Where am I? What can I do here? Where can I go from here? Consciously or not, we ask such questions every day as we navigate the places and spaces of our lives. Whether we find ourselves in a museum, hospital, train station, park, or street in an unfamiliar city, we depend on systems of visual, audible, and tactile cues not only to lead the way, but also to keep us safe. They are the fundamental questions of wayfinding—a process that encompasses both the experience of choosing a path within a built environment and the set of design elements that aid in such a decision.
