This paper presents the development of a lightweight component model that allows user to manage the introduction and arrangement of new interactive services and devices in the home. Interaction techniques developed through userparticipation enable household members – rather than designers – to configure and reconfigure interactive devices and services to meet local needs. As part of this we have developed a tablet-based editor that discovers available ubiquitous components and presents these to users as jigsaw pieces that can be dynamically recombined. We conclude by considering the broad implications for the design of interactive domestic environments suggested by our approach.
