PosterPointing

Abstract

In this paper we explore the potential for creating large pseudodisplays using posters instead of touchscreens. Interactive public displays are common in city centres, but may not be accessible to emergent users. However, the prevalence of increasingly smart, sensor-rich mobile devices offers an alternative. The PosterPointing concept uses physical gestures with mobile devices around printed media in order to explore a rich set of interactions. We created a prototype to investigate the feasibility of one method of enabling this, and suggest other potential approaches. We performed a study to understand how emergent users might gesture using a small device to interact with two larger surface scenarios. Our results show a range of gestures and combinations of phone and paper surface, and offer suggestions for how the design might be used in future.
