Budget head tracking with SmoothTrack and OpenTrack with Microsoft Flight Simulator
If you have been wondering about trying out head tracking in Microsoft Flight Simulator, it's worth taking a look at both SmoothTrack (mobile phone all) and OpenTrack (open source windows app). Together they let your mobile phone track your face, and then transmit the direction you are looking to the simulator.
It's quite difficult to set up, but when you get it working - as I show in this video, it's quite entertaining.
