In the eye of the beholder: A survey of gaze tracking techniques

作者：

Highlights：

• Gaze tracking is an important way to realize automated vision-based interaction

• Personal calibration and head motion are key issues of 2D gaze estimation

• 3D gaze estimation requires higher system configuration than other methods

• The factors that complicate the appearance restrict unconstrained gaze estimation

• Person, head pose and scene invariance is the goal pursued by gaze tracking
