Application of Coding Methods in Development of Symbology for a Computer-Generated Topographic Display for Army Aviators.

Abstract

This report presents the results of a literature review conducted to identify previous research that could provide guidelines during the initial design of a new symbol system for topographic and tactical data display. Methods of symbol design based on ten dimensions of visual coding -- shape, alphanumeric, size, numerosity, inclination, brightness, color, flash rate, stereo depth, and apparent movement -- are identified and evaluated. The evaluation of alternative coding methods is based on three design-oriented criteria: amount of information conveyed, types of data coded, and aid to operator visual search. These criteria are considered in the review of research investigating both unidimensional and more complex multidimensional symbol systems. A model is presented which identifies the relationships between many factors and symbology system characteristics that ultimately affect the design of symbol systems. (Author)
