tablet, the operating device of the smart interaction tablet may be implemented in a software and/or hardware manner, and the operating 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 implemented by the page interaction method of the intelligent interactive tablet 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 a writing track input in the process of writing to lifting and stopping writing by a stylus or a finger of a user can be obtained, and the writing track input by the user is displayed in a 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 page interaction method of the smart interaction tablet specifically includes:

step S101, receiving a first touch operation generated on a whiteboard application interface, wherein the first touch operation is used for switching the display of the whiteboard application interface to a second display page.

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 whiteboard writing application, electronic whiteboard application, collaborative whiteboard application, etc., and the application for implementing the above functions is equivalent to the whiteboard application of the present application regardless of changes in the name.

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 writing the added content and inserting the displayed content as the display element 22 during the use process (the display element 22 in fig. 3 is an inserted picture), there are various tool controls for operating the above content, which are normally displayed in the toolbar 21 in the whiteboard application interface 20, in the example description of the present scheme, the toolbar 21 is displayed at the bottom of the whiteboard application interface 20, and may also be displayed on the left side and/or the right side, or even on the left side, the right side, and the 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.

The first touch operation in this embodiment is a type of operation, which may cause switching of a display page, such as adding a page, turning a page forward, turning a page backward, and the like. In the embodiment of the present disclosure, a page is added as an example, as shown in fig. 3, an inserted picture is displayed on a first display page in the whiteboard application interface 20 as a display element 22, a plurality of tool controls are arranged on the right side of a toolbar 21 in the whiteboard application interface 20 shown in fig. 3, and are respectively used for page adding, page forward turning, and page backward turning, an operation on the tool control for page adding is performed in fig. 3, it is determined that a first touch operation (page adding) occurs at this time, and a second display page specified by the first touch operation is a blank page.

In terms of specific display relation, the whole screen of the intelligent interactive flat panel is fully paved on the whiteboard application interface, the display page is an organization mode of specific contents displayed in the whiteboard application interface, and display elements in the display page can be added, zoomed and deleted; the page can be newly built and added; pages can be turned back and forth among the multiple display pages. In the scheme, the first display page and the second display page do not refer to a specific certain display page, but refer to display pages in two display states in a display page switching period, where the first display page is a page displayed when the first touch operation is detected, the second display page is a page to be displayed according to the first touch operation, and the definition of the second display page is maintained until the next time before the first touch operation is detected, for example, 3 display pages are total, the current display page is the 2 nd page, the user operation is page turning backward, in the process of responding to the page turning backward operation, the 2 nd page is the first display page, the 3 rd page is the second display page, and the 3 rd page is the second display page maintained until the next first touch operation; if the user turns the page forward next time in the first touch operation, the page 3 is the first display page and the page 2 is the first display page in the process of responding to the page forward turning, and in the two operation processes, the page 1 is irrelevant to the response of the page turning operation and is neither the first display page nor the second display page. In general, whether a particular page is a first display page or a second display page is determined by its display state.

And S102, displaying a second display page according to the first touch operation so as to replace the first display page currently displayed on the whiteboard application interface.

The response result of the first touch operation is to switch the currently displayed first display page in fig. 3 to a second display page (i.e., a blank page) specified by the first touch operation, and the total number of pages is changed by adding pages, which is specifically implemented in the existing whiteboard application.

Step S103: displaying a preview page of the first display page on the whiteboard application interface through a page display window; the page presentation window is displayed on the second display page.

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 page display window is also one of the display elements in the whiteboard application interface, and the difference is that other display elements confirm the display hierarchy in the input sequence, the later the input, the higher the display hierarchy, but the page display window has the highest display level, and the upper display state of the page display window is permanent relative to other real-time input display elements in the whiteboard application use process, and is not influenced by other real-time input display elements. In fact, the input of the display elements is completed on the display page, and the second display page is displayed at the next layer of the page display window, so that the display level of the display elements drawn or added in the display page is lower than that of the page display window.

