Determining node positions is essential for many next-generation network functionalities. Previous localization algorithms lack correctness guarantees or require network density higher than required for unique localizability. In this paper, we describe a class of algorithms for fine-grained localization called <i>Sweeps</i>. Sweeps correctly <i>finitely(More)
—When adapting existing table games for the mobile setting, there is a choice of either keeping the round-based approach of such games or giving it up and optionally replacing it with additional " magical " features only available for the location-based version of the game. Based on our experience in building a hide and seek game using both approaches(More)
The introduction of pervasive computing environments in everyday life will not just be a big step for users, but also for application designers. The well defined interaction interfaces will make place for other, more intuitive ways of interaction. It is the challenge for a pervasive system middleware to capture and model the user intention in a smart way(More)
The rapid growth of mobile Internet use requires highly flexible and adaptable user interfaces for web applications. Contextual data from various sources as for example device HMI constraints, environmental information or device sensors need to be taken into account to dynamically adapt the application's UI. The same is true for web applications that are(More)
Currently,user interfaces are defined by single applications butworkflows may span multiple ones. In the result, users have to work with separated programs in parallel and deal with separated interfaces to fulfill their tasks. In desktop computing with extensive screens, working with several opened windows might not be eligible but bearable. Formobile(More)
The introduction of pervasive computing environments enforce new ways of human-machine-interaction. The welldefined interaction interfaces will make place for other, more intuitive ways of interaction. In a pervasive service environment, the system middleware should take care of capturing the user's expression of an action intention, solving ambiguousness(More)
In diesem Beitrag wird ein Ansatz zur systematischen Erstellung eines Lehrveranstaltungs-begleitenden Lernmaterials beschrieben, der seit einiger Zeit erfolgreich im Diplom-Informatik-Studiengang von der Forschungsgruppe Cooperation & Management (C&M) an der Universität Karlsruhe (TH) erprobt wurde. Beim C&M-konformen Kurs handelt es sich um eine Form von(More)
In this paper we introduce Mister X mobile, an innovative hide-and-seek game which is part of the Adaptive Mobile Gaming research project of the University of Bonn in cooperation with and funded by Deutsche Telekom. It is an adoption of the famous German board game Scotland Yard by Ravensburger Spieleverlag GmbH. Besides being a location-based mobile(More)
