Fig. 4 illustrates a software configuration diagram in the display device 200 according to some embodiments. Referring to fig. 4, in some embodiments, the system is divided into four layers, which are an Application (Applications) layer (abbreviated as "Application layer"), an Application Framework (Application Framework) layer (abbreviated as "Framework layer"), an Android runtime (Android runtime) and system library layer (abbreviated as "system runtime library layer"), and a kernel layer from top to bottom.

In some embodiments, at least one application program runs in the application program layer, and the application programs may be windows (windows) programs carried by an operating system, system setting programs, clock programs or the like; or may be an application developed by a third party developer. In particular implementations, the application packages in the application layer are not limited to the above examples.

The framework layer provides an Application Programming Interface (API) and a programming framework for the application. The application framework layer includes a number of predefined functions. The application framework layer acts as a processing center that decides to let the applications in the application layer act. The application program can access the resources in the system and obtain the services of the system in execution through the API interface.

FIG. 5 illustrates an icon control interface display of an application in display device 200, according to some embodiments. In some embodiments, the display device may directly enter the interface of the preset vod program after being activated, and the interface of the vod program may include at least a navigation bar 510 and a content display area located below the navigation bar 510, as shown in fig. 5, where the content displayed in the content display area may change according to the change of the selected control in the navigation bar. The programs in the application program layer can be integrated in the video-on-demand program and displayed through one control of the navigation bar, and can also be further displayed after the application control in the navigation bar is selected.

In some embodiments, the display device may directly enter a display interface of a signal source selected last time after being started, or a signal source selection interface, where the signal source may be a preset video-on-demand program, or may be at least one of an HDMI interface, a live tv interface, and the like, and after a user selects different signal sources, the display may display contents obtained from different signal sources.

Based on the display device 200 described above, the display device 200 may be enabled to support a touch interaction function by adding the touch component 276. In general, the touch-sensitive component 276 may constitute a touch screen with the display 260. A user can input different control instructions on the touch screen through touch operation. For example, the user may input a click, slide, long press, double click, etc. touch command, and different touch commands may represent different control functions.

To implement the different touch motions, the touch control component 276 may generate different electrical signals when a user inputs different touch motions and transmit the generated electrical signals to the controller 250. The controller 250 may perform feature extraction on the received electrical signal to determine a control function to be performed by the user based on the extracted features.

For example, when a user enters a click touch action at any program icon location in the application interface, the touch component 276 will sense the touch action and generate an electrical signal. After receiving the electrical signal, the controller 250 may first determine a duration of a level corresponding to a touch action in the electrical signal, and when the duration is less than a preset time threshold, recognize that a click touch instruction is input by the user. The controller 250 extracts the position characteristics generated by the electrical signals to determine the touch position. And when the touch position is within the display range of the application icon, determining that the user inputs a click touch instruction at the position of the application icon. Accordingly, the click touch command is used to execute a function of running a corresponding application program in the current scene, so that the controller 250 may start running the corresponding application program.

For another example, when the user enters a swipe action in the media presentation page, the touch-sensitive component 276 also sends the sensed electrical signal to the controller 250. The controller 250 first determines the duration of the signal corresponding to the touch action in the electrical signal. When the determined duration is longer than the preset time threshold, the position change condition generated by the signal is judged, and obviously, for the interactive touch action, the generation position of the signal changes, so that the sliding touch instruction input by the user is determined. The controller 250 determines the sliding direction of the sliding touch instruction according to the change condition of the position of the signal generation, and controls to turn pages of the display frame in the media asset display page so as to display more media asset options. Further, the controller 250 may extract features such as a sliding speed and a sliding distance of the sliding touch instruction, and perform a page-turning screen control according to the extracted features, so as to achieve a hand-following effect.

Similarly, for the touch instruction such as double click, long press, etc., the controller 250 may execute the corresponding control function according to the preset interaction rule by extracting different features and determining the type of the touch instruction through feature judgment. In some embodiments, the touch component 276 also supports multi-touch, such that a user can input touch actions on the touch screen with multiple fingers, e.g., multi-finger clicks, multi-finger long presses, multi-finger swipes, and the like.

The touch control action can be matched with a specific application program to realize a specific function. For example, when the user opens the "demonstration whiteboard" application, the display 260 may present a drawing area, the user may draw a specific touch trajectory in the drawing area through the sliding touch command, and the controller 250 determines a touch pattern through the touch detected by the touch component 276 and controls the display 260 to display in real time to satisfy the demonstration effect.

The display of the Touch Screen display device is a Touch Screen display (Touch Screen), and the Touch Screen display can enable a user to operate the host machine only by lightly touching the display with fingers, so that the operation of a keyboard, a mouse and a remote controller is avoided, and the man-machine interaction is more direct.

For example, a user is a basic function of a touch screen display device by rotating a finger touching a display to control the display to display a picture. The current interaction mode is that after the multiple fingers rotate on the screen, the picture immediately rotates to a horizontal or vertical angle according to the finger rotation direction, no interaction process exists, and user experience is poor.

In some embodiments, different applications may be configured in the display device to enable the display device to provide different functions to enrich the user experience. For example, different programs may be configured in the display device, so as to implement application scenarios such as online live lessons, teleconferencing, live game live broadcasting, electronic whiteboard sharing, and the like by using the display device.

When the display equipment is used for realizing the teaching live broadcast function, the program configured by the display equipment can be a live broadcast course program, and the display equipment configured with the live broadcast course program can be applied to any teaching mechanism, including schools, lesson supplementing mechanisms and the like. When the teaching live broadcast is carried out on the display equipment, the large-screen experience can be provided for the user, and more teaching contents and operation functions required in the teaching live broadcast process can be displayed by utilizing the display equipment.

In some embodiments, the live course program can be configured on a mobile phone end, a Pad end, a PC client, and the like, besides being applied to a display device end.

In some embodiments, the display device includes a display and a controller, the display is used for presenting a live teaching interface, and the controller is used for realizing live teaching according to live related operations. The live course program may be a "gather micro school" program. The live course program comprises a second program and a first program, the second program is a program configured in the teacher-side display device, and a second live interface is displayed in the display when the second program is started; the first program is a program configured in the student-side display device, and when the first program is started, the first direct-playing interface is displayed in the display.

Since the teacher and the student operate differently in some embodiments when the live class is in class, the second live interface and the first live interface have different display contents.

Fig. 6 illustrates a schematic diagram of a live lesson listing interface, according to some embodiments. Referring to fig. 6, a schematic view of a list interface of a student end live broadcast is shown. After the student end display equipment starts a first program, a live-broadcast class list interface is displayed in the student end display, and a date selection area and a live-broadcast class list of the student who finishes the class or is about to finish the class are presented in the live-broadcast class list interface. The date selection area is used for displaying dates, each date corresponds to a live-broadcast class list existing every day, each live-broadcast class in the live-broadcast class list corresponds to a live-broadcast class state, and the live-broadcast class states include but are not limited to a live-broadcast in-progress state (not shown in the figure), an upcoming live-broadcast state (not shown in the figure) and a watching-back state.

