The RERC on AAC is a collaborative center committed to advancing knowledge and producing innovative engineering solutions in augmentative and alternative communication (AAC). Our research and development program will emphasize strong tech transfer and employ a comprehensive dissemination plan to improve outcomes for children and adults with both developmental and acquired disabilities across the life span. We also will support a range of training and dissemination activities. Our goal is that the AAC technologies and knowledge generated by the RERC on AAC will enable individuals with complex communication needs to achieve the basic human right of communication, and to maximize their participation in education, employment, health and community activities.
