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 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. 1.3.11 Keeping Tobii Glasses Controller Software and the Recording Unit firmware up to date From time to time Tobii will release updates for the eye tracker firmware and Tobii Glasses Controller Software that will improve performance and/or introduce new functionality.

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.

Tobii Glasses 2 Eye TrackerUser’s manual v.1.0.2 - en-US 7 Basic Operations with Tobii Glasses 2 31 7.12.2 Tobii Glasses 2 data structure Data from a Tobii Glasses 2 recording is contained in “studies”. Each study contains general study details, participant data and recording data. Since both Tobii Glasses Controller Software and the Recording Unit can generate and store data in a given study, data is automatically synchronized between the two units whenever there is a connection between them. As seen in the table below, scene camera video and full recording data (including all eye tracking data) is ONLY stored on the Recording Unit SD card (SD); all other data is stored both on the Recording Unit SD card and on the tablet/computer running Tobii Glasses Controller Software (TGCS). Type Container Data Data is stored Study name SD + TGCS Date created SD + TGCS Participant name SD + TGCS Participant info SD + TGCS Names of associated recordings SD + TGCS Recording name SD + TGCS Scene camera video SD Full Recording data set (Eye tracking data) SD Duration SD + TGCS Eye tracking quality SD + TGCS Recording date SD + TGCS Study General Participant Recording 7.12.3 Displaying the Glasses Control Panel Properties Every Recording Unit has its own Device name, Serial number, Firmware version etc. This information is accessible in Glasses Control Panel Properties on the Dashboard in Tobii Glasses Controller Software. To display Glasses Control Panel Properties: 1. Locate the Glasses Control Panel for the relevant Recording Unit on the Dashboard. 2. Tap the Properties icon in the bottom left hand corner of the Glasses Control Panel.

Tap Rename Glasses in Glasses Control Panel Properties . 3. Type a new name and tap Save Changes. 7.12.5 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. SD memory cards provided by Tobii can be used directly without any formatting. If for any reason (data deletion, malfunction, etc) a memory card must be formatted, this is done from a Windows computer. Make sure to format the SD card as FAT32. 7.13 Tobii Glasses Controller Software considerations and limitations 7.13.1 Dashboard information Information on the Glasses Control Panel is synchronized with a Recording Unit as long as the software is running and there is a connection between the tablet/computer. There are cases when they are not connected to each other which might cause the information on the Dashboard to be misleading. If a recording that was started by one tablet/computer is stopped by another tablet/computer, the Glasses Control Panel of the tablet that started the recording will state that the Glasses are still recording. When connection is re-established, the information on the Dashboard will be updated. The same is true if a Recording Unit runs out of battery or space on the SD card. 7.13.2 Anyone running Tobii Glasses Controller Software can connect and control any Tobii Glasses Recording Unit. There are no means of locking a Recording Unit to one or several tablets or licenses of Tobii Glasses Controller Software. Anyone who has Tobii Glasses Controller Software installed on a Windows computer or tablet can potentially connect and control any Recording Unit. 7.13.3 Editing or removing participants from a Study Participants cannot be edited or removed from the Participants List. If, for any reason a faulty participant is added to the Participants List, ignore this participant and add a new Participant with the correct data. Tobii Glasses 2 Eye TrackerUser’s manual v.1.0.2 - en-US 7 Basic Operations with Tobii Glasses 2 33 8 Advanced Usage with Multiple Units In most research scenarios one tablet/computer connects to one Tobii Glasses 2 Recording Unit. There are scenarios where one would like to connect one tablet to multiple Recording Units, or multiple tablets to one or more Recording Units. The Recording Unit works as a network access point and multiple tablets running Tobii Glasses Controller Software can connect to it simultaneously. The opposite, one tablet/computer connected to multiple Recording Units, is however limited by the number of network hardware devices in the computer. To connect multiple Recording Units to one tablet/computer, a router or switch must be used, along with Ethernet cables between the Recording Units and the router/switch. In this case the switch becomes the access point rather than the Recording Units. Known issues when connecting multiple tablets/computers to the same Recording Unit: • • 34 If commands are sent from several instances of Tobii Glasses Controller Software to the same Recording Unit, the Recording Unit may receive conflicting instructions and may stop reacting. The bandwidth may be insufficient to allow for several instances of Tobii Glasses Controller Software to allow live viewing of an ongoing recording. 8 Advanced Usage with Multiple Units Tobii Glasses 2 Eye Tracker User’s manual v.1.0.2 - en-US 9 9.1 Accessories Tobii Glasses 2 Carry Case Tobii Glasses 2 comes with a dedicated Carry Case that will accommodate the most important components needed for data collection with Tobii Glasses 2, including the Head Unit, Recording Unit, SD memory cards, batteries, etc. See the illustration (below right)and the table below for information about how to fit the equipment in the Carry Case.
