The human action cycle is a psychological model which describes the steps humans take when they interact with computer systems. The model was proposed by Donald A. Norman, a scholar in the discipline of human-computer interaction. The model can be used to help evaluate the efficiency of a user interface (UI). Understanding the cycle requires an understanding of the user interface design principles of affordance, feedback, visibility and tolerance.
The human action cycle describes how humans may form goals and then develop a series of steps required to achieve that goal, using the computer system. The user then executes the steps, thus the model includes both cognitive activities and physical activities.

Famous quotes containing the words human, action and/or cycle:
“I am really sorry to see my countrymen trouble themselves about politics. If men were wise, the most arbitrary princes could not hurt them. If they are not wise, the freest government is compelled to be a tyranny. Princes appear to me to be fools. Houses of Commons & Houses of Lords appear to me to be fools; they seem to me to be something else besides human life.”
—William Blake (1757–1827)
“In the life of the human spirit, words are action, much more so than many of us may realize who live in countries where freedom of expression is taken for granted. The leaders of totalitarian nations understand this very well. The proof is that words are precisely the action for which dissidents in those countries are being persecuted.”
—Jimmy Carter (James Earl Carter, Jr.)
“Only mediocrities progress. An artist revolves in a cycle of masterpieces, the first of which is no less perfect than the last.”
—Oscar Wilde (1854–1900)
