The Missing Link

Next Step in the Evolution of Eye Tracking and Biometrics

• Tobii Pro Glasses 2 has set new standards in the field of mobile eye tracking.
• The varioport recorder system is an established standard device in the scientific world for

  biometric data acquisition.

• The Biometric Software Suite was designed to integrate data from eye tracking and biometric

  devices to analyze data from both worlds.

So let’s put all this together:

Glasses2Varioport is the link between the Glasses 2 trigger port and the varioport recording system. Together with the synchronized import function of the Biometric Software Suite, it provides a plug-and-play solution for combining mobile eye tracking and biometric data recording.

How does it work?

Picture of biometric sensors

• Tobii Pro Glasses 2 sends trigger signals every 10 seconds via a built-in port.

• The start of a recording sequence is marked by three short pulses.

• Glasses2Varioport connects the trigger port of Tobii Pro Glasses 2 to an input channel of the varioport recorder,

  so all triggers are recorded together with the biometric data.

• The synchronized import wizard of the Biometric Software Suite automatically detects triggers in both the eye-tracking and biometric data and merges the datasets for further analysis, for example with Biometric Software Suite Professional, which includes GSR analysis, FFT filtering, other operations, and raw-data export for individual analysis in R or SPSS.

What are the advantages compared with streaming solutions on the market?

• Each data stream is recorded by its own device and at its own sampling rate. No data are lost during recording.
• Data are synchronized via a hardware link. No delay from buffering or hardware drivers is involved.
• All data are recorded on SD cards in the devices. There is no need to stream data via Wi-Fi or Bluetooth.

Which kinds of biometric data are supported?

The Varioport system supports the recording of skin conductance (GSR), ECG/heart rate, respiration, and EEG with up to 8 channels. Other signals may be included on request.

Are other devices supported?

• The system is designed and optimized for the combination of Tobii Pro Glasses 2 and the varioport or varioLAB recorder.

• Glasses2Varioport is the first solution that synchronizes Tobii Pro Glasses 2 directly with other sensors using hardware synchronization.

Are there any references?

Yes. The German Heart Center Berlin is one of our references. It is a specialized hospital for the diagnosis and treatment of cardiovascular diseases. It uses Glasses2Varioport and supports us with its expertise.
