How does it work

How to does Tobii Pro Spark work?

Tobii Pro Spark


Tobii Pro Spark is designed for quick and easy setup! Attach to any screen up to 27”, or place it on a tripod for studies of real-world stimuli. Simply connect to the computer via USB.

Tobii Pro Spark


Start recording high-quality attention data. Robust tracking means minimal data loss and reliable results regardless of corrective lenses, age, or ethnicity.

Tobii Pro Spark


Tobii Pro Spark works with
Tobii Pro Lab, supporting researchers from experiment design to data analysis. Eye tracking metrics and visualizations help you understand participants’ visual attention and behavior on a deeper level.

Fields of use

Built for all research

We wanted to make an eye tracker that delivers for scientific researchers, but that’s also accessible for commercial research.

Tobii Pro Spark

Scientific research

Tobii Pro Spark is perfect for scientific researchers who want to understand visual attention and behavior on a deeper level. Attention data illuminates problem-solving and decision-making processes bringing unique perspectives and insights into education, computer science, psychology research, and more.

Tobii Pro Spark use for Consumer research

Commercial research

Consumer insights are the name of the game in marketing research. Most companies know what their customers are doing, but eye tracking allows you to cut deeper into the why. Whether you’re testing the impact of your packaging or your advertisements, attention data can illuminate your customer in new ways.

About the tech

  • Captures gaze and pupil data

  • Our patented 3D eye model delivers high-quality gaze data

  • One eye tracking camera, taking up to 60 images per second

  • Bright and dark pupil illumination modes automatically selected for best performance

  • Fully embedded processing

  • Easy USB or USB-C connectivity

  • Simple screen attachment

  • Compatible with all main operating systems

  • Accurate software synchronization options with a wide range of external devices, such as EEG, ECG or GSR


Data you can trust

  • Works across the population regardless of age, ethnicity, or corrective lenses

  • Maintains tracking robustness in different lighting environments

  • Keeps high performance through natural head movements

  • Small and portable for easy transportation

  • Tobii Pro Spark provides precise tracking results that are robust against variations in illumination and head movements. It is an excellent solution to study learning and problem-solving strategies and to evaluate instructional materials even in group settings.

    Dr. Stefan Küchemann

    Group Leader AI in Physics Education, Faculty of Physics, Chair of Physics Education, LMU Munich

  • We investigate individual differences in large and diverse samples, such as the thousands of museum visitors who have enjoyed our public eye tracking booth so far. Challenging settings like this require everything we found in Tobii Pro Spark — extremely robust and user-friendly eye tracking at a spatial accuracy that rivals any other research device.

Technical specifications

For definitions of the terms used in the tables below, see the Glossary on Tobii Connect.

For more information about output data and the supplementary data stream, please read the Tobii Pro SDK documentation.

The characteristics of the gaze data from an eye tracker are described in terms of accuracy and precision. For more details, take the Accuracy and precision course in Tobii Academy.

Eye tracking technique

Video-based pupil and corneal reflection eye tracking with dark and bright pupil illumination modes.

One camera captures images of both eyes for accurate measurement of eye gaze and eye position in 3D space, as well as pupil diameter.

Freedom of head movement (width x height)

Freedom of head movement at 50 cm distance 20 cm x 20 cm (7.9’’ x 7.9’’) (At least one eye tracked) 

Freedom of head movement at 65 to 80 cm distance  35 cm x 35 cm (13.8’’ x 13.8’’) (At least one eye tracked) 

Optimal screen size

Up to 27" (16:9 aspect ratio)

Recommended monitor


Tracker setup options

Eye tracker mounted on a tripod, allows for even larger screens or physical objects to be tracked.

The Mobile Testing Accessory enables research or usability tests on a mobile device.
