ABSTRACT
In this study we propose and evaluate a novel approach that allows detection of physical eye fatigue. The proposed approach is based on the analysis of the recorded eye movements via what is called behavioral scores. These easy-to-compute scores can be obtained immediately after a calibration procedure, via processing of such basic eye movements as fixations and saccades extracted from the raw eye positional data recorded by an eye tracker. The results, based on the data from 36 volunteers indicate that one of the behavioral scores, Fixational Qualitative Score, is more sensitive to the onset of eye fatigue than already established methods based on saccadic characteristics only.

Detecting the onset of eye fatigue in a live framework
ETRA '16: Proceedings of the Ninth Biennial ACM Symposium on Eye Tracking Research & ApplicationsThis document describes a method for detecting the onset of eye fatigue and how it could be implemented in an existing live framework. The proposed method, which uses fixation data, does not rely as heavily on the sampling rate of the eye tracker as do ...
Eye&Head: Synergetic Eye and Head Movement for Gaze Pointing and Selection
UIST '19: Proceedings of the 32nd Annual ACM Symposium on User Interface Software and TechnologyEye gaze involves the coordination of eye and head movement to acquire gaze targets, but existing approaches to gaze pointing are based on eye-tracking in abstraction from head motion. We propose to leverage the synergetic movement of eye and head, and ...
Rule-based learning for eye movement type detection
MCPMD '18: Proceedings of the Workshop on Modeling Cognitive Processes from Multimodal DataEye movements hold information about human perception, intention, and cognitive state. Various algorithms have been proposed to identify and distinguish eye movements, particularly fixations, saccades, and smooth pursuits. A major drawback of existing ...
