Who's that girl? Handheld augmented reality for printed photo books

Published on

Augmented reality on mobile phones has recently made major progress. Lightweight, markerless object recognition and tracking makes handheld Augmented Reality feasible for new application domains. As this field is technology driven the interface design has mostly been neglected. In this paper we investigate visualization techniques for augmenting printed documents using handheld Augmented Reality. We selected the augmentation of printed photo books as our application domain because photo books are enduring artefacts that often have online galleries containing further information as digital coun-terpart. Based on an initial study, we designed two augmentations and three techniques to select regions in photos. In an experiment, we compare an aug-mentation that is aligned to the phone's display with an augmentation aligned to the physical object. We conclude that an object aligned presentation is more us-able. For selecting regions we show that participants are more satisfied using simple touch input compared to Augmented Reality based input techniques.
