Classification: CPC G  Y | IPC G

Claim 9:
10. The method of claim 5, wherein step (S6) comprises:
(S6-1) sending information of the screen, the resolution, the aspect ratio and the adapted terminal of the teaching resources to a rendering module on the edge computing server via 5G WIFI/CPE based on the cloud-edge-end network architecture, after the application at the classroom end sends out a rendering request; and after a rendering process is completed by the rendering module, transmitting the information to a local end via a downstream link for viewing by the teacher and student;
(S6-2) calculating a current head posture, viewpoint position and sight direction of the teacher in real time using an observation point-centre point model in graphics, according to the position, the posture and the scaling parameter of the teacher in the virtuality-reality fusion coordinate system determined by the acquisition and processing module, in response to multi-modal interaction behaviors of the teacher to update the screen of the virtual teaching resources on the holographic screen; and
(S6-3) superimposing and displaying a position, a posture and a scaling parameter of a content displayed on the holographic screen in the virtuality-reality fusion coordinate system with the teacher in the teaching activity area; and achieving fusion display of the real teacher and the virtual teaching resources on the holographic screen by combining the head posture, the viewpoint position, the sight direction and the multi-modal interaction behaviors of the teacher.
