The virtuality continuum is a continuous scale ranging between the completely virtual, a virtuality, and the completely real, reality. The reality–virtuality continuum therefore encompasses all possible variations and compositions of real and virtual objects. It has been described as a concept in new media and computer science.
Augmented reality ( AR) is an interactive experience that combines the real world and computer-generated 3D content. The content can span multiple sensory modalities, including visual, auditory, haptic, somatosensory and olfactory. [1] AR can be defined as a system that incorporates three basic features: a combination of real and virtual worlds ...
Virtual reality ( VR) is a simulated experience that employs 3D near-eye displays and pose tracking to give the user an immersive feel of a virtual world. Applications of virtual reality include entertainment (particularly video games ), education (such as medical, safety or military training) and business (such as virtual meetings).
The augmented reality technology included a headset with a display the doctors could see through to the person. It allowed them to project images from X-rays or CT scans, for example, onto the ...
Virtual reality headset. A virtual reality headset (or VR headset) is a head-mounted device that uses 3D near-eye displays and positional tracking to provide a virtual reality environment for the user. VR headsets are widely used with VR video games, but they are also used in other applications, including simulators and trainers.
Extended reality. Extended reality ( XR) is an umbrella term to refer to augmented reality (AR), virtual reality (VR), and mixed reality (MR). The technology is intended to combine or mirror the physical world with a " digital twin world" able to interact with it, [1] [2] giving users an immersive experience by being in a virtual or augmented ...
Virtual reality exposure therapy (VRET) is a form of exposure therapy for treating anxiety disorders such as post traumatic stress disorder (PTSD) and phobias. Studies have indicated that combining VRET with behavioral therapy, patients experience a reduction of symptoms. [15] [16] In some cases, patients no longer met the DSM-V criteria for PTSD.
The Sword of Damocles is widely misattributed as the name of the first AR (or VR) display prototype. According to Ivan Sutherland, this was merely a joke name for the mechanical system that supported and tracked (using attached wires) the actual HMD below it. [1] It happened to look like a giant overhead cross, hence the joke.
