Encouraging spectacle to create self-sustaining interactions at public displays

We present the first public trial of a novel mobile phone-public display application and discuss how key results from the trial can influence future designs of high visibility human-computer interactions. This paper describes how the design and deployment of the installation was engineered to utilise the single user's interaction, both to attract participants and onlookers as well as to sustain a continuous flow of new participants. We present a series of significant ethnographic observations relating to the public's interaction with the installation during its use then discuss how these features contributed to the success of the installation's original aims and how observations of unexpected behaviour offer insight into design strategies that can be employed to foster the role of participant as a crucial aspect of the overall spectacle.
