Wurz, Randy: I tested it and it's definitely a reflection coming back from my glasses. If you wear glasses try it wearing the cap clip with the software in camera mode and you'll see what I mean. It sees another reflection (a fourth dot) when you look in a certain direction (generally right back at the camera--slightly up and slightly to either side) and voila--it messes up for a sec. I cover the offending lens on my glasses and the other dot goes away. Can't really fly like that LOL! With my contacts on it's fine, but I don't wear them 24/7. Especially this time of year. My allergies have been bad and by night I'm ready to ditch the contacts to get the crud out of my eyes. The Pro clip with the LEDs in it is the answer. In that mode TrackIR uses active tracking using the LEDs on the Pro clip and looking for them rather than passive tracking looking for a reflection back from the cap clip from the LEDs on the camera. So in that mode there's nothing shining at me to reflect back at the camera. The software has a button to use either mode so it knows what to look for. I totally get how it works. Just gotta get the clip with the IR LEDs on it, that's all. Problem solved.
Del: it's not that bad. I really think I'm gonna like this once I get used to it. I'm not having any of the motion sickness or vertigo or whatever others have complained about. Years of not moving other than my thumb to look around is a habit that's gonna die hard. I'm gettin there. Gotta break the other habit of leaning in closer to the monitor when in a fight too. Almost got that one ironed out. Also the leaning in slightly to turn to look back is something that hasn't become a natural thing for me yet. But if ya think about it, if you were actually in the plane you'd have to do that to look back--so it should be. Gettin there.
Ya just gotta tweak the software to suit you and dude, it's friggin omni-adjustable. You can do whatever you want with it pretty much. You CAN actually set it 1:1 in the software if you like, but sheesh! I hope you have a good chiropractor on speed dial if you do! I'd never want to move my head that far back and forth and up and down playing AH for hours at a time like I do when I do. I can't imagine the neck pain that'd cause. On one hand, as godawful expensive as they are, I like the idea of the VR headsets but I gotta wonder what it'd do to your eyesight focusing on something that is in reality less than 6 inches from your eyeballs for hours at a time. I know it's a bit of optical trickery to produce what you're brain thinks you're actually seeing, but it is actually that close. Hell my eyes are bad enough and as I rapidly approach the 50 year mark having to use cheaters now for everything within a couple of feet is annoying the hell out of me!
