Basic versions of the technique are referred to as asynchronous reprojection by Google and Valve, [1] [4] while Oculus has two implementations, called asynchronous timewarp [2] and asynchronous spacewarp. Asynchronous timewarp uses the headset's rotational data to extrapolate a new rendered frame based on the last frame it received.
Tethered – headsets that act as a display device to another device, like a PC or a video game console, to provide a virtual reality experience. Mainstream tethered VR platforms include: SteamVR, part of the Steam service by Valve. The SteamVR platform uses the OpenVR SDK to support headsets from multiple manufacturers, including HTC, Windows

VR headsets are widely used with VR video games , but they are also used in other applications, including simulators and trainers.
During CES 2019 on January 7 HTC announced an upcoming virtual reality headset called Vive Pro Eye featuring eye-tracking and support for foveated rendering. [ 13 ] [ 14 ] In December 2019, Facebook 's Oculus Quest SDK gave developers access to dynamic fixed foveated rendering, allowing the variation in level of detail to be changed on the fly ...
Virtual reality sickness may have undesirable consequences beyond the sickness itself. For example, Crowley (1987) argued that flight simulator sickness could discourage pilots from using flight simulators, reduce the efficiency of training through distraction and the encouragement of adaptive behaviors that are unfavorable for performance, compromise ground safety or flight safety when sick ...
HTC Vive implements "room-scale" virtual reality, whereby a user can walk freely around a play area rather than be constrained to a stationary position. [5] The controllers and headset use a positional tracking system; multiple external base stations are installed in the play area, which each contain an array of LED lights, and two infrared lasers.
