Wayfinding in a complex setting with less than perfect knowledge requires decision making under uncertainty and we aim to identify the behaviors and strategies that people employ to navigate in such environments. The level of information available to the wayfinding person might be a key contributor and we are investigating if the standard wall-mounted floor maps found in most public buildings can help to properly navigate in a complex little-known environment.
This experiment investigated the role of expertise, map usage and in-struction on wayfinding strategies, tactics and performance. 32 participants had to find eight goals in a multilevel building consisting of two distinctive parts. Their verbalizations and performance were recorded with a camera. Experts showed clearly better performance whereas maps did not improve performance. If anything, participants performed worse. The hierarchical strategies of reaching the correct building part first versus reaching the correct floor first were mainly applied according to task affordances and instruction. In accordance with the architectural structure of the building, changing the building first led to better performance. A systematic search for the goal in the correct floor showed at least as good a performance as using maps
