Abstract

The purpose of this work is to present the first attempt to provide quantitative analysis and objective justification for designers' decisions that relate to the arrangement of pilot indicators on an aircraft dashboard with the use of video oculography measurements. To date, such decisions have been made only based on the practical experience accumulated by designers and subjective expert assessments. A new method for optimizing the mutual arrangement of the dashboard indicators is under consideration. This is based on iterative correction of the gaze transition probability matrix between the selected zones of attention, to minimize the difference between the stationary distribution of relative frequencies of gaze that are staying in these zones and the corresponding desirable target eye movements that are given for distribution for qualified pilots. When solving the subsequent multidimensional scaling problem, the gaze transition probability matrix that is obtained is considered to be the similarity matrix, the elements of which quantitatively characterize the proximity between the zones of attention. The main findings of this novel work are as follows: the use of oculography data to justify dashboard design decisions, the optimizing method itself, and its mathematical components, as well as analysis of the optimization in question from the viewpoint of quantum representations, all revealed design mistakes. The results that were obtained can be applied for prototyping variants of aircraft dashboards by rearranging the display areas associated with the corresponding zones of attention.

To optimize the format of the screen display based on the analysis of the movements of the pilot's gaze on the attention zones, five zones were selected on the stimulus material

Summary

Introduction

The human factor, along with the effectiveness of professional training, is recognized as one of the main factors in the emergence of critical situations in civil aviation. According to some expert evaluations, for the past two decades pilots have been participating in the control process for only several minutes on average during each flight, the number of accidents that result from crew errors is up to 65%. These factors and their impacts on the emergence of critical situations in flight should be taken into account in shaping the information and control field of a crew cockpit. The main direction of this activity is the assessment that is based on the results of work on modern simulators and test benches, where it is possible to repeat the special conditions of pilots' work without too much difficulty
