Augmentative and Alternative Communication

Persons with complex communication needs (CCNs), use augmentative and alternative communication (AAC) devices to express thoughts, needs, wants, and ideas when they cannot rely on their speech to communicate. Some examples of these devices include specialized keyboards along with adapted controllers and text-to-speech interfaces. We are exploring different ways people use AAC devices in dyadic interactions to inform new designs that can reduce user burden of persons with CCNs and motor impairments and enable the design of more personal AAC interfaces.
