This need for information disclosure often conflicts with the users' wishes for privacy. In the literature often reciprocity is suggested as a solution to this trade-off. Yet, this conception of reciprocity and its enforcement by systems does not match reality. In this paper we present our study's major findings investigating the role of reciprocity among which we found that participants greatly disregarded the above conception. Additionally we discuss their significant implications for the design of systems seeking to disclose personal information. 2006 urn:nbn:de:gbv:wim2-20111215-7474 10.25643/bauhaus-universitaet.747 Professur Computergestütztes kooperatives Arbeiten OPUS4-746 Bericht Gross, Tom; Marquardt, Nicolai CollaborationBus: An Editor for the Easy Configuration of Complex Ubiquitous Environment Early sensor-based infrastructures were often developed by experts with a thorough knowledge of base technology for sensing information, for processing the captured data, and for adapting the system's behaviour accordingly. In this paper we argue that also end-users should be able to configure Ubiquitous Computing environments. We introduce the CollaborationBus application: a graphical editor that provides abstractions from base technology and thereby allows multifarious users to configure Ubiquitous Computing environments. By composing pipelines users can easily specify the information flows from selected sensors via optional filters for processing the sensor data to actuators changing the system behaviour according to the users' wishes. Users can compose pipelines for both home and work environments. An integrated sharing mechanism allows them to share their own compositions, and to reuse and build upon others' compositions. Real-time visualisations help them understand how the information flows through their pipelines. In this paper we present the concept, implementation, and early user feedback of the CollaborationBus application. 2006 urn:nbn:de:gbv:wim2-20111215-7463 10.25643/bauhaus-universitaet.746 Professur Computergestütztes kooperatives Arbeiten OPUS4-744 Bericht Gross, Tom; Egla, Tareg; Marquardt, Nicolai Sens-ation: A Service-Oriented Platform for Developing Sensor-Based Infrastructures In today's information society the vast technical progress and the sinking cost of information and communication technology provide new opportunities for information supply, and new technical support for communication and cooperation over distance. These trends also entail challenges such as supplying information that is adequate for a particular person in a specific situation as well as managing communication among geographically distributed parties efficiently. Context-aware systems that use sensors in order to analyse their environment and to adapt their behaviour. Yet, adequate tools for developing sensor-based infrastructures are missing. We have designed and developed Sens-ation, an open and generic service-oriented platform, which provides powerful, yet easy-to-use, tools to software developers who want to develop context-aware, sensor-based infrastructures. The service-oriented paradigm of Sens-ation enables standardised communication within individual infrastructures, between infrastructures and their sensors, but also among distributed infrastructures. On a whole, Sens-ation facilitates the development allowing developers to concentrate on the semantics of their infrastructures, and to develop innovative concepts and implementations of context-aware systems. 2006 urn:nbn:de:gbv:wim2-20111215-7447 10.25643/bauhaus-universitaet.744 Professur Computergestütztes kooperatives Arbeiten
