In recent decades, communication media have made strides in enabling efficient and effective communication and collaboration. An increasing range of media are available providing a lot of the richness of human-human communication when this is mediated. The increased availability of such media communication media and the increasingly continuous connectivity of individuals can have fundamental impact on the way we work together with colleagues, or the way we socialize with friends and family. Individuals can initiate contacts opportunistically and with great ease, which at the receiving end creates the problem of managing one's availability for communication [1-3]. This need is manifested at work, where one has to avoid interrupting or being interrupted for the sake of productivity, reduced stress, and even for avoiding erroneous action; it is also manifested at leisure when individuals need to secure moments of leisure, relaxation, or private enjoyment alone or with family and friends [4-6]. The subject of availability and interruptions management has been broadly discussed in the fields of Human Computer Interaction and its subfield of Computer Supported Cooperative Work [7-11]. Although some efforts have been made to enable people to deal with multiple streams of communication, the actual problem of availability management over communication media remains unsolved and the ways in which our future workplace and our social life will be impacted are still effervescent fields of research.
It has become clear that a purely technologically-oriented approach to resolve these challenges issue is insufficient.Technology on its own seems to be unable to mimic the complexity of human communicative choices [6, 12]. A new approach emerges that aims to inform the design of communication media leveraging on extant social skills of people to manage communications [5, 13].
The articles in this special issue contribute in the body of knowledge related to this approach. Through a number of experimental and empirical studies the meaning of availability and communication management is revisited. Different user requirements pertaining to their informational and social needs are discussed and a new directions for future research are presented.
Curtis and Janssen study challenges and opportunities for supporting one's ability to stay connected and up-to- date with colleagues at work. Their study focuses on the communication needs of mobile workers examining the constructs of staying ‘in-sync’ and ‘in-touch’ with colleagues or in other words to be up to date and to feel connected to them. They particularly focus on determining the requirements of one subgroup of mobile workers: Traditionalists for whom a transition from predominately co-located interactions to those technologically-mediated seems to be most difficult. They suggest a number of technological improvements that could effectively support these people in their attempts to stay in sync and in touch with colleagues....
