Based on the hardware framework of the teaching equipment based on the virtual reality, the embodiment of the teaching method based on the virtual reality is provided. The teaching method based on the virtual reality aims to improve the enthusiasm of students for participating in interaction in class.
Referring to fig. 2, fig. 2 is an embodiment of the teaching method based on virtual reality, and the teaching method based on virtual reality includes the following steps:
and S10, establishing a virtual reality teaching scene on a preset virtual reality platform according to the current course.
The preset virtual reality platform is used for on-line virtual reality teaching, and can be realized by depending on a cloud server or a local server. Teacher end users and student end users can log in the virtual reality platform to give lessons/study in virtual reality. When virtual reality learning is performed, teachers and students present their character models.
The teaching scene is a virtual reality scene matched with a current course, and comprises basic teaching environments such as a room, a blackboard, a platform and a seat, and also comprises teaching props such as a three-dimensional teaching aid and a three-dimensional model for assisting teaching.
Specifically, when an online lecture is performed, the teacher and the student can log in a virtual reality teaching scene corresponding to the current course.
And S20, detecting the teaching mode of the current course.
Specifically, in the online virtual reality teaching of the present application, the teaching mode thereof includes, but is not limited to, a conventional teaching mode and an anonymous teaching mode. In the conventional teaching mode, role models of teachers and students are generated based on actual facial features and physical features of the teachers and students in real life, and user IDs of the teachers and the students are consistent with actual identities. In the anonymous teaching mode, the role model and the user ID of the teacher are consistent with those of the real life, and the role model and the user ID of the students are randomly distributed, so that the anonymous teaching mode has anonymity for the students, and the psychological safety of the students can be improved.
Therefore, before giving lessons, it is necessary to detect in which lesson giving mode the current lesson is.
And S30, if the current course is in an anonymous teaching mode, selecting a teacher model matched with the teacher end user from a preset teacher model library to distribute to the teacher end user when detecting that the teacher end logs in the virtual reality teaching scene.
Here, the preset teacher model library stores the role models of the teachers and the teacher ids (identity documents).
Specifically, when a teacher-side user logs in the virtual reality teaching scene, the role model matched with the login ID can be searched from a preset database through the login ID of the teacher side. After the role model matched with the login ID is found, the role model can be distributed to the teacher end user, and therefore the teacher appears in the virtual reality teaching scene in a corresponding image.
And S40, when the fact that the student end logs in the virtual reality teaching scene is detected, randomly selecting a student ID and a student model from a preset student model library to distribute to the current student end user, and enabling the student ID and the student model of any two student end users to be different.
The preset student model library comprises a student ID database and a student model database, wherein a plurality of IDs are stored in the ID database and are different from each other; the student model stores a plurality of character models, and the character models are different from each other. It should be noted that, in order to ensure that each student end user can be assigned a student ID and a student model, the number of IDs in the student ID database and the number of role models in the student model database are both greater than the actual number of students in the current class.
Specifically, when the student end user logs in the virtual reality teaching scene, a student ID and a student model can be randomly selected from a preset student model library and allocated to the current student end user. That is, the current student end user will appear with the student ID and the image of the student model in the current virtual reality teaching scene. Since the student IDs and the student models are randomly assigned, even if the users at the same student end are in different courses, the students IDs and the student models owned by the users are different. Therefore, the association between the image of the student in the virtual reality teaching scene and the real identity can be avoided, the psychological shy of the student can be reduced, the enthusiasm of the student in interacting with teachers and other students in the classroom can be improved, and the students can express their own ideas and viewpoints more courageously in the classroom. In addition, the students can not know each other after entering the virtual reality teaching scene, so that the communication frequency among the students in the class can be improved, the cognition of the students on each other can be deepened, and the harmonious atmosphere among the students can be cultivated.
It should be noted that, in order to ensure that the student IDs and the student models of any two student end users are different, when assigning the student IDs and the student models to the student end users, the unassigned student IDs and the student models are always selected from the student model library to the current student end user.
It can be understood that, the teaching method based on virtual reality of the technical scheme of the application randomly allocates the student ID and the student model to the student end user in the anonymous teaching mode, so that students can learn in the virtual reality teaching scene by the image completely different from the real identity, and thus, the psychologically shy feelings of the students can be reduced by the anonymity brought by the strange image, the students can express own thoughts and viewpoints more courageously in class, the enthusiasm of the students in interacting with teachers and other classmates in class is improved, and the teaching effect of teachers and the learning effect of students are improved. Therefore, the teaching method based on the virtual reality has the advantage of improving the enthusiasm of students for participating in classroom interaction.
