Représentation partagée et travail collaboratif en contexte C2 : monitoring d'opérateurs en situation simulée de command and control.

Abstract : Advances in information and communication technologies has enabled the development of collaborative work in almost all sectors of human activity. To ensure the performance of the group and minimize the risk of errors, it is crucial that the team members share a common understanding of the situation in which they are involved. This is particularly true in military crisis situations, such as those that exist within command and control (C2) structures.Within an environment characterized by the growing complexity of conflicts, the challenge today is both scientific and highly applicative. Progress in the study of collective cognition, the heart of collaborative work, has a clear potential that must be translated into tangible applications to optimize the management and execution of collective tasks. Real-time evaluation of the cognition of individuals and teams allows to envisage adaptive tools and systems to improve efficiency, performance and agility.In light of these challenges, our objective, commissioned by the DGA, is to find appropriate measures that would enable an assessment of the dynamics of the sharing of situational awareness, in the very constraining context of command and control room operations, which require the lowest possible level of instrumentation of operators.Our contribution to the field has been dual. We have proposed the concept of situation awareness synchrony to support the theoretical development of the study of the dynamics of situation awareness sharing. In addition, we have highlighted the importance of adopting a cognitive engineering methodology, in the perspective of transposing laboratory knowledge to a more complex application environments.Thus, our work consisted in exploring quantitative measures of shared situational awareness, suitable for automated and real-time exploitation by a collective cognition diagnostic system. We applied psychophysiological and behavioural monitoring of operators engaged in a C2 task (individual, then collective), to evaluate their shared situation awareness, using eye tracker pupillometry.These studies have led us to analyze the sensitivity of this monitoring to the dynamics of the operators' situational awareness and its sharing in an ecological environment.This doctoral work is presented as a demonstration of the interest and applicability of shared cognition evaluation systems in realistic collaborative work environments, and is supported by proposals concerning the future of research on C2.
