# WebXR Blink Module
_For a more thorough/high level overview of the entire WebXR stack, please refer to
[components/webxr][components-webxr-readme]_

The WebXR API enables Virtual Reality (VR) and Augmented Reality (AR) features on the Web.

WebXR and its associated modules are developed by the Immersive Web W3C
[Working Group][working-group] and [Community Group][community-group].

This Blink module implements the "core" [WebXR Device API][webxr-spec], as well as the following
WebXR modules:

 - [Gamepads][gamepads-spec]
 - [Augmented Reality][ar-spec]
 - [Hit Test][hit-test-spec]
 - [DOM Overlays][dom-overlays-spec]
 - [Anchors][anchors-spec]
 - [Lighting Estimation][lighting-spec]
 - [Hand Input][hand-input-spec]
 - [Layers][layers-spec]
 - [Depth Sensing][depth-spec]
 - [Plane Detection][plane-spec]

The Blink implementation communicates with the browser process using the
`VRService` [Mojo interface][mojom-readme]. The browser process (implemented in
[content/browser/xr/][browser-readme]) then coordinates with the low-level
device runtimes (implemented in [device/vr/][device-readme]) to support
the WebXR features.
