1.4 How Tobii Pro Nano works
During eye tracking, Tobii Pro Nano uses infrared illuminators to generate reflection patterns on
the corneas of the participant’s eyes. These reflection patterns, together with other visual data
about the participant, are collected by image sensors. Sophisticated image processing algorithms
identify relevant features, including the eyes and the corneal reflection patterns. The Tobii Pro
Nano is a single camera system that uses a combination of dark and bright pupil tracking. Com-
plex mathematics is used to calculate the 3D position of each eyeball, and finally the gaze point;
in other words, where the participant is looking.
1.5 Tobii Pro Eye Tracker Manager
Tobii Pro Eye Tracker Manager is free software available on Tobii Connect.
Tobii Pro Eye Tracker Manager helps you manage your Tobii Pro eye tracker. It lets you see

2 Safety
2.1 Mounting warning
Tobii Pro eye trackers should be mounted according to the instructions of the
approved mounts used.
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.
2.2 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.
2.3 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.
2.4 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).

Tobii Pro Nano User Manual v2.3 9
2.5 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.
2.6 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.
2.7 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 Customer Care if your eye
tracker is not working properly.
2.8 Accessories
Only use accessories provided by or approved by Tobii AB.
2.9 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 AB
can not take any responsibility in these situations.

6. Proceed to the next step.
5.3 Mount the eye tracker on a laptop or monitor
To ensure quality in eye tracking data, your eye tracker hardware package includes several
mounting plates that can be affixed to a laptop or monitor. You can easily snap the eye tracker on
and off the screen bezel using the magnetic mounting plate. The mounting plate sticks to the
frame with a special adhesive that doesn’t damage the underlying surface when the mounting
plate is removed. For more information, read Detach the eye tracker.
What to do:
1. Check that your eye tracker is detected and displayed as a “card” in Tobii Pro Eye Tracker
Manager. Expand your eye tracker’s “card” in Tobii Pro Eye Tracker Manager to see that
the serial number of your eye tracker matches the number displayed.
2. You can leave your eye tracker USB connected and beside your computer or you can dis-
connect it while attaching the mounting hardware.
3. Find the center of the screen and clean the bezel.
Important! If you plan to attach the eye tracker to a laptop, make sure the laptop
can close with the magnetic mounting plate attached. Some laptops have very
little space when closed and this could damage the screen.
4. Peel the adhesive tape off the mounting plate and mount it on the bezel. Press the bracket
against the bezel for 30 seconds and leave it there for one hour before attaching the eye
tracker.
Figure 1. Align the mounting bracket properly. The magnet holds the eye

You can always return to Tobii Pro Eye Tracker Manager and use it when you change
computers or screens or when you wish to redo a setup.

Tobii Pro Nano User Manual v2.3 15
5.5 Calibration
When you are done configuring your eye tracker, you should run a calibration to test if the eye
tracker is mapping the gaze points correctly to your display.
How to test your eye tracking setup:
1. Make sure the eye tracker is attached to the monitor and connected to your computer.
Open Tobii Pro Eye Tracker Manager. For more information, read Tobii Pro Eye Tracker
Manager .
2. By now, you should have also tested your setup as described in Display setup in Tobii Pro
Eye Tracker Manager.
3. Select the Calibrate button in Tobii Pro Eye Tracker Manager and follow the on-screen
instructions.
4. Evaluate your calibration results.
Large systematic errors i.e. a large distance between the average gaze point and the tar-
get gaze point may be indicative of a configuration error. No calibration feedback data on
the targets located on the top of the screen may indicate that there is a mismatch between
the screen size and eye tracker configuration. Select the Recalibrate button to improve a
calibration. Select the Use Calibration button when you are satisfied with the your cal-
ibration.
5.5.1 What calibration does
The human eye shows a natural individual variation in its shape and geometry. For example, the
exact location of the fovea, the area responsible for the part of the visual field that we perceive in
focus and full color, varies from individual to individual. Tobii Pro Eye Trackers use an individual
calibration procedure to optimize their gaze estimation algorithms (i.e. the 3D eye model) and
account for this variation. The end result of this optimization is a fully-customized and more accur-
ate gaze point calculation.
You can do basic calibration in Tobii Pro Eye Tracker Manager. There is more functionality, includ-
ing calibration validation, in Tobii Pro Lab.
You can find more information on Tobii Connect about calibration and performing a calibration
and validation in Tobii Pro Lab.
5.5.2 Additional information for experienced users
A participant can be calibrated with Tobii Pro Nano even when only one eye was suc-
cessfully calibrated. That calibration gets copied to the “failed” eye as well, and this
might cause poor data for that eye.
Tobii Pro Nano produces only one vector for the calibration results, thereby providing
information on the average estimated accuracy, but not on the estimated precision.
Use the Left and Right eyes results in Tobii Pro Eye Tracker Manager and/or Tobii Pro
Lab to determine whether both eyes were calibrated successfully. You can also
choose to analyze the data only for the eye that successfully calibrated.

