This project is based on augmented reality AR technology and uses the "Internet" system as the cornerstone of subsequent development to develop intelligent teaching aids. The abstract knowledge in the middle school curriculum is superimposed with the virtual model and the real scene by using AR technology, so as to achieve the AR experience effect of perfect combination of reality and virtual. Abstract knowledge is concrete, three-dimensional, game-based learning, and students learn while playing. First of all, with the development of network technology, AR and other emerging technologies have gradually developed and matured, and combined with various traditional industries and emerging industries. Through the elaboration of the advantages of AR technology in the education industry and the future development of AR technology, the development and maturity of AR technology are the trend of the times, and are also the needs of today's and future society, thus demonstrating the emergence and application of AR technology in teaching, the teaching methods are flexible and the classroom is lively and interesting. AR technology is of great significance to the development of education. Secondly, look at the present and future education vision. AR technology is mainly concise in preschool education and middle school education, and pays more attention to the sense of picture and interest, so as to attract children's attention and stimulate children's interest in learning. The future may be even more than we can imagine. Finally, whether in learning or in life, smart teaching aids are topics that can be well applied. While enhancing reality, it will allow learners to understand abstract knowledge, instead of only abstract pictures in previous textbooks., It is difficult to understand, and the advantage of using smart teaching aids is that it can cover up the limitations of traditional education, thereby improving the learning effect of learners.