When a class is about to start, a button (not shown in the figure) about to live is correspondingly displayed on the right side of the corresponding live class; when the live course goes on, the right side of corresponding live course corresponds the button (not shown in the figure) in the display live, and the student clicks and is about to live button or live in the button, can get into in the live course.

Referring to fig. 7, after the teacher-side display device starts the second program, one of the live lessons that reaches the time of the lesson is clicked on the basis of the live lesson list, so that a second live interface is presented in the teacher-side display device. The second live broadcast interface displays a course content area, a student video area, a teacher video area, a main function area and a live broadcast information display area, and can realize three-screen split-screen lessons. The student video area is used for displaying student images, the teacher video area is used for displaying teacher images, and the student images and the teacher images are collected by a camera (such as an image collector in fig. 3) configured on the display device used by the student video area. The course content area displays a live broadcast picture, and the main function area is displayed below the course content area and used for switching functions of lectures, whiteboards, videos and the like. The live broadcast operation buttons and the battle team spelling condition are displayed below the main function area, and the live broadcast operation buttons comprise controls such as a handwriting input function (a button file is 'painting brush'), live broadcast starting (switching to pause live broadcast after starting), live broadcast ending and the like. To improve the lesson effect, the teacher can divide the students of the class into two teams, such as a tiger team and a waning team before live broadcasting, and the students of the teams can get corresponding rewards after the course is finished and the scores of the teams are high by answering questions and the like during the lesson. And displaying the scores of the two teams in real time according to the spelling condition of the teams.

And the handwriting input function control displayed on the second live broadcast interface is used for simulating a real class scene at a teacher end so as to realize the operation of writing and drawing on the live broadcast picture through handwriting input when arranging operation on a blackboard or marking the content of a certain writing course. For example, in the lecture function mode, a teacher end stylus or a finger or other touch manner may trigger a handwriting input function control, such as a "brush" control in fig. 7, in the live operation button, so as to perform interaction operations, such as drawing lines, writing, drawing, and the like, on the lecture displayed in the display by manually touching the display.

The live broadcast information display area in the second live broadcast interface is used for providing live broadcast information of a current live broadcast course, and comprises a discussion area, a student list and a drill. The forum is used for realizing real-time text (or voice) discussion and interaction between teachers and students and between students in a live class. The student list is used for displaying the number of the students who live in the class and the information of the students who live in the class. The on-line practice is used for realizing the on-line real-time question setting function of a teacher, when a live broadcast class is in class, the teacher can set and push the questions to a student end in real time through the on-line practice, and the student can answer the questions through a display device used by the student end.

FIG. 8 illustrates a schematic diagram of a first live interface, according to some embodiments. Referring to fig. 8, after the first program is started, the student-side display device clicks on one of the live lessons that reach the time of the lesson or the live lessons that are already in the live lesson based on the live lesson list to present a first live interface in the student-side display device. The first live-broadcasting interface is displayed with a course content area, a student video area, a teacher video area and a function area. The live broadcast picture of the course content area is consistent with the live broadcast picture of the course content area of the second live broadcast interface, the teacher video area is used for displaying teacher images, and the student video area is used for displaying student images. When a plurality of students are present in the live class, the student video area displays a plurality of student images.

In some embodiments, when displaying the student images and the teacher images, the student video area and the teacher video area are displayed above the course content area, the teacher video area is displayed in the first place, the student video area is located on the right side of the teacher video area, the images of the local students are located in the first place of the student video area, and the images of the rest of students are sequentially displayed in the order of entering the live lessons.

The functional area is used for realizing the interaction functions of students in the class of the live broadcast class, and comprises functional controls such as hand raising, handwriting input (selective configuration), discussion and help seeking. When a live class is in class, if students want to actively answer questions of teachers, the hands-raising function control can be triggered to inform the teachers that the students want to answer the questions. The handwriting input function control is used for performing corresponding handwriting input operations, such as adjusting a handwriting input pattern, painting, drawing and the like, according to the authorization of the teacher, wherein the handwriting input pattern comprises but is not limited to a brush pen shape, a color, a thickness, a font and the like. During scribbling, a student can scribble on the touch screen display through a touch pen used in cooperation with the display device, or can scribble on the touch screen display directly with a finger, the first direct-view interface shown in fig. 8 is a case where the handwriting input function is not configured, and the first direct-view interface shown in fig. 13 is a case where the handwriting input function is configured. The discussion control can realize real-time text discussion and interaction between teachers and students and between students, and can refer to discussion area functions in the second live broadcast interface. The help-seeking function control can provide a help-seeking function for the program platform under the conditions that a camera cannot be started, a live broadcast picture cannot be seen and the like when an application program is abnormal in a live broadcast class in a lesson.

FIG. 9 illustrates a schematic diagram of a lesson content area in a live interface when scribbling using handwritten input, in accordance with some embodiments. In some embodiments, referring to fig. 9, an online virtual interface formed by a live interface is used as a blackboard, and both a student and a teacher use respective handwriting input functions to perform scribbling operation on the corresponding live interface, wherein the live interface scribbled by the teacher is a second live interface, and the live interface scribbled by the student is a first live interface.

In some embodiments, when a student end or a teacher end can use a handwriting input function to perform a writing operation on a corresponding live interface, a display device used needs to be provided with a touch screen, and for a display device of a common screen, the handwriting input function cannot be used for the writing operation temporarily, and the writing operation needs to be performed by other devices. Obviously, if display devices of different models are used, different live course programs need to be provided during live course, that is, a live course program with a handwriting input function needs to be configured for a touch screen display device, and a live course program without a handwriting input function needs to be configured for a common display device.

Because live-broadcast class aiming at the student end and the teacher end, the program platform needs to provide two versions of programs. In the above situation, if the models of the display devices used by the student terminals are different, the program platform needs to maintain more versions of programs, which inevitably results in too high maintenance cost of the platform. Therefore, in order to reduce development cost, the program platform can provide the first program of the same version for the student-side display devices of different models, that is, the display devices of different models can be compatible with two display modes of different forms, wherein the two display modes include a first direct-playing interface with a handwriting input function and a first direct-playing interface without the handwriting input function.

Therefore, when configuring the first program on the display devices of different models, it is necessary to control automatic display of the handwriting input function in the live interface according to whether the display device is a touch screen.

In some embodiments, the scene of the first program is configured for the student side display device, different students use different display devices, and different display devices may have different models. Therefore, when the student starts the first program, the adopted student-side display device needs to firstly inquire whether the student-side display device is configured with the handwriting input capability, so as to accurately determine whether the handwriting input function control needs to be displayed in the first direct-playing interface.

In some embodiments, when developing a display device, a developer needs to configure whether to start a handwriting input capability of a model according to the model, whether CPU and memory resources of the model meet use requirements, and other factors. When the model is a touch screen and the CPU, the memory resource and the like meet the requirements, the handwriting input capability is configured for the display equipment; and when the model is a common screen, even if the CPU, the memory resource and the like meet the requirements, the handwriting input capability is not configured for the display equipment.

