step two: a virtual scene generation module on a computer (10) generates a virtual classroom scene, the virtual scene generation module generates a virtual blackboard from the content of a handwriting board (14), a teacher writes on the handwriting board (14), the virtual blackboard immediately generates writing content, meanwhile, the virtual scene generation module creates teaching images and teaching sounds of the teacher in real time according to collected teaching audio and video files of the teacher, and a UI module intelligently converts the virtual scene generated by the virtual scene generation module into a virtual classroom suitable for the viewing experience of students;
step three: the student takes AR head to show (1), opens the switch, is connected to the network through the wireless network card on AR head shows (1), gets into virtual classroom, and four sets of stereo camera (4) are broadcast the audio file in virtual classroom in real time on projecting the virtual classroom image that generates to display screen (5), speaker (7) simultaneously, and the student shows (1) through AR head and accomplishes the receipt of course.
