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.
