A Study on the Sensitivity of Illumination Source in the Geometerical Eye-Gaze Model

Enhancement of computing ability of the smart phones the new use of the said device focus on the eye gaze estimation. The geometrical eye gaze estimation method measure the relation between camera, user’s eye and smart device. The illumination source on smart device generate glint on capture pupil image of the user’s eye. From the relation of glint and pupil center the eye gaze position is captured. Slight variation on light source position will drastically reduce the accuracy of the system. This research paper proposed a method to reduce the noise at light source position. The results shows significant performance and reduce the noise at light source location with 1 degree angular error.
