Conducts research, development, application, and evaluation of psychological principles relating human behavior to characteristics, design, and use of environments and systems within which human beings work and live: Collaborates with equipment designers in design, development, and utilization of man-machine systems to obtain optimum efficiency in terms of human capabilities. Advises on human factors to be considered in design of man-machine systems, military equipment, and industrial products. Participates in solving such problems as determining numbers and kinds of workers required to operate machines, allocation of functions to machines and operators, and layout and arrangement of work sites. Analyzes jobs to establish requirements for use in classification, selection, placement, and training of personnel [JOB ANALYST (profess. & kin.)]. Develops training methods and materials, such as curriculums, lectures, and films, and prepares handbooks of human engineering data for use by equipment and system designers. May conduct research to develop psychological theories concerning such subjects as effects of physical factors (temperature, humidity, vibration, noise, and illumination) on worker's behavior; functional design of dials, scales, meters, and other instruments to minimize sensory requirements; specifications for optimal size, shape, direction and speed of motion, and location of equipment controls; and effects of environmental, organismic, and task or job variables on work behavior and life quality.
