What Types of Data Can Tobii Pro Glasses 3 Record and Analyze?

Infographic showing eye tracking outputs including gaze position, fixations, saccades, pupil diameter, blink events, Areas of Interest (AOIs), scan paths, heatmaps, gaze videos, and cognitive indicators.

Researchers can learn not only where participants gaze but also how they interact with their surroundings over time thanks to the extensive set of synchronized data streams captured by Tobii Pro Glasses 3. The system is appropriate for behavioral research, neurology, human factors engineering, usability testing, healthcare, and consumer research because of its multimodal dataset.

Eye Tracking Data:

The primary output consists of binocular gaze data, including:

  • Gaze coordinates

  • Gaze vectors

  • Fixation locations

  • Saccades

  • Eye movement events

The system also measures:

  • Absolute pupil diameter

This enables researchers to investigate changes in pupil size that may be associated with:

  • Cognitive workload

  • Emotional responses

  • Mental effort

  • Environmental conditions

Because gaze and pupil measurements are synchronized with timestamps, researchers can accurately relate eye movement behaviour to specific events occurring during an experiment.

Scene Video & Audio Recording:

In addition to eye tracking, Tobii Pro Glasses 3 records:

  • Full HD first-person scene video

  • Integrated 16-bit mono audio

This creates a complete visual and auditory record of the participant's experience.

The recorded data allows researchers to:

  • Review recordings

  • Verify participant behaviour

  • Conduct retrospective interviews

  • Annotate important events during post-processing

Motion Sensor Data:

Integrated inertial sensors simultaneously capture head movement, including:

  • Accelerometer

  • Gyroscope

  • Magnetometer

These sensors provide valuable information for studies involving:

  • Navigation

  • Locomotion

  • Driving

  • Sports

  • Industrial tasks

Data Analysis in Tobii Pro Lab:

When analysed in Tobii Pro Lab, the recorded data can be transformed into a wide variety of visualizations and quantitative metrics.

Researchers can generate:

  • Heat maps

  • Scan paths

  • Gaze plots

  • Fixation statistics

  • Areas of Interest (AOIs)

  • Time of Interest (TOI) analyses

  • Event coding

  • Participant comparisons

Data Export:

Tobii Pro Lab also enables researchers to:

  • Export raw data

  • Export processed data

This allows further statistical analysis using:

  • Third-party tools

  • Custom analysis pipelines

Summary:

Together, Tobii Pro Glasses 3 records synchronized eye tracking data, pupil measurements, first-person scene video, audio, and head movement data. When analysed in Tobii Pro Lab, these data streams can be visualized through heat maps, scan paths, gaze plots, fixation statistics, AOIs, TOI analyses, event coding, and participant comparisons, while also supporting the export of raw and processed data for further statistical analysis.
