Influence of color lightness change on personnel identification performance in ship background environment for a long time.

This research according to the operating personnel use requirements, combining space variant adaptive technology and graphical interface technology, using the self-developed coding test system, according to the basis of the elements to reaction time and accuracy as performance indicators to carry out the experiment, by testing the subjects in the ship for a long time background environment for different coding identification of display elements. This paper analyzes and interprets the influence mechanism of operators' working ability change on basic display element coding. The experimental results show that when people are in the background environment of ships for a long time, the interface identification performance of people decreases due to the decrease of working ability, and the corresponding optimal color contrast changes from about 80% to about 60% when the reaction time is minimum. The experimental results are in line with the experimental hyp.
