VR is | VR is created by '''[[head-mounted display]]s''' (HMDs) such as the [[Oculus Rift]]. HMDs utilize [[stereoscopic displays]] and specialized [[lenses]] along with [[#Motion Tracking|motion tracking hardware]] to give the illusion that the user is physically inside the virtual world. | ||
To create the illusion of depth, a display is placed very close to the users' eyes, covering their entire field of view. Two images that are very similar but have different perspectives are channeled into each eye to create [[parallax]], the visual phenomenon where our brains perceive depth based on the difference in the apparent position of objects. | To create the illusion of depth, a display is placed very close to the users' eyes, covering their entire field of view.
