Air traffic control weather radar displays: Validation of a masking metric for prediction of text block identification (2001)
Background: The Federal Aviation Administration is evaluating the potential benefits of weather information overlaid on the Terminal Radar Approach Control (TRACON) radar display. The study's objective was to validate a background masking metric to assist display designers to identify good color combinations for an air traffic control weather radar display. Methods: A uniform gray pattern and two weather radar displays were used as the background for randomly selected aircraft data text blocks positioned in eight fixed locations around a central location. The observers' task was to search for the data text block that matched the text block presented in the central location. Four text contrast levels were used for the uniform background and two levels were used for each of the weather radar backgrounds. Results: Percent correct responses and response latency were plotted as a function of the equivalent contrast based on a simple luminance contrast metric. Conclusions: The metric is a fairly good predictor of the masking of the text blocks by the colored weather map backgrounds.
