ABSTRACT
Performance of an operator is highly dependent on the location and arrangement of displays and controls. A well-designed interface takes into account the positioning and grouping of displays and controls, and the relationships between displays and their associated controls. The display arrangement should allow the operator to detect and identify critical visually displayed information with minimal effort. This information needs to be in a form that can be associated easily with the appropriate control that affects the system function captured by the display. The control should be located where it is readily accessible and can be operated comfortably. To accomplish these goals, the display and control arrangements need to be designed according to principles of perception, response selection, motor control, and biomechanics.
