Human-computer interaction - Whence and whither?

In this article, an overview is presented of the growth of work in Human-Computer interaction (HCI) over the last 40 years. Inevitably much must be omitted, hut the referenced papers may fill some of the gaps. Various formative influences and contributing disciplines are noted. Aspects of research and human factors knowledge are prominent, but attention is also given to technology, applied problems, and design for usability. Finally, after summarizing the growth in three age-group partitions, some of the major threads of development are noted under the heading of continuities from the past and perspectives into the future.
