“…The numerical simulations use system parameters (position of light sources and camera parameters) that are similar to the parameters of the two-camera remote PoG estimation system described in [13]. The eye parameters are as follows: interpupillary distance = 60 mm; radius of curvature of the cornea = 7.8 mm; pupil radius = 4 mm; distance between the center of the pupil and the center of curvature of the cornea = 4.5 mm.…”

“…White Gaussian noise with a standard deviation of 0.1 pixels (similar to the noise observed in the experimental system described in [13]) was then added to the coordinates of the projected features (corneal reflection images (u ij ), pupil boundary image points). An ellipse was fitted to the noise-corrupted pupil boundary points in each camera image and its center (center of the pupil image) was used as an estimate of the image of the pupil center (u p,j ).…”

“…(Hennessey et al, 2006) and (Guestrin & Eizenman, 2006) demonstrate geometric gaze estimation methods using a single camera and four and nine calibration points, respectively. More recent studies have been presented by (Villanueva & Cabeza, 2007) and (Guestrin & Eizenman, 2008). The aforementioned methods employ 3-D eye models and calibrated scenarios (calibrated camera, light sources, and camera positions) to estimate LoS.…”

“…This is typically done by having the subject to fixate on multiple points with known locations in the scene. This might be an obstacle in applications requiring minimal subject cooperation, such as applications with infants [7]. In a commercial state-of-the-art system, the subject-specific calibration will take up to 5 minutes [20].…”
