1 Introduction
|
||
Tobii Pro 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 real- world environments.
|
||
1.1 Intended use
|
||
Tobii Pro 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 manual.
|
||
Please read the User’s Manual and other supplied documentation thoroughly before using the product.
|
||
|
||
1.2 Usage overview
|
||
The Tobii Pro Glasses 2 eye tracking system is designed to be used for research purposes with adult participants and it includes the lightweight Tobii Pro Glasses Head Unit, a wearable recording unit and Tobii Glasses Controller Software running on a Windows 8 and later Pro tablet, or any Windows 7 or later 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 inront of the participant for a few seconds. The researcher then starts the recording from Tobii Glasses Controller Software running on a Windows 8 or later Pro tablet or any Windows 7 or later 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/hear the eye tracking session both in real-time (streamed through a wireless or wired connection) and after the recording. When viewing a recording, you can hear what was recorded on the integrated microphone of the Tobii Pro Glasses 2 Head unit, the participant’s gaze point also appears as a colored dot on the scene camera video from the Full HD camera integrated in the Tobii Pro 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 Controller Software is designed to be installed on a Windows 8 or later Pro tablet but can also be installed on any Windows 7 or later computer. Please refer to the System Recommendations document for the most current computer re- quirements for Tobii Glasses Controller Software.

4.5 Epilepsy warning
|
||
Some people with photosensitive epilepsy (PSE) are susceptible to epileptic seizures or loss of consciousness when exposed to certain flashing lights or light patterns in everyday life. This may happen even if the person has no medical history of epilepsy or has never had any epileptic seizures.
|
||
A person with PSE would also be likely to have problems with TV screens, some arcade games, and flickering fluorescent bulbs. Such people may have a seizure while watching certain images or patterns on a monitor, or even when exposed to the light sources of an eye tracker. It is estimated that 3 to 5% of those diagnosed with epilepsy have this type of epilepsy. Many people with PSE experience an "aura" or odd sensations before a seizure occurs. If you, or the wearer of the head unit, feel odd during use, turn off and remove the head unit.

|
||
5.1.5 Prescription Lenses
|
||
In order to accommodate the head unit to a larger user audience, Tobii has developed a set of dedicated prescription lenses, supplied as a separate kit (optionally available), for correction of either short-sightedness or long-sightedness. The prescription lenses are magnetically fitted onto an adapter on the head unit and the participant can then walk around freely with a corrected sight. The set also contains two zero strength lenses for both the right and left side for use in the case the participant only need correction on one side. Included in the kit is one spare magnetic attachment adapter and a convenient storage compartment for the participant’s own glasses to keep them well protected during the survey. The procedure for selecting suitable prescription lenses is easy and straight-forward. Either the participant is already aware what glasses strength he/she uses, if so, it is easy to fit the prescription lenses of the corresponding correction value. If the participant does not know, the kit contains a reading chart that assists you in selecting the most suitable correction strengths.
|
||
The addition of a lens element in front of the head unit may create a small optical offset which should be accounted for.
|
||
If you need prescription lenses of a strength that are not included in the standard package, prescription lenses with sun protection or any other custom made lenses, please contact Tobii sales for a quote.

