Capture human behavior anywhere

Tobii Pro Glasses 2 gives researchers deep and objective insights into human behavior by showing exactly what a person is looking at in real time as they move freely in any real-world setting. Understand how people interact with their environment, what catches their attention, drives their behavior, and influences decision making. Wearable and mobile eye tracking system opens up entirely new opportunities for behavioral studies.

With a unique first-person perspective and true measurement of visual attention and cognitive engagement, Pro Glasses 2 can be also used as a tool for training, skills transfer, and performance enhancement. The real-time observation of participants’ gaze data provides quick and actionable insights. Whether the eye tracking study is conducted in a lab, shopping mall, manufacturing facility, home, or sports field, you will achieve accurate and reliable results in human behavior research.

Quickly and easily analyze large volumes of the eye tracking data with the automated Real-World Mapping tool available in our Tobii Pro Lab software.

“The flexibility of Tobii Pro Glasses 2 to capture real-world data in complex natural environments is stunning and teaching us a lot about how vision really works.”

Adrian Dyer, Associate Professor, School of Media and Communication, RMIT University 

Mobility and ease of use

The user-centric design and mobility of Pro Glasses 2 have resulted in an intuitive easy-to-use eye tracking system that allows you to focus on the data analysis and makes the data collection a simple quick exercise. Any user can get started with data collection easily without prior experience with the help of the system-guided procedures and a quick one-point calibration.

The dedicated recording unit provides a more reliable solution than using third-party devices or depending on other data-processing and storage technology connected via Bluetooth. In order to ensure maximum mobility during the study, the recording unit also allows for easy access to the SD card, sync port, and batteries.

Natural gaze behavior

With Pro Glasses 2, you will be able to collect unmoderated attention data in order to observe your subject’s behavior from a first-person perspective.

The unobtrusive design with no side or bottom frames promotes maximal field of view, while capturing large gaze angles and minimizing blind areas. Participants can move their heads freely during studies due to the lightweight, sleek form factor of our wearable eye tracker. Such an unprecedented unobtrusiveness opens up opportunities for new types of studies.

Hardware variations for specific use cases

Along with the standard Tobii Pro Glasses 2, we also offer modified hardware editions. Inheriting all the functionality of the standard version, the Helmet and Integration editions allow for more flexibility and open-up additional use possibilities in the fields requiring head protection gears. Medical edition of Tobii Pro Glasses 2 expands the applications of eye tracking technology for diagnosis and training within clinical settings.

Supreme data quality

Get high-quality eye tracking data that you can rely on while running studies in real-world scenarios. Pro Glasses 2 is equipped with two cameras for each eye that use Tobii’s unique 3D eye model. This extends the advantages of our screen-based eye trackers into the domain of wearables:

  • Outstanding accuracy and precision with minimized gaze data loss
  • Successfully track a large percentage of the population regardless of eye color or shape
  • Robust pupil size estimation

The Tobii 3D eye model also ensures automatic slippage compensation and makes it possible to run eye tracking studies in dynamic environments. Even if the head unit slips slightly during the study, subjects will stay calibrated and the data quality will not be affected. The included accelerometer and gyroscope sensors allow researchers to differentiate between head and eye movements which eliminates the impact of head movements on eye tracking data. Reliable and consistent calibration is part of the automated process, and it eliminates the chances of most human error.

Pro Glasses 2 makes it possible to capture all the details of the surrounding environment by offering a full-HD scene camera with the largest field of view available on the market.

Software that supports an efficient workflow

Our solution ensures an efficient workflow throughout the entire study process, including recording and analysis. The Tobii Pro Glasses Controller software included with Pro Glasses 2 has a wireless live view function that provides full control over your study and allows for real-time observation, as well as logging behavior and events.

For deeper insights, you can export your gaze data into the Tobii Pro Lab Analyzer edition, software that enables you to analyze large volumes of data in a very cost-efficient and time-effective way. The Real-World Mapping tool integrated into Pro Lab intelligently aggregates and maps data from eye tracking videos to snapshots, so you can immediately start visualizing the quantified data or begin extracting statistics. This streamlines the logging process and dramatically reduces the time needed to analyze data recorded with Pro Glasses 2.

The Tobii Pro Glasses 2 API gives you access to all the streamed live data from Pro Glasses 2, as well as stored data for post-recording analytics. All data is accessible using this API.

Flexible synchronization options

Get more insights into human behavior by combining eye tracking with other biometric data streams. Learn what physiological responses are triggered by visual stimuli and how they are related to gaze behavior by combining eye tracking data from Pro Glasses 2 with a broad spectrum of devices, including EEG, NIRS, GSR, motion detection, respiration rate, and heart rate. To meet any specific research needs, Pro Glasses 2 supports a range of online and offline synchronization methods, like TTL, TCP/IP, and NTP.

Portability is a key feature- Pro Glasses 2 maintains the highest level of sync with very low latency without having to carry a laptop with you.


Head unit 

Eye tracking glasses capture what the subject sees and record subject comments. The head unit weighs only 45 grams, is discreet and provides maximum freedom of movement for the test participant to accommodate genuine human behavior.

Recording unit

The recording unit records eye tracking data and saves the data to an SD card. This pocket-sized unit allows the test participant to move around unrestricted.

Controller software

Control and run your Tobii Pro Glasses 2 study with easy-to-use software, optimized to run on any Windows 8 tablet or Windows 7, 8, or 10 computer. Using a tablet makes it easy to manage data collection in the field and to view the data, live as it’s happening. The Tobii Pro Glasses Controller software enables:

  • Calibration
  • Eye images video
  • Start-stop recording
  • Participant management
  • Recordings management
  • Live view
  • Replay
  • Video export
  • Event logging
  • Gaze Spot Meter
  • Switch between 50 and 100 Hz on eye cameras for 100 Hz eye trackers

Analysis software

For researchers who want to look beyond live viewing, Tobii Pro Lab provides powerful tools for post-analysis. The software is tailored to satisfy the needs of wearable eye tracking research, including aggregation, interpretation and visualization of data.
