[0009] To describe in detail the technical content, the achieved purpose and the effects of the present invention, the following is described in conjunction with the embodiments and with reference to the drawings.

[0010] Please refer to Figure 1 , a method for adjusting the content of a large-screen presentation, includes the following steps: S1. Receive a touch-screen operation instruction on the large screen, and generate a small window corresponding to the touch-screen operation instruction on the real-time display screen of the large screen through the window generation module carried by the large screen; S2. While the real-time display screen of the large screen continues to play, display the preview content corresponding to the played content of the real-time display screen and the adjustment items corresponding to the preview content on the small window.

[0011] As can be seen from the above description, the beneficial effects of the present invention are as follows: after receiving the touch screen operation instruction of the operator, the window generation module built in the large screen generates a small window on the real-time display screen, uses the small window to display the preview content corresponding to the current playback content, and can adjust the preview content. The touch screen control and the window generation module cooperate with each other, without the need to rely on external devices for small window generation operations, and while adjusting the preview content, it does not affect the real-time playback content, avoiding interruption and incoherence to the content displayed on the screen and the operation content explained by the operator from both the artificial operation method and the realization of device functions, helping the operator to view, preview and set the display content more conveniently, and improving the efficiency and effect of the display.

[0012] Further, before the step S1, it further includes: S0. Create a window configuration list corresponding to the small window, obtain the configuration result of the operator in the window configuration list, and send the configuration result to the window generation module.

[0013] As can be seen from the above description, by providing a window configuration list to the operator, the customization of the small window style is realized, meeting the actual use needs of the operator, making the small window function highly flexible and practical.

[0014] Further, the step S1 further includes: Parse the set of touch points of the operator on the large screen according to the touch screen operation instruction, generate a window generation instruction according to the set of touch points, and send the window generation instruction to the window generation module.

[0015] As can be seen from the above description, when generating a small window, a window generation instruction is generated based on the set of touch points of the operator, so that the position of the window is associated with the position of the touch points, improving the freedom and convenience of the operator to call the small window.

[0016] Further, the generating the window generation instruction according to the set of touch points specifically is: Determine the center point and the boundary points of the small window according to the coordinates of each touch point in the set of touch points; Determine the size and brightness of the small window according to all the boundary points; Integrate the center point, the boundary points, the size and the brightness to obtain the window generation instruction.

[0017] As can be seen from the above description, when the operator touches the large screen, the position and size of the small window can be controlled according to the touched points, and the window boundary can also be adjusted based on the touch, making the generation operation convenient and flexible enough, and reducing the impact on the fluency of the operator's explanation of the playback content.

[0018] Further, after the step S2, the following steps are further included: S3. Obtain the push content and display the push content on the small window.

[0019] As can be seen from the above description, the small window can be used to display the push content, helping the operator to perform switching control on the current playback content with reference to the push content, flexibly adjust the displayed content, and improve the viewing experience of the audience.

[0020] Please refer to Figure 2 and Figure 3 , a large-screen presentation content adjustment system, including a memory, a processor, and a computer program stored on the memory and executable on the processor. When the processor executes the computer program, the following steps are implemented: S1. Receive a touch screen operation instruction on the large screen, and generate a small window corresponding to the touch screen operation instruction on the real-time display screen of the large screen through a window generation module carried by the large screen; S2. While continuously playing the real-time display screen of the large screen, display the preview content corresponding to the playback content of the real-time display screen and the adjustment items corresponding to the preview content on the small window.

[0021] As can be seen from the above description, the beneficial effects of the present invention are as follows: After receiving the touch screen operation instruction of the operator, a small window is generated on the real-time display screen by the window generation module built in the large screen. The small window is used to display the preview content corresponding to the current playback content and can adjust the preview content. The touch screen control and the window generation module cooperate with each other, and there is no need to rely on external devices to generate the small window operation. At the same time, when adjusting the preview content, it does not affect the real-time playback content. From the aspects of the manual operation method and the realization of the device function, it avoids interrupting and making the screen display content and the operator's explanation of the operation content discontinuous, helping the operator to view, preview and set the display content more conveniently, and improving the efficiency and effect of the display.

