Augmented reality allows users to interact with the real environment through a mobile display (smartphone, PC, tablet, etc.), which shows, once framed, the “augmented” physical world, or enriched with certain visual information. Doing AR training allows users to learn and put into practice what they already know or what they want to better understand and put into practice in realistic environments. agile and engaging learning. Then think of the use of AR in the case of guided maintenance or safety training courses, imagining for example how to deal with the danger of fire. Virtual reality, on the other hand, is a simulation of reality made possible thanks to information technology. The user can explore a virtual environment and can interact through specific devices: 3D viewer, headphones and other dedicated solutions. Unlike augmented reality which precisely “increases” the perception of the world with a series of digital content, virtual reality isolates the user from the external environment by transporting him into a parallel reality. This is why we talk about immersive virtual reality as we “immerse ourselves” in an active learning environment at 360 degrees, experimenting with images and sounds that dissolve the barrier between virtual and real. Using the tools, students watch, talk and move freely in a 3D virtual environment, interacting with tools, machinery and other simulated real students and instructors. Virtual reality is especially ideal in cases where complex or critical situations such as working in dangerous contexts have to be simulated and become much more practical, economical and safe in an immersive simulation. Companies that use VR technology instead of traditional methods to teaching employees are finding that their employees learn faster and retain more information after training
