Background

Ocular artefacts from blinks and eye movements remain a persistent obstacle to reliable electroencephalography (electroencephalography), particularly when dedicated electrooculography (electrooculography) electrodes are unavailable or undesirable.

Purpose

Objective.

Results

camera-based cleaning cut blink interference in half on frontal signals

true VEOG
More results

On VEOS-Dev, VEOS achieves median Pearson correlationr=0.81to ground-truth vertical EOG and median blink-onset timing error of 18 ms.

On Eye-BCI, the video-only model achieves medianr=0.74, outperforming an eye-tracker baseline.

More results

Cleaning preserves task-relevant electroencephalography structure, including motor imagery (motor imagery) mu/beta rhythms, steady-state visual evoked potentials (steady-state visual evoked potentials) spectral signal-to-noise ratio, and P300 morphology.

Conclusion

The validation was conducted on controlled recordings and should be interpreted as a best-case demonstration rather than a full validation in unconstrained wearable settings.
