Each embodiment will be described in detail below.

Example one

FIG. 1 is a flowchart of a page interaction method of a smart interactive tablet according to Embodiment 1 of the present invention. The page interaction method of the smart interactive tablet provided in the embodiment can be executed by the operating device of the smart interactive tablet. The operating device of the smart interactive tablet can be implemented by software and/or hardware. The operating device of the smart interactive tablet can be two It can be composed of one or more physical entities, or it can be composed of one physical entity. For example, the operating device of the smart interactive tablet can be a mobile phone, an industrial control computer, and so on.

In order to facilitate understanding, in the embodiments, the smart interactive tablet is used as the actual carrier to exemplarily describe the detailed process of implementing the page interaction method of the smart interactive tablet. Among them, the smart interactive tablet can be an integrated device that controls the content displayed on the display tablet through touch technology and realizes human-computer interaction. It can integrate projectors, electronic whiteboards, screens, audio, televisions, and video conferences. One or more functions such as a terminal.

Generally speaking, as shown in FIG. 2, the smart interactive tablet 1 includes at least one display screen. For example, the smart interactive tablet 1 is equipped 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, a smart interactive tablet is provided. In some embodiments, the user can implement touch operations by touching the display screen with a finger or a stylus. Correspondingly, the smart interactive tablet detects the touch position, and Respond according to the touch position to realize the touch function. Typically, at least one operating system is installed on the smart interactive tablet, where the operating system may include an Android system, a Linux system, and a Windows system. In some embodiments, the smart interactive tablet can install at least one application with writing function. Among them, the application program may be an application program that comes with the operating system, and at the same time, an application program downloaded from a third-party device or server is also installed. Optionally, in addition to the writing function, the application also has other editing functions, such as inserting tables, inserting pictures, illustration graphics, drawing tables, and drawing graphics. Among them, the drawn table or figure is a standard element drawn by the computer. Computer-drawn standard elements can be understood as printed standard elements drawn by the intelligent interactive tablet, which are different from the elements written by the user.

On the touch screens of smart handwriting devices such as electronic whiteboards, electronic blackboards, digital tablets, smart conference tablets, etc., there is a writing area for displaying input content in response to the user's writing operation. When writing in the writing area, such as by touching When a pen or finger touches the touch screen, the touch screen can sense changes in current, voltage, or magnetic flux (corresponding to the setting type of capacitive touch screen, resistive touch screen or electromagnetic touch screen), and get the 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, can obtain the trajectory data of the writing trajectory input during each time the stylus or the user's finger presses and writes to lift and stops writing, according to the trajectory data The writing trajectory input by the user is displayed in the writing area of the touch screen in real time. Of course, the writing process can be writing, and any input process for displaying the operation track implemented on the touch screen of the smart handwriting device can be regarded as the writing process. In addition, according to the different display elements where the touch operation occurs, the touch operation can respond to the user's click, drag, and other operations. These different response methods are the same in the underlying coordinate processing. Generally speaking, the area where the touch writing occurs overlaps the area where the display is located, that is, the display area 2 shown in FIG. 2. Based on the hardware implementation of basic functions such as touch and display, the functions of the whiteboard application can be implemented on the smart interactive tablet. The embodiments of this solution are the implementation of the whiteboard application.

In some embodiments, referring to FIG. 1, the page interaction method of the smart interactive tablet may include:

Step S101: Receive a first touch operation that occurs on the whiteboard application interface, where the first touch operation is used to switch the display of the whiteboard application interface to a second display page.

Application interface refers to an interactive interface used by an application to receive and/or display information, such as a video playback application, whose interactive interface is mainly used to display changing video images; for real-time communication applications, its interactive interface is mainly used to receive recent information. The content input by the end user and the content input by the remote user are displayed; the interactive interface of the file editing application is mainly used to receive and display the content input by the user; the interactive interface of the browser application is mainly used to receive the user input And display the content of the webpage based on the keyword.

