Tasks as agents: prototyping task models

Research has shown the significant importance of task models for the design of human-computer interfaces. However, for encouragement in real projects there is a lack of appropriate tool support for applying this modeling technique. We suggest the use of an agent based execution of task models. Agents as the underlying architecture for the execution seem to fit naturally. The transformation from tasks to agents is straightforward with respect to similarity of the concepts. This technique allows to use prototypes very early in the design process, improving the designer´s and user´s capabilities to evaluate the model
