IoT Networks and Digital Twin Technology-Based English Classroom Immersive Teaching

In order to improve the effect of English classroom teaching, this paper builds an immersive teaching model of English classroom based on IoT networks and digital twin technology. Moreover, in order to reduce the cost of the system, simplify the system structure, and enable learners to observe the stereoscopic display image with the naked eye, this paper builds an immersive hemispherical projection teaching system, designs the overall structure of the system and various components of the hardware, and studies the projection image predistortion algorithm. In addition, this paper uses the immersive experience between virtual reality technology and immersive teaching as a connection point to design an immersive teaching based on VR and apply it to teaching practice to test the effect of immersive teaching, and perfect the immersive teaching design model based on VR. Finally, this paper designs an experiment to verify and analyze the performance of the system. The experimental results show that the English classroom immersive teaching model based on digital twin technology constructed in this paper is effective.
