Emphasis is placed on participation in the learning process, so that students can actively experience, think and learn, avoid spoon-feeding passive teaching, conduct full-scale simulation display and interaction, increase the practicality and realism of teaching, and enrich the needs of teachers and students for 3D stereoscopic display and practicality. Both of them can not only teach teaching content efficiently, but also use their own core characteristics to subvert the original content and develop into "new content" after the high integration of content and technology.

Difference:

1, VR has high requirements for wearable devices and teaching resources. VR helmets will damage vision, and some students have VR dizziness. Wearing VR devices will isolate teachers.

2.AR has low requirements for resources. For example, ARSeek (Situational Intelligent Teaching System Based on AR) only needs to connect the AR collector to the electronic whiteboard or all-in-one machine, and the participation of teachers and students is also extremely high.
