If you have a busy lab with students running different projects, it’s likely that each project will have different demands on the eye tracking setup. Tobii Pro Fusion provides a flexible solution that supports different research scenarios and study designs. The slim design integrates well with different stand-alone and laptop screens up to 24 inches in size. The eye tracker can also be mounted on tripods and coupled with a scene camera so it can be used in study setups that use real-world stimuli such as physical objects or scenes.
Tobii Pro Fusion
Reach further with your research
A screen-based eye tracker, capturing gaze data at speeds up to 250 Hz. This powerful research system supports from fixation to saccade-based research outside of the lab.
Overview
Overcome research barriers
With sampling frequencies of up to 250 Hz, two eye tracking cameras, and two pupil tracking modes, Tobii Pro Fusion enables you to adapt and extend your data collection setup to different research populations, scenarios, and data requirements.
Collect your data where your subjects are available
The size and shape of Tobii Pro Fusion allow for a compact mobile lab without compromising on data quality and granularity. The patented Tobii eye tracking algorithms and robust subject calibration ensures reliable data across different indoor environments, making it easier to recruit participants.
Support for different data collection scenarios
The sampling speed of up to 250 Hz allows you to capture data for a wide range of experimental paradigms (fixation, smooth pursuit, and saccade based). The different sampling frequencies and associated bright and dark pupil tracking modes allow you to adapt the performance to your study design and test population.*
*The illumination mode is selected automatically by the system during calibration.

Effects of paradigm color and screen brightness on visual fatigue in light environment of night based on eye tracker and EEG acquisition equipment
Tian and colleagues (2022) studied the impact on human visual fatigue of electronic-device use in a dark environment at night. Tobii Pro Fusion was used to measure pupil dilation, and G.tec EEG to measure brain activity while participants performed tasks in a dark environment with different screen brightness levels and colors.
The role of eye tracker in teaching video-assisted thoracoscopic surgery: the differences in visual strategies between novice and expert surgeons in thoracoscopic surgery
Ji and colleagues (2022) used Tobii Pro Fusion to study the differences in fixation patterns and search strategies between novices and expert surgeons while watching an instructional video of surgery. To assess learning efficiency, some novices watched the instructional video a second time, but overlaid with eye-movement data of senior surgeons.
Impaired empathic accuracy following damage to the left hemisphere
Jospe and colleagues (2022) further investigated why strokes can lead to a decline in emotional understanding. They assessed patients with chronic damage in the left and right hemispheres. The researchers used an empathic accuracy naturalistic task together with eye tracking methods with Tobii Pro Fusion to explore patient understanding of the effect of others.
