Brain-Computer Interface Integrated Augmentative and Alternative Communication
Project Overview
The primary objective of Ms. Shea’s research is to investigate an optimized integration of event related potentials (ERPs) as a means to augment assistive communication devices. Words, chosen through contextual constraints and rapidly presented to individuals offer superior communication efficiency over independent sequential letter selection. During the rapid presentation of words, recognition of the desired word will elicit an evoked front-central potential known as the P300. Advanced bio-signal processing, such as wavelet denoising, and independent component analysis to remove ocular artifacts, and classification technologies will be investigated to achieve the necessary single trial ERP identification. Additionally, the need for gaze shift will be eliminated by presenting the potential words at the cursor location.
