21 Introduction Tobii PCEye Go User’s manual .2.1.1 - en-US

2 Safety
The Tobii PCEye Go has been tested and appro ed as compliant to all the Specifications and Standards listed in the Appendix
B Compliance Information, page 42
in this manual and in the Appendix D Technical Specifications, page 44 – including, but not
limited to, the Medical De ice Directi e (MDD) 93/42/EEC.Ne ertheless, in order to ensure safe operation of your
Tobii PCEye Go de ice, there are a few safety warnings to bear in mind:
2.1 Mounting arning
The Tobii PCEye Go should be mounted according to MANUFACTURER instructions of appro ed mounts.
Tobii Technology or its agents are not liable for damage or injuries to a person or its property due to a Tobii PCEye Go
falling from a mounted configuration. The mounting of a Tobii PCEye Go is done entirely at the user’s own risk.
The double sided tape supplied with the adhesi e Magnetic Mounting Plates is designed to permanently attach the
bracket to the monitor/laptop. Attempting to remo e the bracket after attaching it using the supplied tape can result in
damage both to the monitor/laptop and the bracket.
Do not lick the tape or place any part of the tape or Magnetic Mounting Plate in one's mouth.
Do not mount the Tobii PCEye Go on monitors positioned abo e the head or face of a users unless using a dedicated
"fixed mounting" solution.
2.2 Emergency arning
Be aware that due to the low, but possible, risk of failure, the Tobii PCEye Go should not be relied upon exclusi ely as
an audio communications, or an en ironmental control, de ice in emergencies, as well as in dangerous, or otherwise
important, situations. Do not rely on the de ice for emergency calls or banking transactions. We recommend ha ing
multiple ways to communicate in emergency situations. Banking transactions should only be carried out with a system
recommended by, and appro ed according to the standards of, your bank.
2.3 Infrared arning
When acti ated, the Tobii PCEye Go emits pulsed infrared (IR) light. Certain medical de ices are susceptible to dis-
turbance by IR light and/or radiation. Do not use the Tobii PCEye Go when in the icinity of such susceptible medical
de ices as their accuracy or proper functionality could be inhibited.
2.4 Epilepsy arning
Some people with PPhhoottoosseennssiittii ee EEppiilleeppssyy are susceptible to epileptic seizures or loss of consciousness when ex-
posed to certain flashing lights or light patterns in e eryday life. This may happen e en if the person has no medical his-
tory of epilepsy or has ne er had any epileptic seizures.
A person with Photosensiti e Epilepsy would also be likely to ha e problems with TV screens, some arcade games,
and flickering fluorescent bulbs. Such people may ha e a seizure while watching certain images or patterns on a moni-
tor, or e en when exposed to the light sources of an eye tracker. It is estimated that about 3-5% of people with epi-
lepsy ha e this type of Photosensiti e Epilepsy. Many people with Photosensiti e Epilepsy experience an "aura" or feel
odd sensations before the seizure occurs. If you feel odd during use, mo e your eyes away from the eye tracker.
2.5 Magnetic Field arning
The Tobii PCEye Go Magnetic Mounting Plates contains magnets. Magnetic fields may interfere with the function of
cardiac pacemakers and implantable cardio erter-defibrillators. As a general rule, maintain a minimum distance of 6 in-
ches (15 centimeters) between any item with magnets and your heart de ice.
The magnets can also shut off the monitor on a laptop if the laptop is equipped with a magnetic sensor to switch off
the monitor when closing the laptop. If this happens, shut of the sensor on the laptop.
Tobii PCEye GoUser’s manual .2.1.1 - en-US 2 Safety 3

2.6 Child Safety
The Tobii PCEye Go is an ad anced computer system and electronic de ice. As such it is composed of numerous
separate, assembled parts. In the hands of a child certain of these parts ha e the possibility of being separated from
the de ice, possibly constituting a choking hazard or another danger to the child.
Young children should not ha e access to, or the use of, the de ice without parental or guardian super ision.
2.7 Do not Open the Tobii PCEye Go
Non-compliance will result in loss of Warranty! There are no user ser iceable components inside. Contact
Tobii Support if your Tobii PCEye Go is not working properly.
2.8 Gaze Interaction
Some people may experience a certain amount of fatigue (due to intentional eye focusing and hard concentration) or
e en a dryness of the eyes (due to less frequent blinking) when first getting used to Gaze Interaction. If you are experi-
encing fatigue or dry eyes start off slowly and limit the length of your Gaze Interaction sessions to your comfort le el.
Remoisturizing eye drops can be helpful to combat dryness.

