Scientists, engineers and physicians are now confronted with a fire hose of data. Immersive visualization environments provide these users with a novel way of interacting and reasoning with large datasets. They allow them to utilize the entirety of their visual bandwidth, effectively engulfing the user in the data and enabling collaborative interaction. We present a custom-built 5-wall Cave environment,...
Managing networks and services in large virtual enterprises often requires significant expertise to decipher and reconcile information coming from several heterogeneous sources. This presents a significant challenge as the person with the network management expertise is not necessarily the person who has the task or vision of how to maximize the value of these services. Conversely it would be valuable...
Although static ranked lists remain the dominant Web search interface, they can limit the ability of Web searchers to find desired information when it is buried deep in the collection of search results. Web search visualization and Web search personalization are two active research directions that have shown promise for improving the user experience while searching the Web. In this paper, we propose...
An effective program comprehension is reached when it is possible to view and relate what happens when the program is executed, synchronized with its effects in the real world concepts. This enables the interconnection of program's meaning at both problem and program domains. To sustain this statement we need (i) to develop a tool which provides and synchronizes views at both domains, and (ii) to...
Class hierarchies are key to flexible object-oriented design, but can also burden program comprehension activities when improperly designed or documented. This tool demo presents an Eclipse plug in called PATROOLS. It implements two software visualizations that capture the polymorphic usage of a class hierarchy by its clients, and can support understanding and quality assessment tasks related to class...
Enabling users to accurately perceive the correct depth of occluded objects is one of the major challenges in user interfaces for Mixed Reality (MR). In this paper, we present an evaluation of depth perception in handheld outdoor mixed reality environment in far-field distances through two photorealistic visualizations of occluded objects (X-ray and Melt) in the presence and absence of a depth cue.
A bibliographic database houses vital information pertinent to the research community. By extracting implicit hidden information in such data collections, social networks can be used to represent the various data inter-relationships.In this paper, we propose a new method for the discovery and visualization of research communities from bibliography information. We utilize the hierarchical overlapping...
Understanding software systems comprises the analysis of different aspects of the respective systems, such as dynamic and static analysis with all their facets. Consequently, developers study different kinds of information and create different mental models. We introduce a visualization technique that facilitates cross referencing mental models, in particular models that describe the structure and...
Source Viewer 3D (sv3D) is a software visualization tool, based on a 3D extension of the file map metaphor. Sv3D has been developed as an independent visualization front end that represents source code and associated metrics as 3D metaphors, namely containers and poly cylinders. We developed a new version of sv3D as an Eclipse plug-in. Most of the functionality of the original tool is preserved, while...
While automatic generation of funny texts delivers incrementally better results, for the time being semiautomatic generation can already provide something useful. In particular, we present an interactive system for producing humorous puns obtained through variation (i.e., word substitution) performed on familiar expressions. The replacement word is selected according to phonetic similarity and semantic...
Issue tracking repositories contain a wealth of information for reasoning about various aspects of software development processes. In this paper, we focus on bug triaging and provide visual means to explore the effort estimation quality and the bug life-cycle of reported problems. Our approach follows the micro/macro reading technique and uses a combination of graphical views to investigate details...
The different perspectives stakeholders and requirements engineers have on a problem are a major hindrance to derive useful requirements. While formal requirements models are well suited for excluding inconsistent requirements, prototypes presented to stakeholders are very effective to ensure valid requirements. In this position paper we report about our vision to combine both approaches in form of...
Requirements engineering visualization is a rapidly growing field of research; however, the specific characteristics of what makes for effective visualizations during a particular engineering phase have not yet been distinguished. Visualizations, when coupled with traditional practices, augment the ability of resulting requirements artifacts to reach a wide range of stakeholders and provide for a...
Emotional requirements capture the game designer's vision for the player's emotional experience and are used to facilitate communication between pre-production and production teams. However, production-phase deficiencies in emotional requirements have been identified. In this work, we extend the definition of emotional requirements to include emotion prototypes and emotion markers and present improved...
Summary form only given. Visual notations form an integral part of the language of requirements engineering (RE), and have dominated RE research and practice from its earliest beginnings. An RE method without a visual representation is almost unheard-of. The primary reason for using visual notations is to exploit the power of human visual processing and thereby optimise human communication and problem...
This paper presents 'The Sensitive Tapestry', an interactive installation using body-input as a nontraditional user interface. The technical basis for this kind of media-enabled environment is a thermal imager that captures the activities in public areas at a large scale. The installation has been developed as a prototypical example in architectural education at the ETH Zurich, Science City. The aim...
The rapid increase in deployment of policy-based access control systems faces security administrators with the daunting task of managing a large number of complex access control policies. Several policy analysis types, (e.g., policy similarity, policy conflict and change-impact) have been proposed to help administrators maintain consistent and conflict-free policy repositories. However, there has...
The virtual environmental planning systems project (VEPs) proposed an alternative approach to planning consultation by allowing people to view and leave comments about planning developments using 3D visualization software in a Web browser, within the context of an existing landscape or cityscape.The software developed by VEPs allows users to freely explore and interact with 3D models and make comments...
Network scans visualization provides very effective means for to detection large scale network scans. Many visualization methods have been developed to monitor network traffic, but all the techniques or tools still heavily rely on human detection. They seldom consider the importance of network event characteristics to the network data visualization, and cannot detect slow scans, hidden scans etc....
In this paper, we propose a neural-network-based visualization system of geographic tendency. In general, there are some needs of understanding statistical data of geographic tendency, such as geographic marketing data, real-estate prices, and so on. The main purpose of the proposal is to visualize the tendency of these data online with interactive mapping systems, such as Google Maps. The proposed...
