I've been playing sim racing games for a while on my single monitor. It works, but it's not exactly the immersive experience that you'd want from a racing sim or flight simulator, for that matter. You could upgrade to a VR setup, but that's a costly proposition when you consider the cost of the VR headset and the upgrades to your PC to make sure it keeps up. So instead of scrolling through budget VR headsets and hoping my PC can handle the stress, I took the webcam I already had lying around, downloaded a free tool from GitHub, spent some time tweaking curves, and ended up with a perfectly serviceable head tracking solution for my games. A webcam can become a head tracker OpenTrack translates subtle head movements into smooth in-game camera controls without specialized hardware OpenTrack is an open-source head tracking application that takes input from a tracking source, in my case a webcam, and translates your head movements into game camera movement. The program was initially better known for its translation layer, and it was recommended to use separate trackers like AITrack to feed reliable tracking data into it if you were using webcams. However, newer versions ship with a built-in neuralnet tracker that handles webcam-based face tracking natively. You don't need an expensive webcam with IR blasters or any special tech to work with OpenTrack. Any off-the-shelf USB webcam with a reasonable resolution and frame rate (640 x 480 and 60 FPS works well for me) is good enough. You can also use your Android phone as a webcam if you don't have one lying around. Getting the tool up and running is also relatively easy. Just grab the latest version from the official OpenTrack GitHub repository, install it on your system (or extract the archive
