MODEL RELEASED. Virtual reality in air traffic control (ATC) systems. Scientist from the University of Washington Human Interface Technology Laboratory, Seattle, demonstrating how ATC might operate in the future. Optical fibre sensors in his black data glove & the pink-rimmed micro-laser scanner glasses connect the operator with a virtual, computer-generated, 3-D image of the airspace he is controlling. Through raising his gloved hand to touch an icon (projected image) of an approaching jet, he is placed in instant voice communication with the pilot. This photograph was taken with the cooperation of SEA/TAC international airport, Seattle.
