I just came back from Montreal for the presentation of my master thesis and for christmas holidays. VRoot will gradually regain the same posting rate.
I went before at HP Labs, Palo Alto, to meet researchers working on the Halo Collaboration Studio. They showed me really interesting stuff and I will probably post some information about it soon. HP Labs is collaborating with us on our Next Generation Tele-Immersive Virtual Videoconferencing System here at University of Alberta. This project is mainly a collaboration between TRLabs, Advanced Man-Machine Interface Lab (University of Alberta) and HP Labs.
