Deriving User-requirements from Human-Computer Interfaces

In this paper we explore the possibility of designing components of information systems by optimally exploiting the information explicitly or implicitly in human-computer interfaces. In this process it is assumed that the end-user, with minimal training, is able to sketch a prototype interface of the future application, from which the conceptual model of the application domain can be derived semi-automatically. In particular, the information contents of the electronic forms can be extracted and conceptualised through reverse engineering and integration techniques to significantly contribute to the conceptual schema of the future database.
