Abstract
-
This experiment summarizes a series of experiments designed (1) to investigate the effects of certain control-display relationships on making settings with moving-scale instruments, (2) to attempt to find the optimum control to moving-scale display relationship.Two recommendations resulted: (1) Moving-scale assemblies, for use where the operator will never make control adjustments without simultaneously looking at the associated display, should have a dial which rotates in the same direction as its control knob and whose scale numbers increase from left to right. At least two scale numbers should be visible in the display aperture at all times. (2) When the operator may make crucial control adjustments by "blind reaching" (i.e. without looking at the display), moving-scale assemblies should not be used.
