A Calibration-Free Gaze Tracking Technique
We propose a novel method to estimate and track the 3D line of sight of a person based on 3-D computer vision techniques. Most of the existing nonintrusive gaze tracking methods share a common drawback: users have to perform certain experiments in calibrating the user-dependent parameters before using the gaze tracking systems. These parameters are functions of the radius of the cornea, the pos...
متن کاملGaze Tracking System for User Wearing Glasses
Conventional gaze tracking systems are limited in cases where the user is wearing glasses because the glasses usually produce noise due to reflections caused by the gaze tracker's lights. This makes it difficult to locate the pupil and the specular reflections (SRs) from the cornea of the user's eye. These difficulties increase the likelihood of gaze detection errors because the gaze position i...
متن کاملA Model-Based Gaze Tracking System
In this paper we present a non-intrusive model-based gaze tracking system. The system estimates the 3-D pose of a user’s head by tracking as few as six facial feature points. The system locates a human face using a statistical color model without any mark on the face and then finds and tracks the facial features, such as eyes, nostrils and lip corners. A full perspective model is employed to ma...
متن کاملDeep eye fixation map learning for calibration-free eye gaze tracking
The existing eye trackers typically require an explicit personal calibration procedure to estimate subject-dependent eye parameters. Despite efforts in simplifying the calibration process, such a calibration process remains unnatural and bothersome, in particular for users of personal and mobile devices. To alleviate this problem, we introduce a technique that can eliminate explicit personal ca...
