The Polarity Coincidence Correlation Technique - A Useful Tool in the Analysis of Human-Operator Dynamics

The paper describes a special correlation technique. It is shown that a two-state characterization of a random process leads to a simple correlation procedure, called the "polarity coincidence correlation method." The utility of the method in dynamics studies of man-machine systems, its limitations, its assumptions, and, finally, the accuracy due to a finite time of observation are discussed.