In this embodiment, the targeted application interface refers to the user interface presented during the use of the whiteboard application, that is, the whiteboard application interface. As mentioned earlier, the whiteboard application refers to the application for users to write, display and other operations. It can be used to generate writing handwriting based on the user's writing track on the whiteboard application interface, and can also be used to insert graphics, pictures, and pictures on the whiteboard application interface. Other multimedia elements such as tables. In the whiteboard application interface, users can implement operations such as writing, drawing, and erasing similar to a physical blackboard, and have better digital functions such as moving, saving, zooming, inserting pictures, color adjustment, and stroke thickness setting. The writing-based operation in the whiteboard application is the realization of related technologies, and will not be described in detail in this solution. In actual applications, the whiteboard application can also be named as whiteboard writing application, writing application, electronic whiteboard application, collaborative whiteboard application, etc. No matter how the name is changed, as long as the application is used to realize the above functions, it is equivalent to the whiteboard application of this application .

In the process of using the whiteboard application, the whiteboard application is usually displayed in full screen, that is, the whiteboard application will fill the display area 2 of the smart interactive tablet 1 in FIG. 2. For clarity, the subsequent drawings only illustrate the display change of the display area 2. Please refer to Figure 3, the content displayed in the whiteboard application interface 20 in addition to writing added content and inserted content displayed in the use process as the display element 22 (display element 22 in Figure 3 is an inserted picture), there are various corresponding Tool controls for operating the above content. These tool controls are normally displayed on the toolbar 21 in the whiteboard application interface 20. In the example description of this solution, the toolbar 21 is displayed at the bottom of the whiteboard application interface 20, which is also displayed in the actual layout. It can be displayed on the left and/or right, or even on the left, right, and bottom. Some tool controls in the toolbar 21 correspond to the digital realization of the physical blackboard functions, such as writing, erasing, turning pages (only available on some physical blackboards), etc., and some tool controls are functional supplementary controls implemented on the basis of the whiteboard application, such as cancel Input, restore input, handwriting selection, insert, etc.

The first touch operation in this embodiment is a type of operation, and this type of operation will cause the switching of the displayed page, such as adding a page, turning a page forward, turning a page backward, and so on. In the embodiment of this solution, adding a page is taken as an example for illustration. As shown in FIG. 3, the first display page in the whiteboard application interface 20 displays an inserted picture as the display element 22. The whiteboard application interface shown in FIG. 3 There are multiple tool controls on the right side of the toolbar 21 in 20, which are used to add pages, turn pages forward, and turn pages backward. Figure 3 shows the operation of the tool controls for adding pages. A touch operation (add page) occurs, and the second display page designated by the first touch operation is a blank page.

In terms of display relationship, the whiteboard application interface is covered with the entire screen of the smart interactive tablet. The display page is the organization method of the content displayed in the whiteboard application interface. The display elements in the display page can be added, zoomed, and deleted; the page can be newly added; Pages can be turned back and forth between multiple display pages. In this solution, the first display page and the second display page do not refer to a certain display page, but refer to display pages in two display states during a display page switching cycle, where the first display page is the detection of the first touch. The second display page is the page to be displayed according to the first touch operation. The definition of the second display page is maintained until the next time the first touch operation is detected. For example, there are a total of 3 display pages , The currently displayed page is the second page, and the user operation is to turn the page backward, then in the process of responding to the page-backward operation, the second page is the first display page, the third page is the second display page, and the first page is the second display page. Page 3 is the second display page until the next first touch operation; the next first touch operation of the user is to page forward, then in the process of responding to the page forward, page 3 is the first The display page, the second page is the first display page. During these two operations, the first page has nothing to do with the response of the page turning operation, and it is neither the first display page nor the second display page. Generally speaking, whether a page is the first display page or the second display page can be determined by its display state.

Step S102: According to the first touch operation, display a second display page 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 first display page currently displayed in Figure 3 to the second display page specified by the first touch operation (ie a blank page). Adding a page will result in a change in the total number of pages. It has been implemented in related whiteboard applications.

Step S103: On the whiteboard application interface, display the preview page of the first display page in a page display window; the page display window is displayed on the second display page.

