Apparatus to Detect and Measure Saccade and Pupillary Changes (US 7380938)

Photonics Spectra
Nov 2008
A tracking system has been developed that employs a first-line camera to track horizontal eye motion and a second-line camera to track vertical eye motion. The output signals from both camera processors identify and track eye motion using a correlation or edge detection algorithm on boundaries between the sclera, iris and pupil. Eye-motion data is compared with that of a model to obtain a measure of fitness for the individual.
Applications: Public safety; employee monitoring; gaming and computer interfaces for the disabled.

A light-tight box that receives light from an object or scene and focuses it to form an image on a light-sensitive material or a detector. The camera generally contains a lens of variable aperture and a shutter of variable speed to precisely control the exposure. In an electronic imaging system, the camera does not use chemical means to store the image, but takes advantage of the sensitivity of various detectors to different bands of the electromagnetic spectrum. These sensors are transducers...
tracking system
A controlled motion system that may use a telescope, camera or antenna to follow accurately a satellite, missile, vehicle or other device in response to radar, radio or computer signals.
