Virtual reality (VR) replaces a person’s surroundings entirely with a computer-generated environment, experienced through a head-mounted display and designed to create the sensation of being physically present in that simulated world. Because nothing of the physical room remains visible, VR is the most fully immersive point on the XR spectrum. Sources: Unity Glossary; XRSI Standard… Read more

Virtual surgery creates realistic simulations of medical procedures using accurate anatomical models and physics-based tissue behaviour, so practitioners can train for and plan complex operations in a risk-free environment with haptic feedback and performance tracking.

Virtual training creates safe, repeatable environments that simulate real-world scenarios, allowing learners to practise without real-world consequences while receiving immediate feedback and performance tracking. Source: Unity Glossary Read more

Volumetric video captures a three-dimensional representation of a real space or subject, including depth information, so viewers can move within the captured scene and view it from any angle rather than from a single fixed viewpoint.

The WebXR family refers to the web standards that deliver immersive content through a browser without installing an application. WebGL renders hardware-accelerated 2D and 3D graphics in the browser, while WebAR and WebVR provide browser-based augmented and virtual reality experiences. The practical appeal is removing the software-installation barrier. Sources: Unity Glossary: WebGL; WebAR; WebVR Read more

XR data is the data collected, inferred, processed, and shared from both users and bystanders in order to create immersive experiences. The explicit inclusion of bystanders is what distinguishes it from most consumer data categories. Source: XRSI Standard XR Definitions (XR-001) Read more
