DETAILED DESCRIPTION

[0010] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application may also be implemented in other embodiments without these specific details.

[0011] In order to illustrate the technical solution described in this application, a specific embodiment is provided below for illustration.

[0012] Figure 1 A display screen projection control method provided in the first embodiment of the present application is shown, which is applied to a display screen. The display screen projection control method includes: S1: when receiving a projection signal from the projection end, identifying whether the first page currently displayed on the projection end is a software page, and if so, displaying the software page on the display screen; S2: If the first page is not a software page, query the built-in software information of the projection end, wherein the built-in software information includes software icons of all built-in software of the projection end; S3: after receiving the built-in software information sent by the projection end, a software bar is generated on the display screen, and each received software icon is placed in the software bar; S4: When it is recognized that the user clicks on any software icon in the software bar, the software icon is sent to the projection end, so that the projection end determines the software to be started and starts the software; S5: Displaying the started software page on the display screen; S6: Determine the operation of the user on the software page on the display screen, determine the equivalent operation corresponding to the operation on the projection end, control the projection end to execute the software response action corresponding to the equivalent operation according to the equivalent operation, and display the software response action accordingly on the software page on the display screen; S7: Execute steps S6 to S7 until the user completes the software operation and removes the software page from the display screen; S8: Repeat steps S4 to S7 until a signal from the user to end screen projection is received.

[0013] In this embodiment, if Figure 2 As shown, the method is executed in a display screen (such as a large LCD TV), and the display screen can communicate with a projection end (an electronic device that sends the projection), which can be a mobile phone, a tablet computer, a laptop computer, a desktop computer, etc., and is not limited here; after the projection end projects the screen on the display screen, the display screen can interact with the projection end for information, thereby realizing the function of the method.

[0014] In this embodiment, when the user performs screen projection, he often displays the content of a certain software running on the projection end, such as PPT, video software or other software; therefore, when a certain software page has been opened on the projection end, the software page can be directly displayed; if no software is opened, due to the limitation of the screen size of some projection ends, the software is often arranged in multiple pages (such as mobile phones), and it is necessary to repeatedly search when opening the software. In this embodiment, all the software of the projection end can be placed in it by generating a software column (the arrangement and order are consistent with those in the projection end), so that the user can directly view all the built-in software of the projection end on the display screen, and then quickly find the software to be started without too much searching, thereby improving the user's opening speed. The efficiency of opening software is improved; after the user finds the software to be opened, he can directly click the icon on the display screen. The display screen can determine which software icon the user clicked according to the coordinate position of the click and the coordinate position of the icon, and then send the determined software icon information to the projection end to enable the projection end to start the software; after the software page is displayed on the display screen, the software bar is hidden. When the software page is displayed, a virtual button for removing the software page is generated on the display screen. The user can remove the software page by clicking the virtual button, and then redisplay the software bar, so that the user can open other software. This cycle repeats until the user clicks the end projection button on the display screen, or sends a signal to end projection to the display screen through the projection end, so that the projection ends.

[0015] In this embodiment, since the software being launched is installed on the projection end, the user cannot directly control the software through the display screen. This method creatively applies the operation equivalent conversion method to equate the user's operation on the display screen to the projection end, so that the projection end can execute the corresponding software response action, thereby allowing the user to directly control the software installed on the projection end on the display screen, so that the user does not need to operate the projection end and the display screen at the same time, which greatly improves the convenience of the user's projection demonstration.

[0016] As a preferred embodiment, determining the operation of the user on the software page on the display screen, determining the equivalent operation corresponding to the operation on the projection end, controlling the projection end to perform the software response action corresponding to the equivalent operation according to the equivalent operation, and correspondingly displaying the software response action on the software page on the display screen includes: After each time it is detected that a software page on the display screen is pressed, a first pressing position is identified on the display screen; Determine an equivalent pressing position of the first pressing position on the projection end screen; The equivalent pressing position is sent to the projection end, so that the projection end determines the action instruction when the equivalent pressing position is pressed on the current display page, and executes the corresponding software response action according to the action instruction; Monitor the page changes of the projection end when executing software response actions, and control the display screen to display the page changes of the projection end on the software page.

[0017] In this embodiment, the user's operations on the display screen can be regarded as pressing (wherein, the user's sliding operation on the display screen can be regarded as continuously pressing multiple adjacent points), and the user's operation on the software page on the display screen is determined, that is, the pressing position of the user on the display screen each time is determined, and the equivalent operation is determined, that is, the equivalent pressing position is determined; after the projection end receives the equivalent pressing position, it is equivalent to receiving a pressing operation at that position, and thus executes a corresponding response action; when the projection end executes the response action, the content displayed on its screen will change accordingly (that is, the page changes). Since the display screen and the projection end are mirrored, when the screen of the projection end changes page, the software page on the display screen also changes accordingly.

[0018] like Figure 3 As shown, as a preferred embodiment, the shape of the software page on the display screen is proportional to the shape of the screen on the projection end; the screen coordinate system of the display screen is used as the first coordinate system, and whenever the display screen is pressed, the display screen can identify the coordinates of the pressed position on the first coordinate system, that is, the first coordinates; Determining the equivalent pressing position of the first pressing position on the projection end screen includes: A second coordinate system is generated with the upper left corner of the software page on the display screen as the origin, wherein the second coordinate system is an equivalent coordinate system of the screen coordinate system of the projection end, and two coordinate axes of the second coordinate system coincide with two adjacent edges intersecting at the upper left corner of the software page; Identify the horizontal coordinate of the origin of the second coordinate system in the first coordinate system , vertical coordinate And the rotation angle of the second coordinate system relative to the first coordinate system ; Determine the scale of the abscissa of the second coordinate system relative to the abscissa of the first coordinate system , and the scaling ratio of the ordinate of the second coordinate system relative to the ordinate of the first coordinate system ; Each time a first coordinate is identified, according to the determined , , as well as The second coordinate of the first coordinate in the second coordinate system, ie, the equivalent pressing position, is calculated.

