User requirement analysis and interface conception for a mobile, location-based fair guide

Abstract

This paper describes the first phase of user-centred design for a mobile, location-based fair guide which is developed in the research project SAiMotion. The user requirements analysis based on a usage scenario and a formalized use case model developed in the beginning. A focus group and interviews were conducted to gain empirical insights on the potentials and probable acceptance of a location-based fair guide. Among the results of these user participation activities, are the integration and visualization of spatial data, temporal data and user-specific information as well as the support of activity planning. On this basis, an interface conception was worked out. One of it’s central parts are interactive maps. Derived principles for visual layout and interaction design of maps on small screens are presented. © Springer-Verlag Berlin Heidelberg 2002.
