2 IntroductionTobii Glasses 2 is designed to enable easy, precise and efficient collection of eye tracking data in a wide variety of researchscenarios. The discreet, ultra-lightweight design ensures natural behavior and research validity in both qualitative and quantita-tive real-world research. Accurate data and robust eye tracking capabilities can be relied on in uncontrolled situations and real-world environments.2.1 Intended useTobii Glasses 2 is intended to be used in research activities about human behavior including eye movements, involving adultparticipants 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 overviewThe Tobii Glasses 2 eye tracking system is designed to be used for research purposes with adult participants and it includesthe lightweight Tobii Glasses Head Unit, a wearable Recording Unit and Tobii Glasses Controller Software running on a Win-dow 8 Pro tablet or any Windows 8/8.1 or Windows 7 computer. The tablet/computer may or may not be included in the ship-ment 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 standardpair of glasses). The system must then be calibrated separately for each participant. In the calibration process the test partici-pant is asked to look at a Calibration Card held in-front of the participant for a few seconds. The researcher then starts the re-cording 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 withthe eye tracker (adding participants to test, initiating calibration, starting/stopping recordings etc.) are done through TobiiGlasses Controller Software. The controller software also enables the researcher to view the eye tracking session both in real-time (streamed through a wireless or wired connection) and after the recording. When viewing a recording, the participant’sgaze point appears as a colored dot on the scene camera video from the HD camera integrated in the Tobii Glasses 2 HeadUnit.For any eye tracking analysis beyond looking at the eye tracking replay (as described above), recorded data must be transferredto a computer running Tobii Glasses Analysis Software. Tobii Glasses Analysis Software runs on Windows computers and mustbe 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 2 Introduction 7

7.12.2 Tobii Glasses 2 data structureData from a Tobii Glasses 2 recording is contained in “studies”. Each study contains general study details, participant data andrecording data. Since both Tobii Glasses Controller Software and the Recording Unit can generate and store data in a givenstudy, data is automatically synchronized between the two units whenever there is a connection between them. As seen in thetable below, scene camera video and full recording data (including all eye tracking data) is ONLY stored on the Recording UnitSD card (SD); all other data is stored both on the Recording Unit SD card and on the tablet/computer running Tobii GlassesController Software (TGCS).Container Type Data Data is storedStudyGeneralStudy name SD + TGCSDate created SD + TGCSParticipantParticipant name SD + TGCSParticipant info SD + TGCSNames of associatedrecordingsSD + TGCSRecordingRecording name SD + TGCSScene camera video SDFull Recording data set (Eyetracking data)SDDuration SD + TGCSEye tracking quality SD + TGCSRecording date SD + TGCS7.12.3 Displaying the Glasses Control Panel PropertiesEvery Recording Unit has its own Device name, Serial number, Firmware version etc. This information is accessible in GlassesControl Panel Properties on the Dashboard in Tobii Glasses Controller Software.To display Glasses Control Panel Properties:1.

2. Tap Rename Glasses in Glasses Control Panel Properties .3. Type a new name and tap Save Changes.7.12.5 Memory cardsSD memory cards used in the Tobii Glasses 2 Recording Unit must be formatted as FAT32. SDHC cards are usually pre-for-matted as FAT32 and will work out of the box while SDXC cards must be formatted as FAT32 before they can be used with theRecording 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 asFAT32.7.13 Tobii Glasses Controller Software considerations and limitations7.13.1 Dashboard informationInformation on the Glasses Control Panel is synchronized with a Recording Unit as long as the software is running and there isa connection between the tablet/computer. There are cases when they are not connected to each other which might cause theinformation on the Dashboard to be misleading. If a recording that was started by one tablet/computer is stopped by anothertablet/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 runsout of battery or space on the SD card.7.13.2 Anyone running Tobii Glasses Controller Software can connect and control any TobiiGlasses Recording Unit.There are no means of locking a Recording Unit to one or several tablets or licenses of Tobii Glasses Controller Software. Any-one who has Tobii Glasses Controller Software installed on a Windows computer or tablet can potentially connect and controlany Recording Unit.7.13.3 Editing or removing participants from a StudyParticipants cannot be edited or removed from the Participants List. If, for any reason a faulty participant is added to the Partici-pants 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 UnitsIn most research scenarios one tablet/computer connects to one Tobii Glasses 2 Recording Unit. There are scenarios whereone 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 con-nect to it simultaneously. The opposite, one tablet/computer connected to multiple Recording Units, is however limited by thenumber of network hardware devices in the computer. To connect multiple Recording Units to one tablet/computer, a router orswitch must be used, along with Ethernet cables between the Recording Units and the router/switch. In this case the switch be-comes the access point rather than the Recording Units.Known issues when connecting multiple tablets/computers to the same Recording Unit:•If commands are sent from several instances of Tobii Glasses Controller Software to the same Recording Unit, the Re-cording 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 view-ing of an ongoing recording.34 8 Advanced Usage with Multiple Units Tobii Glasses 2 Eye Tracker User’s manual v.1.0.2 - en-US
