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.
