LTI Extended Reality (XR)

Extended reality (XR) is an umbrella term for any technology that alters reality by adding digital elements to the physical or real-world environment to any extent and includes, but is not limited to, augmented reality (AR), mixed reality (MR), and virtual reality (VR).

Any new technology that blends the physical and virtual worlds will also be categorized as XR. The “X” in XR stands for any variable—any letter of the alphabet—that may be used in the future for such technologies.

Therefore, the term extended reality does not refer to any specific technology; it includes any existing or new technologies that may be created in the future that alter reality, either by blending the digital and the physical world or by creating a fully virtual environment.
