Ubiquitous display environments are public spaces with various situated public displays. These displays are intended to provide relevant information to people in their vicinity, where these may include the regular inhabitants of the space as well as visitors. Their nature makes the development of such displays a multidisciplinary task that combines technological with aesthetic, sociological, and legal aspects. Research usually focuses on specific aspects while neglecting others, since it is intended to explore only a limited part. Here we try to take a step back and portray the big picture, showing how various aspects need to be addressed and integrated in order to support us in today's and tomorrow's ubiquitous display environments.
