We also (here at GW) work in this area, and more specifically in the use of large numbers of vibrational devices for different types of cues. Virtual contect and augmented cognition are the areas we are focusing on. You can get some links and references if you take a look at www.vibrotactile.org. I'd be interested in talking to you more on this, if you like. -Rob Lindeman > The subject line should be read, "zero Gee nav", as in navigation in a > zero gravity virtual environment.
