Controlling air traffic with touch sensitive screen

Modern air traffic control (ATC) systems are increasingly using computer generated radar displays to present targets, target information and other general information to control personnel. On the control side the radar operator uses devices such as rolling ball, joystick, keyboard or lightpen. A laboratory demonstration of a new touch sensitive control device in a simulated ATC system is described in some detail together with results. Ergonomic advantages and design problems are also discussed.
