Interactive simulation teaching system of electrical engineering based on virtual reality

The traditional simulation teaching system is limited by the system support software, which cannot realize good interactive teaching. To this end, an interactive simulation teaching system based on virtual reality for electrical engineering is designed. Based on the hardware consisting of ATmega328 chip as the core, sensors and surrounding circuits, the development tool OpenGL is used to draw 3D virtual teaching scenes. The system design is completed by using a double-layer hidden Markov chain to realize simultaneous interactive teaching of multiple paths. The comparison experiment shows that the teaching system has better interactivity, can effectively enhance students' learning interest, and has good user feedback.
