I'm sure you must have not forgotten how Tom Cruise manipulated documents and the likes in the movie Minority Report. Well if you want a similar experience, you won't need to head over to a sci-fi movie set, but instead head over to your gaming console because very soon a system will be out that will allow you to control characters by simply moving your hands. The Zcam device uses a small 3D camera which sits below the computer screen and uses infrared to track people's movement. The device was showcased at the CES and the Israeli firm that has developed the system claim that the technology could revolutionize the way people interact with computers.

The Zcam device is expected to go on sale later this year and will cost around £100 ($198) with a game.
