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. Developers often refer to MR apps as passthrough apps, because many MR headsets use passthrough cameras to display a live view of the real world.
- Augmented Reality (AR): The application layers content over a view of the real world.
The span between virtual to augmented reality is a continuum, with mixed reality falling somewhere in the middle, depending on the capabilities of a particular device and the intent of your application.
