RADAR SYMBOLOGY STUDIES LEADING TO STANDARDIZATION: II. DISCRIMINATION IN MIXED DISPLAYS

Abstract

The report covers continued studies toward standardization coding symbols for an information display. Experiments were directed toward locating 'the most readily discriminated five-symbol code complex' as measured by errors and location times. Experiment 1 attempted to simplify testing procedures by using a card sorting task. The same five-symbol code was presented as a black- on-white simulated display in Experiment 2. Results were not comparable and the simulated display was used in further experiments with a variety of codes. Legibility and association values of individual forms varied with the population of shapes within the code complex. Experimental results led to general recommendation for code design.
