We present a visualization framework integrated in a context-aware system that uses a common underlying stream processing middleware for tight integration of data accessing, processing, and visualization. Context-aware systems are often realized on mobile devices that do not have the computational power to perform complex tasks. Therefore, a dedicated hardware infrastructure might be required for...
In the context of multi-developer projects, where several people are contributing code, developers must deal with concurrent development. Collaboration among developers assumes a fundamental role, and failing to address it can result, for example, in shipping delays. We argue that tool support for collaborative software development augments the level of awareness of developers, and consequently, help...
Many network visualizations make the assumption that an administrator has previously determined the subset of data that should be visualized. Yet the problem remains that if the visualization provides no insight into the network events that warrant further consideration, then the administrator must go back to the data to determine what should be visualized next. This is a critical issue given the...
Context-awareness is increasingly becoming an important capability in devices for ubiquitous computing environments. These devices use on-board sensors and history of user interaction to collect data that are used to adapt their behavior to suit with the current environment. There is a need to support real-time software in ubiquitous computing environments, especially in reactive systems, such as...
A common goal in graph visualization research is the design of novel techniques for displaying an overview of an entire graph. However, there are many situations where such an overview is not relevant or practical for users, as analyzing the global structure may not be related to the main task of the users that have semi-specific information needs. Furthermore, users accessing large graph databases...
