XR, VR, AR, MR: What;s the difference?

Extended Reality (XR) refers to all real-and-virtual environments generated by computer technology and wearables. The 'X' in XR is a variable that can stand for any letter.

Virtual Reality (VR) encompasses all immersive experiences. These could be created using purely real-world content (360 Video), purely synthetic content (Computer Generated), or a hybrid of both.

Augmented Reality (AR) is an overlay of computer generated content on the real world that can superficially interact with the environment in real-time. With AR, there is no occlusion between CG content and the real-world.

Mixed Reality (MR) is an overlay of synthetic content that is anchored to and interacts with objects in the real world—in real time. Mixed Reality experiences exhibit occlusion, in that the computer-generated objects are visibly obscured by objects in the physical environment.