The preview page of the first display page can be realized by screenshot, redrawing handwriting and correspondingly adding other elements, or directly displaying and reducing the first display page, and it can be understood that as long as the content displayed by the page display window is the same as that of the first display page, the page display window can be considered to display the preview page of the first display page. The screenshot can be a full screenshot or a simplified screenshot. Generally speaking, the size of an intelligent interactive panel is large, the size of a large commercial intelligent interactive panel is already 80 inches, and image data obtained based on a complete screenshot of display content is large, so that during specific screenshot, the display content can be reduced in a certain proportion, for example, the screenshot is reduced by half or three quarters and then simplified, the content capable of presenting a corresponding display page can be obtained, meanwhile, the screenshot does not occupy a cache space, and balance between a display effect and a storage space is realized. Redrawing the handwriting is equivalent to extracting display parameters of the handwriting in the first display page, and then drawing the scaled-down handwriting in the page display window by taking the size of the page display window as reference.

Step S104: and receiving writing operation occurring on the second display page.

Step S105: and generating a writing track on the second display page according to the writing operation.

In this embodiment, the writing operation performed on the whiteboard application interface is similar to the overall implementation of the conventional writing operation in the whiteboard application in the prior art, and the local part can be adaptively adjusted according to the page display window. For example, if the starting point of the writing track corresponding to a certain writing operation is not in the page display window, the writing operation is confirmed to be valid, and the writing track is correspondingly generated, if the writing track is overlapped with the page display window, the overlapped part is generated below the page display window so as to adapt to the top display of the page display window, and the original overlapped writing track can be displayed only after the page display window is moved away or the writing track is moved. For another example, if the starting point of the writing trace corresponding to a certain writing operation is within the file display window, the writing operation is confirmed to be invalid, and the writing trace is not generated.

After the blank page is switched to be displayed on the basis of fig. 3, in addition to writing content on the blank page, other display elements may be further added to the blank page, for example, after two pictures are inserted as the display elements 22, the interface schematic shown in fig. 4 is obtained, at this time, the first display page includes the original blank page plus a plurality of display elements, and in the process of adding the display elements 22 to the blank page, if the page display window 23 is not operated, the page display window 23 keeps the display state unchanged, for example, the page display window 23 keeps the display position on the display screen unchanged, keeps the content thereof unchanged, and the like. And if the display restoration operation is received in the page display window, restoring the display state of the display page corresponding to the preview page specified by the display restoration operation.

Step S106: and receiving a second touch operation on the whiteboard application interface, and displaying a display page corresponding to the preview page selected by the second touch operation.

Specifically, the second touch operation may be triggered by a gesture or a control, as long as a corresponding gesture or control triggering condition is preset. For example, if the starting point of the gesture is in the display area of a certain preview page and the ending point of the gesture is outside the page display window 23 and points to the central area of the whiteboard application interface 20, it is determined that the second touch operation is received and it is determined that the display state of the display page corresponding to the preview page needs to be restored; for another example, a restoring control is set in the page display window 23, and when the restoring control is triggered (either touch trigger or mouse trigger), it may also be determined that the display state of the display page corresponding to the preview page needs to be restored. For another example, when the continuous tapping operation is detected in the page display window 23, it is determined that the second touch operation is received, and the display state of the display page corresponding to the preview page needs to be restored.

In a specific implementation, a second touch operation may be further defined as one of the first touch operations, based on the scheme, the currently displayed display page is regarded as the first display page, and the display page corresponding to the preview page specified by the second touch operation is regarded as the second display page, so that step S101 and subsequent related operations may be triggered. In this embodiment, if the second touch operation is received based on the state shown in fig. 4, the display page shown in fig. 3 is restored to display in place of the display page in fig. 4. And displays the preview page of the display page in fig. 4 to the page presentation window 23. That is, if the page display window 23 in fig. 4 detects a second touch operation, in response to the second touch operation, the corresponding display contents in the whiteboard application interface 20 include: the display page shown in fig. 3, the page presentation window 23, and the page presentation window 23 show a preview page of the display page shown in fig. 4.

