I wandered around today and visited a few sessions as well as the expo hall. I really didn't see the utility of motion-based sensor software and other kinds of supplies for the gaming industry to me as a web developer until the evening. I went to a Dr. Dobb's session on Second Life which pretty much was a bit of marketing for this event. It was at the session that I really was exposed to what Second Life is like (dancing avatars!) and that's when I got excited about the possibilities of the metaverse.
I don't know if motion-based sensor software/hardware can be "exported" to Second Life (though I understand export works for Maya and AutoCAD) but if so, the customization possibilities are crazy. Nintendo Wii? Playstation Home? XBOX Live? Mainstream MMOGs? This is crazy stuff.