In some embodiments, after completing the brush pen capability and model configuration of each display device, a developer obtains function configuration information and stores the function configuration information in a server, and the server correspondingly stores the function configuration information of each display device according to the identification information. When a live-broadcast class is in class, the first program needs to query the server for information such as the model of the device and the brush capability configuration according to the current device capability to determine whether to display the handwriting input function control.

In some embodiments, terminal devices with the same hardware configuration may display the handwriting input function control when the conditions are met and not display the handwriting input function control when the conditions are not met due to different installed software versions.

In some embodiments, the student-side display device with the handwriting input function can manually turn off or turn on the handwriting input function, and the student-side display device can synchronize changed information to the teacher-side display device.

FIG. 10 illustrates an interaction diagram that automatically demonstrates a control method of a handwriting input function, in accordance with some embodiments; FIG. 11 illustrates a flow diagram for a method of controlling an auto-show handwriting input function, according to some embodiments. The embodiment of the invention provides a display device, which is applied to a student end display device and comprises: a display configured to present a first live interface generated upon launching a first program; the device comprises a memory, a first program and a second program, wherein the memory is configured with the first program for realizing online live lessons; a controller connected to the display and the memory, respectively, and configured to perform the following steps in performing the control method for automatically exhibiting the handwriting input function, referring to fig. 10 and 11:

and S11, responding to an application starting instruction for starting the first program, and sending a handwriting input function query instruction to the server, wherein the handwriting input function query instruction is used for indicating the server to query whether the local terminal is configured with a handwriting input function.

Before a live-broadcast class is taken, a student triggers a first program configured on display equipment used by the student in a remote controller or voice mode to generate an application starting instruction, and a controller responds to the application starting instruction to call up a display interface of the first program, namely, a first live-broadcast interface is generated and displayed in a display. One form of display of the first live interface can be seen in the interface contents shown in fig. 7.

When a student starts a first program, a controller of the student end display device generates a handwriting input function query instruction and sends the handwriting input function query instruction to the server, and the server queries whether the device is configured with a handwriting input function or not according to the handwriting input function query instruction of the student end display device. If the device for sending the query instruction of the handwriting input function is a touch screen type, the display device is configured with the handwriting input function, and at the moment, the server sends an instruction supporting the handwriting input function to the corresponding display device at the student end; if the device for sending the query instruction of the handwriting input function is of a common screen type, the display device is not configured with the handwriting input function, and at the moment, the server sends an instruction which does not support the handwriting input function to the corresponding display device at the student end.

In some embodiments, the subject querying the display device as to whether the handwriting input function is configured is a server, rather than the device itself. The server realizes the query of the handwriting input function, can reduce the occupation of CPU and memory resources of the display equipment, and avoids influencing the normal operation of the display equipment.

Because there are many students who take lessons on the live broadcast class, when several students respectively start the live broadcast class programs configured on the respective display devices, the respective used display devices at the student ends all generate handwritten input function query instructions and respectively send the handwritten input function query instructions to the server. At this time, the server may receive a plurality of handwritten input function query instructions simultaneously, and in order to ensure that the server can accurately return a corresponding handwritten input function query result to each student-side display device, the student-side display devices need to carry respective identification information when sending the handwritten input function query instruction, and the identification information is used for identifying at least one of model information, hardware configuration information, and version information of the display devices.

FIG. 12 illustrates a flow diagram of a method of sending a handwritten input function query instruction, in accordance with some embodiments. In some embodiments, referring to fig. 12, the controller, in executing the application start instruction for starting the first program, sending a handwriting input function query instruction to the server, is further configured to perform the steps of:

and S111, receiving an application starting instruction for starting the first program.

And S112, responding to the application starting instruction, and acquiring the local terminal identification information, wherein the local terminal identification information is used for identifying at least one of model information, hardware configuration information and version information of the local terminal display equipment.

And S113, generating a handwriting input function query instruction based on the home terminal identification information, wherein the handwriting input function query instruction comprises the home terminal identification information.

And S114, sending the handwriting input function query instruction to the server, wherein the handwriting input function query instruction is used for instructing the server to query a handwriting input function query result of the display equipment corresponding to the home terminal identification information according to the home terminal identification information.

When a student starts a first program configured in display equipment used by the student, an application starting instruction is generated, and the server responds to the application starting instruction and acquires local terminal identification information. The identification information is a unique identification corresponding to the display equipment and is used for distinguishing different student-side display equipment.

In some embodiments, to ensure uniqueness, the identification information of the display device may be generated based on the related information of the device and the random character string, and thus, the controller is further configured to perform the following steps when performing the acquiring of the local identification information:

and 1111, acquiring the model information, version information and hardware configuration information of the local terminal display device when the first program is started.

And step 1112, generating the local terminal identification information based on the model information, the version information, the hardware configuration information and the randomly generated character string of the local terminal display equipment.

After the first program is started, a controller of the display device acquires model information, version information and hardware configuration information of the device, wherein the model information comprises a touch screen model and a common screen model, the hardware configuration information comprises hardware information such as a CPU (Central processing Unit) and memory resources, and the version information comprises information such as a system version of the device.

And meanwhile, randomly generating a character string, and generating local terminal identification information by using the model information, the version information, the hardware configuration information and the randomly generated character string. The model information, the version information and the hardware configuration information are used for distinguishing hardware structures of different display devices, and the randomly generated character strings are used for further distinguishing different display devices, so that the situation that identification information of display devices with the same hardware structures is the same is avoided. Therefore, the home terminal identification information generated based on the model information, the version information, the hardware configuration information and the random character string has uniqueness.

After the student end display equipment acquires the home terminal identification information, a handwritten input function query instruction carrying the home terminal identification information can be generated and sent to the server. And after receiving the handwritten input function query instruction, the server analyzes the instruction to obtain corresponding identification information, and further queries a handwritten input function query result corresponding to the student-side display equipment based on the unique identification information.

The query result of the handwriting input function comprises two contents, one is that the handwriting input function is supported, and the other is that the handwriting input function is not supported.

And S12, if the query result of the handwriting input function returned by the server is that the home terminal has the handwriting input function, displaying a handwriting input function control in the first direct-playing interface.

Referring to fig. 10 (a), the student-side display device a is configured with a first program, and executes step S11 and related steps, and queries the server whether the student-side display device a is configured with a handwriting input function, and if the server returns a handwriting input function query result supporting the handwriting input function to the student-side display device a, the student-side display device a displays a handwriting input function control in a corresponding first direct-broadcast interface thereof.

FIG. 13 illustrates a schematic diagram of a first direct-play interface exhibiting handwriting input functionality controls, in accordance with some embodiments. Referring to another display form of the first live-action interface shown in fig. 13, if the student-side display device a is a touch screen model, it has a handwriting input function, so that when the first program is started, a handwriting input function control, such as a "brush" control displayed in the functional area in fig. 13, is synchronously displayed in the generated first live-action interface.

