Fueled by falling display hardware costs and rising demand, digital signage and pervasive displaysare becoming ever more ubiquitous. Such systems have traditionally been used for advertising andinformation dissemination with digital signage commonplace in shopping malls, airports and publicspaces.While advertising and broadcasting announcements remain important applications, developmentsin sensing and interaction technologies are enabling entirely newclasses of display applicationsthat tailor content to the situation and audience of the display. As a result, signage systems arebeginning to transition from simple broadcast systems to rich platforms for communication andinteraction.In this lecture we provide an introduction to this emerging field for researchers and practitionersinterested in creating state-of-the-art pervasive display systems. We begin by describingthe history of pervasive display research, providing illustrations of key systems, from pioneeringwork on supporting collaboration to contemporary systems designed for personalized informationdelivery.We then consider what the near-future might hold for display networks—describing a seriesof compelling applications that are being postulated for future display networks. Creating suchsystems raises a wide range of challenges and requires designers to make a series of important tradeoffs.We dedicate four chapters to key aspects of pervasive display design: audience engagement; display interaction, system software and system evaluation. These chapters provide an overview ofcurrent thinking in each area. Finally, we present a series of case studies of display systems and ourconcluding remarks.    «
