Public and situated display technologies can have an important impact on individual and social behaviour and present us with particular interesting new design considerations and challenges. While there is a growing body of research exploring these design considerations and social impact this work remains somewhat disparate, making it difficult to assimilate in a coherent manner. This book brings together the perspectives of key researchers in the area of public and situated display technology. The chapters detail research representing the social, technical and interactional aspects of public and situated display technologies. The underlying concern common to these chapters is how these displays can be best designed for collaboration, coordination, community building and mobility. Presenting them together allows the reader to examine everyday display activities within the context of emerging technological possibilities.
