I can see that in 3-to-5 years we are living with computing devices very similar to those seen in the Tom Cruise film "Minority Report". I vividly recall a scene where Cruise is manipulating objects on his screen with a flick of his hand and scrolling through information with the motion of his fingers. Of course he was wearing those silly gloves... Soon, you'll be doing it without any accessories.
In fact, someone already is! Check out this video by a programmer at MIT.
I think we're closer that we think.
