A low-cost implementation of an eye tracking system for driver's gaze analysis

We present an eye tracking system developed to study the driver's gaze behavior while driving a car. Two main challenges distinguish this project from similar works with analogous purposes: (1) the use of a cheap portable remote eye tracker, normally employed for indoor applications in controlled light conditions; and (2) the use of an ordinary webcam to shoot the road in front of the car. The purpose is to generate a video where the driver's fixations are graphically and dynamically superimposed on the road shot by webcam (taking into account the different viewpoints of driver and camera). The carried-out experiments confirmed that the implemented system, while perfectible, fulfills the requirements initially set.
