ViewTracker

This software "was" useful until dev stopped updating this product. For now, AITrack + OpenTrack combination is track more precisely and its completely free to use on github. Do not purchase this unless you just want to throw your money away.

I really like this - I used to use TrackIR 5 Pro and loved it, but it's started having some hardware problems (i've had it a long time so not complaining about that) so I thought i'd give this a shot after the author sent me a copy. My webcam is a Logitech C920 so it's fairly decent, i'm also in a decently lit room which I also use for Streaming - so fairly well the ideal circumstances for an application like this. If you're using a dimly lit room, you're going to need a better webcam. Ideally you want a comfortable 30fps out of it at a reasonable resolution - but even a cheap webcam ought to do the job in a well lit room. The problem with dimly lit rooms is that the camera switches in to low light mode, the frame rate tanks and the image becomes quite grainy - which will likely make head tracking work considerably less well. When I installed it initially it took some time to set up and get comfortable with, it felt really twitchy and moved in unexpected ways however I have found that for my preferred games (Train Simulator 2019, Train Sim World and other sims like that) I have found that zeroing out the Roll, Y and Z mappings has made things much more stable. sure, I can't move in those directions now - but it has meant that the primary directions I want to move in are much more stable. Give the camera a good clear view of your face, it can only work with the data it has in front of it. The turning point for me was when I fired up a game and it all just started working with head tracking without me remembering to put my headset (with TrackIR) on - it felt good to have head tracking *without* having to wear that headset. I've actually switched to streaming with some small earbuds now and reserve headset usage for other times. The author also recently added Joystick output support which is quite useful in some games, I have suggested some changes to the mouse support. This tool works very well in games like Euro Truck Sim 2, American Truck Sim, Farming Sim and Train Simulator 2019. It doesnt work in games like Train Sim World because the game has no support itself - HOWEVER - using the joystick support and a custom tool that I wrote myself I was able to make it work in Train Sim World quite nicely. I have fed this info back to the author and hopefully he'll be able to accomodate the changes which should then support all UE4 games that don't directly support head tracking systems. Bottom line - you've really got nothing to lose. Get the demo, try it out, and spend the money when you're happy it works, but as I say - play about with zeroing some mappings out to eliminate movement you don't really need / want to help smooth out the movements you do want.
