In this paper we present a collection of user-interface design patterns formobile applications. The patterns in the collection are grouped into a set of problemareas that are further grouped into three main problem areas. After presenting thisproblem structure we present one of the patterns in some detail. Then, we presentsome relevant findings from a validation of the patterns collection. This validationshows that both the patterns collection and the individual patterns are relevant anduseful for usability professionals with a mixed background. Finally, we discuss prosand cons of using a patterns format for documenting design knowledge, relatedwork, and future research.
