I was wandering around the show floor when I came upon this little gem. It’s a gesture-based 3D system that lets you control your dashboard GPS/radio with a wave of your finger. It’s over at the Carrozzeria booth, which is an offshoot of Pioneer . The icons that pop up float in 3D and you wave and bat at them like someone with delirium tremens to move them out of the way. It can’t be very safe for drivers.
