Abstract :
Eye Gaze Tracking (EGT) is a kind of techniques that can estimate gaze direction of a person via various methods such as optics, electronics, mechanics etc. Pupil corneal reflection is one of those methods that using the vector from Purkinje image center location to pupil center location to estimate the gaze direction. A review on key techniques of EGT based on pupil corneal reflection is given in three aspects of eye feature detection, mapping model from gaze parameters to gaze direction and face pose estimation. The characteristics of two kind mapping models are analyzed and the detection method of gaze direction based on stereovision is discussed. According to a large number of recent references, we propose some major problems and their possible solutions in EGT techniques as well as its research orientation in future.
