Abstract : Experiments were conducted to determine whether a multi-dimensional nonredundant means of encoding information for visual displays could be derived from several encoding dimensions. The effectiveness of geometric-only encoding was compared with geometric-plus-brightness level, flashing rate, and color encoding, with respect to speed and accuracy in performance of two different tasks. Nonredundant use of two and three different colors was found to improve speed and accuracy; the combination of several levels of three different encoding dimensions is detrimental to performance, particularly when three flashing rates are included.
