Many undergraduate students find it difficult to visualize 3D concepts in physics and engineering courses. There is a need for context-specific spatial visualization activities to help students connect 2D representations to 3D models. We have assembled an interdisciplinary team of undergraduate physics and computer science research students and faculty to create 3D augmented reality (AR) models of physics concepts including centripetal force, torque, electric and magnetic fields and forces, and electromagnetic induction. Utilizing software including Unity, Vuforia, and Merge SDK, research students create the 3D physics models. Once developed, researchers upload the AR apps to the Apple and Android stores, making them publicly available. To use, students download the apps to their smartphone or tablet and view the Merge cube through their device, the 3D physics model appears on the Merge cube. By rotating the Merge cube, the students can view the 3D model from different perspectives. This provides an opportunity for students to envision many 2D representations of the same 3D concept. Students and instructors can utilize these AR apps in a variety of situations including for use within lectures, problem-solving sessions, or labs, either within in-person or remote instruction. Augmented reality 3D models have applications in STEM disciplines including mathematics and chemistry where strong spatial visualization improves student performance in STEM.
