Gaze Tracking and Assistive Technology

Direct Brain Interfaces (DBIs) offer great possibilities for people with severe disabilities to communicate and control their environments. However, many DBI systems implement discrete selection, such as choosing a letter from an alphabet, which offers limited control over certain tasks. Continuous control is important for applications such as driving a wheelchair or drawing for creative expression. This paper describes two projects currently underway at the Georgia Tech BrainLab exploring continuous control interface paradigms for an EEG-based approach centered on responses from visual cortex, and functional near Infrared (fNIR) imaging of the language center of the brain.
