Some research questions are better studied closer to where people learn, work, or receive care. Tobii Pro Fusion brings up to 250 Hz gaze measurement and robust dual-camera tracking into a portable screen-based setup that can move between labs, classrooms, clinics, and other research locations.

Research across locations
At just 168 g with USB-C connectivity, Tobii Pro Fusion makes it easy to take research-grade eye tracking wherever your study takes you.
Go beyond fixation data
Capture gaze up to 250 Hz alongside pupil diameter and eye openness — supporting fixation, saccade, cognitive, pupillometry, and multimodal research.
Reaching vulnerable populations
Support research with children, older adults, and clinical populations who may find traditional lab-based studies difficult to access.
Tobii Pro Fusion's two synchronized cameras and patented 3D eye model deliver the same data quality in a field setup as you'd expect from a fixed lab system — across the full range of participants and lighting conditions.
Robust for diverse participants
Reliable binocular tracking across diverse participants, including children, older adults, and people who wear corrective lenses.
Natural head movement
Dual-camera stereo imaging maintains tracking through natural head movement at 65cm distance, no chin rest needed, even for participants who can't sit still.
Optimized for field lighting
Bright and dark pupil illumination modes deliver consistent data whether you're in a controlled lab, a classroom with fluorescent lighting, or a living room.
Lightweight and portable
The entire eye tracker weighs less than a smartphone. Carry it between sites, set it up in minutes, and run the same protocol you'd use in your lab.
Researchers at Yale, Cambridge, the University of Tokyo, and hundreds of other institutions use Tobii Pro Fusion for controlled lab studies and research beyond the lab — from reading research in classrooms to clinical and behavioral research with diverse participant groups.
Tobii Pro Fusion performance is documented through public laboratory and field data-quality reports, including field testing with 500+ participants, while peer-reviewed studies demonstrate its use across varied participants, research questions, and study locations.

Patented 3D eye model
Supports high-quality gaze, pupil-diameter, and eye-openness signals from Tobii’s model-based eye tracking.
Dual cameras
Two Tobii EyeSensor modules capture stereo images of both eyes at up to 250 images per second for robust binocular tracking.
On-device processing
Three Tobii EyeChip™ ASICs handle all gaze computation on the tracker itself, no external processing box.
Single USB cable setup
Connect via USB-C (or USB-A with included adapter). Powers directly from your laptop, no external power supply needed in the field.
Flexible setup
Windows, macOS, and Linux; compatible displays up to 24 inches, or tripod setups for larger screens and physical stimuli.
Design experiments, record gaze and ocular data, inspect recordings, analyze fixations and AOIs, and visualize results with heat maps and gaze plots — all in one guided workflow. Export processed metrics or raw data for further analysis.

Our study participants are people with Autism Spectrum disorders or Schizophrenia where having an eye tracking system that is unobtrusive and allows for head movement is imperative. The dual eye tracking cameras, sampling rate and discreet design with Tobii Pro Fusion will open up the possibilities for more extensive research on our demographic.

We have had a great experience using Tobii Pro Fusion and Tobii Pro Lab. It is easy to extract the numerical results from the Tobii Pro Lab software. We have even created a custom software program to upload the Tobii Pro Lab databases and calculate the optometric parameters needed in every optometric test we performed.
