Manned System Performance as a Function of Display Characteristics.
Abstract
In manned systems, performance can change significantly with changes in display design. With today's computer and display technology, it is possible to provide virtually any display function desired including automating many of the information processing tasks previously preformed by the human operator. However, the relationship between display design and total system (man and machine) performance must be known in order to systematically select the display features. A new human operator modeling technique termed 'operator measures and criteria' (OMAC) was used to represent the ship control performance of the Officer of the Deck (OOD). OMAC's are measures and criteria which are determined by calculation to be those optimized by the observed OOD controlled ship responses. OMAC's were determined from data obtained from an experiment in which three different displays were used. With each of those displays, OOD subjects demonstrating superior performance resulted in identical criteria, but an apparently self-imposed constraint called purview (range from own ship within which contacts are processed by the OOD). was shown to be different for each display type. Purview is shown to explain differences in performance with different displays. The proportion of OOD subjects demonstrating superior performance is also shown to be a function of display type.
