The vision of Pervasive and Ubiquitous Computing promises that our future environments will be furnished with an increasing number of computationally augmented artifacts. Consequently new services and applications, which will come up, should fit into the lifestyle and life-patterns of very different individuals unobtrusively. In this paper we present the designing of graphical user interfaces for end user tools in order for them to be able to configure pervasive awareness applications. These will help them keep in touch with close friends and family. A usercentered analysis was conducted, scenarios were developed and paper prototypes materialized in the form of storyboarding. The prototypes were evaluated by experts and proved that the interaction style and the metaphors used had specific constraints. Finally, conclusions based on this study were drawn.
