Abstract

AT&T Communicator is a speech-enabled telephony-based application that allows the end-user to select and reserve airline itineraries. We report the results of an experiment exploring how the amount and structure of information presented in complex lists influences the user experience and the ability of subjects to complete an itinerary selection task. Presenting all the relevant information needed for a decision at once was the factor that most positively influenced successful task completion and the user experience.
