The ever-increasing presence of hypertext as a mechanism for browsing information has necessitated study of how to counter usability difficulties inherent to hypertext as a medium. The conjunction of semantically typed links with associated visual behaviours are proposed, as a means to amending typical navigation problems. Types provide structure to the connected information set, enabling users to better conceive of the overall structure, while behaviour, taking the form of key-framed animations from link source to destination, allow users to perceive structural relations. A set of link type and behaviour combinations, or link roles, implemented in Hypercept are outlined

Virtual Environments (VEs) have the potential to revolutionize traditional product design by enabling the transition from conventional CAD to fully digital product development The presented prototype system targets closing the **digital gap” as introduced by the need for physical models such as clay models or mockups in the traditional product design and evaluation cycle. We describe a design environment that provides an intuitive human-machine interface for the creation and manipulation of three-dimensional (3D) models in a semi-immersive design space, focussing on ease of use and increased productivity for both designer and CAD engineers

In this work, we present our experience of utilizing audio-visual data mappings for GIS-based information visualization. The application we choose is a GIS-based system for visualizing crime in a city. In this application, we enhance the pseudo-colored visual presentation of crime information by mapping data to several sound parameters — volume, balance, bass and treble. Our motivation for choosing sound in addition to vision is guided by our belief that data quantities mapped to various colors in a coloring scheme do not always clearly describe the information being presented for many different tasks that visualization is expected to support In many cases additional data characteristics can be conveyed to the user through sound to enhance the performance of the user on those tasks. We have conducted experiments with human users to compare the performance of users on visual data mapping alone vs. visual and sound data mappings together on several tasks including estimates of raw data values, local averaging, and global comparison. In most cases, we found that the use of bi-modal visual and sound data mappings together provided more accurate understanding of data displays

We built a tool to visualize and explore program execution traces. Our goal was to help programmers without any prior knowledge of a program, quickly get enough knowledge about its structure so that they can make small to medium changes. In the process, a number of problems were faced and tackled concerning the efficient use of screen space, interaction with multiple concurrent views, and linking of asymmetric views

Complex information systems are very difficult to represent and users often have problems to find relevant information; this is the case with Web navigation: users feel “lost”. Data contained in such systems can often be organized hierarchically, thus it is possible to represent it as a tree. However, most visualizations are cluttered because of the amount of information to display. We propose to solve these problems by using Virtual Reality (VR) techniques. After reviewing different 3D visualization methods, we decided to use cone trees. Unfortunately, the enhancement provided by graphic methods is not sufficient when hierarchies are very large; in such cases, trees must be pruned with filtering methods. We chose to structure and manipulate data with the eXtensible Markup Language [19]. XML allows the description and organization of any type of information. In this paper, we show how we implemented these principles in the field of network management (for networks based on Synchronous Digital Hierarchy (SDH) equipment). The application we developed eases navigation in data extracted from the Management Information Base (MIB) and accelerates access to useful information. In the future, we will apply these results to Web navigation.

Virtual environment (VE) technologies have considerable potential to extend the power of information visualization methods, and those of scientific visualization more broadly. Our specific focus here is on VE technologies as a medium for geographic visualization and on some of the challenges that must be addressed if the potential of VE is to be realized in this context.

Using inductive learning techniques to construct explanatory models for large, high-dimensional data sets is a useful way to discover useful information. However, these models can be difficult for users to understand. We have developed a set of visualization methods that enable a user to evaluate the quality of learned models, to compare alternative models, and identify ways in which a model might be improved We describe the visualization techniques we have explored, including methods for high-dimensional data space projection, variable/class correlation, instance mapping, and model sampling We show the results of applying these techniques to several models built from a benchmark data set of census data.
