Eye Tracker Accuracy: Quantitative Evaluation of the Invisible Eye Center Location [PDF]
arXiv, 2017 Purpose. We present a new method to evaluate the accuracy of an eye tracker based eye localization system. Measuring the accuracy of an eye tracker's primary intention, the estimated point of gaze, is usually done with volunteers and a set of fixation points used as ground truth. However, verifying the accuracy of the location estimate of a volunteer's

Your Eyes Say You're Lying: An Eye Movement Pattern Analysis for Face Familiarity and Deceptive Cognition [PDF]
arXiv, 2018 Eye movement patterns reflect human latent internal cognitive activities. We aim to discover eye movement patterns during face recognition under different cognitions of information concealing. These cognitions include the degrees of face familiarity and deception or not, namely telling the truth when observing familiar and unfamiliar faces, and ...

A review on methods used to record and analyze microfluctuations of the accommodation in the human eye [PDF]
Journal of the European Optical Society-Rapid Publications, 2011 In steady state conditions, the accommodation of the human eye presents fluctuations. These fluctuations, called microfluctuations, are described in the literature as having an amplitude of less than 1D and a frequency up to a few Hz.

Spherical refractive correction with an electro-optical liquid lens in a double-pass system [PDF]
Journal of the European Optical Society-Rapid Publications, 2013 In this study we show a novel double-pass configuration to correct the spherical refractive error by means of an electro-optical liquid lens. The proposed method enables spherical correction in the −12 D to +7 D range without movable parts using an ...

Gaze Estimation with Eye Region Segmentation and Self-Supervised Multistream Learning [PDF]
arXiv, 2021 We present a novel multistream network that learns robust eye representations for gaze estimation. We first create a synthetic dataset containing eye region masks detailing the visible eyeball and iris using a simulator. We then perform eye region segmentation with a U-Net type model which we later use to generate eye region masks for real-world eye ...

Real-time Eye Gaze Direction Classification Using Convolutional Neural Network [PDF]
arXiv, 2016 Estimation eye gaze direction is useful in various human-computer interaction tasks. Knowledge of gaze direction can give valuable information regarding users point of attention. Certain patterns of eye movements known as eye accessing cues are reported to be related to the cognitive processes in the human brain.