The content displayed in the whiteboard application interface of the whiteboard application can be regarded as the display elements in the whiteboard application interface, such as handwritten text input by touch, drawing by touch input, inserted pictures, etc. The page display window is also one of the display elements in the whiteboard application interface. The difference is that other display elements are displayed in the order of input. The later the input, the higher the display level, but the page display window has the highest display level. , The display state on the page display window is permanent relative to other display elements input in real time during the use of the whiteboard application, and is not affected by other display elements input in real time. In fact, the input of the display elements is completed on the display page, and the second display page is displayed on the next layer of the page display window to ensure that the display level of the display elements drawn or added in the display page is lower than the page display window.

The preview page of the first display page can be realized by taking a screenshot, or by redrawing the handwriting and adding other elements correspondingly, or directly zooming out the first display page. It is understandable that as long as it is the content displayed in the page display window The content of the first display page is the same, that is, the page display window can be regarded as displaying the preview page of the first display page. The screenshot can be a complete screenshot or a simplified screenshot. Generally speaking, the size of the smart interactive tablet is relatively large. The large commercial smart interactive tablet now has 80 inches. The image data obtained based on the complete screenshot of the displayed content will be relatively large. Therefore, when the screenshot is taken, the displayed content can be adjusted to a certain extent. Reducing the ratio, such as reducing it by half or three-quarters, and then simplifying the screenshots, you can get a screenshot that can present the content of the corresponding display page, but at the same time does not occupy the cache space, and achieve a balance between the display effect and the storage space. Redrawing the handwriting is equivalent to extracting the display parameters of the handwriting in the first display page, and then drawing a proportionally reduced handwriting in the page display window with the size of the page display window as a reference.

Step S104: Receive a writing operation that occurs on the second display page.

Step S105: According to the writing operation, a writing track is generated on the second display page.

The writing operation that occurs on the whiteboard application interface in this embodiment is similar to the overall implementation of the conventional writing operation in the whiteboard application in the related art, and the parts can be adapted to the page display window. For example, if the starting point of the writing track corresponding to a writing operation is not within the page display window, confirm that the writing operation is valid and generate the writing track accordingly. If the writing track overlaps the page display window, the overlapping part will be generated in the page display window Below, in order to adapt to the top display of the page display window, the original overlapping writing track can only be displayed after the page display window is moved or the writing track is moved. For another example, if the starting point of the writing track corresponding to a certain writing operation is within the file display window, it is confirmed that the writing operation is invalid and the writing track is not generated.

After switching to displaying a blank page on the basis of Figure 3, in addition to writing content on the blank page, you can also add other display elements to the blank page. For example, insert two pictures as display elements 22 to get the image shown in Figure 4. The interface shows that the first display page includes the original blank page plus several display elements. During the process of adding display elements 22 to the blank page, if there is no operation on the page display window 23, the page display window 23 remains displayed The state remains unchanged, for example, the display position of the page display window 23 on the display screen remains unchanged, and its content remains unchanged. If the display restoration operation is received in the page display window, the display state of the display page corresponding to the preview page specified by the restoration operation is restored.

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

It should be noted that the second touch operation may be a gesture trigger or a control trigger, as long as the corresponding gesture or control trigger condition is preset. For example, the starting point of the gesture is in the display area of a preview page, and the end point is outside the page display window 23 and points to the center area of the whiteboard application interface 20, it is confirmed that the second touch operation is received, and it is confirmed that the display page corresponding to the preview page needs to be restored Another example is to set a recovery control in the page display window 23. When the recovery control is triggered (either touch trigger or mouse trigger), it can also be confirmed that the display status of the display page corresponding to the preview page needs to be restored. For another example, when a continuous tapping operation is detected in the page display window 23, it is confirmed 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 implementation, the second touch operation can also be defined as a type of the first touch operation. Based on this solution, the currently displayed display page is regarded as the first display page, and the preview page specified by the second touch operation The corresponding display page is regarded as the second display page, which can trigger step S101 and subsequent related operations. In other words, the second touch operation not only triggers the restoration of the display state of the display page corresponding to the preview page, but also the preview page Display to the whiteboard application interface, replacing the first display page currently displayed. 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 to replace the display page in FIG. 4. And the preview page of the display page in FIG. 4 is displayed in the page display window 23. That is, if a second touch operation is detected in the page display window 23 in FIG. 4, in response to the second touch operation in the whiteboard application interface 20, the corresponding display content includes: the display page shown in FIG. 3 , The page display window 23, the page display window 23 displays the preview page of the display page shown in FIG. 4.

