Wearable eye tracking device Tobii Pro Glasses 2

Tobii Pro Glasses 2 is a wearable and ultralight (45g) eye-tracking technology to capture and analyse natural visual behaviour in real-world environments. Developed to obtain an objective data of human visual gaze, by showing exactly what a person is watching while moving freely in any real-world environment. Its great portability, maximum comfort and minimal intrusion, open an infinite range of possibilities to use it both in the laboratory and in out-of-the-lab scenarios. 

Developed with slippage compensation and an innovative 3D eye model to grant stability and minimise gaze data loss. It comes with an intuitive and powerful software platform for an easy calibration, recording and real-time visualisation. Combine this technology with other devices such as EEG or other biometrics, to obtain deeper insights into human behaviour.

Bitbrain only sells Tobii Pro eye trackers while acquiring any other compatible Bitbrain equipment.

How to use

How to use it

To record eye-tracking data, the glasses head unit must be fitted onto the test participant’s head (similar to a standard pair of glasses). After a quick and easy 1-point calibration, the researcher starts the recording from the software which is an intuitive, powerful platform to collect synchronised data in real time. Use Tobii Pro Glasses 2 with other biometric technologies for a perfect sync recording and to obtain a full vision of the participants behaviour.

  1. Preparation: Connect the HDMI cable from the Glasses to the processing unit and insert the batteries and the SD card in the recording unit. After that, press the power button until the lights turn on.
  2. Set up: Place the calibration target approximately 1 metre from the participant and press the calibrate button. 
  3. Test: Move the target side to side and ask the participant to follow it while you look at the live feed to ensure the calibration is correct.
  4. Recording: Now you are ready to record your eye tracking data and export it afterwards.
  5. Clean and storage: Clean the glasses with the chamois and store them in their own case.
