Abstract:
We present the Virtual Data Visualizer, a highly interactive, immersive
environment for visualizing and analyzing data. VDV is a set of tools for
exploratory data visualization that does not focus on just one type of
application. It employs a data model with data arranged hierarchically in
classes that can be modified by the user within the virtual environment.
The class structure is the basis for bindings or mappings between data
variables and glyph elements, which the user can make, change, or
remove. The binding operation also has a set of default operations so that
the user can quickly display the data. The VDV requires a user interface
that is fairly complicated for a virtual environment. We have taken the
approach that a combination of more-or-less traditional menus and more
direct means of icon manipulation will do the job. This work shows that a
useful interface and set of tools can be built. Controls in VDV include a
panel for controlling animation of the data and zooming in and out. Tools
include a workbench for changing the glyphs and setting glyph/variable
ranges and a boundary tool for defining new classes spatially.
