This report summarizes the available information concerning several techniques of control coding which seem to be of value to the design engineers. Control coding means providing the operator with a way of identifying the controls. Five methods of control coding are discussed: Shape coding, size coding, location coding, color coding, and mode-of-operation coding. Information is given concerning each coding technique so that the design engineer can apply any of these methods as the need arises. Many of the advantages and disadvantages of each method are pointed out. The question of when to code and the type of coding to use are discussed.
