In this position paper, we propose to investigate novel technologies for evaluating information visualization systems: physiological sensing. We review existing technologies and describe how advances in physiological sensing open a novel perspective for the evaluation of information visualization systems.

Received: 2 November 2004 Revised: 5 April 2005 Accepted: 11 April 2005 Abstract The use of multivariate information visualization techniques is intrinsically difficult because the multidimensional nature of data cannot be effectively presented and understood on real-world displays, which have limited dimensionalities. However, the necessity to use these techniques in daily life is increasing a...

Networks that evolve over time, or dynamic graphs, have been of interest to the areas of information visualization and graph drawing for many years. Typically, its the structure of the dynamic graph that evolves as vertices and edges are added or removed from the graph. In a multivariate scenario, however, attributes play an important role and can also evolve over time. In this chapter, we char...

This paper presents our approach to volume modelling which combines volume representations by voxel data and by continuous real functions. We discuss the main differences between direct volume visualization and modelling with voxel data, questions of conversion between two representations including volume reconstruction from contour data. We illustrate the approach by several advanced operation...

The aim of this research is to describe a useful approach for supporting creativity and problem-solving in the design of Information Visualization software. This type of software is useful for helping people to understand large or complex collections of data by making the data easier to see and use. Because it can be so helpful, many people are motivated to create visualization software to addr...

Volumetric imaging modalities are increasingly being used in surgical applications. However, visualizing the 3D information contained in these datasets effectively on a 2D display is a challenging problem. Most important issues to overcome are the occlusion of different anatomical features of each other and the difficulty of visualizing the depth information of a given pixel in a 2D image. More...

Spatial visualisation skills and interpretations are critical in the design professions, but traditionally difficult to effectively teach. Visualization and multimedia presentation studies show positive improvements in learner outcomes for specific learning domains. But the development and translation of a comparative visualization pedagogy between disciplines is poorly understood. This researc...

This paper presents the concept of alternative presentation components in the context of mobile visualization. A criterion for distinguishing between media with respect to their preparation for the presentation of information is introduced and the conventional visualization pipeline is extended to accommodate the needs of mobile information presentation. The concept is illustrated by some examp...

Computer-assisted interactive visualization has become a valuable tool for discovering the underlying meaning of tabular data, including categorical tabular data. The capabilities of the more traditionally mundane kinds of pictures like scatter plots can be expanded to usefully depict categorical tabular data by incorporating annotations and transforms, and by integrating the extensions into an...

More and more, the products of statistical analysis that we encounter in our everyday lives come in the form of data visualizations. Visualizations have the advantage of being easier to interpret for many people, but they also give the impression of being a form of absolute truth. As with any presentation method, though, visualizations can be manipulated by their creators to show the story they...
