The technical solutions of the present application are described in detail below with reference to specific embodiments. The following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described in some embodiments.

FIG. 1 is a flowchart of Embodiment 1 of a document annotation method of the present application. The execution body of the embodiment may be a separate document annotation device, or may be an electronic device integrated with a document annotation device. The following is an example in which the execution body is a smart tablet integrated with a document annotation device. Referring to FIG. 1, the method provided in this embodiment may include:

S101. When entering the annotation mode, rendering the annotation layer on the currently displayed view; the annotation layer is used to render the annotation content based on the annotation event; the annotation event includes an add/drop/change event.

Specifically, the smart tablet can perform document presentation by running a local document program (for example, a PPT program or a Word program), or can perform a document presentation through a shared desktop, for example, a document presentation through a desktop shared by a computer, and HDMI input mode or VGA input mode for document presentation. For example, when presenting a document on a computer, connect the computer to the smart tablet through an HDMI cable or VGA cable, and display the document displayed on the computer on the smart tablet. It should be noted that whether the document is demonstrated through the shared desktop or the document is demonstrated through the HDMI input mode or the VGA input mode, the TOUCH line needs to be connected to the video signal input port of the smart tablet to implement touch return.

In addition, in this embodiment, the timing of entering the annotation mode is not limited, for example, the annotation mode may be entered when the document presentation is started; or the annotation button may be only rendered when the document presentation is started, and further, when the incoming annotation mode is received When the command is executed (it needs to be explained that the entry into the comment mode command is triggered when the comment button is clicked) enters the comment mode. That is, the user needs to trigger the entry of the annotation mode instruction by clicking the annotation button, so that the document being presented enters the annotation mode.

It should be noted that the annotation layer can be a globally transparent layer that is rendered above the currently displayed view for rendering the annotation content based on the annotation event. For example, for Android, the globally transparent layer can be a SurfaceView, which has a separate drawing surface, and can perform annotating operations such as scribing, circle, writing, drawing, and the like in the independent drawing surface.

S102. Monitor an annotation event triggered by the user, and update the display content of the annotation layer according to the annotation event.

Specifically, after entering the annotation mode, the user can annotate the currently displayed view. At this time, the smart tablet monitors the annotation event triggered by the user, and updates the display content of the annotation layer according to the annotation event. In this way, the annotation content can be displayed on the annotation layer to achieve the predetermined presentation effect.

S103. When there is an update instruction, update the currently displayed view and the annotation layer, and the update instruction is triggered based on a page turning event.

It should be noted that, in this embodiment, the triggering manner of the page turning event is not limited. For example, the user can trigger the page turning event by sliding the currently displayed view left and right. A detailed embodiment will be given below to explain the triggering manner of the page turning event, which will not be described here.

In addition, the update instruction is triggered based on the page flip event, and when there is an update instruction, the currently displayed view and the annotation view described above are updated. In this way, you can update the currently displayed view and annotation layers in annotation mode to annotate the updated view on the updated annotation layer, update the view without exiting the annotation, and then, after updating the view, The annotation is started again, the user operation is simple, and the user experience is high.

The method provided in this embodiment, when entering the annotation mode, renders the annotation layer on the currently displayed view, monitors the user-initiated annotation event, and updates the display content of the annotation layer according to the annotation event, thereby updating the presence of the annotation layer. When the instruction is issued, the currently displayed view and annotation layers are updated, wherein the update instruction is triggered based on the page turning event. In this way, the currently displayed view and annotation layer can be updated in the annotation mode to annotate the updated view on the updated annotation layer, the multi-page document can be annotated, and the user operation is simple, the user experience Higher.

Optionally, in a possible implementation manner of the present application, when entering the annotation mode, the method further includes: rendering an operation control, where the operation control is used to trigger at least one of the following events: a page turning event and an annotation event.

Specifically, the action control can be a floating visible action control that can be rendered on top of the annotation layer. In addition, the operation control includes at least one of the following controls: a page forward control, a page backward control, an annotation color selection control, an eraser control, and an annotation pen control. In addition, you can also include save controls, scan code sharing controls, and mailing controls.

Optionally, in a possible implementation manner of the present application, the page turning event includes a page turning event triggered by the operation control.

Specifically, the user can trigger a page turning event by clicking an operation control, for example, when the user clicks the forward page turning control, the page turning event is triggered.

