Effectively assisting people in complex and highly dynamic work environment requires advances in high-level declarative activity models that can describe the flow of human work activities and their intended outcomes, as well as novel interaction approach for distributing and coordinating information across physical objects, time and space. This paper describes a novel modeling technique for pervasive systems based on high-level models of human activities, so-called situated flows and presents a corresponding flow driven distributed software framework. This framework provides the foundation for discovery, adaptation and execution of flows in real time matching the dynamics of real world activity and consequently drives the pervasive interaction using push interfaces to facilitate a synergic coordinated interaction experience in dynamic work environments.
