ELEVATE NEUROMARKETING RESEARCH
Integrated EEG and Eyetracking Technology for Comprehensive Consumer Behavior and Cognitive Analysis
WEARABLE EEG AND EYE TRACKER
Using the g.Nautilus wearable EEG system in combination with Tobii Pro Glasses 3 offers a powerful and comprehensive solution for studying brain activity and behavior simultaneously in real-world environments. This integration enables researchers to capture high-quality EEG data while accurately monitoring eye movements and gaze patterns, providing deeper insights into cognitive and neural processes associated with visual attention, perception, and decision-making.
The lightweight and wireless design of all g.Nautilus wearable EEG headsets ensures that subjects can move naturally, enhancing the ecological validity of experiments. By synchronizing EEG and eye-tracking data, researchers can efficiently analyze how brain responses correspond to visual stimuli and behavioral actions in real-time. This combination is particularly valuable for neuromarketing, cognitive psychology, and other fields where understanding the connection between brain activity and visual engagement is essential.
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.
Combining the g.Nautilus wearable EEG headset with eye-tracking creates a highly versatile toolset for understanding complex brain and behavior relationships. Here’s why this specific combination is so effective:
