Design of Ethnic Language Learning Assistance System Based on Augmented Reality (AR) Technology

In order to address the shortcomings of the current ethnic language teaching system, the author proposes an ethnic language learning assistance system based on augmented reality (AR) technology. The author conducted research and implementation on an interactive augmented reality teaching assistance system based on the B/S architecture (Browser/Server). Among them, in-depth research has been conducted on human hand target detection and tracking technology for monocular cameras, achieving real-time interaction between human hands and virtual 3D models; This system uses the Web technology of augmented reality technology and Internet technology to complete the construction of the system. The test results indicate that: The author conducted multi model testing and recorded the success rate of virtual fusion and human-computer interaction performance. According to the test results, the accuracy of the system for human- computer interaction is about 90%, which can meet the user's needs for 3D model interaction. The average response time of this system in traditional methods is around 126ms, while in this method, the average response time is around 96ms, and the average difference between the two is around 31ms. Conclusion: The system can achieve the design requirements goals.
