Ongoing Projects at the AAC Lab
Our research aims to improve the efficacy of Augmentative and Alternative Communication intervention for persons with severe speech and language impairment as a result of developmental and acquired conditions. Our research primarily focuses on adults with neurogenic communication disorders such as aphasia and children diagnosed with autism and other developmental disabilities. To accomplish these lines of research, the AAC lab is equipped with several dedicated speech generating devices (e.g., Dynavox, TobiiDynavox, Lingraphica, and AMDi communication devices), stand-alone apps on multipurpose handheld devices, eye tracking software programs, and a state of the art electroencephalographic-based brain-computer interface system.
Ongoing research projects include investigations into the perceived communicative competence of persons with aphasia communicating with AAC devices with various display configurations, symbol identification, the perception of synthetic speech, variables that influence outcomes of interventions with eye-tracking AAC devices, and inquiry into the efficacy of EEG-based brain-computer interface system with persons with developmental and acquired disabilities.
