Kirsh, D. (2001). The Context of Work. Human Computer Interaction, vol. 16, pp. 305-322 [versão html / falta arranjar versão pdf c/ numeração de páginas]:
"I have been describing the context of work as a highly structured amalgam of informational, physical, and conceptual resources that go beyond the simple facts of who or what is where, when. Some of these resources are shared knowledge between participants, others have to do with the structure of the tasks a user is involved in and the different ways he or she has of coordinating the use of physical, informational and conceptual resources between himself, the work setting, and teammates."
"First, we must understand the factors which bias how people react to rich information spaces, loaded with entry points to more information. Second, we must unravel the complexities of the activity landscapes we interactively construct out of the resources we find and the tasks we have to perform. Finally, we must chart the diverse ways people coordinate their activity with their environment and with others."
