In this paper, we present a novel interaction technique -- combining mobile projection and visible, fiducial marker based information display. We envision it to be suitable for small groups e.g. for narrative playful experiences and for guiding in places where physical tags would be disturbing. This interaction technique, where one person (the guide) is projecting a marker and other users can read it with their mobile devices, enables in situ information delivery where the guide can control the dynamics of the situation. We present an example use case of using the interaction technique on a guided tour, and preliminary results from the user evaluation.