In an embodiment, the virtual reality-based teaching method of the present application further includes:
and performing sound changing processing on the voice of the student end user and then playing the voice.
By the arrangement, the anonymity among students can be further improved, so that the students can positively express viewpoints in class.
As shown in fig. 3, in an embodiment, establishing a virtual reality teaching scene on a preset virtual reality platform according to a current course includes:
and S11, acquiring the era background associated with the current course.
The era background includes a chronological background, an environmental background, and the like. These contexts are associated with what the current lesson teaches. For example, when "Shudao difficultly" is taught, the chronological scene can be Tang dynasty, and the environmental scene can be Shudao; as another example, in learning newton's law of motion, its chronological background may be in the uk of the 17 th century and its environmental background may be under the apple tree.
And S12, acquiring matched teaching scene data from a preset teaching scene library according to the epoch background.
Specifically, after the era background associated with the current course is determined, teaching scene data matching the era background can be retrieved from the teaching scene data. Among them, in the teaching scene data matched with the era background, rooms, blackboards, lectures, chairs and the like with different styles are adaptively designed according to the different era backgrounds, for example, the rooms, blackboards, lectures, chairs and the like designed according to the architectural style and design style of the dynasty, or the rooms, blackboards, lectures, chairs and the like designed according to the architectural style and design style of the uk in the 17 th century.
And S13, establishing a virtual reality teaching scene on a preset virtual reality platform according to the teaching scene data.
Specifically, after the required teaching scene data is determined, a virtual reality teaching scene associated with the current course can be established on the virtual reality platform according to the teaching scene data.
It can be understood that the virtual reality teaching scene can be associated with the course of the course through acquiring the environment background related to the current course, so that the virtual reality teaching scene associated with the course knowledge point can be borrowed to enable the student to enter the learning state more quickly, and the profound memory of the student on the related knowledge point is enhanced, thereby being beneficial to improving the learning effect of the student.
As shown in fig. 4, in an embodiment, the virtual reality-based teaching method of the present application further includes:
and S110, acquiring identity information and human body data of the teacher, wherein the human body data comprises face data and body data.
Specifically, the identity information includes, but is not limited to, name, teaching discipline and position. The body data includes, but is not limited to, height, weight, and circumference; the facial data include, but are not limited to, eyebrows, eyes, nose, mouth, lips, chin, cheekbones, ears, hairstyle. It is worth mentioning that the human body data of the teacher can be obtained through detection of the depth sensor, so that the acquisition of the human body data of the teacher is simplified. Of course, in other embodiments, the teacher's body data may also be manually uploaded by the teacher.
And S120, establishing a teacher ID based on the identity information.
Specifically, a corresponding teacher ID is established based on the identity information of the teacher.
And S130, generating a teacher model based on the human body data.
Specifically, a corresponding teacher model is generated from body data and face data of the teacher. The teacher model generated by simultaneously adopting the body data and the face data of the teacher can enable the model to be close to the actual image of the teacher, so that students can recognize the teacher in different subjects.
And S140, binding the teacher ID with the corresponding teacher model, and storing the teacher ID in the preset teacher model library.
Particularly, after the teacher ID and the teacher model are bound, when the teacher end user logs in the virtual reality teaching scene, the corresponding teacher model can be quickly searched according to the teacher ID, and therefore the searching efficiency of the teacher model is improved.
By the scheme, the teacher model similar to the actual image of the teacher can be established, and the searching efficiency of the teacher model is improved.
As shown in fig. 5, in an embodiment, after the virtual reality teaching scene is established on the preset virtual reality platform according to the current course, the method further includes:
and S210, establishing a basic role model according to the current course.
Specifically, the establishing of the basic role model according to the current course includes acquiring a clothing style and a release style under the era background of the current course according to the era background of the current course, and establishing a corresponding basic role model based on the current clothing style and the hairstyle. Therefore, the established basic role model is more fit with the associated age of the current course, and the interest of learning is improved.
And S220, randomly changing model data of the basic role model based on a preset rule to generate a preset number of student models, wherein the model data comprises at least one of body data and face data of the basic role model.
The preset rule is used for limiting the inconsistency of each change of the basic role model, so that the generated student model has differences. The preset number can be adjusted adaptively according to the number of the students.
