Detailed Description
To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
Before explaining the embodiments of the present application in detail, an application scenario related to the embodiments of the present application will be described.
Traditional on-line live broadcast teaching needs schedule the teaching time according to mr's time, and when mr's time is inconvenient, for example mr is sick, and can't implement the teaching, then can delay normal teaching progress, and student self can't arrange the time of getting into class according to self hobby. Therefore, as artificial intelligence is applied to the teaching field, the adoption of virtual teachers to implement teaching has slowly become a new trend of future development of the teaching field. The interaction method in the virtual teaching provided by the embodiment of the application can be applied to the teaching scene through the virtual teacher.
Next, a system architecture related to the interaction method in virtual teaching provided in the embodiment of the present application is described.
Fig. 1 is an architecture diagram of an interactive system for virtual education according to an embodiment of the present application. As shown in figure 1 of the drawings, in which,
the system 100 includes a terminal 101 and a server 102. The terminal 101 and the server 102 are connected by wireless or wired connection to communicate with each other.
The terminal 101 may be deployed with a camera, the terminal 101 may collect audio and video data of a student in a class based on the deployed camera and send the audio and video data to the server 102, and the server 102 may determine a behavior type of the student according to the audio and video data and determine a feedback behavior type according to the behavior type, so as to implement that a virtual teacher takes the determined behavior as a feedback behavior. In addition, the server 102 may also adjust the teaching content according to the knowledge mastery degree of the student, so as to enable the virtual teacher to teach according to the adjusted teaching content.
That is, through the interaction method in the virtual teaching provided by the embodiment of the application, the behavior types of the students intelligently identified by the virtual teacher can be simulated, and the corresponding feedback behaviors are executed according to the behavior types of the students. For example, the feedback behavior may be the appearance of a more beautiful teacher in order to reward students or a more ugly teacher in order to punish students. In addition, through the interaction method in the virtual teaching provided by the embodiment of the application, the degree of knowledge mastery of a student by a virtual teacher can be simulated to be tested, and a corresponding feedback behavior is executed like a real teacher according to a test result, wherein the feedback behavior can be that review content is added and is used for reviewing or repeatedly teaching knowledge points which are not mastered by the student. The feedback behaviors can increase the interaction between the virtual teacher and the student, and avoid the lack of interaction between the virtual teacher and the student to reduce the learning interest of the student.
A specific implementation manner of the server executing the interaction method in the virtual teaching provided by the embodiment of the present application will be described in detail in the following embodiments, and a description thereof is not necessarily provided herein.
In addition, in this embodiment of the present application, the terminal 101 may be a device such as a tablet computer, a desktop computer, a mobile phone, and the like, and the server 102 may be a server or a server cluster that is used in this embodiment to determine a display manner of a virtual teacher so as to enable the virtual teacher to perform some feedback behaviors, which is not limited in this embodiment of the present application.
It should be noted that, the above description is given by taking an example where the server executes the interaction method in the virtual teaching provided in the embodiment of the present application. Optionally, the interaction method in the virtual teaching provided in the embodiment of the present application may also be applied to a terminal, and this is not specifically limited in the embodiment of the present application.
The following explains the interaction method in virtual education provided in the embodiment of the present application in detail. The following embodiments take an example in which a server executes an interaction method in virtual teaching provided in the embodiments of the present application.
Fig. 2 is a flowchart of a virtual education method provided in an embodiment of the present application, and is applied to a server. Referring to fig. 2, the method includes the following steps.
Step 201: the server determines the behavior type of the student, and the behavior type is used for indicating the behavior of the student in the virtual teaching process.
Wherein the behavior type of the student is used for indicating the student's behavior in class, for example, the behavior in class may include sleeping in class, shaking head and shaking brain in class, eating things in class, listening to speech seriously in class, answering questions positively in class, etc. The embodiment of the application does not limit the specific types of the lesson taking behaviors, and when the interaction method in the virtual teaching is applied, the server can set various types of lesson taking behaviors according to the requirements.
In a possible implementation manner, the possible implementation procedures of step 201 are: collecting audio and video data of students in a virtual teaching process; and determining the behavior type of the student according to the audio and video data and the behavior recognition model. The behavior recognition model is used for recognizing the type of the trip based on the audio and video data. That is, in the embodiment of the present application, the behavior type of the student may be determined by means of AI (Artificial Intelligence) recognition.
