|The goal of the Continuum
Project is to develop integrated ubiquitous tools and environments to
enhance collaboration amongst distantly located knowledge workers, such as
scientists and engineers.|
The Continuum centers around the concept of distributed, collaborative, "amplified work environments" where collaborators gather to solve problems assisted by advanced collaboration, computation and visualization technologies. Visualization and collaboration technologies include interactive stereoscopic computer graphics, multi-site audio/video conferencing, and high resolution tiled graphics displays. Backing these technologies are clusters of PCs connected over extremely highspeed gigabit networks.
The following describe technologies that are currently being developed:
|Tiled high resolution displays that display both AccessGrid conference windows
and information artifacts such as text documents, web pages, spreadsheets,
and scientific visualizations.These tiled displays must be supported by a
compute cluster with sufficient bandwidth (such as Gigabit networks) to
interconnect the displays with other remotely located displays and
supercomputers and metacomputing clusters.
provides a hardware and software independent way to distribute high
resolution content to collaborators.
TeraVision is a real-time method to distribute visual imagery from
any graphics platform over the Access Grid that requires no setup,
software, or hardware changes to the user's computer.
The goal is to provide one solution for what is commonly
referred as the "Docking Problem or Display Pushing Problem" on the AccessGrid.
That is, to provide ameans for anyone on the Access Grid to plug-in,
for example their laptop, and to deliver a presentation without having
to install or configure any software, or distribute any of the data files,
|The Access Grid Augmented Virtual Environment
(AGAVE)- which appends a passive
stereoscopic display to an Access Grid to allow collaborators to share
true three dimensional content such as engineering or scientifiic
visualizations. The AGAVE will also work compatibly with existing high
performance immersive visualization systems such as CAVEs and
|Access Grid - to
- Go - allows traveling users to
attend meetings from remote locations. Furthermore the video streaming
capability allows scientists to monitor remote equipment or stream
visualizations directly from immersive environments such as the
The VVP program developed for the PocketPC is a prototype of this technology.
|Technologies to establish life-like meeting
presence- in particular for the disabled who may find it difficult to
attend meetings at remote locations. The AccessBot, a remotely deployable robot that uses a large 42
inch plasma screen in portrait mode, portrays remote collaborators in true
life size- hence allowing them to command equal presence at meetings. Our
experience with the AccessBot has shown that the presence of the remote
participant comes through so strongly that the mechanical shell of the
surrogate disappears entirely. We believe that by merging AccessBots with
AccessGrids one could support deictic referencing that is completely
missing in video conferencing but is essential for establishing common
ground in real face to face meetings.
At the Electronic Visualization Laboratory, two Continuum spaces have been
built to facilitate hardware and software development and human factors study
to understand how teams will work in rooms that are wallpapered with seamless
displays. Another one is also operational at the Technology Research Education
and Commercialization Center (TRECC) in DuPage County, Illinois.
