HIGH-DENSITY EEG & EYE TRACKING FOR COGNITIVE NEUROSCIENCE
Synchronize high-density EEG, gaze behavior, pupil dynamics, and scene video within one integrated research platform for cognitive neuroscience, Brain-Computer Interfaces, visual attention, human factors, neuromarketing, and neuroergonomics.
SIMULTANEOUS EEG AND EYE TRACKING RECORDINGS
The combination of g.HIamp and Tobii Pro Fusion enables synchronized acquisition of high-density EEG, gaze behavior, pupil dynamics, and eye movements within one integrated research platform. Researchers can investigate how neural activity relates to visual attention, perception, decision-making, and cognitive workload with exceptional temporal precision and high spatial resolution that cannot be obtained from either technology alone.
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, pupil dynamics, and visual stimuli.
With support for up to 256 EEG channels, the platform is ideally suited for cognitive neuroscience, Brain-Computer Interfaces, visual neuroscience, human factors, neuroergonomics, neuromarketing, and neurorehabilitation. High-density EEG combined with precise gaze information enables detailed investigation of cortical activity during natural and controlled visual tasks.

REAL-TIME SYNCHRONIZATION & OPEN SOFTWARE ECOSYSTEM
g.HIsys Professional synchronizes EEG, gaze data, and eye-tracking events in real time, enabling acquisition, visualization, feature extraction, feature extraction, signal processing, machine learning, and Brain-Computer Interface development within a single software environment. g.BSanalyze provides comprehensive offline analysis of synchronized EEG and gaze recordings, allowing researchers to investigate event-related potentials, fixation events, saccades, and cognitive responses.
Together with Python, MATLAB, Simulink, and Lab Streaming Layer (LSL) support, the platform integrates seamlessly with virtual reality, motion capture, robotics, physiological sensors, and custom neuroscience applications.
REAL-TIME EYE TRACKING IN SIMULINK
The Tobii Pro Simulink Interface extends g.HIsys Professional with synchronized acquisition of EEG, gaze position, pupil dynamics, fixation events, saccades, smooth pursuit, and ocular behavior for real-time neuroscience applications. Researchers can rapidly develop Brain-Computer Interfaces, visual attention experiments, eye movement analysis, fixation analysis, visual search paradigms, custom gaze pattern analysis, closed-loop experiments, and advanced signal processing workflows directly within the Simulink environment.
Compatible with g.HIamp, g.USBamp, and g.Nautilus, the interface supports Tobii Pro Fusion, Tobii Pro Spectrum, Tobii Pro Spark, and Tobii Pro X3-120 eye trackers. Ready-to-use example models simplify synchronized acquisition, visualization, and processing of EEG, gaze coordinates, fixation events, saccades, pupil dilation, gaze patterns, and ocular behavior, allowing laboratories to focus on neuroscience research instead of software integration.
VALIDATING SOCIAL CAMPAIGNS WITH EEG & EYE TRACKING
Researchers have demonstrated that combining synchronized EEG and eye tracking provides objective insights into how people perceive, process, and remember visual content. Rather than relying solely on questionnaires, brain activity and gaze behavior reveal both conscious and subconscious responses to advertisements, games, and interactive media.
In one study, synchronized EEG and eye tracking were used to evaluate how participants responded to social campaign messages embedded in computer games. The combination of neural activity, gaze behavior, and questionnaire data enabled researchers to measure attention, visual processing, engagement, and message recall simultaneously. The results showed that this integrated approach provides a comprehensive framework for evaluating advertising effectiveness and user engagement in interactive environments.
This approach is increasingly used in neuromarketing, user experience research, cognitive neuroscience, human factors, and visual attention studies, where understanding both where people look and how the brain responds leads to more objective evaluation than behavioral observations alone.
