Free head motion eye gaze tracking without calibration
Abstract
This paper introduces a novel technique for remote eye gaze tracking and detection of point of regard that is specially designed for wide use in HCI. It addresses and eliminates two of the major problems of commercial remote eye gaze tracking, namely the need for user calibration before each session and of accuracy degradation with head movement. The new technique uses a single calibrated camera, several light sources with known positions and a physical model of the eye to estimate the 3D position of the eye and its gaze direction. Simulation results using ray tracing are used to study the accuracy and robustness of the system, and demonstrate its operability.
