XRAccessibility Project Overview

The XRAccessibility Project is an initiative driven by the XR Association and XR Access to provide a central place for developers to find solutions for creating accessible code across various XR platforms. We were inspired by developers, key players in ensuring that this technology is accessible, who reported challenges in finding accessible code snippets. It features:

  • Strategies, code, and tutorials to solve accessibility concerns across a wide range of platforms

  • An index that points to resources all over the internet, organized by platform

  • Validation of resource usability and functionality

  • A contribution form for adding additional resources to this project

Featured Platforms

Platform Supported Devices
ARCore Android
ARKit iOS
LuminOS Magic Leap One
Unity Many
Unreal Many
WebXR Web browsers
Windows Mixed Reality Microsoft HoloLens
Microsoft HoloLens 2
Windows Mixed Reality headsets

How to Contribute

The XRAccessibility Project is open source. If you know of resources that other developers could benefit from, please share them!

To contribute to the XRAccessibility Project, fill out our resources submission form.

Submissions should preferably include a video demonstration and/or a text walk-through, so that potential users don't have to deploy a solution to understand what it does. Suggestions will be reviewed on the basis of clarity, functionality, and usefulness.

  • Clarity: is it clear what the resource does? Does it come with a demo or video?

  • Functionality: does the resource work? Is it regularly updated and maintained?

  • Usefulness: does the resource provide useful code snippets or otherwise help developers?

For other comments and suggestions, feel free to file an issue using Github.

General Resources to Help You Get Started

If you’re new to XR and Accessibility, then check out these resources for concepts and ideas:

XRA’s Developers Guide, Chapter Three: Chapter Three is an update to XRA’s Developers Guide, a starter guide for developers designing reality-expanding experiences. This standalone update, “Accessibility & Inclusive Design in Immersive Experiences,” offers a set of industry-backed best practices for developing accessible platforms that enhance experiences for all users, not just those with disabilities.

XR Association Developers Guide

PEAT - Inclusive XR in the Workforce: This resource will help anyone who wants to use immersive technologies in the workplace. Each section will help organizations to ensure the immersive technologies they adopt are accessible for all.

PEAT - Inclusive XR in the Workforce

XR Access Resources: The XR Access Initiative, whose mission is to modernize, innovate, and expand XR technologies, products, content and assistive technologies by promoting inclusive design in a diverse community, has put together a list of resources representing a sample of other accessible XR projects, and resources to help ensure that XR is accessible to all.
