Development of a Graphical User Interface Prototype for an Ambulance Dispatchment Simulator

Abstract: This paper is based on Amouzad Mahdiraji’s research about an agent-based ambulance dispatchment simulator. A simulator which is currently not focused on visual user interfaces and usability. In this study, we implemented design science to structure our research for creating a user-friendly Graphical User Interface (GUI) prototype for an ambulance dispatchment system. We used theories concerning usability and human cognition to support the development of the prototype which was later evaluated through interviews. Cognitive overload or confusion concerning a GUI can cause stress and problems which results in various errors and costs, affecting businesses and users in multiple ways. Our study resulted in a second version of the prototype in which interview analysis and theories, mainly the Gestalt principles and heuristics, were applied. Design decisions for the second version were made to improve the usability and minimize risks of confusion. Usability in a graphical user interface can be achieved in different approaches, this study shows one of them. However, to create a suitable interface for an ambulance dispatchment system, more research is required.
