Generated: 2026-02-22T10:09:19.109653+00:00

Setup: Eye at (0, 550, 350) mm, camera at origin, light at (200, 0, 350) mm
Gaze model: Cerrolaza 2008 symmetric 2nd-order polynomial
Calibration: 9 points (3x3) | Fixed gaze target at center
Decentration model: Wildenmann 2013 (baseline 4.75 mm)

Gaze estimation error = angular distance (degrees) between estimated and true gaze point

Calibration error: 0.2698° mean, 0.3880° max
