Motion-corrected eye tracking (MoCET) improves gaze accuracy during visual fMRI experiments

Dataset Description: MoCET Study – Head Motion Parameters and Eye Tracking Data

This dataset contains the head motion parameters and eye tracking data used in the Motion-Corrected Eye Tracking (MoCET) study, which investigates the impact of head motion on gaze accuracy in fMRI experiments and proposes a method for drift correction.

Contents:

• Head motion parameters (*.tsv): Six-degree-of-freedom (6 DoF) motion estimates derived from fMRI preprocessing, including translations (X, Y, Z) and rotations (pitch, yaw, roll).
  • ex) sub-003_ses-07R_task-mcHERDING_run-1_desc-confounds_timeseries.tsv
• Pupil data (*.csv): Raw pupil coordinates recorded at high temporal resolution.
  • ex) sub-003_ses-07R_task-mcHERDING_run-1_recording-eyetracking_physio_log.csv
• Eye tracking (*.txt): Data file (_dat) logs the time interval between video frames and is used to match video frames to actual time. History file (_his) logs the TTL signal from the MRI scanner and is used to match eye tracking data to fMRI data

  • sub-003_ses-07R_task-mcHERDING_run-1_recording-eyetracking_physio_his.txt

Usage:

This dataset can serve as a benchmark for evaluating eye tracking drift correction methods and is particularly useful for:

• Investigating head motion-induced gaze errors in fMRI experiments.
• Validating motion correction techniques for high-precision eye tracking.
• Developing and testing new algorithms for eye tracking in neuroimaging research.

Restrictions:

• Neuroimaging and gameplay data are not included due to privacy and storage constraints.
• This dataset is intended for research purposes only.
