Research works on operator monitoring underline the benefit of taking into consideration several signal modalities to improve accuracy for an objective mental state diagnosis. Heart rate (HR) is one of the most utilized systemic measures to assess cognitive workload (CW), whereas, respiration parameters are hardly utilized. This study aims at verif...

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...

This article explores the influence of personality on physiological data while driving in reaction to near crashes and risky situations using Machine Learning (ML). The objective is to improve the driving assistance systems in considering drivers’ characteristics. Methods Physiological and behavioral data were recorded in sixty-three healthy volun...

The incorporation of empathic systems in everyday life draws a lot of attention from society. Specifically, the use of wearables to perform stress regulation is a growing field of research. Among techniques explored, the haptic emulation of lowered physiological signals has been suggested to be promising. However, some discrepancies remain in empir...

Full text available at : https://theses.hal.science/tel-04146982 Stress is a phenomenon frequently encountered in driving. It can affect the safety and comfort of users. Driving automation offers new ways to improve safety and reduce the danger posed by some human factors. However, it can also result in the concomitant occurrence of non-driving re...

Climate change represents a major challenge, highlighting the critical role of renewable energy sources (RES). Despite efforts to reduce CO2 emissions, RES face difficulties such as social rejection, stressing the importance of raising public awareness about their benefits. Advertisement campaigns may be key in shifting attitudes towards RES. This...

Stress impacts driving-related cognitive functions like attention and decision-making, and may arise in automated vehicles due to non-driving tasks. Unobtrusive relaxation techniques are needed to regulate stress without distracting from driving. Tactile wearables have shown efficacy in stress regulation through respiratory guidance, but individual...

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 attention...

The present work investigates the cardiovascular activity linked to the cognitive workload induced by the realisation of a supplemenary mental task to driving in a simulator. Specifically, heart rate (HR) and heart rate variability (HRV) are computed to establish the physiological modulations under different types of cognitive demands defined accor...
