Augmented reality (AR) technology software is becoming increasingly popular and more closely integrated with human life. Particularly in the field of education, AR has brought about a breakthrough in teaching methods, introducing a new approach for both learners and educators. Instead of rote learning and abstract theories, AR enables learners to engage in practical learning experiences, interact with 3D models, and access augmented information, making lessons more realistic, detailed, understandable, and memorable. This approach captivates learners and yields significantly higher effectiveness compared to traditional methods. Therefore, in this paper, we present the process of developing an augmented reality application in education, illustrated through an English vocabulary teaching application.
