We propose a mARGraphy, which visualizes information based on augmented reality (AR) technology. It provides the intuitive and interactive way to make users to understand dynamic 3D information in situ with highly relevant to the target. To show the effectiveness of our work, we introduce a traditional map viewer application. It recognizes region of a traditional map with object recognition and tracking method on a mobile platform. Then, it aggregates dynamic information obtained from database such as geographical features with temporal changes, and situational contexts. For the verification of this work, we observed how our system improves users' understanding information with mARGraphy through preliminary user study.
