Description

When an eye tracking system is used in a car, user-calibration-free system is suitable because a driver can sometimes change. In addition, we usually look at the mirrors while driving a car, and so the system should track the driver’s gaze in a wide range. In this study, we proposed a new method that calculates the gaze directions in a wide range by improving a user-calibration-free gaze tracking method. Our new method changes the calculation method based on the detected number of feature points of the eye. We installed cameras and LEDs in a car simulator that used a real car in a laboratory based on a simulator for developing a gaze sensitive environment. The evaluation results of a developed system for one participant showed that the system could track gazes when the participant looked mirrors.
