Detailed Implementation

[0013] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0014] Those skilled in the art will understand that, unless otherwise stated, the singular forms “a,” “an,” “the,” and “the” used herein may also include the plural forms. It should be further understood that the word “comprising” as used in this application’s specification means the presence of the stated feature, integer, step, or operation, but does not preclude the presence or addition of one or more other features, integers, steps, or operations.

[0015] refer to Figure 1 , Figure 1 This is a schematic diagram of an example all-in-one teaching blackboard. The blackboard includes a main touchscreen and secondary touchscreens located on either side of the main touchscreen. The example shown is a two-sided layout, including both a first and a second touchscreen. In practical applications, this can be expanded to include more secondary touchscreens. Furthermore, the secondary touchscreens can also be arranged vertically or in other forms, which will not be elaborated upon here. Users can perform touch writing operations on the main touchscreen or write on the secondary touchscreens. However, because the current writing content cannot be efficiently saved when the blackboard is filled and then erased, it is necessary to repeat the writing process multiple times, affecting the usability of the all-in-one teaching blackboard.

[0016] To address one of the aforementioned technical deficiencies, this application provides a method for processing touch-written content on the main touchscreen of an all-in-one teaching blackboard, which efficiently saves the written content and erasure information of the secondary touchscreen.

[0017] For ease of description, the following embodiments are based on... Figure 1 The description will be based on the two sub-touchscreens shown, the first touchscreen and the second touchscreen.

[0018] refer to Figure 2 As shown, Figure 2 This is a flowchart of a method for processing touch-written content according to one embodiment, which mainly includes the following steps: S10, based on the whiteboard software running on the main touch screen, the original touch point coordinate data of the touch writing content of the secondary touch screen are obtained respectively.

[0019] In this step, the user can write on the secondary touchscreen, and the original touch point coordinate data of the writing content on the secondary touchscreen will be transmitted to the main touchscreen. For example, if the whiteboard software is running on the main touchscreen, the original touch point coordinate data of the first and second touch writing content on the primary and secondary touchscreens will be transmitted to the whiteboard software on the main touchscreen respectively.

[0020] S20, convert the original touch point coordinate data into main touch screen coordinate data on the main touch screen, and calculate the drawing coordinates of the main touch screen coordinate data corresponding to the rendering area set in the whiteboard software interface.

[0021] In this step, the whiteboard software maps the original touch point coordinate data on the secondary touchscreen to the primary touchscreen and converts it into primary touchscreen coordinate data. At the same time, based on the received original coordinate data and the data source from different touchscreens (i.e., whether it comes from the first or second touchscreen), the whiteboard software determines the rendering area of ​​the touch writing content on the secondary touchscreen on the whiteboard software interface, and then calculates the drawing coordinates on the rendering area of ​​the whiteboard software interface corresponding to the primary touchscreen coordinate data.

[0022] In some embodiments, such as Figure 3 As shown, Figure 3 This is a schematic diagram of the rendering area of ​​a whiteboard software interface; as shown in rendering area ①, the rendering area for the first touch writing content is the area between the upper left corner and the lower right corner of the center line of the whiteboard software interface; as shown in rendering area ②, the rendering area for the second touch writing content is the area between the upper right corner and the center line of the whiteboard software interface; the dotted line in the middle of the figure is the center line.

[0023] Due to the difference in coordinate systems, coordinate system transformation is required. First, based on the screen resolution of the secondary touchscreen (i.e., its length and width), select the rendering area with the corresponding aspect ratio in the whiteboard software interface, and then combine... Figure 3As shown, the origin can be set as the reference point. For example, rendering area ① takes the upper left corner of the whiteboard software as the origin, corresponding to the upper left corner of the first touch screen, and the lower left corner of the whiteboard software interface corresponds to the lower right corner of the first touch screen; rendering area ② takes the upper right corner of the center line of the whiteboard software interface as the origin, corresponding to the upper left corner of the second touch screen, and the lower right corner of the whiteboard software interface corresponds to the lower right corner of the second touch screen.

[0024] S30, draw the touch writing content in the set rendering area according to the drawing coordinates, and record the corresponding drawing screen and erasure information in real time.

[0025] Specifically, based on the real-time calculated drawing coordinates, the corresponding touch-written content is drawn in the designated rendering area; for example... Figure 3 As shown, the first touch writing content A can be drawn in area ① of the whiteboard software interface, and the second touch writing content B can be drawn in area ② of the whiteboard software interface; at the same time, the whiteboard software records the corresponding drawing screen and erasure information in real time; in addition, if the main touch screen needs to use the whiteboard software to write, its corresponding rendering area is the range from the upper left corner to the lower right corner of the whiteboard software.

