The rapid diffusion of interaction technologies such as the mobile phone, email and instant messaging paralleled by a trend of mobilisation of people, information and physical objects is creating unprecedented contexts for interaction and collaboration. Whilst much of the debate focuses on the anonymous collective advantages of this development, it brings significant implications for the individual. This increased connectedness might well be a problem as well as an asset. If you can reach the rest of the world simply by pushing a button, then they can just as easily reach you by pushing one of their buttons. Much of the way in which we perceive point-to-point communication is based on the notion of reciprocity. If our attention is limited, then managing attention towards others is clearly an issue. Instantaneous availability wherever and whenever you are to others' desire for interaction may lead you to experience being overloaded. This talk will explore, by means of theoretical arguments and empirical evidence, pertinent aspects of continuous connectivity and availability.