Above, receiving a first touch operation that occurs on the whiteboard application interface, the first touch operation being used to switch to a second display page; according to the first touch operation, a second display page is displayed to replace the The first display page currently displayed on the whiteboard application interface; on the whiteboard application interface, a preview page of the first display page is displayed in a page display window; the page display window is displayed on the second display page; Receive a writing operation that occurs on the second display page; generate a writing trajectory on the second display page according to the writing operation; receive a second touch operation on the whiteboard application interface, and display the second touch Control the display page corresponding to the selected preview page. Add a page display window to the top of the whiteboard application interface, and display the preview page corresponding to the display page in the page display window.

Example two

Fig. 5 is a flowchart of a page interaction method of a smart interactive tablet according to the second embodiment of the present invention. This embodiment is modified on the basis of the above-mentioned embodiment.

Referring to FIG. 5, the page interaction method of the smart interactive tablet provided in this embodiment may include:

Step S201: Receive a first touch operation that occurs on the whiteboard application interface, where the first touch operation is used to switch to a second display page.

The first touch operation can be realized by triggering controls in the toolbar, and can also be realized by gestures. For example, two fingers slide left or right to turn pages backward or forward, and three fingers or more to slide left to add pages.

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

Step S203: On the whiteboard application interface, display the preview page of the first display page in a page display window; the page display window is displayed on the second display page.

As shown in FIG. 6, there may be two page display windows 23, and as shown in FIG. 7, there may also be one page display window 23. The number of page display windows 23 can be adjusted according to the total number of displayed pages. For example, when there is only one display page in total, the page display window 23 does not necessarily exist; when there are two display pages in total, only one page display window 23 is needed; there are 3 or more display pages in total, but the total number is not particularly large (for example, 4 Or 5), each display page can correspond to a page display window; when the total number of display pages is relatively large, 1-3 page display windows can be used to display the preview pages of 1-3 display pages, including One page display window displays the preview page of the previous display page by default.

In the actual implementation of the page interaction in this solution, the display is not restored directly after the display page is switched. During the use of the whiteboard application, there may be multiple writing, inserting, and erasing operations, which are limited by this solution. It is the processing mechanism when the display page is switched. Only when an operation event is triggered will there be a corresponding display change.

Step S204: Receive a writing operation that occurs on the second display page.

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

The effect of generating the writing track on the second display page is shown in FIG. 6. When there are multiple display pages, the writing track can be generated on the second display page currently displayed.

Step S206: Receive a second touch operation on the whiteboard application interface, and display a display page corresponding to the preview page selected by the second touch operation. For example, at this time, the preview page selected by the second touch operation is the preview page of the first display page, and the first display page is restored in this step. As described in the foregoing embodiment, here, the second touch operation is also functionally equivalent to the first touch operation mentioned in step S201, that is, after the first display page is restored, step S203 will be executed to display the page The window displays the preview page of the second display page. Simply put, when there are multiple display pages, each time the page is switched, the page display window displays the preview page of the currently displayed page and switches to the target display page, and the page display window is displayed on the target display page. When the display of a display page is restored through the preview page, it is also equivalent to page switching. At the same time as the display is restored, the preview page of the currently displayed page will also be displayed in the page display window.

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

Step S207: Receive a third touch operation that occurs in the page display window, and change the preview page displayed in the page display window.

The third touch operation is implemented by a predefined gesture. The third touch operation is used to change the preview page currently displayed in the page display window 23, and is mainly used to switch the displayed preview pages in batches when there are multiple display pages. As shown in Fig. 6, the third touch operation is realized by a left and 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 and right sliding gesture, for example, when sliding to the left, the preview is switched to the left. page. In FIG. 6, two page display windows 23 are displayed, and the preview pages corresponding to the two display pages can be sequentially switched and changed each time the third touch operation is performed. Of course, if three page display windows 23 are displayed each time, each third touch operation can sequentially switch and change the preview pages corresponding to the three display pages; if one page display window 23 is displayed each time as shown in FIG. The third touch operation can sequentially switch and change the preview page corresponding to a display page. 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 in the multi-display page can be quickly confirmed. As shown in Figure 7, on the basis of the third touch operation, the display restoration operation is confirmed by a downward gesture operation. Based on the display restoration operation, the second display page can be confirmed, and the preview page of the first display page is displayed at this time. And it is displayed to the page display window 23, and the second display page is also restored to the display state, and the display interface after the display restoration operation is shown in FIG. 8.

