The study was designed to investigate performance of a two-hand coordination task as a function of the direction of station of the controls in relation to the direction of movement of the display. The SAM Two-Hand Coordinator was modified so that a the effect of the direction of rotation of the crank on the movement of the display could be reversed and b the cranks could be placed in either the vertical or horizontal plane. These results indicate that in the design of equipment controls where control cranks must be turned simultaneously by the two hands, superior performance will result if there is continuity between the plane and direction of movement of the controls, and the plane and direction of movement of the display.
