Tracking eye fixations with electroocular and electroencephalographic recordings.

摘要: We describe a method, based on recordings of the electroencephalogram (EEG) and eye movement potentials (electrooculogram), to track where screen (x,y coordinates) an individual is fixating. The method makes use empirically derived beam-forming filter (derived from sequence calibrated movements) isolate motion other electrophysiological ambient electrical signals. Electrophysiological researchers may find this simple inexpensive means tracking movements useful complement scalp in studies cognitive phenomena. resolution comparable that many commercial systems; can be implemented with as few four electrodes around eyes EEG already use. This also some specialized applications such studying during sleep human-machine interfaces make gaze information.
