Research on interactive augmented reality-based solid geometry teaching assistant system

Abstract

Two-dimensional textbook cannot show the three-dimensional effect of solid geometry. For many middle school students who lack three-dimensional space thinking, a teaching assistance system that can vividly display three-dimensional geometry and interact with it is essential. In recent years, the introduction of augmented reality technology into education and teaching has attracted much attention from the industry. However, the existing augmented reality teaching assistance system either does not support interaction, resulting in poor teaching effect; Or they need to wear VR devices to achieve interaction, resulting in excessive physical burden on students and affecting the learning experience; Or an app-based approach, which requires downloading before it can be used, is difficult to widely serve students. In response to the above problems, this paper completed the system design by combining web technology and augmented reality technology, and realized real-time interaction between human hands and virtual three-dimensional geometry, solving the problem of weak interactivity of traditional augmented reality teaching assistance systems. Finally, through a questionnaire survey, the user experience of this system is compared with that of traditional textbooks, and the results show that this system has a better learning experience.
