What is Virtual Reality?Virtual reality is the creation of a computer modelled 3d world or environment, presented to you through a specialised headset, which gives the strong immersive feeling of actually being in that world. The headset contains two small (but high resolution) stereoscopic screens presented to you, to give the 3d appearance.

What is Augmented Reality?AR is all about bringing digital information and overlaying it over the real environment. The only difference from VR is that it creates a totally artificial environment around you, whereas AR uses the environment around you and overlays the digital information over it. For VR, you will require a VR device, but for AR it can be achieved by simply using a smartphone, tablet, or dedicated VR devices
What is Mixed Reality?Think of MR as a hybrid of VR and AR. Using MR, a user can view the real world just like in AR, but can also view virtual objects as in VR. The difference with MR is that those virtual objects are referenced or anchored with the real space. That means that the virtual object is interacting within the real world.
