At the present, the Army has a standard symbol test FM 21-30 for use in portraying critical information on graphic battlefield displays. It has become apparent that this symbology does not include all concepts that are required and of course, there may be some alternative symbols that would be better for use. Thus, there is currently a need for guidance on both future symbology development and for modification of the existing symbol set. A major goal of this research is to provide human-factors based criteria as a basis for selecting among candidate symbols for inclusion in an existing symbology data base the Armys conventional symbols, FM 21-30. In choosing a candidate symbol to represent a particular military concept, at least two factors must be considered 1 the meaningfulness of the symbol, i.e., how well does the symbol portray its referent and 2 the discriminability of the symbol, as reflected in the speed and accuracy of detecting andor identifying the form, in relation to the existing symbol domain. In summary, to insure optimal symbol discriminability, the following criteria could be applied to symbols to resolve symbol conflicts Simplicity, Figure-to-ground relationship, Figural unity, Closure, Continuity, and Symmetry.
