Les futurs véhicules permettraient l'alternance entre des phases de conduite autonome et des phases de conduite manuelle. Cette transition est cruciale sur le plan attentionnel et repose sur l'utilisation d'alertes. La littérature a montré que des omissions de perceptions d'alertes sonores peuvent être liées à un niveau élevé d'engagement attentionnel dans une tâche annexe. L'objectif de ce travail en cours est d'investiguer les conditions de création du phénomène d'omission, ainsi que l'efficacité d'une contremesure pour réguler ces états (ici un biofeedback temps-réel du rythme cardiaque). Les participants ont réalisé une double tâche consistant en une détection d'alertes sonores et en un jeu mnésique présentant des variations de difficulté et de stress. Des données physiologiques, subjectives et comportementales ont été collectées. Les premiers résultats montrent un impact des conditions sur les trois dimensions. La poursuite de l'analyse des données devrait nous permettre d'étudier sous divers angles les phénomènes attentionnels et les impacts du biofeedback générés lors de l'expérimentation.

Background: Stress can frequently occur in the driving context. Its cognitive effects can be deleterious and lead to uncomfortable or risky situations. While stress detection in this context is well developed, regulation using dedicated advanced driver-assistance systems (ADAS) is still emergent. Objectives: This systematic review focuses on stress regulation strategies that can be qualified as “subtle” or “mindless”: the technology employed to perform regulation does not interfere with an ongoing task. The review goal is 2-fold: establishing the state of the art on such technological implementation in the driving context and identifying complementary technologies relying on subtle regulation that could be applied in driving. Methods: A systematic review was conducted using search operators previously identified through a concept analysis. The patents and scientific studies selected provide an overview of actual and potential mindless technology implementations. These are then analyzed from a scientific perspective. A classification of results was performed according to the different stages of emotion regulation proposed by the Gross model. Results: A total of 47 publications were retrieved, including 21 patents and 26 studies. Six of the studies investigated mindless stress regulation in the driving context. Patents implemented strategies mostly linked to attentional deployment, while studies tended to investigate response modulation strategies. Conclusions: This review allowed us to identify several ADAS relying on mindless computing technologies to reduce stress and better understand the underlying mechanisms allowing stress reduction. Further studies are necessary to better grasp the effect of mindless technologies on driving safety. However, we have established the feasibility of their implementation as ADAS and proposed directions for future research in this field.
