OpenTracker

OpenTrack is a free, open-source software application designed to provide head tracking for sim racing, flight simulators, and other immersive titles.

OpenTrack uses a wide array of input devices like webcams, IR LEDs, smartphone sensors, and even dedicated eye trackers. Its main purpose is to translate real-world head movements into in-game camera or viewpoint adjustments, giving a natural sense of spatial awareness without physically turning the monitor.

It provides alternative input to hardware-based systems like TrackIR and supports various tracking inputs, such as AI-powered neural networks and Aruco markers.  

With OpenTrack, users can:

• Connect different types of tracking hardware (including AI-based trackers like AITrack, Beam, or neural net vision models), or even common webcams.

• Customize profiles with filtering, output shaping, and dead zone adjustments for each supported game.

• Output to industry-standard protocols like FreeTrack and TrackIR, which are natively supported by hundreds of simulation and racing games.

OpenTrack is regarded highly for its flexibility, wide compatibility (over 200 games), and active development, making it a popular and cost-effective alternative to proprietary tracking solutions for enhanced immersion in sim racing and cockpit-based games.

AITrack is a free, AI-powered head tracking software that allows users to achieve head movement tracking in racing simulations, flight sims, and similar games using only a webcam, no special hardware is required. The software uses computer vision to track your face and head position, then transmits this data to OpenTrack or similar programs via UDP, turning head movements into camera/view changes in compatible games.

Key features of AITrack include:

• Works with standard webcams, making it accessible and hardware-less compared to solutions like TrackIR.

• Tracks six degrees of freedom (6DoF), meaning it can interpret movements up/down, left/right, and rotation, for immersive cockpit control.

• The setup is simple: install AITrack, point the webcam at your face, and connect it to OpenTrack for game integration.

• Because it depends on machine vision, performance will vary with webcam quality and lighting, and may require occasional calibration for smoothness.

AITrack is widely used for free and accessible head tracking in sim racing, offering a strong alternative to expensive hardware trackers.
