    The AR-Marker in the Urban Space
    (Mensch und Computer 2019 - Workshopband, 2019) Nestler, Simon; Pranz, Sebastian; Neuburg, Klaus
    When considering the role of Augmented Reality (AR) in the urban space, most previous work is focusing on touristic and everyday life use cases. However, the project “Archäologie der Gegenwart” which we present in this paper illustrates the different aspects of change in Hamm during the last 50 years. Thus, our AR approach opens up a deeper understanding of the urban cultural change processes by the means of AR. Our considerations lead to adding an AR layer as a fifth social dimension in the urban space. Technically, we robustly link this fifth layer with the existing topography by marker-based tracking with six degrees of freedom (6 DOF). When building AR applications for the urban space, the deeper understanding of the marker paradigm is crucial: During our workshops we identified and analyzed seven requirements for the utilization of markers in the public urban space. Additionally, we analyzed the general AR marker paradigm from the human-computer interaction (HCI) perspective by considering the affordances and signifiers of the marker objects themselves, analyzing the tracking technology and summarizing the marker’s role for past, present and future AR applications. Thus, the role of the AR marker is twofold: On the one hand the marker is part of the 6 DOF tracking technology, on the other hand it makes AR layers perceivable in the urban space. We expect that the importance of these markings for guiding citizens through AR experiences will emerge in urban spaces, whereas the role of markers for technical tracking purposes will decrease.

    Visualization and Interaction with Multiple Devices. A Case Study on Reachability of Remote Areas for Emergency Management
    (i-com: Vol. 16, No. 3, 2017) Tost, Jordi; Heidmann, Frank
    When a hazard event strikes, the reachability of affected areas is a significant factor that can determine if the situation becomes a disaster. Decision makers have to react quickly while under stress to tasks that depend on the road network, such as management of relief operations, planning of evacuation routes, or food and first aid distribution. In this paper we present an approach for exploring and validating reachability of remote areas through visualization with an interactive tabletop and tablets. We propose a simple way to combine and visualize data from scientists and communities to provide insights into area reachability, as well as the likely impacts of future hazard events on access routes. Moreover, our interface introduces an approach to assess alternative accessibility options to isolated settlements by helicopter or off-road routes that builds on satellite data and interactive collaborative mapping. This set of visualization and interaction techniques facilitates the formation of risk scenarios for better planning, preparedness and response activities. We developed our research with a case study of landslide threat for an area in Colombia.