Receiving a first touch operation occurring on a whiteboard application interface, where the first touch operation is used to switch to a second display page; displaying a second display page according to the first touch operation to replace the currently displayed first display page of the whiteboard application interface; displaying a preview page of the first display page on the whiteboard application interface through a page display window; the page display window is displayed on the second display page; receiving writing operation occurring on the second display page; generating a writing track on the second display page according to the writing operation; and receiving a second touch operation on the whiteboard application interface, and displaying a display page corresponding to the preview page selected by the second touch operation. The method comprises the steps of adding a page display window in the whiteboard application interface, displaying a preview page corresponding to a display page in the page display window, and when the display page needs to be switched, restoring the display state of the corresponding display page through operation of the preview page, so that the accuracy and the smoothness in the display page switching process are improved. Further, in application scenes such as annotation or whiteboard writing, a display page before switching is displayed on a current display page in a page display window mode, and the page display window is fixed at the position of a screen and is visible, so that reference is provided for annotation or whiteboard handwriting; furthermore, the operation in the page display window and the display page is independent, so that the accuracy of the operation in the adjustment process of the display page is improved; when a person who performs writing display only needs to browse the contents of other pages, the contents can be viewed through the display of the preview page without switching the display pages, and for the intelligent interactive tablet, the position of the user who performs writing display is close to the intelligent interactive tablet, so that the information in the preview page can be clearly obtained, and the existence of the preview page does not influence the overall display effect.

Example two

Fig. 5 is a flowchart of a page interaction 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. 5, the page interaction method of the intelligent interactive tablet provided in this embodiment specifically includes:

step S201, receiving a first touch operation occurring on the whiteboard application interface, where the first touch operation is used to switch to a second display page.

The first touch operation is realized by triggering a control in a toolbar, and can also be realized by gestures, for example, double-finger leftward or rightward sliding indicates that pages are turned backwards or forwards, and three-finger and above leftward sliding indicates that pages are added.

Step S202, according to the first touch operation, displaying a second display page to replace a first display page currently displayed on the whiteboard application interface.

Step S203, displaying a preview page of the first display page on the whiteboard application interface through a page display window; the page presentation window is displayed on the second display page.

As shown in fig. 6, the number of the page display windows 23 may be 2, and as shown in fig. 7, the number of the page display windows 23 may also be 1. The specific number of the page display windows 23 can be adjusted according to the total number of the displayed pages. For example, when there is only one display page in total, the page presentation window 23 does not necessarily exist; when two display pages are total, only one page display window 23 is needed; there are 3 or more display pages in total, but when the total number is not particularly large (e.g., 4 or 5), there may be one page presentation window for each display page; when the total number of the displayed pages is larger, displaying the preview pages of 1-3 displayed pages through 1-3 page display windows correspondingly, wherein 1 page display window displays the preview page of the last displayed page by default.

When the page interaction in the scheme is actually executed, the display of the display page is not directly recovered after the display page is switched, a plurality of operations of writing, inserting and erasing can be performed in the using process of the whiteboard application, the scheme limits a processing mechanism when the display page is switched, and the corresponding display change can be performed only when a specific operation event is triggered.

Step S204: and receiving writing operation occurring on the second display page.

Step S205: and generating a writing track on the second display page according to the writing operation.

Effect of generating a writing trace on the second display page as shown in fig. 6, when there are a plurality of display pages, a writing trace may be generated on the currently displayed second display page.

Step S206: and receiving a second touch operation on the whiteboard application interface, and displaying a display page corresponding to the preview page selected by the second touch operation. For example, at this time, if the preview page selected by the second touch operation is the preview page of the first display page, the display of the first display page is resumed in this step. As described in the foregoing embodiment, the second touch operation is also functionally equivalent to the first touch operation mentioned in step S201, that is, after the display of the first display page is resumed, step S203 is executed to display a preview page of the second display page in the page display window. In short, when there are multiple display pages, each time page switching is performed, the preview page of the currently displayed page is displayed in the page display window, and is switched to the target display page, and the page display window is displayed on the target display page. When the display of a certain display page is restored through the preview page, the page switching is also performed, and the preview page of the currently displayed page is also displayed through the page display window while the display is restored.

Preferentially, the page interaction method of the embodiment further includes:

step S207, receiving a third touch operation occurring in the page display window, and changing a preview page displayed in the page display window.

