After the preparation is finished, the virtual demonstrator sends out an operation instruction to enter different demonstration modes.
And step S04, triggering a corresponding teaching mode according to the operation instruction, wherein the teaching mode at least comprises a teacher teaching sub-mode, a designated exercise sub-mode and a full-member exercise sub-mode.
In this embodiment, the teaching mode includes at least a teacher teaching sub-mode, a designated training sub-mode and a full-member training sub-mode, when the teacher teaching sub-mode is triggered, only the speaking function of the head-mounted VR device corresponding to the virtual teaching person is controlled to be turned on, the operation device is activated, and at the same time, the virtual operation device in the virtual teaching scene is controlled to be presented in the view angles of all the teaching subjects, in the teaching mode, the teaching mode is mainly explained by the teacher, so that the user except the teacher does not need to speak, and if necessary, the user can designate speaking; when the appointed exercise sub-mode is triggered, only the speaking function of the head-mounted VR equipment of the appointed educated person and the demonstrator is controlled to be started, and the operation equipment is activated; when the full-staff exercise sub-mode is triggered, the speaking function of the head-mounted VR equipment of all the trainees and the demonstrators is controlled to be started, the operation equipment is activated, and meanwhile, the operation process of all the virtual trainees is supervised to acquire the exercise progress and abnormal feedback of the trainees.
In any mode, a teacher can control the sound of a certain virtual student or an integral student, and control the student to answer in a scene, so that the problem of random question asking of teaching in a teacher course can be solved, and the method is beneficial to ensuring good class order.
And step S05, activating the corresponding target operation equipment according to the teaching mode, collecting the operation information of the target operation equipment in real time, and simultaneously acquiring the interaction information of the virtual user corresponding to the target operation equipment and the virtual operation device, and displaying through the head-mounted VR equipment to complete teaching.
In this embodiment, according to the teaching mode, a corresponding target operation device is activated, and operation information of the operation device is collected in real time; judging whether the operation is abnormal or not according to the operation information; if yes, the corresponding head-mounted VR device is controlled to send an assistance request to the head-mounted VR device of the demonstrator so as to inform the demonstrator of the intervention. Specifically, the step of judging whether the operation abnormality exists according to the operation information includes acquiring an eyeball photo through a head-mounted VR device, judging whether the attention of a person to be taught is not concentrated according to the eyeball photo, wherein the eyeball photo is acquired in real time through the head-mounted VR device, and the eyeballs are identified, if the eyeballs are not identified within a certain continuous time, the fact that the user has a long-time eye closing condition and possibly has a dozing suspicion is indicated, and the corresponding head-mounted VR device can be controlled to send an assistance request to the head-mounted VR device of the demonstrator so as to inform the demonstrator of intervention; if not, acquiring the current operation step of the subject, matching the corresponding operation standard, and judging whether the operation of the subject accords with the operation standard; if not, the corresponding head-mounted VR device can be controlled to send an assistance request to the head-mounted VR device of the demonstrator to inform the demonstrator of the intervention. The intelligent online inspection system has the advantages that the inspection problem of offline teachers is solved by providing the monitoring capability, the offline inspection efficiency is low, the supervision is not complete, no better supervision mode is available, the system supervision capability assists teaching management of the teacher through system supervision in the whole-student exercise process, the teacher can know the exercise progress of each student at the first time, and under abnormal conditions, scene intervention is carried out, auxiliary teaching can be completed at the first time, the exercise efficiency of specific students is improved, the teaching and supervision requirements of teacher classroom exercises are finally solved, and the whole teaching quality is improved.
In the operation process of each subject, the operation data is recorded in real time, and as the corresponding operation standard, namely the sequence of steps, the operation time limit of each step and the like, is formulated for the operation flow in advance, whether the abnormal operation exists or not is judged according to the data recorded in real time and the operation standard. In addition, after the operation of all the educators is finished, the operation steps and the corresponding operation time length in the training process of each virtual educator are respectively obtained, and a data report is generated according to the operation steps and the operation time length and is used for helping the educators to know the teaching condition, wherein the data report comprises training data of each educator and comprehensive training data of all the educators, and through the data report, the user can know which educator has better mastered condition and which operation step is the condition of the ubiquitous problem.
Specifically, when a specific courseware is required to be operated, viewing of virtual action animation is performed through real-time visual data transmission, and in the operation process, people in a virtual environment need to record current operation nodes because of random assignment, so that intervention operation can be performed at any time when the operation nodes are assigned to be operated, students performing the courseware can perform real-time synchronous transmission on data when the students performing the courseware are operated, and other students in a virtual scene can see the latest execution state of real-time update of the courseware to complete teaching. It should be noted that, when the user is operating courseware, the action change of the virtual limbs is supported and displayed, the actual action off line is simulated more vividly and specifically, and better watching experience is finally displayed for students.
It should be noted that, because training is performed in a virtual teaching scene, the method is not limited by a site, each subject has a single virtual courseware to perform operation, in order to be more practical, each subject can control the virtual subjects to walk in the virtual teaching scene to perform communication, watching and learning. In addition, since the virtual teaching subject can be operated to move by the teaching subject, disorder of class order may be caused, and at this time, the virtual teaching subject can be controlled by the teaching subject, namely, the virtual teaching subject is controlled to roam and seat to be fixed in the virtual teaching scene.
In order to achieve the above-mentioned functions, that is, to enable virtual users to move in space and to perform private conversations in a preset area, while other virtual users cannot hear conversations between them, specifically, virtual users are digitized entities created by using virtual reality technology, each virtual user has unique identity and attribute, and can freely move in virtual teaching scenes.
The demonstrator or the educator can create own virtual users and set personalized appearance and attribute for the virtual users, wherein each virtual user has a unique identity identifier for identification and positioning in the virtual teaching scene. Specifically, a coordinate system is firstly constructed, a virtual teaching scene is built on the basis of the coordinate system, after the virtual teaching scene is built, the target positions of virtual objects such as a virtual station, a virtual operation device and the like relative to the edge coordinate positions are determined according to the edge coordinate positions of the virtual teaching scene, meanwhile, a circular area is drawn by taking the center coordinate of a plane view of a overlooking view of the virtual station as a circle center, a preset distance is taken as a radius, boundary coordinates of the circular area are determined, it is required to be explained that the plane view of the overlooking view of the virtual station is that extreme coordinate points in the upper, lower, left and right directions, namely maximum values and minimum values on an x-axis and a y-axis, are determined according to the overlooking view of the virtual station, after the extreme coordinate points are determined, parallel lines with the x-axis are respectively drawn by the upper extreme point and the lower extreme point, parallel lines with the y-axis are respectively drawn by the left extreme point and the right extreme point, and the area enclosed by the four parallel lines is the plane view of the virtual station.
