Visual Presentation Challenges for Mobile Spatial Applications: Three Case Studies

Using mobile devices for exploring and interacting with the user´s physical environment is among the most promising candidates for commercially successful future telecommunication services and applications. This trend is confirmed by the rollout of latest mobile phones equipped with advanced navigation features like built-in GPS receivers, digital compasses and acceleration sensors. The increasing technological potential of mobile spatial interaction (MSI), however, requires a wider comprehension of appropriate visualization possibilities for spatially referenced content in the field of mobile human-computer interaction. In this paper, we argue for an integrated approach comprising innovations in MSI with latest advances in visualization. In order to demonstrate the potential of this joint approach, we present a series of three related projects and highlight in each case research challenges and results in the field of mobile HCI and mobile appli-cation development as well as corresponding advances of the underlying server-side rendering algorithms.
