A public display that is able to present the right information at the right time is a very compelling concept. However, realising or even approaching this ability to autonomously select appropriate content based on some interpretation of the surrounding social context represents a major challenge. This chapter provides an overview of the key challenges involved and an exploration of some of the main alternatives available. It also describes a novel content adaptation framework that defines the key building blocks for supporting autonomous selection of the Web sources for presentation on public displays. This framework is based on a place model that combines content suggestions expressed by multiple place visitors with those expressed by the place owner. Evaluation results have shown that a place tag cloud can provide a valuable approach to this issue and that people recognize and understand the sensitivity of the system to their demands.

2. Approaches For Adaptive Content On Public Displays

The idea of a public display that is able to present the right information to the right users, at the right time and in the right way is obviously very compelling. However, realising it, or even approaching it in some way, is extremely challenging because of the complex issues involved, such as obtaining information about preferences in a non-obtrusive and privacy-preserving way, the need to combine the various preference expressions of the people in that place, and the complexities involved with making meaningful inferences about relevance based on the information available. The first major challenge however is to properly characterize the problem and its key assumptions, as a very broad range of approaches have been followed to explore different views of this problem domain. To clarify the overall design space for adaptive content on public displays, we will start with an overview of the overall scheduling principles that determine how content is selected and we will analyse how previous work has explored the different possibilities offered by that design space.
