Gestão do conhecimento no processo de concepção de IHC e uma nova abordagem para a obtenção de uma especificação conceitual da interação.

Abstract

The main objective of a human-computer interface’s designer should be to produce an interface that turns the system easy to learn, easy to understand and easy to use. To reach it, the designer needs to have in your hands, in some way, knowledge of the most varied natures, such as, knowledge about the tasks, the sceneries, the user's characteristics and abilities and the best forms of accomplishment of the tasks, besides the specific knowledge of Computer Science for the project and development of interactive systems. In the context of interface design not just the natures but the sources of the knowledge are also quite different: people, project guides, ergonomics norms and patterns and reports of project experiences. The valorization and the efficient exploration of the knowledge involved in the process of interface design depends essentially of definition and adoption of methods that allow to classify, to represent and to integrate and to use those knowledge. When the current methodologies used in interface design treat the knowledge classification and the knowledge representation make it by the absence of any explicit strategy of Knowledge Management (KM). To facilitate the designers' preparation for an appropriate practice of KM and to minimize their cognitive effort was defined a specific methodology. In this methodology were defined methods to classify, to represent and to integrate and to use the important knowledge of that context. In addition to the preparation methodology a new approach was proposed for the process of obtaining an interaction’s conceptual specification starting from the description of the task. In that approach a new model was proposed based on the representation method adopted and in a scenic metaphor. The validation of the new approach was accomplished by the production of interfaces for web tutorials and interactive systems.