The third touch operation is implemented by a predefined gesture, and the third touch operation is used to change the currently displayed preview page in the page display window 23, and is mainly used to switch the displayed preview pages in batch when multiple display pages exist. As shown in fig. 6, the third touch operation is implemented by a left-right sliding gesture within the range of the page display window 23, and the preview page displayed in the page display window 23 is adjusted by the left-right sliding gesture, for example, when the page is slid leftwards, the preview page is switched leftwards. In fig. 6, 2 page display windows 23 are displayed, and the preview pages corresponding to the 2 display pages can be sequentially switched and changed each time the third touch operation is performed. Of course, if 3 page display windows 23 are displayed each time, the preview pages corresponding to the 3 displayed pages may be sequentially changed by the third touch operation each time; if 1 page display window 23 is displayed each time as shown in fig. 7, the preview page corresponding to 1 displayed page may be sequentially changed by the third touch operation each time. On the basis of the third touch operation, when there are more display pages, the preview page displayed in the page display window 23 can be quickly switched, so that the second display page to be displayed when there are more display pages can be quickly confirmed. As shown in fig. 7, based on the third touch operation, the display restoration operation is confirmed by a downward gesture operation, the second display page can be confirmed based on the display restoration operation, at this time, the preview page of the first display page is displayed and displayed in the page display window 23, the second display page is also restored to the display state, and the display interface after the display restoration operation is displayed as shown in fig. 8.

Preferentially, the page interaction method of the embodiment further includes:

and step S208, receiving editing operation generated on the first display page, and adjusting display elements of the first display page.

In this embodiment, the first display page generally refers to a current display page displayed on the current whiteboard application interface. The editing operation occurring on the current display interface in this embodiment is similar to the overall implementation of the conventional editing operation in the whiteboard application in the prior art, and for example, a picture (shown in fig. 4), touch writing (shown in fig. 7) and the like may be inserted. The local part can be adjusted adaptively according to the page display window. For example, if the starting point of the writing track corresponding to a certain writing operation is not in the page display window, the writing operation is confirmed to be valid, and the writing track is correspondingly generated, if the writing track is overlapped with the page display window, the overlapped part is generated below the page display window so as to be suitable for the page display window to be displayed on the whiteboard application interface, and only after the page display window is moved away, the original overlapped writing track can be displayed. For another example, if the starting point of the writing track corresponding to a certain writing operation is in the page display window, the writing operation is determined to be invalid, and the writing track is not generated, so that the interference on the information in the preview page due to the generation of an unnecessary writing track in the page display window is avoided.

In this step, the user can write and insert elements such as graphics and diagrams in the current display page of the whiteboard application interface, or adjust the writing handwriting and other display elements, so as to edit the display page.

Optionally, the page interaction method of this embodiment further includes:

step S209: and receiving display adjustment operation generated in the first display page, changing the display position of the display element in the first display page, and keeping the display position of the page display window.

In the present embodiment, it is emphasized that, in the adjustment of the display position of the display element that has been generated in real time, the page display window does not respond, that is, the adjustment only changes the display position or the display content of the display element outside the page display window. For example, the adjustment of the size ratio (changing the display range) is realized by multi-finger zooming, the adjustment of the display position (changing the display position) is realized by multi-finger dragging, and the like, the adjustment of the page display window can be adapted by directly using the existing whiteboard application use experience, and the operation process is simple. For another example, when the display elements with the display levels lower than that of the page display window are adjusted, the display of the page display window is kept unchanged, so that the user can maintain the normal display of the page display window under the condition that the blank area for writing operation in the first display page is insufficient, and simultaneously expand the blank area through the display adjustment operation, expand the blank area, and operate the page display window in a concise and accurate manner without influencing the display of the page display window.

Optionally, the page interaction method of this embodiment further includes:

step S210: and receiving the moving operation generated in the page display window, and moving the display position of the page display window along with the moving operation.

