Using 360 degree tracking equipment such as infrared sensors, the VR system monitors the user's movement in all directions, and translates this into the virtual world in real-time.
[1] This allows the player to perform tasks, such as walking across a room and picking up a key from a table, using natural movements.
In contrast, a stationary VR experience might have the player navigate across the room using a joystick or other input device,[2] which may cause motion sickness.
[3] Its SteamVR tracking technology is developed by Valve and allows areas up to 10 m x 10 m.[4] The Oculus Rift VR system was introduced primarily for front facing 180 degree experiences.
However, Oculus now supports two sensor diagonal placement roomscale or users can purchase a third sensor to enable more robust room-scale tracking,[5] Room-scale experiences require a large amount of empty space for the player to walk around without the risk of bumping into real-life obstacles.
