This is my second headtracking test. Now I pass the results of my 2-marker tracking algorithm to an OpenGL virtual environment test program, which uses that date to calculate my head's position in 3D space. This calculated head position, is then used as a viewpoint for the virtual environment. Being able to watch the 3D environment from different angles, by natural motions of ones head, gives a higher level of immersion in the virtual world. The code for this experiment is available for GNU/Linux on my subversion repository: svn://nuclear.dnsalias.com/pub/compvis/cam_test (camera tracking program) svn://nuclear.dnsalias.com/pub/compvis/vr_test (3D environment test program) svn://nuclear.dnsalias.com/pub/libwcam (v4l webcam library)

Headtracking 3d desktop with Compiz, second video. First clip is a simple desktop with a transparent cube to see the classic effect of the 3d box. Second clip is while rotating the cube, so you can see how the transformation is always applied. Third clip is showing some regular windows, stacked three-dimensionally by the plugin, giving regular work the same feel. You can literally look around windows. Recording was done with a Canon PowerShot S5iS hybrid digital, which does some surprisingly nice video. The netbook is a Dell Mini 9 with the 1.3MP camera - no extra hardware whatsoever was used to record this, just me, my netbook, and Compiz. The OpenCV backend used here is the SVN snapshot as of January 31st, 2009, which had a few issues I had to workaround myself (more just compilation issues). The tracking is still a bit dodgy, but we're (I'm) working on it. Today I committed some depth-perception which also made the configuration values much more sane (instead of entering 6 in a box that could range from 1-1000 due to other tracking methods, you'd enter something like 200-300). Probably won't get a video of that because it doesn't add much (especially not when the depth method is so poor that we don't get smooth transitions). So, that's it for today. Headtracking is going to be ported to Compiz++ at this point, so no more extra work on it until that's done.
