XR

XR is an umbrella term that includes the following types of applications:

Virtual Reality (VR): The application simulates a self-contained environment around the user.
Mixed Reality (MR): The application combines its own environment with the user’s real-world environment and allows them to interact with each other.
Augmented Reality (AR): The application layers content over a digital view of the real world.

The span between VR to AR is a continuum, with MR falling somewhere in the middle, depending on the capabilities of a particular device and the intent of your application.
