START CONFIGURATOR

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:

  1. High-Quality, Mobile EEG Data: The g.Nautilus provides high-quality EEG signals while being fully wireless and easy to wear, making it ideal for both lab-based and real-world applications. This mobility enables users to collect EEG data without restricting natural movement, so eye-tracking can be seamlessly integrated in real-world or simulated environments.
  2. Contextualized Cognitive Monitoring: By pairing g.Nautilus with eye-tracking, you can connect specific brain states to precise visual stimuli or areas of focus. For example, g.Nautilus can track focus or mental workload, while eye-tracking pinpoints exactly what the person is looking at, providing a fuller picture of how they are processing information.
  3. Enhanced Real-Time BCI Applications: In brain-computer interface (BCI) systems, this combination allows for more robust and context-sensitive interactions. Eye-tracking data can help pinpoint a target location or area of interest, while EEG from g.Nautilus verifies mental intent, significantly improving BCI response time and accuracy.
  4. Naturalistic Experimentation: The g.Nautilus’s wireless setup allows participants to move freely, which is especially useful in studies where realistic, natural interactions are essential—such as in marketing, virtual reality, or navigation tasks. Eye-tracking provides additional insights into how people visually engage with their environment, while g.Nautilus records brain responses in real time.
  5. Advanced Neuromarketing and User Research: Combining g.Nautilus with eye-tracking is powerful for neuromarketing, where understanding both cognitive and emotional responses to visual content is key. Eye-tracking data reveals where a participant’s attention goes, while EEG shows their emotional or cognitive reactions, making it possible to evaluate how people respond to specific elements in advertisements or product designs.
  6. Improving Training and Safety: For training in fields like aviation, medicine, or manufacturing, this setup helps assess how well participants are processing visual information and managing cognitive load. The combination of real-time cognitive data from the g.Nautilus and eye-tracking allows for a highly individualized assessment, supporting safer and more effective learning experiences.

This integrated approach makes the g.Nautilus and eye-tracking combination especially valuable for researchers, trainers, and developers aiming to capture nuanced insights into cognitive processing, attention, and user interaction.