5.2.1 About the software
|
||
This is where you access information about Tobii Glasses Controller Software such as the version number.
|
||
5.2.2 Studies (Create or switch study)
|
||
This is where you manage your active studies. From here you can create, delete and switch between studies.
|
||
5.2.3 Dashboard
|
||
The Dashboard is where you start, pause and stop recordings, and where you get an overview of what is going on right now. The Dashboard consists of Glasses Control Panels, one for each Recording Unit currently or previously connected to Glasses Controller Software. Each Glasses Control Panel provides information about whether or not there is a connection between Controller Software and the Recording Unit. When there is a connection, the Glasses Control Panel provides buttons to control the Recording Unit, information about remaining battery power and SD memory card storage capacity. The Dashboard is independent of the opened study.
|
||
The Dashboard synchronizes data from the Tobii Glasses Recording Unit only when there is a connection between the Recording Unit and Tobii Glasses Controller Software.
|
||
5.2.4 Live Viewer
|
||
Live Viewer allows you to view real-time eye tracking data overlaid on the scene camera video while you make a recording. It also provides buttons to stop and pause a recording, a volume button and slider to control the level of live audio from the Tobii Pro Glasses 2 Head Unit which is heard. Critical information is also displayed here; such as remaining battery, memory time and recording duration. The Live Viewer only works when the Recording Unit is connected to Glasses Controller Software (over WLAN or by wired connection). For best performance use a wired connection.
|
||
It is also possible to log events during recording. These are then visible on the time line during replay, which makes it easy to find interesting points in the recording.
|
||
5.2.5 Recording List
|
||
Recordings List is a searchable and sortable list about completed recordings in the currently open study. Individual recordings can be replayed and exported as a gaze replay video from the recordings list.
|
||
No video or eye tracking data is stored on the tablet running Tobii Glasses Controller Software. Data is instead stored on the SD memory card inside the recording unit. This means that for any replay to work, the recording unit, complete with the SD memory card that was used for recording, must be connected to Tobii Glasses Controller Software. For best performance use a wired connection. By creating a folder on a local storage device you can copy/move recordings from the SD memory card to the local storage device and then playback the recordings from there.

|
||
No eyes detected — The Tobii Pro Glasses 2 cannot detect any eyes with any of the Eye Tracking Cameras. Move the Tobii Pro Glasses 2 Head Unit closer to the participants eye’s or change the Nose Pad.
|
||
Pupils detected, but not in range — The Tobii Pro Glasses 2 can detect pupils, but they too far away from the Eye Tracking Cameras. Move the Tobii Pro Glasses 2 Head Unit closer to the participants eye’s or change the Nose Pad.
|
||
Pupils detected, bad distance and on the limit of the field of view of the eye cameras — The Tobii Pro Glasses 2 can detect the participants pupil’s, however they are only just within the field of view of the Tobii Pro Glasses 2 Head Units Eye Tracking Cameras and are too far away. Move the Tobii Glasses Head Unit closer to the participants eye’s or change the Nose Pad. Pupils detected, OK distance and within the field of view of the eye cameras — The Tobii Pro Glasses 2 can detect the participants pupils, they are on the limit of the recommended field of view for the Tobii Pro Glasses 2 Head Units Eye Cameras. Recording should be possible with this status, however we recommend that you try and achieve a better status if possible. You can achieve a better track status by moving the Tobii Glasses Head Unit closer to the participants eye’s or changing the Nose Pad.

7.12.2 Tobii Pro Glasses 2 data structure
|
||
|
||
Data from a Tobii Pro 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).

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.

8 Advanced Use with Multiple Units
|
||
In most research scenarios one tablet/computer connects to one Tobii Pro 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:
|
||
n 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.
|
||
n The bandwidth may be insufficient to allow for several instances of Tobii Glasses Controller Software to allow live viewing of an ongoing recording.

||
11.6 Other limitations and considerations
|
||
11.6.1 Intended use
|
||
Tobii Pro 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 manual. Please read the user manual and other supplied documentation thoroughly before using the product.
|
||
11.6.2 SD memory cards
|
||
SD memory cards used in the 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.
|
||
11.6.3 Multiple connections between the controller software and the recording unit
|
||
Under no circumstances should the tablet or computer running the controller software connect to the same recording unit using both a wireless and a wired connection at the same time.
|
||
11.6.4 Eye movement classification
|
||
Gaze presented in Live Viewer and replay tabs of the 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 the controller software. When data is transferred to Tobii Pro Lab, 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.
|
||
11.6.5 Sampling rate
|
||
A 100 Hz eye tracker will eye track on a smaller viewing area than the equivalent 50 Hz eye tracker. For extreme viewing angles, the user might get 50 Hz data from a 100 Hz eye tracker.
|
||
11.6.6 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.

|
||
|
||
11.6.7 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.
|
||
11.6.8 Droopy eyelids
|
||
Droopy eyelids or otherwise obstructive eyelids can block the view of the participant’s pupils. In rare cases, such eye- lids may completely block the view of the participant’s pupils, making eye tracking impossible.
|
||
11.6.9 Eye glasses and contact lenses
|
||
Tobii Pro Glasses 2 is not designed to work in conjunction with standard eye glasses. Participants who wear eye glasses might still be included in the study by using Tobii Pro’s optional Prescription Lenses. By attaching correction lenses of a suitable strength, the participant can wear Glasses 2 and still have a corrected vision. For more information, read Prescription Lenses.
|
||
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.
|
||
11.6.10WLAN 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 the controller software or even disconnect the recording unit from the tablet/ computer.
|
||
11.6.11Power
|
||
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. The Recording unit is intended to be supplied power by a UL Listed Adapter rated 5V, 2A min.

