1 Overview of Tobii Pro Fusion
Tobii Pro Fusion is the next generation of compact high-performance eye trackers from Tobii
Pro. It provides a flexible solution that supports different research scenarios and study designs.
Pro Fusion has a slim design that integrates well with external monitors up to 24 inches and
laptop screens. The eye tracker can also be mounted on a tripod and coupled with a scene cam-
era so it can be used in study setups that use real-world stimuli such as physical objects or
scenes. 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).
With high, selectable, sampling rates (up to 250 Hz), two eye tracking cameras and two pupil
tracking modes (bright and dark pupil), Pro Fusion enables you to adapt your data collection
setup to different research populations, scenarios, and date requirements.
Use Pro Fusion for studies on:
lWindows laptop and desktop computers
lPC monitors, 24″ (16:9) or less
lReal-world setups such as physical objects and social interactions (using the Tripod
Stand)
lLarger screens, projections, simulators (using the Tripod Stand)

Pro Lab
tobiipro.com/product-listing/tobii-pro-
lab/
Pro Lab is a comprehensive research software plat-
form for eye tracking designed to meet the highest
demands on different research scenarios with exact
timing accuracy. This software offers an efficient work-
flow, making it easy to design experiments, record
data, analyze and visualize eye tracking data, and to
sync this data with other biometric data streams.
Pro SDK
tobiipro.com/product-listing/tobii-pro-
sdk/
Pro SDK offers a broad set of tools that makes it
simple to develop a variety of niche applications or
scripts across multiple platforms, using a wide range
of programming languages. This SDK gives the
researcher access to the full set of relevant gaze data
streams, such as 3D eye coordinates, raw data, pupil
data, etc.
Third-party software This term refers to any application built on Pro SDK.

version
Precision** 0.04° RMS at optimal conditions***
0.2° RMS in optimal conditions (raw signal)
Accuracy** 0.3° in optimal conditions
Binocular eye tracking Yes
Total system latency 3 frames (<12 ms at 250 Hz)
Blink recovery time 1 frame (immediate)
Gaze recovery time 250 ms
Data sample output**** Timestamp
Gaze origin

Eye image data stream Eye image data stream frequency is approximately 4 Hz (one
image per eye). Zoomed-in eye images available in tracking
mode. Full-frame camera images are available in gaze recov-
ery mode.
TTL input stream Not Available
Tracker and client time syn-
chronization
Integrated between the eye tracker time domain and the client
computer time domain
* Dark pupil tracking is supported in all sample frequencies. Bright pupil tracking mode is sup-
ported at 60 and 120 Hz.
** Tobii Pro uses an extensive test method to measure and report performance and quality of
data. Please download the Tobii Pro Fusion Eye Tracker Data Quality Test Report for more
