Human Factors Engineering

… the scientific discipline concerned with the understanding of interactions among humans and other elements of a system, and the profession that applies theory, principles, data, and other methods to design in order to optimize human well-being and overall system performance.

Definition adopted by the International Ergonomics Association and the Human Factors and Ergonomics Association

Human Performance and Safety In Various Domains

Aviation: aircraft accidents Medicine: patient injuries and mortalities Manufacturing: defects Power Generation and Distribution:

blackouts Surface Transportation: auto/truck accidents Water Transportation: boat/ship accidents Workplace: occupational injuries etc.

Human Factors Engineering

considers Human Factors, factors that influence human performance, Individual Factors, e.g.,

sensory cognitive physical

Group Factors , e.g., composition organization dynamics

Task Factors, e.g., number nature procedure

Equipment Factors, e.g., display colors control placement and dynamics Tools geometry

Environment Factors, e.g., illumination temperature vibration

in an attempt to understand and improve human performance and safety so as to improve system performance and safety.

IE 366

13

Human Factors Engineering

learns of the effects of human factors on human performance and safety through

Experience (often bad) Research

and develops and applies principles and guidelines to the design of

Equipment, e.g., displays controls tools workstations

Procedures Job performance aids , e.g.,

manuals checklists memory aids

Training programs Selection programs
