History
The field of cognitive ergonomics emerged predominantly in the 70's with the advent of the personal computer and new developments in the fields of cognitive psychology and artificial intelligence. CE contrasts the tradition of physical ergonomics because "cognitive ergonomics is...the application of psychology to work...to achieve the optimization between people and their work." Viewed as an applied science, the methods involved with creating cognitive ergonomic design have changed with the rapid development in technological advances over the last 27 years. In the 80's there was a worldwide transition in the methodological approach to design. According to Enid Mumford was one of the pioneers of interactive systems engineering, and advocated the notion of user-centered design, wherein the user is considered and "included in all phases of the design". There are several different models which describe the criteria for designing user-friendly technology. A number of models focus on a systematic process for design, using task analysis to evaluate the cognitive processes involved with a given task and develop adequate interface capabilities. Task analysis in past research has focused on the evaluation of cognitive task demands, concerning motor control and cognition during visual tasks such as operating machinery, or the evaluation of attention and focus via the analysis of eye saccades of pilots when flying. Neuroergonomics, a subfield of cognitive ergonomics, aims to enhance human-computer interaction by using neural correlates to better understand situational task demands. Neuroergonomic research at the university of Iowa is currently involved with assessing safe-driving protocol, enhancing elderly mobility, and analyzing cognitive abilities involved with the navigation of abstract virtual environments.

Famous quotes containing the word history:
“So in accepting the leading of the sentiments, it is not what we believe concerning the immortality of the soul, or the like, but the universal impulse to believe, that is the material circumstance, and is the principal fact in this history of the globe.”
—Ralph Waldo Emerson (1803–1882)
“It gives me the greatest pleasure to say, as I do from the bottom of my heart, that never in the history of the country, in any crisis and under any conditions, have our Jewish fellow citizens failed to live up to the highest standards of citizenship and patriotism.”
—William Howard Taft (1857–1930)
“All history attests that man has subjected woman to his will, used her as a means to promote his selfish gratification, to minister to his sensual pleasures, to be instrumental in promoting his comfort; but never has he desired to elevate her to that rank she was created to fill. He has done all he could to debase and enslave her mind; and now he looks triumphantly on the ruin he has wrought, and say, the being he has thus deeply injured is his inferior.”
—Sarah M. Grimke (1792–1873)
