It’s probably safe to say that most people these days have a webcam. All new notebook and laptop PCs these days seem to be equipped with them, PC companies give them away with new PCs… Even if they don’t, a reasonable quality unit can be picked up for under €20 from your nearest electronics store or supermarket.
The question is, were you aware that you can use one as a low-cost and less equipment-heavy alternative to head tracking tools such as TrackIR? FaceTrackNoIR is, as the name suggests, a head tracking tool that requires no hardware additional to your webcam, no hat or silver spots, no clip. Just your face and some software which, if you find it useful, you should probably consider donating to its development and upkeep. It’s easy to set up and free to download, supporting over 100 titles including most of the major flight sims. Take a look at the developers’ website and try it for yourself!
