WEARABLE EEG & EYE TRACKING FOR REAL-WORLD NEUROSCIENCE
Capture synchronized EEG, gaze behavior, pupil dynamics, and scene video with one integrated platform for multimodal brain imaging, cognitive neuroscience, Brain-Computer Interfaces, human factors, neuromarketing, and naturalistic research.
SYNCHRONIZED EEG & EYE TRACKING
The combination of g.Nautilus and Tobii Pro Glasses 3 enables synchronized recording of high-quality EEG, gaze behavior, pupil dynamics, and scene video within one integrated wearable platform. Researchers can investigate how brain activity relates to visual attention, perception, decision-making, and cognitive workload in both laboratory and real-world environments. Fully synchronized EEG and eye-tracking data provide a comprehensive view of human cognition for Brain-Computer Interfaces, cognitive neuroscience, human factors, neuroergonomics, neuromarketing, and user experience research.
EEG reveals when neural activity occurs, while eye tracking identifies where visual attention is directed. Combining both modalities allows researchers to relate brain responses directly to gaze behavior, fixations, saccades, and visual stimuli. The wireless design of g.Nautilus enables natural movement, making the platform ideal for real-world neuroscience, virtual reality, driving simulation, psychology, aviation, medicine, and other applications requiring ecologically valid experiments.
The Tobii Pro Glasses 3 interface for g.HIsys Professional and Simulink enables synchronized acquisition of EEG, gaze data, and scene video within a single workflow. Experiments can be calibrated, recorded, visualized, and processed in real time, while Tobii Pro Lab and g.BSanalyze support advanced offline analysis of synchronized gaze events, pupil dynamics, eye movements, and EEG signals. Support for Python, MATLAB, Simulink, and Lab Streaming Layer (LSL) enables seamless integration with custom Brain-Computer Interfaces and multimodal neuroscience experiments.

SYNCHRONIZED EEG & EYE TRACKING
The combination of g.Nautilus and Tobii Pro Glasses 3 enables synchronized recording of EEG, gaze behavior, pupil dynamics, and scene video within one integrated wearable platform. Researchers can investigate how neural activity relates to visual attention, eye movements, perception, decision-making, and cognitive workload during both laboratory and real-world experiments.
Compatible with g.Nautilus RESEARCH, g.Nautilus MULTI-PURPOSE, and g.Nautilus PRO FLEXIBLE, the lightweight wireless system allows participants to move naturally while maintaining precise synchronization between EEG and eye-tracking data. This makes the platform ideal for Brain-Computer Interfaces, cognitive neuroscience, neuromarketing, neuroergonomics, human factors, virtual reality, psychology, and user experience research.
UNDERSTANDING HUMAN BEHAVIOR
g.Nautilus and Tobii Pro Glasses 3 support a wide range of neuroscience and human behavior research applications by synchronizing brain activity with gaze behavior in real time. Researchers investigate visual attention, perception, and decision-making in cognitive neuroscience, develop hybrid Brain-Computer Interfaces that combine EEG and eye tracking, and evaluate attention, engagement, and cognitive workload in neuromarketing and user experience studies.
The wearable design also enables naturalistic experiments in human factors, neuroergonomics, virtual and mixed reality, and human-computer interaction, where synchronized EEG and eye-tracking data provide unique insights into how people perceive, process, and interact with complex environments. By combining neural activity with precise gaze information, researchers gain a more complete understanding of cognitive processing during real-world behavior.
TOBII PRO GLASSES 3 INTERFACE
The Tobii Pro Glasses 3 Interface block in Simulink manages the device’s acquisition state, enabling control over start/stop functions and synchronization of video and gaze data with EEG. Calibration can be done via Simulink or the Tobii Pro Glasses 3 application before running the model. To operate, create a Simulink model from the Tobii Pro Glasses 3 Demo template, connect the recording unit via Wi-Fi, and perform a quick calibration with a card placed 0.5-1.0 meters away.
For video synchronization, Tobii Pro Lab software can synchronize live scene view events (such as gaze on objects) with EEG data using a synchronization signal from the Tobii Pro Glasses 3 connected to an input on the biosignal amplifier. Events recorded in Tobii Pro Lab can be exported and imported into g.BSanalyze for further offline processing and analysis, enhancing the integration of gaze and EEG data for research applications.
