Chapter 1 Introduction
Introduction
Thank you for purchasing a Tobii PCEye device from Tobii Technology!
To ensure the optimal performance of this product, please take the time to read this
manual carefully.
This User’s Manual covers:
• The PCEye device and its use.
• The Tobii Eye Control Suite program (for enabling the use of eye control on
your PC Computer).
1.1 Intended Use
The Tobii PCEye module is an eye control unit which is designed to dock, using its
mounting bracket, under retail PC computer screens. The PCEye module allows you
use eye control to operate your personal computer with precision regardless of glasses,
contact lenses, eye color or light conditions. Simply, it enables you to control your
computer with your eyes. By looking at the screen, you control the mouse pointer and
click by blinking, dwelling (staring at the screen for a certain length of time) or using a
Switch.
When used in combination with communications software the PCEye allows
Augmentative and Alternative Communication (AAC) users the ability to achieve their
full potential through eye control. Using the eye control offered by the PCEye a user
can communicate via text or symbols to generate synthesized (computer voice) or
digitized (recorded voice) speech for face-to-face communication. A user also has the
option of communication through e-mail, text messages and chat and has the freedom
and exibility to write and edit documents, surf the Internet, or play music and games, If
used in conjunction with communications software and an environmental control unit,
users can also use the PCEye’s eye control to control a TV, DVD and other household
appliances via IR remote control.
When used in conjunction with communications software the PCEye device is
not intended as the sole communication means for a user but as a complementary
communication solution. Low-tech and no-tech Augmentative and Alternative
Communication (AAC) solutions used as additional methods are recommended as best
practice for any person utilizing a high-tech AAC device.

Safety
The Tobii PCEye has been tested and approved as compliant to all the
Specications and Standards listed in the 6.2 Appendix B: Compliance
Information section of this manual and in the 6.3 Appendix C: Technical
Specications section -- including, but not limited to, the Medical Device
Directive (MDD) 93/42/EEC. Nevertheless, in order to ensure safe operation of
your Tobii PCEye device, there are a few safety warnings to bear in mind:
2.1 Mounting Warning
The PCEye devices should be mounted according to instructions for approved mounts
or mounting brackets (see 3 Getting Started > 3.2 Mounting the PCEye to
your PC Monitor). However, should the device for any reason harm or damage
someone or something due to falling or other. Neither Tobii Technology nor any of its
representatives will be responsible or liable for any damages or injuries which may arise.
The mounting of the PCEye is done entirely at the user’s own risk.
2.2 Emergency Warning
Be aware that due to the low, but possible, risk of failure, the Tobii PCEye should not be
relied upon exclusively as an audio communications, or an environmental control, device
in emergencies, as well as in dangerous, or otherwise important, situations. Do not
rely on the device for emergency calls or banking transactions. We recommend having
multiple ways to communicate in emergency situations. Banking transactions should only
be carried out with a system recommended by, and approved according to the standards
of, your bank.
2.3 Infrared Warning
When activated, the Tobii PCEye emits pulsed infrared (IR) light. Certain medical devices
are susceptible to disturbance by IR light and/or radiation. Do not use the PCEye when in
the vicinity of such susceptible medical devices as their accuracy or proper functionality
could be inhibited.

Chapter 2 Safety & Compliances
2.4 Epilepsy Warning
Some people with Photosensitive Epilepsy are susceptible to epileptic seizures or
loss of consciousness when exposed to certain ashing 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 ickering uorescent 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 during use, move your eyes away from the eye tracker.
2.5 Electricity Warning
Do not open the casing of the PCEye device, since you may be exposed to potentially
hazardous electrical voltage. The device contains no serviceable parts.
2.6 Magnetic Field Warning
The PCEye Mounting Bracket contains magnets. Magnetic elds may interfere with the
function of cardiac pacemakers and implantable cardioverter-debrillators. As a general
rule, maintain a minimum distance of 6 inches (15 centimeters) between any item with
magnets and your heart device.
2.7 Child Safety
The Tobii PCEye is an advanced computer system and electronic device. As such it is
composed of numerous separate, assembled parts. In the hands of a child certain of
these parts have the possibility of being separated from the device, possibly constituting a
choking hazard or another danger to the child.
Young children should not have access to, or the use of, the device without parental or
guardian supervision.

Using the PCEye
4.1 Positioning
The mounted PCEye Module attached to its stand and to your device is designed to
work optimally when it is parallel to the user’s eyes at a distance from about 50 to 80 cm
(19.7 to 31.5 in). This means that for those users leaning sideways or those lying down the
PCEye with its stand and computer device also needs to be tilted in order to keep the
users eyes parallel to the screen and at the optimal distance.
50 - 80cm
90°
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 Eye Tracking
performance, will be enhanced if the sun is not shining directly on the screen or into the
user’s eyes.
Some people may experience a certain amount of fatigue (due to intentional eye focusing
and hard concentration) or even a dryness of the eyes (due to less frequent blinking)
when rst getting used to eye tracking. If you are experiencing fatigue or dry eyes
start off slowly and limit the length of your eye tracking sessions to your comfort level.
Remoisturizing eye drops can be helpful to combat dryness.
4.1.1 Screen Size and Optimal Distance
The optimal distance that a user should be from the PCEye mounted on a monitor
differs depending on the size of the screen. The user should be positioned at the optimal
distance to allow for the best possible eye tracking and eye control.

individually, or recalibrate completely, to achieve better eye tracking results.
• If the background color of the Calibration Result is light yellow, you have
achieved a medium quality calibration. You might be able achieve better eye
tracking results by improving one or more points individually.
• If the background color of the Calibration Result is green, you have achieved a
high quality calibration.
Be aware that no matter what quality of calibration you have achieved you will be able to

calibration points by:
1. Opening Tobii Eye Control Options > Eye Tracking.
2. Under Calibration Result marking the point(s) you want to improve.
3. Clicking Improve Point(s) and a calibration for the selected point(s) will start.
4.9.5 Removing Calibration Point(s)
If there is a calibration point that is consistently bad after calibration (the green lines
are scattered all around and outside the circle of the calibration point) you can remove
that point completely from the calibration, this may improve the calibration of the other
points. Be aware that if you remove a point, that area of the screen will be uncalibrated
and eye tracking will not function properly there.
Remove one or more calibration points by:
1. Opening Tobii Eye Control Options > Eye Tracking.
