I got my Track IR Pro clip yesterday and spent the day testing things out.
Don't bother with freetrack (not supported by devs for a few years now, causes game crashing and has less functionality than the alternatives (although it has a cool skull thing that shows your head movements when you're setting it up)). Get FacetracknoIR instead and select the point tracking module (which is IR) and it works fantastically. --- There is an option to use Webcam only to track your face - it works better than I thought but I didn't spend long with it.
PS2 eyetoy works decently without modifications -
at night or a dark set up perhaps.
PS3 eye (watch out, there are 2 versions and SLEH-00201 is the one needed to be able to
remove the built in IR filter) works even better and is set it to 75fps at the same resolution (vs 30 on ps2 eyetoy) - no issues with daylight IR interference - I used floppydisc material to block normal light.
It's fucking sweet for flying games and great for racing games. Been meaning to get into ARMA 3, might get around to it now.
Takes a little while to remember not to look around so much when going fast (you'll crash in SC) but otherwise, so good, not much adjustment at all.
When racing I set deadzones so I can move my head some more while still being able to judge speed well. Can adjust the curves pretty easily, disable axis etc Very nice.
Space games, it's a must. Look around while still being in control, understand the situation you are in, or where you should go - much better.
£3 for the Sony eye (ps3) from C-E-X
£35 for the trackir pro clip, got mine from ebay - you can make your own IR source to wear if you prefer.
