Multilingual AAC Device
Augmentative and Alternative Communication (AAC) is a term that comprises of various communication methods that allow for individuals with speech and writing impairments to express thoughts, feelings, and ideas effectively. Users of AAC can include individuals with disabilities such as Cerebral Palsy, Autism, Traumatic Brain Injury, and Parkinson's Disease. Dr. Nolan's lab has been working on an AAC device for the past 8 years in conjunction with researchers in Bolivia. After years of field study, their device's current iteration consists of capacitive touch, switches, and near-field communication modules so a non-verbal individual with low-mobility can communicate using just 4 head movements. The device outputs text using the Huffman code algorithm and has text converted into speech in English or Spanish.