Appendix B Correction Lenses
|
||
B1 Correction Lenses package
|
||
Correction Lenses (optional accessory) consists of:
|
||
n Correction lenses, 34 pcs., ranging from -5,0 dpt. to +3.0 dpt., in increments of 0.5 dpt. made of hard coated plastic.
|
||
n Magnetic lens attachment adapter, 2 pcs. (one spare). n Vision testing card. n Quick Start Guide (this document). n Cleaning cloth. n Carrying case with custom foam insert and storage compartment for the participant’s own
|
||
glasses. Prescription Lenses can be ordered from your sales representative or from Tobii Pro Sales. The lenses included in the package offer spherical correction only. If you require lenses that offer cylindrical or other correction, diopters outside of the offered range or refractive lenses with sun protection, please contact the sales team at Tobii Pro for a quote.
|
||
B2 Who should use Correction Lenses?
|
||
The Prescription Lenses package contains corrective snap-on lenses for Pro Glasses 2 to facilitate studies involving subjects with either short- or long-sightedness. The lenses range from -5 to +3 diopters in 0.5 diopter steps in order to provide support for participants with vision impairments. Separate lenses are provided for the left and right eyes so you can accommodate differences between the participant' eyes. If the subject only require correction on one side, the kit contains two zero strength lenses. The lenses are magnetically fitted on the head unit via an adapter, for easy fitting and removing. The lenses are attached securely enough for test situations that involve a lot of natural movement, such as in sports research scenarios.
|
||
B3 Preparing the head unit for correction lenses
|
||
To be able to fit the correction lenses onto the head unit you must remove the protective lens mounted on the head unit and then mount the magnetic lens attachment adapter.
|
||
1. Locate the small hook that keeps the lens in place, located between the scene camera and the nose pad at the front of the head unit.
|
||
2. Push the hook slightly downwards while gently pulling the lens past the retaining clip. 3. Find the correction glass mounting adapter in the Prescription Lenses carrying bag. Place
|
||
the adapter’s bottom slot onto the hook above the nose pad and fold the adapter upwards into place and finally press lightly on the two top hooks of the adapter so the adapter snaps into place.

Make sure to attach the head strap to the head unit before using it with the prescription lenses accessory!
|
||
B4 Finding the correct correction values
|
||
If the participant is wearing ordinary glasses, explain for him/her that the Tobii Pro Glasses 2 head unit, as it is not possible to wear over normal glasses, can be equipped with correction lenses to make it possible for him/her to participate in the study. As Prescription Lenses only contain correction lenses for either short-sightedness or long-sightedness, not bi-focal or progressive lenses, you can not correct both impairments at once. If the participant have glasses with both corrections, you should only correct for short-sightedness. Follow the procedure below to find out the suitable prescription lens strength for the participant.
|
||
1. Start by asking the participant if he/she knows what type of correction and the value of correction he/she needs. Short- sightedness is indicated by negative values and long-sightedness by positive values. As mentioned above, if the participant states that he/she has both types of correction, follow just the procedure for short-sightedness.
|
||
2. Ask the participant to take off his/her glasses and offer to keep them in the storage compartment in the carrying case.
|
||
If the participant know his/her correction values
|
||
a. Mount the corresponding correction lenses on the adapter by holding the lens against the adapter and aligning the hole in the lens with the guide pin on the adapter. The lens will attach itself magnetically onto the adapter.
|
||
|
||
a. Hold up the vision testing card at the distance at which the viewing of the targets in the study will take place and make sure the participant can read the letters on the row corresponding to that distance. The lens strengths are only supplied in increments of 0.5
|
||

