“…The papers collected in this special issue on 'Awareness in CSCW' all contribute to the investigation of these issues in a variety ways, by 'unpacking' and identifying the variegated practices that have been thrown together under the label 'awareness' (Chalmers, 2002;Heath et al, 2002;Mark, 2002;Robertson, 2002); by systematic conceptual analysis of the 'elements of knowledge' at play in 'workspace awareness' (Gutwin and Greenberg, 2002); by exploring new 'sensation and interaction possibilities' offered by for instance wearable computational devices (Gaver, 2002), by studying novel mechanisms to 'produce, gather and redistribute information from everyday activities' (Fitzpatrick et al, 2002); and by exploring a radically distributed computational model of awareness based on the 'reaction-diffusion metaphor' (Simone and Bandini, 2002).…”