When the page preview page is actually displayed, the page display window may just cover the object to be explained in the first display page, and at this time, the display position of the page display window can be adjusted through the moving operation of the page display window, so that the shielding of the display element in the second display page is avoided; in addition, for the user, the page display window can be adjusted to a proper position, so that the user can conveniently view the position of the browsing page, and further display and input are performed on the second display page by combining the content in the preview page. In the specific adjustment process, the page display window may perform the same adjustment of the display position following the movement track of the movement operation, that is, a part of the page display window may not be displayed in the whiteboard application interface; the page display window may also be adjusted within a certain constraint range along with the movement trajectory of the movement operation, for example, the page display window moves to contact with the boundary of the whiteboard application interface at most along with the movement trajectory, and the page display window does not move any more along with the movement component of the movement trajectory in the direction, so as to maintain the complete display of the page display window.

Referring to fig. 9, the page view window 23 initially appears in close proximity to the upper left corner of the whiteboard application interface 20, and in response to the move operation, the page view window 23 moves to a position at the center of the whiteboard application interface 20.

In addition, the following and complete display can be combined, specifically, the page display window performs exactly the same display position adjustment along with the movement track, but when the boundary of the page display window moves to the outside of the set boundary of the whiteboard application interface, after the moving operation is finished, the page display 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.

Optionally, the page interaction method of this embodiment further includes:

step S211: and receiving the zooming operation generated in the page display window, and changing the display size of the page display window along with the zooming operation.

The initial size of the page display window is default, if the range of the default display is too large, the display of the content outside the page display window may be affected, and if the range is too small, the normal display of the content in the page display window may be affected.

In a specific scaling implementation, the scaling operation may be implemented by a hotspot operation, specifically, one or more corners of the page display window are set as scaling hotspots, when a drag operation is detected in the scaling hotspots, the length and the width of the page display window are scaled by the same proportion, and the display content in the page display window is also scaled by the same proportion, as shown in fig. 10. In addition, multi-finger zooming operation can be performed on the page display window, corresponding size adjustment is performed according to the change state of the relative distance between the fingers, the specific adjustment mechanism is the same as that of the hot zone operation, and the difference is that the triggering mode and the zooming center are different.

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

Optionally, the page interaction method of this embodiment further includes:

step S212: and when state switching operation is received, opening or forbidding the page display window according to the state switching operation.

In the using process of the whiteboard application, if a user does not need to preview other pages at present, or the display of a page display window interferes with the normal display of a first display page, the user can close the page display window through state switching operation; correspondingly, the user can also open the page display window when the page preview requirement exists.

The specific state switching operation can be that a preview control is set in a toolbar, and if the toolbar is in an open state at present, the preview control is triggered, and then a page display window is forbidden; and if the current state is the forbidden state, triggering the preview control and opening the page display window. Of course, the state switching operation may also be completed by detecting the trigger gesture, which is similar to the setting of the preview control, because only switching between opening and disabling is required, only one trigger gesture may be set, and the page display window is switched to another state each time the trigger gesture is detected. Of course, two different trigger gestures and/or two different preview controls may be provided, respectively enabled and disabled.

When the display window is switched to the open state, the page display window may display a preview page of a display page operated before the first display page, or may display a preview page of a display page whose page number is one page before the first display page, which is not limited specifically. In the disabled state, the operation on the display page does not affect the display of the page display window, that is, the page switching operation generates corresponding feedback on the page display window only when the page display window is in the open state.

When the whiteboard application is opened, the default state of the page display window can be user-defined setting, namely the page display window is opened or forbidden when the user-defined whiteboard application is opened; or the state of the page display state when the whiteboard application is closed last time is confirmed, that is, when the page display state is opened when the whiteboard application is closed last time, the whiteboard application is opened, and when the page display state is closed when the whiteboard application is closed last time, the whiteboard application is closed when the whiteboard application is opened. In addition, the state of the page display window can be fixedly opened by the whiteboard application, and particularly, the user switches the state through state switching operation in the process of using the whiteboard application.

