Open-source head tracking software that translates real-world head movements into game inputs for flight simulators and military games.
opentrack is an open-source head tracking application that captures a user's head movements and translates them into inputs for flight simulators and military video games. It solves the problem of limited or expensive head tracking solutions by providing a free, customizable alternative that works with a wide variety of hardware and games. The software enables immersive gameplay by allowing players to look around virtual cockpits and environments using natural head motions.
Flight simulation enthusiasts, military game players, and developers interested in motion-controlled gaming who want an affordable and flexible head tracking solution. It's particularly valuable for users of games like Microsoft Flight Simulator, IL-2 Sturmovik, and other titles that support head tracking input.
Developers choose opentrack because it's a mature, open-source alternative to proprietary head tracking solutions with extensive hardware compatibility and no licensing costs. Its modular architecture allows for custom input and output modules, and its active community provides ongoing support and development.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Supports over a dozen input devices from Oculus Rift and Tobii eye trackers to webcams with AI-based pose estimation, as detailed in the tracking input list.
Runs on Windows, Linux, and partially on OSX, with truly portable USB installations allowing use without system installs, enhancing accessibility.
Includes the Alpha Spectrum filter for smoothing and shaping tracking data, with a dedicated tuning guide to improve accuracy in simulations.
Outputs to multiple protocols like SimConnect for Microsoft Flight Simulator and FreeTrack for older games, covering a wide range of flight and military titles.
The README explicitly states that OSX compatibility is currently unmaintained, making it unreliable for Apple users.
Requires consulting wiki guides for configuration and calibration, which can be daunting for new users without technical expertise.
Key features like the Oculus Rift tracker and SimConnect output are Windows-only, reducing functionality on Linux and macOS.
