VR is currently 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.
The headset tracks the movement of your head and changes the images shown on the display based on it. This process creates the sensation that users are located within the virtual environment. Users of these devices are not only able to experience the computer-simulated environments but also interact with them. Various input methods, from the traditional game controllers and keyboards to the futuristic hand gestures and voice commands, are available or under development.
