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%(More)
In today's digital control rooms, desktop computers represent the most common interface for process control. Compared to their predecessors -- manual control actuators -- desktop computers enable quick and effective process intervention but they lack in process-related interaction qualities such as haptic feedback and the involvement of motor skills. Thus,(More)
Many tasks performed in multiscale visual spaces require the user to have several foci. Using bimanual interaction, multitouch devices can facilitate the simultaneous definition and exploration of several foci. However, multitouch is rarely used for multifocus navigation, and may limit the interaction to a sequential definition of areas of interest. We(More)
This paper addresses the lack of interaction qualities in control rooms by investigating the potential use of Hybrid Surfaces. As an emerging trend with strong real-world references, they offer the combination of both, the qualities of physical interaction and the potentials of the digital world. To determine their applicability in the given context we(More)
Context-sensitive information is of vital importance to the monitoring of processes in control rooms, but its incorporation in current state-of-the-art user interfaces is inadequate. By looking at a traffic control center as an example, this paper proposes an interaction concept for monitoring complex networks on large remote displays. Our approach is based(More)
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(More)
Kontextsensitive Informationen sind für die Überwachung von Prozessen in Leitwarten von essentieller Bedeutung, werden jedoch in aktuellen Benutzungsoberflächen unzureichend beachtet. Dieser Beitrag stellt am Beispiel einer Verkehrsleitzentrale ein ganzheitliches Interaktionskonzept für die Navigation und Überwachung eines komplexen Netzes vor. Hierzu wird(More)
OPAC interfaces, still the dominant access point to library catalogs, support systematic search but are problematic for open-ended exploration and generally unpopular with visitors. As a result, libraries start subscribing to simplified search paradigms as exemplified by web-search systems. This is a problem considering that systematic search is a crucial(More)
