TrackBridge: Head Tracking

Turn your iPhone into a precise head tracker for flight, racing, and truck sims - no extra hardware, no TrackIR, no account. Move your head, and the in-game camera follows.

TrackBridge uses your iPhone's TrueDepth camera to capture your head's rotation and position, then streams it over your local network to OpenTrack on your PC. From there it drives head look in the sims you already play.

HOW IT WORKS
Your iPhone reads your head pose (yaw, pitch, roll and position) and sends it via UDP to OpenTrack. OpenTrack passes it on to your game - the same setup people use with dedicated tracking hardware, just with the phone you already own.

QUICK SETUP
1. Install OpenTrack on your PC (free, open source).
2. In OpenTrack, set Input to "UDP over network".
3. Open TrackBridge and enter your PC's IP address (default port 4242).
4. Place your phone facing you - on a stand, a mount, or against your monitor.
5. Start tracking and look around in your sim.
An in-app guide walks you through it the first time.
