Coming soon: Shoes that talk to you and computers that react with a wave of your hand.
The shoes are still a concept product (Mario even wonders if they might be an early April Fools' joke) and come complete with a smack-talking voice that sounds a little like KITT from "Knight Rider" and encourages you to exercise.
But the "Minority Report"-style Leap Motion controller is a real product you can pre-order now. It starts shipping in May. In some cases it can replace your mouse or keyboard to let you interact with whatever's on your screen without touching anything.
