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, involving 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 dynamically 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.
Tobii Glasses 2 Eye TrackerUser’s manual v.1.0.2 - en-US
1 Safety and Compliance
5
1.3.7 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.
1.3.8 Eye glasses and contact lenses
Tobii Glasses 2 is not designed to work in conjunction with standard eye glasses. Participants who wear eye glasses
should be screened out, or asked to remove their own glasses before wearing the Head Unit.
Standard contact lenses may slightly increase noise but do not normally introduce any errors in the data. Colored or
fancy lenses that change the appearance of the pupil or iris should be avoided as they might make eye tracking
impossible.
1.3.9 WLAN connectivity
WLAN signal quality is affected by different environmental factors such as the distance between the Recording Unit
and the tablet/computer, the presence of walls, windows, furniture and other objects, and the presence of other
WLAN devices and networks in the same area. A weak or low quality WLAN signal will decrease the quality of, or
even interrupt the Live Viewing video in Tobii Glasses Controller Software or even disconnect the Recording Unit
from the tablet/ computer.
1.3.10 Power
We recommend that you connect the power cord of the chargers to an outlet with a protective earth/ground connection. Use an accessible outlet and make sure the cords are properly placed to avoid the risk of tripping. Never use
damaged power cords.

Tobii Glasses 2 Eye Tracker User’s manual v.1.0.2 - en-US
2 Introduction
Tobii Glasses 2 is designed to enable easy, precise and efficient collection of eye tracking data in a wide variety of research
scenarios. The discreet, ultra-lightweight design ensures natural behavior and research validity in both qualitative and quantitative real-world research. Accurate data and robust eye tracking capabilities can be relied on in uncontrolled situations and realworld environments.
2.1 Intended use
Tobii Glasses 2 is intended to be used in research activities about human behavior including eye movements, involving 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.
2.2 Usage overview
The Tobii Glasses 2 eye tracking system is designed to be used for research purposes with adult participants and it includes
the lightweight Tobii Glasses Head Unit, a wearable Recording Unit and Tobii Glasses Controller Software running on a Window 8 Pro tablet or any Windows 8/8.1 or Windows 7 computer. The tablet/computer may or may not be included in the shipment depending on what package was purchased.
To record eye tracking data, the Tobii Glasses Head Unit must be fitted onto the test participant’s head (similar to a standard
pair of glasses). The system must then be calibrated separately for each participant. In the calibration process the test participant is asked to look at a Calibration Card held in-front of the participant for a few seconds. The researcher then starts the recording from Tobii Glasses Controller Software running on a Windows 8/8.1 Pro tablet or any Windows 8/8.1 or 7 computer.
After the session, the researcher stops the recording and removes the head unit from the test participant. All interactions with
the eye tracker (adding participants to test, initiating calibration, starting/stopping recordings etc.) are done through Tobii
Glasses Controller Software. The controller software also enables the researcher to view the eye tracking session both in realtime (streamed through a wireless or wired connection) and after the recording. When viewing a recording, the participant’s
gaze point appears as a colored dot on the scene camera video from the HD camera integrated in the Tobii Glasses 2 Head
Unit.
For any eye tracking analysis beyond looking at the eye tracking replay (as described above), recorded data must be transferred
to a computer running Tobii Glasses Analysis Software. Tobii Glasses Analysis Software runs on Windows computers and must
be purchased separately. Tobii Eye Trackers are designed for use in indoor office environments.