|
||
|
||
dpt.; if the participant requires a 0.25 increment (i.e. a x.25 or x.75 dpt value), it is better to use the closest lower value, as a higher value might cause some discomfort. Under normal circumstances the slighter lower value should hardly be noticeably for these applications.
|
||
b. If the participant only need correction on one eye, mount the lens with zero strength on the opposite side.
|
||
If the participant does not know his/her correction values
|
||
a. Ask the participant if he/she needs the glasses to see well on longer distances or on both longer and shorter distances. If so, use correction lenses with negative values. If the participant says he/she need glasses to see well on short distances, i.e to read, then use correction lenses with positive values.
|
||
b. Mount a correction lens with a value of +/-1 (depending on the answer above) on the right side of the head unit by holding the correction lens against the adapter and aligning the hole on the lens with the guide pin on the adapter. The lens will attach itself magnetically onto the adapter. Ask the participant to cover his/her left eye. Hold up the vision testing card at the distance at which the viewing of the targets in the study will take place and make sure the participant can read the letters on the row corresponding to the distance.
|
||
c. If the participant can read the text at the stated distance, then proceed to check the left side by repeating the above process, this time with the right side covered. If the participant has trouble reading the text, change the correction lens to the next higher value and repeat. The lens strengths are only supplied in increments of 0.5 dpt.; if the participant requires a 0.25 increment (i.e. a x.25 or x.75 dpt value), it is better to use the closest lower value, as a higher value might cause some discomfort. Under normal circumstances the slighter lower value should hardly be noticeably for these applications.
|
||
d. After finding the two correction values, check the participant’s sight with both eyes open. If the participant experience some discomfort, attach correction lenses with the closest lower values, and try again.
|
||
e. If the participant only need correction on one eye, mount the lens with zero strength on the opposite side. Be careful to always replace the lenses into the correct slot in the carrying case to avoid mixing them up.
|
||
1. Now the participant should have a working sight correction and you are ready to proceed with the study.
|
||
B5 Removing the correction lenses and the lens attachment adapter
|
||
To remove the correction lenses and the lens attachment adapter, use the following procedure:
|
||
|
||
Tobii Pro Glasses 2 User Manual v2.0.2
|
||
|
||
63
|
||
|
||
1. Remove the first correction lens by gently pulling it straight out.
|
||
1. Check the lens and gently wipe it clean with a cleaning cloth if necessary. 2. Make sure to replace the lens in the correct storage slot to avoid confusion in the future. A
|
||
good idea is to only have one lens per side removed from the carrying case at a time. 3. Repeat step 1 to 3 for the other lens.
|
||
4. To remove the lens attachment adapter, lift the two top hooks off the head unit and gently pull the adapter upwards to remove it.
|
||
1. Place the adapter in its storage compartment. 2. Mount the protective lens by hooking the top part of it in the small holes up top and then
|
||
gently pushing it into place. 3. (Optional) Remove the head strap from the head unit.

Appendix C Sync port
|
||
The recording unit is equipped with a sync port capable of transmitting and receiving a sync signal to and from external devices.
|
||
The sync port is a standard 3.5 mm jack where the tip is used for receiving a sync signal, the middle ring is used for transmitting the sync signal, and the sleeve, which is ground.
|
||
C1 Sync-out
|
||
Sync-out is emitted from the recording unit using a standard TTL 3.3 V signal, described as a high signal (1 (one)), or a low signal (0 (zero)).
|
||
Implementation
|
||
n The sync signal, which is 10 000 ms long, starts when the recording starts, and is initiated by a start sequence in the following format: One 500 ms long high pulse, (3.3 V), followed by a 500 ms long zero pulse (0 V), repeated three (3) times.
|
||
n During the recording the sync pulse is emitted once every ten seconds with a duration of 1000 ms, followed by a 9000 ms long zero pulse, and so on.
|
||
n When the recording is terminated, the sync pulse stops immediately. No stop sequence is transmitted.
|
||
n If the recording is paused, the recording unit immediately stops sending the synchronization signal. When the recording then resumes the recording unit transmits a resume signal, similar to the start signal except that it consists of only two 500 ms pulses instead of three.
