1 On Safety
1.1 Intended Use
Tobii Pro Mobile Device Stand is designed to be used only with Tobii Pro X2-30/X2-60/X3-120/Nano Eye Tracker (no other
types of eye trackers can or should be used with the stand). s with the Pro X2-30/X2-60/X3-120/Nano eye trackers, the stand
is intended only for use in office environments. Read this User’s Manual carefully before assembling or using the stand.
1.2 Mounting Warning
Pro Mobile Device Stand is designed to be mounted on a table. Be careful when mounting or using the stand so as
not to cause injury or damage. Make sure the stand is assembled correctly and that the eye tracker is properly fitted
on the stand before use to avoid damaging the stand, the eye tracker or the test participant. ssembly instructions
are on page 5.
1.3 Usage Warning
Please follow the instructions in this User’s Manual carefully. If incorrectly assembled or used, the eye tracker or parts
of Tobii Pro Mobile Device Stand can be damaged and may even cause injuries. Should the device for any reason
harm someone or damage something due to falling or other incident, neither Tobii nor any of its representatives will
be responsible or liable for any damages or injuries that may arise. Mounting and use of the stand is done entirely at
the user’s own risk.
When using and adjusting the angle of the Tobii Pro Mobile Device Stand, be careful so as not to injure the test par-
ticipant or yourself as there is a risk of squeezing objects or fingers between moving parts. The scene camera holder
and other parts of the product may cause injury if it strikes the head or other body parts.
1.4 Small Parts Warning
Pro Mobile Device Stand is composed of numerous separate, assembled parts. In the hands of a child some of these
parts may become unattached and may possibly constitute a choking hazard or other danger to the child. Young chil-
dren and animals should not have access to or use the device without parental or guardian supervision.

2 Product Description
2.1 Intended use
The Pro Mobile Device Stand is designed to be used with a Pro X2-30/X2-60/X3-120/Nano Eye Tracker (no other types of eye
trackers can or should be used together with the stand), and a Windows computer running the Tobii Studio or Tobii Pro Lab
software.
Note: No eye tracker, computer or software license is included.
n entire mobile device testing solution comprises a Pro Mobile Device Stand, one Pro X2-30, X2-60, X3-120, or Nano eye
tracker and the computer running Tobii Studio or Pro Lab. The compatibility between Tobii Pro eye trackers and Tobii Pro soft-
ware is listed in the Compatibility Table in chapter 4, page 13.
The Tobii Mobile Device Testing Solution enables collection of eye tracking data during natural interaction with smartphones,
tablet computers and other devices or objects of similar size such as books or brochures. The tested device (e.g. smartphone
or tablet) is attached to a supplied holder using adhesive mounting putty or a Nanopad to keep the device in the correct position
throughout data collection. The holder allows participants to switch the device orientation between landscape and portrait
mode.
The stand is delivered with all necessary equipment for eight different configurations optimized for different devices and setups.
ll equipment fits into the supplied travel case. The stand includes an adjustable scene camera (that points at and films the mo-
bile device) to enable capturing of user actions and the user interface (Eye tracking data will be superimposed on images and
video captured with the scene camera in the analysis software, Tobii Studio or Pro Lab). Sound can also be recorded though
the scene camera to be played back in Tobii Studio or Pro Lab. The stand and one eye tracker fits in the supplied travel case
which is designed for easy transportation of the entire solution.
The mobile device stand supports both Pro X2 and X3 product families, as well as the Pro Nano eye tracker. The package in-
cludes a Pro X3-120 Eye Tracker compatibility kit (adapter plate and a 1.8 m long USB 3 cable) for use with a Pro X3–120 eye
tracker. This adapter plate is also compatible with the Tobii Pro Nano eye tracker. The Pro X3–120 Eye Tracker compatibility kit
is also available to buy separately for clients already in possession of a Pro X2 Mobile Device Stand; please contact Tobii Sales
for more information.

2.3.2 Tobii Pro X3 compatibility kit
The compatibility kit for Pro X3 consists of one mounting adapter for both the Pro X3–120 Eye Tracker and the Pro Nano Eye
Tracker (see image above) and one 1.8 m USB 3 cable. These two items can be ordered separately for users of the previous
X2 only MDS package.
2.4 Considerations
The Pro Mobile Device Stand is designed to make optimal use of the Tobii Pro eye tracker (X2-30, X2-60, X3-120, Pro Nano)
in mobile device testing. To ensure superior quality of the collected eye tracking data, please consider the following sections.
2.4.1 Light Conditions
We recommend you conduct your eye tracking study in a controlled and well-lit environment. Sunlight contains high levels of in-
frared light that will interfere with the eye tracker system and should be avoided.
2.4.2 Eyelashes
Eyelashes can be obstructive when the participants’ eyes are less open, especially if participants are wearing mascara. In rare
cases, the eyelashes can completely block the view of the participant´s pupils, making eye tracking impossible.
2.4.3 Droopy Eyelids
Droopy eyelids or otherwise obstructive eyelids can block the view of the participant´s pupils. In rare cases such eyelids may
completely block the view of the participant´s pupils, making eye tracking impossible.
2.4.4 Glasses and Contact Lenses
Participants with bifocal or progressive glasses should be screened out, or asked to remove their glasses. Bifocals and progres-
sive glasses may reduce accuracy. Contact lenses may slightly increase noise but do not normally introduce any error into the
data. Colored or fancy lenses that change the appearance of the pupil or iris should be avoided as they may make eye tracking
impossible.