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

Step S208: Receive the editing operation that occurs on the first display page, and adjust the display elements of the first display page.

In this embodiment, the first display page generally refers to the current display page displayed on the current whiteboard application interface. The editing operation that occurs 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 related art. For example, pictures can be inserted (shown in Figure 4), touch writing (shown in Figure 7) Wait. The part can be adapted to the page display window. For example, if the starting point of the writing track corresponding to a writing operation is not within the page display window, confirm that the writing operation is valid and generate the writing track accordingly. If the writing track overlaps the page display window, the overlapping part will be generated in the page display window Below, in order to adapt to the display of the page display window on the whiteboard application interface, the original overlapping writing track can only be displayed after the page display window is removed. For another example, if the starting point of the writing track corresponding to a certain writing operation is within the page display window, it is confirmed that the writing operation is invalid and the writing track is not generated, thereby avoiding unnecessary writing tracks generated in the page display window and affecting the information in the preview page. Interference.

In this step, the user can write on the current display page of the whiteboard application interface, insert graphics, charts and other elements, or adjust the writing handwriting and other display elements, etc., to realize the editing of the displayed page.

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

Step S209: Receive the display adjustment operation that occurs in the first display page, change the display position of the display element in the first display page, and maintain the display position of the page display window.

The display adjustment operations that occur in the first display page are mainly to adjust the display position, size ratio, display page switching, etc. in the first display page. The adjustment object mainly refers to the real-time display of the first display page during the use of the whiteboard application. For the generated display elements (such as input writing traces, inserted pictures and tables, etc.), in related technologies, there have been operations such as zooming and moving of display elements. In this embodiment, it needs to be emphasized that the existing real-time The page display window does not respond to the adjustment of the display position of the generated display element, that is, this adjustment only changes the display position or display content of the display element outside the page display window. For example, multi-finger zoom to adjust the size and proportion (change the display range), multi-finger drag to adjust the display position (change the display position), etc. Directly use the existing whiteboard application experience to adapt to the adjustment of the page display window. The process is simple. For another example, when adjusting display elements whose display level is lower than that of the page display window, the display of the page display window remains unchanged, and the user can maintain the page display when there is insufficient blank space for writing operations on the first display page While the window is normally displayed, the blank area is expanded through the display adjustment operation, and the operation of expanding the blank area is simple and accurate, and does not affect the display of the page display window.

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

Step S210: Receive a moving operation that occurs in the page display window, and move the display position of the page display window accordingly.

In the actual display of the page preview page, the page display window may just cover the objects that need to be explained in the first display page. At this time, the display position of the page display window can be adjusted by moving the page display window to avoid incorrect The occlusion of the display elements in the second display page; in addition, for users, the page display window can be adjusted to a suitable position, so that they can view the position of the reading page by themselves, and combine the content in the preview page to make display input on the second display page . During the adjustment process, the page display window can be adjusted in exactly the same display position following the movement trajectory of the mobile operation, that is, part of the page display window may not be displayed in the whiteboard application interface; it can also be the page display window that follows the movement of the mobile operation. The trajectory is adjusted within a certain range of constraints. For example, the page display window can follow the movement trajectory to move to the boundary of the whiteboard application interface at most, and then the movement component of the movement trajectory in this direction, the page display window will no longer follow the movement to maintain the page display The complete display of the window.

Please refer to FIG. 9, when the page display window 23 initially appears, it is close to the upper left corner of the whiteboard application interface 20. In response to the moving operation, the page display window 23 moves to a position near the middle of the whiteboard application interface 20.

In addition, it is also possible to achieve a combination of follow and complete display. In some embodiments, the page display window follows the movement track to perform the same display position adjustment, but when the boundary of the page display window moves to the set boundary of the whiteboard application interface In addition, after the moving operation ends, restoring the page display window to the whiteboard application interface display can add action effects to the restoration process, such as bounce, move, etc.

