IVPrototype is an Information Visualization Prototype for the visualization of both geometrical and non-geometrical data. Our goal is to provide a generic system that automatically generates data visualization and dynamically adapts the interface according to the data in order to control the amount of information displayed. The information is organized in one or several information groups, whic...

Salience detection is a principle mechanism to facilitate visual attention. A good visualization guides the observer’s attention to the relevant aspects of the representation. Hence, the distribution of salience over a visualization image is an essential measure of the quality of the visualization. We describe a method for computing such a metric for a visualization image in the context of a gi...

Within the framework of the information retrieval, the restitution of the documents is carried out according to their calculated relevance score. They correspond to a precise request. However questions arise as for the representation of documents and requests like their mapping. The graph is used as data visualization, without requiring mathematical knowledge. This article presents the contribu...

The importance of information visualization as a means of transforming data into visual, understandable form is now embraced across university campuses and research institutes worldwide. Yet the role of designers in this field of activity is often overlooked by the dominant scientific and technological interests in data visualization, and a corporate culture reliant on off-the-shelf visualizati...

Direct-touch interaction is receiving an increasing amount of attention in the HCI domain and has recently been applied to some problems in information visualization. However, the field of scientific visualization has not seen much work on how direct-touch interaction could benefit the interactive visualization process. One reason may be that scientific visualization typically deals with datase...

We revisit the design space of visualizations aiming at identifying and relating its components. In this sense, we establish a model to examine the process through which visualizations become expressive for users. This model has leaded us to a taxonomy oriented to the human visual perception, a conceptualization that provides natural criteria in order to delineate a novel understanding for the ...

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 ...

One form of information visualization is called ambient display. It is defined as the use of aesthetically pleasing displays of information which sit on the periphery of a user’s attention (Manko, Dey, Hsieh, Kientz, Lederer and Ames 2003). Financial visualization is the practice of making large financial datasets into images . In this paper, we describe a research project which uses watercolor...
