This book considers how people talk about their environment, find their way in new surroundings, and plan routes. Part I explores the empirical insights gained from research in the cognitive underpinnings of spatial representation in language. Part II proposes solutions for capturing such insights formally, and in Part III authors discuss how theory is put into practice through spatial assistance systems. These three perspectives stem from research disciplines whichdeal with the spatial domain in different ways, and which often remain separate. In this book they are combined so as to highlight both the state of the art in the field and the benefit of building bridges between methodologies and disciplines. Finding our way and planning routes is relevant to usall; this book ultimately helps improve our everyday lives.
