    Adaptive Indoor Navigation for the Blind
    (INFORMATIK 2008. Beherrschbare Systeme – dank Informatik. Band 1, 2008) Gehring, Sven
    In this paper, we describe a prototype of an adaptive indoor navigation system which is based on mobile devices and navigates visually impaired people through an unknown building. The system determines the users position inside the building on the basis of a map of the building with the help of Bluetooth-beacons. Since an exact navigation is necessary for navigating visually impaired people, we show how the system uses landmarks for gaining a higher precision for the navigation instructions for the users. We show how the system is able to determine the maximal achievable accuracy in localizing users in the given infrastructure and how the system adapts the navigation to the accuracy.

    Interaction with Media Façades
    (Informatik-Spektrum: Vol. 37, No. 5, 2014) Gehring, Sven; Wiethoff, Alexander
    Media façades are a prominent example of the digital augmentation of urban spaces. They denote the concept of turning the surface of a building into a large-scale urban screen. Because of their enormous size, they require interaction at a distance and they have a high level of visibility. Additionally, they are situated in a highly dynamic urban environment with rapidly changing conditions, which results in settings which are neither comparable, nor reproducible. Altogether, this makes the development of interactive media façade installations a challenging task.