[0022] Further, before the step S1, the following steps are further included: S0. Create a window configuration list corresponding to the small window, obtain the configuration result of the operator in the window configuration list, and send the configuration result to the window generation module.

[0023] As can be seen from the above description, by providing the window configuration list to the operator, the customization of the small window style is realized, meeting the actual use needs of the operator, making the small window function highly flexible and practical.

[0024] Further, the step S1 further includes: Analyze the set of touch points of the operator on the large screen according to the touch screen operation instruction, generate a window generation instruction according to the set of touch points, and send the window generation instruction to the window generation module.

[0025] As can be seen from the above description, when generating a small window, a window generation instruction is generated based on the set of touch points of the operator, so that the window position is linked to the position of the touch points, improving the freedom and convenience for the operator to call the small window.

[0026] Further, the generating the window generation instruction according to the set of touch points is specifically: Determine the center point position and the boundary point positions of the small window according to the coordinates of each touch point in the set of touch points; Determine the size and brightness of the small window according to all the boundary point positions; Integrate the center point position, the boundary point positions, the size, and the brightness to obtain the window generation instruction.

[0027] As can be seen from the above description, when the operator touches the large screen, the position and size of the small window can be controlled according to the touched points, and the window boundary can also be adjusted based on the touch, making the generation operation sufficiently convenient and flexible, and reducing the impact on the fluency of explaining the projection content to the operator.

[0028] Further, after the step S2, it further includes: S3. Obtain the pushed content and display the pushed content on the small window.

[0029] As can be seen from the above description, the small window can be used to display the pushed content, helping the operator to switch and control the current projection content with reference to the pushed content, flexibly adjust the displayed content, and enhance the viewing experience of the audience.

[0030] Please refer to Figure 1 , the first embodiment of the present invention is: A method for adjusting the presentation content on a large screen, including the following steps: S0. Create a window configuration list corresponding to the small window, obtain the configuration result of the operator in the window configuration list, and send the configuration result to the window generation module.

[0031] Among them, the window configuration list may include memory allocation for small windows, UI layout, function module loading, event binding, etc.; among them, function module loading such as recently played content, content preview, push settings, etc.; event binding means binding each function module of the small window to the corresponding touch event to ensure that the operations of the user within the small window can be correctly processed. Send the configuration result to the window generation module to complete the initialization of the small window. The window generation module is responsible for rendering the small window onto the large screen and ensuring that the small window can respond to the touch operations of the user. The window generation module is also responsible for managing the hierarchical relationship of the small window to ensure that the small window is displayed above other content and can be closed or hidden when needed. Through the above internal logic, after receiving the touch screen operation instruction of the user, a small window is created on the large screen without relying on other external devices.

[0032] S1. Receive the touch screen operation instruction on the large screen, and generate a small window corresponding to the touch screen operation instruction on the real-time display screen of the large screen through the window generation module carried by the large screen; In this embodiment, first check whether there is already a small window on the current large screen. If not, continue with the creation process; if it already exists, ignore the new creation request or update it as needed.

[0033] When generating, parse the set of touch points on the large screen according to the touch screen operation instruction, generate a window generation instruction according to the set of touch points, and send the window generation instruction to the window generation module. Generating a window generation instruction according to the set of touch points specifically means: determining the center point position and boundary point positions of the small window according to the coordinates of each touch point in the set of touch points; determining the size and brightness of the small window according to all the boundary point positions; integrating the center point position, boundary point positions, size, and brightness to obtain the window generation instruction. Taking five-finger touch as an example, in the touch operation where the user touches five fingers twice, the touch detection module will capture the coordinates of each touch point to obtain a set of touch points. Assuming the coordinates of the five touch points are , then the following process is included: First, determine the center position of the small window by calculating the average position of the five touch points, and the center point The calculation formula is: ; ; Secondly, in order to determine the size of the small window, the bounding rectangle of the five touch points can be calculated, and the upper left corner and the lower right corner of the bounding rectangle have the following coordinates: ; ; ; ; Then, determine the width and height of the small window according to the size of the bounding rectangle. The calculation formulas for the width and height of the small window are as follows: ; Finally, the upper-left corner position and the lower-right corner position of the small window can be calculated based on the center point and the width and height of the small window: ; ; Transfer the calculated position and size to the window generation module, and the window generation module renders the small window on the large screen according to these parameters.

