Abstract:

The present study was conducted to investigate the effect of geometry on symbology recognition. Military situations require symbology sets that are consistent with the encoded information being presented in electronic display systems. Often, the mission requirements dictate the need for either shape coding methods or other methods to encode the information desired. The effects of geometry on symbology recognition have been previously studied, but continued research must be accomplished in order to establish a standarized symbology set for use in electronic display systems. The major independent variable in the research study was the geometric shape of a particular symbol. The four symbols investigated were the polygon, diamond, square, and triangle.
