Matt writes "Northrop Grumman, best known for missile systems and other military gear, has for years been selling the TouchTable as part of what it calls an ' integrated collaboration environment.' They delivered their TouchTable to the US Federal Aviation Administration last month and will showcase their technologies next week at a defense conference in London. There are two versions of the TouchTable; one with an 84-inch screen (1600x1200 resolution), the other with a 45-inch screen (1920x1080 resolution). Moving a hand across the surface pans the display' two fingers moving apart zooms it out; and two fingers moving together zooms it in. This simple interface allows users easily to change a view from miles above the Earth to a detailed layout of a single city block."
