Methodology/measurement: papers that emphasize ways of answering HFE questions or solving HFE problems. Safety: closely related to IE but with a major emphasis on analysis and prevention of accidents. System design/development: papers related to the processes of analyzing, creating, and developing systems. Training: papers describing how personnel are taught to perform functions/tasks in the human–machine system.

1988), the lack of compatibility, or ergonomics incompatibility (EI), defined as degradation (disintegration) of the artifact– human system, is reflected in the system’s measurable inefficiency and associated human losses. In order to express the innate relationship between the systems’s complexity and compatibility, Karwowski et al. (1988, 1991) proposed the complexity–incompatibility principle, which can be stated as follows: As the (artifact–human) system complexity increases, the incompatibility between the system elements, as expressed through their ergonomic interactions at all system levels, also increases, leading to greater ergonomic (nonreducible) entropy of the system and decreasing the potential for effective ergonomic intervention.

Are differences between controls distinguishable by touch? Is the location of controls consistent and is sufficient spacing provided? Have the requirements for the control-display compatibility been considered? Is the type of cursor control suitable for the intended task? Is the direction of control movements consistent with human expectations? Are the control objectives clear from the position of the controls? Are controls within easy reach of female workers? Are labels or symbols identifying controls properly used?
