Creating, Editing, and Sharing Complex Ubiquitous Computing Environment Configurations with CollaborationBus
Tom Gross, Nicolai Marquardt · 2001
Abstract. 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 congure Ubiquitous Computing environments. We introduce the CollaborationBus application: a graphical editor that provides abstractions from base technology and thereby allows multifarious users to congure Ubiquitous Computing environments. By composing pipelines users can easily specify the information ow from selected sensors via optional lters for processing the sensor data to actuators changing the system behaviour according to their 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 ows through their pipelines. In this paper we present the concept, implementation, and user interface of the CollaborationBus application. Key words: ubiquitous computing; editor; conguration 1. Introduction. The
