Abstract (EN): This work presents a free head eye-tracking solution created for use as a complementary tool in the parameterization of cochlear implants. Nowadays, the parameterization of these implants is a long and cumbersome process performed by audiologists and speech therapists that throughout many periodic evaluations where audiometric tests and electrode adjustments are performed. The eye tracking system will assist this process through detection of saccades generated when a subject hears sounds produced during the audiometric test procedure. The main purpose is to ease and improve the implant re-parameterization procedure with uncooperative subjects, like children. The developed system is composed of three digital video cameras where two of the cameras are responsible of the detection of the position of the face and eyes and the third is responsible of the gaze detection. The developed face and eye detectors are also compared in order to choose the best combination of algorithms to perform robust eye detection with unpredictable subjects. The best combination of algorithms is the Viola-Jones face detector combined with an eye detector Ring Gabor filters, that correctly detected the eye-position in 76,81% of the tested videos at 18 frames per second.
