The MIT Media Lab’s G-Speak Interface

I have been following this for a while and it's interesting to see the developments in this tech over the past few months.

Its tough to see though how this could be intergrated into a possible mouse beating interface system, while the user has to don gloves to interact with it, although they did mention that multiple users would be accepted. 

This is a Techcrunch interview with the current developers of the G speak system, i think some of these gestures will need to remain application specific though, for example, it would be nice to rotate the ERF project on its single axis rather than simply zooming through it.