And S13, if the query result of the handwriting input function returned by the server is that the home terminal does not have the handwriting input function, not displaying the handwriting input function control in the first direct-broadcasting interface.

Referring to fig. 10 (B), the student side display device B is configured with the first program, and executes step S11 and related steps, and queries the server whether the student side display device B is configured with the handwriting input function, and if the server returns a handwriting input function query result that does not support the handwriting input function to the student side display device B, the student side display device B does not display the handwriting input function control in the corresponding first direct broadcast interface.

Referring again to the first direct-view interface shown in fig. 8, the handwriting input functionality control is not shown in the interface. If the student side display device B is of a common screen type, the student side display device B does not have a handwriting input function, so that a handwriting input function control is not displayed in the generated first direct-playing interface when the first program is started.

Different students enter a live course to study, and according to the models of the display devices used by the students, such as a common screen display device and a touch screen display device, the different students can respectively see different first direct-playing interfaces, namely the first direct-playing interface with the handwriting input function control and the first direct-playing interface without the handwriting input function control are displayed, so that the two interfaces of the first program of the same version adopted by the application can be compatibly displayed.

When different display devices start a live course program, the step of reporting the home terminal identification information to the server is required to be executed, so that the server issues the step of whether a handwriting input function switch is started or not, namely whether a handwriting input function control needs to be displayed in a first live interface or not. Therefore, different display devices can run the first program of the same version, whether the handwriting input function control needs to be displayed or not is automatically determined in a mode of reporting the home terminal identification information, so that interfaces of two different forms can be displayed in a compatible mode, a program platform does not need to maintain programs of different versions for different machine types, and development cost is reduced.

The display equipment with the handwriting input function control display function can enable corresponding students to participate in shared handwriting input function operation directly in a touch mode, the display equipment without the handwriting input function control display function can not enable the corresponding students to participate in the shared handwriting input function operation directly, and if the students want to participate in interaction, the display equipment needs to be realized by means of other external equipment.

In some embodiments, if the student uses a common screen display device, the display of the student does not have a touch function, and therefore, the student cannot directly input related information (scribble, drawing, and the like) in a touch manner. However, information input may be achieved by externally connecting a device to the display device, for example, the externally connected device may be a terminal providing a touch input function. The student uses a touch pen or a finger to paint, draw and the like on a terminal providing a touch input function to generate input information, the input information is transmitted to a display device at the terminal, the display device displays the content in a live broadcast interface after receiving the input information and specifically displays the content in an answer area or a lecture area, and the student using a common screen display device can participate in the sharing operation of the handwriting input function.

Because the common screen display device of the external device can also realize the handwriting input function, when the student end display device adopting the common screen reports the capability to the server, the server identifies the display device as the device configured with the handwriting input function. Therefore, when the student-side display device starts a live course program (such as a first program), the result of the query of the handwriting input function to the server is the result with the handwriting input function, and at the moment, the handwriting input function control is displayed in a live course interface of the student-side display device adopting a common screen.

Students participate in the operation of sharing the handwriting input function, and need to obtain the authorization of paintbrushes of teachers, and the display equipment at the teacher end needs to know whether the display equipment used by each student participating in a live-broadcast class has the handwriting input function. Therefore, after each student end display device obtains the respective handwriting input function configuration condition, the teacher end display device is instantly and synchronously informed, so that the teacher can determine which students can obtain the handwriting input function authorization and which students cannot obtain the handwriting input function authorization, and the normal operation of the live broadcast class is ensured. The student end display equipment capable of obtaining the authorization of the handwriting input function comprises touch screen display equipment and common screen display equipment externally connected with a touch input terminal.

In some embodiments, in executing the control method for automatically showing a handwriting input function, after learning the result of the query of the handwriting input function, the controller is further configured to execute the following steps: after receiving a handwritten input function query result returned by the server, sending the handwritten input function query result to teacher-side display equipment, and displaying a first authority control button used for representing the control authority of the student-side display equipment with the handwritten input function and a second authority control button used for representing the control authority of the student-side display equipment without the handwritten input function by the teacher-side display equipment, wherein the first authority control button is in a triggerable state, and the second authority control button is in a non-triggerable state.

After inquiring the respective handwriting input function inquiry result, each student end display device needs to send the respective handwriting input function inquiry result to the teacher end display device in time, and the teacher end display device generates a corresponding student list according to the handwriting input function configuration condition of each student end display device so as to display whether the corresponding student can participate in sharing the handwriting input function operation according to the received different handwriting input function configuration conditions. In some embodiments, whether each student-side display device can participate in the shared handwriting input function operation can be clarified by showing the authority control button in the second live interface.

The student list comprises a first operation item and a second operation item, the first operation item shows the student name and a first authority control button corresponding to the student side display device with the handwriting input function, and the second operation item shows the student name and a second authority control button corresponding to the student side display device without the handwriting input function. The first authority control button is in a triggerable state and has a control authority corresponding to the handwriting input function of the student-side display device; the second authority control button is in an untriggerable state and does not have the control authority of the handwriting input function of the corresponding student-side display equipment.

For example, the student side display device a sends a result with a handwriting input function to the teacher side display device, the student side display device B sends a result without a handwriting input function to the teacher side display device, the teacher side display device generates a student list according to the handwriting input function configuration conditions of the student side display device a and the student side display device B, generates a first operation item based on the result sent by the student side display device a, and generates a second operation item based on the result sent by the student side display device B. And synchronously displaying a first authority control button of the control authority of the student side display device with the handwriting input function in the first operation item, and displaying a second authority control button of the control authority of the student side display device without the handwriting input function in the second operation item. Therefore, the authority control button displayed by the teacher side comprises two display forms of having the control authority of the handwriting input function and not having the control authority of the handwriting input function. When the handwriting input function is shared, a teacher can only select students with the handwriting input function to participate in the sharing of the handwriting input function, namely, the teacher can only start the handwriting input function of the corresponding student end by triggering the first authority control button to authorize the handwriting input function.

And when the teacher clicks a first authority control button in a second live broadcast interface of the teacher-side display device, generating a handwriting input authorization instruction so as to authorize the handwriting input function of the student-side display device corresponding to the first authority control button. At this moment, the student end display equipment receives the handwriting input authorization instruction, and the configured handwriting input function can be called up to perform handwriting input operation.

In this scenario, the controller in the student-side display device is further configured to perform the following steps:

step 141, receiving a handwriting input authorization instruction sent by the teacher-side display device, where the handwriting input authorization instruction is an instruction generated when the teacher-side display device triggers the first permission control button.

And step 142, responding to the handwriting input authorization instruction, and starting the handwriting input function control to be in a triggerable state.

Step 143, responding to the triggering of the handwriting input function control in the triggerable state, generating a handwriting input function call instruction, wherein the handwriting input function call instruction is used for calling the handwriting input function so as to perform handwriting input operation in the first direct-broadcast interface.

