Der Beitrag stellt neue Formen des Zugangs zu den Inhalten von Bibliotheken vor. Diese wurden in Zusammenarbeit mit wissenschaftlichen und öffentlichen Bibliotheken im Rahmen zweier Forschungsinitiativen entwickelt. Zu Beginn jeder Forschungsinitiative wurden eine Reihe empirischer Studien durchgeführt, die wertvolle Erkenntnisse über die Nutzung von Bibliotheken lieferten. Diese Erkenntnisse wurden in die vier Qualitäten intuitiver, kollaborativer, transparenter und kontextueller Zugang überführt. Diese waren Ausgangspunkt für die Entwicklung mehrerer interaktiver Forschungssysteme. Die Herleitung aller vier Qualitäten der Zugänglichkeit werden erläutert und deren Umsetzung in den Forschungssystemen „Blended Shelf“, „TwisterSearch“, „Tiefenrausch“ und „Expedition“ beschrieben. Abschließend werden die mithilfe von Forschungssystemen gewonnenen Erkenntnisse und Erfahrungen unter Betrachtung der vier Qualitäten der Zugänglichkeit diskutiert.

Proxemics in Human-Computer Interaction (HCI) offer new prospects for the design of explicit and implicit interaction techniques to support multiple users and a concurrent navigation for zoomable user interfaces (ZUI). In this paper we describe a navigation concept for zooming and panning based on a multi-display environment using proxemic relations as input (e.g. a user’s location and orientation in physical space to manipulate a viewport). We hope to foster awareness of the topic and to inspire further discussion and research on proxemics in HCI.

In this paper we suggest novel interaction and visualization techniques for a prospective ECML crisis room environment focusing on the analysis of social media data. For this purpose we describe both, concepts providing a Daily Newsflash and concepts for the preparation of Daily Reports referring to a selected incident or crisis situation. The Daily Newsflash is an overview of global incidents regarding humanitarian crises, natural disasters, disease outbreaks, conflicts, etc. Such a bulletin typical contains 1-5 international items with brief facts and 1-5 European items. For selected incidents or crisis situations a Daily Report is prepared. A typical Daily Report consists of one page usually providing a map, key facts, and a brief summary of the situation.

We present two experiments examining the impact of navigation techniques on users’ navigation performance and spatial memory in a zoomable user interface (ZUI). The first experiment with 24 participants compared the effect of egocentric body movements with traditional multi-touch navigation. The results indicate a 47% decrease in path lengths and a 34% decrease in task time in favor of egocentric navigation, but no significant effect on users’ spatial memory immediately after a navigation task. However, an additional second experiment with 8 participants revealed such a significant increase in performance of long-term spatial memory: The results of a recall task administered after a 15-minute distractor task indicate a significant advantage of 27% for egocentric body movements in spatial memory. Furthermore, a questionnaire about the subjects’ workload revealed that the physical demand of the egocentric navigation was significantly higher but there was less mental demand.
