Visualization and Communication of Indoor Routing Information

In this paper we investigate the display and communication of indoor routing instructions via small maps, map-like graphics and non-photorealistic presentations of interior spaces. Our goal is to elaborate on questions like, “how can we provide an optimal depiction of the navigation information so that the user is able to find the destination within an indoor environment? The destination could be for example a classroom or a particular office in a university environment. We provide a case study for indoor routing maps within the Technical University Munich’s main building. Currently available data on floor footprints, points of interests (POIs), indoor-landmarks and the routing graph for the building are used to implement a routing service. The routing information is displayed on a smart phone implemented in the Windows 7.8 operating system. Designs of different ways to display routing instructions on smart phone displays are investigated. Experiences for building up the map design for this particular indoor routing system can be transferred to other buildings and provide a basis for the design ideas of indoor routing maps.
