AN EXPERIMENTAL INVESTIGATION OF INTELLIGENCE INFORMATION DISPLAY PARAMETERS.
Abstract
The present study was undertaken to evaluate the effects of three (color, density, and task) of the many parameters which have relevance to the performance of AF intelligence analysts using tabular, graphic, and cartographic displays. The results (based on extensive data from 68 subjects) have at least limited application to improvement in the design of AF intelligence (or command and control) displays: (a) A useful upper limit to the number of symbols or symbol classes (density of information) is indicated; (b) Using color to enhance the distinguishability of display symbols appears ineffective; and (c) Graphic representations are preferred for rapid decision making, whereas tabular displays are more effective where accuracy is stressed. To assume greater ealidity, the above conclusions should be verified within an operational setting which conforms to the types of displays and tasks comprising the study. (Author)
