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.
