Aplicação de um modelo de navegação de IHM ao contexto de sistemas industriais.

Abstract

This work presents and discusses the application of a navigation model to support the analysis of computer-user interfaces. This model, built in Colored Petri Nets (CPN), presents a generic structure conceived in order to support the usability evaluation of the user interfaces navigation component. The application context is that of supervisory control systems for industrial plants. The study was developed in two phases. In the first phase, a model originally proposed in [40, 41], was used to represent an industrial plant, having been adjusted to this new context. In the second phase, the model was extended to represent the temporal behavior of the navigation component in order to represent actions with temporal restrictions such as alarm treatment. Do trabalho conclui-se que o modelo de navegação adotado se adequou aos propósitos do estudo e ao contexto da interface de sistemas industriais. Conclui-se também que a utilização deste modelo é valiosa na análise da usabilidade de sistemas, do ponto de vista da navegação. From this work it was concluded that the navigation model, is adequate for the navigation analysis as well as to the industrial context, and that the proposed extension made feasible the representation of the industrial system's interface behavior. It was also concluded that the use of the model approach is valuable in the analysis of the usability of these systems, from the viewpoint of navigation.