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

Step S211: Receive a zoom operation that occurs in the page display window, and follow the zoom operation to change the display size of the page display window.

The initial size of the page display window is the default. If the range of this default display is too large, it may affect the display of content outside the page display window. If the range is too small, it may affect the content of the page display window. Normal display. Based on this, it is necessary to adjust the size of the page display window according to actual display requirements, that is, to perform a zoom operation.

When zooming is implemented, the zooming operation can be achieved through hot zone operations. In some embodiments, one or more corners of the page display window are set as zooming hotspots, and when a drag operation is detected in the zooming hotspot, The length and width of the page display window are zoomed in the same proportion, and the display content in the page display window is also zoomed in the same proportion, as shown in FIG. 10. In addition, the multi-finger zoom operation can also be performed in the page display window, and the corresponding size adjustment can be performed according to the change state of the relative distance between the multiple fingers. The adjustment mechanism can be the same as the hot zone operation, except that the trigger mode and the zoom center are different.

In addition, because the smart interactive tablet also supports mouse operations, zooming and panning operations can also be achieved through the mouse.

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

Step S212: When a state switching operation is received, the page display window is opened or disabled according to the state switching operation.

During the use of the whiteboard application, if the user does not currently need to preview other pages, or the display of the page display window interferes with the normal display of the first display page, the user can close the page display window through the state switching operation; correspondingly, The user can also open the page display window when there is a page preview requirement.

The state switching operation can be to set the preview control on the toolbar. If the preview control is currently enabled, the page display window will be disabled if the preview control is triggered; if it is currently disabled, the page display window will be opened when the preview control is triggered. Of course, the state switching operation can also be completed by the detection of the trigger gesture, which is similar to the setting of the preview control, because it only needs to switch between on and off, and only one trigger gesture can be set. Each time the trigger gesture is detected, the page will be changed. The display window switches to another state. Undoubtedly, two different trigger gestures and/or two different preview controls can also be set to enable and disable respectively.

When switched to the open state, the page display window can display the preview page of the display page that has been operated before the first display page, or the display page of the display page whose page number is the previous page of the first display page. In the disabled state, none of the operations on the displayed page will affect the display of the page display window, that is to say, the page switching operation will only generate corresponding feedback on the page display window when it is in the open state.

When the whiteboard application is opened, the default state of the page display window can be a user-defined setting, that is, the user-defined whiteboard application opens or disables the page display window when the whiteboard application is opened; it can also be based on the status confirmation of the page display state when the whiteboard application was closed last time. That is, when the page display state was on when it was closed last time, the whiteboard application was also on when it was opened, and when the page display state was off when it was closed last time, the whiteboard application was also closed when it was opened. In addition, the state of the page display window when the whiteboard application is opened can also be fixed, which can be switched by the user through a state switching operation during the process of using the whiteboard application.

In some embodiments, as described above, after the page display window is displayed, subsequent operations on the page display window and/or the first display page can adjust the display elements in the first display page while the page display window maintains the display state. The display state of the first display page makes the display elements in the first display page adapt to the normal display of the page display window, and can be adjusted concisely and accurately; it can also adjust the page display window while the display elements in the first display page maintain the normal display state. The display state of the page display window adapts to the normal display of other page display windows or display elements, with simple and precise adjustments, and provides convenient interaction as a whole. The state switching design of the page display window based on the state switching operation is also beneficial to users Operate according to actual needs to provide better information display and page interaction experience.

Example three

FIG. 11 is a flowchart of a page interaction method of a smart interactive tablet according to Embodiment 3 of this application. The page interaction method of the smart interactive tablet provided in this embodiment and the page interaction method of the smart interactive tablet provided in the above embodiments are applied in the same scenario. Referring to FIG. 11, the page interaction method of the smart interactive tablet provided in this embodiment includes:

Step S301: Monitor the touch operation instruction on the whiteboard application interface.

