'''OpenXR''' is an [[open-source]], [[royalty-free]] standard for access to [[virtual reality]] and [[augmented reality]] platforms and devices.<ref name="release-0.90"/> It is developed by a [[working group]] managed by the [[Khronos Group]] consortium. OpenXR was announced by the Khronos Group on February 27, 2017, during [[Game Developers Conference|GDC 2017]].<ref name="khronos-reveal">{{cite web| url=https://www.khronos.org/news/press/khronos-reveals-api-updates-new-workgroups-at-gdc | title=Khronos Reveals API Updates & New Working Groups at GDC

Reviewers of the 0.90 provisional release considered that the aim of OpenXR was to "Solve AR/VR Fragmentation".<ref name="infoQ">{{cite web

| quote=''With Monday’s release of the OpenXR provisional specification, Khronos’ open source working group wants to create a world where developers can code their VR/AR experience for a single API, with the confidence that the resulting application will work on any OpenXR-compliant headset.''
 +
| access-date=2019-06-20}}</ref>
 +
 +
== Architecture ==
 +
The standard provides an [[Application programming interface|API]] aimed for application developers targeting [[virtual reality]] or [[augmented reality]] hardware.  This enables developers to build applications that will work across a wide variety of devices.<ref name="kronospres">{{cite web
 +
| url=https://www.khronos.org/blog/the-openxr-working-group-is-here
 +
| title=The OpenXR Working Group is Here!
 +
| date=2017-02-27
 +
| publisher=[[Khronos Group]]
 +
| quote=''The OpenXR standard comes in two parts. First, the Application Interface, which application developers and middleware providers write to, and which serves to define and combine common, cross-platform functionality(...)Next, the Device Layer allows VR/AR runtimes to interface with various devices''
 +
| access-date=2017-03-08}}</ref>
 +
 +
The fundamental elements of this API are:
 +
* <code>XrSpace</code>: a representation of the [[Three-dimensional space|3D space]]
 +
* <code>XrInstance</code>: a representation of the OpenXR runtime
 +
* System and <code>XrSystemId</code>: a representation of the devices, including the [[Virtual reality]] or [[Augmented reality]] devices and controllers
 +
* <code>XrActions</code>: used to handle user inputs
 +
* <code>XrSession</code>: represents the interaction session between the application and the user
 +
The full specification can be found via the [https://registry.khronos.org/OpenXR/#apispecs OpenXR Registry] on [[GitHub]].

== Roadmap ==
 +
After the release of OpenXR 1.0, progress will likely be driven through the development of extensions to the core API.<ref>{{Cite web |date=2019-07-29 |title=Khronos Releases OpenXR 1.0 Specification Establishing a Foundation for the AR and VR Ecosystem |url=https://www.khronos.org/news/press/khronos-releases-openxr-1.0-specification-establishing-a-foundation-for-the-ar-and-vr-ecosystem |access-date=2022-11-19 |website=The Khronos Group |language=en}}</ref> This can be seen in the subsequent release of extensions for support of hand tracking and eye gaze tracking.<ref>{{cite web

 +
As implementers and developers get more experience with the extensions, they could get integrated into the core OpenXR API in future releases.
