Simplification of the Panel layout on Standard Series Tank Radios

摘要

This study evaluates the effect on operator performance of modifying the tank radio, in certain minor ways. The selection of modifications employed in the study was limited to those which could be made by the using units.nThe purpose of this study was to evaluate the hypothesis that increasing the distinctiveness of controls through coding will result in a reduction of errors made during radio operation.nThe mean performances of the three-color group and the numeral group were higher than those of the corresponding control groups. Also, more men in these experimental groups than in the corresponding control groups obtained the perfect score necessary to establish radio communication.
