Abstract. We describe an interaction technique for controlling site-specific mobile services using commercially available camera-phones, public information displays and visual tags. We report results from an experimental study validating this technique in terms of pointing speed and accuracy. Our results show that even novices can use camera-phones to “point-and-click” on visual tags quickly and accurately. We have built a publicly available client/server software framework for rapid development of applications that exploit our interaction technique. We describe two prototype applications that were implemented using this framework and present findings from user-experience studies based on these applications.