[0034] S2. While the real-time display screen on the large screen is continuously playing, display the preview content corresponding to the content being played on the real-time display screen and the adjustment items for the corresponding preview content on the small window.

[0035] In this embodiment, the adjustment items for the corresponding preview content include, but are not limited to, adjusting the picture parameters such as brightness and contrast of the preview content to be played on the large screen, as well as adding, deleting, and adjusting the order of the content, etc. When the operator wants to immediately use the content on the small window as the main content to be played on the large screen, it can be achieved by pressing the switch button; during this process, the large screen is continuously in the working state of demonstrating the content to be played.

[0036] Moreover, the small window provides a variety of layout forms, and teachers can choose different display methods such as four-grid pictures and left-right split screens according to the teaching content. This not only improves the display effect of the teaching content but also enhances the learning experience of students.

[0037] S3. Obtain the pushed content and display the pushed content on the small window.

[0038] In this embodiment, the large screen is equipped with a content push module by default, and users can select the content push method through this module, including immediate push and scheduled push. The immediate push function allows users to push content to the small window on the large screen at any time, while the scheduled push function supports automatic push at a preset time.

[0039] Based on this embodiment, taking classroom teaching as an example, the teacher only needs to tap the large screen twice with five fingers at the same time to bring up the setting window. In this window, the teacher can view the content played recently, preview the content to be played next, and make corresponding settings. For example, the teacher can select the courseware that needs to be pushed immediately, or preset the content to be pushed at a certain time to ensure the coherence and interactivity of the teaching process.

[0040] Taking a museum or other exhibition hall as an example, the staff can use the system of the present invention to flexibly control the display content. For example, during the explanation process, the staff can bring up the setting window through touch operations, view the recently played exhibit introductions, and preview the content to be displayed next. Through the immediate push and scheduled push functions, the staff can flexibly adjust the display content according to the interests and feedback of the audience, enhancing the viewing experience of the audience.

[0041] Please refer to Figure 2 and Figure 3 , Embodiment 2 of the present invention is as follows: A large-screen presentation content adjustment system 1 includes a memory 2, a processor 3, and a computer program stored on the memory 2 and executable on the processor 3. When the processor 3 executes the computer program, it implements a large-screen presentation content adjustment method according to Embodiment 1.

[0042] Corresponding to a large-screen presentation content adjustment method according to Embodiment 1, a large-screen presentation content adjustment system of the present application has function modules as shown in Figure 2 . Among them, the large-screen touch screen module is used to set the touch control method and identify and receive touch operation instructions on the large screen; the window generation module is used to generate a small window; the content push module performs content push according to the set push method; the content preview module provides preview content in the small window and adjustment items corresponding to the preview content; the layout setting module is used to adjust the layout method of the small window.

[0043] In summary, a method and system for adjusting the content of a large-screen presentation provided by the present invention, after receiving a touch operation instruction from an operator, a window generation module built into the large screen generates a small window on the real-time display screen, uses the small window to display the preview content corresponding to the currently played content, and can adjust the preview content. The touch control and the window generation module cooperate with each other, without the need to rely on external devices for small window generation operations, and while adjusting the preview content, it does not affect the real-time played content, avoiding interruption and incoherence to the screen display content and the operator's explanation and operation content from two aspects of the manual operation method and the realization of device functions, helping the operator to view, preview and set the display content more conveniently, improving the efficiency and effect of the display; at the same time, push content can be displayed on the small window, with different push methods such as instant push and timed push, helping the operator to flexibly adjust the display content and enhancing the viewing experience of the audience.