It should be noted that the behavior recognition model may be a trained model directly obtained from a database, or may be a model temporarily trained by a server.
The implementation manner of the behavior recognition model obtained by training may be: the method comprises the steps of obtaining a plurality of sample audio and video data and a label of each sample audio and video data in the plurality of sample audio and video data, wherein the label of each sample audio and video data is used for indicating the behavior type of the behavior of a student indicated in the sample audio and video data. The plurality of sample audio-video data are input into an initialized neural network model. And if the output behavior type of the initialized neural network model is inconsistent with the behavior type indicated in the label of each sample audio-video data, adjusting parameters in the initialized neural network model. And repeating the operation until the behavior type output by the adjusted neural network model is consistent with the behavior type indicated in the label of each sample audio/video data, and calling the neural network model with the parameters adjusted for the last time as a behavior recognition model.
The behavior recognition model provided in the embodiments of the present application is described above by taking a neural network model as an example, and it should be noted that the behavior recognition model is not limited to the neural network model, and may be other types of learning models.
Step 202: and if the behavior type of the student is the target behavior type, the server acquires the target feedback behavior type matched with the target behavior type, wherein the target feedback behavior type is used for indicating the behavior responding to the behavior of the student.
In the embodiment of the application, the virtual teacher can only feed back a part of behavior types of the students so as to relieve the pressure of the server on processing data. For example, when the current behavior type of the student is a significant negative behavior type or a positive behavior type, the virtual teacher needs to give feedback on the behavior types. Therefore, it is necessary to first determine whether the behavior type of the student is the target behavior type. Wherein the target behavior type refers to a behavior that requires a virtual teacher as feedback.
In one possible implementation manner, the possible implementation process of determining whether the behavior type of the student is the target behavior type is as follows: setting a plurality of behavior types, and setting feedback behavior types matched with the behavior types one by one. And traversing the plurality of behavior types, and determining the behavior type as a target behavior type when the behavior type of the current student is judged to be one of the plurality of behavior types. Accordingly, when it is determined that the current behavior type of the student is not one of the plurality of behavior types, there is no need to feed back the behavior of the student through the virtual teacher.
When the server determines that the behavior type of the student is the target behavior type, a target feedback behavior type matching the target behavior type needs to be obtained, so as to implement the feedback of the virtual teacher to the behavior of the student through the following step 203. The implementation manner of obtaining the target feedback behavior type matched with the target behavior type may be: acquiring a behavior type corresponding relation, wherein the behavior type corresponding relation comprises a plurality of behavior types and a plurality of feedback behavior types which are matched with the behavior types one by one; and determining a target feedback behavior type matched with the target behavior type according to the behavior type corresponding relation.
Table 1 shows a corresponding relationship between a behavior type and a feedback behavior type provided in the embodiments of the present application. As shown in Table 1, the behavior types include behavior type 1, behavior type 2, and behavior type N. Wherein, the behavior indicated by the behavior type 1 goes to sleep in class, the feedback behavior type of the virtual teacher matched with the behavior type 1 is the feedback behavior type 1, and the behavior indicated by the feedback behavior type 1 is the expression of frowning. The behavior indicated by the behavior type 2 is shaking the head in class, the feedback behavior type of the virtual teacher matched with the behavior type 2 is the feedback behavior type 2, and the behavior indicated by the feedback behavior type 2 is the expression of making angry. The behavior indicated by the behavior type 3 is listened to in class, the feedback behavior type of the virtual teacher matched with the behavior type 3 is the feedback behavior type 3, and the behavior indicated by the feedback behavior type 3 is a changeable image.
TABLE 1
Step 203: and the terminal displays the animation corresponding to the target feedback behavior type, wherein the animation comprises the feedback behavior of the virtual teacher aiming at the behavior of the student.
Since the feedback behavior of the virtual teacher to the behavior of the student is included in the animation, the behavior of the virtual teacher to the student can be implemented as the feedback behavior through step 203.
For example, based on table 1, as shown in fig. 3, when the behavior type of the student is shaking the head in class, the behavior indicated by the feedback behavior type of the virtual teacher is an angry expression, and thus, the animation corresponding to the current virtual teacher includes an angry expression. In fig. 3, the related introduction of the word "name" displayed in the right block diagram of the virtual teacher is used to indicate the current teaching content.