Tobii Pro Nano User Manual v2.3 16
5.6 Detach the eye tracker
To temporarily remove the eye tracker, pull it away from the magnetic mounting plate and leave
the magnetic plate in place.
To permanently remove the magnetic mounting plate, you must remove the non-permanent but
strong adhesive that fastens your eye tracker mounting plate to the screen bezel. Since it is fairly
strong, you may not be able to take it away with only your fingers. If you want to remove it, we
recommend using something very thin such as dental floss or a thin thread, a guitar pick, or a
credit card. Use this to slide between the mounting plate and the computer bezel (or whatever it is
attached to). As you slide it behind the mounting plate, gently bend the mounting plate backwards
so that it detaches.

Tobii Pro Nano User Manual v2.3 17
6 Display Setups
6.1 Standard setup
The standard setup for using the Tobii Pro Nano is with a screen up to 24" *. The eye tracker is
attached below the screen whether it is a laptop screen or separate monitor.
* For larger screens, the limiting parameter is the quality of the gaze accuracy at the upper
corners of the screen when the user sits close to the screen.
6.2 Tips for setting up the eye tracker display
If the screen bezel is thinner than the width of the eye tracker, affix the mounting plate as low as
possible on the screen frame, or directly on the screen.
lDon’t use this setup if you intend to put stimuli in the lower part of the screen, as the eye
tracker might cover them.
lWe recommend that you remove the mounting plate before closing the lid of the laptop.
lUse Tobii Pro Eye Tracker Manager’s Display Setup — Advanced function to select a neg-
ative value for the height distance between the top of the eye tracker and the bottom of the
display screen. Alternatively, use the tripod accessory and mount the eye tracker away
from the screen.
6.3 Set up with a tripod
Figure 3. Set up with a tripod

Tobii Pro Nano User Manual v2.3 18
If you want to use a wider screen, the hardware is set up in a slightly different manner:
1. Select a suitable location and set up the screen.
2. Set up the projector and connect it to the laptop.
3. Mount the eye tracker on a separate tripod and connect it to the laptop.
4. Use Tobii Pro Eye Tracker Manager’s Advanced Setup to ensure that the eye tracker can
detect the participant’s eyes. Select New in the drop-down Display Setup menu and follow
the steps.
5. Give your screen configuration a name so that you can reuse the settings later. Type it in
the Display Setup Name text box, then click the Save button. Your configuration is now
available and selected in the Display setup drop-down menu.
6. Test the screen configuration by performing a calibration. If you are tracking a physical
plane instead of a screen, the calibration must be done in Tobii Pro Lab.
For more detailed instructions, read the Tobii Learn article Using Pro Eye Tracker Manager to con-
figure the eye tracker.
You must measure and specify all the parameters as accurately as possible to main-
tain good eye tracking data quality.
