Abstract

The invention discloses a controller attention distribution evaluation method based on eye movement data. The method comprises the steps of collecting the eye movement data of a controller in different aircraft number scenes in the control execution process and subjecting the data to denoising processing; distinguishing the denoised eye movement data by utilizing an eye movement algorithm; selecting an eye movement index reflecting attention distribution of the controller; and analyzing the change characteristics of the selected eye movement indexes by utilizing statistical analysis and a multi-fractal detrending wave algorithm to evaluate the attention distribution of the controller. According to the method, the change of the eye movement data of the controller facing the control scene iscombined with the related algorithm, so that the optimal controller attention related index is obtained, and the controller attention distribution characteristics can be effectively evaluated.

Description

technical field [0001] The invention relates to an eye movement data-based attention distribution evaluation method for controllers, and belongs to the technical field of attention evaluation. Background technique [0002] Civil air transportation occupies a unique position in the transportation industry by virtue of its advantages of safety, speed, comfort and freedom from terrain restrictions. With the rapid development of the aviation manufacturing industry, the demand for civil air transportation is increasing year by year, and the environment of civil air transportation is becoming more and more complex, resulting in the increasing difficulty of air traffic control tasks. As the manager of the control sector, the controller's behavior directly affects the operation of the entire air traffic system. The increase in air traffic flow and the complexity of the control scene will increase the difficulty of the controller's work and increase the probability of the controller...
