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)
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)
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)
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)
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)
In the VAST Challenge 2009 suspicious behavior had to be detected applying vi s ual analytics to heterogeneous data, such as network traffi~ , so~i al network enriched with gco-spatial attributes. and finally video surveillance data. This paper descri bes some of the awarded parts from our sol.ution entry.
Self-monitoring is an important part of behavior intervention technologies. In order to increase the effectiveness of self-monitoring, we do not only have to track data but also give feedback to the user. In the interdisciplinary project SmartAct, we aim at developing and empirically testing the effectiveness of an open access toolbox for mobile, real-time(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)
Personalized and contextual interventions are promising techniques for mobile persuasive technologies in mobile health. In this paper, we propose the "fingerprints" technique to analyze the users' daily behavior patterns to find the meaningful moments to better support mobile persuasive technologies, especially mobile health interventions. We assume that(More)
