Augmentative and Alternative Communication Lab

About the Facility
The goals of the lab are to decrease barriers to participation in society for individuals using augmentative and alternative communication (AAC). There are over 3.5 million individuals in the United States whose natural speech is inadequate to meet their daily communication needs (Beukelman & Mirenda, 2005). The population is extremely heterogeneous covering children and adults with developmental disabilities such as cerebral palsy or autism, acquired disabilities such as those from a stroke or traumatic brain injury, degenerative disorders such as ALS or Parkinson's disease, and conditions resulting in individuals being temporarily unable to speak such as post-surgery. These individuals can benefit from augmentative and alternative communication (AAC) strategies such as gestures, signs, alphabet or picture based-boards, or computer-based systems with synthesized speech output. 

Research focuses on:

  • Improving the design and accessibility of AAC systems
  • Creative Expressions by and for individuals requiring AAC
