Eye movement analysis in modern 3D rendering systems is reviewed and three new techniques are derived inspired by work developed in early Virtual Reality so-called 2.5D implementations, namely (a) gaze depth (i.e., vergence) estimation, (b) vergence calibration, and (c) real-time 3D event detection that considers eye- and head-coupling. The new 3D calibration shows excellent error reduction in terms of Mean Squared Error (MSE).
