The Reality-Virtuality Continuum
The Reality-Virtuality Continuum is a concept that states that 100% reality and 100% virtuality lie on opposite ends of a spectrum where any variation of the two sit somewhere in between. Augmented reality is placed closer to the reality end of the spectrum as it is reality augmented by virtuality. The inverse is true for augmented virtuality, it is found near the virtuality end of the continuum. The concept was originally posed by Paul Milgram, a mechanical and industrial engineering professor at the University of Toronto.
Virtual Reality
Virtual Reality, also known as VR, is a computer-generated simulation that an individual in the real world can interact with. A common way for individuals to enter this world is through VR headsets. Headsets can range from the $15 Google Cardboard to the thousand dollar Valve Index. Many headsets also pair with controllers that help the user interact in the virtual world they are in.

Augmented Reality
Augmented Reality, or AR, is the superimposition of virtual graphics on real world visuals in real time. AR comes in many forms but most people may be familiar with things like face filters on Snapchat and Instagram that alter your appearance or display a computer-generated graphic alongside your image. Other apps like Pokemon GO overlay digital images over the real world using the camera on your smart phone.

Mixed Reality
Where VR is an immersive computer generated experience and AR is a virtually enhanced reality, MR or Mixed Reality is an even mix. In MR, the individual can interact with both virtual and physical objects. This is experienced with a headset much like VR but the main difference is that VR doesn’t include the interaction of real world objects.

Extended Reality
Extended Reality is an umbrella term for anything on the Reality-Virtuality Continuum that involves some level of virtuality. AR, VR, and MR are all considered XR because they all involve virtually enhancing reality. The XR industry is predicted to grow exponentially through the next couple of years as we find ways to incorporate it into everyday life.

Immersive Experience Design
Immersive Experience Design is an experience where the user has some form of control over the environment that they are in. This experience can be a story-driven piece of media like films, products or other events. The user would be fully immersed in the experience that they are having through the use of virtual and real visuals and interaction.
