Useful techniques for information visualization allow engineers or analysts to produce works of art. A work entitled “Financial Reminiscences” is an example of such works. This work has been produced using a visualization technique for financial analysis. This technique is not only a tool for generating images. It is closely related to the information visualized in the work. Thus, the audience ...

Traditionally, evaluation studies in information visualization have measured effectiveness by assessing performance time and accuracy. More recently, there has been a concerted effort to understand aspects beyond time and errors. In this paper we study enjoyment, which, while arguably not the primary goal of visualization, has been shown to impact performance and memorability. Different models ...

100-150 words) Designing a virtual environment and its interactions is a difficult task because of the complexity of specifying non-deterministic relationships between multiple objects. We present a system to help novice designers create interactions in a virtual environment. Our system uses triggersets (event-condition-action triads) for entering interactions. It provides multiple visualizatio...

In this paper, we present a method for the simplification of the geometry of 2D and 3D objects. Our apporach allows us to perform both uniform and non-uniform simplification. Our purposes are twofold. On the one hand, we can make matching algorithms faster in object detection using simplified geometries. Moreover, with non-uniform simplification we can adjust the quality of the visualization of...

PURPOSE To evaluate the frequency of visualization, thickness and location of the normal appendix at non-enhanced spiral computed tomography (CT). MATERIALS AND METHODS Low-dose spiral CT scans obtained for renal colic assessment in 243 patients were retrospectively reviewed. The frequency of visualization, thickness and location of normal appendices were recorded without knowledge of the pat...

In this study, we present an application paradigm in which an unsupervised machine learning approach is applied to the high-dimensional influenza genetic sequences to investigate whether vaccine is a driving force to the evolution of influenza virus. We first used a visualization approach to visualize the evolutionary paths of vaccine-controlled and non-vaccine-controlled influenza viruses in a...

Speculative design is an emerging rhetorical strategy in design practices and research to raise public awareness in social agendas that have been little explored. As a stream of this type of research, we propose speculative visualization that aims to achieve speculative design by utilizing techniques from data visualization and graphic design. Specifically, speculative visualization represents ...

We analyze the Austrian social insurance system, focusing on the labor market as well as the pension system, on behalf of governmental institutions and other official stake holders. Visualizations play an increasingly important role. We present two examples from current projects – a very simply static one and a more complex interactive one – that both demonstrate the benefits of visualizations ...

We are interested in questions of improving user control in bestmatch text-retrieval systems, specifically questions as to whether simple visualizations that nonetheless go beyond the minimal ones generally available can significantly help users. Recently, we have been investigating ways to help users decide—given a set of documents retrieved by a query—which documents and passages are worth cl...
