3 Safety
3.1 General precautions
The Tobii Pro Glasses 3 system is described in the Tobii Pro Glasses 3 User Manual
and must be used according to the manufacturer’s instructions. Connecting any other
component to the system, or using the components improperly can cause injury to the
user or damage to the equipment and is done so entirely at the user’s own risk.
The glasses system must be fitted on the test participant according to instructions in
the Tobii Pro Glasses 3 User Manual. Tobii or its agents are not liable for damage or
injuries to a person or their property due to a Tobii Pro Glasses 3 eye tracker system in
any configuration being dropped. Fitting the glasses onto a test participant is done
entirely at the user’s own risk.
The glasses system is to be used for research purposes only. Be aware that due to the
low, but possible risk of failure or distraction, Tobii Pro Glasses 3 should not be relied
upon or used in dangerous or otherwise critical situations.
The Tobii Pro Glasses 3 system is composed of several components as described in
the User Manual and should be used according to manufacturer instructions. Con-
necting, or by other means using any other component than advised in the User
Manual may damage or injure a person, their property or recorded data, and is done
entirely at the user’s own risk.
The head unit is equipped with a head strap to enable tighter mounting of the eye
tracker onto the wearer’s head. Neither Tobii nor its agents are liable for damages or
injuries to a person or their property caused by the head unit head strap.
3.2 Emergency
The Tobii Pro Glasses 3 system is to be used for research purposes only. Be aware
that due to the low, but possible risk of failure or distraction, the Pro Glasses 3 should
not be relied upon or used in dangerous or otherwise critical situations.
3.3 Child warning
Tobii Pro Glasses 3 is an advanced system with electronic devices that are composed
of numerous separate, assembled parts. These parts can become separated from the
device, constituting a potential choking hazard or other danger to a child. Young chil-
dren should not have access to or use the device without parental or guardian super-
vision.

Tobii Pro Glasses 3 User Manual v 1.9 10
3.4 Infrared warning
Do not use the Tobii Pro Glasses 3 system when in the vicinity of devices that are sus-
ceptible to Infrared (IR) light. When activated, the head unit emits IR light, which can
affect certain medical devices and other devices that are susceptible to disturbance by
IR light and/or radiation.
3.5 Photosensitivity/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. These 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 the participant starts to feel odd during use, have them remove the head unit
immediately.
3.6 Mechanical shock
The Tobii Pro Glasses 3 system is a delicate measuring instrument used for research
purposes and should be treated with care at all times. To avoid breaking or damaging
the internal electronic circuits, do not drop, knock, or shake the device. Eye tracking
quality or accuracy can be seriously affected if the head unit or recording unit are
dropped. If the eye tracker is exposed to mechanical shock, for example, when
dropped, do not try to start it or connect it to a power source. Contact Tobii Customer
Care for instructions.
3.7 Bending
To avoid breaking or damaging the internal electronic circuits, do not bend any part of
the eye tracking system. Eye tracking quality or accuracy can be seriously affected if
the head unit or recording unit has been bent.
3.8 Do not open or disassemble
Do not open or disassemble the head unit or the recording unit. Noncompliance will
result in loss of warranty! There are no user-serviceable components inside. Contact
Tobii Customer Care if your Tobii Pro Glasses 3 system is not working properly.

Tobii Pro Glasses 3 User Manual v 1.9 11
3.9 Connectors
The head unit and recording unit have numerous external interfaces (connectors). Con-
necting any other device or connector than those intended may cause personal injur-
ies and/or damage the glasses system. Tobii or its agents are not liable for any
damages or injuries to a person or their property due to connecting unintended con-
nectors.
3.10 Head unit cable
The head unit cable connected to the head unit must only be used to connect to the
recording unit. Do not use the head unit cable for any other purpose or for connecting
to any other devices. Tobii or its agents are not liable for any damages or injuries to a
person or property due to incorrect use of the head unit cable.
3.11 Environment
Avoid any exposure to direct sunlight as this will affect eye tracking quality and longer
exposure can overheat the equipment. Avoid prolonged exposure to any liquids, gels,
moist, rain, or sweat. Do not use the eye tracker underwater.
Do not place or use the equipment in places subject to extreme temperatures and
humidity, such as on top of and or near a heating element, in a hot or damp room, or in
a hot automobile in the sun. Usage temperature: 5℃to +45℃ / 23℉ to 113℉
3.12 Component connection safety
The head unit is designed to connect only to the Tobii Pro Glasses 3 recording unit and
should not be connected to any other device.
The recording unit is designed to connect to the head unit, a device running specific
operating systems, with the Tobii Pro Glasses 3 controller application installed. The
recording unit should not be connected to any other devices.
3.13 Battery safety
There is a risk of explosion if the battery is replaced by an incorrect type.
Replacement of a battery with an incorrect type can defeat safeguards (for example, in
the case of some lithium battery types).
Disposal of a battery in a fire or a hot oven, or mechanically crushing or cutting of a bat-
tery can result in an explosion.

Tobii Pro Glasses 3 User Manual v 1.9 12
Batteries exposed to extremely high temperatures or environments can result in an
explosion or leakage of flammable liquid or gas.
Batteries subjected to extremely low air pressure may result in an explosion or the leak-
age of flammable liquid or gas.
Attention!
Risque d'explosion en cas de remplacement de la pile par une pile de type incorrect.
Le remplacement d'une PILE par une pile de type incorrect peut neutraliser un
SYSTÈME DE SÉCURITÉ (par exemple dans le cas de certains types de PILES au
lithium).
La mise au rebut d'une PILE dans le feu ou dans un four chaud, ou par écrasement ou
découpe, peut entraîner une EXPLOSION.
L'exposition d'une PILE à un environnement présentant une température extrêm-
ement élevée peut entraîner une EXPLOSION ou une fuite de liquide ou de gaz inflam-
mable.
L'exposition d'une PILE à une pression d'air extrêmement faible peut entraîner une
EXPLOSION ou une fuite de liquide ou de gaz inflammable.
3.14 Wireless warning
The recording unit contains radio transmitters and receivers (WLAN). Make sure that it
is placed as far as possible from any equipment, objects or body parts sensitive to
such signals.
電波法により5GHz帯は屋内使用に限ります。
3.15 Transportation

ginal packing.
For transportation, the recommended range for temperature and humidity for the device is as fol-
lows:

3.17 Cleaning
Avoid touching, scratching, or smudging the lenses on the head unit and/or the Cor-
rective Lenses (optional accessory) and keep all the surfaces clean. Eye tracking qual-
ity may be degraded if surfaces are dusty or damaged. Take special care to ensure
that there are not smudges or scratches covering either the illuminators or sensors in
the lenses as these can impair performance.
Do not use window cleaners, household cleaners, aerosol sprays, solvents, alcohol,
ammonia, or abrasives on any component of the Tobii Pro Glasses 3 system.
Before cleaning the glasses, unplug the head unit cable.
Use the included cleaning cloth and clean the glass lenses gently.
