The key challenge for designers of future display systems will be to create innovative new systems that deliver real value to passersby. The research presented in this issue showcases some of the challenges--and potential solutions--in making pervasive displays more useful and user-friendly. As new display and sensing technologies become available to better support such innovation, pervasive displays...
Today's digital signage systems typically show content that has been scheduled well in advance by their respective “owners”, i.e., companies or individuals who paid for and/or operate the public display. However, with the shift to open display networks that can obtain content from many sources and the corresponding advances in interaction and sensing technologies, the scheduling requirements in this...
Open public display networks could emerge as a new communications medium for the 21st century, but this transformation can only occur if the technology moves from its current, closed model to a new, open one.
A reflection on the authors' experiences with public display research—systems built and lessons learned—explores content creation and control, programmable infrastructures, and applications, to offer unique insights for those considering research or practical deployments using this technology.
There is increasing interest in creating networks of situated public displays that offer novel forms of interaction and rich media content—often as work towards a vision of ubiquitous computing or ambient multimedia. In this paper, we present an infrastructure developed as part of the e-Campus project that is designed to support the coordinated scheduling of rich media content on networks of situated...
