Multidimensional evaluation of user interfaces usability enriched with decision support systems analysis

Abstract

Interactive Systems' User Interfaces can be considered as a special type of decision support system, as it exposes system's internal logic for supporting users' decision-making processes. Several evaluation methods can be used for investigating if the behaviour of a user interface complies with the best practices of human interface design. This paper investigates how Decision Support Systems methods and tools might assist in the analysis of Interactive System's User Interfaces. A research instrument is designed, as well as a multidimensional view of the data is created and presented. This work presents an alternative demarche for extending usability measurements of interactive interfaces, seeking to assist system designers and administrators in maintaining and improving their systems.
