Despite huge progress in information and communication technology it is often difficult to spontaneously contact persons who are at other locations. Often important information about the persons at other sites is missing. Users need to know if the potential communication or cooperation partners are present in the system, if they are available, how busy they are, and so forth. Furthermore, users need this information independently of their current location and adapted to their current context. In this paper we introduce the PRAVTA prototype that provides users with awareness about presence, availability, and tasks of other users anytime and anyplace.
