Optimization of Fighter Head-up Display Layout Based on Fitness Function

This study improves the HUD interface layout optimization method which is based on the proposed fitness function. The improved optimization method is more feasible and stable. According to the proposed optimized fitness function and the method, the HUD interface layout in the take-off phase and the cruise phases of the fighter were adjusted. The speed area, latitude area, center area of the HUD interface in take-off phase and the speed area, latitude area, central area, head area in cruise phase were expended in the optimization. The eye movement data of the subjects on the HUD interface before and after optimization were measured by the eye tracker. The eye movement data showed that the subjects’ attention distribution on the optimized interface was more uniform, and the subjects could access critical information with less cognitive load.
