Abstract

A Collaborative User Experience Technical Report: more about CUE...

Contextual collaboration services seamlessly integrate existing groupware technologies into a single consistent interaction model. This model is usually implemented by a contextual collaboration infrastructure that needs to efficiently cope with the fast switching between different modes of interaction. This paper introduces a new model for contextual collaboration based on the notion of generic shared objects. We describe a native implementation of this model and evaluate its behavior under different traffic condi-tions. We also explore an alternative implementation of the col-laboration model integrating existing notification and meeting servers to deliver the same model behavior. We discuss trade-offs and limitations of those two implementations.
