Solutions for co-registration of eye tracking and other biometric measures

Tobii Pro Lab's combined solutions provide the user with a full co-registration workflow including a synchronization method and data merge tools. Therefore, it allows users to avoid dealing with technical details of co-registration and instead focus on their research study. This robust and reliable solution is now available in Tobii Pro Lab to record and analyze eye tracking data together with other data streams from EEG and biometrics market leader companies.

Technical description

Combined solutions diagram

1. The solution in Tobii Pro Lab permits the recording of eye tracking data, while the other data streams are recorded in the partner’s software solution. In the case of screen-based experiments, Tobii Pro Lab also delivers the stimulus presentation.

2. The synchronization of the data streams is done by sending TTL events to all data streams which allow a very accurate data merge after the recording.

3. Next step is to analyse the eye tracking data in the dedicated software Tobii Pro Lab, where it is possible to run an advanced eye tracking analysis, such as fixation filters, AOIs, and event logging.

4. Starting with version 1.130, Tobii Pro Lab supports PLOF 2.0 export format, designed to contain all eye tracking and event data in a machine-friendly format that can be imported into any of our partner’s solution software. PLOF export format achieves an accurate and robust merge of not only raw eye tracking data, but more importantly of any gaze, AOI or behavioral event data generated in Tobii Pro Lab.

5. Last step is to analyse the EEG or other biometrics data with help of the merged eye tracking data. This is done in the partner software using all the specialized tools required for a correct EEG and biometrics analysis.

Who benefits from this solution?

This solution is for users who want to combine eye tracking with EEG or biometric datasets and need to merge the data for an integrated analysis. Examples of merging data may include when a researcher desires to:

  • Segment data and analyze trials according to gaze behavior, e.g., AOI visits, pupil size
  • Discard data, e.g., Reject trials when the participant was not looking at the target element or did not look at the fixation cross before the trial started
  • Run fixation related potential (FRP) analysis, an event-based EEG analysis time-locked to the fixation onset instead of to the stimulus onset in ERP analysis.
