One of the great things about spending time at KEI is to experience what all the other entrepreneurs are doing. My colleague and office-mate Philippe Bossut has been working on hands free interfaces to virtual worlds like Second Life, using a new breed of 3D cameras. The Creative group here made an exciting video of the progress so far.
Having tried some of the earlier versions, I can say that it feels very natural, once you get used to it. In years to come, this kind of interface may become as common as the keyboard and mouse are today.