Many touch events can be monitored on the whiteboard application interface. For example, the triggering of any tool control in the toolbar 21 in Figure 3 will generate a corresponding response. In this embodiment, if it corresponds to the whiteboard application interface in Figure 3 The monitoring of 20 touch events describes the subsequent response to the triggering of the file display tool control.

Step S302: Determine the type of the touch operation instruction.

The type of touch operation instruction can be confirmed according to the touch detection parameters such as the location, duration, and movement distance of the touch event. In this solution, the page switching operation instruction and the display restoration operation instruction are mainly judged and subsequent responses are made. The acquisition of parameters such as position, duration, and movement distance can be a conventional realization of touch technology, and will not be elaborated here. Judging the type of the touch operation instruction may include:

It is monitored in the toolbar of the whiteboard application interface that the preset page switching operation tool controls (page forward, page backward, and page addition) are triggered, or the display restoration operation instruction is triggered, then Determine that the touch operation instruction is a page switching operation instruction;

If the touch event that triggers the restoration of the control is monitored in the page display window, or the set gesture to restore the display is monitored, it is determined that the touch operation instruction is a writing operation instruction.

Step S303: When it is determined that the touch operation instruction is the first touch operation instruction, a second display page corresponding to the first touch operation instruction is displayed on the whiteboard application interface to replace the whiteboard application interface The first display page currently displayed; the preview page of the first display page is displayed in a page display window; the page display window is displayed on the second display page.

The page switching operation instruction includes a page adding instruction;

When it is determined that the touch operation instruction is a page switching operation instruction, the preview page of the first display page is displayed on the whiteboard application interface, the preview page is displayed in the page display window, and the preview page is displayed in the page display window. The second display page confirmed by the page switching instruction displayed on the next layer includes:

In the whiteboard application interface, the page display window is a control displayed on the display elements generated in real time during the use of all whiteboard applications. In the whiteboard application interface, the display process of all display elements is actually the drawing process, and the stacking order of each display element , Mobile operations, etc., are achieved through hierarchical management. In this solution, at least one top layer is defined for the whiteboard application interface. The top layer is dedicated to managing page display windows. All page display window changes occur in the top layer. All page display windows in the top layer are relative It has the highest display level at other levels, that is, it is displayed on the display elements of all other levels. The display levels of the page display windows in the top layer are equal. In some embodiments, the page display window with the most recently detected operation is displayed on all pages Displayed above in the window.

In the implementation process, corresponding to the top layer, there is also an original layer defined. The original layer is used to draw the display elements generated in real time during the use of the whiteboard application. The display elements in the original layer basically interact with each other according to the order of addition. Confirmation of drawing levels. The settings of the top layer and the original layer are not only used for the management of image drawing during the display process, but also for the management of touch event response. On the whole, the touch events before the two levels are isolated from each other. In some embodiments, for touch events starting from a display element in the top layer, only the display element of the top layer responds; for touch events starting from a display element in the original layer, only the original layer The display element responds.

The level of the top layer is defined relative to the original layer. If there is no page display window, there can be no top layer in the whiteboard application interface. That is, the drawing of the page display window in the top layer needs to confirm whether there is a top layer.

When the display page is switched to the first display page, the preview page generated during the last switching can be deleted.

Step S304: When it is determined that the touch operation instruction is a second touch operation instruction, display the display page corresponding to the preview page selected by the second touch operation instruction.

Step S305: When it is determined that the touch operation instruction is a writing operation instruction, a writing track generated corresponding to the writing operation instruction is generated on the second display page.

Above, through the monitoring and type judgment of touch operation instructions, the independent display of the page display window is realized in the whiteboard application interface. The page display window and the original layer where each display page is located independently respond to touch events, improving the display The accuracy and smoothness of the page switching process. The operation of the page display window and the display page are independent of each other, which also improves the accuracy of the operation during the adjustment of the display page; when the person performing the writing display only needs to browse the content of other pages, they can view it through the display of the preview page. There is no need to switch the display page, and the whiteboard application interface is generally displayed on a large-sized smart interactive tablet, and the presence of the preview page will not affect the overall display effect. In addition, the page display window is displayed when multiple pages are displayed, and the page display window is not displayed when there is no need to switch the display page, so as to minimize the impact of the page display window on the displayed content of the display page.
