Runtime support for a dynamically composable and adaptive wearable system

We present a versatile personal system comprisingwearable and portable devices communicating via short-rangeradio. The system can be composed in an ad-hocfashion, by bringing individual devices in proximity witheach other. As a consequence it is possible for the user tobuild the desired system for a given task at hand in astraightforward way, via physical movement and withoutissuing any explicit configuration commands. System andapplications adapt their behavior as a function of theresources provided by the devices that are part of thecurrent system configuration. We give an overview of theruntime support provided to promote development in thishighly dynamic setting, with particular focus on adaptivemanagement of storage and user interface resources.
