As a number of sociologists and philosophers have pointed out, past social interaction, as well as past use of the heterogeneous mix of media, tools and artifacts that we use in our everyday activity, influence our ongoing interaction with the people and media at hand. We suggest that the past is thus part of one’s current context, and can be seen as combining and interweaving the temporal and subjective patterns of individuals’ use of heterogeneous media as well as objectively structured representations of individual media. Based on this theoretical discussion, we present a number of critiques and suggestions for systems design approaches that reflect this historical aspect of context, and which make good use of the past in supporting ongoing user activity. </ABSTRACT></RECORD></RECORDS></XML>
