Yes. Tobii Pro Spark offers precise software-based synchronization with external physiological measuring devices via the Tobii Pro SDK, but lacking dedicated TTL hardware synchronization. For multimodal behavioral research, this allows researchers to synchronize gaze data with tools like EEG, ECG, GSR, and other biosignal acquisition systems.

Software-Based Synchronization

Tobii Pro Spark supports software-based synchronization through:

• Tobii Pro SDK

This enables researchers to synchronize gaze data with:

• EEG

• ECG

• GSR

• Other biosignal acquisition systems

This supports multimodal behavioural research involving eye tracking and physiological measurements.

Time Synchronization

The tracker includes integrated synchronization between:

• Eye tracker time domain

• Host computer

This allows researchers to align gaze data with:

• Stimulus presentation software

• Physiological recordings

using shared timestamps.

TTL Hardware Synchronization

Tobii Pro Spark does not include:

• Dedicated TTL hardware synchronization

For laboratories requiring microsecond-level hardware triggering, Tobii Pro Spectrum may be preferred.

Research Applications

Tobii Pro Spark is sufficient for many experiments that rely on software synchronization, including:

• Psychology

• Education

• Human factors

Summary

Through the Tobii Pro SDK, Tobii Pro Spark facilitates software-based synchronization, allowing shared timestamps to synchronize gaze data with EEG, ECG, GSR, and other biosignal acquisition devices. Its integrated eye tracker-to-host computer time synchronization facilitates numerous multimodal investigations in psychology, education, and human factors research, even though it lacks specific TTL hardware synchronization.
