Abstract : The study sought to determine the nature and composition of the display-observer interface. Twelve air defense command and control visual information displays, representing all combinations of three densities of air threat, two different primary formats, and two conditions of information coding, were exposed to subject groups of three different degrees of experience and familiarity with the displays and the tactical concepts involved in their use. Independent multidimensional scaling analyses were performed on the data derived from each subject group. Seven fundamental dimensions, which were congruent across the subject groups, were derived. The patterns of factor loadings suggested interpretations along the lines of: (1) stimulus numerosity, (2) primary coding, (3) contextual discrimination, (4) structure scanning, (5) critical relationships, (6) cue integration, and (7) cognitive processing. These are consolidated into a model, which may serve as a basis for understanding the display-observer interface. (Author)
