In our daily life we are surrounded by posters advertising brands, products, and events. Seeing an interesting poster we often want to access related digital information and ser-vices, such as a ticket service, reviews, and opening hours. The easiest solution today is to open a browser and type in the URL printed on the poster or use a search engine to find related content. In this paper we present a system that enables the user to shoot a photo of a poster using a mobile phone. The photo is analyzed and the user receives related information and services. We compare this inter-action technique with the facility provided by recent PDAs. Our evaluation with 46 participants shows that the designed interaction outperforms a virtual keyboard based interaction in terms of speed and user satisfaction. 1.
