A note on measuring human functions in systems

Abstract:Abstract.— Performances in different man-machine system functions are usually not directly comparable: It is suggested that some functions may be measured through quantities corresponding to β and d' of the signal Detection Theory. Necessary assumptions are that the task can be reduced to a binary decision and that the decision depends upon a subjective value of certainty which vanes in one dimension. The method of measurement is illustrated by an example with a hypothetical system comprising three functions: detecting, identifying and interpreting.
