Definition and core VR experience

Summary

Virtual reality (VR) is a computer-simulated experience that uses 3D head-mounted displays and pose tracking to make users feel immersed in a virtual world. It typically provides auditory and video feedback, and may also include other sensory effects such as haptic (force) feedback. With VR equipment, users can look around, move within the artificial environment, and interact with virtual objects or features. A core VR experience is built around realistic simulation of a user’s physical presence. This is commonly achieved through VR headsets (a display positioned in front of the eyes) or through multi-projected environments using large screens. VR systems generate stereoscopic 3D visuals and track head movement in real time (including rotational and positional tracking), often supported by motion controllers and other devices (e.g., treadmills or haptic controls) to enable more natural interaction and movement in the virtual space.

Key Points

• 1

  VR is a simulated, immersive experience using 3D head-mounted displays and pose tracking to create a sense of presence in a virtual world.

• 2

  Core VR systems let users look around, move, and interact with virtual objects, using visual/audio feedback and sometimes haptic or force feedback.

• 3

  VR can be delivered via headsets or multi-projected environments, typically rendering stereoscopic 3D graphics with real-time head tracking.
