Friedman L, Komogortsev O
PLoS One
. 2024 Sep;
19(9):e0310436.
PMID: 39283870
Our interest was to evaluate changes in fixation duration as a function of time-on-task (TOT) during a random saccade task. We employed a large, publicly available dataset. The frequency histogram...

PMID: 38957346
In a prior report (Raju et al., 2023) we concluded that, if the goal was to preserve events such as saccades, microsaccades, and smooth pursuit in eye-tracking recordings, data with...

PMID: 38957345
The Fourier theorem states that any time-series can be decomposed into a set of sinusoidal frequencies, each with its own phase and amplitude. The literature suggests that some frequencies are...

PLoS One
. 2024 Jan;
19(1):e0291823.
PMID: 38166054
In this study, we provide a detailed analysis of entropy measures calculated for fixation eye movement trajectories from the three different datasets. We employed six key metrics (Fuzzy, Increment, Sample,...

GazeBaseVR, a large-scale, longitudinal, binocular eye-tracking dataset collected in virtual reality
Lohr D, Aziz S, Friedman L, Komogortsev O
Sci Data
. 2023 Mar;
10(1):177.
PMID: 36997558
We present GazeBaseVR, a large-scale, longitudinal, binocular eye-tracking (ET) dataset collected at 250 Hz with an ET-enabled virtual-reality (VR) headset. GazeBaseVR comprises 5,020 binocular recordings from a diverse population of...

PMID: 36034311
Background: Nystagmus identification and interpretation is challenging for non-experts who lack specific training in neuro-ophthalmology or neuro-otology. This challenge is magnified when the task is performed telemedicine. Deep learning models...

Behav Res Methods
. 2022 Apr;
55(1):417-427.
PMID: 35411475
Manual classification of eye-movements is used in research and as a basis for comparison with automatic algorithms in the development phase. However, human classification will not be useful if it...

J Eye Mov Res
. 2021 Nov;
14(3).
PMID: 34745443
This paper is a follow-on to our earlier paper (7), which focused on the multimodality of angular offsets. This paper applies the same analysis to the measurement of spatial precision....

PMID: 34122749
Typically, the position error of an eye-tracking device is measured as the distance of the eye-position from the target position in two-dimensional space (angular offset). Accuracy is the mean angular...
