<yonet> Face to face meeting on April 21-22nd, San Francisco: https://www.w3.org/events/meetings/49c83780-eb0d-4d0a-a619-4d8f0637f7dd

Ada: Does it have a "squeeze"?

Lachlan: Depends on target mapping.

Nick: Q to Rik: When does this (OpenXR) happen?

Rik: Need to change settings to enable OpenXR.

Brandon: Does it handle hand-off between controllers & hands?

Rik: Yes

Brandon: Any known issues (feature regressions) in the OpenXR path?

Rik: Some lingering (fatal) bugs. Current release is pretty stable

<Zakim> alexturn, you wanted to ask if enabling hand tracking would cause you to not enumerate an XRInputSource for hands

Alex: If hand tracking is enabled, does the user get hands + joints or just one.

Rik: Joints are extra data to go with hands

Rik: Confirmed Aysegul will do testing.

Yonet: Agrees

webxr-hand-input#112 add flag to relay validity of target ray space requested by cabanier

https://github.com/immersive-web/webxr-hand-input/issues/112

Rik: Previously discussed. Suggest postponement. This happens when the hands are "palms-up", which indicates a system gesture.

<Zakim> ada, you wanted to ask about why since no system action happens

Ada: Discussion with Rik to determine about an unusual feature. Determined that it was a bug. Details to be provided.

<Zakim> alexturn, you wanted to talk about still giving out target rays but capturing select

Alex: Expose the target ray, but with a flag indicating that it was a system gesture.

Rik: Oculus does not pass out system gestures.

Rik: Confirmed information for #112
