AR is a new type of multimedia computer technology, which integrates pattern recognition technology, machine learning technology, multimedia reality technology and 3D modeling technology to create an intelligent, interactive, immersive system combining virtual and real. The design of experiential teaching software for computer specialty provides strong support for the application and dissemination of AR technology. It can create an assembled development environment according to actual needs, extend and stretch the software development environment currently used, and intuitively display the software development process with the help of various types of modeling components. The users needn't purchase or construct a large-scale application environment. The virtual world and the real world are seamlessly linked so as to improve the learning efficiency of students in the Open University of China.
