No artigo “The Three Paradigms of HCI“, entre outras coisas, vem uma brevissima história desta ciência.

“The first paradigm, an amalgam of engineering and human factors, saw interaction as a form of man-machine coupling in ways inspired by industrial engineering and ergonomics. The goal of work in this paradigm, then, is to optimize the fit between humans and machines; the questions to be answered focus on identifying problems in coupling and developing pragmatic solutions to them. Occupying the center of the first paradigm are concrete problems that arise in interaction and cause disruption; at the margin are phenonema that underlie interaction but do not directly lead to noticeable trouble.”

“The second paradigm, in contrast, is organized around a central metaphor of mind and computer as coupled information processors. At the center is a set of information processing phenomena or issues in computers and users such as ‘how does information get in’, ‘what transformations does it undergo’, ‘how does it go out again,’ ‘how can it be communicated efficiently’ and so forth.”

“Left at the margin are phenomena that are difficult to assimilate to information processing, such as those that admit of variation and multi-causal explanation including how people feel about interaction, the place of a particular interaction in larger systems of use, and elusive and enigmatic aspects of everyday life such as “what is fun?”.”
