WebXR Device API (commonly known as WebXR) is a Web API developed by the World Wide Web Consortium (W3C) that provides interfaces for accessing virtual reality (VR) and augmented reality (AR) devices on the web. WebXR enables developers to create immersive experiences that work across a wide range of hardware platforms, including head-mounted displays, mobile AR devices, and desktop environments with appropriate peripherals.[1]

The API allows web applications to detect compatible VR/AR devices, query their capabilities, render 3D scenes to the devices at the appropriate frame rate, and respond to input from associated controllers. WebXR represents an evolution from the earlier WebVR API, expanding the scope to include augmented reality and other immersive technologies under the "XR" (Extended Reality) umbrella.[2]

History

WebVR: The Predecessor

The development of WebXR began with its predecessor, WebVR. The WebVR API was first conceived in spring 2014 by Vladimir Vukićević from Mozilla. Key contributors to the early API included Brandon Jones from Google, Boris Smus, and other members of the Mozilla team.[3]

On March 1, 2016, the Mozilla VR team and the Google Chrome team announced the WebVR 1.0 release. This early version of the API was implemented in Firefox and Chromium-based browsers, providing basic virtual reality functionality to web applications.

Transition to WebXR

As the technology evolved, developers recognized the need for a more scalable and ergonomic API that would break backward compatibility with WebVR. Initially referred to as "WebVR 2.0," the new API was officially renamed WebXR to acknowledge its expanded scope that would include both VR and AR content.[4]

The transition benefited from:

  • Experience gained from the WebVR implementation
  • A more mature landscape of immersive computing devices
  • The emergence of both mobile and headset AR technologies
  • Multiple mature native APIs to draw inspiration from

On September 24, 2018, the Immersive Web Working Group became official, formalizing the development process for WebXR standards.[5] WebXR was designed to completely replace WebVR, with all browsers that initially shipped WebVR committing to adopt WebXR once the API design was finalized.

Recent Developments

The WebXR standard continues to evolve, with the latest WebXR Device API Working Draft published in February 2022. The editors of the specification currently come from major technology companies including Google and Meta, with additional input from Mozilla, Microsoft, Samsung Electronics, Apple, as well as various startups and invited experts.[3]

Notable updates to the specification have included enhanced AR capabilities, improved performance, and broader device support. The ongoing efforts focus on standardizing and advancing the WebXR API, providing developers with the necessary tools and resources to create immersive web experiences.

Technical Overview

Core Concepts

XR Session Modes

WebXR supports different modes of operation:

  • inline - Renders XR content within an HTML element on a web page
  • immersive-vr - Provides an exclusive, fully immersive VR experience
  • immersive-ar - Blends virtual content with the real world environment[6]

Reference Spaces

WebXR uses reference spaces to define coordinate systems:

  • viewer - Coordinates relative to the user's head/device
  • local - Stationary coordinate system near the user
  • local-floor - Like local, but with Y=0 at floor level
  • bounded-floor - A floor-relative space with defined boundaries
  • unbounded - A space for world-scale AR experiences[1]

Rendering Process

At its most basic level, WebXR rendering works by:

  1. Computing the perspective for each eye's viewpoint
  2. Rendering the scene from each eye's position
  3. Delivering the combined framebuffer to the XR device for display

The API handles the complex timing and scheduling required for comfortable XR experiences, but does not directly manage 3D assets or perform rendering—that responsibility falls to WebGL or other graphics libraries.[7]

Input Handling

WebXR supports various input mechanisms:

  • Motion controllers (through the WebXR Gamepads Module)
  • Hand tracking
  • Gaze-based input methods
  • Session-specific events (select, squeeze, etc.)[8]

API Architecture

The WebXR Device API is organized into several key interfaces:

Interface Description
XRSystem Main entry point for the WebXR API, accessed via `navigator.xr`
XRSession Represents an active XR session, managing the presentation loop
XRFrame Provides information about a single frame to be rendered
XRView Represents a single view to be rendered (typically one per eye)
XRViewport Defines the rectangular area of the output canvas
XRReferenceSpace Defines spatial relationship to the user's environment
XRPose Contains position and orientation information
XRInputSource Represents input devices like controllers or hands

Modular Structure

The WebXR specification is designed to be modular, with the core WebXR Device API providing fundamental functionality and additional modules extending its capabilities:

Core Module

  • WebXR Device API - Provides basic session management, device detection, and rendering capabilities[1]

Extension Modules

  • WebXR AR Module - Adds augmented reality support through the "immersive-ar" session mode[6]
  • WebXR Gamepads Module - Provides interfaces for button, trigger, thumbstick, and touchpad input[8]
  • WebXR Hand Input Module - Enables hand tracking functionality
  • WebXR Layers Module - Supports rendering to multiple composited layers
  • WebXR Lighting Estimation Module - Allows AR applications to match virtual lighting with real-world conditions[9]

This modular approach allows the WebXR standard to evolve and expand while maintaining compatibility with existing implementations.
