Signal Processing to Drive Human-Computer Interaction: EEG and eye-controlled interfaces — Recommend this title to your library

Thank you

Your recommendation has been sent to your librarian.

A radically new perspective on natural computer interaction is considered that has gained momentum aiming to deliver the technology that will allow people to operate computer applications using their eyes and mind. This interaction uses eye movements captured through eye-tracking devices following the user's gaze and brain electrical signals captured through electroencephalography (EEG) devices reflecting the brain's state. The fundamental assumption underlying this radically new perspective is that the signals (i.e. eye movements and brain electrical signals) obtained from people with motor impairment that are in good mental health can be reliably used to drive the interface control of a computer application.
