OpenTrack is a free, open-source application that bridges the gap between eye-tracking hardware, like the Beam Eye Tracker, and over 200 compatible PC games. It supports a wide range of genres including flight simulators, space simulators, combat flight simulators, racing simulators, bus simulators, farming simulators, and even some FPS and RPG games. OpenTrack seamlessly relays your head and eye movements from the Beam Eye Tracker to the game software, enhancing immersion and control.

While OpenTrack is versatile in its input methods, supporting IR-LEDs, FreePIE UDP receivers (allowing phone use as a tracking device), its compatibility with the Beam Eye Tracker makes it particularly powerful. This combination offers a cost-effective solution for adding eye-tracking capabilities to your gaming setup without the need for expensive head or eye tracking hardware.

OpenTrack's features include output shaping and filtering, ensuring smooth and accurate tracking data translation. Its regular updates and active community support make it a reliable choice for gamers seeking to enhance their experience with eye-tracking technology. As the only free, continuously updated software, OpenTrack remains a go-to solution for PC gamers looking to explore new dimensions of interaction in their favorite titles.
