Abstract: Disclosed herein is a device for measuring horizontal and vertical eye movement utilizing infrared technology. The device rests on the user's nose and, in alternate versions, can be secured to the user's head via a head strap or temple arms which will provide greater alignment and applications. It is comprised of a nose bridge piece and mounting means which house the calculation and measurement technology. The nose bridge is similar to that of ordinary eye glasses with the mounting means, or head strap, or temple arms attached thereto. The mounting means consist of a lightweight horizontal component which extends from the nose bridge and underneath the eyes. This component is located below the horizontal center of the eye and rests above the cheek area of the user's face. Illuminators, which are oriented approximately linear to the horizontal axis of the eye on the component, radiate light into the lower portion of the eye.

Abstract: The presently disclosed invention is a device for measuring horizontal and vertical eye movement. The device is adaptable to utilize multiple measurement technologies (e.g., direct infrared, electro-oculography, ultrasound, or video), and is capable of measuring each eye individually or both eyes jointly. The present invention overcomes the shortcomings of the prior art by requiring minimal adjustment for accurate measurement, only minimally obstructing the user's visual range (i.e., slightly more than the user's own nose), being made of low cost and readily available material, and by being comprised of a comfortable and efficient design of an adjustable nose and forehead piece with an adjustable head strap. An additional advancement over the prior art is that the presently disclosed device does not require an aperture or frame, as did the prior art, or any additional optics such as, lenses, mirrors, or prisms.
