Document Summary

Chapter 1 ergonomics is derived from the greek words ergo (work) and nomos (laws). First maxim: the primary purpose of human factors and ergonomics is design. Second maxim: in hfe, a systematic, interdisciplinary approach is necessary for design and analysis. Human factors and ergonomics coming close b/c computers in workplaces. Opportunity got improvements or modifications; needs, abilities, limitations, constraints. Hfe- considering environmental and organizational constraints: use knowledge of human abilities and limitations, to design the system, organization, job, machine, tool, or consumer product, so that it is safe, efficient, and comfortable to use. Ergonomics- understand/model human behavior to optimize well-being and overall system performance. No washers in design so that robots can do the full assembly and humans are not needed- robots have constraints. Human centered design -rosenbrock - make machine- repetitive tasks and humans- interesting tasks. Seen as a tool for exploiting workers do mindless repeative job-> become mindless.
