ABSTRACT:
A technique is disclosed to provide eye movement measurement in which the eye position signal is corrected for head movement. A reference point and reference point monitor means are provided one of which is fixed relative to the viewer's head and the other is fixed relative to the screen. An error signal is generated when movement of the reference point is sensed by the reference point monitor means. The error signal is combined with the eye movement measurement signal to obtain a corrected reading. This technique is usable with eye movement monitoring equipment which is of the head-mounted type and that which is of the stationary type.
