The term Augmented Reality (AR) refers to the technologies that superimpose digital content generated by computers over the user’s view of the real world. AR technologies enhance the version of the physical environment with computer-generated sensory input such as sound, video, or graphics overlaid on top of the real-world view. In recent years, AR has moved 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 mobile app that uses different approaches of AR. Our app aims to enhance learning about electrical circuits, in particular learning about breadboards, series circuits, and parallel circuits.
