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, education and business. VR is one of the key technologies in the reality-virtuality continuum. As such, it is different from other digital visualization solutions, such as augmented virtuality and augmented reality.
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. AR can be defined as a system that incorporates three basic features: a combination of real and virtual worlds, real-time interaction, and accurate 3D registration of virtual and real objects. The overlaid sensory information can be constructive, or destructive. As such, it is one of the key technologies in the reality-virtuality continuum.
A volumetric display device is a display device that forms a visual representation of an object in three physical dimensions, as opposed to the planar image of traditional screens that simulate depth through a number of different visual effects. One definition offered by pioneers in the field is that volumetric displays create 3D imagery via the emission, scattering, or relaying of illumination from well-defined regions in (x,y,z) space.
Mark Bolas is a Professor of Interactive Media in the USC Interactive Media Division, USC School of Cinematic Arts at the University of Southern California, Director of their Interactive Narrative and Immersive Technologies Lab, Director of Mixed Reality Laboratory at USC's Institute for Creative Technologies, and chairman of Fakespace Labs in Mountain View, California.

Fulldome refers to immersive dome-based video display environments. The dome, horizontal or tilted, is filled with real-time (interactive) or pre-rendered (linear) computer animations, live capture images, or composited environments.
Eric Mayorga Howlett was the inventor of the LEEP, extreme wide-angle stereoscopic optics used in photographic and virtual reality systems.
In virtual reality (VR), immersion is the perception of being physically present in a non-physical world. The perception is created by surrounding the user of the VR system in images, sound or other stimuli that provide an engrossing total environment.
A projection augmented model is an element sometimes employed in virtual reality systems. It consists of a physical three-dimensional model onto which a computer image is projected to create a realistic looking object. Importantly, the physical model is the same geometric shape as the object that the PA model depicts.
Foveated imaging is a digital image processing technique in which the image resolution, or amount of detail, varies across the image according to one or more "fixation points". A fixation point indicates the highest resolution region of the image and corresponds to the center of the eye's retina, the fovea.
Niko Bolas is an American music producer, sound engineer, and consultant. He is also a business developer in the fields of virtual reality and Internet radio. In 1989, Bolas founded Fakespace Music with Mark Bolas, Ian McDowall, and Christian Greuel. In 1995, Fakespace developed the Soundsculpt Toolkit, a software interface which lets music communicate with graphical elements of virtual reality.
In computing, 3D interaction is a form of human-machine interaction where users are able to move and perform interaction in 3D space. Both human and machine process information where the physical position of elements in the 3D space is relevant.
Crystal River Engineering Inc. was an American technology company best known for their pioneering work in HRTF based real-time binaural, or 3D sound processing hardware and software. The company was founded in 1989 by Scott Foster after he received a contract from NASA to create the audio component of VIEW, a virtual reality based training simulator for astronauts. Crystal River Engineering was acquired by Aureal Semiconductor in 1996.
Oculus Rift is a discontinued line of virtual reality headsets developed and manufactured by Oculus VR, a virtual reality company founded by Palmer Luckey that is widely credited with reviving the virtual reality industry. It was the first virtual reality headset to provide a realistic experience at an accessible price, utilizing novel technology to increase quality and reduce cost by orders of magnitude compared to earlier systems. The first headset in the line was the Oculus Rift DK1, released on March 28, 2013. The last was the Oculus Rift S, discontinued in April 2021.
Reality Labs, formerly Oculus VR, is a business and research unit of Meta Platforms that produces virtual reality (VR) and augmented reality (AR) hardware and software, including virtual reality headsets such as the Quest, and online platforms such as Horizon Worlds. In June 2022, several artificial intelligence (AI) initiatives that were previously a part of Meta AI were transitioned to Reality Labs. This also includes Meta's fundamental AI Research laboratory FAIR which is now part of the Reality Labs - Research (RLR) division.
Windows Mixed Reality (WMR) is a discontinued platform by Microsoft which provides augmented reality and virtual reality experiences with compatible head-mounted displays.
A virtual reality 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. VR headsets typically include a stereoscopic display, stereo sound, and sensors like accelerometers and gyroscopes for tracking the pose of the user's head to match the orientation of the virtual camera with the user's eye positions in the real world. Augmented reality (AR) headsets are VR headsets that enable the user to see and interact with the outside world. Examples of AR headsets include the Apple Vision Pro and Meta Quest 3.
GameFace Labs is an American technology company that develops hardware and software for the consumer virtual reality market, and was founded in 2013 by Edward Mason. The company's headquarters are in San Francisco, with international offices in London, United Kingdom.
A virtual reality game or VR game is a video game played on virtual reality (VR) hardware. Most VR games are based on player immersion, typically through a head-mounted display unit or headset with stereoscopic displays and one or more controllers.
The first-generation Oculus Quest is a discontinued virtual reality headset developed by Oculus, a brand of Facebook Inc., and released on May 21, 2019. Similar to its predecessor, Oculus Go, it is a standalone device, that can run games and software wirelessly under an Android-based operating system. It supports positional tracking with six degrees of freedom, using internal sensors and an array of cameras in the front of the headset rather than external sensors. The cameras are also used as part of the safety feature "Passthrough", which shows a view from the cameras when the user exits their designated boundary area known as "Guardian". A later software update added "Oculus Link", a feature that allows the Quest to be connected to a computer via USB, enabling use with Oculus Rift-compatible software and games.
The Meta Quest Pro is a mixed reality (MR) headset developed by Reality Labs, a division of Meta Platforms.
