Abstract :
The paper briefly reports on the process and design rationale for re-designing the representation of an existing emergency ambulance dispatch management status screen. The re-engineered screen was then subject to experimentation under four different categories of dispatch task difficulty. The results indicated that under the more difficult conditions, dispatch performance on the new screen improved by 40% over the performance observed by users of the old screen
