Abstract:
Objective:To observe the attention processing characteristics of the pilots experiencing black hole illusion, and to provide quantitative data references for flight simulation training guided by eye movement fixation based on the eye movement mode of the pilots with high flight performance score.Methods:The pilots who underwent the transformation training were selected by cluster sampling. Their original flight performance scores were converted into percentile grades. The top 10 and bottom 10 pilots were assigned as high and low score groups. Their eye movement data were recorded when they were completing the night approach and landing task on the flight illusion simulator. The correlation between eye movement data and flight performance in the simulation task were analyzed, and the eye movement patterns of pilots with different flight performance were compared.Results:Thirty-six valid subjects were selected. A total of 12 eye movement indexes were correlated with flight performance ( r=0.334-0.398, all P<0.05). Three eye movement indexes, including peak velocity of exit saccade from attitude indicator of head-up display (HUD), the percentage of total duration of fixations on airspeed indicator of HUD to the total task duration and average duration of whole fixations on attitude indicator could establish a linear regression model with flight performance ( R2=0.422, F=7.77, P<0.001). The percentage of total duration of whole fixations on airspeed indicator of HUD to the total task duration in high score group [(4.38±3.48)%] was higher than that in low score group [(1.72±1.32)%], and the difference was statistically significant ( t=2.25, P=0.045). And the average peak velocity of exit saccade from attitude indicator of HUD in high score group [(358.85±171.40)°/s] was higher than that in low score group [(221.14±92.60)°/s], and the difference was statistically significant ( t=2.24, P=0.038). Conclusions:Eye movement index in the night approach and landing task can be used as an evaluation index of attention ability of pilots in black hole illusion simulation and experience task.
