Dominant approaches in computer-assisted wayfinding support adhere to the deeply problematic principles of turn-by-turn navigation. We suggest a new approach called “Wayfinding Through Orientation” which supports the acquisition of spatial knowledge and cognitive mapping for advancing the user’s spatial orientation. To visualize instructions of orientation navigation systems, we suggest to (i) select relevant landmark, route and survey information and (ii) visualize this information in schematic maps. The schematization faces two challenges: First, the schematization of routes might conflict with the schematization of survey information (e.g. a street network). Second, point-like or regional landmarks need to be placed topologically correct w.r.t. the survey information, but also in a correct spatial relation w.r.t. the route.
Landmarks in wayfinding: a review of the existing literature
Cognitive Processing
Landmarks are accepted as one of the vital elements in both virtual and real environments during wayfinding tasks. This paper provides an overview of the existing literature on the selection of landmarks in wayfinding mostly in large-scale urban environments and outdoors by discussing two main aspects of landmarks: visibility and salience. Environments and layouts used in previous studies, different tasks given to people and the main findings are explained and compared. Summary tables are created from these findings. The review concludes that there is mostly a consensus on the selection of landmarks, when considering their location. Accordingly, landmarks on route and also at decision points (with a turn) are more effective during wayfinding tasks. However, visibility of landmarks as well as visual and cognitive saliency need to be further investigated using different environments, tasks or different levels of familiarity with environments.
