The World-Wide Augmentative and Alternative Communication (WWAAC) project is a pan-european initiative to make web and email-based technology more accessible to people with communication, language and/or cognitive impairment.
Both the world-wide-Internet and organisation-wide-Intranets currently require the user's ability to use text (traditional orthography). Without reading and/or writing text, correctly spelling email addresses etc., none of these Information Technology services widely available in our society can be used without adaptation.
The situation is particularly difficult and poorly supported for AAC-users: persons with multiple impairment, caused by congenital or acquired brain injury, including deficits in: impressive and/or expressive language, motor function (including speech), perception (interpretation and integration of sensory input), concentration and orientation, memory and general cognitive capacity.