As shown in fig. 4, when the behavior type of the student is to take a class to listen to the talk seriously, the feedback behavior type of the virtual teacher is to change the lovely character. Thus, the animation to which the virtual teacher currently corresponds includes the appearance of a machine cat that is changed to be lovely. The associated introduction of the word "name" shown in the block diagram to the right of the virtual teacher in FIG. 4 is also used to indicate the current tutorial.
In addition, the behavior of the virtual teacher to the student as the feedback behavior may include sound in addition to the motion, and thus, the server may also play the voice corresponding to the animation in synchronization after acquiring the target feedback behavior type matching the target behavior type.
For example, as shown in fig. 5, the virtual teacher intelligently recognizes that the behavior types of the current student are: when shaking the head and shaking the brain on class, virtual mr makes the expression of engendering qi to synchronous broadcast pronunciation are reminded: please listen to the talk seriously in class. The associated introduction of the word "watch" shown in the block diagram to the right of the virtual teacher in FIG. 5 is used to indicate the current tutorial.
In the embodiment of the application, the behavior type of a student is determined; if the behavior type of the student is the target behavior type, acquiring the type of the target feedback behavior matched with the target behavior type; and displaying the animation corresponding to the target feedback behavior type, wherein the animation comprises the feedback behavior of the virtual teacher aiming at the behavior of the student. That is, in this application embodiment, the virtual teacher can make feedback in time according to the behavior of the student, so the interaction link between the student and the teacher is increased in the virtual teaching process, thereby the learning interest of the student is greatly increased, and the user viscosity of the virtual teaching mode provided by this application embodiment is correspondingly improved.
Through the embodiment, the feedback of the virtual teacher to the behavior type of the student can be simulated through AI identification. In addition, the server may simulate the feedback of the knowledge mastery degree of the student by the virtual teacher through the following embodiments.
Fig. 6 is a flowchart of another interaction method in virtual education according to the embodiment of the present application. As shown in fig. 6, the method includes the following steps:
step 601: the server determines the knowledge mastery degree of the student on first teaching content, wherein the first teaching content is teaching content before the current time and within a first time length from the current time.
In this application embodiment, in order to realize that virtual mr can in time adjust teaching content according to student's knowledge mastery degree, the server can confirm the student to the mastery degree of teaching content in this period of time after imparting knowledge to students through virtual mr for a period of time, promptly, the server confirms the knowledge mastery degree of student to first teaching content. The first teaching content refers to teaching content before the current time and within a first time length from the current time.
In one possible implementation manner, the possible implementation procedures of step 601 are: determining test content according to the first teaching content; displaying the test content; acquiring the response information of the student based on the test content; and determining the knowledge mastery degree of the student on the first teaching content according to the response information.
The first time length may be a time length of a lesson, and the time length of the lesson may be preset by the server or may be set manually.
For example, the duration of the class may be 40 minutes. The server determines a test content according to the teaching content 40 minutes before the current time, namely the teaching content of the previous lesson, wherein the test content can be '30 words included in the teaching content of the previous lesson are identified', namely the test content comprises the 30 words and prompt information aiming at the 30 words, and the prompt information is used for prompting the student to identify the 30 words. The server pushes the test content to the user side corresponding to the student, and the user side displays the test content, so that the user side can collect the reply information of the student and return the reply information of the student to the server.
As shown in fig. 7, the test content displayed on the current client display interface is the word card "watch", and meanwhile, the virtual teacher sends out a prompt voice: please read the word with the same students. And the terminal starts to collect the audio and video after the teacher sends out the prompt voice, and finishes recording after 5s, and stores the collected audio and video. The collected audio and video information is response information, the stored audio and video is compared with the correct pronunciation of the watch in the background database, and the mastering degree of the student on the word is determined according to the comparison result. The testing process for the other remaining 29 words can refer to the testing process for the word 'watch', and is not described in detail here. And after the 30 words are tested, determining a test score according to the test condition of the 30 words, and displaying the test score. The test score may represent a degree of knowledge mastery of the first instructional content by the student.
Step 602: the server acquires second teaching content, wherein the second teaching content refers to teaching content after the current time.
