About the requisites analysis to the interface project

Abstract

The fields of Information Systems (IS) and Human-Computer Interaction (HCI) have both experienced a move from an exclusively objectivist perspective to the inclusion of interpretative and subjective aspects in system design. This paper aims at constructing a semiotic-based referential to model user requirements reflecting them in the interface design. The proposed approach is illustrated with a case study in which three teams of academics with practical knowledge in software development were exposed to the methodological referential to model a real problem using methods and techniques from Organizational Semiotics. From this modelling, interface prototypes were built and we could observe that they had reflected the language, rules, navigation and spaces represented in the models. The results achieved suggest that the theoretical referential seems to be an appropriate foundation for understanding a subjective view to information systems, and a guiding concept for joining HCI and IS projects.
