A Detection Theory Method for the Analysis of Visual and Auditory Displays

A signal detection method for evaluating different display codes and formats is described. The method allows one to determine how an observer aggregates information from multiple element displays. The method can be used to assess the relative importance of specific spatial or sequential elements of the display. The efficacy of different formats and arrangements thus can be compared. The paper describes the theoretical basis for the method and briefly summarizes data from several types of visual and auditory displays.
