Abstract-In order to solve the problem of lack of immersion in the MOOC curriculum, through research on key technologies, a MOOC teaching interactive system based on virtual reality was constructed to improve it. Through the decomposition of complex objects or the addition of blank sub-objects, the system built corresponding collision detectors to achieve more realistic collision detection effects. The immersive and interactive nature of the virtual user in the virtual scene was enhanced. The results showed that the system used the immersive, interactive and constructive sense of virtual reality to build people's interest in learning. Therefore, the MOOC teaching interactive system based on virtual reality has a good sense of immersion, interaction and conceivability.Keywords-virtual reality; MOOC teaching; interactive system; 3D modeling
IntroductionWith the development of communication technology and the increasing popularity of communication infrastructure, distance learning based on network multimedia has become the best way to satisfy people's lifelong learning needs. To cater to people's ever-increasing demand for learning content, such as diversification and globalization, and the time awareness, the massive online open course (MOOC) learning mode was developed with the micro-course as a unit has emerged. MOOC provides the same platform for lifelong learning for people with different regions, cultures, and economic levels. It opened the door for more people to experience the higher learning that had been left behind by many people. Anyone can register and log on to the MOOC education platform via the Internet and choose any MOOC course that they are interested in. After learning, they obtain the certificate of the course through corresponding examination. MOOCs are rapidly sought after by people for their free, open and unrestricted features. The number of students participating in MOOCs worldwide and the number of universities are all increasing. With the rapid development of MOOCs, their shortcomings have become increasingly prominent. Although it satisfies the people's desire for knowledge, the boring network teaching model makes the learning iJET
