Abstract (en)
[origin: WO8303341A1] A computerized electro-oculographic system has a rotatable subject chair (2) surrounded by a cylindrical screen (18) on which the desired optical stimuli from projectors (12, 16) are displayed. Eye movement signals are picked up by electrodes (6a-1) amplified (24, 26), calibrated (46), filtered (26) and digitized (28) for interface (30) with a computer (32). The tests to be run are selected by a keyboard (44) to operate the computer according to its programs (36). The computer signals are then displayed (38) and/or recorded (40, 42).