[0019] The second coordinate of the first coordinate in the second coordinate system is calculated by the following formula: in, is the horizontal coordinate of the first coordinate, is the ordinate of the first coordinate, is the horizontal coordinate of the second coordinate, is the ordinate of the second coordinate.

[0020] In this embodiment, both the display screen and the projection screen have built-in screen coordinate systems. The screen coordinate system is a two-dimensional coordinate system for determining the position of a point on the screen. In this coordinate system, the upper left corner of the screen is usually used as the origin (0, 0), the horizontal rightward direction is the positive direction of the X axis, and the vertical downward direction is the positive direction of the Y axis; the shape of the software page on the display screen is proportional to the shape of the projection screen, that is, the length ratio and width ratio of the two shapes are consistent; the scaling ratio is the ratio of the coordinate values ​​in the two coordinate systems corresponding to the same distance in the two coordinate systems. and The same as the length ratio / width ratio mentioned above, for example, if the length ratio is 0.1, then = =0.1; Under normal circumstances is 0, but when the user needs to take care of some viewers and needs to rotate the software page on the display screen, the second coordinate system rotates accordingly, making Corresponding changes occur; in this embodiment, since the display screen can only monitor the first coordinate of the pressed position in its own screen coordinate system (i.e., the first coordinate system), the conversion method of this embodiment can directly convert the monitored first coordinate into its second coordinate on the projection screen, thereby accurately realizing the determination of equivalent operations.

[0021] As a preferred embodiment, the software corresponding to the software page on the display screen is used as the target software; during the process of executing step S7, it also includes: Query the tasks being performed by the target software on the screen projection end; After receiving the task being executed by the target software replied by the projection end, determine whether the task is a splittable task; If yes, determine whether there is matching software in the built-in software of the display screen that can perform the task; If so, the matching software is mobilized to assist the target software in completing the task.

[0022] Mobilizing the matching software to assist the target software in completing the task includes: Query the projection end for the total number of tasks and the remaining number of tasks for the task; When receiving the total amount of tasks and the remaining amount of tasks, determining a first efficiency of the target software in completing the tasks; Determine the second efficiency of the matching software to complete the task based on historical data; The remaining task volume is split according to the first efficiency and the second efficiency, so as to obtain a first partial task assigned to the target software and a second partial task assigned to the matching software; Send split information to the projection end, so that the projection end returns the input information of the second partial task and executes the second partial task according to the input information; The execution result of the second partial task is transmitted back to the projection end, so that the projection end merges the execution result of the first partial task with the execution result of the second partial task, thereby obtaining the execution result of the task.

[0023] Determine the first efficiency of the target software to complete the task including: Subtract the remaining task amount from the total task amount to get the completed task amount; Determine the first duration from the time when the task is started to the current time; Divide the amount of completed tasks by the first duration to get the first efficiency; The second efficiency of matching software to complete this task based on historical data includes: Retrieving task execution information of each time the matching software executes a historical task that is the same as the task, wherein the task execution information includes the task amount of the historical task and the second duration of the matching software executing the historical task; For each historical task, the task amount of the historical task is divided by the corresponding second duration to obtain the execution efficiency of the historical task; Find the average of the execution efficiency of each historical task and get the second efficiency.

[0024] The remaining task volume is split according to the first efficiency and the second efficiency, so as to obtain the first partial task assigned to the target software and the second partial task assigned to the matching software, including: Add the first efficiency and the second efficiency to get the total efficiency; Divide the first efficiency by the total efficiency to obtain the first efficiency ratio; Multiply the remaining task volume by the first efficiency ratio to obtain the first task volume; A partial task of the first task amount is divided out from the remaining task amount, namely, a first partial task, and the partial task corresponding to the remaining task amount is used as a second partial task.

[0025] In this embodiment, a task database is preset in the display screen, which includes all splittable tasks, such as "extracting text from a PDF file", and non-divisible tasks, such as "video playback". After obtaining the task being executed by the projection end, the display screen can compare the task with the task in the task database to determine whether it can be split; In this embodiment, for example, for the task of 'extracting text from a PDF file', since the text extraction is performed on each page of the PDF one by one, the pages of the PDF can be split and then assigned to two software for execution; the remaining pages of the PDF that have not been extracted are the remaining task volume, and the corresponding proportion of pages are divided from the remaining pages according to the first efficiency ratio. The first local task is to extract text from the divided PDF pages. Similarly, the text extraction from another part of the remaining PDF pages is the second local task; the completion of each task requires the input information to be imported into the software, and the execution result will be generated after the software is executed. Taking PDF text extraction as an example, the input information is the page of the PDF, and the execution result is the extracted text; furthermore, the display screen can store historical task information in the cloud and call it when needed; in this embodiment, if the task can be split, the remaining tasks can be split and allocated according to the execution efficiency (the amount of tasks completed per unit time) of the target software and the matching software (the higher the execution efficiency, the more tasks are allocated), so that the target software and the matching software can complete the assigned local tasks at about the same time, thereby enabling the task to be completed as quickly as possible.
