The paper describes the idea of bringing awareness to nomadic users. Based on a discussion of different context models and approaches to model context, several scenarios for awareness in context-aware systems are presented. We describe the combination of a context aware guidance system and an awareness platform to enable awareness for nomadic users about other users that are either in a similar electronic of spatial context. This could enhance the communication and interaction facilities for nomadic users by localisation, user modelling and an awareness platform to monitor state and events of the electronic and the physical environment.