The student does not have the right of actively opening the handwriting input function control configured in the student-side display device used by the student-side display device, and can be opened only after being authorized by the teacher side, namely, although the handwriting input function control is displayed in the first direct-broadcasting interface of the student-side display device, the control is in an triggerable state under the condition that the authorization of the teacher is not obtained. Therefore, in the course of live broadcast, if a student needs to participate in the course of live broadcast through the handwriting input function, the teacher can click the first authority control button corresponding to the student in the student list presented in the second live broadcast interface of the teacher, and the handwriting input function of the device where the student is located is started, so that the student end obtains the authorization of the handwriting input function.

And the teacher end triggers the first authority control button to generate a handwritten input authorization instruction, and the handwritten input authorization instruction is sent to the corresponding student end display equipment. After receiving the handwriting input authorization instruction, the student end display device starts the trigger state of the configured handwriting input function control to enable the student end display device to be in a triggerable state. Meanwhile, in order to inform students that the students have obtained the authorization of the handwriting input function. And synchronously popping up a prompt in the first direct-playing interface, wherein the prompt content can be 'you have obtained the authorization of the handwriting input function and can perform handwriting input operation'.

After seeing the prompt content, the student can trigger the handwriting input function control in a mode of a touch control pen or fingers to generate a handwriting input function starting instruction, and the handwriting input function starting instruction is used for starting a handwriting input function so as to perform handwriting input operation in the first direct-playing interface.

Therefore, the embodiment of the invention provides a display device, which executes an automatic handwriting input function query strategy when a first program is started, and queries whether the server has a handwriting input function or not. When the device has a handwriting input function, displaying a handwriting input function control on a first direct-playing interface; when the handwriting input function is not available, the handwriting input function control is not displayed on the first live broadcast interface, so that the first program can be compatible with two display modes in different forms, the two live broadcast class interfaces are compatible for display, the live broadcast class program of one version can be adapted to all display devices, development and maintenance of multi-version programs are not needed, and the development cost is reduced.

When the first program is started, each student-side display device sends the handwriting input function query results which are automatically queried to the teacher-side display device respectively, so that a teacher can select students with the handwriting input function to participate in sharing the paintbrush.

FIG. 14 illustrates another flow chart of a method of controlling an auto-show handwriting input function, according to some embodiments. The embodiment of the invention provides display equipment which is applied to teacher end display equipment and comprises: a display configured to present a second live interface generated upon launching the second program; a memory configured with a second program for implementing live on-line lessons; a controller connected to the display and the memory, the controller being configured to perform the following steps in performing the control method for automatically presenting the handwriting input function, referring to fig. 10 (c) and 14:

and S21, after the second program is started, receiving a handwriting input function query result sent by the student side display device, wherein the handwriting input function query result is a result of the student side display device requesting the server to query whether the student side is configured with a handwriting input function.

When a live class is in class, the teacher starts a second program configured on the display equipment used by the teacher in the form of a remote controller or voice to generate an application starting instruction. And the controller responds to the application starting instruction, invokes a display interface of the second program, namely generates a second live broadcast interface and displays the second live broadcast interface in the displayer.

In some embodiments, the live lesson needs to be initiated by the teacher, so that after the teacher starts the second program, the corresponding notification is pushed to each student display device, and after receiving the notification, the students start their corresponding first programs. When the student terminals start the respective first programs, the student terminals automatically inquire the respective handwriting input function configuration conditions of the server at the same time, and send the respective handwriting input function inquiry results to the teacher terminal display equipment.

Therefore, after the teacher-side display device starts the second program, the handwriting input function query result sent by each student-side display device may be received, where the handwriting input function query result refers to a result that the student-side display device requests the server to query whether the local terminal is configured with the handwriting input function, and the specific implementation process may refer to the contents of steps S11 to S13 and the related implementation contents provided in the foregoing embodiment, and is not described herein again.

After receiving the query result of the handwriting input function of each student end display device, the teacher end display device can display the configuration condition of the handwriting input function of each student in a list form in order to determine whether each student can enjoy the authorization of the handwriting input function.

In some embodiments, while the second live interface is being presented, the controller in the teacher-side display device is further configured to perform the following steps: receiving a handwritten input function query result sent by each student terminal display device; and displaying a student list in a second live broadcast interface based on each handwritten input function query result, displaying a first operation item and a second operation item in the student list, displaying a student name and a first authority control button corresponding to student end display equipment with a handwritten input function in the first operation item, displaying a student name and a second authority control button corresponding to student end display equipment without the handwritten input function in the second operation item, wherein the first authority control button is in a triggerable state, and the second authority control button is in a non-triggerable state.

Fig. 15 illustrates a schematic diagram of a list of students in a second live interface, in accordance with some embodiments. Referring to fig. 15, after receiving the handwritten input function query results sent by the plurality of student side display devices, the teacher side display device generates a student list based on the name of each student and the handwritten input function query results. And the student list is displayed in a live broadcast information display area in the second live broadcast interface, and the number of students currently participating in live broadcast on line, the name of each student and an authority control button of a handwriting input function are displayed on the student list.

In order to distinguish whether display equipment used by different students has a handwriting input function or not, when a student list is generated by the teacher-side display equipment, students participating in a live course are distinguished according to a handwriting input function query result, namely a first operation item and a second operation item are generated, the first operation item displays student information of the handwriting input function configured on the display equipment, and the second operation item displays student information of the handwriting input function not configured on the display equipment.

In some embodiments, the first operation entry shows a student name and a first authority control button corresponding to a student side display device with a handwriting input function, the second operation entry shows a student name and a second authority control button corresponding to a student side display device without a handwriting input function, the first authority control button is in a triggerable state, and the second authority control button is in a non-triggerable state.

In some embodiments, the teacher-side display device may generate the student list after receiving the result of the query of the handwriting input function sent by each student-side display device, and thus, the generation of the student list may exist in different application scenarios. An application scenario is that when a live course is started at the initial stage and a teacher just enters a live room and does not actually go to school, a student list can be generated based on a handwritten input function query result sent by display equipment used by students entering the live room at the moment. In another application scenario, in the process of live-broadcast class, some students enter the live-broadcast room after having started to go to class due to delay, that is, when the students continuously enter the live-broadcast room, the teacher-side display device can update the student list in real time according to the handwritten input function query result sent by the student-side display device currently entering the live-broadcast room. The teacher end can perform corresponding handwriting input function authorization operation based on the information presented by the latest student list.

Because some display devices used by students do not have the handwriting input function and cannot participate in the sharing operation of the handwriting input function, the second authority control button displayed in the student list does not have the control authority of the handwriting input function of the corresponding student-side display device. And the other part of the display equipment used by the students has the handwriting input function and can participate in the sharing operation of the handwriting input function, so that the first authority control button displayed on the student list has the control authority corresponding to the handwriting input function of the student side display equipment. That is, the handwriting input function query result corresponds to the presentation form of the authority control button.

