Clarification Request: XR_BD_controller_interaction rev 2

[amini-allight]

For the new Pico G3 bindings in the XR_BD_controller_interaction extension the thumbstick path is listed as simply:

.../input/thumbstick

Whereas all other thumbsticks in OpenXR are:

.../input/thumbstick/x
.../input/thumbstick/y

Is this a mistake or meant to indicate some different functionality of the thumbstick action? The summary of input types here seems to suggest thumbsticks should always have x and y components.

I believe your interpretation is correct. (I thought I had removed the bare /thumbstick and left only the /thumbstick/x and /thumbstick/y during the editing process...) If you look at the XML version, it's shown as a vec2f: https://github.com/KhronosGroup/OpenXR-Docs/blob/main/specification/registry/xr.xml#L6282

I will check with the vendor to verify.

Thanks @amini-allight for reporting the issue and @rpavlik for helping respond. I confirmed with my colleagues, the spec was supposed to include those two components for G3 controller:

.../input/thumbstick/x
.../input/thumbstick/y

and our PICO OpenXR runtime already supported them so you should be able to use the two paths with no problem. We will send a change to fix the spec language.
