Four Stages of User Activities

In: Interact '84 Conference Papers, vol. 1, pp. 81-85, IFIP.

Abstract

The interaction between a person and a computer system involves four different stages of activities—intention, selection, execution, and evaluation—each of which may occur at different levels of specification. Analysis of these stages and levels provides a useful way of looking at the issues of human-computer interaction.

"The library is not a shrine for the worship of books. It is not a temple where literary incense must be burned or where one's devotion to the bound book is expressed in ritual. A library, to modify the famous metaphor of Socrates, should be the delivery room for the birth of ideas - a place where history comes to life." — Norman Cousins, 1954
