Abstract
We present an in-the-wild user study (n=27) investigating the combination of two mobile technologies – picoprojectors and marker based information browsing. We studied a tour, where the tour guide used combinations of fixed and projected elements to present information, and compare four cases: A) as a baseline, a traditional paper poster, B) a projected poster, C) a printed paper fiducial marker, viewed through a mobile device browser application, and D) a projected fiducial marker viewed through a mobile device browser application. As a contribution, we present a novel approach to ad hoc projection of markers, and the findings of the user study. Here, the salient findings suggest that the techniques using markers have the potential to enhance the tour participants’ engagement with the tour guide, attention, group cohesion and responsiveness to contextual factors, but face practical challenges due to lighting conditions and image stability.
