As much as I love Minority Report, even I have to admit some of the technology depiction is a bit ridiculous. Seriously, who wants to stand in front of a screen all day waving their arms and hands in tiring gestures, holding them up all day and using strange movements to get the computer to do what you want. And remember when John Anderton (Tom Cruise) went to shake someone’s hand and his files he was working with went flying across the screen with his hand movements? It’s just nuts and completely impractical.
This is a great little video pointing out the technology and UI (User Interface) elements going on.
