The cognitive and behavioural determinants of human movement in the built environment have been a subject of investigation by environmental researchers, cognitive psychologists as well as architects and urban planners for several decades. Human movement in the built environment can be highly faceted, depending on environmental factors and the task structure of the human agent. For example, researchers are looking at both wayfinding and free exploration of indoor as well as outdoor environments. Wayfinding can be defined as the process to navigate through a chosen route that connects an origin to a destination. It is a target-directed process that implies to determine and correctly place the starting position, identify the favourite or correct route, constantly monitor this route during the way, and properly recognize the destination when it has been reached. Any phase of this process requires the performer to read, understand, interpret, and correctly use environmental cues. To do so, travellers use various spatial, behavioural and cognitive abilities, and use several kinds of environmental cues, depending on the variety of the task, and/or on the characteristics of the navigation setting (e.g., city vs. building). For tasks with less clearly restricted goal characteristics, like free exploration of a new environment or the planning of multi-stop shopping trips in large-scale malls the interplay of environmental, cognitive and motivational factors will vary. Studies in this field have approached differently the question of how people select and read environmental cues: E.g., they focus more on social or physical characteristics of the environment, use different kinds of instruments to approach the topic through field studies or laboratory experiments, and target more social or cognitive aspects of the performance. Furthermore, this issue has been approached by different disciplines as architecture, urban planning, cognitive and environmental psychology. In fact the papers in this symposium represent contributions from these four disciplines. The symposium aims to collect studies that deepen the subject matter from different points of view. It includes contributions that investigated wayfinding both in indoor and in outdoor built environments, considering either the role of physical or social cues in aiding people to read familiar and not-familiar environments.
