'''Virtual reality''' ('''VR''') is a [[Simulation|simulated]] experience that employs [[3D near-eye display]]s and [[pose tracking]] to give the user an immersive feel of a virtual world. [[Applications of virtual reality]] include entertainment (particularly [[video game]]s), education (such as medical, safety, or military training)<ref>{{Cite web |title=VR Training for Maritime, Renewables & High-Risk Work |url=https://www.3tglobal.com/digital/our-digital-solutions/vr-safety-training/ |access-date=2025-03-25 |website=3t |language=en-GB}}</ref> and business (such as virtual meetings). VR is one of the key technologies in the [[Reality–virtuality continuum|reality-virtuality continuum]]. As such, it is different from other digital visualization solutions, such as [[augmented virtuality]] and [[augmented reality]].<ref>{{cite book |doi=10.1117/12.197321 |chapter=Augmented reality: A class of displays on the reality-virtuality continuum |title=Telemanipulator and Telepresence Technologies |date=1995 |editor-last1=Das |editor-first1=Hari |last1=Milgram |first1=Paul |last2=Takemura |first2=Haruo |last3=Utsumi |first3=Akira |last4=Kishino |first4=Fumio |volume=2351 |pages=282–292 }}</ref>

Currently, standard virtual reality systems use either [[virtual reality headset]]s or multi-projected environments to generate some realistic images, sounds, and other sensations that simulate a user's physical presence in a virtual environment. A person using virtual reality equipment is able to look around the artificial world, move around in it, and interact with virtual features or items. The effect is commonly created by VR headsets consisting of a [[head-mounted display]] with a small screen in front of the eyes but can also be created through specially designed rooms with multiple large screens. Virtual reality typically incorporates [[Auditory feedback|auditory]] and [[video feedback]] but may also allow other types of sensory and force feedback through [[haptic technology]].
