    Although Cloud Computing promises to lower IT costs and increase users' productivity in everyday life, the unattractive aspect of this new technology is that the user no longer owns all the devices which process personal data. To lower scepticism, the project SensorCloud investigates techniques to understand and compensate these adoption barriers in a scenario consisting of cloud applications that utilize sensors and actuators placed in private places. This work provides an interdisciplinary overview of the social and technical core research challenges for the trustworthy integration of sensor and actuator devices with the Cloud Computing paradigm. Most importantly, these challenges include i) ease of development, ii) security and privacy, and iii) social dimensions of a cloud-based system which integrates into private life. When these challenges are tackled in the development of future cloud systems, the attractiveness of new use cases in a sensor-enabled world will considerably be increased for users who currently do not trust the Cloud.Comment: 14 pages, 3 figures, published as technical report of the Department of Computer Science of RWTH Aachen Universit

    Science and Engineering of Cyber-Physical Systems (Dagstuhl Seminar 11441)

    No full text
    Today, a new category of engineering systems is emerging that combines the physical with the computational in a holistic way: Cyber-physical systems (CPS). The key property of these systems is that functionality and salient system properties are emerging from an intensive interaction of physical and computational components. Traditional separation along engineering disciplines in the design of such systems leads to various quality, maintainability and evolutionary problems, and integrated theories and engineering techniques are urgently needed. The purpose of the seminar is to bring together researchers from the field, from both academia and industry to discuss the new scientific foundations and engineering principles for the vastly emerging field of CPS

    The International Conference and Research Center for Computer Science is a non-profit organization. Its objective is to promote world-class research in computer science and to host research seminars which enable new ideas to be showcased, problems to be discussed and the course to be set for future development in this field. The work being done to run this informatics center is documented in this report for the business year 2011

    SiAM-dp : an open development platform for massively multimodal dialogue systems in cyber-physical environments

    Cyber-physical environments enhance natural environments of daily life such as homes, factories, offices, and cars by connecting the cybernetic world of computers and communication with the real physical world. While under the keyword of Industrie 4.0, cyber-physical environments will take a relevant role in the next industrial revolution, and they will also appear in homes, offices, workshops, and numerous other areas. In this new world, classical interaction concepts where users exclusively interact with a single stationary device, PC or smartphone become less dominant and make room for new occurrences of interaction between humans and the environment itself. Furthermore, new technologies and a rising spectrum of applicable modalities broaden the possibilities for interaction designers to include more natural and intuitive non-verbal and verbal communication. The dynamic characteristic of a cyber-physical environment and the mobility of users confronts developers with the challenge of developing systems that are flexible concerning the connected and used devices and modalities. This implies new opportunities for cross-modal interaction that go beyond dual modalities interaction as is well known nowadays. This thesis addresses the support of application developers with a platform for the declarative and model based development of multimodal dialogue applications, with a focus on distributed input and output devices in cyber-physical environments. The main contributions can be divided into three parts: - Design of models and strategies for the specification of dialogue applications in a declarative development approach. This includes models for the definition of project resources, dialogue behaviour, speech recognition grammars, and graphical user interfaces and mapping rules, which convert the device specific representation of input and output description to a common representation language. - The implementation of a runtime platform that provides a flexible and extendable architecture for the easy integration of new devices and components. The platform realises concepts and strategies of multimodal human-computer interaction and is the basis for full-fledged multimodal dialogue applications for arbitrary device setups, domains, and scenarios. - A software development toolkit that is integrated in the Eclipse rich client platform and provides wizards and editors for creating and editing new multimodal dialogue applications.Cyber-physische Umgebungen (CPEs) erweitern natĂŒrliche Alltagsumgebungen wie Heim, Fabrik, BĂŒro und Auto durch Verbindung der kybernetischen Welt der Computer und Kommunikation mit der realen, physischen Welt. Die möglichen Anwendungsgebiete hierbei sind weitreichend. WĂ€hrend unter dem Stichwort Industrie 4.0 cyber-physische Umgebungen eine bedeutende Rolle fĂŒr die nĂ€chste industrielle Revolution spielen werden, erhalten sie ebenfalls Einzug in Heim, BĂŒro, Werkstatt und zahlreiche weitere Bereiche. In solch einer neuen Welt geraten klassische Interaktionskonzepte, in denen Benutzer ausschließlich mit einem einzigen GerĂ€t, PC oder Smartphone interagieren, immer weiter in den Hintergrund und machen Platz fĂŒr eine neue AusprĂ€gung der Interaktion zwischen dem Menschen und der Umgebung selbst. DarĂŒber hinaus sorgen neue Technologien und ein wachsendes Spektrum an einsetzbaren ModalitĂ€ten dafĂŒr, dass sich im Interaktionsdesign neue Möglichkeiten fĂŒr eine natĂŒrlichere und intuitivere verbale und nonverbale Kommunikation auftun. Die dynamische Natur von cyber-physischen Umgebungen und die MobilitĂ€t der Benutzer darin stellt Anwendungsentwickler vor die Herausforderung, Systeme zu entwickeln, die flexibel bezĂŒglich der verbundenen und verwendeten GerĂ€te und ModalitĂ€ten sind. Dies impliziert auch neue Möglichkeiten in der modalitĂ€tsĂŒbergreifenden Kommunikation, die ĂŒber duale Interaktionskonzepte, wie sie heutzutage bereits ĂŒblich sind, hinausgehen. Die vorliegende Arbeit befasst sich mit der UnterstĂŒtzung von Anwendungsentwicklern mit Hilfe einer Plattform zur deklarativen und modellbasierten Entwicklung von multimodalen Dialogapplikationen mit einem Fokus auf verteilte Ein- und AusgabegerĂ€te in cyber-physischen Umgebungen. Die bearbeiteten Aufgaben können grundlegend in drei Teile gegliedert werden: - Die Konzeption von Modellen und Strategien fĂŒr die Spezifikation von Dialoganwendungen in einem deklarativen Entwicklungsansatz. Dies beinhaltet Modelle fĂŒr das Definieren von Projektressourcen, Dialogverhalten, Spracherkennergrammatiken, graphischen Benutzerschnittstellen und Abbildungsregeln, die die gerĂ€tespezifische Darstellung von Ein- und AusgabegerĂ€ten in eine gemeinsame ReprĂ€sentationssprache transformieren. - Die Implementierung einer Laufzeitumgebung, die eine flexible und erweiterbare Architektur fĂŒr die einfache Integration neuer GerĂ€te und Komponenten bietet. Die Plattform realisiert Konzepte und Strategien der multimodalen Mensch-Maschine-Interaktion und ist die Basis vollwertiger multimodaler Dialoganwendungen fĂŒr beliebige DomĂ€nen, Szenarien und GerĂ€tekonfigurationen. - Eine Softwareentwicklungsumgebung, die in die Eclipse Rich Client Plattform integriert ist und Entwicklern Assistenten und Editoren an die Hand gibt, die das Erstellen und Editieren von neuen multimodalen Dialoganwendungen unterstĂŒtzen
