Consumer-grade EEG-based Eye Tracking
Progress in consumer-grade electroencephalography–eye-tracking (EEG-ET) research has been hindered by the scarcity of high-quality, time-synchronized multimodal data. Method: This work introduces and publicly releases the first large-scale, multi-paradigm, standardized benchmark dataset for consumer-grade EEG-ET synchronization. It comprises 113 participants, 116 sessions, and 11.75 hours of high-fidelity synchronized recordings—acquired using low-cost commercial EEG systems (e.g., OpenBCI) and webcam-based eye trackers—spanning four oculomotor paradigms: saccades, smooth pursuit, fixation, and free viewing. All data undergo rigorous temporal alignment, bandpass filtering, and missing-value imputation; accompanying open-source preprocessing and analysis code is provided. Contribution/Results: The dataset substantially lowers hardware barriers for EEG-ET research, enhances reproducibility, and provides critical empirical support for gaze decoding under challenging conditions—including low-light environments and camera-free settings.
