Combining check-reading accuracy and quantitative information in a space-saving display
AbstractAn experiment investigated the possibilities that a check-reading display could be designed to yield quantitative information, and that a more compact format could be used, saving space while preserving information content. The commonly used 4 X 4 display matrix and 0.50 sec. exposure time were used. Application of Gestalt principles proved advantageous. In an earlier study the principle of continuity was found highly efficient for qualitative readout. In this case, the principle of similarity of form was found to allow quantitative readout with little or no loss of check-reading efficiencies, which ranged between 94% and 98% correct detection of errors. Compressing the display by use of semicircular, rather than circular, dials improved performance even beyond its earliest, almost perfect, level.
