Virtual Reality, Augmented Reality and Mixed Reality

Virtual Reality

The term 'virtual reality' (VR) refers to a simulated environment in which an interactive computer-generated user experience can take place. It typically uses VR headsets or multi-projected environments, as a means of generating images, sounds and sensations that can simulate a real environment that a user can observe or interact with.

Augmented Reality

Augmented reality (AR) is defined as a live direct or indirect view of a physical, real-world environment whose elements are augmented (or supplemented) by virtual computer-generated sensory input such as sound, video, graphics or GPS data.

Mixed Reality

Mixed reality is a blend of physical and virtual worlds that includes both real and computer-generated objects. The two worlds are "mixed" together to create a realistic environment. A user can navigate this environment and interact with both real and virtual objects.
