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. Sensors, which are above and below the illuminators on the component, detect and measure the amount of reflected light. The device is capable of measuring both axes independently and jointly, as well as both eyes independently and jointly. Utilizing a robust alg…
