ABSTRACT
This chapter deals with the consequences of the widening technological opportunity for the manner in which verbal information can be conveyed. Critically, and from the systems' design point of view, the choice of presentation modality should not be determined by the available technology but rather by the impact on human performance. One such issue is faced currently by the aviation industry. Coupled with the likely increase in volume of information, new technology may impose strains on the human and affect the ability to exploit information for construction of situation awareness (SA). During the trial, participants were not provided with visual feedback as to the location of the aircraft and were asked to maintain an internal representation of the location of each aircraft, as would be the case upon contemporary flightdecks. Performance in the speech condition was not substantially different from that in either of the combined conditions.