In some embodiments, the display form of the authority control buttons may be a white brush pattern (a first authority control button) and a gray brush pattern (a second authority control button), the white brush pattern represents a control authority of a handwriting input function with a corresponding student-side display device, and a teacher may click a trigger; the gray brush pattern represents that the control authority of the handwriting input function of the corresponding student-side display device is not available, and a teacher cannot click the trigger. In order to distinguish the authority control button with control authority from the authority control button without control authority, the display form of the button may also be other colors or forms, which is not specifically limited in this embodiment.

And S22, when the query result of the handwriting input function is that the handwriting input function is provided, displaying a first operation item corresponding to each student-side display device with the handwriting input function on a second live broadcast interface, wherein the first operation item comprises a first authority control button with the handwriting input function control authority corresponding to the student-side display device.

And S23, when the query result of the handwriting input function is that the handwriting input function is not available, displaying a second operation item corresponding to each student-side display device without the handwriting input function on a second live broadcast interface, wherein the second operation item comprises a second authority control button without the control authority of the handwriting input function corresponding to the student-side display device.

When the teacher-side display device receives the handwriting input function query result sent by the student-side display device as having the handwriting input function, the display device used by the corresponding student is indicated to be a touch screen type, or an ordinary screen type externally connected with a touch input terminal is configured with the handwriting input function, and further the operation of sharing the handwriting input function can be participated in. Therefore, a first operation item corresponding to the student-side display device with the handwriting input function is displayed on the second live broadcast interface, and a first authority control button with the handwriting input function control authority corresponding to the student-side display device, such as a button with a white brush pattern, is presented in the first operation item.

When the teacher-side display device receives that the handwriting input function query result sent by the student-side display device does not have the handwriting input function, the display device used by the corresponding student is of a common screen type, and a touch input terminal is not connected externally, the display device is not configured with the handwriting input function, and further cannot participate in the operation of sharing the handwriting input function. Therefore, a second operation item corresponding to the student-side display device without the handwriting input function is displayed on the second live broadcast interface, and a second authority control button without the handwriting input function control authority corresponding to the student-side display device, such as a gray brush pattern button, is presented in the second operation item.

For example, referring again to the student list shown in fig. 15, 300 students participating in a live class are schematically listed for information of three students. If the display devices used by the student A and the student C have handwriting input functions, correspondingly displaying a first operation item in a second live broadcast interface, and displaying a first authority control button of a white painting brush pattern in the first operation item, namely generating the first operation item based on the student A, displaying the student A and a first authority control button of the white painting brush pattern on the right side of the student A in the first operation item, and generating the first operation item based on the student C, and displaying the first authority control button of the white painting brush pattern on the right side of the student C, wherein the first authority control button in a student list from top to bottom has the handwriting input function control authority of the student end display device A, and the third authority control button has the handwriting input function control authority of the student end display device C.

If the display device used by the student B does not have the handwriting input function, displaying a second operation item in a second live broadcast interface, and displaying a second authority control button of the gray painting brush pattern in the second operation item, namely generating the second operation item based on the student B, and displaying the student B and the second authority control button of the gray painting brush pattern on the right side of the student B in the second operation item, which indicates that the second authority control button from top to bottom in the student list does not have the handwriting input function control authority of the student end display device B.

Because the first authority control button of the white brush pattern can be triggered by clicking, and the second authority control button of the gray brush pattern can not be triggered by clicking, when a teacher needs to select a student to share a handwriting input function, the first authority control button of the white brush pattern can be triggered to initiate the handwriting input function authorization for the corresponding student, so that the student participates in the handwriting input interaction.

In some embodiments, when a student is selected for a handwriting input interaction, the controller in the teacher-side display device is further configured to perform the following steps:

and 241, when the student is authorized to perform handwriting input operation, receiving a handwriting input authorization instruction generated when a first authority control button corresponding to the student is triggered.

And 242, sending the handwriting input authorization instruction to the student end display device corresponding to the first authority control button for executing the triggering operation, wherein the handwriting input authorization instruction is used for starting a triggering state of a handwriting input function control displayed by the student end display device in the first direct-broadcasting interface, and the student clicks the handwriting input function control in the triggerable state to start a handwriting input function so as to perform handwriting input operation in the first direct-broadcasting interface.

Referring again to the second live interface shown in fig. 7, a handwriting input function control, such as a "brush" control in fig. 7, is presented in a live operation button area displayed below the main function area. Because the model of the teacher-side display device can be a touch screen or a common screen, when the teacher side starts the second program, the teacher side also automatically sends the local-side identification information to the server so as to inquire whether the display device where the teacher side is located has a handwriting input function. When the function of handwriting input is found, displaying a handwriting input function control below the main function area; and if the user does not have the handwriting input function, the handwriting input function control is not displayed below the main function area. The execution process of whether the handwriting input function control is displayed or not in the second live broadcast interface is the same as the related steps of the control method for automatically displaying the handwriting input function executed by the student-side display equipment, and the description is omitted here.

FIG. 16 illustrates an interface diagram for the teacher side to scribble using handwriting input functionality according to some embodiments. Referring to fig. 16, if a handwriting input function control is displayed in the second live broadcast interface, the teacher may trigger the handwriting input function control, and the teacher may implement scribbling on the lecture interface through the handwriting input function control in the display area of the lecture function mode. And in the lecture function mode, the course content area of the second live broadcast interface is switched to display the lecture display area, and the lecture display area is used for simulating a blackboard so as to simulate the process of painting on the blackboard by a teacher in a real lecture scene.

Under the lecture mode, after the teacher writes a question through the handwriting input function control, one student can be selected to participate in answering the question. Although the handwriting input function control is displayed in the first direct broadcasting interface of the student end, the student end cannot actively trigger the handwriting input function control, and if the student end wants to use the handwriting input function, the student end needs to obtain the authorization of the teacher end.

In some embodiments, in the process of a live broadcast class, the handwriting input function of the student-side display device is not started, the handwriting input function control displayed in the first live broadcast interface is in a gray state, that is, a state that cannot be triggered, and the student cannot actively trigger the handwriting input function to perform handwriting input operation. When a student uses the handwriting input function and needs to obtain authorization of a teacher end, namely when the teacher end authorizes the handwriting input function of a certain student, the display equipment used by the student receives a handwriting input authorization instruction, the handwriting input function of the display equipment at the student end is started, and a handwriting input function control in the first direct-playing interface is switched to be white, namely, a state which can be triggered is obtained. The display forms of the non-triggerable state and the triggerable state corresponding to the handwriting input function control are not only displayed by adopting gray and white patterns, but also displayed by using other forms so as to distinguish two different trigger states.

After the student end display device obtains the authorization of the handwriting input function of the teacher end, the handwriting input function of the student end display device is started, the student can trigger a handwriting input function control which is displayed in a first direct-playing interface and is in a triggerable state, and after the triggering, the student can adjust the handwriting input patterns such as the shape, thickness, color and font of a painting brush on the generated painting brush setting interface. After the adjustment is completed, the student uses a stylus or a finger to perform scribbling and other operations in the touch screen display (or the display of the touch input terminal), so as to complete information input and realize interactive operations such as answering.

