Tobii Pro X2-30 eye tracker

Screen-based eye tracker capturing gaze data at 30 Hz. This compact, affordable system is perfect for studies outside of the lab. It is designed to give you instant insights into visual attention in high-level fixation-based research.


Fully-mobile for instant, cost-efficient insights

The Tobii Pro X2-30 snaps into place on your laptop, providing a compact, highly-mobile solution. The system enables you perform cost-efficient studies in a coffee shop, at the mall, or in an office – wherever your subjects are. Get instant insight into visual attention and interest.

The Pro X2-30 is designed to capture data at 30 Hz in order to show exactly where people are looking— the gaze point — rather than for research into the timing and duration of fixations. It offers an affordable solution, perfect for qualitative research, such as live-viewing studies.

Versatile for many types of qualitative studies

Present your stimuli on a variety of screens – laptops, PC monitors, tablets, or TVs. The Pro X2-30 can be mounted on screens up to 25" in size. We offer accessories in order to make research with mobile devices easier. The system's high-quality tracking of large gaze angles (up to 36°) allows you to also study large projections.

There are additional accessories to accommodate studies of real-world stimuli, such as physical objects or people.

Easy to use 

Simple setup, configuration, and automation promote efficient eye tracking studies.

  • Attaches easily with supplied mounting solutions for various screens
  • Connects directly into your PC (using a USB cable)
  • Simple configuration for Windows 7 and 8.1
  • Calibrates subjects quickly and automatically

"The Tobii Pro X2 is as small as a Nintendo Wii bar and plugs into a laptop to power itself. It means that, for the first time, you can conveniently study people in their own homes. This is perfect for website development and can alleviate many of the disadvantages of the current interviewing practice."

Steve Mellor, Qualitative Director, Tpoll

Captures natural behavior

Subjects can be tracked while moving their head freely positioned at a natural distance from the screen. This creates a distraction-free test environment, promoting natural human behavior.

  • Tolerates large and fast head movements
  • Collects highly-accurate data from close distances, such as a laptop, to longer distance, such as an ATM
  • Stable and reliable eye tracking calibrations eliminate the need for recalibration

Accurate and robust tracking

The system's exceptionally-high accuracy and vast tracking robustness in real-life conditions ensure high-quality data while allowing you to work with a wide cross-section of your population.

  • Delivers exceptionally accurate gaze-position data within the entire tracking box
  • Vastly-robust tracking capability regardless of ethnicity or corrective lenses with low data loss
  • Maintains accuracy and tracking robustness during subjects' head movement and in ambient light
  • Dual-camera system automatically selects bright or dark pupil eye tracking

“Just done a second session using the Tobii Pro X2, which was awesome. LOVE IT.”

Oliver Bradley, Global eCommerce Innovation & Strategy Director at Unilever
