This study investigates the effect of a novel display mechanism, named “persistence display”, on visual sensitivity to changes in graphical gauges. The effectiveness of the persistence display was evaluated under different magnitudes of level changes and was compared to traditional displays that are prevalent in the process control industry. The results of this study show that persistence display increased the users ‟ visual sensitivity such that their ability to detect changes in graphical gauges was greater compared to traditional forms of display across all level of change magnitude. Further recommendations are made to continue evaluating the effect that persistence display may have on operators training
