No API to suppress Guardian boundary during walking/gait tasks (Unbounded mode not supported)

[blondarb]

Summary

During walking assessment tasks in our clinical app, the Guardian boundary wall fades in and obscures our navigation markers when the patient walks more than a few meters. We need to suppress or expand the boundary programmatically during supervised walking tasks.

What We Observe

• XRInputSubsystem.GetSupportedTrackingOriginModes() returns 0x3 (Floor + Device only) — Unbounded is not supported
• TrySetTrackingOriginMode(TrackingOriginModeFlags.Unbounded) is not available
• TrySetBoundaryPoints(empty list) via reflection — method exists but returns false
• TryRecenter() works but only delays boundary appearance; does not prevent it
• There is no visible API to toggle boundary wall visibility

What We Have Tried

1. Setting tracking origin to Unbounded — not in supported modes
2. Clearing boundary points via TrySetBoundaryPoints(new List<Vector3>()) — returns false
3. Switching to Device tracking mode — boundary still appears
4. Recentering the play space — delays but does not prevent boundary
5. Rendering our gait markers with ZTest Always to show through boundary fade — partially works but poor UX

Use Case

SDNE is a clinical neurologic exam that includes standard gait assessment tasks:

• 10-Meter Walk Test — patient walks 3-10 meters at normal pace (speed, cadence, stride length measurement)
• Timed Up-and-Go — patient stands, walks 3 meters, turns, walks back, sits (fall risk assessment)

These tasks are performed under medical assistant supervision with passthrough enabled. The boundary wall interfering with walking guidance is a significant clinical UX problem — patients may stop walking or become disoriented when the boundary fades in.

Questions

1. Is there an API or intent to temporarily suppress the Guardian boundary for supervised activities?
2. Is XR_ANDROID_unbounded_reference_space planned for Galaxy XR in a future firmware/SDK update?
3. Is there a way to programmatically expand the boundary to a larger area from within the app?

Environment

• Device: Samsung Galaxy XR (SM_I610)
• OS: Android XR
• Unity: 6000.3.6f1
• OpenXR runtime
• Tracking origin: Floor mode (0x1)
• Passthrough enabled during gait tasks

Hi , Did you find any solution to this ? We are facing similar issue

Thanks

Please check the UnboundedRefSpace sample. You need to enable the Android XR: Unbounded Reference Space feature in Edit > Project Settings > XR Plug-in Management >
OpenXR.

The XR_ANDROID_unbounded_reference_space extension purpose is to provide a space that is independent of the center of the boundary and typically used for anchoring. It is simply a world-scale tracking solution to prevent mathematical drift. Anytime you press recenter button in your quick settings, using unbounded reference space will prevent your virtual objects from moving.

Enabling this extension does not disable the guardian safety feature. Currently we don't have any OpenXR extension for AndroidXR that disables the guardian safety feature, but you should be able to disable it from developer options on the device.