Further, when the page turning event includes the page turning event triggered by the operation control, when the data source device of the view is the local device, the method provided by the embodiment further includes: after the local device responds to the page turning event , get the updated data to update the currently displayed view.

Specifically, FIG. 2 is a schematic diagram of an application scenario of a document annotation method provided by the present application, which is shown in an exemplary embodiment. Referring to FIG. 2, in the application scenario shown in FIG. 2, the smart tablet performs a document presentation by running a local document program, and the data source device of the view currently displayed by the smart tablet is the local device. At this time, the user can click The page turning control is used to trigger a page turning event. For example, in the application scenario shown in FIG. 2, the user can trigger a page turning event by clicking the forward page turning control. Further, after the page turning event is triggered, the smart tablet responds to the page turning event to perform page turning. At this time, the smart tablet acquires the updated data to update the currently displayed view. It should be noted that in this case, The update instruction may be triggered when the page turning event is triggered, or may be triggered when the updated data is acquired.

In addition, when the page turning event includes the page turning event triggered by the operation control, when the data source device of the view is the peer device of the network connection, the method provided in this embodiment further includes: notifying the page turning event through the network The peer device receives the updated data from the peer device after the peer device responds to the paging event to update the currently displayed view.

Specifically, FIG. 3 is a schematic diagram of an application scenario of a document annotation method provided by the present application, which is illustrated by another exemplary embodiment. Referring to FIG. 3, in the application scenario shown in FIG. 3, the smart tablet performs document presentation through wireless screen technology, and the currently running program of the smart tablet is a shared desktop. For example, in the application scenario shown in FIG. 3, the smart tablet is demonstrated by a desktop shared by a computer, and the data source device of the view currently displayed by the smart tablet is a computer (of course, in the application scenario shown in FIG. 3) The smart tablet can also be used for document presentation via HDMI input or VGA input. At this time, as shown in FIG. 3, the user can trigger the page turning event by clicking the page turning control displayed on the smart tablet. Further, when the user triggers the page turning event by clicking the page turning control, the smart tablet can simulate the opposite end. The input event of the device (the peer device is a computer in the embodiment shown in FIG. 3) sends the page flipping event to the peer device, for example, simulates a mouse input event or a keyboard input event, and sends a page turning event to the peer device. In this way, the peer device responds to the received page turning event after receiving the page turning event. In a specific implementation, for example, a wireless screen transmission technology may be used, that is, a page turning event is sent to the peer device through a wireless screen device. Specifically, one end of the wireless screen device is connected to the smart tablet through the Wifi, and the other end is connected. Connect to your computer via the USB port. In this way, the smart tablet can first send the page turning event to the wireless screen device, and further, when the wireless screen device receives the page turning event, it will follow the USB HID (Human Inter Device) multi-touch protocol to turn the page event. Repackage and send the repackaged page flip event to the computer via the USB interface. In this way, after the peer device receives the page turning event, it responds to the page turning event.

It should be noted that, after the peer device responds to the page turning event, at this time, the smart tablet receives the updated data from the peer device, so that after the updated data is received, the currently displayed view is updated. It should be noted that, in this embodiment, the update instruction may be triggered when the page turning event is triggered, or may be triggered when the updated data is received.

Optionally, in another possible implementation manner of the present application, the page turning event includes a page turning event triggered by a peer device of the network connection, where the peer device is a data source device of the view; The method further includes: after the peer device responds to the page flipping event, receiving the updated data from the peer device to update the currently displayed view.

Specifically, FIG. 4 is a schematic diagram of an application scenario of a document annotation method provided by the present application according to another embodiment. Referring to FIG. 4, in the application scenario shown in FIG. 4, the smart tablet is demonstrated by a wireless screen technology, and the smart plane is The program currently running on the board is a shared desktop. For example, in the application scenario shown in FIG. 4, the smart tablet is presented by the desktop shared by the computer, and the data source device of the view currently displayed by the smart tablet is a computer (of course, in the application scenario shown in FIG. 4) The smart tablet can also be used for document presentation via HDMI input or VGA input. As shown in Figure 4, the user can trigger a page flip event by clicking the page flip button on the computer. It should be noted that when there is a page turning event in the computer, at this time, the update command is triggered, and the computer sends the update command and the updated data to the smart tablet. Further, after the smart tablet receives the update command and the updated data, , update the currently displayed view and the current annotation layer.

