Case study. Visualising cyberspace: information visualisation in the Harmony Internet browser

The explosive growth of information systems on the Internet has clearly demonstrated the need to organise, filter, and present information in ways which allow users to cope with the sheer quantities of information available. The scope for visualisation of Gopher and WWW spaces is restricted by the limitations of their respective data models. The far richer data model supported by the Hyper-G Internet information system is exploited by its Harmony client to provide a number of tightly-coupled, two- and three-dimensional visualisation and navigational facilities, which help provide location feedback and alleviate user disorientation.
