referring to fig. 1, a first embodiment of the present invention provides a live course interaction method, which can be executed by a live server. In particular, execution by one or more processors in a live server to implement the steps of:
and S3, receiving an interactive exercise instruction initiated by the teacher live broadcast end, extracting pre-selected exercise questions from the exercise question database according to the interactive exercise instruction, and sending the exercise questions to the student live broadcast end. Wherein, the student live broadcast end has a plurality ofly.
It should be noted that the live online lesson is a way in which teachers and students use internet equipment to attend lessons in real time through the internet in different places. The teacher live broadcast end is generally a computer and is externally connected with a camera, so that the content of a preset window of the computer and the picture of the teacher on the scene can be shared in real time. The live broadcast end of the student comprises a smart phone, a tablet personal computer, a notebook computer, a desktop computer and even a television.
The exercise database can be recorded into the server by using the internet equipment such as a classroom live broadcast terminal and the like before a teacher goes on class, or can be originally stored in the server. The problem database at least comprises the question information and the answer information of the practice problems.
The teacher can click a specific icon on the teacher live broadcast end to generate an interactive exercise instruction and send the interactive exercise instruction to the server. When the server receives the interactive exercise instruction, the exercise which is selected by the teacher in advance and is related to the current online lesson content is extracted from the exercise database and is sent to the student live broadcast end for the students to carry out on-site exercise.
In this embodiment, the number of teacher live broadcast ends is one, and the number of student live broadcast ends is multiple. In other embodiments, the number of teacher live broadcasting terminals may also be multiple, and during live broadcasting, switching can be performed among multiple teacher live broadcasting terminals. The invention does not limit the number of each live broadcast terminal.
And S4, receiving the answer content sent by each student live broadcast end, identifying whether the answer content is correct or not, and then sending the identification result to the teacher live broadcast end.
Specifically, since the student live broadcast end is various, the answer content includes a text form that is directly typed and answered on the live broadcast end, a picture form that is uploaded by taking a picture after being answered on paper, and a drawing board form that is handwritten on a touch screen. When the answer content is in the form of a picture, handwriting on the picture needs to be extracted and then character recognition is carried out, and when the answer content is in the form of a drawing board, handwriting information is contained, so that character recognition can be directly carried out, and the character form does not need to be recognized. How to identify the text information on the answer contents in various forms belongs to the prior art, and the invention is not repeated herein.
In this embodiment, the recognition result includes the accuracy of the answer. Step S4 specifically includes:
and S4a, receiving the answer content sent by each student live broadcast end.
And S4b, recognizing the text information of the answer content, matching the text information with the correct answer, and judging whether the answer content is correct.
Specifically, the text information of the answer content and the text information of the correct answer are paired through an algorithm, so that whether the answer is correct or not is a function which can be realized by a person skilled in the art without creative labor, and the realization principle of the invention is not repeated herein.
It can be understood that whether the answer is correct can be judged by whether the final result of matching the answer contents is the same. The step of answering the question and the result of answering the question can be matched at the same time to judge whether the steps are completely the same.
And S4c, counting the accuracy of the answer content, generating information and sending the information to the teacher live broadcast end.

For the teacher to decide whether to continue teaching new content or review old content next. The time required for the above steps is often very short due to the increase in internet speed and the increase in computing power of internet devices. The teacher can know the knowledge points of the students in time, and the teaching strategy can be adjusted in real time. The teaching quality is greatly improved.
In this embodiment, the number of teachers is much smaller than that of students. The teacher teaches away from caring for all students.
And S5, receiving an interactive explanation instruction sent by the teacher live broadcast end, and establishing local connection between the student live broadcast end with the correct answer and the student live broadcast end with the wrong answer so as to make the student with the correct answer explain for the student with the wrong answer.
Specifically, in the live broadcasting process, the connection between the teacher live broadcasting end and the student live broadcasting end is established. Therefore, the student live broadcast end can directly see the content of the teacher live broadcast end and the sound of the teacher. When receiving the interactive explanation instruction, the picture of the teacher live broadcast end is not pushed to the student live broadcast end, but the student live broadcast end with correct answer and the student live broadcast end with wrong answer are locally connected. It will be appreciated that in a live broadcast process, multiple local connections are established to allow individual communication between correctly answered students and incorrectly answered students.
The same locally connected live broadcast end shares an electronic whiteboard and a voice channel. The students can perform operations such as painting brushes and typing on the electronic whiteboard so as to perform character communication and perform voice communication in real time. Thereby leading the students with correct answers to remotely explain the students with wrong answers one by one.
It is understood that local connections may be established, or one-to-many. For example, two student live broadcast terminals with correct answer are simultaneously connected to a student live broadcast terminal with wrong answer, or a student with correct answer is simultaneously connected to two student live broadcast terminals with wrong answer.
Preferably, all student terminals are tablets, or computers. The electronic whiteboard has a larger screen, and is convenient for students to operate on the electronic whiteboard. An electronic whiteboard is a drawing board in a screen that can perform typing or handwriting input using a brush. The touch screen can be used for direct touch input, and the computer can be used for input through peripheral equipment such as a mouse.
More preferably, the teacher live broadcast end can check the real-time content of any one local connection, so that the communication condition among students can be checked. Teachers share an electronic whiteboard and a voice channel with a local connection while viewing the local connection, thereby explaining the local part of an individual classmate.
And S6, receiving an interactive explanation ending instruction sent by the student live broadcast end, disconnecting the local connection corresponding to the interactive explanation ending instruction, and restoring the live broadcast of the network lesson.
