What Is the Field of Human Factors?
► Ambiguous
communications: a U.S. Navy cruiser
in conflict-ridden Persian Gulf
► Goal
(1/3)
of human factors
Enhances performance: productivity, error
Increases safety
Increases user satisfaction
Human factors involves the study of factors and
development of tools that facilitate the
achievement of these goals
What Is the Field of Human Factors?
► The
cycle of human factors
(2/3)
Figure 1.1
Identification of Problems
Analysis Tools: task analysis, statistical analysis,
incident/accident analysis
DESIGN
−
Equipment design: physical equipment
−
Task design: what operators do
−
Environmental design: lighting, temperature, noise,…
−
Training: better preparing
−
Selection: individual differences

Human factors vs. Engineering psychology
−
Ultimate Goal:
Human factors: toward system design
Engineering psychology: understand human mind as is
relevant to the design of systems
−
Emphasis:
Engineering psychology : discovering generalizable
psychological principles and theories
Human factors : usable design principles
The Study of Human Factors as a Science
► Generalization
and prediction
(e.g.) Communications

Air traffic control center and the aircraft
Workers on a noisy factory floor
Doctors and nurses in an emergency room
► Nature
of observation
Laboratory: highly controlled observations and
experiments
Human behavior of real users of real systems
Most effective: from lab to real environment
An Overview of the Book
► Four
basic sections
Different research techniques & design
methodologies. (Ch.2, 3)
The nature of human information processing.
(Ch.4-9)
The nonpsychological issues of human factors.
(Ch.10-14)
Specific domains of application of human factors.
(Ch.15-19)
