Can Tobii Pro Spectrum Be Integrated with EEG, fNIRS, EMG, MEG, or Other Physiological Measurement Systems?

Research participant using Tobii Pro Spectrum and Bitbrain EEG for synchronized eye tracking and brain activity research

Yes. Tobii Pro Spectrum is one of the best eye trackers for synchronization with physiological measuring devices because it was created especially to facilitate multimodal neuroscience and behavioral research. Eye movement data may be precisely synchronized with brain activity, muscle activity, physiological reactions, and external experimental events thanks to the tracker's hardware and software-based synchronization options.

Hardware-Based Synchronization

For hardware synchronization, Tobii Pro Spectrum includes a dedicated 8-bit TTL input port capable of receiving:

  • 256 unique event codes

The system provides:

  • Timestamp accuracy of approximately 50 microseconds

This enables highly precise synchronization with:

  • EEG amplifiers

  • fNIRS systems

  • MEG systems

  • EMG equipment

  • Physiological acquisition hardware

  • Stimulus presentation systems

In addition, integrated tracker-to-computer time synchronization achieves approximately:

  • 100 microseconds accuracy

This further improves temporal alignment across connected devices.

Software-Based Synchronization

Software synchronization is supported through:

  • Tobii Pro Lab

  • Tobii Pro SDK

Researchers can:

  • Insert event markers

  • Synchronize experimental events

  • Stream gaze data alongside external software

Research Applications

These synchronization capabilities make Tobii Pro Spectrum well suited for:

  • Cognitive neuroscience

  • Psychophysiology

  • Human factors engineering

  • Motor control research

  • Clinical investigations

where eye tracking forms part of a larger multimodal measurement framework.

Summary

Tobii Pro Spectrum may be synchronized with physiological measurement devices using both software and hardware. Researchers can precisely synchronize eye movement data with EEG, fNIRS, EMG, MEG, physiological acquisition hardware, and stimulus presentation systems for advanced multimodal neuroscience and behavioral research using its 8-bit TTL input port, 256 distinct event codes, approximately 50 microsecond timestamp accuracy, approximately 100 microsecond tracker-to-computer time synchronization, Tobii Pro Lab, and Tobii Pro SDK.
