This paper considers the issue of human subjectivity in the system of “5G + AI+Education” from the perspective of, on the one hand, the real need for the problems that gradually emerge in the new round of development and application of artificial intelligence, and a philosophical reflection on the application of artificial intelligence in specific fields, on the other hand. It is also a further examination of the issue of human subjectivity in the new context. On the other hand, it is also a further examination of the issue of human subjectivity in the new context of the times, which can also provide students with an immersive learning environment, and AI artificial intelligence and hologram technology can enhance students’ motivation. This paper shows the specific steps and implementation measures of “5G” technology into online oral teaching and provides a case study design to explore the new online oral teaching model, summarizing the advantages and proposing solutions to the shortcomings. The system visualizes each step of gesture recognition to facilitate students’ understanding. Students can experience the process of gesture recognition according to the guidance of the interactive interface, and then, the complex and abstract gesture recognition process is explained with a figurative example, which is conducive to primary and secondary school students’ deeper understanding and improved logical thinking. This will help primary and secondary school students to have a deeper understanding and improve their logical thinking skills. Finally, a comparison experiment is designed to verify the effectiveness of using this system to learn AI knowledge compared with traditional learning methods. The experimental results are analyzed to prove that using this system to learn AI knowledge is effective and helps improve users’ interest in learning and hands-on ability.
