AR (Augmented Reality)
Use when the user is building AR on WebXR (immersive-ar) or native (ARKit/ARCore/OpenXR).
Fast Defaults
- Prefer stable world-locked content; avoid screen-locked UI unless necessary
- Use clear permission prompts and visible camera-on indicators
- Start with: hit-test + placement + anchors + simple interaction
AR Capability Checklist
- Plane / mesh detection
- Hit-test (placing content onto surfaces)
- Anchors (persistent placement)
- Occlusion (depth) and lighting estimation if available
- Safety boundaries (keep critical UI in view, avoid distraction)
Debug Checklist
- Confirm session type (WebXR
immersive-ar) or native runtime - Verify tracking origin and world scale (1 unit = 1 meter)
- Confirm anchor lifetimes and relocalization handling
