What should it do?

One important application area for location-aware mobile devices is offering navigational support. This paper summarizes the results of preliminary user tests with different navigation interfaces designed for small screens. We focus on the effectiveness vs. likeability of the interface and explore how these two aspects can be combined to support the navigational task of the user. Our research shows, that offering rich contextual information can support the navigational task by providing the user with a feeling of familiarity and perceived credibility. At the same time it can be a source of distraction, and cause misinterpretations. We propose the use of a rotating route-model to provide the user with a navigational guidance system both effective and likeable.
