The course level means that courses can be designed according to the receiving capacity of students to adapt to students in different levels, for example, the courses are graded according to the standards of long teaching time but much interpretation content, easy understanding/standards/short content but difficulty understanding of the students; and for the same teaching content, teaching scripts of different levels can be correspondingly provided to generate different virtual teaching videos so as to realize the level teaching. The standard script can be modified based on a standard script according to the course setting information to generate teaching scripts with different levels or different teaching styles.

The virtual teacher may be integrated with the virtual environment, teaching aids, etc., for example; assigning values for parameters corresponding to the virtual teacher based on action parameters and sound parameters in the virtual teacher setting information; displaying the virtual teacher in the virtual environment based on course setting information to generate the virtual teaching scene.
The virtual teaching scene can be constructed by using unity3D, unity, cos and other game engines, and the virtual environments can be different according to different disciplines and chapters, for example: in the geographic teaching, aiming at the seasonal wind teaching link, the system can stand in a universe view to see the formation and the change of the seasonal wind on the earth.
As described above, the avatar may be determined for the virtual teacher according to the settings of the student user. The student user may also select the action characteristics of the virtual teacher, such as exaggerated, standard, and so on. The student user may also select the sound characteristics of the virtual teacher, such as male, female, neutral, soft, sweet, cartoon character characteristic sounds, and so forth.
Different virtual scenes are needed to match the setting of course content to adjust the position of the virtual teacher. For example, in a biological class, when plants such as flowers, plants and trees are explained, the position and the size of the virtual teacher can be adjusted and changed at any time according to the displayed image of the teaching content, and in the teaching process of the virtual teacher, the virtual teacher can be hidden in a virtual scene in a scene without the need of the virtual teacher, for example, in the calculation process of a mathematical formula on a blackboard.

The classroom performance means that the virtual teacher performs some interesting performance to enrich the classroom content. Classroom experiments generally guide students to do virtual experiments. Answering in a classroom: the virtual teacher answers questions of students interactively, and the answering link behind the questions of the students searches relevant answers from the massive question bank/information bank by means of data mining and provides the answers for the students through the virtual teacher.
In some embodiments, virtual tutoring may include, for example: the virtual teacher explains knowledge points based on the virtual teaching scene and interactively answers questions with the user; and/or the virtual teacher and the user perform virtual experiments based on the virtual teaching scene.

In some embodiments, the question information may be retrieved from a preset question bank to obtain the return information. After the return information is obtained, the return information is played through a virtual teacher through a voice processing technology, and when needed, further explanation can be carried out, or related information is searched again according to questions of students and provided for student users. The return information includes: whether answer information of the question exists, recommended answers of similar questions and other information, for example, the return information may be that the question is currently riddle or not, and a student in the same class needs to give an answer "
In the process of asking questions by students, the virtual teacher can firstly pause the current teaching content (according to the prior art, the time can be very short and can be hidden in repeated asking content or other performances of the virtual teacher, and the user can not generally perceive the content), and after the questions to be asked are explained, the explanation of the current course is continued. In the process of asking information by students, the virtual teacher can also complete the explanation of the content of the current course or a certain section in the current course first and then carry out the explanation of the problem.
Wherein, the virtual teacher and the user perform virtual experiments based on the virtual teaching scene, including: acquiring virtual experiment data based on the course setting information; building a virtual experiment environment based on the virtual experiment data; interacting with the user in the virtual experiment environment to complete the virtual experiment.

More specifically, the action script may include a plurality of action parameters, and the action parameters for the virtual teacher may be generated through machine learning by mapping the face key points/body key points/gesture key points to corresponding portions of the virtual teacher one by one to drive the virtual teacher to perform various actions, and by using actions of different actual characters. Different virtual characters can be provided with different action parameter amplitudes for selection by the student user. The motion parameters may be discreet, extended, force, etc., and the invention is not limited thereto.
In S304, the voice script data is converted into sound by using a voice synthesis technique. Speech synthesis is a technique for simulating a human being with an electronic computer and some specialized devices to produce speech.
The sound parameters can adopt a speech synthesis technology to convert the script into sound. The voice of teachers or ordinary people can be collected, and after post-processing, various characteristic voices are generated to be selected by student users. The sound parameters can also be divided into various types of sounds of males, females, adolescents, middle-aged people and the like for selection by users.
In S306, the action script data is associated with the face key points, body key points, and gesture key points of the virtual teacher, so that the virtual teacher executes corresponding actions according to the action script data.

The experimental environment of the small-hole experiment can be specifically shown in fig. 5, and the experimental steps of the small-hole experiment are as follows:
1. lighting the candle, and adjusting the heights of the candle and the screen to ensure that the flame, the small holes and the center of the frosted glass screen of the candle are approximately on the same straight line;
2. moving the position of the candle or the frosted glass screen;
3. observing the image, the closer the candle is to the small hole or the farther the ground glass screen is from the small hole, the larger the obtained image.
In the first step, the heights of the virtual candle and the virtual screen are input by a student user, and the student user can adjust the heights by sliding the touch screen or the mouse; at the second step, the student user may continue to move the position of the virtual candle or virtual frosted glass; in a third step, the student user can click on the local impact of the magnifying virtual frosted glass to observe the results.
