Semantics helps choose surfaces for AR content, but the state may be unavailable or change. See how to design with confidence and fallback.
Direct answer
ARKit can classify plane anchors as wall, floor, ceiling, table, seat, door, or window on supported devices. The classificationStatus property indicates the stage of the analysis, and the classification may not be available or may be updated as the session observes more of the environment. The feature is useful for guiding placement and interface, but should not automatically trigger a critical action without visual confirmation and a manual alternative.
Semantics reduces inappropriate choices
An application can suggest a floor for navigation or a table for an object, rather than treating every horizontal surface as equivalent.
State needs to be shown as trust
While classification is not ready or uncertain, the interface should avoid definitive language and allow the user to confirm the surface.
Anchors evolve during the session
Extent, pose, and label may change with new observations. Content must keep up with updates without skips or loss of context.
Manual fallback protects the flow
Atypical environments, lighting and materials may impede classification. Assisted selection or repositioning keeps the task possible.
Nexus Reading
Use classification as a semantic recommendation, combine it with geometry and context, and record human corrections to improve product design.
FAQ
What surfaces can be classified?
Wall, floor, ceiling, table, seat, door and window are among the official categories.
Is classification always immediate?
No. The status may indicate analysis in progress or lack of classification.
Can I block the flow if there is no label?
Avoid. Offer manual confirmation or positioning when semantics are not available.
