Generalizing Focus+Context Visualization
نویسنده
چکیده
Focus+context visualization is well-known from information visualization: certain data subsets of special interest are shown in more detail (locally enlarged) whereas the rest of the data is provided as context (in reduced space) to support user orientation and navigation. The key point of this work is a generalized definition of focus+context visualization which extends its applicability also to scientific visualization. We show how different graphics resources such as space, opacity, color, etc., can be used to visually discriminate between data subsets in focus and their respective context. To furthermore demonstrate its general use, we discuss several quite different examples of focus+context visualization with respect to our generalized definition. Finally, we also discuss the very important interaction aspect of focus+context visualization.

Toward User Interface Migration for Scientific Visualization
Visualization is a key component of the scientific investigation process, but different contexts (e.g. varying numbers, locales and expertise of users, heterogeneous infrastructure components, etc.) require different toolsets for workflow management. We focus on interactive techniques for engaging visualization, especially those that emphasize physical interaction as embodied in tangible and ge...
متن کاملA Framework for Focus+Context Visualization
Focus+context visualization techniques aim to give users integrated visual access to both details and overview of a data set. This paper gives a systematic account of such visualization techniques. We introduce the notion that there are different levels of information visualization, with focus+context being a second-level visualization, and illustrate this with examples. We then provide a forma...
متن کاملRedefining the Focus and Context of Focus+Context Visualizations
The increasing diversity of computers, especially among small mobile devices such as mobile phones and PDAs, raise new questions about information visualization techniques developed for the desktop computer. Using a series of examples ranging from applications for ordinary desktop displays to webbrowsers and other applications for PDAs, we describe how a focus+context technique, Flip Zooming, i...
متن کاملFocus+Context Display of the Visualization Process
The purpose of the visualization process is to extract insight from information via visual representations. However, the visualization process itself is information and can be in turn visualized. This work describes a method for visualizing the visualization process using a new focus+context radial graph algorithm. Four different metrics for extracting information from the visualization are exa...
متن کاملExtended Focus & Context for Visualizing Abstract Data on Maps
Traditionally, the subject of cartography has been geographic data, while information visualization has dealt with abstract, non-spatial information. With the ever increasing amount of data harvested worldwide, more and more of this data includes both geographic and abstract information at the same time. Efficient visualization of this data calls for the combination of maps with techniques for ...