[0026] During this process, users can perform multiple writing, multiple erasing, or multiple simultaneous writing and erasing operations on the first and second touchscreens without affecting each other; all drawing and erasing information will be recorded in real time by the whiteboard software.

[0027] As described in the above embodiments, the solution can efficiently save the touch-written content on the secondary touchscreen of the all-in-one teaching blackboard, reduce the repetitive writing of the same content, and allow users to review the content written on the secondary touchscreen and its erasure information as needed, achieving a one-click save function. Multiple people's writing and erasure operations do not affect each other, making it convenient for users to review the saved content.

[0028] To make the technical solution of this application clearer, more embodiments are provided below.

[0029] In some embodiments, the method for processing touch-written content in this application may further include the following steps: In response to secondary editing operations input by the user through the whiteboard software, the touch writing content on the secondary touchscreen can be edited or shared.

[0030] Specifically, such as Figure 4 As shown, Figure 4This is a sample whiteboard software interface diagram. A secondary editing button can be set on the whiteboard software interface, as shown by the word "Edit". When it is necessary to edit the saved touch writing content on the secondary touch screen again, the user can trigger the secondary editing button, and the whiteboard software will recall the saved whiteboard content. The user can then edit and save the corresponding whiteboard content again through the whiteboard software interface.

[0031] As described in the above embodiments, the secondary editing operation design allows users to further edit and apply the saved whiteboard content, thereby improving the usability and user experience.

[0032] In some embodiments of the touch writing method of this application, the following steps may also be included: In response to the user's operation on the preset switching button control on the whiteboard software interface on the main touch screen, the whiteboard software interface is switched between large screen mode and small window mode; wherein, in the large screen mode, the whiteboard software interface is displayed in full screen, and in the small window mode, the whiteboard software interface is shrunk according to a set ratio.

[0033] Specifically, such as Figure 5 As shown, Figure 5 This is another example of a whiteboard software interface diagram; a toggle button control can be set on the whiteboard software interface. When it is necessary to switch between large screen mode and small window mode, the user can trigger the toggle button control to switch. In large screen mode, the whiteboard software can occupy the entire screen of the main touch screen, thereby maximizing the use of the main touch screen to display the whiteboard content of the secondary touch screen. At the same time, when it is necessary to use the main touch screen, it can be switched to small window mode to minimize the impact on the use of the main touch screen.

[0034] As in the above embodiments, the solution allows for the selection and application of functions to meet different needs by switching between large screen mode and small window mode.

[0035] In some embodiments, the method for processing touch-written content in this application may further include the following steps: In the small window mode, the whiteboard software interface window is displayed on the upper layer of the main touch screen, and the whiteboard software interface window is dragged in response to the user's touch drag operation.

[0036] For example, such as Figure 6 As shown, Figure 6This is another example of a whiteboard software interface diagram. In small window mode, the main touchscreen can be used to play courseware or teaching videos. The whiteboard software interface window is displayed in a small window on top of the main touchscreen. In teaching scenarios, the small window mode allows teachers to select commonly used teaching tools according to their original teaching habits, reducing the learning cost. At the same time, teachers can use touch operations on the main touchscreen to drag the whiteboard software window, thus not affecting the teaching application of the main touchscreen and improving the user experience.

[0037] In some embodiments, the method for processing touch-written content in this application may further include the following steps: In the large screen mode, in response to the user's operation of the preset swap button control, the positions of the first touch writing content and the second touch writing content rendered on the whiteboard software interface are swapped.

[0038] Specifically, such as Figure 7 As shown, Figure 7 This is another example of a whiteboard software interface diagram. A "swap" button is provided. When the user triggers the swap button, the first touch writing content A in rendering area ① and the second touch writing content B in rendering area ② are swapped. Taking a teaching scenario as an example, when writing on a traditional blackboard, students sitting in the front right row may have difficulty seeing the left side of the blackboard due to glare, and similarly, students sitting in the front left row may have difficulty seeing the right side. Therefore, by swapping the touch writing content of the first and second touchscreens on the main touchscreen in a large-screen mode, students in the front right row can clearly see the left side of the blackboard, and similarly, students in the front left row can clearly see the right side of the blackboard.

