Augmented Reality (AR) is the process of layering real-time information over real world environments. Virtual Reality (VR) is completely immersive and places the viewer in an alternate reality. Both of these technologies require active participation by the users. AR actually requires walking and moving in and out of real spaces while VR uses head tracking (and the optional controllers) to interact.
