Problem

Assistive communication systems are fragmented.

Most tools solve isolated problems such as speech, hearing, or vision, forcing users to:

Switch between multiple interfaces

Learn different interaction models

Depend on external assistance

The real failure is not missing features.

It is the absence of a unified system.

Solution

UACS introduces a single communication pipeline:

Speech ⇄ Text ⇄ Morse ⇄ Haptic

Morse code acts as a consistent encoding layer, enabling deterministic translation across all modalities.

System Architecture

The system is built using a dual-layer architecture:

Processing Layer (Raspberry Pi)

Speech capture

Speech-to-text conversion
