~~==Introduction==~~

'''Virtual Reality''' ('''VR''') is a computer-simulated artificial multisensory 3D environment that can mimic the properties and imagery of the physical world, be completely based in fantasy, or a mix of both. It involves technology that uses computer-generated environments to simulate a physical presence in a virtual world. The system uses position-tracking and responds to the user’s inputs. In VR, the senses are temporarily fooled into believing that the artificial environment is real. The goal of a true VR experience is to create [[presence]] - the feeling of physically being somewhere else, of being in another reality <ref name=”0”> Bierbaum, A.D. (2000).

'''Virtual Reality''' or '''VR''' is a computer-simulated artificial ~~world~~ that can mimic the physical ~~features~~ of ~~the~~ environments in ~~real life~~ and ~~in fantasy~~. In VR, ~~all of our~~ senses are fooled~~, temporarily,~~ into believing that ~~this~~ artificial environment is real. The goal of a true VR experience is to create [[presence]], the feeling of physically being somewhere else, being in another reality.

Virtual Reality is an interactive and immersive medium that can be ~~utilized~~ to create unique experiences that are unattainable elsewhere. VR has the power to transform [[games]], [[films]] and other forms of media. Some enthusiasts call VR the "ultimate input/output device" or the "last medium" because any subsequent medium can be created within VR, using only software.

While [[Augmented Reality]] enhances the real world with digital content, Virtual Reality completely replaces the real world with a virtual one, creating a brand new digital environment for the users to explore.

==Main characteristics==

'''Interactive -''' The user’s input controls the system and guides the behavior of the VR experience, while also modifying the virtual environment. This type of interaction engages the user, connecting him to the application in a more natural way since the environment responds directly to the stimuli <ref name=”0”></ref>.

'''Immersive -''' An immersive experience has to provide a sense of presence as well as a sense of engagement. Immersion can be divided into three different aspects:

'''1.''' According to Bierbaum (2000), “For a VR application to be immersive, it must be perceptually immersive by providing ‘the presentation of sensory cues that convey perceptually to users that they’re surrounded by the computer-generated environment.’” Therefore, the VR must provide the user with an all-encompassing sensory input <ref name=”0”></ref>.

'''2.''' The second aspect of immersion is the sense of presence. This implies that the VR experience must give the user the sense they are “in” the virtual world <ref name=”0”></ref>.

'''3.''' The final aspect is engagement. It is the degree “to which the user has a sense they are deeply involved in the environment.” <ref name=”0”></ref>

'''Multisensory -''' providing a virtual experience that uses multiple human sensory systems increases the level of immersion. While current VR systems cannot provide a full range of stimuli to all human senses, it is expected that in the future this problem will be solved and the VR experience will be completely or almost indistinguishable from reality. The more senses are involved in the VR experience, the higher the degree of engagement and, consequently, this results in a greater sense of presence <ref name=”0”></ref>.

'''Synthetic -''' The environment is artificial, created by a computer in real-time <ref name=”0”></ref>.
