Public transport maps are typically designed in a way to support route finding tasks for passengers, while they also provide an overview about stations, metro lines, and city-specific attractions. Most of those maps are designed as a static representation, maybe placed in a metro station or printed in a travel guide. In this paper, we describe a dynamic, interactive public transport map visualization enhanced by additional views for the dynamic passenger data on different levels of temporal granularity. Moreover, we also allow extra statistical information in form of density plots, calendar-based visualizations, and line graphs. All this information is linked to the contextual metro map to give a viewer insights into the relations between time points and typical routes taken by the passengers. We also integrated a graph-based view on user-selected routes, a way to interactively compare those routes, an attribute- and property-driven automatic computation of specific routes for one map as well as for all available maps in our repertoire, and finally, also the most important sights in each city are included as extra information to include in a user-selected route. We illustrate the usefulness of our interactive visualization and map navigation system by applying it to the railway system of Hamburg in Germany while also taking into account the extra passenger data. As another indication for the usefulness of the interactively enhanced metro maps we conducted a controlled user experiment with 20 participants.

Die meisten der aktuell im Allag vorfindlichen Touch-Flächen wurden unter Anwendung komplexer und kostenintensiver Technologien realisiert. Gerade für das Anwendungsszenario eines Touchfloors, bei welchem meist eine überdurchschnittlich große Touch-Fläche erwünscht ist, werden kostengünstigere Umsetzungsmöglichkeiten angestrebt. Dieses Paper dient als Ausgangsbasis für die Umsetzung eines Low-cost Touchfloors, der die kollaborative Arbeit eines Projektteams unterstützen soll. Mithilfe einer Analyse des State of the Arts der Touch-Technologien und einer anschließenden Evaluation, wird die Touch-Technologie abgeleitet, die sich am besten zur Realisierung dieses low-cost Touchfloors eignet. Aus der Evaluation geht hervor, dass vor allem optische Touch-Technologien, insbesondere visionsbasierte, für die Umsetzung von kostengünstigen großen Touch-Flächen geeignet sind.
