Real-Time EEG Cap Electrode Detection for Guided Point-of-Care Placement
A camera that watches you put on an EEG cap and catches mistakes instantly
Researchers built a vision system that watches a webcam feed in real time to detect electrodes on an EEG cap and check whether they're placed in the right spots on the head. The system correctly identified electrode positions 94–97% of the time across different cap sizes and subjects, and runs fast enough on a regular computer to guide placement as it happens.
EEG tests require electrodes to be placed at precise locations on the scalp—mistakes mean bad data and wasted time. This system lets technicians see immediately whether electrodes are in the right position, reducing errors and training time. It works on standard laptops and cameras, making it practical for clinics and research labs that can't afford specialized equipment.
