What Is Tobii Pro Fusion?

A professional screen-based eye tracker for behavioral research in both lab and real-world settings is called Tobii Pro Fusion. It falls between the Tobii Pro Spark and Tobii Pro Spectrum in terms of portability and research-grade accuracy, which makes it appropriate for studies involving pupillometry, fixation analysis, saccades, smooth pursuit, developmental psychology, neuroscience, usability testing, clinical research, and human-computer interaction. Tobii Pro Fusion provides a great combination between performance, adaptability, and deployment simplicity with sampling rates of up to 250 Hz.

How Does Tobii Pro Fusion Work?

• The system uses video-based pupil and corneal reflection (PCCR) eye tracking with Tobii's patented 3D eye model.

• Two high-speed eye tracking cameras continuously capture stereo images of both eyes while infrared illuminators generate corneal reflections that allow the system to calculate gaze direction in three-dimensional space.

• Depending on the sampling frequency, the tracker automatically switches between:

  • Dark-pupil tracking mode

  • Bright-pupil tracking mode

  to provide optimal performance across different participants and lighting conditions.

Dual-Camera Architecture

• Unlike conventional screen-based eye trackers that require participants to remain almost perfectly still, Tobii Pro Fusion features a dual-camera architecture that offers excellent tolerance to natural head movement while maintaining high-quality gaze data.

• Fully embedded processing ensures that all eye tracking calculations occur within the device itself, minimizing latency and reducing the computational load on the host computer.

• Researchers simply:

  • Connect the tracker via USB

  • Perform a short calibration

  • Begin collecting gaze data within minutes

Flexible Deployment

Because of its portability, Tobii Pro Fusion can be mounted beneath:

• Laptop screens

• Desktop monitors up to 24 inches

It can also be:

• Installed on a tripod to study physical objects

• Installed on a tripod to study real-world stimuli

This flexibility enables researchers to perform experiments in:

• Laboratories

• Schools

• Clinics

• Hospitals

• Field environments

without sacrificing data quality.

Summary

In order to provide research-grade eye tracking with portability and flexibility across laboratory and real-world research environments, Tobii Pro Fusion is a professional screen-based eye tracker that combines video-based pupil and corneal reflection (PCCR) eye tracking, Tobii's patented 3D eye model, dual high-speed eye tracking cameras, automatic bright-pupil and dark-pupil tracking, fully embedded processing, and USB connectivity.
