Meta Extension describes spatial keyboard with template, animation and text context. See benefits, limits and risks of portability.
Direct answer
The OpenXR `XR_META_virtual_keyboard` extension defines resources for creating and positioning a virtual keyboard, loading model and texture, applying animations, providing text context, and receiving interaction by hands or controllers. It is a Meta extension and not a Khronos-ratified extension, so its availability depends on the runtime. For XR products, the value is in standardizing integration across the supported ecosystem while maintaining fallback and testing for privacy, accessibility, and portability.
Model and behavior are coordinated
The API brings together geometry, texture, animation, and state to avoid fragmented integrations.
Text context calls for minimization
Field information can be sensitive; share only what is necessary and do not log content by default.
Hands and controls expand input
Ray and direct touch meet different scenarios, but they need targets, feedback and error correction.
Vendor extension limits reach
Support must be consulted at runtime and accompanied by alternatives for other runtimes.
Nexus Reading
Adopt by capability, not assumption, and validate language, ergonomics, privacy, and fallback on target hardware.
FAQ
Is the extension part of the OpenXR core?
No. It is an extension of the Meta and is not ratified by Khronos.
Does it support hands and controllers?
The specification provides for direct and ray input sources.
How to maintain portability?
Consult runtime support and offer an alternative input method.
