Enterprise workers are increasingly becoming mobile and this is creating scenarios for anytime-anywhere collaboration, using different sets of devices, services and modalities at different times. One of the challenges is to enable seamless contextual collaborations, where people get the best possible collaboration experience at all times. This paper describes a method for generating the most appropriate view of an active collaboration context for a user, in terms of combinations of devices-media-services, using specified constraints. As the user moves from one set of devices to another, these combinations are seamlessly adapted.
