Exploration of Interactive Teaching Models Integrating Augmented Reality Technology in University Science and Technology Parks

Abstract

Augmented reality technology is regarded as one of the modern information technologies that are most likely to change education and is widely used in education and teaching by virtue of its virtual, visual, and interactive features. In this paper, the skin color model and background model are used to recognize gestures in complex backgrounds during interactive teaching, and the optical flow features of the corner and edge points of the gesture image are extracted by the Harris method to recognize the occlusion gestures in interactive teaching. On this basis, the interactive teaching platform integrating augmented reality technology is established by combining the gesture recognition method with Unity 3D and EasyAR systems. After one semester of teaching in a university science and technology park, the average grades of the students in the experimental class applying the interactive teaching mode and the control class in the traditional multimedia teaching mode are significantly different (P=0.001<0.05). Students learning attitudes after the teaching experiment are significantly different from their learning attitudes before the teaching experiment. The teaching mode designed in this paper is of great significance for teaching and has a wide range of application prospects and use value in the field of education, and the optimization strategies proposed from the AR context design and other aspects lay the foundation for stimulating students’ interest in learning and improving the efficiency and effectiveness of teaching.
