Space-aware TeC: End-user development of safety and control systems for smart spaces

This paper presents team computing, TeC, a framework for end-user design, deployment, and evolution of applications for ubiquitous computing. Systems in TeC act as teams of elements with no central control: elements play their roles autonomously, and system behavior is emergent. The paper presents five small but illustrative systems in the domains of home automation, energy management, and surveillance. TeC´s features include the ability to relate, at the design level, system behaviors to physical location and to the presence and identity of users. TeC also allows for the secure integration of parts of design contributed by different users. The paper discusses the implementation of a software infrastructure for the design and automated deployment of systems.
