Accessibility#

WCAG 2.2 AA is the minimum web/surface target. Spatial presentation adds requirements rather than replacing interface semantics.

Every interactive Component exposes name, description, semantic kind/state, focus anchor/order, Actions/consequences, authority constraints, ≥44 px target, non-color cue, reduced-motion form, and visible focus. Scene reading order: purpose → Area → current Avatar → nearby authorized relationships → focal Components → Portals → distant Areas → ambient description.

Provide semantic travel, route narration, persistent orientation landmark, captions/transcripts, spatial-audio alternatives, haptic alternatives, contrast protection, 200% zoom, screen-reader map, reduced motion, reduced sensory mode, remappable controls, speech input, and time extensions. Orientation questions support text, speech, prompts, or Artifact placement. Timers stop when accessibility needs or comprehension require it unless an external real-world deadline exists and is honestly disclosed.

Accessibility testing includes keyboard-only, VoiceOver/TalkBack, switch scanning, 200% zoom/reflow, color-vision simulation, reduced motion, captions, cognitive walkthrough, and users with relevant disabilities before production acceptance.
