....problems become. Many of these problems are typical hypertext problems, others are typical to the Web. In the hypertext field it is generally assumed that navigation in hypertext is not difficult per se but that it can be easy when the structure of the information space is made explicit [SHUM90]. See also [KiHi94] for a study that transfers way finding knowledge to the hypertext field. Ironically the most popular feature of the WWW the transparency of the linking process works against making the structure of the information space explicit. It is easy and pleasurable to browse or ....

....Representations of space have to be designed by keeping these issues in mind because otherwise the representation can lead to a wrong perception of the space. 2.3. Spatial memory Human spatial behavior is dependent on the individual s mental representation of the spatial environment [DoSt73] [SHUM90]. The representation is used to direct action and the experiences are used to further modify the representation. The various models of the ability to learn an environment and to remember spatial relationships form the basis to understanding misjudgments in spatial relationships. This section ....

....any support tool will be able to access appropriate parts of the domain knowledge in a reliable manner. The problem here is one of presenting large information structures in a manageable way. Research on related issues is ongoing in the hypertext, database and knowledge based systems communities [Shu90, RH89, DBSB91] Finally, it is felt that full specification of systems such as those used in air traffic control might best be done by using a number of different formalisms to specify different aspects of these systems. This raises a need for a theoretical framework within which specifications ....

....This concept somehow reflects the infolded and fractal ordering of natural space. 3.2. 1 Visualising Hyperspaces There are similarities between navigating through everyday environments like cities or landscapes and navigating through information structures like hypertext or hypermedia systems [Shu90] Thus it is quite obvious to use those real life environments as metaphors for visualising hyperspaces. Virtual worlds built with such metaphors provide intuitive means for browsing information spaces. Spatial user interfaces using physical space as a metaphor for information space, create ....

....world may improve wayfinding in virtual worlds as well. Research is needed to validate this claim (e.g. 17] 40] In this vein, Shum notes that users cognitive maps of hypermedia clearly include landmarks, paths, and 11 nodes; districts and edges could be usefully added via UI metaphors [72]. Finally, Lynch s rich research methodology could be adapted and extended for electronic worlds (e.g. 22] 52] Later research by Passini built on Lynch s wayfinding research [61] Where Lynch focused on the physical and spatial characteristics of the urban environment, Passini focused on ....

....such an environment [34] These two sets of theoretical recommendations are complementary; research is needed to determine the relative importance and roles of the two approaches. In related research, Shum discusses the properties and benefits of Euclidean (physical) and virtual (semantic) spaces [72]. Virtual space, on the one hand, has only relative locations, since it has no global or fixed coordinate system. Euclidean space, on the other hand, has absolute locations. In any case, in electronic worlds of each type, an information node s location should relate meaningfully to its content. In ....
