Application of VR and AR Technology in Fish Simulation Teaching

In view of the shortage of fish teaching experimental objects, the shortage of experimental places, and the shortage of funds, a fish simulation teaching platform is constructed. With the help of AR, VR and AI technology, the multi-modal learning mode of VR end, PC end and mobile end is realized, and the repeated virtual operation is realized through VR technology, which comprehensively and clearly shows the anatomical structure of fish, the adjacent internal organs and the spatial position relationship of fish Through AR technology, the knowledge content is displayed on the mobile end, so that learning is not limited by time and space, and the learning content is vivid. The system sets up different teaching links such as simulation demonstration, repeated training, examination evaluation, etc., and integrates the key points and difficulties of knowledge into virtual teaching. The practical application results show that the system can solve the problem of lack of experimental objects, give students easy and fast learning experience, and stimulate students' interest in learning. It can be used for reference to explore the application of AR / VR technology in fish simulation teaching.
