The pattern draft allows you to create, track, persist, and restore spatial anchors. Understand stability, lifecycle and privacy.
Direct answer
The WebXR Anchors Module allows you to ask the XR system to track a fixed pose relative to the real world and update the content as the spatial understanding changes. The April 27, 2026 Editor's Draft also describes persistent identifiers for restoring anchors. The feature improves stability and return to a position, but remains work in progress; persistence, support, consent and opt-out need to be addressed explicitly.
Anchor accompanies map review
The system can adjust the pose when it better understands the environment. The application uses anchor space instead of assuming immutable coordinates.
Persistence creates expectation of return
A restorable identifier allows content to be retrieved in another session, but does not guarantee eternal availability. The product needs to explain validity, synchronization and recovery.
Lifecycle needs deletion
Abandoned anchors consume resources and can expose information about the location. Offer removal, retention period and separation by user, environment and purpose.
Compatibility remains experimental
The document is Editor's Draft and may change. Detect the feature, maintain a non-persistence mode and test the behavior when tracking becomes unavailable.
Nexus Reading
Anchors are the bridge between transient effect and continuous spatial interface. Enterprise value requires place identity, governance, and fault tolerance, not just a technically valid pose.
FAQ
Does an anchor hold the 3D model?
No. It represents a spatial reference; content and data remain the responsibility of the application.
Does persistent mean permanent?
No. Availability and duration depend on product implementation, permissions, and policy.
How does positioning begin?
It is common to use hit testing to choose a surface and then create an anchor in the confirmed pose.
