Research on the Effect of Cockpit Knob Interface Layout and Position on Change Blindness

Abstract

The phenomenon of change blindness in the process of aircraft flying is easy to cause pilots to miss the key information prompt, resulting in huge safety risks. In order to ensure flight safety by reducing the occurrence of change blindness, this research adopts the forced detection paradigm and eye tracking technology, combining keystroke accuracy, reaction time, average fixation time, fixation point number to explore stimulus presentation time, knob interface layout complexity, and influence of the position of the knob on change blindness. Therefore, it provides theoretical guidance on how to reduce the incidence of change blindness. The results showed that increasing the time of stimulus presentation could improve the efficiency of change detection and reduce the probability of change blindness. The more concise and reasonable the knob interface layout is, the more beneficial it is in reducing the cognitive load of the subjects and improving the change detection ability of the subjects, thereby reducing the incidence of change blindness. The subjects tended to devote more attention to the central knob, and the identification and processing of information were more comprehensive, meaning the success rate of change detection was higher. It is also proved that there is no interaction between these factors.
