OpenXR is composed of the core feature-set, multi-vendor extensions, and vendor-specific extensions. One of those vendors-specific extensions is VARJO_quad_views, available on Varjo HMDs as the name of the extension indicates. By default, in OpenXR, an application will generate two images, one for each eye. This is known as stereo views. But one unique capability of Varjo HMDs (except the Aero), is to have two displays per eye, allowing human eye resolution in the center area of the screen. The purpose of VARJO_quad_views is to enable the application to generate one view covering the entire field of view at the resolution of the context screen, and one inner view to match with the resolution and field of view of the focus screen (padded for taking into account the head movement and latency).

The VARJO_foveated_rendering extension is augmenting the VARJO_quad_views extension by adding eye tracking. The idea is that every rendered frame the application will be provided a different position of the inner view based on where the eyes are looking at. But also, since we know where the eyes are looking, the size of the inner view is much reduced from the default quad_views. And then the resolution of the outer view can also be reduced, as there is no need to even calculate as many pixels as the context screen can display, because even though it is not as high resolution as the focus screen, it is still higher resolution than the eye can detect at its periphery.

HTC VIVE announced developers can now join the OpenXR public beta program for the VIVE Focus 3. Developers have access to start new projects or port existing applications to multiple XR devices. OpenXR compatibility benefits consumers in addition to developers, giving them more flexibility to enjoy their VR content on multiple devices, including high-performance headsets like VIVE Focus 3.

The Award-winning technology company announces it received the prestigious financial grant form Epic, the company behind the popular Unreal Engine and Fortnite. The Epic MegaGrant is awarded for the further development of its OpenXR runtime, adopting the industry-standard. With recently being honoured an Innovation Award at CES last January, this is the 2nd award the Dutch technology company wins in Q1 of 2022 based on its Simulated Reality technology.

Godot recently released Godot 4.0 alpha 4 release candidate. In the release, Godot promoted OpenXR from a plug-in into the core for better integration with Vulkan and other engine components.

The Khronos Group has an open Request for Quote (RFQ) for OpenXR CTS Improvements. The OpenXR working group has developed a conformance test suite for validating vendor runtimes against the OpenXR specification to help ensure uniformity across AR and VR platforms. This project will extend the current conformance test suite with additional tests of the core specification as well as implementing tests for a number of extensions. The OpenXR Working Group may also seek some sample development to provide application developers simple example code to bootstrap their own development efforts. The deadline for RFQ submission has been extended to Friday, March 25th, 2022.

The Haptics Industry Forum (HIF) and The Khronos® Group have entered into a cooperative liaison agreement to foster synergy between the two organizations to encourage the integration of advanced haptics functionality into the Khronos OpenXR™ open standard for portable augmented and virtual reality, to enable broad availability of haptics in the metaverse and beyond. This agreement enables HIF and Khronos to collaborate with a shared goal to enable broad, cross-platform access to next-generation haptic feedback in XR applications, enabling rich multisensory experiences to reach beyond 3D visuals for the eyes and spatial audio for the ears – and include expressive haptics for touch.
