Augmented Reality is an interactive mixture between the real world and computerized images that capture the audience’s attention. Devices that support augmented reality improve the image of the real-world surroundings with simulated physical input such as sound, video, or graphics overlaid on top of the real-world view. In recent years, augmented reality has improved beyond expensive military applications and has now entered a wide variety of domains. In engineering education, AR technologies can serve as a learning aid as well as a basis for innovation. The technology provides 3-D visualizations that allow to: (i) observe flaws in designs before the building process starts; (ii) see phenomena that are invisible to the naked eye, such as electromagnetic fields; (iii) incorporate features of the real world, machinery, facilities, etc. We present a mobile application that aims to be an aid for students in the course EMT1240 Introduction to Computer Engineering Technology. Our mobile app makes use of AR technologies to enhance learning about electrical circuits by bringing alive some of the diagrams in the lab manual of the class. It provides animated 3D models where students can play and experiment, to understand how to use basic components in the circuits’ diagrams work and the relationship between voltage, resistance, and current.
