Abstract :
An infrared-based eye tracker system was designed and implemented for recording saccades from both eyes simultaneously, and stored on a computer´s hard disk. The system uses infrared emitters to generate a narrow band infrared signal. An array of ten photo-detectors record the reflectance patterns from each eye. Data acquisition is made using LabView and a multiple linear regression algorithm is used to calibrate the system.
