Short description

Tasks that involve large information spaces overwhelm workspaces that do not support efficient use of space and time. For example, case studies indicate that information often contains linear components, which can result in 2D layouts with wide, inefficient aspect ratios. The paper describes a technique called the Perspective Wall for visualizing linear information by smoothly integrating detailed and contextual views. The Perspective Wall technique takes advantage of hardware support for 3D interactive animation to imitate the architecture of the eye system. It folds a 2D layout into a 3D wall that smoothly integrates a region for viewing details with perspective regions for viewing context. This intuitive distortion of the layout provides efficient space utilization and allows smooth transitions of views. Analysis of the Perspective Wall technique indicates a threefold improvement over simple 2D visualizations.The resulting visualization supports efficient use of space and time.
