1 Introduction
Tobii Pro Fusion is a compact, high performance data collection solution that you can take into the
field. Use Pro Fusion when your research takes you to locations and to subjects that would oth-
erwise be hard to bring to the lab. You can collect data in schools, hospitals, libraries, and other loc-
ations where your subjects are easier to recruit.
With sampling frequencies of 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 data requirements.
Use Pro Fusion for studies on:
lWindows laptop and desktop computers
lPC monitors, 24″ (16:9) or less as optimum size
lReal-world setups such as physical objects and social interactions (using the Tripod Stand)
lProjections, simulators, and larger screens (using the Tripod Stand)
Tobii Pro Fusion is primarily designed for use in indoor office environments with adult participants.

3 Safety
3.1 Mounting warning
Tobii Pro eye trackers should be mounted according to Tobii Pro´s instructions for
approved mounts.
The mounting bracket is designed for adhesion to a wide variety of surfaces, such as mon-
itors or laptop screens. It is also designed for clean removability. Failure to follow the
recommended removal instructions can result in damage to both the monitor/laptop and
the mounting bracket. Do not mount the eye tracker on monitors positioned above the
head or face of a user, as it might fall.
3.2 Emergency warning
Tobii Pro eye trackers are designed to be used only for research purposes. Be aware
that due to the low, but possible risk of failure or distraction, the eye tracker should not be
relied upon or used in dangerous or critical situations.
3.3 Epilepsy warning
Some people with photosensitive epilepsy are susceptible to epileptic seizures or loss of
consciousness when exposed to certain flashing lights or light patterns in everyday life.
This may happen even if the person has no medical history of epilepsy or has never had
any epileptic seizures.
A person with photosensitive epilepsy would also be likely to have problems with TV
screens, some arcade games, and flickering fluorescent bulbs. Such people may have a
seizure while watching certain images or patterns on a monitor, or even when exposed to
the light sources of an eye tracker. It is estimated that about 3-5% of people with epilepsy
have this type of photosensitive epilepsy. Many people with photosensitive epilepsy
experience an “aura” or feel odd sensations before the seizure occurs. If you feel odd dur-
ing use, move your eyes away from the eye tracker.
3.4 Infrared warning
When activated, the Tobii Pro eye tracker emits pulsed infrared (IR) light. Certain med-
ical devices are susceptible to disturbance by IR light and/or radiation. Do not use the eye
tracker in the vicinity of these kinds of susceptible medical devices, as their accuracy or
proper functionality could be inhibited. Do not stare into the LED lights at a close distance
(<15cm).

Pro Fusion User Manual v.2.2 9
3.5 Magnetic field warning
This Tobii Pro eye tracker contains magnets. Magnetic fields may interfere with the func-
tion of cardiac pacemakers and implantable cardioverter defibrillators. As a general rule,
maintain a minimum distance of 6 inches (15 centimeters) between any item with mag-
nets and your heart device.
3.6 Child safety
A Tobii Pro eye tracker is an advanced computer system and electronic device. As such,
it is composed of numerous separate, assembled parts. In the hands of a child, some of
these parts have the possibility of being separated from the device, possibly resulting in a
choking hazard or other danger to the child.
Young children should not have access to, nor use of the device or its accessories
without parental or guardian supervision.
3.7 Electricity
Do not open the casing of the Tobii Pro eye tracker, this could expose you to potentially
hazardous electrical voltage. The device contains no user-serviceable parts. Non-
compliance will result in loss of warranty! Contact Tobii Pro Support if your eye tracker is
not working properly.
3.8 Accessories
Only use accessories provided by or approved by Tobii Pro AB.
3.9 Third party
Any use of a Tobii Pro eye tracker outside the intended use and together with any third-
party software or hardware that changes the intended use is a risk, and Tobii Pro AB can
not take any responsibility in these situations.
3.10 Power supply
Only use the AC power adapter provided by Tobii Pro to power your Tobii Pro eye
tracker. If the AC power adapter is damaged, it should be replaced only by Tobii Pro Ser-
vice Personnel. If damaged, do not use the AC power adapter until it has been replaced.
Tobii Pro and its agents are not liable for any damages or injuries to a person or property
due to incorrect use of the provided accessories.

4 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 camera 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)
4.1 Product versions
