They delivered their TouchTable to the 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 to easily change a view from miles above the Earth to a detailed layout of a single city block."
