Outlined “man-computer symbiosis”

The hope is that, in not too many years, human brains and computing machines will be coupled together very tightly and that the resulting partnership will think as no human brain has ever thought and process data in a way not approached by the information-handling machines we know today.”

Human Computer InteractionHuman Computer Interaction

A discipline concerned with the design, implementation, and evaluation

of interactive computing systems for human use and with the study of major phenomena surrounding them.

Why study human use of computer Why study human use of computer systems?systems?

Business view: to use humans more productively/effectively the human costs now far outweigh hardware and software

costs Personal view:

people view computers as appliances, and want it to perform as one

Marketplace view: everyday people using computers

now expect “easy to use system” not tolerant of poorly designed systems little vendor control of training heterogeneous group

if product is hard to use, people will seek other products

            

Department of Computer Science and Engineering, Hanyang University

Why study human use of computer Why study human use of computer systems?systems?

The system view: complex human complex computer complex interface between the two

The human factors view: humans have necessary limitations errors are costly in terms of

loss of time loss of money loss of lives in critical systems loss of morale

design can cope with such limitations!

Why study human use of computer Why study human use of computer systems?systems? The social view: Computers contribute to critical parts of our

society, and cannot be ignored educate our children take medical histories and provide expert advice keep track of our credit worthiness play(?) war games (and help form policies) control air and ground traffic flow book travel control chemical/oil/nuclear plants control space missions assist humans with their everyday tasks (office automation) control complex machines (aircraft, space shuttles, super

tankers) help control consumer equipment (cars, washing machines) entertainment (games, intellectual stimulation).…

In all these views, economics and human best interests are aligned
