AR combines three-dimensional (3D) computer-generated objects and text superimposed on real-life images and videos, all in real time. RA complements the reality rather than replacing it completely. The AR allows children to manipulate virtual objects with hands, and these objects are added to the real environment. AR pedagogy has multiple applications because it allows to add visual and interactive information to an initial content. To be able to experience AR, the device used must have a screen to display the combinaison of virtual and real and a camera to capt the real.
