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

Capture

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

Understand

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.

Features

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

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.
