1 Introduction
Tobii PCEye Go User’s manual v.2.1.1 - en-US
2 Safety
The Tobii PCEye Go has been tested and approved 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 Device Directive (MDD) 93/42/EEC.Nevertheless, in order to ensure safe operation of your
Tobii PCEye Go device, there are a few safety warnings to bear in mind:
2.1 Mounting Warning
The Tobii PCEye Go should be mounted according to MANUFACTURER instructions of approved 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 adhesive Magnetic Mounting Plates is designed to permanently attach the
bracket to the monitor/laptop. Attempting to remove 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 above the head or face of a users unless using a dedicated
"fixed mounting" solution.
2.2 Emergency Warning
Be aware that due to the low, but possible, risk of failure, the Tobii PCEye Go 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 Go emits pulsed infrared (IR) light. Certain medical devices are susceptible to disturbance by IR light and/or radiation. Do not use the Tobii PCEye Go when in the vicinity of such susceptible medical
devices as their accuracy or proper functionality could be inhibited.
2.4 Epilepsy Warning
Some people with PPhhoottoosseennssiittiivvee EEppiilleeppssyy 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 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 Magnetic Field Warning
The Tobii PCEye Go Magnetic Mounting Plates contains magnets. Magnetic fields may interfere with the function of
cardiac pacemakers and implantable cardioverter-defibrillators. As a general rule, maintain a minimum distance of 6 inches (15 centimeters) between any item with magnets and your heart device.
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 v.2.1.1 - en-US

2.6 Child Safety
The Tobii PCEye Go 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.
2.7 Do not Open the Tobii PCEye Go
Non-compliance will result in loss of Warranty! There are no user serviceable 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
even a dryness of the eyes (due to less frequent blinking) when first getting used to Gaze Interaction. If you are experiencing fatigue or dry eyes start off slowly and limit the length of your Gaze Interaction sessions to your comfort level.
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 device 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 when Users Leaning Sideways or Those Lying Down
This means that for those users leaning sideways or those lying down the Tobii PCEye Go with monitor and computer device also 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 directly 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 combination 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 information see
Appendix D Technical Specifications, page 44
.
4.1.1 Track Box
The Tobii PCEye Go allows for extensive Freedom of Head Movement. 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 invisible box positioned approximately 60 cm (23.5 in)
straight out from a point just above the middle of the screen.
Tobii PCEye GoUser’s manual v.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 Movement 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 viewer (see
4.1.2.1 Showing Track Status, page 10
for more information on how to open the Track Status
viewer) 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 viewer.
• Use the distance meter on the right hand side of the Track Status viewer to determine the optimal distance the user
should be from the Tobii PCEye Go.
• The white triangle in the distance meter should hover 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 above, when calibrating.
4.1.2.1 Showing Track Status
The track status viewer is a window/dialog where you can verify that the Gaze Interaction recognizes your eyes and that you are
well positioned in front of the device.
Open the track status viewer in one of the following ways:
• Open TToobbiiii GGaazzee IInntteerraaccttiioonn SSeettttiinnggss >> CCaalliibbrraattiioonn and select the TTrraacckk ssttaattuuss button.
• Right-click (long-hold finger on icon for touch screen right clicking) on the TToobbiiii GGaazzee IInntteerraaccttiioonn SSeettttiinnggss icon,
,

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 visual guide that combines the function of the Track Status viewer with six different image based instructions to help the user with correct positioning.
10
4 Using the Tobii PCEye Go
Tobii PCEye Go User’s manual v.2.1.1 - en-US
The 6 instructions direct the user to:
1. Move head down.
2. Move head up.
3. Move head to the right.
4. Move head to the left.
5. Move head closer to the monitor.
6. Move head farther away from the monitor
Move head closer to the monitor. Move head to the right.
The PPoossiittiioonniinngg gguuiiddee will automatically disappear when the user’s positioning is improved in the way that is directed by the
guide.
Some users may not want the PPoossiittiioonniinngg gguuiiddee to pop up every time their eyes leave optimal positioning.
To turn On or Off the automatic PPoossiittiioonniinngg gguuiiddee, see
5.6 System Settings, page 35