A more specific embodiment is given below for a detailed description of the document annotation method provided by the present application.

FIG. 5 is a flowchart of Embodiment 2 of the document annotation method of the present application. Referring to FIG. 5, the method provided in this embodiment may include:

S501. When entering the annotation mode, if the second annotation layer associated with the currently displayed view is locally stored, the second annotation layer is rendered on the currently displayed view, if the local is not stored and currently displayed. The second annotation layer associated with the view renders the newly created annotation layer on the currently displayed view.

Specifically, when entering the annotation mode, it may first determine whether a second annotation layer associated with the currently displayed view is stored locally, and if so, rendering the second annotation layer on the currently displayed view, if not , renders the newly created annotation layer on the currently displayed view. For example, when entering the annotation mode, the page number information of the currently displayed view is page 3. In this step, it is determined whether the second annotation layer associated with the third page view is stored locally, and then stored locally and When the second annotation layer associated with the third page view is rendered, the second annotation layer is rendered on the currently displayed view, and when the second annotation layer associated with the third page view is not stored locally, the currently displayed Render the newly created annotation layer on the view.

It should be noted that the second annotation layer associated with the currently displayed view may be an annotation layer with the page number information of the currently displayed view as the file name. In this step, it is determined whether the local storage is stored. The annotation layer of the file name with the page number information of the currently displayed view. In addition, the second annotation layer associated with the currently displayed view may also be an annotation layer whose file name stored in the association table is associated with the page number information of the currently displayed view, for example, the currently displayed view. The page number information is page 1, and the file name associated with the page number information is not stored in the relationship table, indicating that there is no second annotation layer associated with the currently displayed view.

The method provided in this embodiment, when presenting a certain document, first caches the current annotation layer and the currently displayed view before updating the annotation layer, and further, when the save instruction is received, the cached annotation is used. The layer is saved locally so that when the document is demoed again and you enter the annotation mode, the locally cached annotation layer can be rendered at On the view associated with it, to present the annotation content to the user, the user's needs can be further satisfied and the user experience can be improved.

S502. Monitor an annotation event triggered by the user, and update the display content of the current annotation layer according to the annotation event.

For details, refer to the description of the step S102 in the first embodiment, and the details are not described herein.

S503. When an update instruction exists, cache the current annotation layer with the currently displayed view, and update the currently displayed view.

Specifically, the specific implementation process and implementation principle of updating the currently displayed view can be referred to the foregoing description, and details are not described herein again.

The method provided in this embodiment, when there is an update instruction, first caches the current annotation layer and the currently displayed view before updating the currently displayed view. In this way, the annotation layer carrying the annotation content can be cached in association with the view. Further, when displaying the view associated with the cached annotation layer, the current annotation layer can be updated to the annotation layer associated with the currently displayed view, so that the annotation layer carrying the annotation content can be rendered To the user, the user's needs can be further satisfied and the user experience can be improved.

The following describes in detail the implementation process of associating the current annotation layer with the currently displayed view.

FIG. 6 is a flowchart of associating an annotation layer with a currently displayed view according to an exemplary embodiment of the present application. Referring to FIG. 6, in a possible implementation, an annotation layer may be used as follows. Associating the cache with the currently displayed view, the method includes the following steps:

S601. Obtain page number information of the currently displayed view.

Specifically, the page number information is a serial number of each page of the document being presented, for example, page 1, page 2, and the like. In addition, when the data source device of the view is the local device, at this time, the page information page of the currently displayed view can be obtained by calling a related function of a locally running document program (for example, a PPT program or a Word program). In addition, when the data source device of the view is a peer device connected through the network, the peer device may be requested to obtain the page number information of the currently displayed view, for example, the COM of the peer device may be invoked through the auxiliary program. Interface to get the page number information of the currently displayed view.

S602. Cache the current annotation layer and the page number information.

Specifically, in this step, the current annotation layer may cache the obtained page number information as a file name to cache the current annotation layer and the page number information. For example, the obtained page number information of the currently displayed view is page 3, and at this time, the current annotation layer is cached with a file name of 3.