4.1 Positioning
X cm / inches
FFiigguurree 44..11 Positioning
The mounted Tobii PCEye Go attached to its Magnetic Mounting Plates and to your de ice is designed to work optimally when it
is parallel to the user’s eyes at a distance from about 45 —90 cm (18 to 35 inches) for Tobii PCEye Go, see
Figure 4.1 Position-
ing, page 9
or Figure 4.2 Positioning when Users Leaning Sideways or Those Lying Down, page 9 .
X cm / inches
FFiigguurree 44..22 Positioning hen Users Leaning Side ays or Those Lying Do n
This means that for those users leaning sideways or those lying down the Tobii PCEye Go with monitor and computer de ice al-
so needs to be tilted in order to keep the users eyes parallel to the screen and at the optimal distance, see
Figure 4.2 Positioning
when Users Leaning Sideways or Those Lying Down, page 9
.
Make sure the user is placed comfortably in relation to the optimal positioning of, and distance from, the unit. Be aware
also that the user’s comfort, as well as the Gaze Interaction performance, will be enhanced if the sun is not shining di-
rectly on the screen or into the user’s eyes.
The optimal distance that a user should be from the Tobii PCEye Go mounted on a monitor/laptop differs depending on the size
of the screen. The user should be positioned at the optimal distance to allow for the best possible Gaze Interaction.
Generally, the larger the size of the screen, the greater the distance the user should be from the Eye Tracker / Screen combina-
tion for optimal Gaze Interaction.
Smaller than a 10 inch screen and larger than a 27 inch screen should not be used for optimal Gaze Interaction, for more infor-
mation see
Appendix D Technical Specifications, page 44 .
4.1.1 Track Box
The Tobii PCEye Go allows for extensi e Freedom of Head Mo ement. Once the Tobii PCEye Go is properly calibrated and
placed in front of the user, no further adjustments are required.
The Tobii PCEye Go produces an industry leading sized track box with the approximate dimensions of 30 cm × 20 cm × 20 cm
/ 11.8 in × 7.9 in × 7.9 in (Width × Height × Depth). The Track Box is an in isible box positioned approximately 60 cm (23.5 in)
straight out from a point just abo e the middle of the screen.
Tobii PCEye GoUser’s manual .2.1.1 - en-US 4 Using the Tobii PCEye Go 9

At 70 cm (27.5 in) the Tobii PCEye Go allows for lateral Freedom of Head Mo ement in an area of about 50 × 36 cm (20 × 14
in).
In order to function properly for Gaze Interaction the user needs at least one eye in the track box at all times.
4.1.2 Track Status Viewer
Use the Track Status iewer (see
4.1.2.1 Showing Track Status, page 10 for more information on how to open the Track Status
iewer) to help determine the optimal height and horizontal positioning for Gaze Interaction with the Tobii PCEye Go.
•Ideally, the two dots that represent the user’s eyes should be in the middle of the Track Status iewer.
•Use the distance meter on the right hand side of the Track Status iewer to determine the optimal distance the user
should be from the Tobii PCEye Go.
•The white triangle in the distance meter should ho er near the center, within the green, when the optimal distance from
the Tobii PCEye Go is reached.
For information about calibration of the Tobii PCEye Go see
5.2 Calibration, page 25 . Also check the lighting condi-
tions, related to what is mentioned abo e, when calibrating.
4.1.2.1 Sho ing Track Status
The track status iewer is a window/dialog where you can erify that the Gaze Interaction recognizes your eyes and that you are
well positioned in front of the de ice.
Open the track status iewer in one of the following ways:
•Open TToobbiiii GGaazzee IInntteerraaccttiioonn SSeettttiinnggss >> CCaalliibbrraattiioonn and select the TTrraacckk ssttaattuuss button.

4.1.3 Positioning Guide
For extra assistance in positioning, there is a PPoossiittiioonniinngg gguuiiddee that will show itself automatically in the bottom-right corner of
your monitor.
The PPoossiittiioonniinngg gguuiiddee is a isual guide that combines the function of the Track Status iewer with six different image based in-
structions to help the user with correct positioning.
10 4 Using the Tobii PCEye Go Tobii PCEye Go User’s manual .2.1.1 - en-US

The 6 instructions direct the user to:
1. Mo e head down.
2. Mo e head up.
3. Mo e head to the right.
4. Mo e head to the left.
5. Mo e head closer to the monitor.
6. Mo e head farther away from the monitor
