Abstract
Embedded systems are used everywhere. They are complex systems whose failure may cause death or injury to people or may damage the environment are required to be safety safe. Therefore, these systems need to be analyzed. Fault tree analysis is a common way for performing safety analysis. It generates a large amount of interconnected data that itself needs to be analyzed to help different domain experts (e.g., engineers and safety analysts) in their decisions for improving the system’s safety. Additional difficulties occur for the experts in communication and in linking the data (e.g., information of basic events or minimal cut sets) to the actual parts of the system (model). Therefore, a large amount of time and effort is being spent on discussions, searching,and navigating through the data. To overcome this, we present a new metaphor called "CakES" consisting of multiple views visualizing the data generated by fault tree analysis and linking them to the actual parts of the model by intuitive interaction. Using the interaction techniques of CakES the user can directly explore the safety related data without navigating through the fault tree while retaining an overview of all critical aspects in the model.

Framework for Comprehensive Size and Resolution Utilization of Arbitrary Displays

Authors: Taimur Khan, Daniel Schneider, Yasmin Al-Zokari, Dirk Zeckzer, and Hans Hagen

Published in: Dagstuhl Follow-Ups, Volume 2, Scientific Visualization: Interactions, Features, Metaphors (2011)


Abstract
Scalable large high-resolution displays such as tiled displays are imperative for the visualization of large and complex datasets. In recent times, the relatively low costs for setting up large display systems have led to an highly increased usage of such devices. However, it is equally vital to optimally utilize their size and resolution to effectively explore such data through a combination of diverse visualizations, views, and interaction mechanisms. In this paper, we present a lightweight dispatcher framework which facilitates input management, focus management, and the execution of several interrelated yet independent visualizations. The approach is deliberately kept flexible to not only tackle different hardware configurations but also the amount of visualization applications to be implemented. This is demonstrated through a scenario that executes four interrelated visualizations equally well on both a 5 PC tiled-wall and a single desktop. The key contribution of this work is the ability to extend the tiled-wall to work with multiple applications for enhanced size and resolution utilization of such displays.
