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.
The Holodeck is a fictional device from the television franchise Star Trek which uses "holograms" to create a realistic 3D simulation of a real or imaginary setting, in which participants can freely interact with the environment as well as objects and characters, and sometimes a predefined narrative.
A cave automatic virtual environment is an immersive virtual reality environment where projectors are directed to between three and six of the walls of a room-sized cube. The name is also a reference to the allegory of the Cave in Plato's Republic in which a philosopher contemplates perception, reality, and illusion.
Mixed reality (MR) is a term used to describe the merging of a real-world environment and a computer-generated one. Physical and virtual objects may co-exist in mixed reality environments and interact in real time.
A head-mounted display (HMD) is a display device, worn on the head or as part of a helmet, that has a small display optic in front of one or each eye. HMDs have many uses including gaming, aviation, engineering, and medicine.
Annastacia Palaszczuk is an Australian politician who served as the 39th premier of Queensland from 2015 to 2023.

Immersion into virtual reality (VR) 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.
Virtuality was a range of virtual reality machines produced by Virtuality Group, and found in video arcades in the early 1990s. The machines delivered real-time VR gaming via a stereoscopic VR headset, joysticks, tracking devices and networked units for a multi-player experience.
Euclideon Pty Ltd is an Australian computer software company known for a middleware 3D graphics engine, called Unlimited Detail. Euclideon is also the parent company and operator of Holoverse, a 'holographic entertainment centre' located on the Gold Coast, in Queensland, Australia. Euclideon claims that Unlimited Detail is based on a point cloud search engine indexing system and that the technology can provide 'unlimited graphics power', proposing it as a replacement for polygon-based rendering.
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.
An optical head-mounted display (OHMD) is a wearable device that has the capability of reflecting projected images as well as allowing the user to see through it. In some cases, this may qualify as augmented reality (AR) technology. OHMD technology has existed since 1997 in various forms, but despite a number of attempts from industry, has yet to have had major commercial success.
zSpace is a technology firm based in San Jose, California that combines elements of virtual and augmented reality in a computer. zSpace mostly provides AR/VR technology to the education market. It allows teachers and learners to interact with simulated objects in virtual environments.
A virtual concert, also called V-concert or virtual live, refers to a performance in which the performers are represented by virtual avatars. Virtual concerts can take place in real life, where digital representations of the performers are projected in on stage, or within fully digital virtual worlds. Real life concerts are popular in South Korea, where performances by groups such as Girls' Generation have attracted thousands of fans. Performers in virtual concerts may represent real individuals, but can also be entirely fictitious characters like Hatsune Miku.
A stereoscopic video game is a video game which uses stereoscopic technologies to create depth perception for the player by any form of stereo display. Such games should not be confused with video games that use 3D game graphics on a mono screen, which give the illusion of depth only by monocular cues but lack binocular depth information.
castAR was a Palo Alto–based technology startup company founded in March 2013 by Jeri Ellsworth and Rick Johnson. Its first product was to be the castAR, a pair of augmented reality and virtual reality glasses. castAR was a founding member of the nonprofit Immersive Technology Alliance.
Windows Mixed Reality (WMR) is a discontinued platform by Microsoft which provides augmented reality and virtual reality experiences with compatible head-mounted displays.
Microsoft HoloLens is an augmented reality (AR)/mixed reality (MR) headset developed and manufactured by Microsoft. HoloLens runs the Windows Mixed Reality platform under the Windows 10 operating system. Some of the positional tracking technology used in HoloLens can trace its lineage to the Microsoft Kinect, an accessory for Microsoft's Xbox 360 and Xbox One game consoles that was introduced in 2010.
EON Reality is a multinational virtual reality and augmented reality software developer headquartered in Irvine, California. The company was founded by Dan Lejerskar, Mikael Jacobsson and Mats W. Johansson in 1999. Its clients include Boeing, Microsoft, Lexus and Cornell University.
A virtual reality game or VR games is a video game played on virtual reality (VR) hardware. Most VR games are based on player immersion, typically through head-mounted display unit or headset with stereoscopic displays and one or more controllers.
