Key challenges in application and content scheduling for Open Pervasive Display Networks

Abstract

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 domain are set to change radically. For example, we envision that displays in our environment will soon be able to adapt to their surroundings and allow viewers to appropriate them by actively selecting and/or contributing content. Such levels of interactivity and context-awareness will require new approaches to content scheduling. In this paper we discuss the challenges faced in developing new forms of application and content scheduling for Open Pervasive Display Networks.
