Cross Reality (XR) is the umbrella term for the following three technologies: augmented reality, virtual reality and mixed reality. Augmented reality is a computer-supported perception or representation that adds virtual aspects to the real world. Augmented reality (AR) integrates digital objects into the real world.
Virtual reality, VR for short, is the representation and simultaneous perception of reality and its physical characteristics in a real-time computer-generated, interactive virtual environment. VR creates a virtual world with digital objects, landscapes and people. The reality is completely hidden.
Mixed Reality is the term used to describe environments or systems that mix the natural perception of a user with an artificial (computer-generated) perception.
