Effect of Background/Foreground Color Coding on Detection in Acoustic Data Displays

摘要

Considerable work is going on to determine how color should be used to improve the legibility of sonar CRT displays. One of the questions concerns the color that should be used for the background on such displays. Some operators have expressed the opinion that a blue background is preferable to the standard black background because blue is less fatiguing and may enhance target detection. In this study, the ability of experienced sonarmen to detect red, yellow, and green target tracks of equal contrast on blue and black backgrounds was measured on a simulated sonar display. There were no differences in the detectability of the different targets on the two backgrounds, and there was no agreement among the operators as to the best color combinations.
