Evaluating BluScreen: Usability for Intelligent Pervasive Displays

Within a ubiquitous environment, market-based approaches can be used to select the most appropriate material for a public display, depending on factors such as the audience's preferences and diversity of interest. Likewise, strategies used by agents to compete for customer attention should strive to be rational, based on contextual observations of user-preferences within the local environment and include a reward mechanism based on audience responses. But while such systems currently exist, utilizing Bluetooth-enabled mobile phones to uniquely identify and detect the presence of individuals within a localised environment, there is little known about their effectiveness, or even how to assess usability for these systems. In this paper, we present the details a user study that contributed to the development of an interaction model that supports a structured methodology for evaluating intelligent pervasive displays.
