We're not done with the AT&T prototypes yet. After putting our rears in the seat of a Porsche 911 and turning our questionable English into even more questionable Spanish, Ma Bell gave us a glimpse at some super rough devices fresh from the labs. The first one we got our hands on, really didn't need us to put our hands on it. ShadowPuppets sticks a webcam to a pico projector (literally... with gaffers tape) to create a touchless "multitouch" interface for your phone. Rather than have friends gather around your tiny iPhone display or force a person to awkwardly reach across you and tap on your handset, this concept lets anyone simply cast shadows to control the interface. It's not terribly dissimilar from a number of other projects out there, except it's specifically geared at turning smartphone interaction into a social experience. The demo required the assistance of an Alienware laptop, and the pinch to zoom function was a little wonky to say the least. Still, it was pretty easy to see how this might prove useful in daily life.
