The impact of different media on safety and usability of interactive ATC applications

This paper identifies and discusses a set of criteria relevant to assess the impact of using different media in the design of user interfaces for safetycritical systems. An evaluation of different options concerning the allocation of such media during the design of an application in the Air Traffic Control domain is shown to illustrate and clarify our approach. Particular attention is paid on how different choices in allocating tasks among air traffic controllers affect usability and safety of operators' interactions.
