A standardised abstraction layer that provides consistent programmatic interfaces for accessing diverse XR hardware devices — including VR headsets, AR glasses, haptic controllers, eye-tracking modules, and six-DoF tracking systems — enabling cross-platform application development without device-specific code paths. The WebXR Device API (W3C) and OpenXR (Khronos Group) are the primary open standards implementing this abstraction for web and native runtimes respectively.
