Many human activities follow a loosely defined script in which individuals assume roles. Encoding such scripts in a formal representation makes it possible to build systems that observe and understand human activity. In this paper, we first present a conceptual framework in which scripts for human activity are described as scenarios composed of actors and objects within a network of situations. We provide formal definitions for the underlying concepts for situation models, and then propose a layered, component-based, software architecture model for constructings systems to observe human activity. Both the conceptual framework and architectural model are illustrated with a system for real-time composition of a synchronized audio-video streams for recording activity within a meeting or lecture.

“…In the case of workflow in science and engineering, the primary topic of the papers here, workflow concepts have evolved from distributed programming using systems such as Linda [3], AVS [4] and Khoros [5] and complex shell scripts to a suite of sophisticated programming systems described below. Similarly, the Grid world has evolved from simple toolkits to authenticate users on remote supercomputers, to a service-based architecture intended for activities ranging from supporting large, distributed virtual organizations for e-science to autonomic and on-demand computing for commercial enterprises.…”

Abstract. Human activity is extremely complex. Current technology allows us to handcraft real-time perception systems for a specific perceptual task. However, such an approach is inadequate for building systems that accommodate the variety that is typical of human environments. In this paper we define a framework for context aware observation of human activity. A context in this framework is defined as a network of situations. A situation network is interpreted as a specification for a federation of processes to observe humans and their actions. We present a process-based software architecture for building systems for observing activity. We discuss methods for building systems using this framework. The framework and methods are illustrated with examples from observation of human activity in an "Augmented Meeting Environment".
