[Quest] Interactable moves further away or closer depending on the turning direction when UseDistanceBasedVelocityScaling is enabled

Package: XR Interaction Toolkit

-

Reproduction steps:
1. Open the attached project "ReproProj"
2. Open the “/Assets/Samples/XR Interaction Toolkit/3.0.3/Starter Assets/DemoScene.unity” Scene
3. Enter the Play Mode
4. Teleport to the Grab Interactable Objects
5. Grab any interactable
6. Turn left with head and controller
7. Observe the interactable moves closer to the controller
8. Turn right

Expected result: The interactable does not change distance from the controller
Actual result: The interactable moves further away from the controller

Reproducible with: 3.0.3 (2021.3.44f1), 3.0.5 (2021.3.44f1, 2022.3.50f1, 6000.0.22f1)

Reproducible on:
Play Mode
Windows Standalone Player
VLNQA00379, Oculus (Quest 2), Android 10, CPU: Snapdragon XR2, GPU: Adreno (TM) 650

Testing environment: Windows 10 Enterprise 21H2
Not reproducible on: No other environment tested

Note:
- Reproducible when holding interactable lower than the controller

  1. Resolution Note (fix version 3.0.7):

    Fix description:
    - Upgraded attach velocity tracker estimation method to use weighted linear regression, which helps make the velocity estimate both more accurate and resilient to jitter and noise. Because it's weighted to newer time steps too, it exhibits lower latency as well.
    - Removed plane projection logic preventing z-motion from working if not moving along the ground plane.
    - Added filtering cone of 30 degrees to prevent unintended lateral motion from triggering z-motion of the objects.
