What Types of Data Can Tobii Pro Fusion Record and Analyze?

An infographic titled 'Eye Tracking Outputs' displaying various eye tracking metrics including gaze position, fixations, blink events, areas of interest (AOIs), attention metrics, scan paths, heatmaps, and gaze videos. The diagram shows a central com

Researchers can study visual attention, perception, cognition, and behavior by recording a wide range of eye movement and physiological measures with Tobii Pro Fusion. Binocular gaze location, gaze origin, pupil diameter, timestamps, and eye openness are the main outputs, all of which are synchronized at the chosen sampling frequency of up to 250 Hz.

Eye Tracking Data

Tobii Pro Fusion records:

  • Binocular gaze position

  • Gaze origin

  • Pupil diameter

  • Timestamps

  • Eye openness

These measurements are synchronized at the selected sampling frequency of up to 250 Hz.

Behavioural Metrics

Researchers can derive a wide variety of behavioural metrics, including:

  • Fixations

  • Saccades

  • Smooth pursuit

  • Dwell time

  • Revisit counts

  • Blink behaviour

  • Pupil dilation

  • Gaze transitions

  • Scan paths

  • Visual search patterns

These metrics support research in:

  • Psychology

  • Neuroscience

  • Reading

  • Human factors

  • Consumer behaviour

  • Education

  • Usability testing

Eye Openness & Eye Image Data

In addition to gaze data, Tobii Pro Fusion provides:

Eye Openness Data

  • Individual eye openness data for each eye

Eye Image Streams

Researchers can also access:

  • Eye image streams

These image streams can be used for:

  • Data validation

  • Algorithm development

Data Analysis in Tobii Pro Lab

When paired with Tobii Pro Lab, researchers can generate:

  • Heat maps

  • Gaze plots

  • Areas of Interest (AOIs)

  • Time of Interest (TOIs)

  • Participant comparisons

  • Fixation statistics

Researchers can also:

  • Export raw datasets

for further analysis in:

  • MATLAB

  • Python

  • R

  • SPSS

  • Custom software

Summary

At sampling frequencies of up to 250 Hz, Tobii Pro Fusion captures synchronized binocular gaze location, gaze origin, pupil diameter, timestamps, and eye openness. In addition to exporting raw datasets for additional analysis in MATLAB, Python, R, SPSS, or custom software, Tobii Pro Lab allows researchers to examine eye movement behavior utilizing heat maps, gaze plots, AOIs, TOIs, participant comparisons, and fixation statistics.
