Abstract
Spatial user interface metaphors are assumed to improve navigation in large information spaces. In this article we will review some of the spatial user interface metaphors that have been introduced. Especially one of those - the city metaphor - depends heavily on real world navigation skills.
To find out how users actually perceive and navigate large information spaces using a city metaphor the very popular networked game Multi User Dungeon (MUD) has been selected for further study. MUD environments normally support adventure gaming but the potential of MUDs as collaborative environments and discussion fora has been recognized already by researchers and user interface developers. Some of this research is shortly summarized. The design and results of two electronic questionnaires about navigational behaviour and spatial perception conducted in a MUD are discussed in more detail. Results indicate that users have no problem with navigation or the development of a cognitive map of the information space, but that teleportation, one of the modes of transportation, and magic mazes, some special kind of rooms can be very confusing. Advise is given about the implementation of a MUD as an information browser.
