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)

4 Safety
4.1 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
monitors or laptop screens. It is also designed for clean removability. Failure to follow
the recommended removal instructions can result in damage to both the mon-
itor/laptop and the mounting bracket. Do not mount the eye tracker on monitors posi-
tioned above the head or face of a user, as it might fall.
4.2 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.
4.3 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 pho-
tosensitive epilepsy experience an “aura” or feel odd sensations before the seizure
occurs. If you feel odd during use, move your eyes away from the eye tracker.
4.4 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 accur-
acy or proper functionality could be inhibited. Do not stare into the LED lights at a close
distance (<15cm).
Pro Fusion Product Description v2.3 16
4.5 Magnetic field warning
This Tobii Pro eye tracker contains magnets. Magnetic fields may interfere with the
function of cardiac pacemakers and implantable cardioverter defibrillators. As a gen-
eral rule, maintain a minimum distance of 6 inches (15 centimeters) between any item
with magnets and your heart device.
4.6 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.
4.7 Electricity
Do not open the casing of the Tobii Pro eye tracker, this could expose you to poten-
tially 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.
4.8 Accessories
Only use accessories provided by or approved by Tobii Pro AB.
4.9 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.
4.10 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
Service 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.

Appendix B Limitations and considerations
B1 Intended use
Tobii Pro eye trackers are intended to be used in research activities about human
behavior including eye movements, in a dry and dust free indoor environment. The
product should only be used as described in this User’s Manual. Please read the User
Manual and other supplied documentation thoroughly before using the product.
B2 Light conditions
Tobii Pro recommends that eye tracking studies be performed in a controlled envir-
onment. Sunlight should be avoided since it contains high levels of infrared light which
will interfere with the eye tracker system. Sunlight affects eye tracking performance
severely and longer exposure can overheat the eye tracker. This eye tracker is not
designed for exposure to (direct) sunlight. Eye tracking generally does not work in
strong direct sunlight.
Shielding the eye tracker adequately from the sun may prevent sunlight from inter-
fering with eye tracking.
B3 Eyelashes
Long eyelashes can be obstructive when the participant’s eyes are less open, espe-
cially if the participant is wearing mascara. In rare cases, eyelashes may completely
block the view of the participant’s pupils, making eye tracking impossible.
B4 Droopy eyelids
Droopy eyelids or otherwise obstructive eyelids can block the view of the participant’s
pupils. In rare cases, such eyelids may completely block the view of the participant’s
pupils, making eye tracking impossible.