After the page display window is displayed, the subsequent operation on the page display window and/or the first display page can adjust the display state of the display element in the first display page while the display state of the page display window is maintained, so that the display element in the first display page is suitable for the normal display of the page display window, and the simple and accurate adjustment is performed; the display state of the page display window can be adjusted while the display element in the first display page maintains the normal display state, so that the page display window is suitable for normal display of other page display windows or display elements, simple and accurate adjustment is carried out, convenient interaction is integrally provided, the state switching design of the page display window based on state switching operation is also beneficial to a user to operate according to actual requirements, and better information display and page interaction experience is provided.

EXAMPLE III

Fig. 11 is a flowchart of a page interaction method of an intelligent interactive tablet according to a third embodiment of the present application. The page interaction method of the intelligent interactive tablet provided in the embodiment is applied to the same scene as the page interaction method of the intelligent interactive tablet provided in the embodiment. Referring to fig. 11, the page interaction method of the smart interaction tablet provided in this embodiment includes:

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

A number of touch events can 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, and in this embodiment, if the monitoring of the touch event corresponds to the whiteboard application interface 20 in fig. 3, a subsequent response in which the file presentation tool control is triggered is specifically described.

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

The type of the touch operation instruction is specifically determined 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 page switching operation instruction is mainly judged, a recovery operation instruction is displayed, and subsequent response is carried out, and the obtaining 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 further described herein. Specifically, the determining the type of the touch operation instruction includes:

monitoring that preset tool controls (forward page turning, backward page turning and page adding) of a page switching operation class are triggered in a toolbar of the whiteboard application interface, or monitoring that a display restoration operation instruction is triggered, and judging that the touch operation instruction is a page switching operation instruction;

and if a touch event triggering the recovery control is monitored in the page display window or a set gesture for recovering display is monitored, judging that the touch operation instruction is a writing operation instruction.

Step S303: when the touch operation instruction is judged to be a first touch operation instruction, displaying a second display page corresponding to the first touch operation instruction on the whiteboard application interface so as to replace the currently displayed first display page of the whiteboard application interface; displaying a preview page of the first display page by using a page display window; the page display window is displayed on the second display page.

The page switching operation instruction comprises a page adding instruction;

when the touch operation instruction is judged to be a page switching operation instruction, displaying a preview page of a first display page on the whiteboard application interface, wherein the preview page is displayed on a page display window, and a second display page confirmed by the page switching instruction is displayed on the next layer of the page display window, and the method comprises the following steps:

In the whiteboard application interface, a page display window is a control displayed on display elements generated in real time in the using process of the whiteboard application, the display process of all the display elements is actually a drawing process, and the stacking sequence, the moving operation and the like of all the display elements 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 the page display windows, the change of all the page display windows occurs in the top layer, all the page display windows in the top layer have the highest display level relative to other layers, namely the page display windows are displayed on the display elements of all other layers, the display levels of the page display windows in the top layer are equal, and particularly, the page display window which is detected to be operated recently is displayed on all the page display windows.

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 page display window exists, no top-setting layer can exist in the whiteboard application interface. That is, drawing of the page display window in the top map layer needs to first confirm whether the top map layer exists.

When the display page is switched to the first display page, the preview page generated at the last switching time may be deleted.

Step S304: and when the touch operation instruction is judged to be a second touch operation instruction, displaying a display page corresponding to the preview page selected by the second touch operation instruction.

Step S305: and when the touch operation instruction is judged to be a writing operation instruction, generating a writing track generated corresponding to the writing operation instruction on the second display page.

In the method, the independent display of the page display window is realized in the whiteboard application interface through the monitoring and type judgment of the touch operation instruction, the page display window and the original image layer where each display page is located respectively and independently respond to the touch event, and the accuracy degree and the smoothness degree in the display page switching process are improved. The operation in the page display window and the display page is independent, so that the operation accuracy in the adjustment process of the display page is improved; when a person who performs writing display only needs to browse the contents of other pages, the contents can be viewed through the display of the preview page without switching the display pages, and the whiteboard application interface is generally displayed on an intelligent interactive flat plate with a larger size, so that the overall display effect cannot be influenced by the existence of the preview page. In addition, the page display window is displayed when the pages are displayed in multiple ways, and the page display window is not displayed when the switching requirement of the displayed pages does not exist, so that the influence of the page display window on the displayed content in the displayed pages is reduced as much as possible.
