Abstract:
We propose a Virtual Reality interface for creating and manipulating
textual and hypertextual information. Many current hypertext systems
include concept maps in two dimensions. Our system, called the World
Processor, offers the user a three-dimensional concept map. It allows
the user to move through the map while exploring existing objects and
their associated texts and adding new objects and texts. We discuss a
number of interface issues raised by three-dimensional hypertext and then
describe the World Processor as an attempt to address some of these
issues. Of particular interest in the World Processor interface are its
point-and-shoot selection technique, its methods for reading and editing
text in 3D, its widgets for creating and modifying conceptual objects,
and its auditory as well as visual feedback. Possible applications for
three-dimensional hypertext include CSCW (particularly collaborative
writing) and authoring systems for computer-based training.
