The latest update to the Oculus Integration for Unity adds the Quest’s controller-free hand-tracking to the editor.

Unity XR Hands Package “The XR Hands package defines an API that allows you to access hand tracking data from devices that support hand tracking.

When implementing and testing Hand Tracking support for Myst in Unreal, we noted some quirks with the tracking stability for certain fingers when they’re occluded by the rest of your hand.

Hand tracking allows you to drop the Quest's two controllers and use your own hands in virtual space, which is pretty amazing to play with in an immersive sense.
