Tobii Pro Glasses 2
Features
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 eye tracking 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.”
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.
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.
Components
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
- Start-stop recording
- Participant management
- Recordings management
- Live view
- Replay
- Video export
- Event logging
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.
