Augmentative and alternative communication (AAC) is no longer stuck with devices that make a student feel "different". With mobile devices (e.g. iPad, tablets) there are now apps for AAC. AAC apps give individuals whom have difficulties with receptive or expressive language a way to communicate effectively. This site provides 7 AAC apps ranging in price and effectiveness for different needs.
Apps for AAC is a comprehensive and powerful Web site of iPad/iPhone/iPod AAC apps, offering filtered search and comparison tools. It is maintained by Will Wade, an OT at the ACE Centre, Oxford. Wade also reviews apps in his blog posts.
