Tobii Pro Glasses3Wearable eye trackerEquipped with wireless real-time observation function, designed specifically for eye tracking research in real-world environments. Featuring ultra light weight and user centered design, it can obtain natural visual behavior data.

The third generation wearable eye tracking solution of Tobii Pro Glasses 3 can introduce eye tracking into a wide range of research scenarios. Tobii Pro Glasses3 provides stable tracking capability and high-precision eye tracking data, while also offering users maximum freedom of movement, ensuring the acquisition of behavior data in a natural state. The combination of Glasses3 eye tracker and ErgoLAB synchronization platform, a full range of analysis software and services, provides comprehensive solutions for various behavioral research in real environments.

2、 System features

The third generation wearable eye tracker of Tobii Pro Glasses3 is optimized for real data collection in natural conditions. We hope to create a fully functional wearable eye tracker that is suitable for any real-world research environment without sacrificing data quality and reliability.

The new features include:

●Embedding 16 infrared light sources and 4 eye tracking sensors into scratch resistant lenses to support optimal position adjustment and provide the wearer with a completely unobstructed field of view

●Adopting ultra wide angle scene camera (106 ° H: 95 °, V: 62 °)

●Additional colored or transparent infrared shielding safety lenses (MIL-PRF-32432A: 4.8.4 ballistic fragmentation protection, Class 1 SS-EN166, optical Class 1, Class F)

●The operating components are integrated into the framework, with a more rigorous design and the ability to adapt to other head equipment

●Control software supports running on Android and Windows devices

3、 Innovative achievements

*Directional eye tracking

Tobii Pro Glasses3 provides eye tracking data from various angles. The embedded design of the light source and eye tracking sensor lens enables the wearer's field of view to be unobstructed, while the ultra wide angle scene camera ensures a large range of eye tracking data collection. This means that the wearer can see more things and the system can capture more behaviors, which will bring substantial improvements to studies that require subjects to frequently observe up and down or cover most areas within the wearer's field of view.

Data Quality and Reliability

Integrating Tobii's core eye tracking technology into the lens enables the eye tracking sensor and light source to achieve optimal positioning. The combination of Tobii's patented 3D eye model and the binocular motion tracking sensor equipped on each eye can provide highly accurate eye tracking data while minimizing data loss, while also providing stable pupil size data. Slip compensation and continuous calibration techniques ensure that even if the wearer's glasses are displaced or repeatedly removed during tracking, it will not affect the stability of tracking and the consistency of eye tracking data.

The built-in accelerometer, gyroscope, and magnetometer sensors can distinguish head and eye movements, minimizing the impact of head movements on eye tracking data.

Eye tracking suitable for almost anyone

Tobii Pro Glasses3 can effectively track the vast majority of participants, regardless of eye color or shape. In addition, we provide various specifications of nose pads and corrective lenses for visually impaired subjects.

Dealing with various tests

The infrared shielding safety lens that comes with Glasses3 is used in environments that require eye protection. The use of colored lenses can conduct research in sunlight or bright environments, preventing the accuracy of eye tracking from being affected by the narrowing of the wearer's pupils due to light.

Compatible with various types of head mounted devices

The lightweight and robust design enables the eye tracker to adapt to various helmets and other protective equipment, expanding the applicability of eye tracking data collection scenarios such as factories, construction sites, sports fields, or training simulators.

5、 Software and synchronization solution

Data collection and analysis software

Using the Glasses3 Controller application, you can easily control your research process and view eye tracking data in real-time wirelessly on your Android or Windows tablet, and then export the data to the ErgoLAB platform software for analysis. The auxiliary data overlay tool can automatically and intelligently overlay eye tracking data from eye tracking videos onto static images, enabling you to efficiently obtain quantitative visualization results or extract eye tracking statistical indicators. This efficient processing method can greatly reduce the time cost of Glasses3 data analysis.

ErgoLAB data synchronization scheme

By combining eye tracking data with other physiological measurement methods through the ErgoLAB multimodal data synchronization platform, we aim to investigate physiological responses triggered by visual stimuli and examine the relationship between physiological responses and eye movement behavior. Glasses3 can be combined with a wide range of devices to synchronize multimodal data, including EEG, fNIRS, GSR, motion capture, respiratory and heart rate monitoring, etc. Glasses 3 supports a wide range of online and offline synchronization methods, such as TTL, TCP/IP, NTP, etc., and provides high data synchronization time accuracy, achieving extremely low
Hardware synchronization capability, no need to carry a heavy laptop.
