Setups/Telemetry Open-Source head-tracking software for iRacing!

Hey all! Sharing an open-source software I built for my iRacing setup called OpenFOV. I've made it easy, free, and open source, so feel free to download and use it yourself.

I find sim-racing great for training racecraft, but I always develop "bad eye habits" from being boxed-in by my monitor's FOV. I find this to be a huge disparity between iRacing and real seat time. I could splurge for VR, but headsets are pricey and uncomfortable. They don't play well with glasses, either...

I saw a few demonstrations of hack-together tools and get a "head-tracking FOV" with a webcam to look around in-game. It was a bit annoying to set up and didn't offer much customization, but for what it was, it made a big improvement to my monitor setup.

So, (with the help of AI), I just went ahead and built an iRacing native software from scratch! I also cooked up a complete suite of customization options, so you can nerd out and really dial it in for your specific setup.

Hoping to gather some initial feedback from the community! So, if you have an old webcam lying around, dig it out, dust it off, and give this a try!

I'm physically limited to testing on my own setup, so please feel free to report any bugs or issues on the GitHub so I can get you up and running! :)

------------------

Edit: Thank you for all the feedback so far!! 😁 Today, I released v0.2.1, which addresses a lot of the feedback I received over the past 24 hours. Keep it up!

Some general tips + info:
- OpenFOV CPU-bound, so if you're struggling with lag, try to raise the program's priority on your computer! Task Manager > Right Click on OpenFOV > Go to Details > Right Click on OpenFOV > Set Priority > High (0.2.1 should have this by default!)
- If you still find lag with the fps listed on the UI (< 30fps while running), then try lowering your iRacing settings a bit to reduce the load!
- OpenFOV can only publish values to iRacing at the speed of your camera's FPS, so higher FPS webcams look smoother! (I tried interpolating more frames using velocity, but it doesn't look good!)

Feel free to message me with any issues. Happy racing!!

Here are the settings available for tuning/customization! Map your movements to the change in FOV, lock axes, etc.

Interesting you have roll as one of the axis - do you find that useful?

Is there anyway to have depth?

I went ahead and included roll axis for the sake of completion, but personally, I leave roll disabled by default...

That's a great question - technically, yes! However, in a racecar you are strapped down to the seat, so I figured there's not much need for forward/backward movement anyways

Thanks, makes sense.

I wondered if depth would aid in immersion & make the game feel more 3 dimensional. Even being fixed in one place there is slight fore and aft movement of the head (during acceleration and deceleration)