Specifically, the body data includes height, weight, and circumference, the face data includes eyebrow, eye, nose, mouth, lip, chin, cheekbone, ear, and hair style, and at least one of the above data may be randomly changed or different data may be changed for one of the data when different student models are generated. By the random change, student models of the differences can be generated.
By the scheme, the student model which accords with the background of the current course era can be established according to the current course I, so that different student models can be generated, the student models are more fit with the current course, and the interest of student learning is improved.

As shown in fig. 7, in an embodiment, the virtual reality-based teaching method of the present application further includes:
and S410, creating a virtual student in the virtual reality teaching scene based on the preset student model library.
Specifically, the virtual student is not a role of a certain student in the class in the virtual reality teaching scene, but refers to a student model controlled by the system AI (Artificial Intelligence). Since the number of student IDs and student models in the preset student model library exceeds the number of actual students in the class, one of the unassigned student IDs and student models in the student model library can be selected to create a virtual student.
And S420, setting the virtual students to answer the questions asked by the teacher end when the preset trigger conditions are met after the teacher end user asks the questions.
Specifically, by setting the trigger condition of the virtual student, the virtual student can actively answer the question after the teacher end user proposes the question. By the arrangement, on one hand, the situation that a teacher does not answer questions after providing the questions can be avoided, on the other hand, the virtual students can live in a classroom atmosphere, and then enthusiasm for driving other students to speak is promoted, so that the classroom activity degree is improved.
It can be understood that the mode of establishing the virtual students in the virtual reality teaching scene is beneficial to setting off the classroom atmosphere and driving the enthusiasm of the students for participating in classroom interaction.
In an embodiment, the preset trigger condition includes at least one of the following two conditions:
no student end user responds to the question to answer within a preset time after the teacher end user proposes the question; and
and receiving a directional roll call instruction sent by a teacher end.
Firstly, if no student end user responds to the question within a preset time after the teacher end sends a question, the desire of students in a class to answer the question is not high, or the students are shy of answering the question, at the moment, the virtual students can actively turn to the teacher end to feed back the answer intention based on the question, and answer the question after receiving a confirmation instruction fed back by the teacher end based on the answer intention.
Secondly, after the teacher end puts forward the question, if the virtual student receives the directional roll call instruction of the teacher end, the virtual student directly executes the operation of answering the corresponding question. It should be noted that, in order to facilitate the teacher end user to send a directional roll call instruction to the virtual students, when creating the virtual students, the information of the virtual students is synchronously sent to the teacher end user.
When either of the above two conditions is satisfied, the virtual student can actively answer the question posed by the teacher-end user.
As shown in fig. 8, in one embodiment, the virtual student answers a question posed by the teacher, including:
and S510, acquiring the questions posed by the teacher end user.
Specifically, the virtual student may first obtain voice data of the teacher-side user, recognize the voice of the teacher side according to the voice data, and then obtain the question presented by the teacher-side user by querying keywords in the voice of the teacher side.
S520, obtaining a reference answer from a preset answer library according to the question.
Specifically, the preset answer library stores reference answers matching with the questions. After the virtual student obtains the question provided by the teacher end user, the corresponding reference answer can be retrieved from the preset answer library according to the question. It is noted that in other embodiments, the teacher end user may also direct questions to the virtual students directly after presenting the questions.
S530, replying the question based on the reference answer.
Specifically, when answering a question, the virtual student gives a corresponding reference answer.
It can be understood that the teacher can store the questions to be asked and the matched reference answers in the class into the preset answer library when preparing the class, so that the virtual students can conveniently search the reference answers, and the condition that the virtual students cannot find the reference answers of the related questions can be avoided.
In an embodiment, the teaching method based on virtual reality further includes:
and the virtual students are set to authorize the control authority to a teacher end when receiving a take-over instruction of a teacher end user, and the teacher end is set to execute actions and voice in one of the teacher model and the virtual student model after acquiring the control authority of the virtual students.
The control authority comprises a voice authority and an action authority, the voice authority can control the virtual student to speak, and the action authority can control the virtual student to perform actions such as walking and raising hands.
After the teacher end is set to acquire the control authority of the virtual students, actions and voice are executed in one of the teacher model and the virtual student model, so that the problems of action repetition and voice repetition between the teacher model and the virtual student model are avoided.
By the arrangement, the teacher can acquire the control authority of the virtual students, and then can play the roles of answering questions, proposing questions and the like for the virtual students, so that the virtual students can speak adaptively according to the actual scene, the learning atmosphere of a classroom is further promoted, and the enthusiasm of other students participating in classroom interaction is improved.
