Overview

Small but powerful

This is our smallest eye tracker with advanced streams and a sampling rate of 60Hz. Supported by Tobii Pro Lab and Tobii Pro SDK, it has the power to capture high-quality attention data. With Tobii Academy, Tobii Connect, and our customer care, you have a completely supported research solution.

Tobii Pro Spark

Portable and easy to use

The manageable size and carrying case make it easy to pack up and go. Tobii Pro Spark has fully embedded processing and is easy to connect via USB or USB-C, with no additional power supply required. This single-camera eye tracker functions on screens up to 27” and is compatible with all platforms, including Windows, Mac, and Linux.

Tobii Pro Spark

Our most affordable solution

Whether you're applying for limited research funds or taking your first steps in eye tracking research, affordability is paramount. Tobii Pro Spark puts eye tracking within reach for countless researchers looking to enhance their research.

Tobii Pro Spark

Robustness and quality

No matter which eye tracker you choose, accuracy and reliability are our number one priority. Tobii Pro Spark is no exception, offering robust tracking capabilities regardless of corrective lenses or ethnicity. We also guarantee high tolerance of head movement under various lighting conditions, and tracking is resumed quickly if the participant looks away.

Tobii Pro Spark

Who is it for?

We wanted to create an eye tracker that serves scientific researchers, that is also accessible for commercial research. Both fields deserve accuracy, flexibility, and powerful insights, which is why we designed a portable, powerful, and versatile addition to our portfolio.

Scientific research

Tobii Pro Spark is perfect for scientific researchers who want to understand visual attention on a deeper level. Task completion and decision-making can be better understood and explored through attention data, which provides fresh perspectives and insights into education research, psychology research, teaching, engineering, technology design, and more.

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.

Features

Technology to spark your research

Tobii Pro Spark offers robust and reliable data at an affordable price, making powerful eye tracking technology available to more people.

  • Sampling rate of 60 Hz designed for fixation-based research

  • Offers fully embedded processing of eye tracking data

  • Connects via a USB port directly to your computer

  • Works regardless of corrective lenses

  • Demonstrates robust tracking regardless of ethnicity or age

  • Tolerance for head movements and varied lighting conditions
