Tobii Pro Spark

Enter the world of eye tracking

Spark your research with our smallest and most affordable eye tracker. By capturing high-quality fixation data at 60hz, our entry-level eye tracker illuminates attention and intent.

Boost your insights

Tobii Pro Spark puts eye tracking within reach for even more researchers looking to enhance their behavioral studies. It samples eye tracking data at 60hz, it’s easy to set up and use, and can be trusted to deliver robust and reliable data across the population.

How does it work

How to does Tobii Pro Spark work?

Connect

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.

Capture

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

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.

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.

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.
