Developing a Simple and Cost-Effective Markerless Augmented Reality Tool for Chemistry Education

Traditional visualization methods have a limited capacity to enhance students' understanding of 3D molecular structure and reactivity. Studies have shown that 3D visualization tools can play an essential role in improving students' learning. Augmented reality (AR) is a technology that merges virtual objects with real-world images seamlessly. We have previously developed a "marker-based" AR app (ARchemy) for Android devices to help students visualize molecular structures in 3D. Using recent technological advancements, to avoid the limitation of using a printed marker, we have successfully developed a simple and low-cost "markerless" AR app, which can be used for both Android and iOS devices. Students who used the AR app saw a significant increase in understanding of the complexity of molecular structures compared to those who used traditional molecular modeling kits. This unique technology will not only help teachers create more interactive and engaging lessons but also benefit students by making it more accessible and cost-effective to access the resources from any place and at any time.
