FWF - Caleydoplex - Caleydoplex - Collaborative Information Exploration

Project: Research project

Project Details


Critical decisions involving a lot of data are rarely made by a single person, but are rather discussed and evaluated
by a team of experts. Examples are doctors deciding for treatment of severe illness, emergency services having to
react to ongoing crises, or engineers collaborating to make technical decisions concerning expensive products.
These activities can be assisted by information visualization tools. However, traditional information visualization
rarely considers the collaborative nature of data analysis tasks.
The foundation of our research proposal is the extension of a multiple view visualization system to a multi-display
environment. Multiple view visualization shows data in different representations and thereby accommodates for
different knowledge backgrounds and user preferences. Multi-display environments turn unused wall and table
spaces into interactive surfaces using off-the-shelf projection technology and integrate private workstations
smoothly into this shared interactive workspace. Our research aim is the design and creation of a co-located
collaborative information visualization workspace dealing with two principal challenges: display space management
and collaborative interaction techniques. Intelligent display space management adopts information visualizations
and placement of views automatically to the physical display properties and supports the users interacting with the
environment. Combined with visual linking of related data entities distributed across the environment, it will help
to establish a common knowledge ground. Collaborative interaction techniques are required to organize such a rich,
but potentially complex environment. We will investigate high-level activity support for typical tasks in shared
information workspaces, personalized actions, and how users can maintain awareness of each other's activities.
The proposed research benefits from two ongoing projects at Graz University of Technology: Deskotheque delivers
the basic technology necessary for collaborative work in multi-display environments, while Caleydo, a
visualization project from the biomedical domain, provides an excellent use case, including the necessary experts
willing to collaborate in studies. Using these frameworks, we plan to conduct several usability studies, with
prototypes of different levels of sophistication.
