Increasing amounts of data and information and the availability of fast
digital network access (e.g., the World Wide Web) have created a demand for
querying, accessing, and retrieving information and data. Unlike most
scientific numerical data, information is abstract, having no physical form
or representation. Information Visualization involves the conversion of the
abstract into concrete visual representations and creation of user
interfaces to support tasks such as searching, data mining, discovery, and
identification. Visualization uses the techniques of interactive graphics
and imaging and relies on the visual system to perceive information.
Information visualization is an increasingly important research and
development area and is crucial for the success of the information
revolution. Effective visualizations will enable users from all walks of
life to use the information highway easily and efficiently. Among the
emerging new research and development areas are interaction with large data
bases, visualization of text contained in large corpora, and interaction
with multi-dimensional information and data.
This two-day workshop was held June 24-25, 1997, in Paris, France.
Co-chaired by Nahum Gershon (The MITRE Corp.) and Jacques-Emile Dubois
(CODATA International), it had an international committee of visualization
experts from nine countries. The goals of the workshop were to bring
together researchers and developers in information from Europe, the United
States and Canada for intensive brain-storming to accomplish the following:
* Survey current activity in information visualization in Europe and the
United States.
* Identify research and development issues in visualization.
* Forge research collaborations.
Although there has been a great deal of development of methods for
visualizing diverse types of data and information, few algorithms and
methods have been implemented to solve real-world problems, especially in
North America. The focal point of this workshop was on implementing
visualization methodology. Attendees to this workshop came from France,
Sweden, Germany, Italy, Netherlands, United Kingdom, Hong Kong, United
States and Canada.
Discussions of "where we are" centered on how information visualization
merges the areas of user interfaces, scientific visualization and
databases. Information visualization differs from statistical or scientific
visualization in its efforts to communicate the structure of information
and improve access to large data repositories. Visual data mining
techniques were discussed.
Future directions, or "where we are going," include:
- augmented reality by embedding virtual information in the physical world,
using see-through displays.
- wearable/mobile user interfaces to make information available anytime and
anywhere.
- controlling complex, dynamic, shared information environments.
Also, user interfaces for virtual worlds will be enhanced by integrating 3D
thematic layers, such as elevation maps, 3D simulation data, and landmarks,
into browsable virtual worlds, and by "wayfinding," an ability to find a
particular location in an expedient manner and recognize where you are.