FIG. 7 is a flow chart showing the association of an annotation layer with a currently displayed view, according to another exemplary embodiment of the present application. Referring to FIG. 7, in another possible implementation, the annotation layer may be cached with the currently displayed view according to the following method, and the method includes the following steps:

S701. Obtain page number information of the currently displayed view.

For details, refer to the description of step S601 in the specific implementation process and implementation principle of the step, and details are not described herein again.

S702. Cache the current annotation layer, the file name of the current annotation layer, and the above page number information.

Specifically, in this step, the annotation layer may be saved with another information as a file name, thereby saving the file name of the current annotation layer and the obtained association relationship of the page number information, so as to display the current annotation layer and the currently displayed layer. View associative cache. In an embodiment, the annotation layer may be saved as a file name when the annotation layer is created. For example, if the current annotation layer is the first annotation layer created, the annotation layer is 1 The file name is saved, and the file name of the annotation layer and the obtained page number information are saved in the association table (in this example, the file name 1 and the page number information 3 are saved in the association table).

For another example, the current annotation layer can also be saved as the file name when the annotation layer is created. For example, if the annotation layer is created at 9:30:05 seconds on August 30, 2017, the annotation is added. The layer is saved as a file name of 20170830093005, and the file name of the annotation layer and the obtained page number information are saved in the association table (in this example, the file name 20170830093005 and the page number information 3 are saved in the association table). In this way, through the association table, it can be known that the annotation layer associated with the view with the page number information 3 is the annotation layer with the file name of 20170830093005, that is, the association relationship between the view and the annotation layer is established, and subsequent updates are performed. If there is an annotation layer associated with the updated view, when the annotation layer is updated, the annotation layer can be directly updated to the annotation layer associated with the updated view, which further enhances the user experience.

S504. Determine whether the first annotation layer associated with the updated view is cached. If yes, go to step S507, and if no, go to step S508.

In combination with the above example, the page number information of the currently displayed view is page 3. For example, the page turning event is a page turning event. At this time, the page number information of the updated view is page 4, and at this time, it is determined whether the first annotation layer associated with the page 4 view is cached, and further When the annotation layer is cached with the page number information of the view as the file name, in this step, it is determined whether the annotation layer with the file name of the fourth page is cached; when the annotation layer is the file name with other information. And when the file name of the annotation layer and the page number information of the view are stored in the association information table, in this step, it is determined whether there is a file name associated with the fourth page in the association table, and further, when determining the association table There are files associated with page 4 After the name, further determine whether there is an annotation layer named after the file name.

For example, in an embodiment, when entering the annotation mode, the page number information of the currently displayed view is page 4, and the user first annotates the currently displayed view, and then, pages backward, and the current annotation map is The layer is cached with a file name of 4, and the currently displayed view is updated. After the update, the page number information of the currently displayed view is page 5, and then the page is forwarded forward, and the current annotation layer is set to 5 as a file. Name cache, at this time, the page number information of the updated view is 4, at this time, it is determined that there is a first annotation layer associated with the updated view (there is an annotation layer with a file name of 4).

S505. Update the current annotation layer to the first annotation layer.

When it is determined in step S504 that there is a first annotation layer associated with the updated view, the user has already annotated the view to be displayed after entering the annotation mode. In this step, the annotation layer is updated to the first A batch of annotation layers, in this way, the previous annotation content can be presented to the user, so that the user can re-annotize the previous annotation content, which can further meet the user's needs and improve the user experience.

S506. Delete the current annotation layer and render the newly created annotation layer on the updated view.

Specifically, when it is determined in step S504 that there is no first annotation layer associated with the updated view, it indicates that after entering the annotation mode, the user has not annotated the view to be displayed, and in this step, the current The annotation layer is deleted and the newly created annotation layer is rendered on the updated view so that the user can annotate the updated view on the newly created annotation layer.

S507. When receiving the instruction to exit the annotation mode, output an alert message to remind the user to save the cached annotation layer to the local.

Specifically, the cached annotation layer is deleted when exiting the annotation mode. Therefore, the method provided by the embodiment, when receiving the exit annotation mode instruction, outputs an alert message to remind the user to save the cached annotation layer. . In this way, the problem that the annotation layer is lost due to the user forgetting to save the annotation layer can be avoided, and the annotation layer carrying the annotation content can be saved to display the annotation content to the user again.
