Explainer


https://github.com/immersive-web/webxr-hand-input/blob/master/explainer.md


Specification

https://immersive-web.github.io/webxr-hand-input/


API spec

Yes


Summary

https://immersive-web.github.io/webxr-hand-input/ Exposes hands as an XrInputSource for use during a WebXr session. When hands are detected, this allows the API to expose them as the "hand-tracking" type, which can also allow exposing a fully-articulated hand model.




Blink component

Blink>WebXR


Motivation

XR systems support tracking of users' hands to allow direct interaction and manipulation of virtual objects in XR applications. This feature provides sites an interface through WebXR to make use of these system hand trackers in a standardized way.




Initial public proposal

I'm excited to hear that you are planning on implementing WebXR Hands!
For reference, this spec is already implemented by Servo for Hololens and the Oculus browser for Quest/Quest2. Most popular frameworks already support it.

Lachlan, if this feature is approved for prototyping, we can share our implementation with you.

Sounds good to me! The plan is to implement it atop the equivalent OpenXR spec which Mozilla was also consuming so that would be helpful.
