I’m trying to implement XR to include the “lowest common denominator” i.e. Google Cardboard. Before I reinvent the wheel, and implement gaze selection with pick and projection, does XR implement an equivalent of enableInteractions? TIA

The WebXR polyfill is your friend. I solved an issue that prevented it from working correctly (in general - canvas resizing) and it should now be supported. It does have cardboard support and it is maintained by the great people at the immersive web group - GitHub - immersive-web/webxr-polyfill: Us…

I think there’s been a bit of a misunderstanding. I would like to know whether WebXRExperienceHelper has an equivalent to VREXperienceHelper's enableInteractions. Or am I misunderstanding what enableInteractions did? TIA

Oh! Sorry!! The pointer selection feature should take care of every type of XR interaction - screen, gaze and tracker-pointer. It is enabling per default. A few changes are planned - [XR] changes to PointerSelection behavior · Issue #7974 · BabylonJS/Babylon.js · GitHub , but in general it is stable…

So how does gaze actually work (I’m trying to work it out but getting nowhere)?

Gaze mode is enabled to gaze enabled devices (devices that state their input type to be gaze). Some devices like the cardboard might be recognized as screen instead of gaze, which might complicate things a bit. If the device is a tracked-pointer and you want gaze support you can force gaze mode whe…

Hmm, this simple playground ( https://playground.babylonjs.com/#M1HAX5 ) doesn’t seem to exhibit gaze behaviour (unless I’ve missed something out or misunderstood).

What device are you testing on?

Every device uses a different pointer-selection feature. tracked pointer have their controllers, screen has touch-enabled, and gaze devices have a gaze ring. If you want gaze mode enabled instead of the controllers, you can force it. If you want gaze on screen-mode devices (usually smartphones) I c…

Early days so on PC only for now until I have something a bit more functional… soon. Then testing on Samsung Edge, and Google.

For now, at least, I think I’ll just implement something myself.
