VR: Computer-generated stereo visuals which entirely surround the user, entirely replacing the real-world environment around them.
AR: Augmented reality is the overlaying of digitally-created content on top of the real world. Augmented reality – or ‘AR’ – allows the user to interact with both the real world and digital elements or augmentations.
MR: A mixed reality experience is one that seamlessly blends the user’s real-world environment and digitally-created content, where both environments can coexist and interact with each other.
XR: Technology-mediated experiences that combine virtual and real-world environments and realities. XR covers the hardware, software, methods, and experience that make virtual reality, mixed reality, augmented reality, cinematic reality, and others a reality.
