Augmentative and Alternative Communication
(AAC) attempts to compensate for temporary or permanent impairments, activity limitations, and participation restrictions of individuals with disorders of speech-language production and/or comprehension, including spoken and written modes of communication. ITHACA framework is an Open Source, component-based environment that facilitates software developers and application integrators to build and assemble computer-based interpersonal AAC aids.
AAC software companies, developers and independent Open Source code contributors may use ITHACA guidelines and tools to construct AAC software modules. Available resources (documents, open source code, and compiled program and components) can be downloaded from this site.
Specialized AAC resellers, therapists, and educational-rehabilitation organizations are welcome to download the ITHACA main executable program and open source peripheral components. Until now, all software is free, but commercial components may be added in the future (licensing and distribution will be managed by the commercial components owners in this case). User manuals and application assembly guidelines are also available online.