And when the students with correct answers explain the students with wrong answers, the students with wrong answers click a preset button on the live student ends to generate an interactive explanation ending instruction and send the instruction to the server. The server disconnects the local connection between the plurality of student live broadcast ends corresponding to the local connection after receiving the interactive explanation ending instruction, and pushes the video stream of the teacher live broadcast end to the student live broadcast ends again.
It can be understood that the interactive explanation ending instruction can also be generated by a teacher after the teacher clicks a preset button on a live broadcast end point, when the server receives the interactive explanation ending instruction sent by the live broadcast end of the teacher, a plurality of local connections are disconnected, and video streams of the live broadcast end of the teacher are pushed to all live broadcast ends of students to carry out live broadcast of the network class.

So that the teacher can explain the students with wrong answers individually.
And S10, receiving a local explanation ending instruction sent by the live broadcast end of the teacher, disconnecting the local connection corresponding to the local explanation instruction, and restoring the live broadcast of the network lesson.
Besides the students can give tutoring one by one, the teacher can give independent explanation to the students who answer wrong questions. Specifically, a teacher generates a local explanation instruction by clicking a specific button on a teacher live broadcast end, and after receiving the instruction, a server sends a new exercise to students with correct answer, and meanwhile, local connection between the teacher live broadcast end and the student live broadcast end with wrong answer is established, so that the teacher gives independent explanation to the students with wrong answer. Thus, the time of students who answer correct questions cannot be wasted. On the traditional class, a teacher explains the subject, all students listen to the subject, and the students with knowledge points are repeatedly listening to the subject, so that the significance is not great. In this embodiment, the student is screened out for exercise, rather than participating in listening and speaking. The time of the students is fully utilized, and the students cannot listen and talk repeatedly. The classroom efficiency is greatly improved.
Alternatively, in an alternative embodiment of the present invention, on the basis of the above-mentioned embodiment, in step S4c,
and when the accuracy is more than 50%, the information carries an interactive explanation recommending instruction. The interactive explanation recommending instruction is used for reminding the teacher to trigger the interactive explanation instruction.
When the accuracy is 30% to 50%, the information carries the wrong explanation recommendation instruction. The wrong question explanation instruction is used for reminding the teacher to trigger the wrong question explanation instruction.
When the accuracy is less than 30%, the information carries a question answer recommending instruction. Wherein, the exercise answer recommending instruction is used for reminding the teacher to trigger the exercise answer instruction.
Specifically, a plurality of buttons are arranged on the live teacher terminal and are used for generating an interactive explanation instruction, a practice question answer instruction, a wrong question explanation instruction and an interactive explanation recommendation instruction respectively. And when the teacher live broadcast terminal receives an interactive explanation recommending instruction, a wrong question explanation recommending instruction or a question answer recommending instruction, highlighting the corresponding button to remind a user to click the button and trigger the corresponding instruction.
On the basis of the foregoing embodiment, in an optional embodiment of the present invention, before step S3, the method further includes:
and S1, acquiring the video stream of the teacher live broadcast end and the video stream of the student live broadcast end, generating live broadcast video streams and pushing the live broadcast video streams to each live broadcast end.
And S2, judging whether the live broadcast reaches a preset condition. And when the live broadcast is judged to meet the preset condition, generating an interaction reminding instruction, and sending the interaction reminding instruction to the live broadcast end of the teacher, so that the live broadcast end of the teacher reminds the teacher to interact according to the interaction reminding instruction.
In particular, to ensure that live online sessions are not boring. Therefore, the system can remind the teacher to interact under the condition that the preset conditions are met. Thereby preventing the teacher from forgetting the interaction only by looking at the lecture. The efficiency of the live broadcast of the network lesson is ensured.
In this embodiment, step S2 optionally includes:
and S2a, judging whether the live broadcast time reaches a preset time length.
S2b, when the live broadcast time is judged to reach the preset time, an interaction reminding instruction is generated.
In this embodiment, the time is set as a judgment standard, and the teacher is reminded to interact when the predetermined time is reached. Specifically, after receiving the interactive reminding instruction at the live broadcast end of the teacher, the live broadcast end of the teacher can pop up to remind the teacher of interaction, and also can remind the teacher of interaction by flashing an icon corresponding to the interactive explaining instruction and other predetermined actions.
In another embodiment, step S2 includes:
and S2A, analyzing the postures of the students according to the video stream of the live broadcast end of the students.
And S2B, judging whether the students make difficulties according to the postures, and calculating the number of the students making difficulties.
S2C, judging whether the number of people making difficulties reaches a preset value or a preset proportion.
S2D, when the number of people suffering from sleepiness is judged to reach a preset value or a preset proportion, an interactive reminding instruction is generated.
In this embodiment, all the live broadcasting ends of the students are provided with cameras, and in the live broadcasting process of the teacher, the server receives video streams of the live broadcasting ends of the students at the same time, wherein the video streams of the live broadcasting ends of the students contain images of the students; because the people have specific actions of frequently nodding heads, yawning, lying prone and sleeping and the like when making a trouble. Therefore, the video stream of the live broadcast end of the student is analyzed, and the server can judge whether the student attending class is sleepy or not. And counts the number of students who make a hardy. Specifically, the video stream is analyzed to determine whether people in the video stream are stranded, which is a scheme that can be implemented by those skilled in the art without creative work.
Only when the number of the students in the poverty reaches the preset number or proportion, the interactive reminding instruction is generated. The generation time of the interactive reminding instruction is more humanized and more targeted, and the interaction quality of a classroom can be improved.
