View generated using a hyperstructure approach
Approaches for Generating Visualizations
The team have identified four approaches to generating the visualizations, each applicable to different types of data.
This approach directly maps fields from data objects into extrinsic and intrinsic dimensions of the displayed objects - for example might be to map the log of a person's age to the x-ordinate, and map a persons job type to the shape of the displayed object.
An example of this approach is VR-VIBE. Users specify keywords that they wish to use to generate the visualization and place these keywords in 3D-space. Representations of the documents are then displayed in the space according to how relevant each document is to each of the keywords
Some databases support the notion of explicit relations or links between objects (e.g. schema based on entity-relationship models or hyper-media and Network Information Retrieval systems such. Gopher, ARCHIE, WAIS and World Wide Web).
User implementation might be approached in two ways. The first approach is to use real-world metaphors such as a fly-through library interface for a document store; cities, buildings and rooms for organisational information in Directory services; and maps of the physical world for geographical information. A second approach is to allow humans to construct and organise the information terrain themselves on an ad-hoc basis (effectively how files are organised under the desktop metaphor).
