I am experimenting with Headtracking.
I use my old Microsoft LifeCam HD-3000 (a cheap webcam) and two programs from Github.
Only tested it today and for an hour of setting it up it’s already something I can see myself using more often once I get around to do the finetuning.
The Webcam is plug & play and the two programs need a little settings editing (see turorial). Then it’s just understanding the principles of the 6 axis and how to draw those response curves.
Result of my first attempt. I will need another afternoon to get finetuning right and find out which axis I actually find useful.

I did much the same just a few weeks ago and I am very satisfied with the results. Like you indicated, once you get the fine tuning completed you should be good to go. It makes a huge difference being able to look around the cockpit without having to fumble around with the camera controls!

Once I have some sufficient settings, I might upload my .ini file.
These are my current preliminary settings.
I sit about 80cm away from the webcam, which is on top of my 27" 16:9 Monitor.

Defo disable Roll and Z for the time being.
To test what one axis does, disable all others and find the best Mapping Curve and values and go from there.
First initial testing with an open cockpit aircraft, the Stearman.
my thoughts are that it makes sense to have different profiles for various aircaft types.
In this .ini Profile I put the Yaw ° to 180 so I can look around more.
P.S.: sorry yes I know overspeed…
I really dig it for open Cockpits
I’m using for over year now this app https://smoothtrack.app/ It works really well with open track but is draining battery as most calculation are done by phone.

Did this too about a year ago, it works really good, it’s free and no need to wear any “tags”.
Some good info here, Thanks Overkill Simulations

I have been using an Aruco system for the last few months as it’s good in low light conditions (which is essential for a 60fps webcam)

I did some further refinements to my settings for the Spitfire.
Still a WIP though.

Looks good … I think I’ll have to try AI track for myself as it’s quite embarassing answering the door with a 20cm slab of cardboard on my head 
(I even take it off when I walk near a window)

AI Track has no issues with a darkened room, btw.
I tried it with only the PC Monitor as light source and it automatically lights up the videofeed in AI Track so that the picture looks like I had all the lights in the room on.
Also, I wear glasses, no problem for AI Track.

I’m sold already … thanks 
Yeah it seems like the same tech also not too expensive, the wide apart mikes are probably good for conferencing etc. but I have no use for them.
That’s interesting. What improvements did you see with this one compared to a 30 FPS webcam ?
Still working on the settings.
Looking up is now a little better.
I wished the Lightning would not wobble without canopee and with open windows, but that’s the flight model.
I’m using the Aruco/Opentrack system too, for some time now and am happy with it. I use it with a cheap webcam. Works very smooth if you configure it right.
A 2nd big advantage i.m.h.o. is that it uses almost no CPU. I tried it with AITrack, but my CPU temp went sky high.
And yes, it looks odd with that thing on your cap, but if nobody can’t see, who cares…
Plus one smooth track user here. It works just great and I like that all calculations are done by the phone like mentioned before.
