fNIRS + Eye Tracking Integration: Cortivision and Tobii Pro

Eye tracking and functional Near-Infrared Spectroscopy (fNIRS) represent a new chapter in multimodal research. By pairing the accurate, reliable measurement of eye movements with relative changes in cortical hemoglobin concentration, researchers can unlock a comprehensive understanding of human behavior in highly mobile, non-stationary scenarios. Hardware Synergy: Cortivision & Tobii Pro. Cortivision has addressed the growing need for high-fidelity, non-invasive multimodal solutions by ensuring seamless compatibility with Tobii Pro Glasses 3. Ultra-Light & Portable: The Tobii Pro Glasses 3 are lightweight and perfectly tailored for real-life neuroscience paradigms without adding restrictive weight to the participant's head., Zero Interference: Cortivision's fNIRS caps (such as the Photon Cap or Spectrum C23) are designed to perfectly accommodate the sleek frame of the Tobii Glasses, ensuring smooth data collection and significantly reducing participant discomfort., High-Definition Capture: With 8 infrared illuminators and 2 eye-tracking cameras per eye, combined with a high-definition scene camera, researchers get unparalleled insight into visual fixations alongside the fNIRS hemodynamic response. Precise Synchronization via LSL:. Multimodal data is only as good as its timing. The Cortivision CortiView and CortiPrism software suites provide precise, millisecond-accurate synchronization with Tobii data streams using the Lab Streaming Layer (LSL) protocol, eliminating complex manual alignment during post-processing. Key Applications for Real-Life Neuroscience:. This integrated multimodal approach delivers a more precise understanding of brain activity than either method in isolation, making it ideal for:. Movement Studies & MoBI: Studying cognitive-motor interactions, sports science, and rehabilitation in dynamic environments., Cognitive Neuroscience: Transitioning classic stationary paradigms into realistic, visually rich environments., Ergonomics & Decision Making: Assessing mental workload and visual focus in dynamic workplaces and cockpits., Education & Neurodevelopment: Utilizing naturalistic, non-threatening setups to study learning processes and neurocognitive development in children., VR & BCI: Combining eye-tracking inputs and fNIRS signals to decode neural intent for Brain-Computer Interfaces in extended reality.
