Adaptation du design des visualisations de type supervisions pour optimiser la transmission des notifications classées par niveau d’intérêt

Abstract : Air traffic control is undergoing a great change due to the increase of traffic and the evolution of the control tools. The greater number of aircrafts managed by the controller implies a much greater load of information to deal with and memorize than before. A significant part of accidents’ causes is already due to the problem of information perception and memorization which is worsened by the size of the control screens which are particularly critical concerning the perception of alarms and warnings displayed on the radar image. The current design in France of those types of alerts which rely on color is controversial and an Aviation Safety bulletin recommended it should be improved. The perception of information contributing to a satisfactory situation awareness by the air traffic controllers is central to this thesis which aims at making sure alarms and relevant information are detected early enough and according to priorities and that the corresponding actions are actually performed. To answer the issue at stake our first work focus dealt with the study of the controllers’ task so as to analyze the required information in order to achieve certain objectives and provide a task monitoring agent that could support them. The second work focus dealt with the notifications perception, more specifically in the peripheral vision and the conception of designs such as to improve their perception and the study of their impact on the performance of the task. Thanks to a holistic approach based on the use of an ATC microworld (Laby) and the use of physiological sensors we managed to assess several notification designs. Several experiments have been conducted, one using eye-tracking aimed at measuring attention capacity of five designs and their impact on the performance of the task. The second used neurophysiologic data and aimed at measuring the impact of two designs on the work load. The assessed designs enabled to conceive a notification system integrated in a new radar supervision together with the task monitoring agent. The last experiment conducted in the course of this work aimed at measuring the impact of this new position of control whose design is situation awareness oriented, on the detection of critical problems. The obtained results show the relevance of these new tools and their positive impact on the performance of the task by controllers as well as the need to assess, in a controlled experimental context, the characteristics of notification designs for supervision visualization.
