We designed a 3D mobile interaction technique that utilizes mobile devices as 3D user interfaces to facilitate the use of the user’s natural skills to control public displays. To achieve this, we provide three layers of interaction, where users can see and share content at the same time. Another feature of our user interface is that it provides different tools for information seeking, such as new content creation. In this paper we present a study that examined how these tools were being used in three different scenario-based case studies. The results of this study indicate that participants found these tools useful.
