COMMUNICATING MULTILEVEL EVACUATION CONTEXT USING SITUATED AUGMENTED REALITY

Abstract. Emergency preparedness is a fundamental component of a successful emergency management strategy. This includes a proactive communication strategy that informs all stakeholders of the emergency plan and helps translate that knowledge to real spaces. Communicating multilevel built environments can be difficult, as the architectural complexity creates problems for both visual and mental representations of networks in 3D space. Modern mobile technology offers emerging opportunities for emergency managers to develop and deploy 3D visualizations of multilevel spaces that preserve the topology of those spaces while adding the spatial context that allows the individual to better understand their position within it. In this paper, we present a collection of mixed reality (specifically augmented reality) geovisualizations that overcome the visual limitations associated with the traditional static 2D methods of communicating the evacuation plans of multilevel structures. We demonstrate how this technology can provide spatially contextualized 3D geovisualizations that promote spatial knowledge acquisition and support cognitive mapping. These geovisualizations are designed as a proactive emergency management tool to educate and prepare at risk populations prior to the occurrence of a hazardous event.
