Download, install, and open the free OpenTrack PC software

Download the free OpenTrack PC software (or find the latest releases here). The link provides the most recent OpenTrack release. Scroll down to the assets area and download the .exe file. Install OpenTrack and open the software to begin the configuration steps.


Start with a new and empty configuration file in OpenTrack

If you’ve previously set up OpenTrack, please begin with a new empty config file to ensure compatibility with Beam. If Beam feels different post-update, follow these steps: Open OpenTrack, stop tracking, click Profile, choose Create new empty config, name it, and save.


Assign a keyboard shortcut to the center method in OpenTrack

Go to OpenTrack, click on Options, and create a global shortcut for the Center method by clicking on Bind next to it and pressing the shortcut keys you would like to use for it. In the screenshot, we have chosen “Alt+N” to be the shortcut for the centering method.

Important: To ensure proper recentering, please position your head in the resting position and focus your gaze on the center of the screen before using the keyboard shortcut.


Change the input in OpenTrack to the Beam Eye Tracker

Click on Input and select “Eyeware Beam”. Then, click on Start to start tracking with OpenTrack. You should see the pink octopus reacting to your head and eye movements.”



Launch your game and center the head tracking

Start your game and look at the middle of your screen. Press the Center global shortcut (e.g. Alt+N) to center the in-game camera to your default position.

You don’t own a game yet that supports eye and head tracking? No problem. Many supported games offer free demos, such as Euro Truck Simulator 2

Important: Please don’t stop here. Follow the steps below to achieve smoother tracking with reduced jitteriness and to customize your range of motion.



Adjust the head and eye tracking settings in Beam

Click the Beam tray icon. Select the ⚙️ located at the top right.

In the Gaming Extensions section, under Head Tracking Output for OpenTrack, select Head & Gaze for combined tracking or Head for just head tracking.

Adjust range values to change camera responsiveness based on head or eye movements
  • Yaw means left-right and Pitch is up-down.
  • Maximum range is from -90 to +90 degrees.
  • For extended angles like 180°, modify the mapping in OpenTrack.
  • Be cautious with high eye tracking sensitivity as it can cause nausea.

Important! First adjust yaw and pitch in Beam settings. Only tweak in OpenTrack if needed for best results.


Adjust your OpenTrack settings
  • To view behind you in-game: In OpenTrack’s Mapping section, select the Yaw tab and set the maximum input to 90°. Adjust the Yaw curve for comfort.
  • Tailor the Pitch curve if needed.
  • If you notice jittering, fine-tune the Accela filter parameters by clicking the hammer icon next to Filter at the bottom right in OpenTrack’s main window.
