OpenFOV v0.1.0

Webcam head tracking for iRacing!

What this is

OpenFOV turns any ordinary webcam into a head tracker for iRacing.
It watches your face with MediaPipe, smooths the result, and feeds it to games
through the same TrackIR / NPClient interface they already support.

This is the first public release. It targets iRacing specifically, and ships
everything needed to go from installer to working in-game tracking in a few
minutes.

Highlights

  • Webcam head tracking powered by MediaPipe's 478-point face landmarker.
    Any USB or built-in webcam works.
  • iRacing out of the box. OpenFOV detects iRacing automatically and
    registers itself as a TrackIR device through a bundled NPClient surface, so
    the game's existing Options → Graphics → TrackIR toggle is all you flip.
  • First-run wizard walks you through camera pick, neutral-pose
    calibration, and game selection. You're tracking before you've read any
    docs.
  • Per-axis tuning for yaw, pitch, and roll: invert, sensitivity, and a
    full Bezier response curve editor (drag anchors, right-click presets,
    live indicator that follows your head).
  • Adaptive smoothing via a One Euro filter (low lag when you move, low
    jitter when you don't), plus median-based outlier rejection and a
    configurable dead-zone around center.
  • Named profiles save the whole tuning state — keep separate setups for
    GT3, formula cars, or different rigs, and switch from the profile bar.
  • 3D pose widget renders a small live head model so you can see exactly
    what the tracker is sending the game.
  • Configurable hotkeys with F9 recenter out of the box; rebind in
    Settings without restarting.
  • Performance presets (Performance / Balanced / Quality) tune resolution
    and inference downscale to match your CPU.
  • System tray integration: Show / Recenter / Pause / Quit. Close hides
    to tray; OpenFOV keeps running in the background.

Install

Direct download: grab OpenFOV-0.1.0-setup.exe from the
Releases page.

On first launch Windows may show "Windows protected your PC." Click
More info → Run anyway. The build is currently unsigned while our
SignPath Foundation certificate is in review; every release includes a
VirusTotal scan link for verification. Full walkthrough in
docs/INSTALL.md.

System requirements

  • Windows 10 or 11 (64-bit)
  • Any DirectShow or Media Foundation webcam
  • ~4 GB RAM, modern dual-core CPU (a quad-core is comfortable)
  • iRacing — or any game implementing the TrackIR / NPClient API

Known limitations

  • iRacing is the only validated game. The NPClient surface is generic
    and should work with other TrackIR-aware titles, but they aren't tested
    yet. Reports welcome.
  • CPU inference can dip below 60 fps under heavy GPU load on lower-end
    CPUs. Switch to the Performance preset if you see stutter.
  • Unsigned binaries trigger SmartScreen until our code-signing
    certificate clears. See the install walkthrough.
  • No multi-monitor FOV expansion in this release — output is pose only.
  • Lighting matters: tracking quality drops in very dim or strongly
    back-lit scenes.
