This touch display can be controlled by multiple fingers by using movement and pressure to control the computer

Multi-touch driven computer

Until now, the touch screen has been limited to the uninspiring sort found at an ATM or an airport ticket kiosk--basically screens with electronic buttons that recognize one finger at a time.

Jefferson Han, a research scientist for New York University's Courant Institute of Mathematical Sciences has a touch display, by contrast, that redefines the way commands are given to a computer: It uses both movement and pressure--from multiple inputs, whether 2 fingers or 20--to convey information to the silicon brain under the display. Already, industries and companies as diverse as defense contractor Lockheed Martin, CBS News, Pixar, and unnameable government intelligence agencies have approached Han to get hold of his invention.
