Managing private user models and shared personas

Abstract

This paper explores the question: How should we modify and extend existing UM Languages and representations to address specific ubiquitous computing issues? The answer we propose builds upon previous work on single user model server and exploits the user model representation to enable users to permit parts of the environment to access selective personas, which allow the user to provide one persona to one application and a different persona to another. We discuss the way that sensors can contribute to the user model in an ubiquitous computing environment. We also describe the ways that we address the issues of reusability and group models in ubiquitous computing.
