Abstract:

The study was designed to determine if variations in the distance between a control and its associated display affected control activation time. The time required to activate toggle switches was measured with control-display separations of 1.27 cm0.5 in., 3.81 cm1.5 in. and 6.34 cm2.5 in.. The mean control activation times and their associated standard deviations were not differentially affected by the control-indicator distances used in the study. Author
