 Visage Link is one of the components of DARPA's Collaboration, Visualization, and Information Management (CVIM) program. It is also one part of the Visage project, which is an advanced direct-manipulation, information-visualization environment currently under development at MAYA Design Group. Visage Link extends Visage's capabilities to include collaboration among geographically distributed users.

Visage Link facilitates collaboration among users by providing an architecturally sound framework for shared and private workspaces. In Visage Link, the set of data concepts in a Visage frame (a component that shows different views and arrangements of data elements) provides a shared domain of discourse. Akin to teleconferencing, Visage allows collaborating users to exchange and view data in shared frames. Visage Link also allows different users to view different representations of the same data, each in a manner that enhances their ability to contribute to a distributed problem.

For example, two users may be visualizing a group of radio stations, but one may be using a map frame while the other is viewing a chart showing the output power of each station. Visage Link gives the users the ability to manipulate the shared concepts by adding and removing them from the shared set, by using drill-down and roll-up navigation, and by dragging them to new visualizations.

Infrastructure
Visage Link's infrastructure is rapidly evolving to include more options and more robust mechanisms for sharing concepts, including replicated, shared, and distributed repositories. MAYA will also be investigating methods of sharing between desktop- based Visage frames and mobile, handheld devices.In addition, MAYA intends to integrate Visage with components of other ICV-development technologies such as the MASH project.

Self-Visualization
Since Visage is a visualization environment, it can be "turned back on itself" in order to visualize the collaboration and interaction that takes place when people use Visage Link. To this end, Visage Link is being built in such a way that viewing users, groups, connectivity, and status can be done within Visage itself.




A Shared Frame
Two users can collaborate to analyze data by using a a shared frame.




A Polymorphic Shared Frame
Collaborating users can view different representatives of the same data with polymorphic shared frames.
