Important! If you
downloaded CCC 3.2.3 after July 12, there were 2 missing files in
the source code distribution. It does not affect the binaries.
Now you can download the source code for CCC 3.2.3 again.

 t the Virginia Tech CAVE, we perceive a
significant need to address fundamental human factors and usability
issues encountered when working in Virtual Environments (VEs).
Specifically we are focusing on user's primary needs when working
with others across Tele-immersive (T-I)
networks in collaborative VEs. This project is an extension of
a research project in Computer-Supported Cooperative Work (CSCW),
CS5743, where we looked into issues beyond performance which
includes the support of interaction, communication, and collaboration.
A major component of Tele-immersive collaboration is awarness. This
is especially true when participants collaborate in large-scale
potentially crowded VEs. The ability to know where others are in a
VE, what they are doing, and where their attention is focused is
crucial to collaborative interaction. Consequently, a great deal of
our effort has been directed toward supporting collaborative
awareness.Still, there are other issues that contribute to effective collaboration in T-I. For example technology advances have added to the list of various types of VE hardware systems and I/O devices users can afford. In order to promote VE collaboration we observed the need to connect high-end (expensive) but rare visualization systems, e.g. CAVEs, I-Desks, and Immersive Workbenches with less powerful but more widespread desktop computers running VE simulators. |

 he end result is the CAVE
Collaborative Console, which continues to be developed.
The CCC is written using Performer and is based on EVL's
LIMBO virtual environment [Leigh, et. al.] The idea of
the Console began from a need to not only address issues
of awareness, but to somehow provide an interface that
gave the user control over his or her tools. But true to
the Object-Oriented Paradigm, the Console is evolving
into something virtual and need not even exist, from a
user perspective, in order to be used. The latest
iterations of the design and software treat the Console
as a communications manager between LIMBO and whatever
devices the Console is managing. This approach has had
the effect of freeing us, and hopefully others, from the
unstable input problem. The new method is less invasive
of the core LIMBO code and should give T-I applications
developers the flexibility to choose their own input
devices and to easily install their own collaborative
support tools. Current (v3.2.3) interface devices include: 2d Radar, 3d Radar and a Participant List. Functions include: load and unload models, tether, teleport, record and play movements, and see through other people's eyes. CCC also can work in "simulator mode" in a SGI desktop,where the VR display is replaced by a desktop window, and voice command by a floating menubar. This site is intended to assist Tele-Inmersive applications delevopers to easily reproduce and extend our results. By detailing our methods and providing the software devices found here, we hope to motivate continued efforts in this area. |
