ABSTRACT:
A system for viewing and recording eye movement. Enclosed spherical eye pieces form goggles which are adapted to cover each of the eyes of the user to preclude the admission of ambient light. An infrared radiation source impinges upon the user's eye, the radiating energy being in the non-visible portion of the energy spectrum. The interior surface of each eye piece is coated with a surface adapted to reflect and disperse the radiating infrared energy. An infrared sensitive video camera is directly coupled to the goggle eye pieces, the camera being sensitive to infrared radiation. The output of the video camera is connected to monitoring apparatus for monitoring and recording the real-time observation of the user's eye movements.
