Tobii Pro X3-120

Learn how to installing and use the external processing unit for Tobii Pro X3-120.

An External Processing Unit is available as an accessory (sold separately) for the Tobii Pro X3–120 Eye Tracker. The External Processing Unit is used to improve the performance of the eye tracker and to enable setups and usage scenarios that are not
possible when connecting the Pro X3–120 directly to a computer via USB. The eye tracker is connected to the USB 3 port on the External Processing Unit and an Ethernet cable is used to connect the External Processing Unit with the computer
running Tobii Studio or other supported software. When using the Pro X3–120 together with the External Processing Unit all the eye tracking related calculations and processes take place on the External Processing Unit instead of on the computer. This will improve the performance of the eye tracker and improve the eye tracking data quality. The External Processing Unit is also necessary if your computer is lacking a compatible USB 3.0 port or if the computer you intend to use does not comply with the minimum system requirements.

To connect the Pro X3–120 Eye Tracker to your computer via the external processing unit:

  1. Connect the Tobii Pro X3–120 Eye Tracker to the external processing unit, via USB.
  2. Connect the external processing unit to the computer via LAN, using the provided Ethernet cable.
  3. Plug in the external processing unit to a power source (100–240 Vac), using the suitable provided power adapter.
  4. Turn on the external processing unit by pressing the power button.
  5. Attach the eye tracker to the laptop screen or to the monitor you intend to use.
  6. Run the Tobii Pro Eye Tracker installer on your computer to configure the Tobii Pro X3–120 for your computer. Follow the configuration instructions for the Pro X3-120 for the additional steps required.
