Many individuals with rare communication disorders find generic AAC apps inadequate. Their specific conditions require customized vocabulary sets and interaction flows.
Create modular AAC apps that can be tailored to different neurological conditions. Offer condition-specific starter packs with relevant vocabulary and interaction patterns.
Schools and care facilities would pay for specialized versions that reduce setup time. Families may purchase personal licenses for home use.
Start with one well-researched condition (like aphasia after stroke) and build the vocabulary/interface for it. Validate with speech therapists.
The biggest risk is underestimating medical/ethical considerations in assistive technology.
