Modalities and governed ecosystem

Unison grows through independently maintained modality adapters and capability packages connected by common contracts. Voice, visual, Braille, sign, tactile, switch, AAC, haptic, BCI, and future teams can develop in parallel while preserving person-level authority and semantic continuity.

Common integration point

Every modality adapter contributes evidence of intent and composes governed semantic outcomes. Platform services retain identity, consent, policy, incident state, capability authority, and physical actuation decisions.

A signed capability declaration identifies supported devices, languages, features, data paths, assurance, interruption, confirmation, recovery, offline behavior, compatibility, maintainers, software inventory, and evidence. The orchestrator selects eligible adapters for the person, intent, device, and context.

Current engineering foundation

Qualification path

An adapter progresses through declared experimental capability, software evidence, representative hardware, cross-modal continuity, adversarial validation, participatory evaluation, incident readiness, and a published compatibility profile.

Braille, sign, switch, AAC, haptic, BCI, robotics, and spatial-control support depends on the hardware matrices, maintenance ownership, incident procedures, and participatory evidence appropriate to each capability. Simulation provides engineering evidence and a foundation for physical qualification.

Independent contribution

Modality teams own their language, device, interaction, performance, and maintenance expertise. The platform contract gives every team the same route into intent, identity claims, policy context, semantic outcomes, confirmation, and recovery.

New adapters declare assurance, privacy, metadata, retention, cancellation, fallback, compatibility, provenance, and support ownership. Signed packages and revocation protect the ecosystem as implementations and maintainers evolve.
