Abstract
An information processing system for an air traffic control environment using portable media to represent information about air flights, which portable media represent information by printing, hand drawn signs and projected signs, The information processing system includes memory, a processor, and a first and a second workstation. The memory stores a database of data items relating to air flights, a number of the data items being represented on a respective portion of a portable medium corresponding to one of the air flights. Each of the workstations includes means for removably mounting the portable media in an array, a camera and a projector focused on the array. Coupled to the memory, the processor responds to a user marking by hand a sign on a first portable medium at the first workstation by causing the projector associated with the second workstation to project just the sign onto a second portable medium at the second workstation. In further response, the processor also updates the database in the memory.
