Abstract
This paper describes a minimally-immersive three-dimensional
volumetric interactive system for the visualization of
information. The system, SFA, uses glyph-based volume rendering,
enabling more information attributes to be visualized than traditional
2D and 2.5D information visualization systems. The use of glyph
rendering allows many information attributes (information space
dimensions) to be visualized and perceived. Two-handed interaction
using three-space magnetic trackers and stereoscopic viewing are
combined to produce a minimally-immersive interactive information
visualization system that enhances the user's three-dimensional
perception of the information space. This new system capitalizes on
the human visual system's pre-attentive learning capabilities to
quickly analyze the displayed information. We describe the usefulness
of this system for the visualization of document similarity within a
corpus of textual documents. SFA allows the three-dimensional
volumetric visualization, manipulation, navigation, and analysis of
multivariate, time-varying information spaces, increasing the quantity
and clarity of information conveyed from the visualization as compared
to traditional 2D information systems.
