1.3 Other limitations and considerations
1.3.1 Intended use
Tobii Glasses 2 is intended to be used in research activities about human behavior including eye movements, involv-
ing adult participants in a dry and dust free indoor environment. The product should only be used as described in the
User’s Manual. Please read the User’s Manual and other supplied documentation thoroughly before using the
product.
1.3.2 SD memory cards
SD memory cards used in the Tobii Glasses 2 Recording Unit must be formatted as FAT32. SDHC cards are usually
pre-formatted as FAT32 and will work out of the box while SDXC cards must be formatted as FAT32 before they can
be used with the Recording Unit. Only use SD cards recommended by or supplied by Tobii.
1.3.3 Multiple connections between Glasses Controller Software and Recording Unit
Under no circumstances should the tablet or computer running Tobii Glasses Controller Software connect to the
same Recording Unit using both a wireless and a wired connection at the same time.
1.3.4 Eye movement classification
Gaze presented in the Live Viewer and replay tabs of Tobii Glasses Controller Software is filtered through a five-point
moving average filter. Such filters do not entirely mimic true eye movement behavior and fixations may seem to dynam-
ically shift locations. This has no significant impact for qualitative observational analysis in Tobii Glasses Controller
Software. When data is transferred to Tobii Glasses Analysis Software, only raw, unfiltered data is transferred, giving
the analyst full access to more advanced eye movement classification filters suitable for quantitative analysis of gaze
data.
1.3.5 Light conditions
We recommend that eye tracking studies be performed in a controlled and well-lit environment. Sunlight should be
avoided since it contains high levels of infrared light which will interfere with the eye tracker system. Sunlight affects
eye tracking performance severely and longer exposure can overheat the eye tracker. The eye tracker is not designed
for exposure to (direct) sunlight. Eye tracking generally does not work in strong direct sunlight. Shielding the eye
tracker adequately from the sun may prevent sunlight from interfering with eye tracking. For better performance, use
the supplied tinted lenses if the product is used in an environment with strong sunlight..
1.3.6 Eyelashes
Long eyelashes can be obstructive when the participant’s eyes are less open, especially if the participant is wearing
mascara. In rare cases, eyelashes may completely block the view of the participant’s pupils, making eye tracking
impossible.
