I had the opportunity to try this cool Attachment 22885 stuff:
a FREEWARE headtracking software, that only uses a webcam, and some software that has to be installed.
Please alow me to quote from their site:
The webcam I use is an old Playstation 2 EYETOY (stole it from the kids), with windows drivers.The existing programs have proven their power and are used by many people around the world. These programs have also got a few shortcomings: they may cost you quite a bit and they require the users to wear some clip, hat or other device with LED's to make it work...
To make face-tracking available to everyone and eliminate the need for anything but your computer and a (simple) web-cam, we started making FaceTrackNoIR in May 2010 and by now, over 100 games/sims can be played with it.
New in version 1.4 is support for MS Flight Simulator 2002, 2004 and FSX, as well as support for some older games like CFS3.
Just install the program, version 1.3, then install the update 4 over that, for FS compatibility.
Check their site:
Give it a go, it's extremely easy to use, and, a DUTCH developement and implementation.
Let me know what you think of this!
