Special Issue Information

Dear Colleagues,

With the rapid advancement of cheap eye trackers and image processing that enable the use of common cameras to track gaze, eye tracking technology has become ubiquitous and accessible. It is our belief that this represents significant potential for future research.

The purpose of this Special Issue is to gather valuable research that utilizes gaze information for different purposes. Today, there is a plethora of applications: medicine, user interfaces, accessibility, psychology, the advertising industry, and artificial intelligence, to name just a few. And, probably, new applications will emerge in the future.

It is important that eye-tracking technology should be easy to use and reliable. Therefore, we would like to invite the contribution of papers that cover the eye tracking methodology and ways for its improvement. Ideas on how to use gaze data and its applications are another important research topic that will be covered by this Special Issue.

The scope of the Special Issue includes, but is not limited to, the following:

  • Collecting eye movement data;
  • Accuracy and precision of data;
  • Calibration of eye movement data signal;
  • Events detection (fixations and saccades);
  • Gaze-based user interfaces;
  • Eye movement modelling;
  • Data mining of eye movement signal;
  • Eye movement-based identification;
  • Improving man–machine interactions;
  • Eye movement applications in testing interface usability;
  • Eye movement in security systems;
  • Usage of eye movement signal in cognitive processes;
  • Recognition of people's intentions based on their eye movement;
  • Miscellaneous eye tracking applications.

Eye movements are difficult to observe and replicate, making them a promising yet understudied modality for behavioral biometrics. This study is the first to examine the feasibility of using eye movement patterns during manga reading as a biometric identifier, leveraging the medium’s rich behavioral data from diverse reading behaviors. Eye movement data from 59 participants were recorded while they read two manga works on a screen. A comprehensive set of gaze features was extracted and evaluated using five machine learning classifiers, among which Random Forest (RF) consistently achieved the best performance. Under constrained experimental conditions, the RF classifier achieved a Rank-1 identification rate of 95.0% and an equal error rate (EER) of 1.9%. Furthermore, this study systematically investigated two critical challenges for practical deployment: stimulus dependency and template aging. Cross-stimulus evaluation revealed substantial performance degradation when training and testing used different manga works, and template aging analysis over an approximately 90-day interval demonstrated notable declines in identification accuracy. These results provide preliminary evidence supporting the potential of natural reading behaviors for biometric continuous authentication systems while highlighting the need for further research into cross-stimulus generalization and temporal stability.

Eye tracking has emerged as a valuable, non-invasive tool for identifying cognitive and motor abnormalities across a wide range of brain-related disorders. Recent studies have explored its utility in neurodevelopmental, neurological, and neurodegenerative conditions. This review synthesizes the findings of studies that apply eye movement analysis including fixation patterns, saccades, scanpaths, and pupil dynamics combined with machine learning (ML) and deep learning (DL) approaches for disease detection and classification. Particular attention is given to the design of eye-tracking tasks, feature extraction strategies, and algorithmic frameworks. Across clinical categories, models such as Support Vector Machines (SVM), random forests (RF), and Convolutional Neural Networks (CNN) have demonstrated promising diagnostic potential, with several studies reporting classification accuracies exceeding 80%, although performance varies depending on the task design, dataset characteristics, and validation methodology. These findings support the potential of eye movement-based biomarkers for early detection and clinical monitoring. Despite encouraging results, current research faces important limitations, including small sample sizes, a lack of standardization, and limited generalizability across populations. To advance clinical translation, future work should emphasize data augmentation, multimodal integration, external validation, and the use of explainable AI (XAI). Overall, eye movement analysis offers a scalable and objective pathway toward improving diagnostic precision in brain-related disorders. Full article
