Accessibility is part of correctness¶
Native participation through every modality
A complete experience is one the person can use
Unison composes interaction through the forms that work for each person and situation, including conversation, visual presentation, Braille, sign, touch, switches, AAC, haptics, and future modalities.
Native experience is the product¶
A conversational experience uses dialogue, pacing, interruption, prosody, and auditory structure. A visual experience uses composition, typography, imagery, and spatial relationships. A Braille experience uses tactile structure, routing, concise labels, and direct navigation. Sign, switch, AAC, touch, haptic, and future pathways use their own language and interaction strengths.
The semantic outcome provides the common meaning. Each modality composes that meaning directly for the person. This makes accessibility part of the Unison experience architecture and gives independent modality teams a shared integration point.
Completion includes the whole journey¶
A capability is complete in a modality when the person can:
- express and refine intent;
- understand identity, privacy, capture, and disclosure state;
- perceive facts, provenance, uncertainty, urgency, and errors;
- navigate choices and understand their consequences;
- confirm, cancel, interrupt, retry, and recover;
- move to another authorized modality while retaining state; and
- review the outcome through an appropriate durable form.
Equivalent meaning and control are required across supported modalities. Information density, sequence, pacing, and representation can follow each modality's strengths.
Personalization and context¶
The experience composer considers personal preferences, language, notation, device capabilities, environment, fatigue, urgency, privacy, and the assurance required for an action. Preferences remain under person-level authority and can change across contexts.
Shared experiences preserve a common semantic state while each participant receives a native expression. Private context and interaction preferences remain within each person's governed space.
Evidence defines support¶
Automated WCAG 2.2 AA checks provide a baseline for web content and visual surfaces. Semantic journey tests validate meaning, confirmation, cancellation, and recovery. Representative-device tests measure compatibility, latency, and degraded behavior. Participatory evaluation determines whether the experience works for people who use the modality.
A supported claim identifies the modality, devices, languages or notation, capabilities, environment, and evidence collected.
