ABSTRACT:
A communication aid for a handicapped patient having only eye movement. The aid comprises a rigid transparent panel having a central opening therein and a plurality of transparent overlays each having a central aperture are individually mounted flatwise on the panel with the aperture in the overlay aligned with the opening. Each overlay contains a plurality of illustrations depicting objects or needs of the patient and the illustrations are spaced around the central aperture. An observer looking through the aligned aperture and opening can observe the eye movement of the patient and determine the illustration at which the patient is looking. The overlays are provided with identification indicia, such as a colored margin, with the color on each overlay being different than the color on other overlays, so that each overlay can be readily identified by the patient.
