Researchers may study visual attention, cognitive processing, perception, and neurological function with remarkable detail because to Tobii Pro Spectrum's extensive collection of eye movement data. Fundamentally, the system synchronizes high-precision timestamps, pupil diameter, eye openness, binocular gaze location, and gaze origin at sampling frequencies between 60 and 1200 Hz.

Eye Tracking Data

Tobii Pro Spectrum records:

  • Binocular gaze position

  • Gaze origin

  • Pupil diameter

  • Eye openness

  • High-precision timestamps

These measurements are synchronized at sampling frequencies ranging from:

  • 60 Hz

  • 120 Hz

  • 150 Hz

  • 300 Hz

  • 600 Hz

  • 1200 Hz

This data provides the foundation for analyzing:

  • Fixations

  • Saccades

  • Smooth pursuit movements

  • Micro-saccades

  • Ocular tremors

  • Blink behaviour

  • Pupillary responses

Eye Openness & Eye Image Data

In addition to gaze data, Tobii Pro Spectrum provides:

Eye Openness Data

Individual eye openness data for each eye, making the system suitable for:

  • Fatigue studies

  • Blink analysis

  • Vigilance research

  • Cognitive workload investigations

Eye Image Streams

Researchers can also access:

  • Zoomed-in eye images during tracking

  • Full-frame camera images during gaze recovery

These image streams can be useful for:

  • Validating data quality

  • Developing custom image-processing algorithms

Data Analysis in Tobii Pro Lab

When combined with Tobii Pro Lab, researchers can transform raw measurements into meaningful behavioural metrics.

The software supports:

  • Heat maps

  • Scan paths

  • Gaze plots

  • Areas of Interest (AOIs)

  • Time of Interest (TOIs)

  • Fixation statistics

  • Visit counts

  • Dwell times

  • Participant comparisons

These analyses help researchers understand:

  • Where participants looked

  • How visual attention evolved throughout an experiment

Data Export & Advanced Analysis

For laboratories performing advanced statistical or computational analysis, Tobii Pro Spectrum supports exporting:

  • Raw gaze data

  • Associated metadata

through the Tobii Pro SDK.

This enables researchers to analyze data using:

  • MATLAB

  • Python

  • R

  • SPSS

  • Custom machine learning workflows

making the system suitable for both conventional behavioural research and cutting-edge computational neuroscience.

Summary

At sampling frequencies between 60 Hz and 1200 Hz, Tobii Pro Spectrum captures synchronized binocular gaze location, gaze origin, pupil diameter, eye openness, high-precision timestamps, and eye image streams. In addition to exporting raw gaze data and metadata for further analysis in MATLAB, Python, R, SPSS, or custom machine learning workflows, Tobii Pro Lab and the Tobii Pro SDK allow researchers to visualize eye movement behavior using heat maps, scan paths, gaze plots, AOIs, TOIs, fixation statistics, visit counts, dwell times, and participant comparisons.