4.2.3 Using Gaze Selection
The Gaze Selection mode of Windows Control makes it possible for the user to control a standard Windows desktop operating
system with a two step selection method which reduces the risks of unwanted clicks. It also prevents the following of the mouse
cursor with your gaze as opposed to the controlling of it (there is no floating mouse cursor in Gaze Selection).
1. The first step is to select the desired Task from the docked Taskbar by looking at it.
2. The second step is to look at the desired portion of the screen (or icon on the screen) where you want to execute the
Task. An automatic zoom function is enabled, ending in the selection of the icon or execution of the task.
4.2.3.1 Gaze Selection Taskbar
At the top of the Gaze Selection Taskbar there is a Track Status viewer. It allows you to verify that the eye tracker recognizes your
eyes and that you are well positioned in front of the device.
The Task Buttons in the Gaze Selection Taskbar can be in three different modes as shown in
Figure 4.3 The Modes for the Gaze
Selection Taskbar, page 13
.
• NNoorrmmaall ((UUnnsseelleecctteedd)) - No Task Button for Gaze Selection is chosen.
• PPrriimmaarryy SSeelleeccttiioonn ((BBlluuee//bbllaacckk)) - The marked Task Button is selected and the Task will be executed after the automatic
zoom when the user looks at the desired position on the screen or icon on it. If the selection method is set to Switch in
the Gaze Selection Settings Dialog, the chosen Task Button will still remain active after executing the Task.
The Functions Overlay Task will not perform any zooming. When selecting Functions Overlay with Primary Selection, the Functions Areas/Commands will be active but not visible.
• SSeeccoonnddaarryy SSeelleeccttiioonn((BBlluuee//wwhhiittee)) - Same as PPrriimmaarryy SSeelleeccttiioonn but with a higher precision. PPrriimmaarryy SSeelleeccttiioonn
means that the zoom will progress deeper before the final execution of the Task, making the desired portion of the screen
bigger and easier to select within. Activate this mode by resting your gaze on the Task Button until the color changes according to the image below.

4.2.3.5 Selection Methods — Gaze and Switch
There are two methods to execute the chosen Task. The method of choice is set from within the Gaze Selection Settings Dialog,
see
6 Gaze Selection Settings, page 37
.
Before executing a selection you select a Task from the Taskbar to execute. Gaze at your chosen task until it is highlighted as
“Primary” or “Secondary Selection”.
• GGaazzee - To execute the chosen Task, rest your gaze at the desired portion of the screen (or icon on the screen) where
you want to execute the Task. An automatic zoom function is enabled, ending in the selection of the icon or execution of
the task.
• SSwwiittcchh - Two different execution modes.
– SSiinnggllee aaccttiivvaattiioonn ooff tthhee SSwwiittcchh - the zoom function will execute in the same way as with the Gaze method and ac-
cording to the settings made in the Gaze Selection Settings Dialog, see
6 Gaze Selection Settings, page 37
.
– AAccttiivvaattee aanndd hhoolldd tthhee SSwwiittcchh - the zoom function will zoom continuously and end only upon the release / deactiva-
tion of the switch.
The Functions Overlay will not perform any zoom.
When using the Gaze method, you have to look back to the Taskbar to select a new Task after the execution of the
Task, even if it is the same as you have just used.
When precision is set to zero in Gaze Selection Settings - no zoom is performed. For more information, see
6 Gaze
Selection Settings, page 37
.
4.2.3.5.1 Sticky Tasks & Default Left Click / Tap for Switch
When using the Switch method, a feature is made use of called "sticky tasks". If a Task becomes "sticky" it means that you do
not have to look back at the Taskbar if you want to repeat the execution of the selected Task, only if you want to change the Task
to another.
When using the Switch method, the Left Click / Tap Task is "sticky" by default. This means that Left Click / Tap is always on and
will always be activated by the activation of the switch, if nothing else is selected. If another Task is selected it will be active only
once (for one selection) and then Gaze Selection will automatically default back to Left Click / Tap for the subsequent
selections.
The exception to this is the Double Click Task; when it is selected when using Switch mode it will also become sticky, meaning
that it will stay selected until another Task is selected (after which it will again default back to Left Click / Tap).
Tobii PCEye GoUser’s manual v.2.1.1 - en-US
4 Using the Tobii PCEye Go
19
This allows for excellent use cases such as quick/continual surfing of the internet by activating the Switch and thus the Left Click
/ Tap Task once and then repeatedly selecting anything desired, without having to choose the Left Click /Tap Task again multiple
times.
4.2.3.5.2 Activating a Task with a Keyboard button instead of a Switch
Selecting the “F12 Keyboard Button”,
, on an attached keyboard will activate a Task selection. It can be used in exactly the
same way as a connected switch. For more information on Switches, see
4.2.3.5 Selection Methods — Gaze and Switch, page
19
.
4.2.3.6 Gaze Keyboard
By selecting the Gaze Keyboard button on the Taskbar, the Gaze Keyboard will launch as an on-screen keyboard. The Gaze
Keyboard will be positioned either at the top or at the bottom of the screen depending on where the user has placed the last
mouse click (or last cursor position) before launching the Gaze Keyboard. The keyboard will place itself on the opposite side from
where the mouse/cursor is.
The Gaze Keyboard consists of four keyboard pages in a rotating loop. The user can easily switch between the different keyboard pages by selecting the next page buttons located to the far left and right on all pages of the Gaze Keyboard.
The key on the keyboard where the user is looking will be indicated by a light frame around the character/function on the key.
While the user is typing, the last 5-10 characters will be displayed in blue on the indicated/highlighted key. This feature assists
the user in easily spotting misspellings and reduces the need for looking at the actual spot where the text is inserted, thus increasing typing speed.
The four keyboard pages are:

The Shift, Ctrl, Alt, Win and Alt Gr keys will become "sticky" once selected. This means that they will stay selected until
the user selects a new key from the keyboard. They will stay sticky if the next selected key is another sticky key.
To write a letter with an accent:
1. Select the accent
2. Select the character
3. The character will appear with the chosen accent.
The Number keys in the keyboard are positioned as on a Number Pad and can be used in combination with the Alt key
to write ASCII characters.
1. Select the Alt key
2. Select the number combination for the ASCII character
3. Select the Alt key
4. The ASCII character will appear.
To delete a full word at a time instead of one character at a time:
1. Select the Ctrl key
2. Select the Backspace key
4.2.3.7 Gaze Selection in Combination with Region Based Keyboards
Gaze Selection can be used in combination with other eye controlled applications. "Gaze Enabled" regions in other applications
are active as long as there is no active Task in the Gaze Selection Toolbar. If you are using Gaze Selection with switch the Task
Buttons will be "sticky", if you need to deselect a Task just look back at the selected Task for a short moment.

5.2.4 Improving Calibration Point(s)
After calibration, you may want to improve one or more points.
There is a color scheme used that will help you to understand the quality of your calibration.
All three color statuses are the result of a ssuucccceessssffuull calibration.
• If the background color of the Calibration Result is light red, you have achieved a successful, but relatively low quality calibration. You can improve one or more points individually, or recalibrate completely, to achieve better Gaze Interaction
results.
Improving even one (or more) of the calibrations points can significantly improve the calibration.
• If the background color of the Calibration Result is light yellow, you have achieved successful and good quality calibration. You might be able achieve better Gaze Interaction results by improving one or more points individually.
• If the background color of the Calibration Result is green, you have achieved a successful and high quality calibration.
Be aware that no matter what quality of calibration you have achieved you will be able to select OOKK or AAppppllyy and begin
using Gaze Interaction. It is the accuracy and functionality of the Gaze Interaction that is affected by the quality of the
calibration results. Try for the best calibration possible.
RReemmeemmbbeerr!! In the end it is the personal experience that counts!
The closer the lines within the calibration point are to a dot in the center of the circle of the calibration point, the better the cali-
bration is of that point,
.You can choose the points to be improved and calibrate only those points again.
To improve one or more calibration points, follow these steps :
1. Open TToobbiiii GGaazzee IInntteerraaccttiioonn SSeettttiinnggss >> CCaalliibbrraattiioonn.
2. Select the point(s) you want to improve under CCaalliibbrraattiioonn RReessuulltt.
3. Select the IImmpprroovvee PPooiinntt((ss)) button and a calibration for the selected point(s) will start.

5.2.5 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 Gaze Interaction will not function properly there.
To remove one or more calibration points, follow these steps:
1. Open TToobbiiii GGaazzee IInntteerraaccttiioonn SSeettttiinnggss >> CCaalliibbrraattiioonn.

i. Freedom of head movement describes the volume in front of the tracker in which the user must have at least one of the eyes. The numbers are
specified parallell/orthogonal to screen surface, assuming eye tracker is at 20 degree angle to screen.
ii. Gaze accuracy describes the angular average distance from the actual gaze point to the one measured by the eye tracker.
Accuracy under ideal conditions is measured with users placed in the center of the eye tracker track box with the head resting on a chin rest, and the
room and screen illumination constant at 300 lux.
Accuracy across head box is measured with users after calibration systematically positioned at varying positions ranging from center of the head box up
to ± 15 cm horizontal, ± 10 cm vertical and ± 10 cm distance.
