This pull request adds the support for hand tracking microgestures, a Meta OpenXR extension - compatible with Quest 2/Pro/3/3S - that adds five boolean inputs per hand (thumb tap + D-pad–like swipes). `WebXROculusHandController` has been created starting from `WebXRGenericHandController` as base and mapping the input profile with the`oculus-hand` profile: https://github.com/immersive-web/webxr-input-profiles/pull/274/files. ___ ### Behaviour As today, all the input controller profiles are retrieved from the WebXR controller [repository](https://immersive-web.github.io/webxr-input-profiles/packages/viewer/dist), unfortunately, the `oculus-hand` controller is missing. I made the PR immersive-web/webxr-input-profiles#278 to add it, but i don't know if/when it will be approved. **As-is** 1. Starting a WebXR session with a compatible Quest device, `xrController.inputSource.profiles` is correctly populated with `oculus-hand` profile: ```ts ['oculus-hand', 'generic-hand', 'generic-hand-select', 'generic-trigger'] ``` 3. All input controller profiles are retrieved from: https://immersive-web.github.io/webxr-input-profiles/packages/viewer/dist/profiles/profilesList.json (but `oclus-hand` is missing). 4. Get `generic-hand` because it is the first available profile: https://immersive-web.github.io/webxr-input-profiles/packages/viewer/dist/profiles/generic-hand/profile.json 5. Map `generic-hand`. **To-be (after pull request is merged)** 1. The user create an XR experience disabling the online controller repository (see "Considerations" below): ```ts scene.createDefaultXRExperienceAsync({ inputOptions: { disableOnlineControllerRepository: true } }) ``` 2. Starting a WebXR session with a compatible Quest device, `xrController.inputSource.profiles` is correctly populated with `oculus-hand` profile: ```ts ['oculus-hand', 'generic-hand', 'generic-hand-select', 'generic-trigger'] ``` 3. The `oculus-hand` profile is retrieved from Babylon.js itself (local). ___ ### Note Forcing the input profile: ```ts scene.createDefaultXRExperienceAsync({ inputOptions: { forceInputProfile: 'oculus-hand' } }) ``` is not a valid option because in any case the `generic-hand` profile will be retrieved. ___ ### Test Tested with Oculus Quest 3. Playground (valid after PR build): https://playground.babylonjs.com/#F41V6N#2275. ___ ### Considerations When the `oculus-hand` profile will be added to online repository, it shouldn't introduce regressions because the `oculus-hand` it will be retrieved and consumed automatically. The `oculus-hand` profile is 1:1 mapping with `generic-hand` profile with the adding of specific swipe components (`menu` - only left hand, `swipe-left`, `swipe-right`, `swipe-forward`, `swipe-backward`, `tap-thumb`). ___ ### Discussion Forum link: https://forum.babylonjs.com/t/hand-tracking-microgestures/60860.

This PR adds the
oculus-handprofile to the WebXR Input Profile Viewer’s profile selector and makes the profile available at: https://immersive-web.github.io/webxr-input-profiles/packages/viewer/dist/profiles/oculus-hand/profile.json.Assets
left.glbandright.glbwere generated in Blender using thegeneric-handmeshes as a base:swipe-left,swipe-right, etc.) as empty axes objects, following the guidance in the tutorialViewer behavior
As with the
generic-handprofile, the sliders in the Viewer do not affect the model. My assumption is that hands are a special case (unlike typical controllers). If this is not the intended behavior, this PR can serve as a starting point for further adjustments.
