Identification of Color Coded Target Lines of Different Orientations on CRT Screens

Abstract

Current passive broadband sonar 'waterfall' displays are monochromatic, but color may be added in the future. One possible use of color would be to have the operator assign different colors to the different target tracks. The speed and accuracy of matching a colored target line on a CRT to a standard set of colors was measured as a function of the orientation of the target line. With lines one pixel wide, performance was significantly worse for diagonal than horizontal or vertical lines. There were no significant differences with the width of the line was doubled. Performance was not affected by the presence of colored distractor lines.
