Abstract : Research was conducted to determine the more important criteria that dot-matrix displays intended for use in aircraft cockpit environments should satisfy in order to be compatible with pilot visual perception and information cognition requirements. Techniques to process and display both rapidly time changing and moving numeric information are presented. The legibility performance of developmental programmable legend switch displays is described including the effect of and methods for masking the appearance of fingerprints. Information processing and display techniques for enhancing the appearance of dot-matrix imagery under both translation and rotation are introduced in association with the description as a result of testing developmental video and color dot-matrix displays are also provided. Inconsistencies encountered with existing military grey scale requirements and with the methods currently being developed to objectively describe colors were evaluated and described. No degradation in pilot performance attributable to the dot-matrix nature of the display media was revealed by the experiments conducted. The total number of picture elements (pixels) available to present information was assessed as being the criteria issue that is primarily responsible for establishing both the objective performance capabilities of dot-matrix displays and their aesthetic appeal.
