Resumo(s)
In today’s disaster management context, decision-making and information management is a
crucial aspect, given the complexity of the tasks the decision-maker has, as well as the sheer influx
of information coming in at any given time. As such there is a need to develop a system that can
aid both the decision makers in the command post but can also collect the information gathered
by the responders on the field. This system should also aid the decision maker by providing
counselling according a set of rules, giving the system an intelligent aspect. Thusly THEMIS is
born, an intelligent system to support decision making in crisis scenarios.
As any given system must have an interface, the usability and user experience are a concern, but
given the nature of crisis scenarios, this aspect of user interfaces becomes much more critical.
It is in this context that this dissertation’s goal becomes clear: design and test the interface
prototype of an emergency management intelligent system, following the User-Centered Design
framework.
With this goal in mind, the steps of the framework were followed, by beginning to understand the
user, the context of use, resulting in understanding the user’s needs. From here, the system
requirements emerged, and paper prototyping began. After validation with experts and possible
users, the interfaces were prototyped digitally for both the desktop and mobile system
applications. This was followed by usability tests, using the Cognitive Walkthrough method, the
System Usability Score and the User Experience Questionnaire. In order to complement the
testing phase, eye tracking data was gathered during the desktop version’s usability tests, which
gave further insight about user behaviour.
As such, it was concluded that prototypes scored highly both for usability and user experience,
and there was an overall improvement on the various versions of both the desktop and mobile
apps. The tests with eye tracking also allowed to identify a few issues that otherwise couldn’t be
detected, namely key items the users were missing on the interfaces.
