Gaze estimation in a gaze tracking system

Science China Information Sciences, 2011
This article presents a gaze estimation method (GEMHSSO) based on the pupil center cornea reflection (PCCR) technique. Existing PCCR systems suffer from several problems, including the restriction of users’ head movement, and the requirement of individual calibration.

Keypoint-Based Gaze Tracking

2021
Effective assisted living environments must be able to perform inferences on how their occupants interact with their environment. Gaze direction provides strong indications of how people interact with their surroundings. In this paper, we propose a gaze tracking method that uses a neural network regressor to estimate gazes from keypoints and integrates

Gaze-tracked crowdsourcing

2015 10th International Workshop on Semantic and Social Media Adaptation and Personalization (SMAP), 2015
When creating intelligent systems, we often need proper knowledge bases and resources annotated with metadata. Sometimes, we have no other option, than to utilize crowdsourcing, to acquire the data in necessary quantity. Crowdsourcing is a costly endeavor, always with space for improvements in task solving quantity and quality.

GAZEL: Runtime Gaze Tracking for Smartphones

2021 IEEE International Conference on Pervasive Computing and Communications (PerCom), 2021
Although work has been conducted on smartphone gaze tracking, the existing techniques are not pervasively used because of their heavy weight and low accuracy. Our preliminary analysis shows that these techniques would work better if their models were trained with data from tablets which have large screens.

Dynamic predictions of tracked gaze

Seventh International Symposium on Signal Processing and Its Applications, 2003. Proceedings., 2003
We present a model for predicting the eye-movements of observers who is viewing dynamic sequences of images. As an indicator for the degree of saliency we evaluate an invariant of the spatio-temporal structure tensor that indicates an intrinsic dimension of at least two. The saliency is used to derive a list of candidate locations.
