The use of graphics, sound and input technology in video games can be incorporated into VR. Several Virtual Reality head mounted displays (HMD) were released for gaming during the early-mid 1990s.
These included the Virtual Boy developed by Nintendo, the iGlasses developed by Virtual I-O, the Cybermaxx developed by Victormaxx and the VFX1 Headgear developed by Forte Technologies. Other modern examples of narrow VR for gaming include the Wii Remote, the Kinect, and the PlayStation Move/PlayStation Eye, all of which track and send motion input of the players to the game console somewhat accurately. Several companies were working on a new generation of VR headsets, which were released on March 28, 2016: Oculus Rift is a head-mounted display for gaming purposes developed by Oculus VR, an American technology company that was acquired for US$2 billion by Facebook in 2014.
One of its rivals was named by Sony as PlayStation VR (codenamed Morpheus), which requires a PS4 instead of a PC to run. In 2015, Valve Corporation announced their partnership with HTC to make a VR headset capable of tracking the exact position of its user in a 4.5 by 4.5 meters area, the HTC Vive.
All these virtual reality headsets are tethered headsets that use special lenses to magnify and stretch a 5.7-inch screen (in the case of Morpheus) across the field of vision. There are more gaming VR headsets in development, each with its own special abilities. StarVR offers a 210° field of view, whereas FOVE tracks the position of human eyes as an input method.
