ABSTRACT
While the video-based measurement of eye movements, also referred to as "video-oculography" (VOG), has many advantages, it also suffers from a serious disadvantage which has not been solved yet: using images of the eye, how can we distinguish between a movement of the eye-in-the-head on the one hand, and a movement of the camera with respect to the head on the other? To distinguish between the two, we need additional information about the orientation and position of the camera with respect to the head.

Non-Contact Eye Gaze Tracking System by Mapping of Corneal Reflections
FGR '02: Proceedings of the Fifth IEEE International Conference on Automatic Face and Gesture RecognitionIn this paper, we suggest a new system to estimate the direction of a user's eye gaze. Our system consisted of five IR LEDs and a CCD camera. The IR LEDs that are attached to the corners of a computer monitor make glints on the surface of the cornea of ...
Corneal Imaging System: Environment from Eyes
This paper provides a comprehensive analysis of exactly what visual information about the world is embedded within a single image of an eye. It turns out that the cornea of an eye and a camera viewing the eye form a catadioptric imaging system. We refer ...
Key Techniques of Eye Gaze Tracking Based on Pupil Corneal Reflection
GCIS '09: Proceedings of the 2009 WRI Global Congress on Intelligent Systems - Volume 02Eye 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 ...
