Ways of guiding people from a given location to specific other locations are discussed. Different classes of wayfinding tasks are distinguished. Various parameters that influence the suitability of
certain wayfinding aids for specific wayfinding tasks are identified. Maps are compared with verbal route descriptions and the respective advantages of the two wayfinding aids are discussed. Spatially
presented wayfinding aids, specifically schematic maps, are considered in more detail. The question of how to decide on a suitable level of abstraction for map representations is addressed. Different
ways of simplifying wayfinding are considered. An approach to systematic investigation and design of wayfinding systems is proposed. |
