There are many interface schemes that allow users to work at, and move between, focused
and contextual views of a dataset. We review and categorize these schemes according to …

Geovisualization applications typically organize data into layers. These layers hold different
types of geographical features, describe different characteristics of the same features, or …

We propose a patterns-based approach to evaluating data visualization: a set of general
and reusable solutions to commonly occurring problems in evaluating tools, techniques, and …

Most of the maps used today are what we call pan-scalar maps, ie interactive zoomable
applications comprised of numerous maps of a particular area at different zoom levels (ie …

Applications supporting navigation in large networks are used every days by millions of
people. They include road map navigators, flight route visualization systems, and network …

The advent of ultra-high resolution wall-size displays and their use for complex tasks require
a more systematic analysis and deeper understanding of their advantages and drawbacks …

Electronic test and measurement systems are becoming increasingly sophisticated in order
to match the increased complexity and ultra-high speed of the devices under test. A key …

The most common techniques for navigating in multiscale visual spaces are pan, zoom, and
bird's eye views. However, these techniques are often tedious and cumbersome to use …

Focus+ context techniques such as fisheye lenses are used to navigate and manipulate
objects in multi-scale worlds. They provide in-place magnification of a region without …

In exploring 3D environments from a first-person viewpoint, the narrow field-of-view makes it
difficult to search for an off-screen object, a task that becomes even harder if the user is …
