ABSTRACT
Consider some typical situations investigated by ergonomists. First, an operator at a remote control task who must carry out a job from a vantage point not used before, trying to get oriented and to guide the system through its critical operations in the most reliable, safe, effective manner. Second, a factory worker at an industrial machining center who must try to understand why parts she is producing are showing hairline cracks, and what combination of the many parameters available on the machine would solve the problem. Third, a team responsible for scheduling a transport system from a control center, coping with a variety of visual and auditory on-line communications and also using their knowledge of operating procedures. Fourth, a maintenance engineer of a continuous process plant trying to integrate information from system diagnostics with data from historic print out and what he can see from visual inspection.
