The ten dimensions

1. Modality — which modes must work (text, audio, video, captions, signing, etc.).
2. Latency — whether access is timely enough to be functionally equivalent.
3. Persistence — what must be retained (records, logs, transcripts, settings).
4. Identity — who is speaking / acting; attribution and authentication.
5. Delegation — who can act on behalf of a user (interpreters, assistants, agents).
6. Context — meeting state, conversation state, task intent, and situational cues.
7. Device Class — phone, desktop, kiosk, wearable; capabilities and constraints.
8. Environment — noise, lighting, bandwidth, safety context, shared spaces.
9. Control & Consent — user control of features, sharing, and assistive settings.
10. Auditability — ability to prove what happened and how decisions were made.

Why this matters

A single “feature” rarely satisfies Part 14 in isolation. Real-world access requires thinking across these dimensions together — and producing evidence that supports defensible records.

14ten provides the structure to do that consistently.
