Conception d'une représentation graphique des gestes numériques pour le cockpit tactile fondée sur les dimensions participant à la conscience mutuelle entre les pilotes

Abstract : The flying activity involves close collaboration between pilots. Indeed, even if they share a co-located space, their need for mutual awareness is more a matter of collaboration at a distance. Given the separation of tasks, sometimes they must act and look in opposite directions while ensuring proper coordination of the overall activity. Speech, gestural expressiveness and the disposition of physical controllers are important means of transmitting useful information to the mutual awareness of the situation in the cockpit. However, in airliners cockpits, touch screens are gradually replacing physical controllers. Despite the many advantages of touch-based interactions and dynamic displays, this creates a problem in sharing the information transmitted by the gestures between both the pilots. The gestures are less perceptible and less understandable. The objective of this thesis work is to fill this information gap by proposing a way to represent, within the touch screen, the good properties of physical gestures in order to preserve the pilots' ability to coordinate. To do this, we propose to design a graphical representation system to supplement the actions performed by the pilots on the touch screen. Based on the literature and an analysis of gestural activity, we have identified nine types of information produced by physical gestures that should ideally be reproduced in the interaction with the touch screen. In addition, we conducted a state of the art on the representation of gestures. We proposed an iconic and abstract representation that breaks with représentations based on the morphology of the hand. Representations were designed and evaluated by pilots in participatory workshops. Our work shows a new way of representing gestures and allows us to identify the information needed by pilots so that they are able to ensure their mutual awareness. Moreover, it appears that the representations of gestures have different statuses of importance depending on the situation, sometimes going so far as to be useless.
