How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

Our paper aims to redefine the concept of stress in the context of maintaining allostasis; the term has been reserved for situations that concomitantly involve established physiological and psychological stress components. In particular, we analyze how novelty, unpredictability, threat to the ego, and low sense of control challenge allostasis. The...
This paper presents PHYSIOSTRESS, our data corpus of acute stress and physiological activation. It includes 26 experiments of acute stress based on the Trier Social Stress Test, and 24 experiments which combine a social task and a physical activity. These experiments were accomplished by 13 men and 13 women between 20 and 49 years old without ident...
This paper presents the system that we have developed for the AV + EC 2015 challenge which is mainly based on deep neural networks (DNNs). We have investigated different options using the audio feature set as a base system. The improvements that were achieved on this specific modality have been applied to other modalities. One of our main findings...
This paper proposes a new kinematic controller for the waypoints guidance of robotic mobile platforms. A notable feature of the controller is its ability to process the raw sequence of waypoints to produce smooth reference velocities from control laws that are derived by taking into account a driving profile including the velocity limits, the accel...
Background Many people with mobility impairments, who require the use of powered wheelchairs, have difficulty completing basic maneuvering tasks during their activities of daily living (ADL). In order to provide assistance to this population, robotic and intelligent system technologies have been used to design an intelligent powered wheelchair (IPW...
This paper presents a new formulation to the waypoints following control of mobile robotic platforms, which directly uses the original waypoints sequence, typically obtained from discrete path planning, in order to achieve proper motion behaviors with regards to speed transitions, overall motion duration and path smoothness. The approach produces r...
Various situations of mobile platform navigation controls require a collaboration between a human agent and autonomous navigation modules. This work presents a new approach for collaborative control between such two agents, based upon a three-layer architecture. An arbitration scheme is proposed in the deliberative layer as well as a collaborative...
We aim at developing a reliable method to measure human stress from ubiquitous sensors of heart, respiratory and physical activity. We are also interested in studying and comparing current measurement approaches from the salivary cortisol, the perceived stress and the felt stress.
