I'm starting to take an interest in virtual reality gear -- head mounted displays, head trackers, data gloves, etc. More specifically, I'm thinking about possible ways you might program for it, especially in the context of Ensmer. I've done some cursory research on google, just an hour or so's web browsing. I've got a vague idea of what is available, based slightly on third rate Sci-fi novels, and slightly on this research. The first thing I found out is I am WAY TOO BROKE to afford any of this stuff right now. ;-) I've found the following site to be quite interesting: http://virtualreality.physiol.ox.ac.uk/ (makes me wish I'd applied at Oxford). It provides some hints and tips on setting up a PC for use as a VR machine, but for the most part, it sounds like a PC can barely handle it. They mention that they use Linux for their PC work. I find this difficult to understand, since I would assume most VR equipment requires a weird-ass device driver, and I don't know how many Linux hackers are reverse engineering this stuff; its not exactly standard equipment yet. Even the gaem systems don't use it yet. Well actually, you can connect these head-mounted displays to an X-box if you want... Anyway, I was wondering if anybody out there has any experience with or knowledge about VR equipment, especially as used under Linux. And how it can be coded with OpenGL... Dusty
