10. IE 366 10 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

11. IE 366 11 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.

12. IE 366 12 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.

13. 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
