.... In the case of the computer, this is really a re patterning of an alternative city, as the post modern audience finds things behind the screen far more interesting than things in front of it, and tends to be beckoned into the escapist receding space of the electronic matrix (Gibson 1984; Dieberger 1995). In the Cybercity place is relatively non existent, because the specifics of time, space, and architecture which are required to define and distinguish places have been eradicated. The Cybercity lacks a center, standing it in stark contrast with the material city, which guides travelers on its ....

....spatial needs of # # domains. Earlier Spatial Data Handling symposium papers have analyzed the structure and role of spatial metaphors [Kuhn 1990; Kuhn 1992; Mark 1992] Papers at the Conferences on Spatial Information Theory (COSIT) have presented spatialized user interfaces [Chalmers 1993; Dieberger 1995; Erickson 1993; Rennison and Strausfeld 1995] This paper discusses how spatial data handling expertise applies to the spatialization of user interfaces. Section two argues why spatialization of user interfaces is useful. Steps toward a theory of spatialization are described in section three and ....

Such experience can be both instructive and enjoyable. Related research includes Darken Sibert, 1996; Dieberger, 1995; and Rennison, 1994. 2 CURRENT RESEARCH Research is being conducted in this area by the Department of Informatics at Ume University (Waterworth, 1996) This work explores tradeoffs between textual and spatial representations of information structure in virtual worlds. Specifically, how do ....

....[MDR91] Dieberger and Tromp describes a city metaphor for navigation in information spaces like hypertext [DT93] Hypertext documents are visualised as houses; link enactment as a subway system. A textual, adventure game like, approach for spatialisation of the World Wide Web is described in [Die95] A more abstract approach is spatial hypertext [MI96, MIC94] Instead of the traditional node link model, visual symbols, which are references to contentholding entities, are arranged spatially. Alignment and colours of symbols can effectively be used to indicate their relations. 9 Discussion ....

....the portion of the overall structure visible from a particular point. Effective view traversal, then, requires small view and short paths (small diameter) in the view graph. During design, inefficiently viewtraversable structures may be improved by adding a traversable infrastructure (c.f. 15] [24], 83] Furnas defines a link s to set as the targets to which the link leads efficiently; an inferred to set is a link s apparent to set. A node s outgoing link information is defined to be well matched if the node s to set matches its inferred to set with respect to all possible targets. A ....

....workspace [15] This section will discuss additional research that enhances complex information spaces with navigable, spatial presentations. Adopting a hybrid approach for physical and semantic structures, Dieberger developed a prototype that combines textual VR with a Web browser ( 23] [24]) He proposes that spatial UI metaphors facilitate user navigation in hypertext, by introducing location, distance, and direction. Dieberger s Juggler system is a so called multi user dungeon, object oriented (MOO) Derived from online text adventure games, MOOs 41 feature information ....

....Users easily lose orientation even in small hypertexts. This has been called the getting lost in hyperspace problem. It is not a shortcoming of the hypertext concept so much as it is the failure of the hypertext s user interface to communicate the structure of the information to the user [14]. Users map from the information space s structure and their tasks to navigational activities. This mapping is impossible without apparent structure. This becomes apparent in the key questions of (information) navigation [12] Is there a piece of information with the property X . How do ....

.... sometimes called MOOs (Multi User Dungeon Object Oriented) are multi participant virtual environments in which locations, objects, users and even activities are described by text only [7, 10, 11, 17] Textual virtual environments can be used to experiment with spatial metaphors as was described in [14, 15]. The text only representation allows us to realize parts of the metaphor that are difficult to realize graphically. Although metaphors are independent of their representation, most users will find a textual representation more difficult to get used to than a well designed graphical ....

....that can structure a large information space into smaller consistent regions and thus make navigation effective even in very large systems. A careful design of magic features allows users to use the spatial framework provided by the spatial metaphor and still understand the shortcuts provided [16, 32]. 4. The Information City motivation and basic concepts The Information City is a conceptual spatial user interface metaphor for large information spaces. It is based on structures found in real cities, on knowledge of city planning and on how people learn such environments. The city is a rich ....

....in a Web directory or many hot lists. Although many Web directories are companies that finance themselves by placing advertisements on their search pages these directories essentially still are a version of social navigation because they act as structure providers for other users as described in (Dieberger 1995). The interesting and very special aspect of these types of navigation is that they are services that are essentially provided for free. In most cases people do not have personal profit from providing a pointer page except that they may be known to other people on the Web, which is mainly a ....

....people on the Web, which is mainly a social aspect of having a Web presence. 2.1. Navigation needs structure An interesting aspect of pointer pages be they search engines or personal pointer pages is that they are a way to provide structure for an essentially unstructured information space (Dieberger 1995). With the ongoing growth of the World Wide Web the expression lost in hyperspace, traditionally used to describe navigation problems in hypertext systems, has become popular again. The Web has reached a size that makes it almost impossible to quickly locate information on it. A lot of useful ....

....Each level contains departments which contain URLs related to one topic. The interior of departments can be arranged either using sub departments, or using hallways. These hallways ideally would be built such that more detailed information is provided the farther one navigates into the department [8]. Inside the departments non spatialized objects like presentations and bookshelves are placed. Architectural metaphors lend themselves to holding related information together. On a higher level buildings, districts and cities can be constructed to form more complex information structures ....