When the student end does not obtain the authorization of the handwriting input function of the teacher end, if the student triggers the handwriting input function control, the handwriting input function control in the current state is in the triggerable state, so that the handwriting input function control of the student end does not respond to the triggering of the student, and a prompt pops up in the first direct-playing interface, and the prompt content can be that 'you do not obtain the authorization of a painting brush and cannot perform handwriting input operation'.

In some embodiments, when a teacher wants to select a student authorization handwriting input function, i.e., when the teacher writes a question on the lecture, a handwriting input function authorization may be initiated for the student with the handwriting input function to allow the student to participate in answering the question. In a specific implementation, the teacher triggers any one of the first authority control buttons having control authority of the handwriting input function displayed in the student list, for example, if the teacher wants to select student a for answering, the first authority control button of the white brush pattern displayed on the right side of student a is triggered. If the teacher wants to select student C for answering, the first permission control button of the white brush pattern displayed on the right side of student C is triggered.

And after the first authority control button is triggered, generating a handwritten input authorization instruction, and sending the handwritten input authorization instruction to the student end display equipment corresponding to the triggered first authority control button. For example, if the teacher triggers the first authority control button corresponding to the student a, the handwritten input authorization instruction is sent to the student side display device a used by the student a. And if the teacher triggers the first authority control button corresponding to the student C, sending the handwriting input authorization instruction to the student end display equipment C used by the student C.

The live course content displayed in the course content area of the first live interface is the same as the live course content displayed in the course content area of the second live interface, so that after the teacher switches the lecture mode and completes the theme layout, the course content area of the first live interface synchronously displays the theme.

After a certain student-side display device receives a handwriting input authorization instruction sent by a teacher-side display device, the student-side display device receives a prompt and displays prompt information in a first direct-playing interface, for example, "receiving brush authorization, can scribble". The student end display equipment receives the handwriting input function authorization of the teacher, the handwriting input function is started, and the student can answer with the handwriting input function, namely, the student can scribble at the corresponding position of the course content area in the first direct-playing interface in a mode of touching the display screen.

For example, if the student-side display device a starts the handwriting input function of the student-side display device a after receiving the handwriting input authorization instruction sent by the teacher-side display device, the student a can use the handwriting input function to scribble in the course content area. The content painted by the student A is displayed in the course content area and synchronously displayed for the teacher end display equipment and the rest of the student end display equipment, so that the handwriting input interactive content of the student A is synchronously displayed on the display equipment used by the teacher and the student who live the class.

In some embodiments, after the student completes the use of the handwriting input function, the teacher end needs to cancel the authorization of the handwriting input function of the student end, and at this time, the teacher clicks the first authority control button corresponding to the student in the second live broadcast interface again, generates a handwriting input authorization cancellation instruction, and sends the handwriting input authorization cancellation instruction to the student end display device. At this time, a cancel brush authorization prompt is displayed in a first direct-view interface in the student-side display device, and the prompt message may be that "your handwriting input function has been cancelled. After the handwriting input authorization of the student end is cancelled, the handwriting input function control of the student end is in an untriggerable state again, the teacher end can continue to carry out subsequent courses, or the teacher end clicks the handwriting input function control displayed in the main function area of the second live broadcast interface again to obtain the handwriting input function again, and the teacher end can continue to use the configured handwriting input function to continue to paint.

In some embodiments, if the teacher-side display device wants to end the handwriting input operation for subsequent normal courses, the teacher may click the handwriting input function control displayed in the second live interface to end the invoking of the teacher-side handwriting input function. After the handwriting input function is cancelled, the teacher can continue with the subsequent lessons.

In some embodiments, since the teacher needs to click the authority control button in the student list presented in the second live interface when sharing the handwriting input function with any student. However, since the authority control buttons include a button having a control authority for a handwriting input function of the student-side display device and a button not having a control authority for a handwriting input function of the student-side display device, when a teacher clicks one of the authority control buttons, a selection error may occur, that is, the teacher should trigger the first authority control button, but mistakenly clicks the second authority control button.

For example, the teacher may want to trigger a first authority control button having the control authority of the handwriting input function of the student-side display device, but may mistakenly trigger a second authority control button having no control authority of the handwriting input function of the student-side display device. The authority control button with the control authority of the handwriting input function of the student-side display device can execute the trigger operation, and the authority control button without the control authority of the handwriting input function of the student-side display device can not execute the trigger operation.

Therefore, in order to ensure that the authorized operation of the handwriting input function of the teacher end is normally performed, when the teacher triggers the second authority control button without the control authority of the handwriting input function of the student end display device, an error prompt is popped up in the second live broadcast interface, and the prompt content can be that the device used by the student selected by the teacher is not configured with the handwriting input function. After seeing the error prompt, the teacher can know that the selected student can not use the handwriting input function, namely can not answer the question, and needs to select other students with the handwriting input function to answer the question.

In some embodiments, the teacher end is provided with a time-effect for each question when the student answers the question. For example, if the answer time provided by the teacher end to the student is 30 seconds, when the teacher end selects a certain student to authorize the handwriting input function, the handwriting input function of the student end display device is turned on, and the 30-second countdown control and the corresponding question are displayed in the course content area of the student end display device, and the student needs to complete answering within 30 seconds.

If the student uses the handwriting input function to process overtime, namely the answer is overtime, the server automatically withdraws the question, and meanwhile, the handwriting input function obtained by the student end is authorized to be cancelled, so that the student can not answer the question any more. If the input content is wrong or the input is messy when the student answers the question by obtaining the handwriting input function, the teacher end invokes the blackboard eraser function to erase the content input by the student. The blackboard eraser function can be configured in the second live broadcast interface and displayed in a control mode, a teacher can click and trigger the blackboard eraser function, and the blackboard eraser function is cancelled when the teacher clicks again.

In some embodiments, when the teacher end authorizes a student to perform the handwriting input function, the teacher end display device needs to send a handwriting input authorization instruction to the student end display device through the server. In order to avoid that the student end display equipment cannot receive the handwriting input authorization instruction due to network communication abnormity, and the teacher end display equipment cannot know the condition, so that the time limit can be added to the handwriting input authorization instruction when the live course temporarily enters a waiting state. If the instruction is sent overtime, the student end display device still does not receive the instruction, namely the aging of the instruction is invalid, the teacher end needs to click the first authority control button corresponding to the student once again, and the handwritten input authorization instruction is sent again.

In some embodiments, after the student end completes the handwriting input function operation, the teacher end needs to recover the authorization of the handwriting input function of the student end. If the recovery of the handwriting input function authorization of the teacher end fails due to the abnormal network communication, the teacher end display equipment can report to the server for forced recovery. If the student end still makes a disorder writing and a disorder drawing after answering, the teacher end can kick the student out of the live broadcast room and disconnect all message transmission between the student and the live broadcast room. If the student wants to continue listening, the student needs to click again to enter the first direct playing interface.

