Two studies are reported on human performance using military visual iconic objects that increased in complexity by augmenting the number of dimensions. The first experiment demonstrates certain perceptual human biases that appear when attempting to correctly identify the state of a standard military icon feature. The second experiment, based on the results of the first experiment, revealed the expected information overload conditions that occur which give rise to exponential laws. The results of the second experiment provide preliminary guidelines on proper synthesis of new iconic objects in terms of their information complexity as well as how they are perceived by operators.