[0039] The solution described in the above embodiment solves the problem that when writing on a traditional blackboard, students sitting in the front right row cannot see the content written on the left side of the board due to blackboard glare, and students sitting in the front left row cannot see the content written on the right side of the board due to blackboard glare, thus greatly improving the user experience.

[0040] The following describes embodiments of the touch writing content processing device of this application, with reference to... Figure 8 , Figure 8 This is a schematic diagram of a touch writing content processing device according to one embodiment; the touch writing content processing device is applied to an all-in-one teaching blackboard, the all-in-one teaching blackboard includes a main touch screen and secondary touch screens located on both sides of the main touch screen, the device includes: The writing content acquisition module 10 is used to acquire the original touch point coordinate data of the touch writing content of the secondary touch screen based on the whiteboard software running on the main touch screen. Touch coordinate conversion module 20 is used to convert the original touch point coordinate data into main touch screen coordinate data on the main touch screen, and calculate the drawing coordinates of the main touch screen coordinate data corresponding to the rendering area set in the whiteboard software interface. The drawing and erasure recording module 30 is used to draw the touch writing content in the set rendering area according to the drawing coordinates, and to record the corresponding drawing screen and erasure information in real time.

[0041] The touch writing content processing device of this embodiment can execute a touch writing content processing method provided in the embodiments of this application. The implementation principle is similar. The actions performed by each module in the touch writing content processing device in each embodiment of this application correspond to the steps in the touch writing content processing method in each embodiment of this application. For detailed functional descriptions of each module of the touch writing content processing device, please refer to the descriptions in the corresponding touch writing content processing methods shown above. They will not be repeated here.

[0042] The following describes an example of an all-in-one teaching blackboard.

[0043] like Figure 9 As shown, Figure 9 This is a schematic diagram of an all-in-one teaching blackboard structure according to an embodiment of this application, which includes: a main touch screen and secondary touch screens located on both sides of the main touch screen; the secondary touch screens are provided with touch frame devices; wherein, the touch frame devices are used to detect touch positioning data and send it to the main touch screen; The main touchscreen is configured to execute the touch writing content processing method of any of the foregoing embodiments to process the touch writing content of the secondary touchscreen.

[0044] For example, the touch frame device and the main touch screen can be connected via USB wired connection or other connection methods; the secondary touch screen may include a first touch screen and a second touch screen, and the first touch screen and the second touch screen are respectively provided with touch frame devices, which are used to detect touch positioning data and send it to the main touch screen.

[0045] The all-in-one teaching blackboard of this application acquires the first touch writing content of the first touch screen and the second touch writing content of the second touch screen based on the whiteboard software running on the main touch screen. It converts the original touch point coordinate data of the first touch writing content and the second touch writing content into the drawing coordinates of the whiteboard software, and renders them in a specified rendering area on the whiteboard software interface. Then, it records the drawing and erasing information of the touch writing content of the first touch screen and the second touch screen in real time based on the whiteboard software. It can realize the efficient saving of the blackboard content of the secondary touch screen of the all-in-one teaching blackboard, reduce the repeated writing of the same blackboard content, and facilitate users to review the saved blackboard content.

[0046] Furthermore, users can edit or share the handwritten content on the secondary touchscreen through secondary editing operations input by the whiteboard software; this allows users to further edit and apply the saved whiteboard content, thereby improving the usability and user experience.

[0047] Furthermore, users can operate the preset switching button controls on the whiteboard software interface via the main touchscreen to switch between large screen mode and small window mode, thus enabling different function selections and applications to meet different needs.

[0048] Furthermore, in the small window mode, the whiteboard software interface window is displayed on the upper layer of the main touch screen, and users can touch and drag the whiteboard software interface window. In teaching scenarios, the small window mode allows teachers to select commonly used teaching tools according to their original teaching habits, reducing the learning cost. At the same time, teachers can use touch operations on the main touch screen to manipulate the whiteboard software window and drag it, thus not affecting the teaching application of the main touch screen and improving the user experience.

[0049] Furthermore, in large-screen mode, users can perform operations on preset swap button controls to swap the positions of the first and second touch writing content rendered on the whiteboard software interface. This solves the problem that when writing on a traditional blackboard, students sitting in the front right row cannot see the writing on the left side of the board due to blackboard glare, and students sitting in the front left row cannot see the writing on the right side of the board due to blackboard glare, greatly improving the user experience.

For example, a non-transitory computer-readable storage medium can be a ROM, random access memory (RAM), CD-ROM, magnetic tape, floppy disk, and optical data storage device, etc.

[0053] The above description is only a partial embodiment of this application.