The function of forcibly recovering the authorization of the handwriting input function and forcibly disconnecting the communication of the students can be configured in the second live broadcast interface and correspondingly displayed in a control form, and when a certain function needs to be executed, a teacher clicks the corresponding control. And when the teacher clicks the forced recovery control or forcibly disconnects the communication control, sending a corresponding instruction to the server, and executing an operation corresponding to the received instruction by the server, such as forced recovery handwriting input function authorization or forced disconnection of student communication.

Therefore, when the second program is started, the display device provided by the embodiment of the invention obtains the query result of the handwriting input function sent by each student-side display device after executing the automatic handwriting input function query. And when the query result of the handwriting input function is that the handwriting input function is provided, displaying an authority control button with the control authority of the handwriting input function corresponding to the student terminal display equipment on a second live broadcast interface. When the handwritten input function query result is that the handwritten input function is not available, the right control button which does not have the control right of the handwritten input function corresponding to the student-side display equipment is displayed on the second live broadcast interface, so that a teacher can select students with the handwritten input function to participate in sharing the handwritten input function, the purpose that the handwritten input function of the student side can be controlled by the teacher side is achieved, and development cost is further reduced.

When configuring the display device, a developer configures whether to start the handwriting input capability of the model according to the model and whether the CPU and the memory resources of the model meet the use requirements and other factors. When the model is a touch screen and the CPU, the memory resource and the like meet the requirements, the handwriting input capability is configured for the display equipment; and when the model is a common screen, even if the CPU, the memory resource and the like meet the requirements, the handwriting input capability is not configured for the display equipment.

After completing the handwriting input capability and the model configuration of each display device, a developer obtains function configuration information and stores the function configuration information to a server, and the server correspondingly stores the function configuration information of each display device according to the identification information. When a live-broadcast class is in class, the first program needs to query the server for information such as the model of the equipment, the handwriting input capability configuration and the like according to the current equipment capability to determine whether to display the handwriting input function.

FIG. 17 illustrates yet another flow diagram for a method of controlling an auto-show handwriting input function, according to some embodiments. Referring to fig. 10 and 17, an embodiment of the present invention provides a server, including: a database configured to store functional configuration information of a display device; a controller connected with the database, wherein when the student display device executes the query strategy of the automatic handwriting input function, the controller in the server is configured to execute the following steps:

and S31, responding to the handwritten input function query instruction sent by the student side display equipment, and querying a database for a handwritten input function query result corresponding to the student side display equipment.

When the student-side display device starts the first program, the student-side display device automatically generates a handwriting input function query instruction to the server to query whether the device in which the student-side display device is located has a handwriting input function.

After receiving a handwritten input function query instruction sent by student display equipment, a controller of the server sends the handwritten input function query instruction to the database so as to acquire function configuration information stored in the database, and a handwritten input function query result of the student display equipment is acquired based on the function configuration information and the handwritten input function query instruction.

Because when carrying out the live class and going on class, can have a plurality of students simultaneously for there is the handwritten input function inquiry instruction that a plurality of student end display device sent, for the student end display device of difference of being convenient for distinguish, guarantee the accuracy of handwritten input function inquiry result, student end display device obtains the painting brush ability of this end to the server based on the only sign of this end.

In some embodiments, when querying the configuration of the handwriting input function, the controller, in executing a handwriting input function query instruction sent by the student-side display device, queries the database for a result of the handwriting input function query corresponding to the student-side display device, and is further configured to perform the following steps:

and 311, responding to the handwriting input function query instruction sent by the student side display device, and analyzing the home terminal identification information of the student side display device carried in the handwriting input function query instruction.

And step 312, inquiring a handwriting input function inquiry result corresponding to the home terminal identification information in the function configuration information stored in the database based on the home terminal identification information of the student terminal display equipment.

In order to ensure the accuracy of result query, because the student-side display device generates the handwritten input function query instruction based on the home-side identification information, the home-side identification information is used to identify the model information of the home-side display device, and the generation process of the home-side identification information may refer to the relevant contents of steps S111 to S114, and steps 1111 to 1112 provided in the foregoing embodiment, which are not described again here.

In order to facilitate the server to obtain the query result of the handwriting input function corresponding to the student-side display device, the controller analyzes the query instruction of the handwriting input function to obtain the home terminal identification information of the student-side display device carried in the instruction. The home terminal identification information is the only identification of the student terminal display equipment, and the function configuration information stored in the database comprises the relevant function configuration corresponding to the identification information, so that the handwritten input function query result corresponding to the home terminal identification information of the student terminal display equipment can be queried in the function configuration information according to the home terminal identification information.

The handwriting input function configuration of the display equipment is related to the model thereof, namely, if the display equipment is of a touch screen model, the handwriting input function is configured; if the screen is of a common screen type, the handwriting input function is not configured. Therefore, when the database is queried based on the home terminal identification information of the student terminal display equipment, the controller can obtain two query results.

If the home terminal identification information of the student terminal display equipment represents the touch screen type, inquiring a handwriting input function inquiry result corresponding to the home terminal identification information in function configuration information stored in a database to be provided with a handwriting input function; and if the home terminal identification information of the student terminal display equipment represents the common model, inquiring the handwriting input function inquiry result corresponding to the home terminal identification information in the function configuration information stored in the database as that the handwriting input function is not available.

And S32, sending the handwritten input function query result to the student side display equipment so that the student side display equipment determines the display result of the handwritten input function control in the first direct-playing interface.

After the server inquires a corresponding handwritten input function inquiry result in the database according to the handwritten input function inquiry instruction sent by the student display equipment, the handwritten input function inquiry result is returned to the corresponding student display equipment. And the student terminal display equipment determines whether a handwriting input function control needs to be displayed in the first direct-playing interface according to the handwriting input function query result, and displays the handwriting input function control in the first direct-playing interface if the handwriting input function query result returned by the server is that the terminal has the handwriting input function. For example, if the query result of the handwriting input function returned by the server is that the local terminal does not have the handwriting input function, the handwriting input function control is not displayed in the first direct-playing interface. The related process refers to the contents of steps S11 to S13 and related implementation contents provided in the foregoing embodiments, and details are not repeated here.

The student end display equipment further needs to send a handwriting input function query result to teacher end display equipment, the teacher end display equipment presents a student list in a second live interface according to the handwriting input function query result sent by each student end display equipment so as to display authority control buttons corresponding to the handwriting input functions of the student end display equipment, and whether each student end display equipment can participate in sharing handwriting input operation or not is determined in a mode that the authority control buttons are displayed in the second live interface. The related process refers to the contents of steps S21 to S23 and related implementation contents provided in the foregoing embodiments, and details are not repeated here.

Therefore, when the student display device starts the first program, the student display device executes the automatic handwriting input function query strategy to query whether the student display device has the handwriting input function. The server returns the handwritten input function query result to the student side display device, so that when the server has the handwritten input function, a handwritten input function control is displayed on the first direct-playing interface; when the handwriting input function is not available, the handwriting input function control is not displayed on the first live interface, so that the first program can be compatible with two display modes in different forms, the two live interfaces are compatible for display, the first program of one version can be adapted to all display devices, development and maintenance of programs of multiple versions are not needed, and development cost is reduced.
