Abstract

Today’s mobile phones are increasingly used as mediators between the real world and georeferenced digital information. However, common 2D maps as the most often applied visualization method are bearing inherent limitations when presenting a vast amount of data on a small screen. Therefore, in this paper, we propose ‘ambient tag clouds’ as an abstract alternative visualization approach for spatial information. Ambient tag clouds are designed as an extension of their Web counterparts exploiting the context-awareness of mobile devices. In our prototype implementation this novel concept has been combined with a gesture-based interaction method and thus enables mobile users to scan their current surroundings and make summarizing snapshots of adjacent areas.
