There are lots solutions out there, but I assume you want to > build your own system. Yes, one of my objectives is to make it cheap and by using "normal" webcams. The real task is done - I have built a 6DOF sensor and it works, but (!) I want to make it faster. And these 80 ms are really nagging me. I am also very interested in links and projects that I can read about 3D tracking system like this in general and particularly head tracking. > > -- > ==================================================== > Tommi Ilmonen > Tel: +358-50-3841 543 > Ubiquitous Interaction Research Group > Helsinki Institute for Information Technology > http://www.hiit.fi/ubiquitousinteraction/ > ==================================================== Best regards, --David > > _______________________________________________ > pwc mailing list > [email protected] > http://lists.saillard.org/mailman/listinfo/pwc _______________________________________________ pwc mailing list [email protected] http://lists.saillard.org/mailman/listinfo/pwc