After determining the knowledge mastering degree of the student for the teaching content within a certain period of time through step 601, the server may adjust the teaching content to be performed next, so that the student can skillfully master the already-taught content, and therefore, the server needs to acquire the teaching content to be performed next, that is, the second teaching content.
In one possible implementation manner, the possible implementation procedures of step 602 are: acquiring a plurality of teaching segments and a teaching sequence number of each teaching segment in the plurality of teaching segments, determining one or more education sequence numbers which are adjacent to the teaching sequence number of the teaching segment corresponding to the first teaching content and are behind the teaching sequence number of the teaching segment corresponding to the first teaching content according to the teaching sequence number of the teaching segment corresponding to the first teaching content in the step 601, and taking the teaching segment corresponding to the determined one or more education sequence numbers as a second teaching content.
For example, the server obtains a plurality of teaching fragments and a teaching sequence number of each teaching fragment in the plurality of teaching fragments, and assumes that the server obtains 5 teaching fragments, which are teaching fragment 1, teaching fragment 2, teaching fragment 3, teaching fragment 4, and teaching fragment 5. The teaching sequence number corresponding to the teaching fragment 1 is 001; the teaching sequence number corresponding to the teaching segment 2 is 002; the teaching sequence number corresponding to the teaching fragment 3 is 003, and the teaching sequence number corresponding to the teaching fragment 4 is 004; the teaching sequence number corresponding to the teaching fragment 5 is 005. If the first teaching content in the step (1) is teaching segment 1 and the corresponding teaching sequence number is 001, obtaining teaching segment 2 with the teaching sequence number of 002, wherein the teaching segment 2 is the second teaching content.
Step 603: the server adjusts the second teaching content according to the knowledge mastery degree of the student on the first teaching content.
In a possible implementation manner, the possible implementation procedures of step 603 are: determining the content to be reviewed according to the knowledge mastery degree of the student on the first teaching content; and adding the audio and video data corresponding to the content to be reviewed into the audio and video data containing the second teaching content.
After the audio and video data corresponding to the content to be reviewed is added to the audio and video data containing the second teaching content, the server can set a "teaching review" link in the teaching process, wherein the "teaching review" link is used for prompting the students to review the content to be reviewed. For example, the server may use a plurality of words included in a word card that is read by the student in the test content as the content to be reviewed, then present the content to be reviewed to the student based on the display interface, and the virtual teacher brings the plurality of words to the student for follow-up reading, so as to achieve review of the plurality of words by the student. As shown in fig. 8, the words in the test content that the student answered in error are: { Watch, egg, water, fly, sky, picture, have }, and displays the words on a display interface, and prompts the student to review the words through a virtual teacher. For example, the virtual teacher may be controlled to play the prompt message "please review the words".
For another example, the virtual teacher determines the test content included in the test content according to the teaching content in a month before the current time, where the test content may be a "teaching review test", and the "teaching review test" may be words that the students in the month wrongly read in all the test content, and performs a test again in the form of the "teaching review test", or may be a method of extracting a part of knowledge points in the word teaching content in a month before the current time, determining words included in the test content according to the knowledge points, and performing a test in the form of the "teaching review test". The server refers to the process of obtaining the test result in the above embodiment, and adjusts the teaching content included in the teaching outline according to the test result, for example, when the test result of the student is high, the "review of teaching" link included in each lesson may be deleted.
In the embodiment of the application, the server determines the knowledge mastery degree of the student on the first teaching content, acquires the second teaching content, and adjusts the second teaching content according to the knowledge mastery degree of the student on the first teaching content. In this application embodiment, because virtual mr can adjust the second teaching content according to the student to the knowledge mastery degree of first teaching content, consequently virtual teaching process can be more close real man mr's teaching process. That is, the virtual teacher can timely make feedback according to the knowledge mastering degree of the student, so that the interaction link between the student and the teacher is increased in the virtual teaching process, the learning interest of the student is greatly increased, and the user viscosity of the virtual teaching mode provided by the embodiment of the application is correspondingly improved. In addition, the teaching content can be adjusted in time according to the knowledge mastering conditions of students, and the teaching quality can be improved. All the above optional technical solutions can be combined arbitrarily to form an optional embodiment of the present application, and the present application embodiment is not described in detail again.
