The research was directed toward developing a metric of display quality for evaluation of large-screen displays and toward developing a criterion to validate the metric. Two approaches were used. In the first, multidimensional analysis MDA was used to test the hyopthesis that, other things being equal, display quality was related to the number of perceived dimensions of information content the results of the test failed to support the hypothesis. In the second approach, a game situation was used in which the monetary value of the subjects decisions could be calculated. Several display parameters, including format, information density, and color, were manipulated. The monetary value of the decisions, or decision value was found to be a reliable and valid measure of display quality. It is recommended that MDA and decision quality be combined to formulate a predictive model of display quality. Research to this end should be conducted using a wide range of stimuli and subject proficiency levels. Author
