Abstract: Visual and verbal communication of reliable route information depends on the identification of unique features in the environment. While current route information systems focus on easily accessible data, especially street names to achieve this goal, human navigators prefer landmarks. Everything that sticks out from the background can serve as a landmark (e.g., Presson & Montello, 1988). This simple statement offers many opportunities to employ landmarks in route information systems and location based services (LBS) beyond the current state of the art found in the literature (e.g., Elias, 2003; Raubal & Winter, 2002). What counts as background, though, is defined by the context in which the landmark identification process occurs. To highlight this point think of a radar system on a ship in dense fog: while the radar is able to detect a nearby promontory, visual systems fail. The same is true with respect to the same identification process placed in different environments: Looking at a city map and focusing on intersections only those will jump to the eye that configuratively stick out (e.g., Werner & Long, 2003). In contrast, during route following several types of intersections will be salient due to their functional role for the route as such or parts of it, like the well discussed Tintersection (Klippel, Tappe, & Habel, 2003; Mark, 1985) that blocks forward movement. This salience of spatial structures offers several opportunities to improve route direction systems in at least two aspects: (a) to allow for the identification of meaningful parts in a route (so called HORDE (Klippel, 2003)); (b) to offer a reliable alternative to the time consuming and sometimes difficult identification of street names (Tom & Denis, 2003).
