Augmented Reality-Based Interactive Simulation Application in Double-Slit Experiment

Experimental teaching is an essential link in teaching and learning activities, holding an important position in the modern education. However, it is impossible or difficult for some physical phenomena to be carried out in the classroom. With the advantages of portability and combining both the real and virtual world, mobile device and Augmented Reality (AR) technology are having a positive influence on the creating of cognitive tools. In this paper, we develop DSIAR, an AR-based interactive application on mobile devices, to simulate a physical experiment, double-slit experiment. DSIAR allows students to control and interact with a set of 3D models of laboratory apparatus through markers, to change the parameters to observe the dynamic variable phenomenon which is not easy to observe in the real world. The results of pilot testing show that DSIAR can have a positive impact on assisting teaching and learning, attracting students' attention and stimulating their interest, suggesting significant potential for this learning application in practice.
