Here are some pictures from SIGGRAPH 2009 in New Orleans.
Google had their tent at SIGGRAPH.
Sigh: no public transportation directions yet for RTA in New Orleans in Google Maps. Note to self: write to RTA.
There were several booths displaying virtual reality. In this showcase, actor is fitted with facial device (which show as bright colored lights on camera but are not so in real life). In this example she is channelling a mean dude. On the second floor another actress was channeling a digital rhino.
This dude from France demonstrated a cool virtual goggle that can interact with game pieces on a virtual display. Practical implications: Virtual RPG.
